Sublimation - can only be put on poly blends with a minimum of 50% poly. The higher the poly count and lighter the shirt the better the design will show.
Best on a white or marble shirt as the ink dyes the polyester fibers. But can also be done on a light grey and some other light colored shirts.
The sublimated color chart is shown on a Bella Canvas marble/white fleck tank that has 65% polyester. This color chart gives you an idea of what different colors will look like once the design is sublimated.
