  • Patent number: 11787167
    Abstract: Ink-based digital printing systems useful for ink printing include a secondary roller having a rotatable reimageable surface layer configured to receive fountain solution. The fountain solution layer is patterned on the secondary roller and then partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate. To achieve a very high-resolution (e.g., 1200-dpi, over 900-dpi) print with these secondary roller configurations, an equivalent very high-resolution fountain solution image needs to be transferred from the secondary roller onto the imaging blanket. To increase the resolution of the image on the secondary roller, examples include a textured surface layer added to the secondary roller for contact angle pinning the fountain solution on the roll. Approaches to introduce a micro-structure onto the surface layer of the secondary roller, and also superoleophobic surface coatings are described.

  • Patent number: 11691435
    Abstract: A method and system for enabling a patterned liquid, can involve creating a heat image on an imaging blanket by selectively heating the imaging blanket with a digitally controlled energy source, and subjecting the heat image to a selective deposition of a fountain solution material to enable vapor condensation on unheated areas and vapor rejection from heated areas to generate a fountain material image.

  • Patent number: 10737483
    Abstract: In a digital inking system having an anilox member that carries a patterned metered layer of ink to a digital imaging member, and a doctor blade that removes excess ink from the surface of the anilox member resulting in the patterned metered layer, an overfill form roller in rolling contact with the anilox member adds an overcoat layer of ink on the patterned metered layer for transfer of both layers of ink to the digital imaging member. The overcoat layer of ink uniformly covers all regions of the anilox member and the mattered metered layer of ink, including lands of the anilox cell walls to make the combined layers of ink pattern-free.

  • Patent number: 10589515
    Abstract: A variable lithographic cleaning apparatus, system and method works on the principle that dust and ink residue may be transferred from a lower surface energy reimageable conformable blanket surface to a higher surface energy surface low durometer cleaning member, such as the tacky roller, and then to an even higher surface energy cleaning member, such as the hard roller, which is hard and robust to scratching. The hard roller can then been scrubbed clean by an ink flushing device having a third cleaning member, such as a melamine sponge, wetted with a cleaning solution with the hard roller dried upon each rotation.

  • Patent number: 10471752
    Abstract: A chamber blade system maximizes ink flow at an anilox doctor blade by including a heating element adjacent the doctor blade to heat ink adjacent the blade. The heating element may be a heat strip next to an anilox doctor blade that heats the ink adjacent the doctor blade and temporarily reduces the ink viscosity to improve the flow of ink in the vicinity of the blade. Doctoring blades with a ceramic tip coating may be configured to allow a small amount of controlled ink flow through that can wet the lands thereby reducing the hydrodynamic back pressures and friction when trying to force the ink into anilox cells.

  • Patent number: 9507266
    Abstract: A system and method are provided for enclosing a plurality of cleaning unit components in a moist cleaning unit environment, the plurality of cleaning unit components cooperating to employ a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A range of solvents may be applied to a hard smooth high surface energy surface of the cleaner roll and a cleaning unit component internally positioned within the cleaning enclosure to clean the surface of the cleaner roll. Mechanical components are properly placed prior to the cleaner roll-reimageable surface nip to ensure that residual liquid on a surface of the cleaner roll is removed.

  • Patent number: 9272506
    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.

  • Patent number: 9272532
    Abstract: Forming an imaging blanket for a printing apparatus includes depositing a patternable material over a substrate, etching the patternable material according to a desired exposure pattern, hardening the etched patternable material to thereby form a template surface comprising a desired template pattern of texture features, depositing a layer of curable liquid polymer over and in physical contact with the template surface, curing the liquid polymer to thereby form the imaging blanket, and removing the imaging blanket from the template surface to thereby expose a patterned imaging surface of the imaging blanket. The image blanket may thereby be provided with a desired texture surface, for example comprised of individual molded image blanket features, such as recesses or pillars, of a desired cross-sectional shape. The image blanket is configured for and may be disposed on an image forming member of a variable data lithography system.
