Color-changing inks are specially formulated inks that change from a clear state to a vibrant color when exposed to ultraviolet (UV) sunlight. All of our clothing products use a combination of standard screen printing inks and our special sun-activated inks to provide the maximum color-change effect.

There is a slight "clear shade color" when our sun-activated ink is applied to a t-shirt. The "clear shade color" is barely visible when the t-shirt is not exposed to sunlight.

The sun-activated color appears in 10 seconds or less, depending on the sunlight intensity, and fades to a clear color when removed from sunlight.
