Abstract: This disclosure is directed to a plate design for use in variable data digital lithographic image forming devices. The disclosed plate design incorporates surface passivated carbon black filler material particles in a fluorosilicone polymer. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles surface passivated via the use of an A/B-block copolymer where the A/B block contains a pentafluorostyrene-maleimide alternating polymer and the B block contains pure pentafluorostyrene. The A/B portion allows for the polymer to adsorb onto the carbon black while the b-block acts as the stabilizer in fluorinated systems. Fine dispersions result from the addition of poly (pentafluorostyrene/Maleimide-b-pentafluorostyrene) or P(PFS/MI-b-PFS) passivated carbon black to fluorinated polymers, enhancing the physical and mechanical properties.

Abstract: The invention refers to a flexographic printing process with wet on wet capability based on controlled polymer or polymer segment precipitation that leads to gel formation of ink compounds by controlling the solubility parameter of the ink system. The mechanism to obtain a desirable wet on wet color trapping is the formation and/or presence of a gel in the applied ink film due to a controlled physicochemical mechanism of resin precipitation. This is accomplished either by controlling a change in the Hansen Solubility Parameter of the liquid in the ink through evaporation of some or all of a non-reactive and volatile solvent, or alternatively by use of a polymer comprised of two distinct and separate segments one of which is soluble in the monomer/oligomer mix and the other of which is not.

Abstract: A method of transferring an image to an article is provided using a heat-transfer assembly having a support layer and an image transfer layer, wherein the image transfer layer contains a binder, ink receptor and a film-forming, hydrophilic blocking agent. When an aqueous ink composition is used to print an image on the upper surface of the transfer assembly, the blocking agent is disrupted in the imaged areas, but not the unimaged areas, such that when the image is transferred to a substrate by the application of heat and pressure, substantially all of the binder in the unimaged areas remains with the transfer assembly.

Abstract: A photopolymer plate manufacturing process utilizes a modified substrate and mask to generate pre-cut and interchangeable single and multi-part stamp dies. Using a modified substrate and mask, a conventional photopolymer plate can be manufactured with a plurality of independent pattern or stamp areas that are readily removable and replaceable on the substrate and do not require cutting. The resulting material is also securable to a plastic stamp or the like without an adhesive, thereby facilitating a stamp with exchangeable patterns. Additionally, with a further modified mask, the stamp dies can be manufactured in two or more separable pieces, which can then be selectively interchanged among multiple stamp dies. An alignment tool facilitates installation of the stamp dies on the stamp mechanism.

Abstract: A lithographic precursor includes a hydrophilic layer that presents a surface for lithographic interaction, and which is formulated to receive a pigment-based aqueous ink deposited (e.g., by inkjet) in an “imagewise” pattern. The compatibility between the ink and the hydrophilic layer is such that a baking step is not required for subsequent printing.

Abstract: A method for producing a structured surface making contact with printing material, preferably a cylinder cover, includes producing a structured coating having microparticles on a substrate, preferably a stainless steel plate. The microparticles are encased antiadhesively and agglomerated by adsorption of nanoparticles, and the agglomerates being produced are fixed in a sol-gel matrix. A surface produced in this way has a structured coating on a substrate and the coating has microparticles. The coating has agglomerates fixed in a sol-gel matrix and including microparticles encased antiadhesively by adsorption of nanoparticles and preferably formed of silicon carbide. The surfaces advantageously have a self-repair function since, in the case of abrasion of structural elevations, the antiadhesive casings of the microparticles are exposed and the antiadhesive property of the coating is maintained.

Abstract: A method is disclosed in the context of a system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed. This negative image is then transferred to the reimageable surface. The negative image is then developed with ink. The inked image may be transferred to a substrate.
