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.
Abstract:
An ink composition or ink concentrate for variable data lithographic printing or ink jet printing includes a nano-particle polymer or blend of nano-particle polymers, wherein the polymer or polymers of the blend are water dispersible at temperatures below 100 degrees Celsius; and solids content is in an amount of greater than 25 percent by total weight.
