Thermochromic: Heat-Activated Screen Printing
Thermochromic coatings change color in response to temperature fluctuations. There are two primary types of thermochromic coatings: liquid crystals and leuco dyes.
The most famous application ever, the “mood” ring of the 1970s, was a liquid crystal. Thermochromic coatings are ideal for use on consumer packaging, product labels, security printing, advertising, and novelty applications such as temperature sensitive plastics and mugs, promotional items, toys, and textiles.
Most often, we find our clients engage us to apply the thermochromic coating in a solid color that disappears when exposed to temperature change, revealing the image underneath.
