How do you add an undetectable watermark to a document?

Is there an app/website out there that lays an undetectable watermark into a document, that when it is attempted to be photocopied, the watermark appears? Example: So if someone were to print using regular paper and ink, the document would photocopy with a VOID watermark.

    To actually answer your question - you can't. Not using regular inks and paper anyway. To make a watermakr magically appear on copied papers requires either an expesnive custom print job or use of special papers. I tried to find a consumer supplier online or on amazon, but couldnt find any. I believe the term is "void pantograph", but "anticopy paper" turned up a few results too.

    You could follow these steps for MS Office plus protect all your documents from changes in order to avoid people removing the watermark.

    Protect documents (note that there are two variations: Protection against viewing and protection against modifications): http://office.microsoft.com/en-us/word-help/protect-a-document-from-unauthorized-changes-HP001044674.aspx#_Toc280362682

    Hope it helps.

    If you have Adobe Acrobat (not the Reader but the entire suite) you can also add a watermark from there.
