RIBBED LARGE-FORMAT IMPRINTING METHOD

摘要

A method of making a filled large-format imprinted structure includes providing a substrate, locating a curable layer over the substrate, imprinting the curable layer, and curing the curable layer to form a cured layer including a layer surface and one or more imprinted micro-cavities. Each micro-cavity has a micro-cavity depth and a micro-cavity width and one or more ribs extending from the bottom of the micro-cavity toward the top of the micro-cavity. Each rib has a rib width that is less than one half of the micro-cavity width, a rib height that is less than the micro-cavity depth, and each rib separates the micro-cavity into portions, each portion having a portion width less than or equal to 20 microns. A curable material is located in each micro-cavity and cured to form cured material located in each micro-cavity, thereby defining a filled large-format imprinted structure.
