This industry group comprises establishments primarily engaged in printing on apparel, textile products, paper, metal, glass, plastics, and other materials, except grey goods. All printing processes are included here. The materials that are printed upon are not produced by this industry group and they may perform many postprinting activities such as folding, cutting, laminating, or mailing. Support activities are also performed here, such as prepress platemaking, typesetting and postpress services such as book binding.
