Method for orienting magnetic flakes

The invention relates to an apparatus (200) for orienting magnetic pigment flakes in a fluid carrier printed on a first side of a substrate (212) in a linear printing process. The apparatus comprises a magnetic structure (202,204,206,208) disposed proximate to a second side of the substrate, the mag...

Zusammenfassung:	The invention relates to an apparatus (200) for orienting magnetic pigment flakes in a fluid carrier printed on a first side of a substrate (212) in a linear printing process. The apparatus comprises a magnetic structure (202,204,206,208) disposed proximate to a second side of the substrate, the magnetic structure creating a selected magnetic field configuration to orient the magnetic pigment flakes to form an image.
