DM7600 is a high-intensity prismatic (microprismatic) retroreflective sheeting, made with a PMMA (acrylic) front film, designed for permanent traffic signage, highway signs and road-crossing signs that need long-term outdoor durability and strong night-time reflectivity under vehicle headlights. This listing is the fluorescent yellow-green colourway, the high-visibility shade commonly used on pedestrian-crossing, school-zone and warning signage specifically because of its strong daytime and low-light conspicuity. It's constructed from sealed air-backed microprisms that use total internal reflection (rather than embedded glass beads, as in older reflective sheeting types) for higher reflective brightness, with a scratch-resistant, printable PMMA surface. Supplied as a bulk roll, 1240mm wide by 45.7m long, sized for sign-makers and traffic-safety fabricators rather than a single small sign.
