When I OCR two versions of the same document and then compare the documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago, and the response I received had to do with the quality of the OCR and the scans of the documents. However, if I use Acrobat Pro XI to save the same documents in Word and then run a comparison in Word all of the changes are marked. When a PDF is saved as a Word document in Acrobat Pro XI, is a different OCR module being used than the one used in Acrobat Pro XI for text recognition?
