Shuuichi Nagahata has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Coating formulation for printing plate precursor, printing plate precursor, printing press, fabrication process of printing plate, and regeneration process of printing Plate
    Publication number: 20060144271
    Abstract: Disclosed are a printing plate precursor, a fabrication process of the printing plate precursor, a fabrication process of a printing plate, a regeneration process of the printing plate, a printing press, and a coating formulation for the printing plate precursor. According to the present invention, a printing plate can be fabricated directly from digital data, and sufficient image quality can be obtained without a developing step, i.e., a developer. To permit repeated use of the precursor, the precursor has a surface, which contains a photocatalyst and is capable of showing hydrophilicity when exposed to activating light having energy higher than band gap energy of the photocatalyst.
    Type: Application
    Filed: February 28, 2006
    Publication date: July 6, 2006
    Applicants: MITSUBISHI HEAVY INDUSTRIES, LTD., MIKUNI COLOR LTD.
    Inventors: Yasuharu Suda, Hiroshi Tonegawa, Minoru Sueda, Hideaki Sakurai, Yoshiyuki Tasaka, Yosuhiro Akita, Toyoshi Ohto, Kimihiko Ohya, Shuuichi Nagahata
