  • Publication number: 20100288144
    Abstract: The invention relates to a printing method by an offset printing press and an offset printing press by which a substrate process is carried out for low-whiteness printing paper such as paper for newspaper with aqueous substrate treatment agent so that the print quality can be improved. In the invention, in order to suppress occurrence of a curl of printing paper, substrate treatment agent containing solid fine particles and a binder component is supplied to a printing face of printing paper, and the substrate treatment agent is dried to form a porous layer having a great number of holes having a smaller diameter than that of pigment contained in printing ink from the solid fine particles and the binder resin. Then, offset printing is carried out on the printing paper.

  • Publication number: 20100212523
    Abstract: 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.

  • Patent number: 6978715
    Abstract: 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.

  • Patent number: 6851364
    Abstract: A printing plate material which can be adapted to digitization of the printing process and recycled and a method for renewing it. As the printing plate material, there can be used one which includes a substrate on the surface of which a coat layer containing a titanium oxide photocatalyst and at least one member selected from salts or oxides of Fe2+, Ni2+, Mn2+, Cr3+, and Cu2+ is formed. In an initial state of the printing plate as prepared, it is adjusted to a state where the surface of the coat layer is hydrophobic. This surface is irradiated with ultraviolet rays to convert a part of the surface to a hydrophilic surface. This conversion is performed based on digital data corresponding to an image to be printed. In this case, the hydrophobic portion is used as a printing image portion and the hydrophilic portion is used as a non-printing image portion.
