摘要
PURPOSE:To prevent an ink from invading into an ink supply system for another ink via a pressplate therefor, by a method wherein a rotatable body is brought into contact with a transfer roller or an ink cylinder at the position just after it came into contact with the adjacent surface downstream of an ink supply order, and a doctor knife is abutted on the periphery of the rotating body at a position downstream in the rotating direction. CONSTITUTION:An ink-turbidity preventive device is so disposed that a rotating body 1 is in contact with either a transfer roller 7 or an ink cylinder 8. A doctor knife 5 is so disposed as to contact the periphery of the rotating body 1 at a position downstream of the contact point of the transfer roller 7 or the ink cylinder 8 in the rotating direction of the rotating body 1. A black ink transferred to the transfer roller 7 or the ink cylinder 8 provided with the ink-turbidity preventive device in an ink supply system SI of a supplementary printing device SP is transferred to and accepted by the rotating body 1 rotating in contact with the roller 7 or the ink cylinder 8, furthermore being scraped off from the surface of the rotating body by a doctor knife 5 due to the rotation of the rotating body 1 to be recovered into an ink-recovery pan 6.
