Hi everyone, I need to add some layer of security, so some pdfs i generate need to be impossible to physically copy after being printed out.
I know there ist he EURion constellation (a pattern of nearly invisible dots that are printed on bak notes, so you cannot photocopy bank notes). I would like to do something similar, but I don't know how i should do that without tiling an image on top of my document. I know how i could set my printer to embed some copy protextion pattern, but either the printer instantly triggers and prints unathorized copy on top of my document, or it is very visible on dark areas. Also some sample documents might be sent to customers and i would like to retain the copy protection properties for the samples, so they can test the tamper protection themselves. Do you have any ideas, or hints for me? -- Solupharm Pharmazeutische Erzeugnisse GmbH Industriestra?e 3, D-34212 Melsungen Tel: +49 (5661) 7305-767 Email: stefan.schm...@solupharm.com Homepage: https://www.solupharm.com [lslp_ogo] [Vision_mission] Folgen Sie uns auf Facebook!
