Using the Signature Pane Comparison Method
Rather than working through the Compare Documents dialog box, use the Signatures pane command.
You do not have the same control over variables used in comparison, but it is a good method for a quick
check.
In the Signatures pane, select the signature you want to compare with the current version. Choose
Compared Signed Version to Current Version from the Options menu in the Signatures pane. A temporary
PDF file opens showing a page-by-page comparison of the document content highlighting the differences,
as shown in Figure 10.28.
