    • PROBLEM TO BE SOLVED: To provide an original plate used for making a direct drawing type printing plate excellent in printing aptitude and in plate wear, realizing high resolution with a comparatively simple structure, by discharging and bonding an image forming liquid on the original plate for printing to form an image area directly thereon, its manufacturing method, and a plate making method for the direct drawing type printing plate using the direct drawing type original plate for printing.
      SOLUTION: A polyethylene terephthalate substrate 2, a protective layer 3 on the substrate 2, and an optical catalyst hydrophilic layer 4 are provided on the substrate 2, and further a dot controlling layer 5 having a critical surface tension not larger than the surface tension of an image forming liquid is provided on the hydrophilic layer 4 to obtain a direct drawing type printing plate 1. Further, after discharging the liquid for forming image with an ink jet recording head on a surface of the direct drawing type original plate for printing 1, the liquid is cured to obtain the direct drawing type printing plate.

    • PROBLEM TO BE SOLVED: To provide an original plate of an infrared-sensitive lithographic printing plate which has a sufficient mar resistance in all situations including transportation in the form of an interleaf-less package wherein the mar resistance is required. SOLUTION: The infrared-sensitive lithographic printing plate has a recording layer whereon an image can be formed by irradiation with infrared rays, on one side of a substrate, and has a back coat layer having a Vickers hardness of 0.2 or less on the side of the substrate opposite to the side having the recording layer. The recording layer preferably contains an infrared absorber. COPYRIGHT: (C)2007,JPO&INPIT

    • PURPOSE:To obtain a lithographic plate with a sufficient adhesion force with an ink repelling layer and an excellent printability by employing an iron material having a chrome-deposited layer exposing a crystal-like matter in the surface shape as support in a lithographic plate material eliminating a damping water. CONSTITUTION:A chrome-deposited layer is provided on an iron material made of pure iron or an iron alloy on an appropriate condition and exposes an angular crystal-like matter and/or an agglomerate thereof in the surface shape. The angular crystal-like matter can be a polygonal plate shaped one or hexahedral one and preferably, the projection area rate is more than 20% in the exposed portion. In addition, elements composing the surface side of the chrome-deposited layer shall be chromium and oxygen in substance and the element composition ratio of chromium and oxygen shall be uniform at the same depth and at any part of the surface. The support thus obtained is provided with a printing ink repelling layer made of an organopolysiloxane compound, polyfluoride compound or the like.
    • 目的:通过使用具有铬沉积层的铁材料将具有表面形状的晶状物质的铁材料作为支撑体去除平版印刷板材料,从而获得具有防油墨层的足够粘附力的平版印刷版和优异的可印刷性 一个阻尼水。 构成:在适当的条件下,在由纯铁或铁合金制成的铁材料上提供铬沉积层,并使表面形状的角结晶状物质和/或其结块露出。 角状晶体状物质可以是多边形板状或六面体状,优选在露出部分中的投影面积率大于20%。 此外,构成铬沉积层表面侧的元素应为物质中的铬和氧,铬和氧的元素组成比应在相同深度和表面的任何部分均匀。 由此获得的载体具有由有机聚硅氧烷化合物,多氟化合物等制成的印刷油墨排斥层。
