An electrochemical cell includes an anode and a cathode. The anode formed from a semi-conductive or conductive carbon-containing material is positioned adjacent to one of: the surface of the medium upon which the ink is printed, or the other surface of the medium. The cathode formed from a semi-conductive or conductive carbon-containing material is positioned adjacent to another of: the other surface of the medium, or the surface of the medium upon which the ink is printed.
