Corrugated plastic is the material of choice for your short-term signage needs. We use only opaque coroplast, so your double-sided prints stay crisp and clean without graphics showing through. Our digitally printed full color or spot color coroplast signs are tough, waterproof, and dent resistant. The opaque white core delivers vibrant, true-to-color prints every time. Ideal for outdoor yard signs and indoor point of purchase applications, coroplast is lightweight and easy to install. SignMaster.com can also custom die cut coroplast to any shape.
