Abstract (en)

A support having a graphical image is provided with a security element against copying systems. The security element is a light-diffusing coating applied onto the support and covering the graphical image at least in part. The coating diffuses incident light in a reflecting manner, as a consequence of which the underlying image becomes poor or invisible for a copying system which scans the support by means of light. <IMAGE>
