Abstract
The invention concerns a device for magnetically transferring indicia, such as a design or an image, to a wet coating layer applied on a substrate, such as a sheet or a web, wherein the said coating layer comprises at least one type of magnetic or magnetizable particles; said device comprising a) at least one magnetized permanent-magnetic plate () carrying relief, engravings or cut-outs, mounted such that its relief surface remains accessible, b) at least one additional magnet (), disposed below said at least one permanent-magnetic plate, facing the surface of the magnetic plate which is opposite to the relief, engraving or cut-out, and c) a holder (), which has the mechanical function to hold the pieces together in fixed positions. A method for producing the device, the use of the device, and magnetically induced designs obtained with the device, which are useful for protecting currency, value—and identity documents, are disclosed as well.
