Abstract
A method for making a light guide includes transferring ink onto a master tool having a three-dimensional feature pattern formed thereon and then transferring ink from the master tool to a transparent light guide. The method also includes curing the ink on the light guide. Alternatively, the ink may be printed onto a substrate (e.g., a film) and then laminated to the light guide.
