Abstract
There is provided a surface treatment device of a printing press that does not cause adverse affect on a transfer film in the surface treatment device at a quick stop of the printing press. The transfer film is wound around a plurality of rollers in the surface treatment device, and rollers disposed close to an impression cylinder out of the plurality of rollers are adapted to be capable of being individually driven through motors, respectively. At an emergency stop of the printing press, a controlling section fine-adjusts the running speed of the transfer film into synchronization with the speed of the impression cylinder, by driving the rollers individually while acquiring information from an impression cylinder encoder.
