I have to design a document for internal use that needs a unique serial number on copy of the sign off sheet.
I'm aware that InDesign has a numbering function (to number book/magazine pages) but what I'm looking for is something that's a but smarter than 1,2,3,4... I need it to put out a serial number mixed of letters and numbers preferably adhering to a set pattern.
Is there a way one can insert a variable into a pdf or InDesign doc so that each time it's printed it will print a unique serial number onto that page?
The only other way I could think of doing this was to make a web page html/php and have the serial number done on the server and the print page styled with a print style sheet. But this seems like a rather long way to go around the issue.
