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.
Claims21
A printing process comprising:
- disposing a substrate to be printed opposite an ink carrier including an ink layer,
- regionally heating the ink layer in such a way that a bulge is formed in the ink layer, wherein the bulge contacts the substrate, and
- moving the substrate relative to the ink carrier to thereby cause ink splitting onto the substrate.
A printing process comprising:
- opposing a substrate to an ink carrier including an ink layer to provide a gap between the substrate and the ink layer,
- heating the ink layer to form a bulge in the ink layer, the bulge spanning the gap, and
- providing relative movement between the substrate and the ink carrier and splitting at least a portion of the bulge from the ink layer onto the substrate.
A printing machine comprising:
- an ink carrier including an ink layer, and
- a laser scanner,
- the printing apparatus being configured to perform a process comprising:
- disposing the ink carrier opposite a substrate to be printed,
- regionally heating the ink layer with a laser emitted from the laser scanner to form a bulge in the ink layer, and
- splitting ink onto the substrate by permitting the bulge to contact the substrate and moving the substrate relative to the ink carrier.
