Thermochromic Screen Ink comes in:
These inks change color as their temperature changes. Our thermochromic inks all work the same way: below the activation temperature they are colored and above the activation temperature they are clear or lightly colored. As the ink cools, the original color returns.
Low Temperature: ink is used for applications in the refrigeration temperature range, like beverage labels and ice-cream packaging.
Body Temperature: ink is designed to show color at normal room temperature and to change when rubbed with the finger by breathing on it. It is used on packaging and other interactive products.
High Temperature: formulation changes color just below the pain threshold for skin, which is why it is a great safety feature on labels for microwaveable products and hot beverage labels.
In addition to our standard 15C, 31C (body-heat activated), and 45C temperatures, CTI can formulate custom temperatures between -5C and 65C upon request.
