Abstract

A printing machine comprising an indirect printing device, a drying device, a sheet transfer and turning device actuated according to requirements, and an intaglio printing machine. It permits printing in a single pass through the device a simultaneous recto-verso printing, namely on one side according to the color collecting printing method, an image with juxtaposed colors, and on the other side according to the offset printing method an image with superposed colors and designs, notably for creating safety background on bank notes, and after drying and, if necessary, turning the sheets, an image printed by intaglio printing on one of the sides, notably for creating a main design on the bank note. The multicolor printing on the side receiving the image with juxtaposed colors may be completed in the device by a monochrome wet offset printing. Moreover, a register control device is incorporated between the sheet transfer and turning device and the intaglio printing machine.
