Star flex prints are the option chosen by most of our customers for their outdoor prints. 'Star' is actually a brand of premium flex media. At 340 gsm, it is much thicker than regular flex. This means that the material is stronger and will last much longer in an outdoor environment. More importantly, Star flex has a superior coating on its front surface. This enables us to produce high resolution images on it. And the colors of the same look extremely vibrant.
