Producing multicolored surface on ceramic element or glass by drop-like application of different colored primary ceramic process color inks containing carrier fluid onto a surface of ceramic element or glass, comprises: printing on top of one another primary process color inks to obtain mixed color ink; subsequently firing applied ink drops; adding at least one (photo)oligomerizable or polymerizable additive and optionally photoinitiator to the color inks; and prior to overprinting an ink drop with an additional ink drop, at least partly setting the first ink drop. Producing a multicolored surface on a ceramic element or glass by drop-like application of different colored primary ceramic process color inks containing a carrier fluid onto at least a portion of a surface of the ceramic element or glass, comprises: printing on top of one another at least two primary process color inks to obtain a mixed color ink; subsequently firing the applied ink drops; adding at least one (photo)oligomerizable or polymerizable additive and optionally at least one photoinitiator to the color inks; and prior to overprinting an ink drop with an additional ink drop, at least partly setting the first ink drop, where after the application of an ink drop of a process color ink and before a further ink drop of a process color ink is applied onto the ink drop, the viscosity of the previously applied ink drop is increased. Independent claims are also included for: (1) a printing ink system comprising several differently colored, primary ceramic processing color inks, from which a mixed color ink is produced by printing over one another at least two color inks, where each of the process color ink comprises at least one inorganic pigment, a frit, a dispersing agent, an organic carrier fluid, and (photo)oligomerizable or polymerizable additive and possibly at least one photoinitiator; and (2) a device (1) for producing multicolored surface on a ceramic element or glass by the drop-like application of differently colored, primary ceramic process color inks on at least one portion of a surface of the ceramic element or glass, where the mixed colors are produced by printing on top of one another at least two primary process color inks, comprising several delivery elements for the process color inks and a support device for depositing the ceramic element or the glass during the application of the process color inks, where on or adjacent to the delivery elements or a group of delivery elements where a light source is arranged and/or the delivery elements are arranged in several print heads (6) and a heating device is arranged between the print heads. |
