Abstract: A process for producing screen material by electrodeposition of metallic material on a matrix. The matrix has a smooth surface having conductive and non-conductive surface areas and material such as nickel is electrodeposited on the conductive areas in successive steps. Insulating material is applied between electrodeposition steps to confine the nickel to the desired size. Also disclosed is a similar method for making screen printing blocks by electroplating on a conductive surface wherein the areas not to be plated are coated with a photoresist.

Abstract: To improve the detail on screen printing, in which images are applied to a printing grid or screen in which a photo-sensitive layer is utilized to be exposed in accordance with the image or composition to be printed, and the non-exposed image portions are removed before printing, the screen is pre-processed to provide it with a smooth surface so that the photo-sensitive layer can, itself, be applied on the screen with a smooth surface of uniform and controllable thickness directly over the printing grid; in a preferred form, the interstices of the printing grid or screen are filled with a filler, and the surface of the grid and the filler is then treated to remove that portion of the filler which is above the grid elements, leaving the filler within the interstices, and a smooth surface over which the photo-sensitive layer can be applied.
