    Abstract: The present invention provides an imageable element including a lithographic substrate and an imageable layer disposed on the substrate. The imageable layer includes a radically polymerizable component, an initiator system capable of generating radicals sufficient to initiate a polymerization reaction upon exposure to imaging radiation, and a polymeric binder having a hydrophobic backbone and including constitutional units having a pendant group including a hydrophilic poly(alkylene oxide) segment. The imageable element can be developed using an aqueous developer solution. Alternatively, the imageable element can be developed on-press by contact with ink and/or fountain solution.

    Abstract: Thermally imageable elements comprising a masking layer and a substrate are disclosed. The masking layer contains a sulfated polymer or a mixture of sulfated polymers and absorbs both infrared and ultraviolet radiation. When the masking layer is on the substrate, the imageable element may be imaged and developed to form a photomask. When the imageable element additionally comprises a photosensitive layer, the masking layer may be imaged and developed to form an integral photomask. The imageable elements that comprise a photosensitive layer are useful as flexographic printing plate precursors.

    Abstract: Apparatus and method for exposing a lithographic printing plate wherein the apparatus includes a plurality of laser diodes emitting light of wavelength between 350 nm and 450 nm. The light from each of the laser diodes is directed onto the lithographic printing plate such that each spot on the lithographic printing plate receives light emitted from at least one of the laser diodes. Preferably, the lithographic printing plate is a violet-sensitive lithographic member and the lithographic member is a printing press plate. The power of each laser diode may be between 5 mW and 30 mW, and preferably the laser diodes emit light of wavelength between 390 nm and 430 nm.
