Systems and methods for ink-based digital printing using image offset configuration

摘要

An ink-based digital printing system includes an imaging member having an imaging surface; a dampening fluid metering system, the dampening fluid metering system being configured to apply a layer of dampening fluid to the imaging surface; an inking system, the inking system being configured to apply radiation-curable ink to the imaging surface of the imaging member after the dampening fluid layer is patterned according to digital image data using a laser imaging system; and an offset member, the offset member forming a first ink transfer nip with the imaging member, the imaging member and the offset member being configured for transferring the ink image from the imaging surface to an offset member surface of the offset member.

1. An ink-based digital printing system including an imaging member having a reimageable imaging surface, a dampening fluid metering system, the dampening fluid metering system being configured to apply a layer of dampening fluid to the imaging surface, and an inking system, the inking system being configured to apply ink to the imaging surface of the imaging member after the dampening fluid layer is patterned according to digital image data using a laser imaging system, the system comprising:
an offset member, the offset member forming a first ink transfer nip with the imaging member, the imaging member and the offset member being configured for transferring the ink image from the imaging surface to an offset member surface of the offset member; and a rheological conditioning system, the rheological conditioning system being configured to irradiate ink disposed on the offset member before the ink is transferred from the offset member.
