Use Compare mode in the Proof Viewer to review two proof versions side by side or as an overlay. You can confirm that the markup and comments from earlier versions have been incorporated before adding comments or making a decision.
 

Available on: Free Standard Pro Enterprise

You can only compare versions of a proof that you have access to.

Review versions side by side

Side by side view shows your proof version in separate windows. You can show or hide the comments. You can set which side shows the newest version in Proof Viewer settings by choosing it from the Version drop-down list.

 

Use zoom, pan, and navigation tools as you would in normal viewing.

Keep versions synchronized () or unlock them to scroll separately.

Highlight differences between versions (Auto Compare)

The highlights always appear on the most recent version.
