1. A method comprising:
- providing a polymerized optical film structure having a microstructured surface;
forming a scratch having a length on the microstructured surface to form a scratched optical film;
illuminating the scratched optical film to form an illuminated scratch;
measuring a plurality of scratch contrast ratio values along the length of the illuminated scratch with a detector; and
determining a maximum scratch contrast ratio from the plurality of scratch contrast ratio values along the length of the scratch.

9. A method comprising:
-
providing a plurality of polymerized optical film structures having a microstructured surface, wherein each optical film is different;
forming a scratch having a length on each of the microstructured surface to form a scratched optical film, wherein each scratch is formed with a first set of scratch forming parameters;
illuminating each of the scratched optical films to form an illuminated scratch on each scratched optical film;
measuring a plurality of scratch contrast ratio values along the length of each illuminated scratch with a detector; and
determining a maximum scratch contrast ratio from the plurality of scratch contrast ratio values along the length of the scratch for each optical film. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
