Results Aurora-B is a multi-color rainbow reflective cut heat transfer film, about 165 micron, that bursts into a spectrum of color when light or a camera flash hits it. Supplied at 17.7 inches wide, the flexible film cuts on a vinyl plotter or laser and forgives weeding mistakes, then presses onto most fabrics including polyester and cotton on both light and dark garments. It carries a pressure-sensitive carrier and a heat-activated adhesive. Applied at about 300-315 F with medium pressure. Recommended for fashion apparel, event and party wear, and decorative reflective accents.
