How to use PDF proofreading stamps on colour and greyscale pages

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.
