I don't know if this works or not!!! I found this while researching the Glow in the Dark Powders for ResinObsession.
Mix Glow in the Dark Powder with printer ink, microwave it, (I don't know why you would need to do this), suck it up into a syringe, inject it into an empty printer ink cartridge. Once paper piece is printed turn off the lights and see your words glow in the dark.
Let me know if anyone tries this!
