  • Zirconia ceramic lithographic printing plate
    Patent number: 5870956
    Abstract: Lithographic printing is carried out by a novel process utilizing a zirconia ceramic as a printing plate. In this process, the surface of the zirconia ceramic printing plate is imagewise exposed to radiation which transforms it from a hydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. The zirconia ceramic printing plate utilized in this process is capable of extremely long printing runs, is especially well adapted for direct digital laser imaging using images that are electronically captured and digitally stored, and can be reused by erasing the image from the ceramic surface by thermally-activated oxidation or laser-assisted oxidation.
    Type: Grant
    Filed: July 23, 1997
    Date of Patent: February 16, 1999
    Assignee: Eastman Kodak Company
    Inventors: Syamal Kumar Ghosh, Dilip Kumar Chatterjee, Donald Michael Korn, Nicoletta Assaro Zongrone, Mark Anthony Harris
