Abstract
An ink-based digital printing system for variable data lithographic printing includes an imaging member having a surface configured to absorb dampening fluid. A dampening fluid patterning system jets dampening fluid onto the imaging member surface according to image data to form a dampening fluid pattern. The system includes a transfer member that receives the jetted dampening fluid pattern from the imaging member at a dampening fluid loading nip for subsequent inking of the dampening fluid pattern to form an ink pattern. The ink pattern is transferred to a substrate from the transfer member at an ink pattern transfer nip.

A method for ink-based digital printing, comprising:
- jetting a dampening fluid pattern onto a conformable porous surface of an imaging member configured to swell after absorbing the dampening fluid pattern, the jetting of the dampening fluid pattern onto the conformable porous surface of the imaging member including jetting the dampening fluid pattern of silicone oil onto a silicone surface of the imaging member;
- transferring the dampening fluid pattern to a transfer member at a dampening fluid pattern loading nip defined by the transfer member and the imaging member;
- applying ink to a surface of the transfer member having the dampening fluid pattern to produce an ink pattern;
- and
- transferring the ink pattern to a substrate at an ink pattern loading nip defined by the transfer member and a substrate transport system.
