摘要
In one embodiment of the invention, retro-reflective sheeting is disclosed. The retro-reflective sheeting comprises a flexible optical material film or substrate having a geometric optical surface opposite a base surface. The geometric optical surface includes a background pattern region of corner cubes arranged at a first orientation with respect to an edge of the retro-reflective sheeting; and an array of circular corner cube regions periodically interrupting the background pattern region of corner cubes. Each of the circular corner cube regions has a second orientation with respect to the edge of the retro-reflective sheeting. The array of the plurality of circular corner cube regions reflects incident light differently than the background pattern region of corner cubes.
