<p>This invention is a process for a production basis relief decorating of ceramic articles. The process provides for a special technique for screen printing of relief features onto the surface of a transfer decal sheet (13), typically a decal sheet that has previously been printed with a conventional, two-dimensional primary design (19). The new process includes a screen printing stencil (31) of unusual thickness characterized by having non-convergent through openings (32). Ceramic inks are formulated to heavy viscosity in excess of one million cps. The ink is flow resistant in character, and is forced through the stencil openings by a slow moving squeegee (42). The printed design is transferred to a ceramic article (10) for the decal sheet, and is then fused to the ceramic article by kiln firing in the usual way. The relief design elements (12, 45) stand out prominently in three dimensions on the ceramic article.</p> |
