FOR EDITORS, PROOFREADERS AND WRITERS

Want to mark up greyscale and colour PDFs digitally? My upgraded BSI-compliant stamps now have fully transparent backgrounds and are completely free to download.

Many of my colleagues have been using these PDF proofreading stamps for years. And they worked fine as long as the markup area was white.

However, when it came to annotating tinted elements, the markup looked messy. That's because when I created the stamps back in 2012 – all 113 of them – I took design shortcuts that meant some stamps didn’t have transparent backgrounds.

​I knew some of the stamps weren’t perfect but creating three sets had been backbreaking work and, if I'm honest, I couldn’t face returning to the project and redrawing them.

Eight years on, I decided to review the position. And, in fact, amending the problem stamps turned out to be not nearly as onerous a task as I’d expected.

What the new stamps look like
Below is a mock-up to show you the improvements. All the stamps now have transparent backgrounds, which means you can place them anywhere on the PDF page regardless of whether you’re marking up on white space, tinted boxes or photographs.

Advantages of using stamps
If you're happy with your PDF editor's onboard annotation tools, great; carry on using them.

However, some proofreaders choose to add these stamps to their editing toolbox for the following reasons:

• Their clients want them to use standard marks. The standard in the UK is BS 5261C:2005: 'Marks for copy preparation and proof correction'.
• The symbols facilitate efficient and clear markup when space is limited, or writing an instruction in a comment box would be more time-consuming, or the onboard  markup tool isn't sufficiently precise. 
• Some national editorial societies include digital markup in their core-skills training, e.g. the Chartered Institute of Editing and Proofreading (CIEP).
• The proofreader wants a hybrid tool that facilitates the use of traditional markup language in a digital environment.

If you're starting out on your journey as a professional proofreader and you're marking up PDF proofs, this one's for you.

​There was a time when if a publisher commissioned me for a proofreading project I could expect a large, heavy parcel of paper to turn up in the mailbox. The parcel would contain at least the final page proofs (see Not all proofreading is the same: Part I – Working with page proofs).

If I was required to proofread against copy, the parcel would also include the galley proofs (a printed copy of the pages of raw text supplied by the author on which the copy-editor had marked initial corrections).

Paper proofreading is an expensive business before the publisher has even paid the editorial freelancer’s invoice. And it’s a double whammy – the client has to pay for the proofs (and possibly the galleys) to be delivered to the proofreader, and it has to bear the costs of the return postage.

I’ve worked on large academic books in the past that incurred postage and packaging costs of over £70 per proofreading project. And let’s not talk about the cost of paper and ink.

It’s not surprising, then, that some publishers and project-management agencies have embraced cost-effective solutions. PDF markup has proved to be an effective alternative. Digital delivery costs nothing as long as the client and proofreader already have internet access.

It’s not just good news for the client – the proofreader benefits, too. I live in rural Norfolk and have to drive to my nearest post office. That’s time that I can’t bill for, not to mention the wear and tear on my car (though HM Revenue & Customs does have a mileage allowance). Even so, I have better things to do.

Visits to the post office aside, many proofreaders have found PDF proofreading to be a more efficient task than paper-based work. For those of us working for publishers on a fixed-fee basis per project, this means a better hourly rate.

Given that some publishers haven’t increased their freelance rates for many years (or have done so but only minimally), such efficiencies can mean the difference for the proofreader between continuing the working relationship and waving goodbye to the client.

The proofreader’s options for PDF markup
Most PDF editing software includes onboard commenting and markup tools for annotation purposes so that the proofreader can:

• mark for insertion, deletion and underlining
• draw basic shapes and lines
• highlight and comment
• attach sticky notes
• pin files
• type text and specific instructions to the designer (this typed text can itself be formatted in terms of font, size, alignment and colour, and it can be italicized, emboldened, underlined or struck out)

Stamps (digital proofreading marks) are another option. See 'The Proofreader’s Corner: Using the Stamping Tool for PDF Proofreading Mark-up', An American Editor, September 2015, for an overview of the subject.

The Working Onscreen archive on The Editing Blog has other related content that may be of interest to new entrants to the field.

Platforms include (but are not limited to): Futureproofs (client pays for use of platform), PDF-XChange (considerably cheaper and trusted alternative to Acrobat Pro with excellent functionality), Acrobat Professional (well-known and trusted but expensive) and Adobe Reader (free, and increasingly user-friendly. Latest version is DC).

Potential pitfalls to avoid
Onscreen proofreading can save the proofreader and the client time and money, but there are a number of pre-project steps that should be taken to ensure that the final outcome is a happy experience for all parties.

Making assumptions based on your own preferences, or your colleagues’ experiences, could lead to readability and compatibility problems.

Ask your client what they want
Ask your client what their preferences are rather than making assumptions. Be prepared to be flexible.

Some publishers have streamlined their production processes and have a strict set of guidelines concerning which annotation tools should be used for digital proofreading.

Some clients will be happy for you to use digital stamps based on publishing-industry-recognized markup symbols. Others might insist on sticking to a particular PDF editor’s onboard comment-and-markup tools. Yet others may expect a mixture of both.

Some may even want you to actually edit, rather than just annotate, the PDF (though this is very risky as it could interfere drastically with the layout of professionally typeset page proofs).

Some publishers are experimenting with Futureproofs (which has its own onboard markup system – for a review, see my article Digital proofreading using Futureproofs, November 2015).

I merrily used the onboard commenting tool for a Spanish business client for two years, assuming wrongly that she wouldn't have a clue what the British Standards Institution proof-correction symbols were. She then surprised me by asking whether I knew how to use the “more efficient standard proofreading markup language”. I was happy to oblige, using stamps, because it was quicker for me, but I’d wasted precious time for two years because I’d made a flawed assumption.

Test the platform
Once you've agreed with your client on how you will mark up the PDF, do a small test to check that both of you are seeing the same annotations and that the markup “sticks” during the delivery process.

