A method for manufacturing an optical film (1) is disclosed. The method comprises the step of providing a continuous sheet of transparent plastic material (2). One side of said sheet of transparent plastic material (2) is coated with a layer of curable transparent resin. The coating of curable transparent resin coating is embossed using an embossing roller (5) having a surface, with a predetermined surface structure, so as to provide a desired optical structure in said curable transparent resin. The curable transparent resin is cured, while the curable transparent resin is in contact with said embossing roller (5), so as to harden said desired optical structure. |
