Type 11 Ultra Brilliant Wide Observation Sheeting is the newest type of retro reflective film on the market. It combines long sign distance reflectivity with wide observation technology. The resulting film can be seen from farther away than comparable films, and is visible at wider observation angles. (higher angles from the light source) In the case of ORALITE® 9900 Brilliant Grade Premium, it consists of sealed cells of air backed micro-prisms that utilize total internal reflection, a technology that returns more light to the source. Prismatic arrays for type 11 are also deeper, and angled slightly to widen the cone of reflectivity. All of theses characteristics result in the most advanced retro reflective sign sheeting on the market.
Type 11 is made by several manufacturers, however for the purposes of this article, we are using the technical data sheet (spec sheet) from Orafol. Other type11 sheetings will have similar photo-metrics.
