You can add references in your Certified PDF document to one or more source files on which the PDF file was based. This does not only offer you or the PDF recipient a convenient way to find the respective source files, it also enables you to check whether these source files have changed since the time at which the Certified PDF workflow was started for this PDF document. Indeed, if you wish to “synchronize” the source file with the edited PDF document, you will use the edit log report to apply the changes from the PDF document in the source document. It is then crucial to know that you are working in the correct version of the source file.
In the top right corner of the Preflight category, the status is shown of the Preflight only (without the other Certified PDF aspects such as Original Documents and Preflight Profile Comparison).
