I used plastisol for this video. The kit comes with water-based, but then you have to clean out the screens when you are done, because it will eventually dry in the screen. We leave these screens laying around with the ink in them and clean them once in a while if we haven't printed anything with them for a week or so. We offer plastisol on the website, too, and there is no reason not to use it with Merchmakr screen printing kit.
