    Abstract: A device is disclosed for printing on blanks which are intended for swaging, to obtain a predeformed image on the blanks which, following swaging, will reconstitute the original image. The device comprises a light source (2), a toric prism (4) and a camera (8) having a common optical axis (12). The angle of the toric prism is smaller than 42.05.degree., and the surface (11) of the prism facing the camera (8) forms a linearity correction lens.
