Ink with pigment that glows after being charged with light. We have two options for glow-in-the-dark printing. The traditional glow ink has a slight green tint in regular light and glows a pale green. The second option is a bright white ink that glows blue. We like to think of it as a surprise glow since you can’t tell it glows until you’re in the dark. Both inks must be printed on top of white to achieve the full effect, and they also work with any type of garment.
