How to 'Flatten' in Adobe Acrobat Pro DC
We recently purchased Adobe Acrobat Pro DC and I'm trying to figure out how to take a document that I added a stamp to and flatten it so our users cannot delete the stamp from it. I have found the 'Flatten' option but it is greyed out. The only option in the menu available is 'Import as Layer'. How do I enable the 'Flatten' feature? In previous versions, I used a java script to flatten when the option was not available.
