Abstract: Provided are a droplet application device and a droplet application method, which check printing states for at least two directions when printing a test pattern on a substrate to check deviation of the substrate and a nozzle alignment state of an inkjet head for at least two directions. The droplet application device includes: an inkjet system including an ink pack assembly which includes a plurality of inkjet heads and discharges ink from each of the inkjet heads onto a substrate to print a test pattern, a pack transfer part which transfers the ink pack assembly, and a substrate transfer part which transfers the substrate; and a vision inspection unit for determining an alignment state of the inkjet heads by inspecting print direction information of the test pattern printed on the substrate, in which the test pattern includes at least two print direction information.

Abstract: The present disclosure provides a method and apparatus for forming a film, capable of for forming a film on an image in which a plurality of shapes overlap, wherein the method for forming a film includes setting a first shape within a target region; setting a second shape, at least partially overlapping the first shape; setting an edge processing profile applied to an edge portion of the first shape and an edge portion of the second shape; and forming a film on the edge portion of the first shape and the edge portion of the second shape, based on the edge processing profile.
