Abstract
A method for ink-based digital printing includes applying a uniform layer of dampening fluid to a surface of an imaging member; laser patterning the dampening fluid layer by selectively removing portions of the dampening fluid according to digital image data; and inking the laser-patterned dampening fluid layer on the imaging member surface with a aqueous heterogeneous ink to form an ink image, wherein the aqueous heterogeneous ink self-coalesces before the ink is transferred from the imaging member surface.

A method for ink-based digital printing, comprising:
- applying a uniform layer of dampening fluid to a surface of an imaging member;
- laser patterning the dampening fluid layer by selectively removing portions of the dampening fluid according to digital image data;
- and
- inking the laser-patterned dampening fluid layer on the imaging member surface with an aqueous heterogeneous ink comprising polymeric nanoparticles, optionally swellable with the ink vehicle, to form an ink image.
