ABSTRACT:
A color printing apparatus printing for both sides of a web of printing paper comprises a plurality of printing sections which are arranged at a regular interval in a piled configuration. Each one of the printing section includes a pair of blanket cylinders facing each other which can be moved between their contacting positions and their isolating position. Every blanket cylinder is connected to a plate cylinder which is connected to an inking unit, or an inking unit and a dampening unit. Each of the plate cylinders is further provided with a fine adjusting means for shifting the plate cylinder along its axis with respect to the blanket cylinder. The shifting operation of the fine adjusting means can easily minimize the printing shears caused by moisture without stopping the printing apparatus.
