Abstract
Process for marking an article by means of a pattern, which contains geometrically encoded information and can be evaluated with optical means by irradiation with light, there being provided on the surface of the article in a spatial arrangement in relation to an information pattern which can be evaluated by means of irradiation with UV light but is not visible to a human viewer a further information pattern which can be evaluated by means of visible light, the evaluation of the information contained in the two markings being able to be performed exclusively by means of the information pattern which can be evaluated by irradiation with UV light.

A process for marking an article by means of a pattern, which contains geometrically encoded information and can be evaluated with optical means by irradiation with light, and for reading the information, characterized in that a first information pattern, which can be evaluated by means of the irradiation with UV light but is not visible under visible light, and a second information pattern, which can be evaluated by means of visible light, are applied on a surface of the article in a spatial arrangement in relation to each other and the information contained in the two patterns is encoded in such a way that its evaluation can be performed exclusively by means of the first pattern, and in that the signals obtained upon reading out the first pattern are subjected to a decoding logical operation together with the signals obtained upon reading out the second pattern.
