Publication number: 20110310205Abstract: The invention relates to a method for printing a substrate (7), in which ink is transferred from an ink carrier (3) to the substrate (7) in accordance with a predefined pattern by energy being introduced into the ink through the ink carrier (3) by a device for the introduction of energy (11), the ink carrier (3) and the substrate (7) not coming into contact. The substrate (7) is introduced into an electric field, so that a homogeneous charge field is produced on the surface of the substrate (7). The invention further relates to a printing machine, comprising an ink carrier (3) which can be coated with an ink to be printed, and a device (11) for the introduction of energy into the ink, the device (11) for the introduction of energy being arranged in such a way that the energy can be introduced into a printing area (9) on the side of the ink carrier (3) facing away from the ink, so that the ink is transferred from the ink carrier (3) to a substrate (7) to be printed in an area of action of the energy.Type: ApplicationFiled: December 14, 2009Publication date: December 22, 2011Applicant: BASF SEInventors: Frank Kleine Jäger, Jürgen Kaczun, Udo Lehmann

Publication number: 20110298878Abstract: 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.Type: ApplicationFiled: December 14, 2009Publication date: December 8, 2011Applicant: BASF SEInventors: Frank Kleine Jäger, Jürgen Kaczun
