    Abstract: An on-press ink and/or fountain solution developable lithographic printing plate comprising a photosensitive layer over an electrochemically grained, anodized, hydrophilically treated aluminum substrate with a reflection optical density of at least 0.30 is disclosed. The photosensitive layer is soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser having a wavelength of from 200 to 1200 nm. The plate is exposed with the laser off press or on press, and then on-press developed with ink and/or fountain solution. Such darker aluminum substrate in combination with the hydrophilic treatment allows fast press roll up, clean background, and good printing durability of the plate.

    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.
