Title:
GLASS PANELS PARTIALLY PRINTED WITH CERAMIC INK LAYERS IN SUBSTANTIALLY EXACT REGISTRATION
Document Type and Number:
WIPO Patent Application WO2004030935
Kind Code:
A3
Abstract:
The present application relates to a method of making a glass panel that 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, said layers being in substantially exact registration. The substantially exact registration is achieved by the application to a sheet of glass (10) of a plurality of superimposed layers (14, 20), one of the layers containing a ceramic ink comprising glass frit, in a print pattern. The sheet of glass and plurality of layers applied thereto are subjected to a heat treatment process which causes the glass frit to fuse to the glass and bind at least one layer of ink within the print pattern. Any ink not within 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.
