<p>A printing press includes a dampening device (2), inking device (3), and fan roller (21,41,51). The dampening device (2) efficiently supplies dampening water to a plate mounted on a plate cylinder. The inking device (3) supplies ink to the plate mounted on the plate cylinder through an ink roller group (9). The fan roller (21,41,51) is arranged in the vicinity of the ink roller group (9) and driven to rotate. The fan roller (21,41,51) includes a pair of opposing wheels (22), an air intake port (26), and a plurality of vane members (27,42). The air intake port (26) is formed in at least one of the wheels (22). The first vane members (27) each have two ends fixed to the pair of wheels (22), and discharge air, taken in through the air intake port (26), in a radial direction of the fan roller (21,41,51) as the fan roller (21,41,51) rotates.</p> |
