Abstract: A coating unit is located after a sheet-fed digital printer on a manufacturing line. As a response to a workpiece entering the coating unit from the printer, coating substance is dosed onto a plate cylinder, and said plate cylinder is rotated to transfer said coating substance onto the workpiece, which is then transferred further on the manufacturing line. As a response to a first time limit expiring after transferring the workpiece further without a subsequent workpiece entering the coating unit, the rotation of the plate cylinder is stopped.

Abstract: A system and method are provided for providing an improved inker unit surface cleaning and conditioning system, including in a single anilox chamber blade system, for improving image quality, including eliminating ghosting, in a proposed variable data digital lithographic image forming architecture. Techniques are provided to remove acquired oil from an inking member. A particularly-configured containment encloses a cleaner (disturber) roller to emulsify the acquired oil on the inking roller. The cleaner roller is preferably configured with a pliable surface including a silicon roller surface over a porous base. The silicon roller (1) absorbs dampening solution oil; and (2) agitates ink that may be still held in certain cells/cavities of the inking member or roller. In embodiments, a vacuum pressure is applied to the inside of the hollow cleaner roller to better remove the residual ink and dampening solution from the inking roller.

Abstract: The present disclosure is related to an apparatus for 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. Insoluble segments in the ink form a reversible gel that is broken to a liquid by heat and/or shear forces during the application process, allowing application of a liquid ink. After application, the ink reverts to its gel state with such strength as to allow overprinting in the wet on wet flexographic printing process. The disclosure is also related to a flexographic printing apparatus comprising a feeding system for providing a flexographic ink, wherein the ink in a liquid state has a viscosity ranging from about 100 cps to about 4,000 cps, and the ink in a gel state has a measurable hardness.

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. The insoluble segments form a reversible gel that is broken to a liquid by shear in the application process, allowing application of a liquid ink, and is reestablished in the applied ink film in such a manner and with such strength as to allow overprinting in the wet on wet flexographic printing process.
