A method of manufacturing retroreflective signs includes: coextruding a rigid substrate layer and an adhesive layer, the rigid substrate layer being suitable for use as a sign board; providing a cube corner sheeting having a structured surface including a plurality of cube corner elements, the cube corner elements having a specularly reflective material thereon; and applying the retroreflective sheeting to the adhesive layer. The method is useable with metalized cube corner sheeting in which the structured surface is formed in a back surface of the sheeting, wherein the cube corner element faces form pyramidal projections in such back surface. The method is also useable with metalized cube corner sheeting in which the structured surface is formed in a front surface of the sheeting, wherein the cube corner element faces form a cavity in such front surface.
