1. A system for measuring the conductivity of a flexible media, comprising:
a conductive backing adapted to be positioned in contact with a first surface of the flexible media;
a conductive roller adapted to contact a second surface of the flexible media in a roller contact region when the flexible media is positioned between the conductive roller and the conductive backing;
a pressure control mechanism for pressing the conductive roller against the second surface of the flexible media with a specified contact pressure;
a motion control system adapted to provide a relative motion between the conductive roller and the flexible media;
a resistance measuring system electrically connected to the conductive roller and the conductive backing that measures an electrical resistance of the flexible media within the roller contact region; and
a data recording system for recording the measured resistance of the flexible media as a function of position as the motion control system provides the relative motion between the conductive roller and the flexible media.
