A retroreflective article having an extensional stiffness, A, bending rigidity, D, and a neutral axis a distance yn from a first major surface of the final article, and adapted for attachment to a flexible substrate having an anticipated bend radius (r), the article comprising:
- an elongate carrier;
- a plurality of discrete segments (of length l) of retroreflective sheeting having a first major viewing surface and a second major opposing surface opposed to the first major viewing surface, the first major viewing surface being disposed on the elongate carrier;
- and
- wherein I is selected based upon calculating
