Provided herein are compositions comprising substrates that contain polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects, and films or inks that contain ferromagnetic materials in which the films or the ferromagnetic materials are transparent. Also provided herein are methods of fabricating the substrates. Further provided herein are ferromagnetic material films containing transparent or translucent films that comprises ferromagnetic materials. The coating imparts functionality to the film such that the film is capable of being mechanically separated from the polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects using a commercial magnetic separator. The transparent, food-safe ink composition, which can be printed using high-speed flexographic, gravure, intaglio, offset printing or pad printing consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties.

The inkjet ink disclosed herein includes an inorganic solid portion including an inorganic pigment and glass and a monomer component having a photocurability. The ink is configured such that a volume of the inorganic solid portion when a total volume of the inkjet ink is 100 vol % is 30 vol % or less, and a volume of the glass when the total volume of the inorganic solid portion is 100 vol % is 78 vol % or more.
