Claims6
A substrate comprising:
- personalization data that is visible on a surface of said substrate, said personalization data having been implemented by using a laser beam-type personalization means;
- and
- anti-forging means comprising a laser inscribed graphic printing pattern, arranged on at least a part of said surface that is unoccupied by said personalization data, wherein said anti-forging means (i) is invisible to the naked eye and (ii) reacts with an additional personalization data on said at least part of said surface, also implemented by using a laser beam-type personalization means so that said additional personalization data exposes said anti-forging means therein on said at least part of said surface of the card.
A process for the production of a substrate that comprises:
- arranging, during a personalization stage, personalization data on a surface of the substrate by means of a laser beam-type personalization means so that said personalization data is visible on said surface;
- applying, by a laser beam, during a securitization stage, an anti-forging means on at least a part of said surface that is unoccupied by said personalization data, wherein said anti-forging means (i) is invisible to the naked eye and (ii) reacts with an additional personalization data on said at least part of said surface, also implemented by using a laser beam-type personalization means so that said additional personalization data exposes said anti-forging means therein on at least part of said surface of the card.
