If you’re expecting to have rather high-volume orders on a consistent basis, then screen printing may be the best bang for your buck method of printing. Depending on a number of factors (such as how big your design is, the ink quality, and so forth), you can expect to print anywhere between 200-600 t-shirts with a single gallon of ink, which makes this method very affordable and profitable for large orders. If you are only expecting to print a few t-shirts here and there, screen printing is not the way to go.
