    摘要: A method of exchanging printing units at a running rotary printing press, wherein a first printing unit is withdrawn from the printing medium, and a second printing unit for printing the same image with the same register is set against the printing medium, includes the steps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.
