You can also use the edit log to compare two versions of your Certified PDF document. This is recommended if you know that changes have been made that are hardly visible on screen, such as overprint or trapping settings or changes in (hidden) layered objects.
The Using the Edit Log button is enabled.
The first snapshot is opened and the Enfocus Certified PDF Edit Log Navigator appears.
The document will show where the changes occurred by adding a transparent overlay to the object.
The Edit Log Navigator displays only the changes for the current page in the document. If you go to another page in your PDF document, the Edit Log Navigator adjusts the list of changes to match the new page.
