A rotary intaglio printing machine has at least two printing mechanisms and a drying device arranged between the printing mechanisms, through which a web of paper to be printed upon successively passes. The printing mechanisms are so arranged that the web of paper is guided only by the plate cylinders and the impression cylinders of the printing mechanisms in a straight line from the preceding printing mechanism through the drying device in a contact-free mode to the following printing mechanism.
