    Abstract: The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; a method of preparing the photosensitive element to form a printing form for use in relief printing; and, a process of making the photosensitive element. The printing form precursor includes a layer of a photosensitive composition, a digital layer that is adjacent to a side of the photosensitive layer, and a cell pattern layer that is disposed between the photosensitive layer and the digital layer. The cell pattern layer includes a plurality of features, and is composed of an ink that is opaque to actinic radiation and transparent to infrared radiation. Since the cell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer.

Each coupler includes a wall connected to the support structure, which defines a cavity for receiving a microduct on the support structure first side. Each coupler removably retains the microduct within the cavity and provides a seal between the wall and microduct. A port adapter has a base unit, a hinged cover, at least one cable port, and support structure with multiple couplers that receive and removably retain microducts. A microduct coupling panel has multiple couplers connected to a planar frame in a grid arrangement. A perimeter of the panel can removably couple with a corresponding coupling portion of at least one of a terminal enclosure and a port adaptor.

    Abstract: An aqueous ink for ink jet including a resin particle. The resin particle has a first layer and a second layer in this order from the inside toward the outside of the resin particle. The first layer is formed of a first resin in which the proportion of a unit derived from a cycloaliphatic-group-containing ethylenically unsaturated monomer is 10% by mass or less. The tetrahydrofuran-insoluble fraction of the second layer is 15% by mass or more. The second layer is formed of a second resin having the unit derived from the cycloaliphatic-group-containing ethylenically unsaturated monomer and a unit derived from an ionic-group-containing ethylenically unsaturated monomer. The proportion of the unit derived from the ionic-group-containing ethylenically unsaturated monomer in the second resin is 3% by mass or more to 70% by mass or less.

  • Patent number: 9962974
    Abstract: This disclosure is directed to more effectively prevent blocking. An inkjet printing apparatus 100 has a platen 3, an after-heater 4, a take-up gear 5, and a cooler. The platen 3 heats a medium 20 to a temperature lower than or equal to a glass-transition temperature Tg1 of a resin included in the medium 20. The after-heater 4 heats the medium 20 to a temperature higher than or equal to a glass-transition temperature Tg2 of a resin contained in the ink. The take-up gear 5 collects the printed medium 20. The medium 20 or the take-up gear 5 is cooled by the cooler so as to reach a temperature lower than both the temperature Tg1 and the temperature Tg2.

  • Patent number: 9747532
    Abstract: An application of clear protectant to a printable medium is described that allows for different amounts of protectant to be applied to the medium based on the amounts of colorant that is applied to the medium. Colorant bitmaps are analyzed to calculate an amount of colorant coverage for a medium. Printable features in the colorant bitmaps are replicated into different intermediate protectant bitmaps based on the colorant coverage for the printable features, where the intermediate protectant bitmaps specify different amounts of protectant to apply. Features in the intermediate bitmaps are expanded and replicated into a final protectant bitmap. A determination is made for the amount of protectant to apply to the medium that is based on the different amounts specified by the intermediate bitmaps.
