To cut an optical film having a first surface, a second surface facing opposite side, and a thickness perpendicular to the first surface and the second surface. Forming, cutting, and cutting channels that at least partially pass through the thickness of the film.
A method of printing a light control material in close proximity to the surface of the film, comprising printing, the light control material traversing through the channel by capillary motion. The first aspect of claim 1, further comprising controlling the movement of the light control material such that the light control material travels a predetermined distance through the channel or onto the first surface of the film. Method. The method of claim 1, wherein cutting the optical film comprises a rotary die cut, a platen cut, or a laser cut. Forming a reference mark on the first surface of the film and
The method of claim 1, further comprising printing the optical control material in alignment with the reference mark. The method of claim 1, wherein printing the optical control material comprises flexographic printing or inkjet printing.
