Abstract

A customizable temperature exposure indicator and methods for making the same are disclosed. The temperature exposure indicator includes a substrate, a printing region of the substrate forming a heat sensitive media that is configured to darken when it is heated by a thermal printhead, the darkening being permanent with respect to subsequent cooling of the media; at least one memory thermochromic composition provided on an indicator region of the substrate, the thermochromic composition is configured to have high temperature color state when it is heated above a high temperature threshold, and to remain in the high temperature color state until it is cooled below a low temperature threshold, the thermochromic composition is configured to have a low temperature color state when it is cooled below the low temperature threshold and to maintain the low temperature threshold until it is heated above the high temperature threshold.
