How does color change heat transfer vinyl work?

Color change heat transfer vinyl or UV Light Sensitive HTV work by absorbing UV Rays. So it changes color when exposed to sunlight.

This vinyl isn’t heat sensitive, as it does not change when you use your heat press to press.

Once you are out of the UV rays, colored areas become white again!

How do I press a design with color-change htv?

You can use EasyPress which is what I use normally on my HTV projects like t-shirts and other similar fabrics. I pressed at 300 degrees for 12 seconds. The instructions say that it is a warm peel but I let mine cool completely because when I tried to peel warm it began to lift.
