Abstract
A glass panel is partially printed with a plurality of layers in the form of a print pattern which subdivides the panel into a plurality of discrete printed areas and/or a plurality of discrete unprinted areas, the layers being in substantially exact registration. Exact registration is achieved by the application of a plurality of superimposed layers to a sheet of glass. One layer contains-ceramic ink comprising glass frit. The glass sheet and layers are subjected to a heat treatment process which causes the glass frit to fuse to the glass and bind at least one other layer of ink within the print pattern. Ink outside the print pattern is burnt off and/or vaporised during the heat treatment process and/or removed by a subsequent finishing process, to leave the desired layers in substantially exact registration within the print pattern.
