  • Patent number: 10946686
    Abstract: An intermediate roller positioned between a fountain solution vapor supply and an imaging member decouples fountain solution vapor deposition from the surface of the imaging member. The intermediate roller may be temperature controlled. A uniform layer of fountain solution condenses onto the surface of the temperature controlled intermediate roller regardless of the imaging blanket temperature. The fountain solution condensate layer deposited onto the intermediate roller splits and deposits a thin uniform layer of fountain solution liquid onto the imaging member surface. This liquid layer split may be independent of the temperature of the imaging member surface, resulting in a uniform layer of fountain solution on the imaging blanket for better imaging quality. Remotely locating the vaporizing chamber away from the imaging member prevents undesired heat transfer from a hot vaporizing chamber/baffle to the imaging member surface.

  • Patent number: 10336057
    Abstract: An apparatus and method for printing directly onto print media including smooth non-absorbent media substrates (e.g., polymer films) inks having a wide range in viscosity, so that flexographic, gravure, and lithographic inks can all be contemplated. The proposed method is able to print with variable data/imaging. Dampening fluid may be patterned onto an imaging roll by coating the imaging roll with a layer of the dampening fluid and selectively evaporating off a patterned portion via a laser imaging device. The imaging roll then contacts the print substrate and transfers the patterned dampening fluid onto the substrate via film splitting. The substrate then passes through an inker station where ink is deposited directly to the substrate for attachment thereto except where rejected by the dampening fluid.

    Abstract: In a method for re-imaging a printing form that has been used for printing in a prior printing process a substrate of the printing form is cleaned globally of ink or varnish and the substrate is treated abrasively globally in order to erase a preceding printing image. The substrate to be imaged with a new printing image is treated locally in image regions with a pulsed laser beam and, in the process, a nanoscopic and hydrophobic surface structure is produced locally. The substrate is treated globally with a hydrophilicity intensifier, as a result of which the substrate becomes hydrophilic locally in the previously hydrophobic image regions. An apparatus has a corresponding erasing unit and an imaging unit with a femtosecond laser.

  • Publication number: 20140318397
    Abstract: A system and method are provided for optimizing a multi-color variable digital data lithographic image forming system by controlling characteristics of one or more individual color inks to maximize ink transfer of a particular color ink layer onto the surface of an image receiving medium substrate, or onto other color ink layers deposited on the surface of the image receiving medium substrate when producing digital output images, including multi-color digital output images, with a proposed variable digital offset lithographic architecture. Ink characteristics and ink transfer parameters are particularly optimized in the proposed variable digital data lithographic systems to promote high efficiency ink transfer from an ink donor surface to an ink receiver surface in order that excessive amounts of untransferred ink do not remain on the ink donor surface requiring extensive cleaning of the reimageable surface in the image forming system between cycles of a multi-color ink system.

  • Patent number: 8869698
    Abstract: Apparatus and methods for transferring a principal substance to a substrate involve the use of a gating agent that blocks the substance from or attracts the substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the gating agent directly to the substrate or to an intermediate surface. The substance may be an ink, an electrically conductive material, a magnetic material, a carrier for a therapeutic, diagnostic, or marking substance other than an ink, or a carrier for any other type of substance.

  • Patent number: 8833257
    Abstract: Systems and methods for high-speed variable printing are provided. Ink jet technology and lithographic systems may be combined in such a way to create a fully variable and high-quality print system. At least one area of a plate is reserved for variable information to be printed. The plate may already comprises static information to be printed. Ink is then applied to the at least one area of the plate reserved for the variable information. An aqueous solution is applied to a web to produce a negative image of the variable information, and a positive image of the variable information is transferred in ink to the web. The systems and methods described herein may be used to create high-quality one-to-one marketing applications.

  • Publication number: 20140251167
    Abstract: A method and apparatus for transferring a principal substance applies the principal substance onto a surface and deposits drops of a gating agent onto a first portion of the principal substance applied to the first surface. The depositing of each drop of gating agent is individually controlled. A second portion of the principal substance not covered by the gating agent is transferred from the first surface to a second surface. A printing system adapted to transfer principal substance from a first surface to a second surface is also disclosed, wherein the printing system exerts mechanical pressure between the first surface and the second surface.

  • Patent number: 8807029
    Abstract: Embodiments of the present invention dispense with the need for lithographic printing plates, instead facilitating direct transfer of ink from a permanent cylinder to a recording medium. Accordingly, instead of being permanently modified to exhibit oleophilic and oleophobic (or hydrophilic) regions, the cylinder is effectively “programmed” with the image prior to each transfer of ink.

  • Publication number: 20140216286
    Abstract: Provided are web-offset lithographic ink compositions that contain an alkyl thioether surfactant, an alkoxylated modified rosin, or a combination thereof. The ink compositions can be oil-based inks or water-based inks that can be radiation-curable. The resulting ink compositions can be used in web-offset lithographic printing to substantially reduce or eliminate the ink feedback and ink build-up that occurs during printing. Also provided are methods for reducing or eliminating ink feedback and build-up during lithographic printing processes.
