Numerous questions come up about dynamic stamps on AcrobatUsers.com – everything from what they are to how to build your own. Unfortunately there is precious little information on the subject, and what there is needs stitching together. So, I’ll take a moment to pull the pieces together by first discussing what a dynamic stamp is, how to create your own or modify an existing one, then finally how to prompt the user for information to display inside a custom dynamic stamp.
A dynamic stamp is simply any image or graphic that displays your name, date, and time on the stamp. It’s considered dynamic because the exact date and time that you apply the stamp is displayed every time you use it. Dynamic stamps obtain information from your system for the time and date, and from the Identity panel of the Preferences dialog box for your name. You need Acrobat to create a dynamic stamp but once it has been created it can be used in either Acrobat or Adobe Reader (version XI only). Dynamic stamps are located in the Comment pane under the Annotations panel in either Acrobat or Adobe Reader XI.
Then, if you still find yourself searching for answers on how to customize your dynamic stamp, be sure to check out Thom Parker’s book on All About PDF Stamps in Acrobat and Paperless Workflows. It covers everything including using checkboxes and custom dialogs on dynamic stamps. So, now hopefully you have enough reference material to guide you through the process of creating, using, and customizing your dynamic stamps.
