RUBBER ARTICLES WITH DIGITAL CODING AND IDENTIFICATION OF THE DIGITAL CODING

摘要

The invention is related to a method of providing a rubber article (100) with a digital code pattern (102), wherein the rubber article (100) comprises a cured polymer material (104), the method comprising: Generating, e.g. by means of electromagnetic radiation (110), a digital code pattern (102) in the cured polymer material of the rubber article, the digital code pattern (102) comprising a first surface portion (106) and a second surface portion (108) having different optical reflectivity. Generating the digital code pattern (102) may include generating protrusions (114) or holes (126) in the second surface portions (108). The digital code pattern (102) may identify the rubber article (100) e.g. within a batch of rubber articles. The invention is also related to a rubber article comprising a digital code pattern, a rubber article marking device and a computer program product for controlling a rubber article marking device.
