Systems and methods for ink-based digital printing using variable data lithography inkjet imaging system

摘要

A system for ink-base digital printing includes an imaging member; an inkjet system for applying a base marking material to the imaging member to for a pattern according to digital image data; a dampening fluid metering system configured for applying dampening fluid to the imaging member after the applying base marking material; and an inking system configured for applying ink to the imaging member, the ink adhering to the base marking material pattern. Methods include jetting base marking material onto the imaging member according to image data, applying dampening fluid, inking the imaging member, and optionally pre-curing the resulting ink image, which enables 99% or greater transfer of the applied ink from the imaging member to a substrate.

1. A water dilutable ink-based digital printing system, comprising:
a central imaging member having an imaging surface; an inkjet system configured to jet base marking material configured to attract water-based ink onto the imaging member surface, the inkjet system being configured to jet the base marking material according to digital image data for forming a base marking material image; and an inking system, the inking system being configured to apply water-based ink onto the imaging member surface for forming an ink image overlaying the base marking material image on the imaging member surface, the base marking material image interposing and directly contacting each of the imaging member surface and the ink image.
