  • Patent number: 12145386
    Abstract: A method for preparing a laser marking system to create a colored laser mark on a specimen by providing a laser marking system and a specimen comprising a surface layer, where the laser marking system has a preset number of laser parameters, and performing an exploration of a first gamut specified by the laser marking system and the specimen. The method further generally comprises creating a design space with a preset number of design points; performing a marking of a sample on the specimen for each design point; measuring the sample using at least one detection device and determining a performance point for each design point; evaluating the performance space with regard to preset performance criteria using an evaluation device; generating an offspring design space with offspring design points; and creating a first gamut using a subset of performance points.
