Method for printing.

摘要

Heat resistant substrates of glass, metal or ceramic are coated by applying onto the substrate a layer of radiation-curable and firable printing ink containing an inorganic ceramic colour, curing the layer by exposure to radiation and applying onto the substrate on or adjacent to the radiation curable ink a firable printing ink in the form of a gel containing a precious metal. The coatings may be applied at successive stations of a single automatically operated printing machine, after which the substrates can be fired.
