^ 24 hours should be plenty. I use Jacquard almost exclusively (some speedball), and have done multiple layers on top of each other in the same night/printing session (a couple hours to dry in between colors, at most) no problem. I mainly use 255-305 mesh though, so not very thick coats of ink. As someone else mentioned, I find that the ink tends to build up/stick to the squeegee, so I usually scrape that off (put back in jar) and add some freshly stirred ink to the screen as needed.
It dried in my screens. Harsh clean up. I called Jacquard and spoke to the guy who developed it and he said they removed most of the properties of WB inks to make it what it is. He also said that adding water to it would dry it out quicker, but it’s so damn thick I felt i had to add some water. That may have been the problem, but I used Speedball acrylic and it worked like a charm. The colors are rich and lay down beautifully (especially the 'super opaque white’.) The opaque yellow is more green though, almost florescent. Any tips on bringing it around to a brighter yellow?
