摘要： A substrate is coated with a first material which is soluble in a first solvent, whereupon a second material which is strongly adherent to the first material and insoluble in the first solvent is selectively applied by an ink jet printer. The substrate is then developed in the first solvent to establish the image. In a preferred embodiment the substrate is hydrophilic, the first material is a negative working photosensitive material, and the second material is a transparent adhesive, which permits curing the first material by exposure to actinic light after the development step. The adhesive is then removed. In an embodiment directed to a waterless plate the substrate includes a surface coating of silicone, and the first material is a primer which promotes adhesion of a second material in the form of an oleophilic adhesive which is selectively applied. The primer is then developed to expose the silicone on the non-image areas. The ink carrying image areas are formed by the adhesive, which in this embodiment is not removed.

摘要： The water-loving properties of an anodized aluminum lithographic surface are enhanced or restored by treatment with a solution containing a monomeric, organo-phosphonic acid chelating compound or salt thereof. Such treatment can take place following, during or in lieu of the treatment of anodized aluminum in web form with an alkali metal silicate in the process of manufacturing printing plates. Alternatively, the treatment can be carried out as a plate is developed and/or prepared for the press. In a third approach, an organo-phosphonic acid chelating compound can be incorporated into a fountain solution, ink or correction fluid.

摘要： Smooth planar metal surfaces, usually an aluminum web, intended for a lithographic printing plate, are roughened by brush graining with fine abrasive particles which are hard and dense and have a radial or disk-like configuration such that the abrasive particles are forged into the surface of the metal forming cavities in which the abrasive particles remain embedded. The embedded abrasive particles are dislodged and removed from the cavities by subjecting the web to an anodic treatment employing electrolyte materials and concentrations, temperatures and voltage which will dislodge and remove the particles while retaining the surface texture or morphology of the as-roughened surface. The web is then subjected to a second anodic treatment under conditions which favor oxide formation in order to provide a final anodized product.
摘要翻译：用于平版印刷版的平滑的金属表面（通常为铝纤维网）通过用粗的和致密的细磨料颗粒进行刷磨而粗糙化，并且具有径向或盘状构造，使得磨料颗粒被锻造成表面的磨料颗粒保持嵌入其中的金属成形腔。嵌入的磨料颗粒通过使用电解质材料和浓度，温度和电压进行阳极处理而从空腔中移出并移除，其将移除和除去颗粒，同时保持粗糙表面的表面纹理或形态。然后在有利于氧化物形成的条件下对该网进行第二次阳极处理，以提供最终的阳极氧化产物。

摘要： Lithographic printing plates are made by exposing to actinic light a lithographic plate having a water soluble light sensitive layer thereon and a coating of a solvent soluble, UV curable material thereover to form an image in the light sensitive layer and adhere said layer to the overlying UV curable material. The plate is developed with water to remove light sensitive layer and overlying UV curable material in the non-image areas, and the plate is exposed to UV source having an intensity greater than the imaging light to form a press-ready plate having a durable, reinforced cured image thereon.
