During laser engraving, the grayscale or colour images are converted to black/white images during rasterising. The impression of a grayscale image is generated through different point sizes and point distances. However, the human eye perceives the raster as a mixture of colours.
How does this effect laser engraving?
During rasterising, binary information is calculated from image data as: "1 = lasering / 0 = not lasering." Grayscale or color images are then converted to a black-white image that can be laser engraved. There are different algorithms for the arrangement of the individual image points. In JobControl® laser software, you can simply select the desired raster algorithms.
