Thermochromic ink indicia for activatable quality labels

An activatable quality label operative to provide an indication of exceedance of a temperature threshold following activation thereof at a temperature less than or equal to an activation temperature, comprising:

• a readable indicator located on said quality label and operative, following activation of said quality label at or below said activation temperature, to readably indicate exceedance of said temperature threshold;
• an actuator element operative to activate said readable indicator on said quality label after preconditioning of said quality label, the actuator element including an actuator indicator indicating a precondition temperature is satisfied;
• and
• indicia at least partially formed by thermochromic ink, said indicia formed on said actuator element, said thermochromic ink having a first visual appearance at temperatures less than or equal to said activation temperature and a second visual appearance at temperatures above said activation temperature, such that a visual appearance of said indicia is indicative of whether said quality label is at a temperature less than or equal to said activation temperature and hence may be activated.
