Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.

A coating apparatus includes a discharge unit, moving unit, and a controller. The discharge unit includes a nozzle array in which a plurality of nozzles is arranged, and discharges a coating material from each of the plurality of nozzles. The moving unit moves a position of the discharge unit with respect to a to-be-coated surface along a plurality of paths substantially orthogonal to the nozzle array. The controller determines, based on coating information, a width of a recoated portion on which the coating material is discharged in an overlapping manner between two adjacent paths among the plurality of paths, and determines a discharge amount from each of the plurality of nozzles so that a discharge amount from each of nozzles at an end portion of the nozzle array corresponding to the recoated portion is less than a discharge amount from each of other nozzles of the nozzle array.
