Patent ID: 8893614

Claim:
A device for magnetically transferring indicia to a layer of coating composition applied to at least a part of a surface of a substrate, said coating composition comprising at least one type of magnetic or magnetizable particles, said device comprising electromagnetic means for generating a magnetic field and a body subjected to the magnetic field generated by the 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, wherein said body comprises at least one layer of material of high magnetic permeability in which said engravings are formed and wherein, in unengraved regions of said layer of material of high magnetic permeability, the field lines of the magnetic field extend substantially parallel to the surface of said body inside said layer of material of high magnetic permeability, and wherein said body further comprises a base plate of material of low magnetic permeability supporting said layer of material of high magnetic permeability.
