What is the optimum resolution for images printing on apparel?
You should make sure that images being printed on apparel are at least 120 DPI. Since the area over which the image will be printed is 11″ x 11″, each image or composite of images should equal 1320 pixels square (120dpi x 11″) to provide the optimum results. In other words, if four separate images are being printed, each side of each 5.5″ x 5.5″ image should be 660 pixels wide.
