Abstract
An ink supply system for a printer including an inner chamber comprising a controlled security ink; an outer chamber comprising a chemical; an ink conduit from the inner chamber through and out of the outer chamber; and a rupture wall at a junction between the inner chamber and the outer chamber. The ink conduit keeps the chemical away from the ink when the ink travels from the inner chamber out of the ink supply system. When the rupture wall is ruptured, the chemical is adapted to interact with the controlled security ink to indicate that the rupture has occurred.
