Temperature Sensitive Inks

Security inks that reveal a visible colour change when a selected temperature point is reached.

Overview

About Temperature Sensitive Inks

Temperature sensitive inks provide a clear visual response to heat, helping users authenticate products and confirm storage conditions. Formulations can produce reversible or irreversible colour changes at selected activation points from 5°C to 130°C. They are suitable for screen, flexo, and gravure printing and can be customized for different applications. Their resistance to abrasion and UV light supports lasting use on labels, packaging, and protected products. Additional covert security features can also be incorporated for layered authentication.
