PROBLEM TO BE SOLVED: To improve a printing quality without giving a change to a tension of a cooling roller by a load to a web and to improve a production efficiency. SOLUTION: This rotary press comprises variable speed motors 111 to 11, for independently driving cooling rollers corresponding to plate cylinders respectively provided at a plurality of printing units, and controllers 241 to 246 , for the motors for controlling rotations of the motors 111 and the like. Thus, since the cooling rollers are driven synchronously with the cylinders, a web tension is stabilized to prevent a deviation of a printing registering. |
