It may be prudent to not trust a document that generates errors for content that could not be suppressed.
For other errors, you may wish to analyze the document for non-conforming content in order to evaluate
whether you should trust the document.

8.2 Preview Mode and Validation (View Signed Version)

Acrobat and Adobe Reader store in signed documents a unique document version for every signature in
the document. In other words, they "remember" that version A is signed, that changes were made to
version B, and so on. When you open a document, the latest version is always displayed. However, it is
sometimes useful to view the signed version in order to see what content was actually signed.
To view the signed version of a document.
1. Open the Signatures pane, and verify the signature status.
2. Right click on a signature and choose View Signed Version.
View Signed Version is essentially a rollback feature that enables the signature validator to view the
document version as ut was at the point in time when it was signed.
3. Choose View Report in the Document Message Bar to view a report about the dynamic content that
could and could not be suppressed (if any).
4. Right click on the signature and choose Show Signature Properties for more detail about the signature.

8.3 PDF Signature Reports

Signature workflows often require a document that has a deterministic and repeatable visual rendering
that is consistent with the state of the document as signed. This variant does not concern itself with
content in a document that is not rendered or does not affect rendering. Examples of such content include
metadata and bookmarks.
The level of document's conformance to signing best practices is determined by the presence or absence
of certain content. There are three categories:
"Content preview mode cannot suppress" on page 128

"Content preview mode can suppress" on page 128

"No external dependencies or dynamic content" on page 129
