Sheeting material is disclosed that contains a retroreflective layer and a layer of luminescent material on the bottom or lower surface of the retroreflective layer. The sheeting material can be formed into signage or decorative articles that are highly visible under a variety of lighting conditions. A portion of the retroreflective layer is visible through the luminescent layer or through one or more openings in the luminescent layer which are in the form of slits, perforations, alphanumeric or other patterns. The luminescent layer can be imaged using analog or digital printing processes. The sheeting material can be made from materials that are suitable for back-lit illumination. Adhesives or other conventional attachment means can be employed to anchor the signs in interior or exterior environments.
