A system and method for selectively process material on a processing surface
of
a printing form to create a fine structure or pattern for images or text. At least
one fiber laser comprising a pump source and a laser fiber is provided. A laser
gun is mounted adjacent the printing form and has at least a focusing optics. The
fiber laser outputs a laser beam which is diffraction-limited to permit the focusing
optics to focus the laser beam onto the processing surface of the printing form
as a spot having a spot size sufficiently small to process the processing surface
to create the fine structure or pattern images or text.
