Laser coding technology is a method of printing information, such as barcodes or text, onto a substrate using a laser beam. The process starts with a laser beam being directed at the surface of the substrate. The laser beam is modulated, or turned on and off, in a pattern that corresponds to the desired image or text. The laser beam’s interaction with the substrate causes a physical or chemical change, such as a burn or a color change, on the substrate surface. This creates the desired image or text on the substrate. Lasers can mark small text very quickly. Multiline text, barcodes and logos take a lot of time with a laser
