How to add a permanent watermark to PDF

[haiyangp4660650]

Hi,

I am trying to find a way to add a permanent watermark to the PDF so that it cannot be changed, deleted, or hidden (for example, covered by a white comment box), even in Acrobat editor.

We would like to leave the rest of the PDF to be editable, so protecting the entire PDF via password is not an option for us.

I also tied a JavaScript-based route, but it requires the Reader/Editor to enable the JavaScript and users may refuse to do so.

Now I got sucked...Can anyone help throw some light on it?

Much appreciate it.

Not really possible, sorry.
