  • Patent number: 8981254
    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.

  • Patent number: 8783179
    Abstract: Provided is a lithographic printing plate support that has excellent scratch resistance and is capable of obtaining a presensitized plate which exhibits excellent on-press developability and enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking ability after suspended printing. The lithographic printing plate support includes an aluminum plate, and an aluminum anodized film formed thereon and having micropores which extend in a depth direction of the anodized film from a surface of the anodized film opposite from the aluminum plate. Each micropore has a large-diameter portion which extends to a depth of 5 to 60 nm (depth A) from the anodized film surface, and a small-diameter portion which communicates with the bottom of the large-diameter portion, further extends to a depth of 900 to 2,000 nm from the communication position and has a predetermined average diameter.

  • 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.

  • Patent number: 8739701
    Abstract: The present invention pertains to a process and an apparatus for treating a photosensitive element to form a relief structure suitable for flexographic printing plate. The apparatus comprises an enclosure, a conveyor, a heatable roller with absorbent material conducted over it, and a roller that can significantly smooth or uniformly roughen the relief structure of the flexographic printing plate. Previously selectively cured photosensitive elements are developed by means of the heatable roller by blotting with the absorbent material, and the resulting relief structure is made uniform by way of a smoothing or roughening roller. The flexographic plates produced by the method and apparatus are especially suited to processes that require substantially smoothed or uniformly roughened printing plate surfaces, which are capable of producing better quality printing.
