Above is an actual video of a set of Firefly ink cartridges for the Epson Workforce 1100 sitting on top of a sheet of Firefly™ paper that has been printed with an image sourced from the internet. In the video, we turn the lights on, then turn them off while a black light shines on the print and cartridges. The camera takes a moment to adjust.	In the above video we take a hand-held blacklight flashlight to show how the ink cartridges and the print can be made to glow. This particular printer is the Epson Workforce 1100. It is relatively inexpensive at $149, yet produces 13" wide output.

Firefly™ ink is a sophisticated encapsulated dye ink that is invisible in ordinary daylight. Turn off the lights and expose with a black light and the color is vibrant and life-like. We make Firefly inks in cyan, lt cyan, magenta, lt magenta, yellow and white. Because the inks are invisible and require UV light in order to be seen, images must be printed in a false color in order to appear normal under black light. We produced Firefly™ ink Image Converter software so you do not need to experiment. You can open an image, convert it and save it as jpg or png file to print in any software of your choosing. We also put in some expert tools for those who wish to experiment.

You may have seen invisible inks that glow under black light. But, you have never seen such bright and colorful invisible inks as Firefly™.
