Abstract
Halftone printing of a plurality of different colors is employed to produce a composite graphic display on the surface of the glass. Precise alignment is utilized in order to register the halftone printing screens for each color that is deposited on the glass surface. The opaque enamels employed in the decorative process are carefully balanced with respect to each other to obtain the desired color hues. The deposition angles for the alignment of the halftone dots is controlled to minimize the undesirable moire effect.
