Abstract

Zur Unterscheidung von Originaldrucken gegenüber Kopien wird ein Verfahren vorgeschlagen, das dem Originaldruck feine, unsichtbare Markierungen zuordnet, die durch Kopier­ prozesse nicht reproduzierbar sind. Die Markierungen selbst sind ausschließlich durch optische Hilfsmittel erkennbar. To differentiate between original prints and copies a method is proposed which is based on the original print assigns fine, invisible marks by copying processes are not reproducible. The markings themselves are only through optical aids recognizable.
