Imaging plate multi-layer blanket

A variable data lithography system, comprising:

• a multilayer imaging blanket including:
• a multilayer base having a lower contacting surface configured to wrap around a printing cylinder of the variable data lithography printing system,
• a platinum catalyzed fluorosilicone surface layer coated about the multilayer base, the fluorosilicone surface layer including carbon black, a silica, a crosslinker, and a solvent, and
• a primer layer between the multilayer base and the fluorosilicone surface layer for improving interlayer adhesion between the multilayer base and the fluorosilicone surface layer;
• a fountain solution subsystem configured for applying a layer of fountain solution to the multilayer imaging blanket;
• a patterning subsystem configured for selectively removing portions of the fountain solution layer so as to produce a latent image in the fountain solution;
• an inking subsystem configured for applying ink over the imaging blanket such that said ink selectively occupies regions of the imaging blanket where fountain solution was removed by the patterning subsystem to thereby produce an inked latent image;
• and
• an image transfer subsystem configured for transferring the inked latent image to a substrate,
• the platinum catalyzed fluorosilicone surface layer including a first part and a second part in combination, the first part having a vinyl terminated trifluoropropyl methylsiloxane, a low-Sulphur carbon black as the carbon black, and the silica, the second part having a platinum catalyst, a methyl hydrosiloxanetrifluoropropyl methylsiloxane as the crosslinker, a polyoxyalkyleneamine derivative as a dispersion stabilizer, and an inhibitor.

A method of manufacturing a multilayer imaging blanket for a variable data lithography printing system, comprising:

• a platinum catalyzed fluorosilicone surface layer prepared from a mixture of a first part and a second part,
• the first part having a vinyl terminated trifluoropropyl methylsiloxane, a low-Sulphur carbon black as the carbon black, a silica, and a solvent;
• the second part having a platinum catalyst, a methyl hydrosiloxanetrifluoropropyl methylsiloxane as the crosslinker a polyoxyalkyleneamine derivative as a dispersion stabilizer and an inhibitor;
• applying a multilayer base composition into a mold structure, the multilayer base having a lower contacting surface configured to wrap around a printing cylinder of the variable data lithography printing system;
• curing the platinum catalyzed fluorosilicone surface layer;
• applying a primer layer over the multilayer base;
• coating a platinum catalyzed fluorosilicone surface layer about the primer layer;
• the primer layer improving interlayer adhesion between the multilayer base and the fluorosilicone surface layer;
• wherein the multilayer base is a Sulphur free carcass includes a plurality of fabric layers including a top layer and a lower layer, a binding layer between the top fabric layer and the lower fabric layer and coupling the fabric layers together;
• and a Sulphur free rubber layer attached to the top fabric layer opposite the binding layer.
