    摘要： 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.

    摘要： 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.

    摘要： A negative-working imageable element has an imageable layer that includes an initiator composition including an iodonium cation and a borate anion, an infrared radiation absorbing compound, a particulate primary polymeric binder, and a phosphate (meth)acrylate adhesion promoter. The element also includes a polymeric overcoat disposed over the imageable layer and can be developed on-press to provide a lithographic printing plate with high run length. The element also has improved shelf-life.

    摘要： Negative-working imageable elements that can be imaged using infrared radiation comprise an imageable layer and a protective overcoat on a hydrophilic substrate. The imageable layer includes an IR-sensitive cyanine dye. The protective overcoat predominantly comprises one or more poly(vinyl alcohol) resins, each of which has a hydrolysis level of 85% or less. The use of this particular overcoat composition used in combination with the IR-sensitive cyanine dye provides improved tolerance to fogging by white light while maintaining desired imaging speed.
