Method of manufacturing permanently magnetized elements
First Claim
1. A method of manufacturing a plurality of removable permanently magnetized elements from a substrate comprising ferrite material, the method comprising the steps of:
- (a) printing symbol images on the substrate with an offset, printing press,(b) die cutting the symbol images on the substrate to form a plurality of removable elements forming portions of the substrate, and(c) magnetizing the ferrite material to permanently magnetize the substrate and form the plurality of removable permanently magnetized elements.

Abstract
There is disclosed a method of manufacturing a plurality of removable permanently magnetized elements from a substrate comprising ferrite material. The method prints symbol images on the substrate with an offset, automatic sheet-fed press, and die cuts the symbol images on the substrate with an automatic sheet-fed die cutter to form a plurality of elements forming portions of the substrate. Thereafter, the method magnetizes the ferrite material to permanently magnetize the substrate and form the plurality of permanently magnetized elements. The method reduces wastage, permits for improved substrate registration, more accurate symbol placement on the substrate, higher production speeds, and reduced labor costs.