For example, I wanted to use the stamping tool in PDF-XChange on a recent project with a new client. We agreed in principle that this was acceptable.
​

• I extracted one page from the PDF page proofs and annotated it using several different stamps, the onboard commenting tool and the onboard strike-through, polygon and highlighting tools.
• I then saved the page and opened it up in my recently downloaded version of Adobe Reader DC. All looked well.
• I then compiled a list of all the test changes I’d made (briefly describing the actions and the line/paragraph where they occurred: for example, highlight [word] on line 2, paragraph 2; comment at line 4, paragraph 2; delete stamp in margin and strike-through [word] in text at line, 9, paragraph 3).
• I emailed the list and the marked-up PDF page to my client. He confirmed that all the markup appeared as it should on the software he was using.
  
  

I then felt confident to continue the proofread as planned.

File size
Some marked-up PDFs can be huge.

A client once sent me a PDF of 2,329 KB. By the time I'd stamped it, it was 25,395 KB (I zipped it down to 23,646 KB). 

If your email provider won’t handle large files, you will need to agree an alternative delivery system with your client.

Examples could include setting up a shared file in Dropbox, uploading directly to the client’s ftp site or using the likes of FileZilla, or transferring via an internet-based service such as WeTransfer.

Again, don’t assume that what suits you will suit your client. One of my project managers was happy in principle to use Dropbox (which I have) but then found out via her IT department that she wasn’t allowed to download the software to her PC. We had to work out an alternative.

Up-to-date software
Keep your software up to date. Perhaps Acrobat Standard (version 9) or PDF-XChange Viewer worked for you and your clients three years ago. However, the clients you’ve inherited recently are working with different software or more updated versions of existing tools. Installing regular updates and upgrading to the latest versions can help to reduce the risk of compatibility and readability issues at either your end or your client’s.

A caveat
I’m based in the UK so I’ll be referring to the British Standards Institution’s (BSI) BS 5261C:2005 'Marks for Copy Preparation and Proof Correction' throughout this article (readers can buy a hard-copy list of these marks from the Society for Editors and Proofreaders).

You might be used to seeing different symbols to indicate the same instructions. That’s because, depending on where you live, different standards may apply.
​
Compare, e.g., the Canadian Translation Bureau and BSI marks for a selection of instructions:

What matters is not which proof-correction language you use, but what your client requires.

Why might I need to make my own stamps?
You might wish to create your own stamps for three reasons:
​

• The standard symbols required by your client might not be available for use on PDF. Use the resources in the above recap section in order to identify whether the mark-up language you want to work with is available digitally.
  
  
• The existing digital resources might include only the standard symbols developed by the original issuer (BSI, CMOS, CTB, etc.). However, I’ve sometimes found that I’m repeatedly making a particular amendment that isn’t covered by these standards.
  
  ​For instance, a nonnative-English-speaking author may use the word 'is' when the author means 'are' repeatedly in a file. Rather than annotating the PDF using the typewriter tool for the text, and using the Replace symbol (slash mark) for each correction, it could be more efficient to create a new stamp that incorporates the text and slash mark.
  
  ​In the stamps files I provide, I’ve created several nonstandard symbols that I thought would be of benefit to users, including:

When we modify standard stamps in this way, we save time – every second we save stamping only one symbol rather than two adds up to significant increases in productivity.

Creating your own stamps
There are two ways to go about creating your own customized stamps.

First method
You can using a free snipping tool to copy a mark that you’ve drawn, typed, or found online. If I want to create a new stamp – for example, the 'change is to are' instruction mentioned above – I can use my PDF editor’s comment-and-markup tools to type the word 'are' and stamp a Replace symbol after it.

Then I simply click on my snipping tool, select 'New', and drag the cursor over the marks I’ve made. I then save this as a PNG, GIF, or JPEG. The image is now available for upload into my PDF Editor’s stamps palette.

In Windows 10, the snipping tool looks like this:

Where your snipping tool is located will depend on which version of Windows you’re using.

The advantage of using a snipping tool is that it’s very efficient. I’ve pinned my onboard Windows snipping tool to the task bar at the bottom of my screen, so it’s always accessible. If you are using an operating system that doesn’t include a snipping tool, there are of alternatives available online.
​
There are disadvantages to using this method:

• The definition of a snipped stamp is poor in comparison with a symbol drawn in a desktop publishing (DTP) or professional graphics program. The images usually look fuzzy, especially when enlarged.
• It’s not possible to control the size of the snipped image, so the symbol may have to be resized every time it’s stamped in the margin, which wastes time.
• Snipped stamps don’t have transparent backgrounds. This can be aesthetically unpleasing when you are stamping onto tinted pages. If you’ve created a stamp that needs to be placed in-text on a PDF, the lack of transparency will cause problems because you’ll be masking content that your client won’t want to be hidden.

Using the snipping tool to create stamps is recommended if you need a quick solution and you don’t think you’ll need to use the new symbol in future jobs. If you do think you’ll use your new symbol time and time again, it might be worth considering the second method.

Second method
You can use a DTP program such as Microsoft Publisher, Adobe InDesign, and QuarkXPress, or a graphics program like CorelDraw and Adobe Illustrator. I use MS Publisher because it’s included in my MS Office bundle. I’ve also found it quite easy to use – this is partly because it’s entry-level DTP software and partly because it’s an MS product so the functionality is quite similar to that of MS Word.

Once you’ve drawn your new symbol in your DTP program, you need to save the document as a PDF. This can usually be done very simply, using the 'Save as' function. The image will then be ready for upload into your PDF editor’s stamps palette.

The disadvantage of using this method is that it requires greater investment in time in the short run. I’d only recommend it if you are creating a stamp that you think will be useful for many jobs to come.

The advantages of going down the DTP route are:

• The finish of the stamp is more professional – the images are much sharper than the snipped versions.
• You can draw multiple stamps in a single DTP document – just make sure that each image is drawn on a new page. Then you have to save one document as a PDF from which you’ll upload your new stamps.
• You can control the size of the stamp. This may take some experimentation, but once you’ve drawn one proof-correction mark that you know produces a stamp that you can universally use on PDFs without having to resize, you can use this as a template for any future stamps you create.
• You can control the transparency of the stamp. Users of my stamps files will know that some of my symbols don’t have fully transparent backgrounds. This is something I plan to rectify when I have time!

