Industry Info – Using Glow-in-the-Dark Ink

Whether it’s a bright, green cartoon on a child’s shirt or an eerie rock band’s brand on a hoodie, one of the coolest effects in screen printing is the use of glow-in-the-dark ink.

Let it Glow

Phosphorescent ink gets its luminosity from phosphors – a chemical that stores energy and radiates it out as a glow. Phosphors can be added to ink in a powder or you can buy ready-to-use glow-in-the-dark ink.

Printing Tips

  • Phosphorescent ink can be used on white and colored tees. If printing on a colored tee a white underbase will need to be used.
  • The more glow-in-the-dark powder used and the heavier the ink deposit, the longer the product will glow.
  • Most phosphorescent pigments will have a green glow, but some suggest adding fluorescent ink to change the hue. Glow-in-the-dark pigments can be produced in many colors. The human eye is however most sensitive to green light, meaning that green glow appears brighter and is generally favored by screen printers.
