Abstract: Various methods and fluid delivery systems are described for printing digitally imaged signs. One method of applying pigmented material to a print medium involves using a fluid delivery system to coat at least a portion of an exterior surface of a cable with a pigmented material and then placing the coated portion of the cable in close proximity to the print medium. An air stream is then directed at the portion of the cable coated with the pigmented material such that a the pigmented material is removed from the exterior surface of the cable and is deposited onto the print medium.

Abstract: A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has alternatively hydrophilic and hydrophobic areas, causing the ink to form droplets on the wire for printing them as discrete pixels onto the substrate.

Abstract: Films having a structured surface with an engineered feature, such as prism grooves, to be used in displays having a backlight. The films can be arranged in a stack having one or more of the following: birefringent brightness enhancement films, non-birefringent brightness enhancement films, polarizers, diffusers, birefringent turning films, and non-birefringent turning films. Those films can be arranged in any order from the backlight to a viewer.

Abstract: Method of Making a Polymeric Film Having Structured Surfaces Via Replication A method of making a polymeric film via a replication process is disclosed. The process provides a tool that has a negative version of a desired structured surface; contacting the negative surface of the tool to a polymeric material to form the desired surface in the polymeric material; removing the polymeric material having the desired structured surface from the tool; and uniaxially stretching the polymeric material.

Abstract: Polymerizable compositions particularly useful for brightness enhancing films.
