Anti Scan / Anti Copy Pattern Printed security features integrated in the background printing to protect against simulation through copying. The printed images and patterns contain embedded (hidden) information that is invisible to the naked eye under normal inspection conditions but becomes visible or legible, or causes flaws (mistakes) to appear after copying or reproduction with a scanner. Example: Orientation- and angle-modulated fine-line structures (SAM = Screen Angle Modulation)
