  • Method for engraving articles
    Patent number: 5958170
    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.
