A method of forming a patterned rotary printing screen is disclosed. According to one embodiment, a non-photosensitive mask is applied to a mandrel, and portions of the mask are removed by a laser to expose portions of the underlying mandrel. The mandrel is immersed in a metal-plating solution according to known Galvano-type techniques so that metal is deposited in the areas where the mandrel is exposed to form a printing screen. The screen is then removed from the mandrel for subsequent screen printing operations. As disclosed herein, the processes of the present invention eliminate the need for photosensitive materials and procedures used in conventional Galvano and lacquer screen-forming processes.
