    • PROBLEM TO BE SOLVED: To provide an offset printing device capable of performing high accuracy fine printing, preventing the deterioration of printing accuracy and lowering manufacturing costs without causing the deterioration of productivity.SOLUTION: The offset printing device 100 includes a doctor blade 5, a blanket roll 15, a plate attachment surface plate 25, a print plate 60 disposed on the plate attachment surface plate 25, and a print surface plate 35. The print plate 60 and the print surface plate 35 are disposed at a predetermined inclination angle for the print advancing direction. The doctor blade 5 is disposed so as not to be in parallel with the print plate 60. A film 40 is supplied so as to be in parallel with or orthogonal to the print surface plate 35 so that a pattern is printed in parallel with the film 40.
    • 要解决的问题:提供能够进行高精度精细打印的胶版印刷装置,防止印刷精度的劣化并降低制造成本,而不会导致生产率的劣化。 解决方案:胶版印刷装置100包括刮刀5,橡皮布辊15,印版附接表面板25,设置在印版附着表面板25上的印版60和印刷表面板35。 板60和打印表面板35以预定的倾斜角度设置在打印前进方向上。 刮刀5设置成不与印刷板60平行。薄膜40被提供成与印刷表面板35平行或垂直于印刷表面板35,使得图案与薄膜平行地印刷 (C)2012年,JPO&INPIT

    • PROBLEM TO BE SOLVED: To improve printing accuracy by enhancing the geometrical reproducibility of printing patterns.SOLUTION: By forming a transferring device for offset printing 18 though the provision of a portal frame 21 so as to be athwart guide rails 13 provided on a treastle 12, the attachment of each of right and left bearing housings 28a and 28b for rotatably retaining the rotating shaft 30 of a blanket roll 19 with a roll supporting frame 27 to the columns 23a, 23b, 23c and 23d of a frame 21 through vertically direct-acting guides and further the attachment of the nut members 36 of a ball-screw mechanism 33 to each of the bearing housings 28a and 28b at the execution of transferring and re-transferring by thrusting the blanket roll 19 from above with the required contact pressure against a plate 14 on a plate table 15 or against a printing object 16 of a printing object table 17 running on the guide rails 13, the possibility of the development of deformation in mechanical structural parts except in the blanket roll 19 by the reaction of the contact pressure of the blanket roll is suppressed.
    • 要解决的问题:通过提高打印图案的几何重现性来提高打印精度。解决方案:通过形成用于胶版印刷18的转印装置,尽管提供了门架21,以便设置在防水板12上的偏转导轨13 左右的轴承座28a,28b各自的安装用于通过垂直方向直线地将框架21的支柱23a,23b,23c和23d的辊23a,23b,23c和23d的辊支撑框架27可旋转地保持在橡皮布辊19的旋转轴30上, 通过将所需的接触压力从上方推压橡皮布卷19,执行转印和再转印,从而将滚珠丝杠机构33的螺母部件36连接到每个轴承座28a和28b上。 在台板15上的板14或与在导轨13上运行的打印对象台17的打印对象16相对应,机械结构中变形的可能性 通过橡皮布辊的接触压力的反应,除了橡皮布辊19之外的结构部件被抑制。
