1. A retroreflective sheeting, comprising:
full cube microstructured elements having non-triangular reflective faces and an average height ranging from about 0.001 inches to 0.010 inches; and channels that are substantially parallel to a longitudinal peripheral edge of a roll of the sheeting and wherein the channels are selected from a group consisting of primary groove channels, structured channels, and cube cavity channels; and wherein the full cube microstructures comprise a 1-2 dihedral angle error and a 1-3 dihedral angle error that are varied in opposition and differ in sign or magnitude by at least 1 arc minute. |
