Printing Technology and Materials

Our reflective Coroplast signs are made with high-quality 4mm white Coroplast as the base material. It provides excellent durability and weather resistance. The reflective properties come from a 4 mil reflective adhesive layer applied to the surface. It is this layer that gives your reflective vinyl signs the eye-catching visibility you need.

 

Our reflective Coroplast printing process is based on applying UV-cured inks directly onto the material. You can choose between single-sided printing or double-sided printing, depending on your needs and setup location.

The retroreflective film ensures all critical road information is easily seen and readable from afar.