Using a DTP/graphics program is more time consuming but gives a more professional finish and is worth it if you think you’ll use the new symbol in multiple jobs.

Saving and installing your new stamps
If you have used the snipping tool to create a new GIF, JPEG, or PNG stamp, you can save it wherever you wish. I usually choose the Downloads folder. Then open your PDF editor and upload the stamp.

Installing snipped images to PDF-XChange

• Open the PDF you wish to mark up
• From Menu: Tools > Comment and Markup Tools > Show Stamps Palette
• From Stamps Palette: Click on an existing Collection or create a new one (using the New button with a small green cross); select 'From Image'
• From a browser window: Locate your image from the folder in which you saved it, e.g., Downloads, and choose 'Open'

Installing snipped images to Adobe Acrobat (v. 9)

• Open the PDF you wish to mark up
• Click on the stamp tool on the top ribbon
• Select 'Create Custom Stamp'
• From browser window: Locate your image from the folder in which you saved it, e.g., Downloads. Note that in Acrobat you will need to choose the relevant file type in order for your symbol to show up. So if you saved your snipped image as a PNG, you’ll need to select this from the drop-down menu under file type; 'Select'; 'OK'
• You can now name your stamp and assign it to a Category (you can use an existing Category or create a new one, e.g., Proofreading)

Installing snipped images to Adobe Reader (v. XI)
I haven’t found a way to import snipped stamps into Reader; the only option is to upload stamps that have been saved as a PDF, which isn’t possible with the Windows snipping tool at least. Given that PDF-XChange is still a very affordable editor, with outstanding functionality, I’d recommend trying it as an alternative to the free Adobe Reader and the rather more expensive Acrobat Professional.

​Saving and installing DTP-created images
If you have used DTP software and saved your stamps in PDF format, you may need to save into a specific folder. The installation process is a little more complicated and will depend on the PDF editor you are using. If you are using PDF-XChange, Adobe Acrobat Professional, or Adobe Reader, carefully read the installation instructions I’ve provided on The Editing Blog.

In this article, I provide an overview of PDF proofreading mark-up using the stamping tool.

When I first started my business, I was strictly a proofreader and most of my work was on paper.

Back in 2006, I was working primarily for publishers. These clients often wanted me to proofread against copy rather than blind. That meant that I was receiving large packages through the mail containing not only the final page proofs but also the galley proofs.

Postage costs were huge, though my clients bore the cost; but I still had to factor in the time I spent either waiting for couriers or hopping into my car and driving to the post office so that I could return the galleys and marked-up proofs.

These days, things are different. Most publishers have embraced digital mark-up. I'm still required to work on final page proofs, and the clients still like me to annotate using UK-industry-standard mark-up language, but I can do it all onscreen – using my PDF editor’s commenting and mark-up tools – and the stamping tool.

This saves the publisher money by eliminating postage costs and removing the need to print hundreds of pages of hard copy. It also saves me time, and, for those of us in the business of editorial freelancing, time is money.

Most editorial professionals have already embraced digital mark-up (either on PDF or in Word). Little of what follows may be news to them. Even though this article is aimed at the novice who's in the process of investigating digital workflows and the tools available to assist them, experienced professionals, and professionals seeking to expand into proofreading, are likely to find the information valuable.

Two caveats
First, I’m based in the UK. If you’re from elsewhere, you might not recognize some of the symbols shown in this post. That’s not because the symbols are wrong, but because there are differences in mark-up language between countries.

The British Standards Institution has issued the BS 5261C:2005 ‘Marks for Copy Preparation and Proof Correction’ (readers can buy a hard-copy list of these marks from the Chartered Institute of Editing and Proofreading (CIEP) and that’s what my publisher clients expect to see. Your clients might have different expectations.
​
Second, stamping tools can be used in a number of different PDF editors. My own preference is PDF-XChange (from Tracker Software). Some of my colleagues prefer Tracker’s PDF Editor. Others, still, use Adobe Acrobat Professional or Adobe Reader.

​If you’re not sure what suits you best, take advantage of the various free trials on offer.

For demonstration purposes, some of the screenshots in this essay are based on working in PDF-XChange. However, the underlying principles are the same.

What are proofreading stamps?
Proofreading stamps are simply digital versions of the symbols you would draw by hand on a paper proof. Below is a screenshot of some of the BS 5261C:2005 symbols that UK proofreaders use.

The screenshot above shows a partial view of the PDF-XChange stamps palette. I’ve chosen to number the symbols, rather than naming them, because this allows me to change the order easily (see Onscreen proofreading tips: Reorganizing your stamps palette in PDF-XChange).

Each symbol in a palette can be selected and then stamped onto a PDF using the relevant tool, usually accessed through the PDF editor’s comment-and-mark-up toolbar.
​
Below, the stamping tool in PDF-XChange is circled:

Here’s what it looks like in Adobe Reader:

And, finally, below is a screenshot from Adobe Acrobat 9:

​The answer is not actually as straightforward as one might hope! As far as I’m aware, my Irish and Australian colleagues find the BS 5261C:2005 symbols acceptable (feel free to correct me if I’m mistaken); in the UK, these BSI marks are absolutely considered standard.

​However, my Canadian colleague Adrienne Montgomerie, in her essay ‘The Secret Code of Proofreaders‘ (Copyediting, October 15, 2014), points out that for editorial professionals in parts of North America ‘[t]he challenge is always whether or not the designer will understand the marks. It’s hard to say that there are standard marks.’

She goes on to illustrate the differences between the Canadian Translation Bureau’s Canadian Style guide marks and the marks preferred by the Chicago Manual of Style.

The best advice I can give to novices is that they check with their national editorial society and their clients before embarking on this type of work.

