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.
