    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. Also disclosed are a negative-working lithographic printing plate precursor that can be developed by a water-soluble resin-containing aqueous solution and a method of lithographic printing that uses this negative-working lithographic printing plate precursor. A negative-working lithographic printing plate precursor is provided that exhibits an excellent fine line reproducibility in nonimage areas even when printing is performed using ultraviolet-curing ink (UV ink). Also provided is a negative-working lithographic printing plate precursor that exhibits an excellent combination of 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 support and has thereon a photopolymerizable layer that contains a polymer compound that has the urea bond in the main chain and a hydrophilic group and a carboxylic acid content less than 0.05 meq/g. The method of lithographic printing uses this negative-working lithographic printing plate precursor.

    Abstract: A method of processing an on-press developable lithographic printing plate with ink and/or fountain solution is described. The plate comprises on a substrate a photosensitive layer which is either capable of hardening (negative-working) or solubilization (positive-working) upon exposure to a laser, the non-hardened or solubilized areas of the photosensitive layer being soluble or dispersible in ink and/or fountain solution. The plate is exposed with a laser, heated to an elevated temperature, and then developed with ink and/or fountain solution on a lithographic press. The laser exposed plate is preferably heated by passing through a heating device or while mounted on a lithographic press before on-press development.
