Question

Compare Documents false positive for differences

Hello, 

 

When doing a PDF compare, which is usually done by comparing an optimized PDF created from an MS Word doc and then the scanned/optimized/OCR PDF with a signature (same document), there are a significant amount of changes flagged that aren't actual changes. This is also done selecting "Compare Text Only", and with many changes in settings - Only selecting Text, Autodetect, Scanned documents, drawings, illustrations, etc. Almost all text is flagged as a change. This seems to be partially due to the text being inside of a table. We are using a current version of DC - 20.013.20074.18474. Acrobat should be able to interpret the graphics and compare the actual text values with each other. With the current funtionality, the compare function is pretty much unusable. Any help here would be appreciated.

Thanks, my workarounds are to tweak my defaults either by

  1. degrade Conversion setting to "Smallest File Size" (PDF Maker). Why did it work when exported File Size did not shrink? 
  2. split my Microsoft Office Document into partial documents (PowerPoint in my case) to resolve false positives from Charts and Pictures. After breaking into two files split by Slide that has real change, the Compare no longer report false positives.

I hope this helps your case....

Cheers

Locked. This thread has been unanswered since 2021 and @Sunny26326757tb7e posted his problem multiple times in this forum. The best is to consolidate in one thread.
