PDF Proofreading Marks

Digital editorial markup

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 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 or comments alone.

Case study

Nikki M Group worked with an editorial team who implemented PDF Proofreading Marks on Signpost Mathematics, a series consisting of 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.
