    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: In a lithographic printing plate and method of manufacture, an interleaf is permanently integrated to the bottom surface of the plate substrate. A thin, flexible, water and solvent insoluble film is adhered to and covers the bottom surface of the coated and cured sheet before the sheet is cut into plates. The interleaf has a lesser thickness than the thickness of the substrate. A preferred method comprises the steps of selecting a wound coil of aluminum sheet, unwinding the coil and advancing the sheet through a coating station at which a liquid coating of radiation imageable material is applied to the top surface of the sheet, curing the material to form a cured coating adhered to the top surface of the sheet, laminating a polymeric film to the bottom surface of the sheet, and advancing the laminated sheet to a cutting device where individual plates are cut from the sheet.
