This ink seems to glow very well but is not very opaque as shown in the first photo of the test print on an orange t-shirt patch. (I'm not sure why the attached images are turned sideways, they are right side up on my computer. I think that's one of Revain's secrets.) That's the only reason I'm giving it four stars instead of five. . The second photo shows Night Glo ink printed over white ink, which performs much better when it comes to normal non-luminous visibility. The third photo shows how well the Night Glo ink glows alone, and the fourth photo shows Night Glo on the white ink combo and how it glows. This ink is also thinner than the Speedball's white ink, but I didn't notice that. There are no problems with printing. I printed six t-shirts with the same design as the photos. The ink responds well to normal lighting and glows faster and brighter when using UV lamps like most other glow-in-the-dark products. It's a fun alternative to the other regular colors, and I might suggest it as an option when teaching screenprinting in my high school art class. glowing in the dark.
