  • A Lithographic Printing Plate Precursor
    Publication number: 20230382100
    Abstract: lithographic printing plate precursor including on a substrate which has a hydrophilic surface or which is provided with a hydrophilic layer, a coating comprising a photopolymerisable layer including a polymerisable compound, a photoinitiator and adhesion promoting compound containing at least one thiol group and at least one group capable of adhering to the substrate.

  • Lithographic Photopolymer Printing Plate Precursor with Improved Daylight Stability
    Publication number: 20230211599
    Abstract: A lithographic printing plate precursor is disclosed which comprises a support, a photopolymerizable image recording layer and an overcoat which comprises a low-molecular radical inhibitor. After image-wise exposure, the plate is heated whereby the radical inhibitor diffuses from the overcoat to the image recording layer, resulting in an increase of the daylight stability of the exposed and heated precursor. Such plate is especially suitable for on-press processing.

  • On-press processing of a UV or violet-sensitized lithographic printing plate
    Patent number: 11465404
    Abstract: A method of lithographic plate making is disclosed wherein a plate precursor is exposed to laser radiation in the wavelength range from 350 to 450 nm, said plate precursor comprising a hydrophilic support and a photopolymerizable or photocrosslinkable image recording layer, and then processed on-press by supplying fountain and ink. The exposure produces a visible image having a 1976 CIELAB color distance ?E between exposed and non-exposed areas of at least 2.5.
    Type: Grant

  • ON-PRESS PROCESSING OF A UV OR VIOLET-SENSITIZED LITHOGRAPHIC PRINTING PLATE
    Publication number: 20220032602
    Abstract: A method of lithographic plate making is disclosed wherein a plate precursor is exposed to laser radiation in the wavelength range from 350 to 450 nm, said plate precursor comprising a hydrophilic support and a photopolymerizable or photocrosslinkable image recording layer, and then processed on-press by supplying fountain and ink. The exposure produces a visible image having a 1976 CIELAB color distance AF between exposed and non-exposed areas of at least 2.5.
