Abstract: A negative-working lithographic printing plate precursor is disclosed that can be developed on the press without going through a development processing step, and a method of lithographic printing is also disclosed that uses this negative-working lithographic printing plate precursor. A negative-working lithographic printing plate precursor is provided that exhibits excellent on-press developability, nonimage area fine line reproducibility and printing durability and that resists the production of scum during on-press development. The negative-working lithographic printing plate precursor has a hydrophilic support and has thereon a photopolymerizable layer that contains at least one selected from the group consisting of a polymer compound that has an ethylenically unsaturated bond in the side chain position, a hydrophilic group and a sulfonamide group and a polymer compound that has an ethylenically unsaturated bond in the side chain position, a hydrophilic group and a cyclic structure derived from a maleimide. The method of lithographic printing uses this negative-working lithographic printing plate precursor.

Abstract: Negative lithographic printing plate having on a substrate a photosensitive layer comprising an alkaline soluble polymeric binder, an alkaline insoluble polymeric binder, a polymerizable monomer, and an initiator is described. The photosensitive layer is imagewise exposed with a radiation to cause hardening in the exposed areas, and then developed to remove the non-hardened areas. The combination of both alkaline soluble polymeric binder and alkaline insoluble polymeric binder in a photosensitive layer can give excellent combined durability, developability, and coatability.

Abstract: A method of forming visible image on an on-press developable lithographic printing plate is described. The plate comprises on a substrate a photosensitive layer developable with ink and/or fountain solution and capable of hardening upon exposure to a radiation. The plate is imagewise exposed with a radiation, overall treated with a discoloring agent to form visible image or enhanced visible image, and then on-press developed with ink and/or fountain solution. The formation of visible image allows easy identification or inspection of the plate by the pressman before mounting on press.

Abstract: A method of deactivating an on-press ink and/or fountain solution developable lithographic printing plate is described. The printing member comprises on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser. The plate is exposed with a laser, deactivated, and then on-press developed with ink and/or fountain solution. The deactivation is carried out by overall applying to the plate a deactivating agent, heat, or a radiation that has different wavelength from the laser and does not cause hardening of the photosensitive layer. The deactivation allows the plate to be handled on press under white light or other light that is unsafe for a non-deactivated plate.
