Abstract
A device and a method using a printing device and system for printing sheets whereby, for each sheet, at least one register mark per color printing unit of the multi-color printing machine is produced, assigned to said sheet and defined with respect to its position, so that in duplex printing register marks are applied to each side. The position of each mark is determined by analyzing the position of the mark assigned to the appropriate previous recto or verso sheet.
