Speedball 047523 Night Printing Ink, Original, 8 fl. oz.

I used this to hand paint stars on sheets to make a fort. The stars glowed an amazing amount and even after being in a dark room all day they still were glowing a little. I will use again!

I do a lot of silk screening of our family and friends and have used this glow in the dark white for a couple years now; each time I am happy with the outcome. The ink drys a sort of greenish color and does glow in the dark a whitish-greenish color. I have used this on glow in the dark white on white, dark, orange, red and green cotton t-shirts and sweatshirts and have not had a problem with it at all. This bottom has been part of my colors for about 2, maybe 3, years now and still works well. Shake it up before using it to silk screen with, I get better results when I do this or stir it up before applying it to the item.

I grabbed this to make some patches for my band. Because we have to be the band that shows up with merch that's fancier than everyone else's we went with some glow ink.Easy to use, highly washable (don't worry about ruining your sink like with plastic inks!), doesn't add that annoying texture to your shirts/patches/whatever, and it glows BRIGHT! It looks sort of green-ish when it isn't glowing but it's unique looking. It might be ugly to some people but step under a black light or into a dark room and any thoughts of ugliness disappear instantly because this stuff looks GREAT when it lights up.One thing that I wasn't expecting but I love is that cleanup is way easier with this. Not sure if you've cleaned all the ink off your screen or out of your sink/tub? Hit the lights and spray down all those glowing spots! Cleanup gets way easier with this stuff!

This ink seems to glow really well but it's not very opaque, as seen in the first photo of a test print on an orange t-shirt scrap. (I'm not sure why attaching the pictures turned them sideways, they're right side up on my computer. One of the mysteries of Amazon, I guess.) This is the only reason I'm giving it four stars instead of five. The second photo shows the Night Glo ink printed on top of white ink, which works much better as far as normal, non-glowing visibility is concerned. The third photo shows how well the Night Glo ink glows by itself and the fourth shows the Night Glo on top of white ink combo and how it glows.This ink is also thinner than the Speedball white ink, but I didn't experience any problems in printing with it. I printed six shirts with it, the same design as in the photos.The ink reacts well using normal lighting, and glows faster and brighter when UV lights are used, like most other glow-in-the-dark products. It's a fun alternative to other normal colors and I may offer it as an option when I teach silk screen printing in my middle school art classes.

The glow in the dark does exactly that. Glows!

Not very dark better to use light background color first

Good quality screening ink. I liked another brand that I use to get at the local craft shop. They have not had it and I could not order it on line unless I was a store. Found this by accident and it is better than that other brand of ink. Now I now where to get my screening ink! Good quality stuff and the "glow" is really bright. Another good deal form Amazon!

Holy cow this stuff is amazing!! Really takes your shirts to the next level :) as mentioned in other comments it’s definitely best to put down a white base first because it’s more of a sheer color so it’ll glow great on its own but in normal lighting you won’t be able to see it very well
