#121: Signing a Document
Make It Valid—and Quick
If your work includes a lot of signature validation, it can be time-consuming
to choose commands repeatedly to validate a signature or signatures in each
document you open. Instead, set a preference to have signatures validated
automatically when the document opens. Choose Edit > Preferences (Acrobat >
Preferences) and click the Security category in the list. Click the “Verify signa
-
tures when the document is opened” check box at the top of the dialog and click
OK. Next time you open a document that contains signatures, they are verified
automatically.
Preview Before
Signing
Acrobat offers a Preview
Document mode, where
you can see what items
(if any) may compromise
the document’s security,
such as 3D models, lay-
ers, or Flash video. Choose
Edit > Preferences (Acrobat
> Preferences) and select
Security. Click the Select
View Documents in Preview
Document Mode When
Signing check box and
click OK.
When you click a signa-
ture field, the Document
Message Bar opens and
describes the status. Click
View Report to show a list
of items that can affect the
status, then click Close to
dismiss the dialog. Click Sign
Document to proceed with
signing.
If you work with a lot of
dynamic content and
signatures, the Preview
Document mode likely won’t
explain anything you don’t
already know, and simply
adds extra mouse clicks.
