  • Patent number: 10821763
    Abstract: A method of roughening a surface of a printing form precursor. The method comprises subjecting at least a part of the surface to energy in the form of pulses of electromagnetic radiation to produce a uniformly hydrophilic roughened surface on at least a part of the printing form precursor and optionally converting the uniformly hydrophilic roughened surface of the printing form precursor to a uniformly hydrophobic roughened surface. The method is useful for providing a surface for use in a subsequent imaging and/or printing process in lithographic printing. Methods of providing a printing form comprising an image formed of hydrophobic regions and hydrophilic regions using said method and a method of printing using said method are also described, as are printing forms so produced and imaging devices and apparatus for carrying out the said methods.

    Abstract: A reimageable layer of an imaging member is provided with a dampening fluid layer. The reimageable layer has specific properties such as composition, surface profile, and so on so as to be well suited for receipt and carrying the dampening fluid layer. An optical patterning subsystem such as a scanned modulated laser patterns the dampening fluid layer. Ink having a first set of properties such as color, composition, etc., is applied at an inking subsystem such that it selectively resides in voids formed by the patterning subsystem in the dampening fluid layer to thereby form an inked latent image. The inked latent image is then transferred to a substrate, and the reimageable surface cleaned. The process is repeated for a second ink having properties different than the first. Each ink image may successively be applied to the substrate, or a composite image may be formed then applied to the substrate.

  • Patent number: 8785109
    Abstract: A method for producing a printable lithographic plate from a negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. Steps include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and blanket exposing the developed plate with a source of energy which further reacts the retained unreacted material in the image areas. A plate with a coating containing resin particles can be imaged to produce initial cross-linking, then mechanically developed. Hardening of the imaged areas is completed with a relatively intense post-heating at 160 deg. C., which further cross links the monomer and fuses the resin particles.
