Hemlock calls itself "Boston's best T-shirt printers," and it backs up its claim with a no-minimum-purchase policy. The company's in-house design department is happy to help with your project, or you can bring the staff finished art to work with. Hemlock now offers digital garment printing in addition to traditional screenprinting. It recently purchased a new multi-head machine for onsite embroidery. The business has been in its current location since 2006.
