ABSTRACT:
In the method for the authentication of identification features that are embossed on a packaging foil together with satin-finishing and the embossing of logos, a number of identification features is embossed on-line as a pattern and read by a suitable apparatus and evaluated by means of an image evaluation method.The embossing device (1) suitable therefor includes at least two embossing rollers (2, 3, 15), a reading unit, and an evaluating unit, one of the embossing rollers (2) being driven by the motor drive mechanism (5) and having individual teeth (8) of which a number of teeth for embossing identification features have a different shape, height, or surface structure while the remaining teeth serve for satin-finishing, and one of the mating rollers (3) being provided with circumferential rings (10).Such a method and such a device allow a relatively simpler embossing device with relatively lower requirements with regard to the embossing quality than in methods of the prior art.
