    • A method of exchanging printing units at a running rotary printing press, wherein a first printing unit is withdrawn from the printing medium, and a second printing unit for printing the same image with the same register is set against the printing medium, includes the steps of applying to the printing cylinder of the second printing unit, prior to start of the printing operation, a register printing block elevated relative to the regular printing block; prior to changeover of the printing units, setting the second printing unit against the printing medium such that register marks print with the register printing block without an image printing with the regular printing block; detecting register marks and adjusting the second printing unit register by reference to the detected register mark; and with the register adjusted, exchanging the printing units by withdrawing the first printing unit and setting the second printing unit.
    • 一种在运行中的旋转印刷机上更换印刷单元的方法,其中第一印刷单元从打印介质中取出,并且相对于打印介质设置用于使用相同寄存器打印相同图像的第二打印单元,包括以下步骤: 在打印操作开始之前,向第二打印单元的打印滚筒施加相对于普通打印块升高的对准打印块; 在打印单元的切换之前,将第二打印单元设置在打印介质上,使得对准标记用寄存器打印块打印而不用普通打印块进行图像打印; 通过参考检测到的对准标记来检测对准标记并调整第二打印单元寄存器; 并且通过调整寄存器,通过撤回第一打印单元并设置第二打印单元来更换打印单元。
