How is this possible? Photochromic Ink!
Just like the lyrics:
You come and go, you come and go
You come and go, you come and go
Photochromic inks are colourless when you come indoors . . .
. . . and vibrant colours when you go outside!
. . . and vibrant colours when you go outside!
This amazing effect works in combination with heat from the sun in addition to reacting to light.
SFXC sun sensitive coatings are perfect for screen printing. Our Photochromic Plastisol Ink is the ideal coating for making colour changing t-shirts. After applying plastisol, it needs to be heat cured to ensure it stays on your material.
What t-shirt design would you love to see revealed in the sun?
