ABSTRACT:
One or more arrays of heating elements are configured with insulating regions to prevent the dissipation of heat to unintended regions of a thermochromic substrate. Methods include printing and arranging impressions on a two-sided substrate avoiding bleeding and other problems more-commonly associated with traditional two-sided thermal printing techniques. A simple and reliable thermal printing system is provided for use in ballot marking, including several mechanisms for receiving and detecting the orientation of a substrate within a thermal printing apparatus.
