Abstract
The present invention relates to a method of engraving objects which circumvents the necessity of mechanically scrubbing the engraved surface to remove fillers. Specifically, in the method of the present invention, the fillers are applied directly to the resist stencil instead of being applied to the object to be engraved. Removal of the resist stencil simultaneously removes the filler from the engraved object.
Claims19
A method of engraving a porous, rough or frosted surface of a randomly shaped object by sandblast engraving without the use of a filler material comprising the steps of:
- (a) providing a resist stencil material having at least one surface with an adhesive material;
- (b) applying an additional coat of an adhesive material to said surface of the resist stencil under conditions sufficient to permit the adhesive to become tacky;
- (c) applying the tacky adhesively coated surface of the resist stencil to a surface of the object to be engraved, wherein the resist stencil with its tacky adhesively coated surface is capable of being subjected to engraving forces caused by sandblasting without dislodging from the surface of the object to be engraved;
- (d) engraving the surface of the object;
- and
- (e) removing the adhesively coated resist stencil from the porous, rough or frosted surface of the engraved randomly shaped object,
- whereby the adhesive material is simultaneously removed from the engraved randomly shaped object with the resist stencil thereby circumventing the need for any mechanical scrubbing and washing of the engraved surface to remove residual adhesive material after the engraving.
