ROTARY MULTICOLOR PRINTING MACHINE FOR SIMULTANEOUS RECTO-VERSO PRINTING ABSTRACT The printing machine has two interacting blanket cylinders (1,2) which are each inked by several offset plate cylinders (5,12) and between which the paper (P) to be printed on both sides runs through. One of the blanket cylinders (2) is also in contact with a plate cylinder (8) carrying a collect printing plate which is inked in a multicolor manner by a further blanket cylinder (9). This blanket cylinder (9) receives the inks from several appro- priately inked selective color inking cylinders (10). Also arranged between the two blanket cylinders (2,9), which are in contact with the plate cylinder (8) carrying the collect printing plate, is an adjustable and convert- ible plate cylinder (16) which, in a first working position, carries an offset plate and rests against the blanket cylinder (2) inked by the offset plate cylinders (12), whilst in a second working position it carries a selective color inking plate and rests against the blanket cylinder (9) inked by the selective color inking cylinders (10). Thus, it is possible to produce on one side of the paper a multicolor pattern which is made by means of two differ- ent printing processes and in which either the number of colors used in collect printing or the number of colors used in offset printing is selectively increased by one color.
