  • 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.

  • Publication number: 20190281002
    Abstract: E-mail synchronization may involve synchronization of data types, such as a unique identifier (UID), flag, header, and content. Upon identifying a trigger (e.g., user input) to receive a plurality of messages, a client device an implement an optimized retrieval scheme. This retrieval scheme may involve retrieval of multiple data types (e.g., UIDs, flag(s), and text) for one group of messages before those data types are retrieved for other groups of messages. Retrieval schemes can be determined and dynamically adjusted based on user input so as to provide quicker retrieval of certain data of certain messages. Retrieval schemes can also be optimized when multiple mailboxes are present.

  • Publication number: 20190255833
    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.

  • Publication number: 20180056645
    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: 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.

  • 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.
