Abstract
1337927 Electrolytic marking stencil P F ERICHSEN 1 May 1972 20232/72 Heading C7B A stencil 10 for electro-chemically marking a grid on a metal specimen 20 comprises a porous, non-stretching and non-distorting fabric 12 filled with a photo-resist 13. The photoresist also forms a masking layer 14 on the side of the stencil which is to face the specimen. The stencil is produced by applying a liquid photoresist to a polyester or metal fabric, sandwiching the fabric in foil then hot rolling. The rolls may be maintained at different temperatures. Opening 15 corresponds to a line in the grid to be marked on the specimen.
