Machine for security printing on security papers, especially bank notes, comprising a device (1) for feeding with paper, a device for transporting the paper and a unit (19) for applying optically variable images supported by at least one tape which is brought into contact with the paper such that these images are applied at defined locations on the paper corresponding to the printing marks on security papers. The application unit (19) includes at least one applicator cylinder (11) interacting with a pressure cylinder (20), the paper moving along between these cylinders. The tape is mounted between two reels arranged in a sector of the applicator cylinder (11) and the tape passes along a generatrix of said applicator cylinder, perpendicularly to the path of the paper, under the action of a servomotor acting intermittently at each application step.
