(57)    Abstract

The invention discloses a device and a method for transferring a predeterminable, high-resolution magnetic design onto a document printed with magnetic ink, in particular magnetic optically variable ink. The device comprises a body of a composite permanent -magnetic material, having at least one flat or curved surface engraved with indicia corresponding to the design to be transferred, wherein the said magnetic material is permanently magnetized, preferably in a direction substantially perpendicular to the said surface. The method comprises imprinting or coating a first surface of a sheet or web with magnetic ink or coating composition, and approaching the imprinted sheet or web to the engraved surface of a body of magnetized composite permanent -magnetic material while the ink is wet, followed by hardening the ink.
