A method of producing a grating structure comprises the steps of forming a stamp from flexible plastic material, the stamp including a negative of a periodic grating pattern on a first surface; forming an ink by applying a polymer film to the stamp, the ink including a first surface and an opposing second surface, wherein the first surface of the ink contacts the first surface of the stamp such that the ink retains a positive of the periodic grating pattern; placing the ink and the stamp on a substrate such that the second surface of the ink contacts an upper surface of the substrate; and removing the stamp from the ink by applying a tensional force to one edge of the stamp.
