摘要： Negative-working and positive-working lithographic plate constructions include a durable hydrophilic layer; a hard, inorganic, oleophilic layer; and a substrate, which may be metal. If a metal substrate is employed, an overlying layer provides sufficient thermal insulation to prevent substantial dissipation of heat—which is necessary to achieve ablation—into the substrate. In the case of oleophilic layers employed in negative-working embodiments, certain ceramic materials are suitable, and an intermediate tying layer may be used to anchor a hydrophilic ceramic layer to the oleophilic layer. In positive-working embodiments, the oleophilic layers may be refractory compounds doped with oleophilic material. An advantage to the latter embodiments is the ability to apply traditional means of correction following imaging.

摘要： A method for imaging a printing form in which the printing form is charged on its entire surface and is coated on its entire surface with particles, in particular toner particles, which bear the opposite charge. The layer formed by the particles is then fixed in accordance with the image by a beam, in particular a laser beam, and especially by infrared radiation, on the surface of the printing form or ablated in accordance with the image. Thereupon, the unfixed portions of the layer are removed or the non-ablated portions are fixed by full-surface heat treatment.

摘要： The recording medium comprises a recording layer. The recording layer has a first material and a second material independently dispersed. The first material has a property that a backward contact angle to a liquid lowers when the material is heated in a state of being in contact with the liquid, and that the value of the backward contact angle recovers when heated in the air. The second material has a polyorgano-siloxane structure.

摘要： A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the image on the surface using an aqueous dispersion of an oligomer having in the molecule both hydrophilic and hydrophobic groups. The number of repeating units in the oligomer may be from 2 to 10 and the number of hydrophilic groups in the oligomer may also be from 2 to 10. Preferably the molecular weight of the oligomer is from about 500 to about 5000.
