    Abstract: An imageable element can be imaged using non-ablative processes. This element has a non-silicone, non-crosslinked layer contiguous to and under an ink-repelling crosslinked silicone rubber layer. These elements can be used for providing lithographic printing plates useful for waterless printing (no fountain solution). Processing after imaging is relatively simple with either water or an aqueous solution consisting essentially of a surfactant or mechanical means to remove the crosslinked silicone rubber layer and a minor portion of the non-silicone, non-crosslinked layer in the imaged regions.

    Abstract: On-press development of an imaged printing plate on a plate cylinder, in which ink is applied by an ink form roll, a blanket roll is in contact with the plate, a rubber roll is opposed to the blanket roll, and printable media passes between the blanket roll and the rubber roll. The plate comprises a substrate carrying an imaged coating and nonimage areas. The respective cohesive and adhesive properties of the nonimage and image areas to the applied ink, substrate, blanket roll and printable medium, and the ink to the roll are such that the blanket roll pulls the ink from the plate and the ink pulls the nonimage areas from the substrate as undissolved particles that are transferred by the blanket with the ink to the printable media.

    Abstract: Negative lithographic printing plate having on a substrate a photosensitive layer comprising an alkaline soluble polymeric binder, an alkaline insoluble polymeric binder, a polymerizable monomer, and an initiator is described. The photosensitive layer is imagewise exposed with a radiation to cause hardening in the exposed areas, and then developed to remove the non-hardened areas. The combination of both alkaline soluble polymeric binder and alkaline insoluble polymeric binder in a photosensitive layer can give excellent combined durability, developability, and coatability.
