Abstract:
1. An apparatus for orienting magnetic flakes in a fluid carrier printed on a substrate in a printing process, the apparatus comprising: a rotatable roller for positioning with an outer surface proximate to the substrate, said roller comprising a cylindrical body encased by a flexible magnetic sheet of a same magnetisable material having an even outer surface forming the outer surface of the rotatable roller, wherein the flexible magnetic sheet comprises one or more selectively magnetized portions surrounded by non-magnetised or differently magnetized portions thereof, said one or more selectively magnetized portions creating a magnetic field emanating from the outer surface of the roller so as to orient the magnetic flakes during the printing process in a selected pattern when the rotatable roller is positioned with an outer surface proximate to the substrate.