Why use mark-up language on digital proofs?
Using stamps isn’t the only way to mark up a PDF, of course. Some of my colleagues’ clients prefer sole use of the commenting and mark-up tools embedded in their PDF editors.

When I use the stamping tool, it’s because my client wants to see all the suggested corrections in the page-proof margin (just like with a hard-copy proofread) rather than in pop-ups (see the example later in this article under ‘What does a stamped PDF proof look like?’). Ask your client what they prefer.

In ‘Are proof-correction marks redundant? Not even close!' – an introductory guide to using proofreading mark-up symbols – I consider the issue of why these little hieroglyphics are useful. If you’re new to proofreading, you might like to read the article in full. For the purposes of this article, the key points can be summarized as follows:
​

• If your client wants all the annotation in the margins of the page proofs, there’s very little room in which to work. Specialized mark-up language, even when working digitally, is an efficient way to tell the typesetter/designer what to do.
• The ability to use professional mark-up language, when required to do so by a client, demonstrates professionalism. Some editorial societies’ codes of practice demand knowledge of standard mark-up language. See, e.g., The Australian standards for editing practice, 2nd ed. (2013); Chartered Institute of Editing and Proofreading (CIEP) Code of practice; and Editors Canada’s Professional Editorial Standards: ‘E. Standards for Proofreading‘
• Stamping a symbol on a PDF, or drawing a symbol on paper, is quicker than writing out an instruction. Being able to mark up in this way can therefore increase efficiency and productivity. If you’re working for fixed fees, it’s a timesaver and money-earner.
• If you don’t understand how to mark up using this specialist language, you’re marketable to fewer clients. It therefore makes good business sense to acquire the skills to mark up in this manner, both on paper and digitally.

Where can I find digital stamps?
If you want to use the BS 5261C:2005 proof-correction marks to annotate a PDF, you can find everything you need on this site in the Stamps archive. In particular, Roundup: PDF Proofreading Stamps (quick-access links) provides the access links to a full set of downloadable PDF proofreading stamps and the installation instructions.

U.S. stamps files are available via the Copyediting-L site, under the Resources tab. Scroll down to ‘Diana Stirling’s (2008) editing marks for PDF documents (Zip documents)’.

Finally, search the Editing Tools section of Katharine O’Moore-Klopf’s Copyeditors’ Knowledge Base using the key words ‘PDF Editing Stamps.’ This will bring up a number of useful resources that you might prefer to try.

Where can I learn onscreen mark-up?
If you’re already familiar with standard proof-correction marks, and have used them extensively on paper-based projects, you might well be able to teach yourself to mark up onscreen with stamps. That’s how I went about building my digital mark-up skillset.

However, if you’re a novice or lack confidence, you might prefer more formal training that introduces you to using proof-correction language correctly and clearly (whether on paper or digitally).
​
In the UK, the Chartered Institute of Editing and Proofreading (CIEP) and The Publishing Training Centre, to give just two examples, include onscreen mark-up as part of their distance-learning proofreading training.

Adrienne Montgomerie runs a webinar called Editing PDF Files via Copyediting. You can buy the four-step session here.
​
There is also some good, and free, online guidance on the Right Angels and Polo Bears blog under the Acrobat PDF archive. See also the Stamps and Working Onscreen archives on this blog.

What does a stamped PDF proof look like?
A PDF that’s been marked up using proof-correction stamps looks just like its paper cousin – the only difference is that it’s in a file on your computer rather than in a pile on your desk.

​As you can see from the sample below, you can, of course, use the onboard tools. Here, I’ve added in a query for the author (using the Commenting function); if, however, my client had wanted all annotation to be viewable in the margins, I’d have created a separate query sheet to communicate my concern with the highlighted spelling issue.

Summing up
Proof-correction marks are not a thing of the past — far from it. Whether you are working on paper or onscreen, being able to offer this method of annotating a proof is a valuable business asset. It gives both you and your clients choices.

There will be times when a client will prefer you to work on paper, or directly in Word. And there will be times when you work with clients who don’t know the meaning of proof-correction symbols, and will ask you instead to use a PDF editor’s onboard commenting and markup tools.

​However, if you are going to be working with clients who want a traditional margin-based proofreading service (where all your annotations are made on the typeset page) but in a digital format, the ability to mark up using proofreading stamps will serve you well.

In this post I show you how to reorganize the display of your digital proofreading stamps in PDF-XChange so you can improve the efficiency with which you work.

The free digital stamps files I’ve provided here on The Editing Blog contain over 70 individual images, all based on the British Standards Institution’s “Marks for copy preparation and proof correction” (BS 5261C:2005).

​The issue for many newbies is that the palette can appear cumbersome – we all work in different ways, and the symbols that we most often use may not be positioned in the most convenient place for our particular needs.

Having the full palette open on the screen takes up a lot of space, even if, like me, you use multiple screens. I prefer to have my palette near the text because it’s quicker to access, thus increasing my efficiency:

Decreasing the size of the palette is one option, and allows placement on the screen that won’t interfere with the text. However, this requires using the scroll bar on the palette in order to access the stamps located further down the palette, reducing efficiency further because not all the stamps are on display.

Reorganizing the stamps for your own needs 
When I created the original stamps files, I ordered them according to what my specific needs were at that time. But my preferences have changed since 2012, and it’s not unusual for my current preferences to change on a job-by-job or client-by-client basis.

For example, one particular client for whom I work provides me with PDFs that frequently require the use of the Turn over character(s)/word(s)/line(s) symbol. This symbol is located near the end of the downloadable stamps files. This meant that when I first opened up the palette in XChange it appeared as follows (see highlighted area at the bottom of the image below):

The solution is to move the frequently used symbol to the top of the palette for this particular client work. This is most simply done by renaming the stamp in a way that forces it into the required position. My preference is to name most of my stamps with numbers rather than descriptive names (see image above and compare the often-used Delete symbol (named 1) with the rarely used Change to small caps mark (named 9.83).

