With the 222 Series from One Stroke Inks, you can screen print untreated 100% nylon without the use of a nylon catalyst. Untreated nylon is nylon without any sort of waterproof or water resistant coating. The 222 Series is unique for more than just its great adhesion, it also tells you when it is cured. The print will be glossy once it is fully cured. If the print comes off the conveyor belt and is not glossy, it is simply not fully cured and you should send it back through your dryer at a higher temperature.
