摘要： A printing plate having a substrate and a radiation sensitive, negative working, organic, polymerizable, photosensitive (PS) resin coating non-ionically adhered to the substrate such that the cohesion of the PS coating exceeds the adhesion of the PS coating to the substrate. The PS coating contains active components that participate in radiation induced polymerization, all of which active components are soluble in non-aqueous solvents and none of which active components are soluble or dispersible in any of the group of fluids consisting of water, fountain solution, ink, and press ink. The PS coating has sufficient cohesion and surface tack to adhere to and be mechanically pulled off the substrate by press ink as particulates without dissolution or dispersion into the press ink.
摘要翻译：一种印刷版，其具有基底和辐射敏感的负性有机可聚合光敏（PS）树脂涂层，其非离子地粘合到基底上，使得PS涂层的内聚力超过PS涂层对基底的粘附。 PS涂层含有参与辐射诱导聚合的活性组分，所有这些活性组分都可溶于非水溶剂，而且活性组分都不溶于或分散在由水，润版液，油墨组成的任何一组流体中，并按墨。 PS涂层具有足够的内聚力和表面粘性以粘附并通过压榨油墨作为颗粒机械地从基材上脱落而不溶解或分散到压榨油墨中。

摘要： On-press development of an imaged printing plate on a plate cylinder, in which ink is applied by an ink form roll, a blanket roll is in contact with the plate, a rubber roll is opposed to the blanket roll, and printable media passes between the blanket roll and the rubber roll. The plate comprises a substrate carrying an imaged coating, in which nonimage areas have cohesion C1, adhesion to the substrate A1, and adhesion to the applied ink A3 and image areas have cohesion C2, adhesion to the substrate A2, and adhesion to the applied ink A4. The ink has cohesion C3 and adhesion A5 to the blanket roll. The nonimage areas have adhesion A6 to the printable medium and the ink has adhesion A7 to the medium. The adhesions and cohesions are such that the blanket roll pulls the ink from the plate and the ink pulls the nonimage areas from the substrate as undissolved particles that are transferred by the blanket with the ink to the printable media.

摘要： Disclosed herein are a method and apparatus for efficiently processing workpieces which are developed using a liquid developer. According to the invention a first set of workpieces is obtained from an imaging station, a second set of workpieces is obtained from a workpiece collection device, and the workpieces from the first and second sets are aligned in a contiguous arrangement, with the workpieces from the first set preferably being interspersed with those from the second set. Developer is then applied to the group of contiguous workpleces, thereby reducing the amount of overrun or overspray of developer that would otherwise result from individual processing of workpieces. The invention is particularly well-suited for use in preparing lithographic printing plates.

摘要： The invention relates to the application of a uniform film of a fluid to the surface of a flat workpiece as it is being conveyed through a workstation. The invention is specifically directed to the development of lithographic printing plates and comprises the application of the thin film of developer solution to each plate in a controlled manner using a wire-wound coating device and a unique manner of metering and feeding fresh fluid to the wire-wound device. Specifically, the fluid is gently fed onto the wire-wound device by simple volumetric displacement and overflow from the inside of a hollow tube onto the wire and the flow is controlled by sensing the beginning and end of each workpiece or plate. The hollow tube may be the wire-wound component or it may be a tube mounted above the wire-wound component. The spent developer is rinsed and sent to waste. According to the invention, only fresh developer solution is applied at a uniform film thickness, thereby achieving uniform image development.

摘要： A catalytic structure is formed by first partially embedding discrete, non-conductive particles into the surface of an aluminum substrate. Nodules of a catalyst metal are then electrodeposited onto the surface between the embedded particles. The non-conductive particles control the distribution of the electrodeposited nodules. The aluminum substrate may be anodized after embedding the particles and the particles themselves may possess catalytic activity thereby providing a dual catalyst structure.

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： According to the invention there is provided an electrochemical process for applying a firmly bonded insoluble metal oxide-organic complex on a metal surface by employing the metal as anode and a water-soluble poly basic organic acid as electrolyte together with a strong inorganic acid such as phosphoric acid or further admixed with another strong inorganic acid such as sulfuric. The polybasic acid may be a polyphosphonic acid, polyphosphoric and polycarboxyl acid, or polysulfonic acid and is advantageously polymeric. Polyvinyl phosphonic acid (PVPA) is a preferred electrolyte. Direct current is used. Pulsed plating may optionally be employed. The insoluble metal oxide-organic complex formed is composed of anodic oxide combined with polyacid, which forms a protective layer on the metal of improved corrosion resistance. The metal oxide-organic complex is well-suited to bond light sensitive coatings thereto. The metal may be steel or aluminum. The process is economical and the product novel.

摘要： Excellent development of photosensitive coatings on planographic printing plates is achieved by directing a dynamic flow of fresh alkaline developer solution that impinges on a target area of the coating extending the width of the plate and floods the target area with a turbulent flow. At sufficient volumetric flow rate, the developer solution at the target area is constantly displaced during the development time, whereby no boundary layer forms on and travels with the plate during the development time and thus the target area is always in contact with fresh developer solution.

摘要： A negative-working lithographic printing plate has a coating which is imaged by heating an area of the coating with an infrared laser and actinically reacting the coating in the heated area with ultraviolet or visible radiation. The coating contains an infrared absorber but the coating is not imageable by infrared radiation or by the heat generated. The imaging time is reduced since the actinic reaction rate is increased at the elevated temperature.
