摘要： Method for making lithographic aluminum offset printing plates according to the DTR-process by photo-exposing a photosensitive monosheet layer assemblage comprising a hydrophilic aluminum foil, an intermediate layer comprising hydrophobic polymer beads prepared by polymerization of ethylenically unsaturated monomer(s) and having an average diameter not lower than 0.2 .mu.m, and a silver halide emulsion layer, applying an aqueous alkaline solution to the photo-exposed silver halide emulsion layer in the presence of a developing agent and a silver halide solvent to form a silver image and to allow unreduced silver halide or complexes formed thereof to diffuse image-wise from the developed silver halide emulsion layer to said aluminum foil to produce thereon a silver image, and separating said emulsion layer and said intermediate layer from the imaged aluminum foil. The invention also relates to the photosensitive monosheet layer assemblage used for making such printing plates.

摘要： A halftone dot image pattern is formed on a support comprising a paper base, a polyolefin layer on at least one side of said paper base in a coverage in the range of 5 to 40 g/m2, on the opposite side of the polyolefin layer a binder layer comprising a hydrophilic colloid binding agent and white titanium dioxide pigment particles having an average grain size in the range of 200 nm to 450 nm, said pigment particles being present in a coverage of at least 0.5 g per m2 up to 300% by wt of the total binder contents. The half tone dot image pattern is on the exterior side of the binder layer and is a halftone relief image pattern having at least color pigmented gelatin-containing layer, preferably three or four such layers of different colors; e.g., cyan, magenta, yellow and optionally black. The resultant halftone material has a controlled visual appearance; e.g., for color proofing purposes, especially with respect to dot gain.

摘要： A process for forming a line art of halftone multicolor colloid pattern involves the contact exposure in registration of different colored silver halide emulsion hydrophilic colloid layers each on a temporary support and the hardening development of the individual exposed silver halide emulsion layers in turn after each is transferred to a common intermediate support to form thereon a multi-layer assembly of reverse reading color relief images on top of each other. This assembly together with an underlying stripping layer from the intermediate support is transferred bodily onto a permanent support by adherence to an adhesive layer carried on the latter support to form thereon a right-reading multicolor image that may serve as a color proof.

摘要： Sheet material including a cellulose acetate temporary support carrying thereon a continuous strippable layer. The strippable layer is a non-photosensitive layer containing a coverage of at most 20 g/m.sup.2 gelatin hardened to a degree corresponding to the addition of at least 0.001 g of formaldehyde per g of gelatin. Transfer of the strippable layer from the temporary support onto an image material having e.g. an imaged hydrophilic colloid layer or relief pattern given improved gloss control and optical dot gain control for such image material.

摘要： Process for controlling the visual appearance of an image present on a permanent support in the form of a hydrophilic colloid layer, layer system or relief pattern by the transfer of a continuous non-photosensitive layer from a temporary support onto said permanent support either before or after said image is formed thereon, which comprise by pre-wetting the permanent support either image-free or with said image already thereon, containing the pre-wetted support with said continuous layer carried on the temporary support, and stripping off the temporary support to leave the continuous layer adhering on the permanent support, said continuous layer being non-photosensitive and contains hardened gelatin, the gelatin being applied at a coverage of at most 20 g/m2 and having a degree of hardening corresponding with that achieved by the addition of at least 0.001 g of formaldehyde per gram of gelatin.
