System information

Note: You cannot compare sessions in “optimized” Certified PDF documents. See Saving an
optimized Certified PDF document on page 107.
To compare sessions visually side by side
Comparing two versions of your PDF document visually is useful to see visible changes “at a
glance”. The idea is that you select two sessions and click the Compare Visually button. PitStop
Pro will then generate two snapshots showing the state of the PDF document at the end of the
respective sessions and present these snapshots side by side on screen.
1. Choose Certified PDF > Show History.
2. Select two sessions from the session list.
The Visually (side-by-side) button is enabled.
3. Click Visually (side-by-side).
PitStop Pro compares the two versions and displays them next to each other on screen, indicating
the differences.
To compare sessions using the edit log
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.
1. Choose Certified PDF > Show History .
2. Select two session from the session list.
The Using the Edit Log button is enabled.
3. Click Using the Edit Log.
The first snapshot is opened and the Enfocus Certified PDF Edit Log Navigator appears.
4. Select one of the changes in the list.
The document will show where the changes occurred by adding a transparent overlay to the
object.
