ABSTRACT:
A continuously operative printing machine and a method of operating the same are disclosed. The printing machine has a plurality of switchable printing units to be used selectively by switching. For continuous printing the printing units are switched alternately by coupling and decoupling first coupling/decoupling means while a continuous printing web is held running. Plate change of stationary printing units is done with independent drive means to be ready for the next printing. Then the stationary printing units are restored to the printing state through synchronous control by rotational control means. Thus plate change printing or the like can be carried out continuously without stopping the printing machine. In addition, high quality printing can be obtained efficiently. Further, it is possible to obtain double side printing.
