Abstract: A method for coating a printing screen with a sealer to avoid pinholing and damage to the screen from extended use. The method includes coating the inside of the screen with a photo emulsion, exposing the emulsion to the image to be printed, and etching out the exposed screen. Next, applying to the outside surface of the etched out screen a sheet of easy removable pressure sensitive vinyl, and next treating the etched out screen with a sealing composition, which provides a protective barrier for that part of the screen that prevents ink from printing. The sealing composition is advantageously a two part epoxy resin or an air-moisture curing urethane polymer.
