Abstract: Printing process in which a substrate to be printed is disposed opposite an ink carrier having an ink layer, wherein the ink layer is regionally heated in such a way that bulges are formed in the ink layer, wherein the bulges contact the substrate and wherein ink splitting is brought about by relative movement between substrate and ink carrier.

Abstract: The invention relates to a process for printing a substrate (7) containing curved surface sections by using an ink printing assembly with a movable print head (8) comprising an ink carrier (1) having an ink layer, the ink layer being irradiated regionally in such a way that heat bulges are formed in the ink layer which cause the splitting of ink droplets so that the ink printing assembly is working as nozzle-less droplet ejector for ejecting droplets of ink from the ink layer, where the distance between the print head (8) and the curved sections of the substrate (7) is adjusted by moving the print head relative to the substrate by providing the print head with three degrees of freedom in translation, allowing horizontal (Tx), vertical (Tg) and in depth (Tz) translations.

Abstract: The invention relates to a method for printing a substrate (7) in a printing machine, in which ink is transferred from a flexible carrier (3) to the substrate (7) in accordance with a predefined pattern by energy being introduced into the ink through the flexible carrier (3) by a device for the introduction of energy, some of the ink evaporating in the area of action of the energy and, as a result, a drop of ink (67) being thrown onto the substrate (7) to be printed, this step being repeated at least once, ink being transferred at least partly to the substrate (7) at the same positions in order to intensify the pattern produced. The substrate is transported through the printing machine (1) during the printing and, after the transfer of ink in step (a), the device for the introduction of energy is controlled in such a way that, during the repetition in step (b), the ink is transferred at the same position again as in step (a). The invention further relates to a printing machine for implementing the method.
