Abstract

The present invention provides a tiled cube corner retroreflective sheeting that exhibits improved retroreflective performance in at least one plane substantially parallel with an edge of the sheeting, and preferably in two or more planes.
A tiled retroreflective sheeting includes a structured surface having a plurality of cube corner element arrays oriented at predetermined angles relative to the edge of the sheeting.
The angles are selected to align at least one broad plane of entrance angularity approximately parallel with the edge of the sheeting and preferably to align another broad plane of entrance angularity approximately perpendicular to the edge of the sheeting.
