White Coroplast - Coroplast is a fluted/corrugated plastic widely used in screen printing to produce more graphics-oriented prints meant for temporary use. You will probably have seen it used for everything from yard signs to displays at pop-up trade shows. We now offer these, printed with UV outdoor inks for any artist or graphics professional that needs a quick and easy printed display for their next art show or event. These can be ordered in custom sizes up to 4x8'. Note shipping may need to be calculated after the order is placed for sizes over 3x4'.