The beauty of renaming with numbers is that you have the freedom to move any stamp anywhere at any time. You can change the positions as and when you wish. For demonstration purposes, I’ve chosen to move the right-hand margin Turn over symbol to the top of the palette and place it next to the Delete symbol.

The process is quick and simple:

1) Left-click on the symbol you want to move. The area below the mark, where the symbol's name is located, will appear with an orange tint.

2) Move your mouse to the top of the palette and left-click on the “Rename” tab. A window will appear, housing the stamp’s current name.

3) Type in a new numbered name that will force the stamp into the numerically ordered position you desire. In this case, I want the Turn over symbol to appear next to the Delete symbol. Delete is named “1”; the stamp to the left is named “0.52”. Choosing any number between 0.52 and 1 for Turn over will therefore ensure preferred placement. I decide to rename Turn over as “0.99”. I type in the number and select “OK”.

4) Note that the stamp has been renamed but it still hasn’t moved into its new position.

In order to force the repositioning, I need to move out of the currently displayed palette and then reopen it. This can be done in two ways. Either close the palette completely by clicking on the X in the top-right-hand corner of the window (then reopen via the menu: Tools>Comment And Markup Tools>Show Stamps Palette) …

… or switch to a different Collection and then move back into the original Collection in which you renamed your stamp. The Collections can be found on the left-hand sidebar of the XChange palette, and you can move this sidebar in and out of view by clicking on and dragging the thick grey line, as highlighted below.

5) When you reopen the palette and click on the appropriate Collection, you’ll see your renamed stamp positioned exactly where you want it. To move the Collections sidebar out of view, simply click and drag on the grey line. This will provide more space in which to display all your proofreading symbols.

Marginal gains for increased efficiency
If renaming stamps seems like a lot of effort for little reward, remember that marginal gains count for a lot with editorial work. This is why tools such as macros, shortcuts and find/replace are useful. The same applies to creating an efficient stamps palette.

Every second you spend scrolling to find the stamp you want adds up. Seconds become minutes, and minutes become hours. If you’re being paid per hour, and your client doesn’t have a top-line budget, it may not matter how long it takes you to do a job, nor that you’re working inefficiently.

However, many clients do have a top line, and many editorial professionals are working for fixed fees. Efficiency matters. Furthermore, some of us need to attend to the way in which we use our hands, wrists and arms repetitively when working onscreen.

Organizing a stamps palette in a way that is memorable to you, and enables the fastest possible access, speeds up the onscreen markup process and reduces physical strain.

If you haven’t got round to renaming your stamps numerically, try it and see whether it makes a difference.

This roundup provides quick access to all the PDF proofreading markup articles posted on The Editing Blog.

​I should have done this ages ago so apologies to anyone who's had to spend unnecessary time navigating their way around the Stamps archive to see what's available.

I'll keep this updated as new files are added so that there's always one central resource with all the necessary links.

• IMPORTANT: For detailed installation instructions, see my article Installation Instructions for Proofreading Stamps. Please follow these instructions to the letter BEFORE contacting me for support. 
• If you wish to create your own stamps, or you want to see samples of what a marked-up PDF looks like, see my article PDF Editing – Making the Most of the Stamps Tool. 
• For a list of American proofreading stamps visit KOK Edit’s Copyeditors' Knowledge Base and scroll down to "PDF editing stamps".
• For some great PDF mark-up tutorials and tips (using Acrobat), take a look at the Acrobat PDF archive on the Right Angels and Polo Bears blog curated by Adrienne Montgomerie.
• You can find more information about onscreen work in the archives here on The Editing Blog: Stamps archive and Onscreen Work archive.

If you’re proofreading onscreen, either with my proofreading stamps or your software’s comment and mark-up tools, it’s worth spending a few minutes to set up the various onscreen elements in an ergonomic fashion as well as familiarizing yourself with basic keyboard shortcuts.

Some aspects of onscreen work are speedier – searching for and implementing global changes, for example – while moving between the various mark-up tools is not as quick as using a hand and pen. There are, however, things you can do to compensate and make your onscreen experience more effective.

​1. Make the toolbar work for you
Shift the most-used elements on your toolbar so that they are near to each other and on the side of the screen with which you operate your mouse. These elements might include the typewriter, mark-up tools, text tools, and stamp and save buttons. Use your mouse to click, hold and drag the elements across the toolbar ribbon.

2. Use the stamps palette
Use stamps of proofreading symbols to complement the comment box and mark-up tools in your PDF editor. You can create your own or use the sets I’ve already developed. They’re available free of charge here. If you’re unfamiliar with these, see PDF Editing: Making the Most of the Stamps Tool.

Remember to keep your stamps palette open; it will save you time when selecting each stamp you want to use.

In XChange you can minimize the size of the symbols as they appear in the palette (see the highlight in the screenshot to the left). This enables you to see a greater number of stamps while you are working without having to scroll up and down the palette. In Acrobat, the palette is not as user-friendly, so use a second screen to get the best of the display.

In XChange, number similar stamps sequentially so that they appear in a logical order. This will make it easier to find the stamp you need, particularly if each palette contains a lot of symbols (If you’ve downloaded my XChange stamps simply change the number-name in order to re-sequence them).

It's useful to keep your palettes of different-coloured stamps separate so that the palettes don't become overly cluttered. Again, this will enable you to locate the stamp you need more efficiently. 

3. Hook up a second screen
I generally use a laptop, but I hook up my old desktop screen to enable me to use two screens at once when I’m doing onscreen work. This works well on three counts: 

1. The desktop screen is larger, so it’s much more comfortable to work on. I can enlarge the PDF view to 150%, which displays most of the page on the screen while presenting the text in a size that’s easy on the eye. 
2. A larger screen means you can expand your stamps palette in a way that will maximize the number of stamps on show without interfering with your PDF page. 
3. It’s inconvenient and time-consuming when you want to write a query to the client only to have the comment box open up under another element, which then has to be moved. To avoid this, you can slide elements such as the Search window and Comments List over to the smaller screen so that they are visible and usable at all times, but not taking up the grey space where the comment boxes appear.

