Using Ghostscript Add watermark to PDF for Print Only -

-

i creating program using ghostscript add watermark(stamp) on pdf file. want know, possible add watermark pdf display on print copy of pdf not on computer screen?

i believe can creating optional content group has usage dictionary /print dictionary has printstate key value on. want /view dictionary viewstate key has value off.

you create annotation watermark , have annotation part of optional content group created above. annotation print, not view.

note consuming application decide whether viewer or printer. ghostscript, example, assumes viewer , uses viewstate determine visibility of optional content groups.

you should able construct optional content groups , annotations using pdfmark operations. see adobe pdfmark reference more information.
