Ink jet printer ink for printing on ceramics or glass
First Claim
1. An ink comprising an inorganic pigment, wherein the ink is usable in an ink jet printer for printing onto ceramics or glass to provide a decoration thereon following subsequent firing, said ink further comprising a flux for preventing degradation of the ink during firing, the maximum particle size of the pigment and the flux being sufficiently small not to block the nozzles or the filters of the printer, and the particle size range being sufficiently narrow for the ink to have a low enough viscosity for the printer to operate.
