Abstract: A substrate metal such as aluminum, usually in the form of a web, is anodized to form a porous oxide coating. A catalytic metal is then electrolytically deposited into the base of the pores preferably using an AC current. A portion of the oxide coating is then stripped away to expose the deposited catalytic metal at the surface of the remaining oxide layer. Alternately, a generally non-catalytic base metal may first be deposited followed by the deposition of the catalyst metal within the pores over the base metal. Further alternatives include stripping the oxide down to the base metal and then depositing the catalyst metal on the surface, further anodizing to form additional oxide between the deposited metal and the substrate, and enlarging the cross section of the base of the pores prior to the deposition of the metal.

Abstract: An elongated web of lithographic printing plate stock is intermittently fed to the drum of an external drum imaging device. The web is then cut to form the trailing end of an individual printing plate either before or after the leading end is clamped to the drum. The drum is then rotated such that the plate is wrapped around the drum and the trailing end is clamped to the drum.

Abstract: A lithographic printing plate or other coated imageable substrate is imaged by heating an area of the coating with an infrared laser and reacting the coating in the heated area with ultraviolet or visible radiation. The coating can be either positive working or negative working. The modulated radiation may either be the ultraviolet/visible radiation or the infrared radiation and the radiation spots are superimposed or the ultraviolet/visible spot may closely trail the infrared spot. The imaging time is reduced since the reaction rate is increased at the elevated temperature.

Abstract: A positive-working lithographic printing plate which is imageable by dual infrared lasers has a substrate which absorbs modulated, imaging infrared laser radiation of one wavelength to heat the substrate and an adjacent coating. The substrate has a coating which is a material which will react and form gaseous reaction products which ablate or propel the coating from the substrate upon reaching a threshold reaction temperature. The coating is transparent to the infrared radiation of the one wavelength and contains a dye which absorbs unmodulated, non-imaging infrared laser radiation of another wavelength to heat the coating. The unmodulated, non-imaging infrared laser radiation heats the coating in the imaged areas to a temperature below the threshold temperature and the heat from the substrate further heats the coating to a temperature above the threshold temperature and ablates the coating in the imaged areas.

Abstract: 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.

Abstract: Aluminum foil in the form of a continuous web for example, is anodically oxidized by first coating one side of the web with a material such as a polymeric material which is inert to the anodizing conditions and then electrolytically anodizing the uncoated side of the web. The laminate formed which can be used as a base plate for presensitized and wipe-on lithographic printing plates includes an aluminum foil coated on one side with an inert material and having an anodically oxidized layer on the other side which is formed after the one side is coated with the inert material.

Abstract: 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.

Abstract: 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.
