Yeah, sublimation is intended for white polyester.
For printing on darks, one would use pigment inks and a transfer paper made for dark garments. I don't remember the name of the one that people seem to like best for this ... I'm sure someone will chime in with it. I believe most people have a cutter, too, to trim the excess paper from around the design, else you get the "Box" on the shirt.
