MagnaPrint® Glow FX is a ready-to-use, water-based printing paste, created by Magna for intense, glow-in-the-dark print effects. The product has no base colour so remains invisible under natural light, but when in the dark, the charged inks glow brightly in either green, light blue or aqua. This effect can even last up 15 minutes without additional exposure to natural or ultraviolet light.
