    Abstract: A plurality of negative-working lithographic printing plate precursors is provided in a stack. Each precursor comprises an aluminum-containing substrate having thereon a single imageable layer and an outermost topcoat that has a dry coating weight equal to or less than 1 g/m2. The non-imaging backside of the substrate is free of polymer coatings and has an average surface roughness (Ra) in both longitudinal and width directions greater than 0.15 μm. In addition, the imageable side of each underlying precursor is arranged in direct contact with the aluminum-containing substrate of the precursor above it without the use of an interleaf paper between the precursors.

    Abstract: A radiation-sensitive composition and negative-working imageable element includes a free radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of the free radically polymerizable component upon exposure to imaging radiation, a radiation absorbing compound, and particles of a poly(urethane-acrylic) hybrid that are distributed throughout the composition forming an imageable layer in the element. Imaging can be accomplished at a wide range of wavelengths from about 150 to about 1500 nm, and development can be accomplished using an organic solvent-based developer, warm water, plate cleaner, or on-press using a combination of a lithographic printing ink and a fountain solution.

    Abstract: Thermally imageable multilayer imageable elements useful as lithographic printing plate precursors that have good solvent resistance are disclosed. The underlayer of the imageable element comprises an acidic copolymer that comprises, in polymerized form, about 10 mol % to about 75 mol % of one or more monomers of the formula: CH2═CH(R1)-Z-X—NH—CO—NH—C6H3—(R2)(CO2H); in which: R1 is H or CH3; R2 is H or OH; Z is —C6H4— or —C(O) —Y—; Y is —O— or —NH—; and X is selected from —C(CH3)2—, —CH(CH3)— and —(CH2)n—, in which n is an integer from 1 to 12.

    Abstract: A method for forming a printing plate from a printing plate precursor having a radiation-sensitive layer, sensitive to radiation in a first frequency spectrum such as the far or near infrared, and to radiation in a second frequency spectrum other than the first frequency spectrum such as visible or ultraviolet. The plate is exposed twice. Once to imaging radiation in the first frequency spectrum and again to radiation in the second frequency spectrum. The second frequency spectrum exposure is done only to the areas of the plate undesirably shaded during the imagewise exposure.
