Claims
- 1. A method for visibly encoding an indentification card having alphanumeric characters present in a high-embossed form capable of use as a printing block and intermediate areas of card material between the embossed areas and non-embossed areas at which the surface of the card is inclined with respect to the plane of the card, comprising the steps of:
- (a) feeding the personalized card to a laser recording apparatus; and
- (b) encoding the card by inscribing a security pattern on at least a portion of the card material including the embossed characters in the form of, for example, lines, guilloches or characters, by means of the laser beam recorder such that the color of the card material is changed by the inscription and the security pattern extends over intermeidate and non-embossed areas of the card so that, when observed normally with respect to the card plane, the security pattern appears free of distortion.
- 2. A method as claimed in claim 1 wherein, in step (b), the beam of the laser recorder is directed perpendicular to the card plane during the inscribing process.
- 3. A method as claimed in claim 1 wherein, in step (b), the beam of the laser recorder is directed at an angle to the card plane during the inscribing process.
- 4. A method as claimed in claim 1 wherein, during the inscribing process, the beam of the laser recorder is moved and the card is stationary.
- 5. A method as claimed in claim 2 wherein, during the inscribing process, the beam of the laser recorder is moved and the card is stationary.
- 6. A method as claimed in claim 3 wherein, during the inscribing process, the beam of the laser recorder is moved and the card is stationary.
