SYSTEMS FOR ERASING AN INK FROM A MEDIUM

摘要

A system for erasing an ink from a medium includes the medium having the ink printed on a surface thereof, and an erasure fluid directly or indirectly applied to the surface, wherein the medium further includes another surface opposed to the surface upon which the ink is printed. 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. The system further includes a power source to apply a voltage across the medium.

1. A system for erasing an ink from a medium, comprising:
the medium having the ink printed on a surface thereof, and an erasure fluid directly or indirectly applied to the surface, wherein the medium further includes an other surface opposed to the surface upon which the ink is printed; and an electrochemical cell, including:
an anode formed from a semi-conductive or conductive carbon-containing material, the anode being positioned adjacent to one of: the surface of the medium upon which the ink is printed, or the other surface of the medium;a cathode formed from a semi-conductive or conductive carbon-containing material, the cathode being positioned adjacent to an other of: the other surface of the medium, or the surface of the medium upon which the ink is printed; anda power source to apply a voltage across the medium.
