Abstract (en)
[origin: US2007077119A1] One exemplary optically active material includes a mark that facilitates identification of a preferred application orientation of the material without significantly affecting the optical properties of the material. Another exemplary optically active material is wound into a roll including multiple, individual strips of pre-measured tape. Adjacent strips are separated by a separation line that can be, for example, a perforated separation line or a complete cut that fully separates the adjacent strips.
