METHOD AND SYSTEM FOR DIRECT-TO-PRESS IMAGING

Document Type and Number:

WIPO Patent Application WO2003010600

Kind Code:

A3

Abstract:

A direct-to-press imaging method comprises: (a) applying an imageable coating to a printing cylinder, wherein the imageable coating comprises a composition such as a thermally switchable polymer which changes affinity for a printing fluid upon exposure to imaging radiation such as infrared radiation delivered imagewise via a laser, and the imageable coating is substantially insoluble in the printing fluid; (b) imagewise exposing the imageable coating to actinic radiation to obtain an imaged coating; (c) printing a plurality of copies of an image from the imaged coating; and (d) reapplying the imageable coating as desired by repeating steps ( a) through (c) at least once without substantially removing the prior imaged coating before reapplying the imageable coating.
