Abstract: Flexographic printing members are prepared from a flexographic printing plate precursor consisting essentially of: backing film, water- or water-dispersible photosensitive layer, and cover sheet in contact with the photosensitive layer. The cover sheet is removed and a mask element is laminated directly in contact with the photosensitive layer. Exposure through the mask element provides exposed regions and non-exposed regions. The non-exposed regions are removed with an aqueous developer having: a) a C12-20 saturated or unsaturated fatty acid (or alkali metal salt) at 0.25-2.0 weight %, and at least 85 weight % of a C18 mono- or poly-unsaturated fatty acid (or alkali metal salt); b) an aminopolycarboxylic acid (or alkali metal salt) at 0.05-0.30 weight %; c) a buffer at 05-0.60 weight %; and d) water. The photosensitive layer has a controlled release of 5-500 g/cm using ASTM D-3330 Method D, between its front imaging surface and the mask element.

Abstract: A method of making a relief image printing element from a photosensitive printing blank is provided. A photosensitive printing blank with a laser ablatable layer disposed on at least one photocurable layer is ablated with a laser to create an in situ mask. The printing blank is then exposed to at least one source of actinic radiation through the in situ mask to selectively cross link and cure portions of the photocurable layer. Diffusion of air into the at least one photocurable layer is limited during the exposing step and preferably at least one of the type, power and incident angle of illumination of the at least one source of actinic radiation is altered during the exposure step. The resulting relief image comprises a plurality of dots and a dot shape of the plurality of dots that provide optimal print performance on various substrates, including corrugated board.

Abstract: An imageable material can be used to form a mask image for providing a relief image. This imageable material has a simplified structure and consists essentially of, in order: a transparent polymeric carrier sheet and a barrier layer comprising a first infrared radiation absorbing compound. A first ultraviolet radiation absorbing compound is provided in the transparent polymeric carrier sheet or the barrier layer. A non-silver halide thermally sensitive imageable layer is disposed on the barrier layer and comprises a second infrared radiation absorbing compound and a second ultraviolet radiation absorbing compound. A relief image is formed by imaging the imageable material to form an imaged mask material, exposing a relief-forming material with curing radiation through the imaged mask material to form exposed regions and non-exposed regions, and developing the imaged relief-forming material to form a relief image by removing its non-exposed regions.
