Zusammenfassung:	A system and process for making non-continuous articles with patterned microstructures. The articles are of high quality and may be used in flat panel display applications. The system and process use a casting roll with a pattern on the surface of the casting roll for patterning a non-continuous microstructure on a surface of the substrate, and a coating device that is adapted to apply a coating to the surface of the substrate in a non-continuous manner so that areas of the substrate that are coated by the coating device correspond to the casting roll pattern. L'invention concerne un système et un procédé de fabrication d'articles non continus dotés de microstructures à motif. Les articles présentent une qualité élevée et peuvent être utilisés dans des applications d'écran plat. Le système et le procédé utilisent un rouleau enducteur pourvu d'un motif sur sa surface de manière à former une microstructure non continue sur une surface du substrat, et un dispositif de revêtement conçu pour appliquer un revêtement sur la surface du substrat de manière non continue, de telle façon que des zones du substrat recouvertes par le dispositif de revêtement correspondent au motif du rouleau enducteur.
