摘要

1. Procedure of printing on plastic sheet in the mass production of identity cards and credit cards, which is characterized by the personal data of each individual (including fingerprint and signature, which are previously digitized if required by the type of carnet-) collected in a decentralized way on magnetic support are printed centralized directly and massively on plastic sheet, by means of a printer "non impact" of coherent monochromatic ray of light controlled by computer, making the impression in such a way that the personal data recorded on the magnetic support feeds the electronic logic that, through a memory of characters and graphic elements, causes the coherent monochromatic light beam to be deflected by modulating its incidence on a drum coated with a photoconductive layer through an optical system, with the object that reproduces on that photoconductive surface the image of each character or graphic, which is then revealed in a camera obscura by powder thermoplastic toner powder or micronized liquid, the toner particles adhering to the points of the drum where the beam incident has produced the point discharge, also being characterized by the image thus coated with toner is then transferred, by an electric field, to the plastic sheet entrained by the backing paper.
