seen and device to framstella text and / or signs of an already developed film

摘要

Method and device for producing text and/or characters on film that has already been developed, preferably colour and sound film, comprising:a) a coating device (2) designed to apply a coloured coating to all or part of the film (1) as it passes through the deviceb) the film (1) is then designed to pass a text application device (3) that includes a laser beam (3a) that is regulated to write the desired text on the coatingc) the colour and intensity of the laser beam (3a) per surface section is determined by the thickness and colour nuance of the coating so that it is able to evaporate the coating at the spots where text is to be appliedd) the film (1) is then allowed to pass to a text developing device (4) in which the film surface is subjected to processing, preferably an etching, staining and/or bleaching, so that the pigment on the film surfaces under the coating where text is desired is affected,e) and any remaining coating applied at "a" is removed as needed in a coating removal device (5).IMAGE
