Abstract:
A method of manufacturing opaque rib structures on a substrate, the method comprising:forming a temporary mask on portions of a surface of the substrate, said mask leaving a plurality of areas of the substrate surface exposed; depositing a layer of a glass paste comprising glass frit, opaque pigment and a curable organic medium over the substrate surface and temporary mask; molding the paste into rib structures in said exposed areas of the substrate surface not covered by said mask by pressing a mold surface having a pattern of recesses corresponding to the desired rib structures against the paste coated surface and at least partially curing the curable medium; removing any residual layer of paste present on the temporary mask; removing the temporary mask from the substrate; and firing the substrate with the molded rib structures thereon.
