I was wondering what inks work best for showing up on dark color fabrics. I got a bunch of Versatex paints and only the Super Opaque White shows up on dark colored shirts. my red, yellow, blue all come out barely visible on the fabric. its like it soaks in or something. i was wondering if maybe i was doing something wrong with the inks themselves. maybe pressing to hard so that the ink goes into the fabric instead of laying on top of it. so any tips on using Versatex inks or names of good (professional grade) inks would be appreciated.
