ABSTRACT:
The printing machine has two interacting blanket cylinders (4, 14), between which the paper to be printed runs through, thereby being printed on both sides, two plate cylinders (5, 15), each of which carries a collect-printing plate and is in contact with one of the blanket cylinders, and two color-collecting cylinders (6, 16) which are arranged at a distance from one another and each of which is in contact with a plate cylinder (5, 15) and with several color selector cylinders (8, 18), each inked by an inking unit (9, 19). Moreover, the two blanket cylinders (4, 14) are each in contact with the plate cylinder (10, 20) of an additional printing unit which is a wet offset-printing unit working with a dampened intaglio printing plate. Thus, in one printing operation, banknotes can be produced, on the one hand, with a multi-color safety background according to the collect-printing process and, on the other hand, each with a single-color main design according to the wet offset-printing process, and furthermore the said intaglio printing plates can also have an additional background which is superposed on the multi-color background according to the collect-printing process.
