Method to make a built up area rotary printing screen

摘要

A rotary printing screen is made with selected areas being provided with a perforated mesh region through which printing ink may be passed. These mesh areas are provided with a mesh pattern recessed back from the exterior surface of the rotary printing screen so as to permit greater ink deposition thicknesses. The screen is formed by an electro-metal deposition method which provides a basic conventional screen structure. The mesh areas are then masked and an additional deposition of material is provided in the non-mesh areas to build up these areas and, consequently, provide a recessed area in the region of the originally formed mesh design.
