Also, here is how to think about printing transparent art on a black t-shirt. Get a black piece of construction paper that is Letter-sized (8.5 x11) and put it in your ink-jet printer. Open up a web page with a big image on it, like a picture of a person in daytime. Print the picture. The results you get is what you’ll have when you set up transparent art on black cloth. It is their process, which is inkjet based I am sure, that causes the problem, because inkjet “inks” are actually thin, translucent dyes.

Silkscreening uses thick, opaque inks that are more like a paint. It is this opacity that doesn’t allow the art to gradate with the cloth to create an effect, or at least you can’t without a lot of hand-holding from the printer. I don’t know if we can submit art to them for review as to how we can make it work. I would assume that “premium” members would get better service, so maybe we can go that route.
