Abstract
Abstract The disclosure concerns an identification card containing information such as name, account number, photograph 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.
