摘要： A method for producing a printable lithographic plate from a negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. Steps include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and blanket exposing the developed plate with a source of energy which further reacts the retained unreacted material in the image areas. A plate with a coating containing resin particles can be imaged to produce initial cross-linking, then mechanically developed. Hardening of the imaged areas is completed with a relatively intense post-heating at 160 deg. C., which further cross links the monomer and fuses the resin particles.

摘要： A method for preparing lithographic printing plates for on-press development, including sequentially feeding the plates to an imaging station to produce a plurality of latent image reference marks allocated among at least two margins along a respective two sides of the plate, and a latent print image within the margins. The imaged plates are transported from the imaging station to a plate bending station where the short ends of the plate are bent over. Between the imaging station and the bending station, the unimaged areas of the coating in at least two of the margins are removed to reveal the reference marks without developing the latent print image. Preferably, the reference marks are revealed while the plate is temporarily aligned in landscape orientation at stop, such as at the feeder to the bending station.

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.

摘要： Certain types of lithographic printing plates are activated by preheating while certain other types are post heated to harden the coating. A platen having a large mass compared to the mass of a printing plate is heated and maintained in the exact temperature range to which the printing plate is to be heated. A printing plate is brought into heat exchange contact with the platen for the period of time required to heat the printing plate to the temperature of the platen. The printing plate may be heated while resting in a fixed position on the platen or while the printing plate is carried over the platen by a continuous thin metal conveyor belt in intimate contact with both the platen and printing plate.

摘要： A metal substrate is treated with a plurality of rotating brushes and a slurry of particulate material such that the treated surface is capable of absorbing incident infrared laser radiation. The substrate is itself capable of being visibly imaged by selective writing with an infrared laser. The substrate is coated with an ablatable coating which is transparent to the imaging infrared laser radiation. Selective exposure to infrared laser radiation ablates this coating in the laser exposed areas as a result of the absorption of infrared radiation by the substrate. The substrate can be anodized after rotary brush graining and still retain its ability to be imaged and ablate a coating. The coated article can be imaged in a computer-to-plate infrared laser imaging device. Depending on the specific coating and substrate selection, the imaged article can be used in a conventional lithographic printing process or in a dryographic printing process.

摘要： A catalyst structure is formed by forging catalytic particles from a slurry into the surface of a metal substrate such that the particles protrude from the surface and are permanently fixed into the surface. The forging is accomplished by engaging rollers with the surface as it passes through the slurry to press the particles into the surface. The rollers may be brush rollers, fabric rollers or solid rollers. The particles may be any particles which have catalytic activity for a particular purpose and which are hard enough to forge into the metal substrate.

摘要： A positive-working, infrared imageable coating and a lithographic printing plate or other element with the coating are described. The coating is a phenolic resin containing an o-diazonaphthoquinone derivative which couples or reacts with the resin to partially insolubilize the coating and an infrared absorbing dye or pigment which further insolubilizes the coating and which renders the coating imageable by infrared radiation. The coating contains only that quantity of infrared radiation absorber necessary to be imageable and only that small quantity of o-diazonaphthoquinone derivative necessary to supplement the insolubilizing function of the absorber. Specifically, the absorber is from 1 to 10 weight percent of the total dry weight of the coating and the dry weight ratio of the absorber to the diazonaphthoquinone moiety is greater than 1:5 and preferably 1:2 or greater. By replacing a portion of expensive dye with some less expensive o-diazonaphthoquinone derivative to obtain the necessary degree of insolubility, the cost of the coating is greatly reduced.
