PDF Proofreading Marks

Digital editorial mark-up

PDF Proofreading Marks allow you to use traditional editorial marks in a digital workflow.

PDF Proofreading Marks are a great complement to annotations/comments in Adobe Acrobat. All proofreading marks show up in the ‘Comments List’ and can be checked off when taken in, as shown below.

Proofreading marks can be checked off when taken in.

The benefit of using PDF Proofreading Marks is that you can quickly visualise changes, which you can’t do with annotations/comments alone.

Case study

Nikki M Group worked with an editorial team who implemented PDF Proofreading Marks on Signpost Mathematics, a series consisting 18 titles. The entire production process was electronic with all corrections marked up in PDF files. This process saved paper, printing costs, delivery expenses and time.


The following steps will load PDF Proofreading Marks into Adobe Acrobat.

Quit Acrobat if it is open.
Download and place the file pdf-proofreading-marks.pdf in your Acrobat ‘Stamps’ folder.
Note: The location of the ‘Stamps’ folder will vary depending on your Acrobat version and operating system. For example:
Mac OS X
/Users/USERNAME/Library/Application Support/Adobe/Acrobat/DC/Stamps
The ‘Library’ folder can also be found using the ‘Finder’ menu ‘Go > Go to Folder…’ and entering ‘~/Library’.
Windows 10
C:\Users\USERNAME\AppData\Roaming \Adobe\Acrobat\DC\Stamps
If the ‘AppData’ folder isn‘t visible, go to the ‘View’ menu in ‘File Explorer’ and make sure the ‘Hidden items’ option is ticked.
Restart Acrobat
PDF Proofreading Marks will be available in the ‘Stamps Palette’. See ‘How does it work?’ on the right.
