I'm slowly refining my tee printing process and am now using discharge style printing in order to achieve very soft results. You can see how the ink blends with the heather of the fabric versus sitting on top of the garment from the pics I've attached here. It also allows me to increase the size of the graphic without feeling at all heavy while you're wearing it. The second pic shows the graphic on a small tee.
This tee is printed on a super soft American Apparel tri-blend track tee. I bought samples awhile back of literally every tee on the market and determined that this particular one fits and feels best. It's well worth the price of a blank. Check out the the between the shoulders back print as well.
