Patent number: 9229325Abstract: Lithographic printing plate are formed by imagewise exposing a positive-working lithographic printing plate precursor with infrared radiation to form an imaged precursor comprising exposed regions and non-exposed regions, and processing the imaged precursor to remove the exposed regions using a processing solution having a pH of 12 or more, that contains a metal cation M2+ selected from barium, calcium, strontium, and zinc cations, and is substantially silicate-free. The positive-working lithographic printing plate precursor comprises a grained and anodized aluminum-containing substrate, a first ink receptive layer comprising at least one water-insoluble, alkali solution-soluble or -dispersible first resin, a second ink receptive layer disposed over the first receptive layer, and an infrared radiation absorber in an amount of at least 0.5 weight %, in either or both of the first ink receptive layer and the second ink receptive layer.Type: GrantFiled: February 25, 2014Date of Patent: January 5, 2016Assignee: EASTMAN KODAK COMPANYInventors: Celin Savariar-Hauck, Gerhard Hauck, Domenico Balbinot, Andrea Pauls

Publication number: 20120141941Abstract: Imaged lithographic printing plates are processed using a developer that is replenished with only water, but replenishment is at a rate to allow developer volume to slowly decrease from a developer reservoir. This allows for a longer processing cycle especially when the developer is supplied from a container having a defined amount and applied using spray devices where water evaporation from the developer can be significant. Water lost by evaporation is replenished while water carried out by lithographic printing plates is not replenished.Type: ApplicationFiled: December 3, 2010Publication date: June 7, 2012Inventors: Mathias Jarek, Domenico Balbinot, Harald Baumann
