摘要： In this offset printing apparatus, a plate table (4) and a substrate table (6) are provided in a manner capable of traveling on guide rails (2) that are provided on a trestle (1). A transfer mechanism portion (9) that is provided with a blanket roll (10), lift actuators (13) of the blanket roll, a height sensor (14) of the blanket roll, and a pressure sensor (15) that detects the contact pressure of the blanket roll with respect to the plate (3) and the substrate (5) is provided at a position corresponding to the middle portion in the longitudinal direction of the guide rails (2). Also, a controller controls the lift actuators (13) so that the contact pressure that is detected by the pressure sensor (15) when the blanket roll (10) is brought into contact with the plate (3) and the substrate (5) becomes a predetermined value. Making uniform the contact pressure when performing transfer from the plate (3) to the blanket roll (10), and the contact pressure when performing retransfer from the blanket roll (10) to the substrate (5), makes the deformation amount of the contact portion with the plate (3) and the substrate (5) uniform, and equalizes the circumferential speed. As a result, it is possible to improve the printing accuracy.

摘要： An offset printing method of the present disclosure brings a blanket roller from above into contact with a plate held on a plate table traveling on guide rails on a mount, and then brings the blanket roller into contact with a print target held on a print target table traveling on the guide rails, to thereby perform transfer of a print pattern from the plate to the blanket roller and re-transfer of the print pattern from the blanket roller to the print target. The method further includes the steps of: causing a plate to be held on an alignment stage provided on an upper portion of the plate table and also causing a print target to be held on an alignment stage provided on an upper portion of the print target table; and correcting a position of the plate by the alignment stage of the plate table and also correcting a position of the print target by the alignment stage of the print target table.

摘要翻译： 本公开的胶版印刷方法使上方的橡皮布辊与保持在安装件上的导轨上行进的板台上的板接触，然后使橡皮布辊与保持在打印目标台上的打印目标接触 在导轨上行进，从而执行打印图案从印版转移到橡皮布辊并将打印图案从橡皮布辊重新传送到打印目标。 该方法还包括以下步骤：使板被保持在设置在平板台上部的对准台上，并且使得打印目标被保持在设置在打印目标台的上部的对准台上 ; 以及通过所述平板台的对准台校正所述板的位置，并且还通过所述打印目标台的对准台校正所述打印对象的位置。

摘要： An ink return blade 17, an ink filling blade 18, and an ink removal blade 19 are disposed in order at a retreat height that is higher by a predetermined dimension than the plate 10 retained in the plate table 11, and are supported by a supporting frame 20 at a predetermined position on a pedestal 8 of an offset printing apparatus. Separate elevating/lowering actuators 21, 22, 23 are provided for each blade 17, 18, 19. When the plate table 11 that retains the plate 10 is driven in one direction, after ink from an ink pool 25 on the plate 10 is filled into the plate 10 by the ink filling blade 18, and excess ink is removed by the ink removal blade 19. Therefore the plate 10 with a suitable amount of inking thereon can be supplied for printing operations. Thereafter, when the plate table 11 is driven in the opposite direction, the ink return blade 17 is brought into contact with the plate 10, and the ink pool 25 is returned to an initial position.
