    • PURPOSE:To prevent a paper from being damaged and printing elements from being broken, by a method wherein intaglio printing element parts in two opposed intaglio plate surfaces formed of an elastic material are charged with an ink, a printing material is placed between the two intaglio plates,a nd perfect printing is conducted under a low pressure. CONSTITUTION:Ordinarily, a plastic is used as a material for the plate surface 1. When high accuracy is required, the plate is backed by a metallic plate 6. The elastic material preferably has a hardness measured by a Shore D type rubber hardness meter of about 30 deg.-80 deg., and the thickness of the elastic material layer is preferably not less than 100mum. In producing the plate surface, a polyure thane resin or a polyamide resin is suitably used from the viewpoint of durabil ity. To produce the plate surface, a duplicate plate having projected printing elements is produced on the basis of an original plate produced by engraving or etching, and the plate surface is produced on the basis of the duplicate plate by a casting method or the like. A printing ink may be an ordinary copperplate ink. The printing pressure may be much lower than that used in the case of a metallic plate surface.
    • 目的:为了防止纸被损坏并打印元件被破坏,通过由弹性材料形成的两个相对的凹版印版表面中的凹版印刷元件部件被填充墨的方法,将打印材料放置在两个凹版 在低压下进行完美印刷。 构成:通常,将塑料用作板表面1的材料1.当需要高精度时,板由金属板6支撑。弹性材料优选具有由肖氏D型橡胶硬度计测量的硬度 约30度-80度,弹性材料层的厚度优选不小于100微米。 在制造板表面时,从耐久性的观点出发,优选使用聚酯树脂或聚酰胺树脂。 为了制造板表面,基于通过雕刻或蚀刻制造的原版来制造具有投影印刷元件的复制板,并且通过铸造方法等在双面板的基础上制造板表面。 印刷油墨可以是普通的铜版印刷油墨。 印刷压力可能远低于在金属板表面的情况下使用的压力。

    • PURPOSE:To obtain the titled printing press capable of printing not only the front surface but also the back surface of a sheet, by making it possible to change over the rotation of a gravure printing roll in positive and reverse directions and providing a third roll in the direction opposite to a press roll through the printing roll in a spaced-apart state. CONSTITUTION:A gravure printing roll 1 is positively rotated and a doctor blade 10a is allowed to approach said printing roll 1 and a sheet 14 is passed to print the back surface thereof. The gravure printing roll 1 is reversely rotated and a doctor blade 10b is allowed to approach the gravure printing roll 1 while the sheet 14 is passed on the printing roll 1 through a free roll 13 and turned by a pressure roll 2 to also print the front surface of said sheet 14. By this method, not only the front surface but also the back surface of the sheet can be printed by one printing press.
    • 目的:为了获得能够不仅打印片材的前表面而且能够打印片材的标题的印刷机,可以通过使正面和反方向上的凹版印刷辊的旋转变化,并且提供第三辊 与印刷辊相反的方向以间隔开的状态穿过印刷辊。 构成:凹版印刷辊1被正转并且刮刀10a被允许接近所述印刷辊1并且片材14通过以印刷其后表面。 凹版印刷辊1反向旋转,并且允许刮刀10b接近凹版印刷辊1,同时片材14通过自由辊13在印刷辊1上通过,并通过压力辊2转动,还打印前面 通过这种方法,不仅可以通过一台印刷机印刷纸张的前表面而且还可以印刷纸张的后表面。