​4. Utilize basic keyboard shortcuts
These are my preferred keyboard shortcuts when working with PDFs. There are many, many more but I like these because all but one can be managed easily with one hand.

Alt Tab: this is one of my most-used keyboard short cuts and is especially useful if you only have one screen to work on and need to flit between different programs or files.  
Ctrl S: save
Ctrl C: copy
Ctrl X: cut
Ctrl V: paste
Ctrl Z: undo
Ctrl A: select all
Ctrl Shift F: opens search window

5. Bookmark key pages
If you refer back to the same key pages time and again and your client hasn’t already bookmarked these (contents, part titles, chapter first page, bibliography, index etc.), it’s easy to do it yourself and will save you time. Use Ctrl B to open the bookmark function in Acrobat, PDF-XChange or PDF-XChange Viewer and name your page.
​
​​6. Use a snipping tool to make your own quickie stamps
If you are constantly using a particular combination of mark-up symbols in a piece of work (e.g. you have to change A to Å many times), you can make your own quickie stamp using a snipping tool. Windows supplies this, but if your operating system doesn’t there are plenty of free alternatives online. Pin it to the task bar at the bottom of your screen to access it quickly.

In the case given above, you would use the typewriter to print Å on your PDF, followed by the replace-slash stamp. Use your snipping tool to draw round both marks and save. Then import your new stamp into your palette. Now you only have to make one click, not two, in order to make the margin mark.

Anything to share?
Do you have any tips to share for more efficient onscreen work, such as favourite keyboard shortcuts or using function keys? Please share them with us in the Comments section below so that we can all improve our onscreen working experience.

If you don't have the full paid-for versions of, say, Adobe Acrobat or PDF-XChange, you can still use my proofreading stamps. At a recent local SfEP chapter workshop, my colleague Sara Peacock demonstrated the stamps. She says: 

"The stamps work with [the free] Adobe Reader, but the proofreader will need to ensure that whoever creates the PDF 'enables comments' before sending it, otherwise the comment tools that are needed (as well as the stamps, the pencil tool, the strikeout tool, and so on) won't be accessible.

"However, all of these tools (or their equivalents) are available in the free PDF-XChange viewer, in which the stamps can also be used. (Personally, I find it a more stable piece of software than the Adobe version so I use it all the time anyway. It's a bonus that I don't need to insist on enabled PDFs.)"

I normally work in the full version of Acrobat Standard, but following Sara's comments I decided to give XChange Viewer a try. I must say, it was a doddle and the functionality is exceptional given that this won't cost you anything. The stamps palette is much clearer, for one thing, and uploading the stamps is quicker, too. I'd recommend giving Viewer a try, even if you're a die-hard Acrobat user! Even better, XChange Viewer allows you to upload them all in one go!

Click on the buttons below to download the PDFs files containing the stamps, then head over to the installation instructions. 

UPDATE 5 JUNE 2020. All the stamps now have transparent backgrounds, which means they can be placed on top of greyscale and colour pages and boxes, and squeezed between text without blocking out the elements.

This article contains installation instructions for most versions of Acrobat and PDF-XChange. Scroll down the page to find the set appropriate for the platform you're working with. 

NOTE: Rest assured that you don't need advanced technical knowledge to install the stamps. In fact, you don't need any technical knowledge at all! You simply need to be able to follow the instructions as they are given. 

Instructions correct as of 4 January 2020 and apply to Windows 10, Office 365

1. Download the stamps collection (red, blue and black are available) and save anywhere you like. 
2. Open PDF-Xchange Editor.
3. Type “stamp” into the search box at the top of the screen and select STAMPS PALETTE from the drop-down menu.
4. Select ADD NEW.
5. Select ADD NEW STAMP FROM FILE. This will open up a new window.
6. Now select the PDF of the stamps collection you just downloaded (e.g. red).

4. Go into Tools > Comment and Markup Tools > Stamp Tool > Stamps Palette.
5. Click on the 'Add New Stamp from File' icon, which looks like an open folder.
6. Click on the folder icon to the right of the 'Name' field and select a stamp folder from your documents folder.
7. Click on 'All pages'.
8. Give the stamps a title in ‘New title’ (I think this is where you could select a page at a time and re-name each stamp with numbers).
9. Click the 'Add New' button at bottom right, and give the new collection a name (e.g. 'Red Proofreading Stamps').
10. Click OK.
11. Your stamps should install. Repeat from Step 3 for the rest of the collection.

​My colleague Steve Hammatt has kindly provided the following installation instructions for use with Editor 3.0:

1. Go into Tools > Comment and Markup Tools > Stamps Palette.
2. Click on the 'Add New Stamp from File' icon, which looks like an open folder.
3. Click on the folder icon to the right of the 'Name' field and select any PDF from your computer.
4. Click the 'Add New' button at bottom right, and give the new collection a name (e.g. 'Red Proofreading Stamps'). Doing this will have automatically created the folder you will need. In Windows XP this should be: C:\Documents and Settings\<user>\Application Data\Tracker Software\PDFXEditor\3.0\Stamps. In Windows 8, 7 and Vista it should be: C:\Users\<user>\AppData\Roaming\Tracker Software\PDFXEditor\3.0\Stamps.
5. Navigate to that folder; delete the file to leave the folder empty.
6. a) Open Roundup: PDF Proofreading Stamps (quick-access links). b) Scroll through and click on, and open, the version of the XChange stamps file you want. (Don't worry if you can only see one stamp on the front page. This is as it should be.) Save the downloaded file in the folder you have just created.  
7. Close Editor and re-open it. You should see a full set of stamps available for use in the Stamps Palette.
8. For each separate file you choose (different colour options or additional sets of stamps) you will need to repeat Step 6b.

​One of the main benefits of using PDF-XChange Viewer is that you can import all my stamps in one go. Video tutorial. For those of you who'd like to watch a tutorial of the steps outlined below, here's a video demonstration in which I talk you through the process, step by step, while actually downloading a set of stamps onto my own computer.

