<p>PROBLEM TO BE SOLVED: To provide a method for transferring an ink image using a film-forming aqueous ink that is partially coalesced and transferred to a substrate before a fully coalesced film is formed.SOLUTION: A method for ink-based digital printing includes: a step of applying a uniform layer of dampening fluid to a surface of an imaging member 110; a step of laser-patterning a dampening fluid layer by selectively removing portions of the dampening fluid according to digital image data; and a step of inking the laser-patterned dampening fluid layer on a surface of the imaging member 110 with an aqueous heterogeneous ink to form an ink image, in which the aqueous heterogeneous ink self-coalesces before the ink is transferred from the surface of the imaging member.</p> |
