PDF editing in a Certified PDF workflow

To help reduce document consistency problems, the Certified PDF workflow features a mechanism that:

Based on this information, an edit log —a human readable PDF report— can be gener­ated.

If consistency between the PDF document and the source file(s) is very important, you can use the edit log to change the source file(s) accordingly. To assist in this process, a Certified PDF document can also keep a reference to the source file(s) from which the PDF document was created. You can use this reference to make sure that the source file has not been edited since the PDF document was created.