NB: This is the squeaky-chair edit, a limited-edition version created especially to provide the feel-good factor for editorial freelancers whose home offices benefit from well-oiled swivel-seating arrangements!

 Written instructions 

1. Download PDF-XChange and install it on your computer.
2. Create a special folder for your stamps. To do this:
   a) Open PDF-XChange, select Tools from the top menu, then Comment And Markup Tools, then Show Stamps Palette.
   b) Click on 'New ...' to create a New Collection.
   c) Then click on 'From PDF ...' and use this to copy any PDF you like from anywhere you like in your computer.
   You should now see a New Collection with that PDF in it. Doing this will have automatically created the folder you will need. In Windows XP this should be: C:\Documents and Settings\<user>\Application Data\Tracker Software\PDF- XChange Viewer\2.0\Stamps. In Windows 10, 8, 7 and Vista it should be: C:\Users\<user>\AppData\Roaming\Tracker Software\PDF-XChange  Viewer\2.0\Stamps.
3. Navigate to that folder,* select the copied PDF (it will have a weird number – don't worry) and delete it, leaving the folder empty. 
4. a) Open Roundup: PDF Proofreading Stamps (quick-access links).
   b) Scroll through and click on, and open, the version of the XChange stamps file you want. (Don't worry if you can only see one stamp on the front page. This is as it should be.) Save the downloaded file in the folder you have just created.  
5. Close PDF-XChange and re-open it. You should see a full set of stamps available for use in the Stamps Palette.
6. For each separate file you choose (different colour options or additional sets of stamps) you will need to repeat Step 4b.

* Can't find the AppData folder?
If you can't find the folder, the most likely reason is that the Application Data (or AppData) folder (a hidden folder) is invisible on your computer. 

• To show it in Windows XP, go to Start, Control Panel, Folder Options, View, Show Hidden files and folders. 
• For Windows 7 and Vista, go to the Windows icon in the bottom left-hand corner of your screen and search for 'show hidden files and folders'. Click on this and look down for the Hidden Files and Folders icon. Then check the button labelled 'Show hidden files, folders and drives'. Select OK. Now you should be able to save the XChange files in the correct place, enabling them to appear in the palette.
• For Windows 8, follow the instructions in this tutorial from bleepingcomputer.com: How to see hidden files in Windows 8.

1. Open any PDF.
2. Select the stamp icon from the Comment and Markup Toolbar (this ribbon should show up at the top of the page) and click on the drop-down menu.
3. Select Create Custom Stamp.
4. Click on the Browse button and select the location of the PDF stamps file (e.g. Red Stamps).
5. Each stamp will appear on a separate page. Use the scroll bar to select the stamp you wish to upload.   
6. Click Import.
7. Click OK.

The first time you do this you’ll have to write in a category (e.g. Red Stamps). When you import a second stamp you can simply select this option. You can also name the stamp if you wish but I didn’t bother, choosing instead to leave the default New Stamp.

When you have uploaded all your stamps and are ready to start marking up your document, select Show Stamps Palette from the stamp icon in the ribbon menu and a box will appear. If you have different categories (e.g. Blue Stamps) you can select these from here.

1. Open any PDF (If the stamp icon isn't on display in the toolbar select the Commenting Toolbar by choosing View, Toolbars, Commenting from the menu).
2. Go to the stamp icon on the top ribbon menu and click on the drop-down menu.
3. Select Create Custom Stamp.
4. Click on the Select button and then the Browse button to select the location of the PDF stamps file (e.g. Red Stamps). 
5. Each stamp should appear on a separate page. Use the scroll bar to select the stamp you wish to create.
6. Click OK.

The first time you do this you’ll have to type in a category (e.g. Red Stamps). When you import a second stamp you can simply select this option. You can also name the stamp.

When you have downloaded all your stamps and are ready to start marking up your document, select the drop-down menu from the stamp icon in the ribbon menu, and the categories you have created will be listed along with the defaults. You can then select the stamp from the category you require.

​My colleague Jenny Macgregor has very kindly put together some instructions for downloading my proofreading stamps into Acrobat X. Here's her advice...

1. Download the stamps from this website, whichever colours you use, and save somewhere convenient. At this point I recommend making a list on paper of the number of each stamp, and what it is (it varies between colours). This is worth the few minutes it takes, and is invaluable later on in the process.
2. Open the PDF you are proofreading. In the bar across the top, click on Comment, as you would normally do to start marking up, then open Annotations, if it is not already open.
3. Click on the stamp icon (it takes a few seconds for a grey box to open), then click on Custom Stamps and, from the box which pops up next to it, Create Custom Stamps.
4. The Select Image for Custom Stamp window will open with a browse facility. Use that to find the stamps you have saved earlier, starting with whichever colour you are likely to use most.
5. At this stage you will need the paper you have marked all the symbols on: use it to choose which you are most likely to need, and then use the number and the slider on the right-hand side of the box to locate the first symbol you want to install. You need the number because the images in the box are too small to distinguish easily. Click OK.
6. A new box opens; in the category box, type in the colour, i.e. red stamps/black stamps/blue stamps. I haven’t found any benefit in giving a name to each stamp, so just leave it as New Stamp. Then click OK. The box disappears.
7. Repeat this with any other symbols you are certain to need, and any other colours. After the first one in each category, the category name (red stamps, etc.)  appears in a drop-down box to be selected, which saves time.
8. Once you start the proofread, if you want to add a stamp to the PDF, click on the stamp symbol, and the grey box opens as before, but now it will have the categories of stamps you have installed, i.e. red stamps, black stamps, etc. Click on the colour you want to use and another grey box will open with the symbols in it. Click on the symbol you want to use, and it will ‘ghost’ onto the PDF you are proofing. Move it to where you want it and then click, which will attach it to the PDF. That’s it!
9. The last stamp you used can be added to/removed from a favourites list – favourites appear in the first grey box to open, and can be selected from it, which saves some time.
10. At any time during the proofread, if you find you need a stamp you haven’t already installed, repeat steps 3–6, using your paper list to find the appropriate stamp number.
11. To keep the stamps palette open, click on the stamp symbol, and when the grey box opens click on Show Stamps Palette.

