New technology has led to 3M Diamond Grade DG3 reflective sheeting, the optimal signing material for today’s changing driving environment. 3M DG3 is a thin reflective sheeting adhered to the surface of traffic signs. Each square inch contains thousands of identical microscopic cube corners. DG3’s unique design means that the entire cube surface is reflective. Through the principle of retroflection, a light beam hitting the material is reflected directly back to its source. Since drivers sit in nearly the same plane as their vehicle headlights, the reflected light appears brightest to them.
