PURPOSE:To enable a multi-color printing efficiently with one printing machine by providing a sub plate cylinder and an inking unit aside from the main plate cylinder to transfer ink onto one transfer cylinder from both the plate cylinders for multi-color printing. CONSTITUTION:A hose 7 to be printed is placed on an impression cylinder 8 and auxiliary rollers 9 and 10 and the impression cylinder 8 is lifted to press against a transfer cylinder 6. Then, receiving a black ink from an ink roller 13, the main plate cylinder 4 rotates counterclockwise with a motor 28 to transfer the name of maker or the like inscribed on the surface thereof onto a blanket 19 on the wheel body 20 side of the transfer cylinder 6. Then, as the transfer cylinder 6 rotates and extrudes a small piece 21 outward with a cam roller 26, a blanket 22 abuts against a sub plate cylinder 5 and standard dimensional designation and the like of the sub plate cylinder 5 receiving a red ink from the ink roller 13 are transferred onto the blanket 22 and then, onto the hose 7 separately with the rotation of the transfer cylinder 6. |
