    • A web fed printing machine includes a web path provided between two sequentially disposed printing units and a misregistration detector for detecting misregistration in superimposition printing performed by the printing units. During superimposition printing, cylinder fine-move mechanisms finely move corresponding plate cylinders based on detected misregistration in order to adjust the registration. A web path length modification mechanism is provided in the web path. A control unit is connected to the web path length modification mechanism, the misregistration detector, and a paster. When a pasting signal is generated, the plate cylinder fine-move mechanisms stop making registration adjustment. At predetermined timing, the misregistration detector detects misregistration in printing performed by the printing units. The web path length modification mechanism performs a misregistration elimination action based on detected misregistration. Subsequently, the plate cylinder fine-move mechanisms resume making registration adjustment, and the web path length modification mechanism performs a return action.
    • 卷筒纸印刷机包括设置在两个顺序布置的打印单元之间的卷筒纸路径和用于检测由打印单元执行的叠加打印中的重合失调的对准检测器。 在叠加打印期间,为了调整配准,气瓶精细移动机构基于检测到的不对准而精细地移动相应的印版滚筒。 web路径长度修改机制在web路径中提供。 控制单元连接到卷筒纸路径长度修改机构,不对准检测器和贴片机。 当产生粘贴信号时,印版滚筒精细移动机构停止对准调整。 在预定定时,不对准检测器检测由打印单元进行的打印中的重合。 纸幅路径长度修正机构基于检测到的重合失调而进行排序不正确的动作。 随后,印版滚筒微移动机构恢复对准调整,并且卷筒纸路径长度修改机构执行返回动作。
