A system directs a laser beam to mark a material with an alphanumeric code. Character and quality information corresponding to a mark to apply to the material with the laser beam can be received, a font definition that specifies character segments can be obtained, a set of multiple spaced locations can be generated from the character segments in accordance with the character and quality information, and the material can be marked with the laser beam by directing the laser beam to dwell at the locations and move between the locations without deactivating the laser beam.

Laser marking using scalable fonts

A system converts graphic images, such as those created by graphics applications, to a format that can be efficiently printed on a material by a laser printing system. An image can be converted to a set of locations by defining progressively smaller contours of the image, and a material can be marked by directing a laser beam according to the locations. Converting the image can involve identifying a set of points that trace boundary pixels of a marking area of the image such that the set of points form a contour of the marking area, removing the boundary pixels from further consideration with respect to defining the contours for the marking area, repeating the identifying and the removing until all pixels of interest in the marking area have been considered, and determining the locations from the identified points.

Filling an area of an image marked on a material with a laser

A method of controlling a laser to print symbols of an image on moving products with various velocities. The method may include grouping, organizing and/or moving symbols to stripes, leading edge clipping correction, trailing edge clipping correction and updating clipping correction in real-time.
