摘要： A printed item contact member 54 according to the present invention includes: a base material 50; a fixing layer 52 that is formed on the surface of the base material 50 and substantially spherical particles 51 are fixed thereto; and a remarkably thin low-surface-tension coating layer 53 that covers the surface of the fixing layer 52 having the substantially spherical particles 51 fixed thereto and that exhibits release properties with respect to a printed item. The printed item contact member exhibits high ink repellency while maintaining the micro-uneven surface structure and is free from adhesion of yarn waste or dust to the member during cleaning, and therefore can be suitably used as, for example, a member for printing device in contact with the surface of printing paper.

摘要： 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. A coating formulation—which comprises fine particles of a thermoplastic resin having both a property that the particles unite to the surface when heated and a property that the particles decompose under action of the photocatalyst when exposed to activating light having energy higher than band gap energy of the photocatalyst—is applied as a hydrophobizing agent onto the surface. At least apart of the surface of the precursor is heated such that the fine particles applied on the part of the surface are fixed to form a hydrophobic image area. The fine particles applied on the remaining part of the surface with the image area formed thereon are then removed.

摘要： A printing press, and an apparatus and a process for regenerating a printing plate can repetitiously reuse the same printing plate and shorten time for decomposition of image areas formed by a hydrophobic organic compound under irradiation with activating light to delete the image areas. A process for regenerating a printing plate including a photosensitive layer, formed on the surface of a substrate, having a photocatalyst exhibits hydrophilicity responsive to activating light having energy higher than the photocatalyst's band-gap energy, and one or more hydrophobic image areas, formed on the surface of the photosensitive layer and operable to hold ink, comprises the steps of: removing ink remaining on the printing plate; hydrophilizing the surface of the printing plate by irradiating with the activating light and by heating the printing plate to delete the hydrophobic image areas; and applying an organic compound onto the printing plate.
