Thermochromic inks change their colour when exposed to different temperatures. Depending on the pigment they react at different heat. For instance, some need to be put in the oven and others can be just exposed to the sun to reveal the message. When cooled they change to the original state. This reversible effect allows multiple applications beyond promotional messages such as design effects o measuring tools.
Thermochromic inks can be used as promotional material, but also can be an indicator for serving a product at its optimum temperature (beverages, meds). In Food and Pharmaceutical markets and other chemical and biological areas these inks are commonly used.
