  • Patent number: 11440312
    Abstract: Recess printing units are usable for printing on a substrate and using associated methods for operation. The recess printing units comprise an intaglio printing cylinder, which provides an image-forming pattern of recesses on its circumference; and an inking unit for applying ink to the pattern of recesses that are provided on the intaglio printing cylinder. The inking unit comprises a first inking unit cylinder which has, in a region of its lateral surface, recesses corresponding to the recesses in the intaglio printing cylinder and to which recesses ink can be supplied by an ink application device in the region of an application point lying on the circumference of the first inking unit cylinder.
    Type: Grant

  • Patent number: 8893614
    Abstract: There is described a device and method for magnetically transferring indicia to a coating composition, such as an ink or varnish, applied to at least a part of the surface of a substrate, the coating composition comprising at least one type of magnetic or magnetizable particles. The device comprises a body subjected to a magnetic field generated by appropriate electromagnetic means, which body carries determined indicia in the form of engravings on a surface of the body, which engravings influence orientation of field lines of the magnetic field. The body comprises at least one layer of material of high magnetic permeability in which the engravings are formed. In unengraved regions of the layer of material of high magnetic permeability, the field lines of the magnetic field extend substantially parallel to the surface of the body inside said layer of material of high magnetic permeability.

  • Patent number: 8813644
    Abstract: There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).
