Northwood is a custom clothing printer serving Pittsburgh's South Hills. Visit our clean & friendly shop whenever you need personalized apparel for your business or special event. We specialize in digital direct to garment printing. Direct to garment printing, or DTG, is a clothing print process where small micro nozzles apply thin layers of ink to apparel. It allows for smooth color transitions, color gradients, and a high level of detail in printed art. Sublimation printing takes advantage of the chemical properties of dyes, whereby heat is used to fuse colors to fabrics & hard surfaces.
