I understand how Safeguard works (besides priced out of reason) and the other program appear to also require a plugin to be installed on the viewer's computer. That can get ugly.
I was trying to come up with a simple deterrent to a user downloading and printing more than one coupon for a pet food company we do work for. I do realize that just about everything can be breached, but wanted to try and deter all but the most determined.
I do have it set so that an IP address can only access it once, but short of eventually implementing a more extensive coupon delivery program (in the works), was hoping for a quick and easy solution that Adobe might have.
I'd say in that situation, a static PDF is not your solution. It's far easier to generate a uniquely-coded "ticket" using conventional web programming (PHP, etc.), and while it's just as impossible to control print quantities, you wouldn't care if the serial number only worked once. If the end result has to be a PDF, then there are powerful (and free) libraries for PHP, Java etc. that a website can use to construct a dynamically-generated PDF file per request - such as TCPDF. All the major sites that use coupons generate them using these methods, so the instance of the coupon is meaningless, it's the data on it that matters.
