T-shirt great quality, print on shirt not so much

I tested out a full-color print of a logo. The white T-shirt was good quality not thin and see thru like other t-shirts we have tried. The logo that we had put on the shirt seemed very muted and the t-shirt seemed to be coming through the print on the shirt and is quite rough. To the point that the green part of our logo has a whiteish-yellowish tone to it. The printing process needs some work on these shirts. If the quality improves I would order but as of right now I would not order again.
