Topic: Adobe Acrobat

Expert: Michael Jahn
Date: 4/27/2007
Subject: Time and Date Expiration of PDF

Question
QUESTION: Hi, do you know of a batch process I could perform to add an expiration date to the bottom of the PDF when it is viewed on screen and/or printed with people using Adobe Reader 7.0 or higher? I have AA version 7.0.8.
ANSWER: Do you want the message to be something like "This offer ends on July 30th at 3:00pm EST" stamped on each page ? If so, you will need a plug-in. A popular one can be found here;

---------- FOLLOW-UP ----------

QUESTION: Thank you for your response. Yes, I wanted the message to be "This document expires 24 hours from "today's date"". But, do you know if there is a javascript available to do this?

Answer
I searched google for "Acrobat Javascript" and found this link - perhaps you could ask somone there.
