Abstract
A thermal indicator using indicia formed by opaque ink applied to a thermal imaging material element is described. The ink is substantially the same color as the imaging element background and remains substantially hidden until the imaging element background changes color when heated. Time-temperature exposure indicating labels can be prepared using a printer with direct thermal type and ink jet type print heads.
