摘要：The marking method thus disclosed consists in making a colored pattern which is formed by at least two different colors and contrasts on a dark colored or black surface of a rubber item. The inventive method comprises a preparation stage for a composition of light colored rubber consisting of at least one elastomer, at least two different light colored coloring agents providing said composition with an initial color, followed by a stage in which a limited amount of dark colored or black masking agent is incorporated into the colored composition in order to darken or mask the initial color of the rubber composition. The marking method consists in interacting a first laser beam having the appropriate characteristics so as to create a first colored part of the pattern with a second laser beam having the appropriate characteristics to create a second colored part of the pattern.
