We use a premium heavy weight 13 oz. scrim vinyl banner. It has a very smooth surface for best printing results. This material is typically used for billboards, building wraps, banners, event flags, trade show signage, parades, etc.  Print width maximum 10'.  Anything over 10' will be welded together.  Double Sided option available.  Please ask for quote.  Prices are subject to change at anytime.
