Abstract
Device and process for producing indicia comprising magnetically oriented magnetic or magnetizable particles in ink or coating composition on a sheet of substrate material. Device includes a flat-bed screen-printing unit having a flat printing screen and a printing platen for receiving a sheet. Printing platen has an upper surface facing the printing screen and a first direction along its upper surface along which said sheet is unloadable, and a magnetic orienting unit having multiple magnet assemblies. Magnetic orienting unit is disposed below upper surface of the printing platen, the multiple magnet assemblies are disposed along first direction, and all of the magnet assemblies are concomitantly movable from a first position away from the upper surface of the printing platen to a second position close to the upper surface of the printing platen. The magnetic orienting unit having one or more magnet assemblies is usable as a stand-alone flat-bed magnetization device.
