Abstract:
1. A method of partially imaging a substrate with a plurality of layers within a print pattern which subdivides the substrate into a plurality of discrete printed areas and/or a plurality of discrete unprinted areas, said layers being in substantially exact registration, said method comprising the steps of: (i) applying a plurality of layers of ink to the substrate, wherein one of said layers of ink comprises a mask ink layer located outside said print pattern and which defines said print pattern by forming a negative image of the print pattern, and another of said layers of ink comprises pigment and glass frit, (ii) subjecting said substrate and said plurality of layers of ink to a heat process, wherein during said heat process, said pigment and said glass frit form a durable image material adhered to said substrate within said print pattern and does not form a durable image material outside said print pattern, and (iii) removing parts of said another of said layers outside said print pattern, wherein said parts are burnt off and/or vapourised during said heat fusing process and/or are substantially removed by a subsequent finishing process.
