• A simple DIY alternative to screen printing powered by sunlight.

    Inkodye® develops its color in sunlight. It works on cotton, linen, silk, rayon, canvas, and any other natural & absorbent material.

    Once finished, your print is soft, permanent and can be machine washed without fading.

  • 1. Apply Inkodye
    Coat your shirt or fabric with sunlight-activated Inkodye in a dim environment.
  • 2. Block light
    Negatives or objects can be used to selectively block light from activating Inkodye. Make your own custom negatives through our app (not required).
  • 3. Expose
    Inkodye develops its color in sunlight or bright UV, about 10 to 20 minutes on a bright day.
  • 4. Peel
    Remove the negative in a dim environment to reveal your print. Almost done!
  • 5. Wash
    Using Inkowash, remove the unexposed dye to prevent it from further developing.
  • 6. Wear
    You're done! The print is now permanent and can be washed without special care.
