An apparatus and method of manufacturing a multiplayer image blanket with a platinum catalyzed fluorosilicone topcoat for a variable data lithography printing system. The blanket consists of multiple layers that may be: (A) a commercial carcass having a Sulphur free rubber outer layer, a suitable primer layer for improving the inter-layer adhesion, and the platinum catalyzed fluorosilicone topcoat; or (B) seamless polyimide substrate coated with a platinum cured silicone, a primer layer, and the fluorosilicone topcoat. 1. A multilayer imaging blanket for a variable data lithography printing system , comprising: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; anda primer layer between the multilayer base and the fluorosilicone surface layer for improving interlayer adhesion between the multilayer base and the fluorosilicone surface layer.2. The multilayer imaging blanket of claim 1 , the fluorosilicone surface layer including a first part and a second part claim 1 , the first part having fluorosilicone claim 1 , the carbon black claim 1 , and the silica claim 1 , the second part having a platinum catalyst claim 1 , a crosslinker claim 1 , and an inhibitor.3. The multilayer imaging blanket of claim 1 , wherein the multilayer base is a Sulphur free carcass including a plurality of fabric layers including a top layer and a lower layer claim 1 , a binding layer between the top fabric layer and the lower fabric layer and coupling the fabric layers together claim 1 , and a Sulphur free rubber layer attached to the top fabric layer opposite the binding layer.4. The multilayer imaging blanket of claim 3 , wherein the Sulphur-free rubber layer is carbon black free.5. The multilayer imaging blanket of ...