Instructions correct as of 5 December 2021

1. Open any PDF.
2. Click on the Tools tab in the ribbon.
3. Click on the Stamps icon. The Custom Stamps icon will now appear in the ribbon.
4. Select Create from the Custom Stamps drop-down menu.
5. Click on the Browse button to select the location of the PDF stamps file (e.g. Red Stamps). 
6. Each stamp should appear on a separate page. Use the scroll bar to select the stamp you wish to create.
7. Fill in the Category (e.g. Red stamps). You can re-use this for the second stamp you add.
8. Give the stamp a name (e.g. '1' or 'delete').
9. Click on OK.
10. Use the Stamps Palette icon in the ribbon to access your symbols (remember to select the relevant category).

Here are a few tips to bear in mind when using stamps. Search the Stamps archive for other useful articles and resources.

• Remember to keep your stamps palette open when you are working in both Acrobat or XChange; it will save you time when selecting each stamp you want to use.
  
• In XChange you can minimize the size of the symbols as they appear in the palette. This enables you to see a greater number of stamps while you are working without having to scroll up and down the palette (see the highlighted circle on the screenshot below).
• In XChange, number similar stamps sequentially so that they appear in a logical order. This will make it easier to find the stamp you need, particularly if each palette contains a lot of symbols (see screenshot below).
• It's useful to keep your palettes of different-coloured stamps separate so that the palettes don't become overly cluttered. Again, this will enable you to locate the stamp you need more efficiently. 

Tips for proofreading PDFs
These days, it's not uncommon to be asked to edit and proofread onscreen. If you're editing in Word, all well and good; you can amend the text directly. If you're tackling designed page proofs, you'll probably be working on a PDF. 

The PDF editor's onboard markup tool is one option. Using custom stamps is another, and that's what I'll be exploring today.

​Why use customized stamps?
Even in the standard versions of most PDF editors (as opposed to their freely available readers), the tools can be restrictive. For me, punctuation errors are a major problem – I feel that insertion and deletion tools for punctuation marks (and even single letters) are often ambiguous, with the highlight or strike-out line appearing to ‘spread’ further on the page than would be the case on a paper mark-up.

About the stamps …
I created a set of customized stamps that can be imported into my PDF editing software (I have both PDF-XChange and Acrobat).

The stamps are based on the current BSI proofreading symbols and once downloaded can be imprinted onto the page, giving the proof the appearance of its paper cousin.

No more clunky comments and digital sticky notes, and say goodbye to ambiguous highlighting. Now you can keep the comment boxes in reserve for queries to your author or in-house editor.

​The following is a sample of just a few of my stamps.

Which software is compatible?
I’ve tested the stamps on Adobe Acrobat (standard version) and PDF-XChange and can confirm that they can be imported (other PDF editors that have stamping functions, such as Foxit and PDFill, may also be compatible, though I’ve yet to verify this – comments welcome!).

What if you only have a free reader/viewer?
No problem – you don't need to have the full paid-for versions of Acrobat or XChange in order to use the stamps.

You can use your free Acrobat Reader as long as you ask the person who has created the PDF to 'enable comments'.

With PDF XChange Viewer, you don't even need to worry about enabling comments – the stamps will work on your PDF as soon as you have uploaded them. An additional benefit of Viewer is that you can import all the stamps in one go.

Can you use the stamps with a Mac?
One of the first questions asked after I posted this article was whether the stamps files would work for Mac users.

I work on a PC but since the stamps files are PDFs it doesn't make any difference whether you're working on a PC or a Mac. Rather, the most important thing is that you have the Mac version of your PDF editor, e.g. Acrobat for Mac.

What does the marked-up proof look like?
I’ve been delighted with the results, as have many of my clients. The marked-up proofs using the stamps are much clearer to read, as the two examples show.

There are only four amendments in Example 1, the comment-box version. Imagine how much time it would have taken to select the text, choose the relevant option from the Text Edits menu and write the instruction to the typesetter if all the amendments in Example 2 had been made without using stamps.

​And if the typesetter opened up all these comments boxes, what a mess it would have been.

Creating stamps
Creating the stamps is the fiddly part and the most time-consuming.

Getting the correct size, so that you don’t have to resize each stamp when you’re working on a set of proofs, takes a little time and, of course, creating each individual stamp can seem painstaking.

However, the job only has to be done once and I’ve been using mine for a couple of years now. It’s worth spending some time playing around with your designs early on in order to make life easier for yourself later.

I’ve created stamps in red, blue and black because my clients have different requirements.

I used Publisher to create the stamps, but you could use any software with a drawing tool. Set up each stamp on a separate page. Once you’ve drawn all your stamps convert the file into a PDF.

Want to use the stamps that I've already created?
I’m happy to share with colleagues who have the same commitment as I do to improving skills and supporting our industry’s professional standards.

To access your copies of my stamps, click here – there's no charge. If you're using PDF-XChange (I'd recommend you do so), make sure you select the stamps labelled "XChange".

Note: Please note that my stamps are based on proofreading symbols as defined by BS 5261-2 (2005). If you are working outside the UK, not all of the symbols may conform to those you are used to working with.

For a set of stamps that use US proofreading marks, take a look at KOK Edit's excellent Copyeditors' Knowledge Base – scroll down to 'PDF'. 

Importing customized stamps
For installation instructions, and some useful tips, see my article Installation Instructions for Proofreading Stamps.

Future updates
Periodically, I create new or modified stamps to deal with an amendment that's cropping up frequently in a job I'm working on. I'll place these additions in the Stamps archive located on the blog sidebar. Drop by now and then to see if there's anything new that's of use to you. I'll name the post with a description of the stamp and I'll include a picture and downloadable file in case you want to add it.

Which PDF editor do you use?
Do you use customized stamps in PDF editors/readers other than Acrobat and PDF-XChange? Please let us know in the Comments section so that others can see which software is compatible.
