FIELD: printing industry.
SUBSTANCE: device for printing of transient data in a sheet or web printing machine includes at least one magnetic system of image formation. The magnetic system of image formation is performed with the possibility to modify space configuration of magnetic fields during transition from one impression to another. In a specific case, the magnetic system of image formation is performed in the form of cylinder equipped with numerical disks with permanent magnets. The magnetic system of image formation may be performed in the form of a set of remotely-controlled magnetic heads or in the form of a set of remotely-controlled current buses.
EFFECT: provision of printing of a transient data on each subsequent sheet, increasing of protection level for printing products.
