PURPOSE:To enable a printing effect corresponding to three conventional printing presses to be obtained in a narrow machine installation space, by a construction wherein of six blanket cylinders, three pairs of adjacent blanket cylinders can be selectively moved. CONSTITUTION:Each of the blanket cylinders 11-16 can be selectively moved to the first position 11a-16a at which it makes contact with both an impression cylinder 1 and a plate cylinder 21-26 and the second position 11b-16b at which it makes contact with neither the impression cylinder 1 nor the plate cylinder 21-26. In addition, each of the blanket cylinders can be selectively moved to the third position at which the adjacent blanket cylinders in each pair make contact with each other and with the plate cylinder. With this arrangement, printing on one side of a web, perfect printing, monocolor printing and multicolor printing can be performed on two or three webs. |
