发明名称 CARTE D'IDENTITE ET SON PROCEDE DE FABRICATION
摘要 The disclosure concerns an identification card containing information such as name, account number, photo of the card owner, etc. The card is protected by a superjacent printed security pattern, such as a guilloche, or other pattern which is difficult to imitate, or a homogeneous printed surface. The information is inscribed into the identification card material through the printed security pattern by a laser beam recorder. The energy of the laser and the colors of the printed security pattern are coordinated with each other in such a way that the laser light is not absorbed by the printed security pattern and the latter is not destroyed by the laser light.
