Multicolour rotary printing machine

Abstract

Abstract A convertible, multicolor, printing press for printing the safety background of banknotes or the like comprises, in one configuration, an impression cylinder, a second blanket cylinder which engages the impression cylinder, a first plate cylinder which engages the second blanket cylinder and also engages a first blanket cylinder which first blanket cylinder is spaced from the impression cylinder, and several sectioned inking rollers which engage the first blanket cylinder and which are each inked by inking devices of different colors. The printing press is converted to a second configuration by exchanging the sectioned inking rollers for second plate cylinders, separating the first plate and second blanket cylinders from engagement with the first blanket (11-14) and impression cylinders respectively, and moving the impression cylinder to directly engage the first blanket cylinder. In the one configuration, a juxtaposed color image may be printed and in the second configuration, a superposed color image may be printed.
