Disclosed is a surface treated doctor blade in which the surface of at least the blade edge portion thereof consists of a surface treatment coating film composed of a first layer consisting of a specific nickel-based plating and a second layer provided thereon which has low surface energy, and in which preferably at least a part of the blade edge end portion of the blade base material is exposed. In the surface treated doctor blade of the present invention, it is possible to improve wear resistance of the blade edge end and to suppress generation of printing failures during continuous printing. Further, in the mode in which at least a part of the blade base material is exposed, it is possible to reduce running-in time for adjustment of contact of the blade edge with the cylinder after replacement of the doctor blade.

An improved printing blanket construction is provided which includes at least a top ply, a bottom ply, and a non-extensible backing ply. The blanket includes leading and trailing edges which are secured directly to the backing ply, where at least a portion of the leading edge forms a contoured edge, a stair-stepped edge, a beveled edge, or a combination thereof. The printing blanket construction having such a shaped leading edge reduces printing gap, reduces the impact forces on the leading edge of the blanket, and protects the blanket from the penetration of ink, solvents, moisture and the like into the blanket plies during use.

The present invention relates to a device for printing cans with different print patterns in the same production sequence, without it being necessary to interrupt the production. Another objective of the present invention is to provide a process for producing cans, which uses a printing device, the can produced by the device and process, and a transfer blanket that is a graphic means that influences the final print patterns of the cans to be printed.

An imaging member includes a surface layer comprising a fluorosilicone and an infrared-absorbing filler. At least 75% of the siloxane units in the fluorosilicone are fluorinated. Methods of manufacturing the imaging member and processes for variably lithographic printing using the imaging member are also disclosed.

An aqueous latex ink comprising a polystyrene copolymer latex, a co-solvent; and a colorant, which is suitable for use in an indirect printing method.

A sheet of elastomeric material that serves as a shock absorber and cushion for use between a flexographic printing plate and a printing cylinder during printing for compensating for variations in thickness, height and centricity of the printing cylinder and flexographic printing plate to prevent distortions in the image being printed that includes providing an elastomeric sheet having a longitudinal direction in the direction of circumferential travel of the cylinder circumference that includes a plurality or array of protrusions formed of the elastomeric material of predetermined cross-sectional shape and area and the material having a durometer to cushion the flexographic plate in such a way to provide the necessary compensation to ensure a high quality printed image at high speed. The cross-sectional shapes and the array of the longitudinal protrusions provide for material displacement zones that allows the elastomeric material to be compressed and return relatively instantaneously to its original height or near original height in sharing high quality printing compensating for tolerance errors between the drum size and the flexographic plate thicknesses.

An imaging member includes a surface layer comprising a fluoroelastomer-fluorosilicone composite. Methods of manufacturing the imaging member and processes for variable lithographic printing using the imaging member are also disclosed.

A method for treating a hydrophobic release layer of an intermediate transfer member for use in a printing process in which a negatively charged aqueous inkjet ink is jetted onto the surface of this layer. The method comprises contacting the release layer with a chemical agent which is an amine functionalized silicone. Transfer members comprising such a treated release layer and images printed therefrom are also disclosed.

The invention relates to a doctor or coater blade (1) of steel, having a nickel coating comprising abrasion resistant particles, said coating being constituted by an electrolytic nickel layer comprising abrasion resistant particles. The coating preferably comprises at least two electrolytic nickel layers having different composition, and may be formed differently in different sections of the blade. The invention also relates to a continuous process for electrolytic nickel coating in at least one electrolytic cell holding an electrolyte liquid comprising at least one nickel salt, and in at least one of these cells also comprising abrasion resistant particles.

A method for the formation of a luminescent layer having a uniform thickness in a desired pattern and an organic electroluminescent device that can realize high-quality display and is highly reliable. The luminescent layer is formed by providing a blanket having a resin film having a surface tension of not less than 35 dynes/cm as a surface layer and an ink for a luminescent layer, having a viscosity (ink temperature 23° C.) in the range of 5 to 200 cP as measured at a shear rate of 100/sec, and containing a solvent having a surface tension of not more than 40 dynes/cm and a boiling temperature in the range of 150 to 250° C., filling the ink into cells in a gravure form, allowing the blanket to receive the ink from the cells, and transferring the ink on the blanket onto a luminescent layer forming face.

The blanket cylinder for an intaglio printing machine comprising a plate cylinder carrying printing plates with engravings corresponding to a specific intaglio structure to be printed on a substrate, and cooperating with an impression cylinder, the blanket cylinder having at least one blanket on which the ink in the different colors is deposited by selector cylinders, each selector cylinder having reliefs with contours corresponding to the area of the intaglio structure to be inked with said color, the at least one blanket being made of several successive layers each with different properties.

An offset printing apparatus having a coated imaging member for use with phase-change inks, has a substrate, an optional intermediate layer, and thereover an outer coating with a nano-size filler having an average particle size of from about 1 to about 250 nanometers, and an optional heating member associated with the offset printing apparatus.
