For CS5 and ActionScript:
I want to mark an InDesign document I've creating via scripting in such a way that an end user can not get rid of the marking (e.g., when distributing my extension as a trial version). Ideally, I'd want "Trial Version" splashed across each page "indelibly".
How can this be done?
Try using watermark document preference:
There are some properties like text, font, style, rotatio, opacity...
Hope that helps.
Thanks Marijan, but couldn't a sophisticated customer change those settings himself - and thus get rid of the watermark?
Yes they could.
You can create the watermark in a way that it can't be changed without a plugin.
Even then, it's not easy to prevent users from just removing your plugin to change the doc...
