In a method and apparatus for generating a print image, particularly a franking imprint, on a first image carrier composed of at least one first partial image and a second partial image offset thereto transversely relative to a first direction, whereby a relative motion between a print head and an image carrier is generated along a first direction in a first step for generating the first partial image. A transverse offset between the print head and the image carrier is generated in a second direction proceeding transversely to the first direction in a second step. A relative motion between the print head and the image carrier is generated along the first direction in a third step for generating the second partial image. The waiting time interval between the end of the printing event of the first step and the beginning of the printing event of the third step has a length that is varied according to a prescribed function to prevent tampering.
