Abstract:
A reusable, mask having rigidity and with a single-piece edge, to prevent selected portions of a substrate from being coated with a coating so as to provide a desired coating shape including any deletions of the coating on said substrate where ghosting along an edge of said coating is reduced, comprising:one major surface having a horizontal surface area,another major surface opposing the first side having a larger horizontal surface area than the first surface wherein at least the surface with the larger surface area for the mask has the configuration of the shape of the desired deletion of the coating on a substrate to inhibit the deposition of the coating on the substrate;one or more sides between the first and the second major surfaces arranged with one or more segments that slope inwardly from the surface with the larger surface area to the surface with the smaller surface area, wherein the slope is greater than 0.degree. up to 90.degree. to form an edge for the mask;at least one friction enhancing member associated with the major surface with the larger surface area so that the mask is adapted for contact with a substrate to be coated through the at least one friction enhancing member.
