The calibration images (12) are engraved on a predefined substrate surface (14, 15) of a substrate (16) by varying only a single laser parameter. Based on measured colour values of the engraved calibration images, a relationship between said colour values and a predefined laser parameter value, for example, a predefined laser power, is established. This relationship is then used to generate a map for mapping a grayscale value of an input image to a grayscale value of an output image, which is then engraved on the substrate (16) while varying the same laser parameter that was varied during the calibration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of generating a map for use in a laser engraving process and laser engraving method","description":"A laser engraving apparatus (100) is calibrated using a number of predetermined calibration images (12).
