    Abstract: Negative-working lithographic printing plate precursor a negative-working imageable layer and an outermost water-soluble overcoat layer that is disposed directly on the negative-working imageable layer. The outermost water-soluble overcoat layer comprises: (1) one or more film-forming water-soluble polymeric binders, (2) organic wax particles, and (3) non-wax matte particles. The outermost water-soluble overcoat layer has a dry thickness (t) that is defined by the following equation (I): t=w/r wherein w is the dry coverage of the outermost water-soluble overcoat layer in g/m2, and r is 1 g/cm3. The organic wax particles have an average largest dimension D(wax) that is less than 0.9 of t (in μm), and the non-wax matte particles have an average largest dimension D(matte) that defined by the following equation (II): 1.5 times t≦D(matte)≦40 times t (in μm).

    Abstract: Lithographic printing plates are provided by imagewise exposing negative-working lithographic printing plate precursors having a negative-working radiation-sensitive imageable layer, followed by contacting with a processing solution that has a pH of at least 7 and up to and including 11. This processing solution also includes component (1) that is a nitrogen-containing base having an atmospheric pressure melting point of at least 40° C.; component (2) that is a non-ionic surfactant that independently has an atmospheric pressure melting point, glass transition temperature, or pour point of at least 40° C.; component (3) that is a hydroxy-containing solution promoter; and component (4) that is a hydrophilic surface protective compound. The method is carried out in a manner such that the exposed and processed precursor is not further treated with any liquid (such as gumming or rinsing solution) between processing and mounting onto a printing press.
