Abstract:
1. A method of marking on a material with a laser beam, the method comprising: receiving user-specified characters for a mark to be applied to the material with the laser beam; obtaining a quality setting; loading a pre-defined font definition from a machine-readable medium, wherein the pre-defined font definition specifies character segments for each of multiple character fonts, and the specified character segments comprise horizontal and vertical line segments, diagonal line segments, and curve segments; selecting a pixel grid from a group of available pixel grids of different grid sizes based on the quality setting; generating a set of multiple spaced locations in the selected pixel grid based on character segments of the pre-defined font definition that correspond to the user-specified characters; and marking the material with the laser beam by directing the laser beam to dwell at the locations and move between the locations without deactivating the laser beam.
