Silk screened signs are printed on a corrugated plastic also know as coroplast. We print these signs in quantities of 12 or more. Standard sizes are 18x24 and 12x18. In Stock we carry three different color coroplast: white, yellow and ivory. When designing your sign we first think of the most effective way so that your sign can be read from a distance. We want your sign to stand out over its competing signs. The layout of the sign is everything. You will see the difference!
