Method and device for generating color images on substrates containing color bodies and products thus manufactured

摘要

Method for generating a mark, a pattern, a symbol and / or a multi-colored image (8) on a substrate (2) with capsules (1; 30) arranged thereon containing color bodies compounds of dyes or pigments, in which the action of a laser beam (23) the color effect is released, being arranged different caps (1) with at least two, in particular three, color effects different on or in the substrate (2) respective, with the following process steps: a- generating a color chart (14), in which is contained the effect of possible individual color of capsules containing individual color bodies (1) as a function of their spatial coordinates on or in the substrate (2); b- irradiating with spatial resolution so that only individual capsules color bodies (1) for color effect and so releases these dyes with a laser (23) open, in particular an IR laser or a UV laser, at a single frequency, based on the color chart (14) for generating a color effect resulting from the dyes released.
