A rotary press is operated slowly while paper is fed to the rotary press. A washing liquid is applied to the printing paper throughout substantially its entire width to wet the printing paper, and a plurality of guide rollers that are in contact with the travelling paper on the paper discharge side with respect to a printing portion are rotated at a peripheral speed different from that of the travelling paper so that contamination of the guide rollers is wiped off by the travelling paper. The washing apparatus of the invention has a plurality of guide roller driving devices which can drive and rotate the guide rollers at a peripheral speed different from that of the travelling paper.
