Abstract

Marking of documents by means of a laser beam is a secure and efficient personalization method. The marking is based on a carbonization process, which is caused by a focused laser beam. The process of gray scale laser marking is today's standard on ID documents e.g. driver's licenses, passports. - Now it is possible to personalize these documents with colored lettering, company logos or images in photo quality, using a new laser marking method: CYMart. This development offers the possibility of a more flexible layout arrangement and increased information content. In addition, CYMart provides a new, active security feature for preventing forgeries, particularly in the ID market. The CYMart technology enables the document to be marked inside the multilayer structure, as opposed to a color print on the surface of a document. In combination with other security features e.g. Kinegram or security printing a very high level of protection against forgery is possible. The generation of color is based on a wavelength sensitive process. Multicolor is achieved by the combination of RGB laser beams and photosensitive materials which are integrated into the card layer structure.
