動が防止される。In such an apparatus, the attached roller 5 receives ink supply from the kneading roller 3 and rolls on the printing plate 9 placed on the plate plate al, thereby replenishing the plate 9 with ink. In conjunction with this movement, the blanket cylinder 6 moves between the plate surface plate 1 and the printing surface plate 2.
The ink on the plate 9 is transferred to the blanket 11, and the printing base Fj, 10 is further transferred again to perform printing. At the same time, the breath cylinder 7, which moves together with the blanket cylinder 6, is attached to the printing surface plate 2 side of the blanket cylinder 6, so it moves only on the printing substrate 10 placed on the printing surface plate 2, and the coating is coated immediately after printing. Press and smooth. In addition, press cylinder 7
The surface is covered with a resin that has poor wettability to prevent ink from adhering. The hairer pillow 12 is made of a flat metal plate, and as the bearers 13 and 14 roll on the bearer pillow 12, vibrations of the blanket cylinder 6 and press cylinder 7 are prevented.
