A system for marking pellet shaped articles includes a conveyer to convey the pellet-shaped articles along a transport path, and a laser to generate at least one beam to print or etch information on one or more of the pellet-shaped articles. The information includes at least one of alphabetical characters, numeric characters, and/or logos. The information comprises at least one engraving, e.g., two engravings or holes, apertures, etc., that are adjacent one another and at least partially overlapping. The system includes a controller to control x and y or x, y and z coordinates of the beam of the laser relative to the transport path to align the beam with the one or more of the pellet-shaped articles. |
