Signs and banners can be used inside and outside. Signs can be printed on a corrugated type plastic for outdoor signs, on 1/8″ or 1/4″ PVC for a sturdier indoor or outdoor sign, on a heavy photo type paper for indoor signage or an inexpensive paper stock for a simple poster. Banners are printed on a heavy vinyl and are designed to be outside. They are waterproof and come with grommets so they can easily be installed. They can be printed one or two sided.
