A printing rubber blanket includes base layer, a surface rubber layer provided on one surface of the base layer and metal layer provided on the other surface of the base layer on the opposite side of the surface rubber layer. The metal layer includes a passivation layer on at least a surface thereof on the opposite side of the base layer.

Provided is a printing blanket that is unlikely to cause portions uncoated with ink even when the printing-applied surface has protrusions. The printing blanket according to an embodiment of the present invention includes a printing surface to be pressed against a printing plate on which the ink is placed and against the surface on which printing is applied and that is a target of printing. The printing blanket further includes a substrate, an inner coating layer covering at least part of the surface of the substrate, and an outer coating layer covering at least part of the surface of the inner coating layer that is on the side opposite the substrate. The inner coating layer has a smaller Asker C hardness than the substrate, and the outer coating layer has the printing surface on the side opposite the inner coating layer.

Provided herein is an imaging blanket for variable data lithography comprising (i) a substrate and (ii) a thermally-conductive composition disposed on the substrate comprising a silicone elastomer and a thermally-conductive filler selected from metal oxides, wherein the thermally-conductive composition has a thermal conductivity ranging from about 0.6 W/m.sup.2 to about 1.6 W/m.sup.2. Further provided herein a method of making the imaging blanket, as well as a printing system comprising the imaging blanket, wherein the imaging blanket has improved thermal conductivity.

An imaging blanket comprises a base comprising an elastic polymer and sulfur. A barrier layer is on the base and a surface layer is on the barrier layer. The surface layer comprises an elastomer and a platinum catalyst.

An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

The present teachings include a transfer member, a multilayer imaging blanket and a variable data lithography system. The transfer member includes a fluorosilicone surface layer. The surface layer includes mixing a first part and a second part. The first part includes a vinyl terminated trifluoropropyl methylsiloxane, an IR absorbing filler, silica and a first solvent. The second part includes an organo platinum complex having vinyl groups, a methyl hydrosiloxanetrifluoropropyl methyl siloxane having hydrosilane groups an inhibitor and a second solvent. The molar ratio of vinyl groups to hydrosilane groups is 0.7:1.0 to about 1.3:1.0 in the mixture. The mixture of the first part and second is coated on a substrate to form the fluorosilicone surface layer.

The present specification relates to an apparatus for manufacturing a blanket. The apparatus includes a surface plate on which a substrate film is supplied; a coating unit coating a blanket composition on the substrate film; and a comma blade horizontally moving on the surface plate coated with the blanket composition. Of the whole surface of the comma blade, the surface contacting the blanket composition is an angular surface. This application also relates to a method for manufacturing a blanket, a blanket manufactured using the same, a reverse offset printing roll provided with the blanket, and a reverse offset printing apparatus including the same.

The invention relates to a multilayer sheet material 10 in the form of a printing blanket or of a printing plate, in particular for the printing of conical or cylindrical vessels made of, for example, plastic, styropore, paperboard, metal, etc., with a multiple-ply printing layer 1,2 made of at least one polymeric material and at least one other layer 3, 4, where the individual layers form, with one another, an adhesive bond that is not amenable to non-destructive separation.

The upper ply 1 of the printing layer, which during the printing procedure faces toward the object to be printed, comprises from 40 to 80 phr of butadiene rubber (BR) and from 20 to 60 phr of butyl rubber (IIR), and the lower ply 2, which during the printing procedure faces away from the object to be printed, comprises from 80 to 100 phr of butyl rubber (IIR).
