Abstract
A layered printing plate that attains a high degree of clarity and improved clean out. The printing plate may include an oleophilic substrate, a laser absorbing imaging layer and an oleophobic silicon layer. One embodiment utilizes an amine resin rather than a traditional polymer as the basic organic matter of the imaging layer, adds of colloidal silica into the imaging layer to improve the cleanout properties, and utilizes a substrate that absorbs IR radiation rather than reflects it.
Claims7
A waterless lithographic printing member, comprising:
- a. an oleophilic solid substrate;
- b. a laser-absorbing imaging layer positioned above the substrate, wherein the imaging layer comprises an infrared-absorbing substance;
- and
- c. a silicone layer positioned above the imaging layer, the silicone layer being oleophobic,
- wherein the laser-absorbing layer contains a binder consisting essentially of CYMEL 327.
