Diamond Grade™ DG3 can be distinguished from other Diamond Grade products by the presence of the “primary groove line.” Diamond Grade DG3 is designed to be an effective wide angle reflective sheeting regardless of the orientation on the substrate or ultimate orientation after installation. However, because the efficiency of light return from cube corner reflectors is not equal at all application angles, especially at increasing entrance angles, it is possible to get the widest entrance angle light return when the sheeting is orientated in a particular manner.
