    Abstract: There is provided an article comprising at least a first surface having: (a) a first binder layer; (b) a plurality of transparent microspheres at least partially embedded in the first binder layer; wherein the transparent microspheres have refractive indices that are less than a refractive index of the first binder layer, wherein the plurality of transparent microspheres have an average diameter of at least 5 μm. There is also provided a transfer article comprising: (a) a transfer carrier, the transfer carrier comprising: (i) a support layer; and (ii) a thermoplastic release layer bonded to the support layer; (b) a layer of a plurality of transparent microspheres, formed on a side of the thermoplastic transparent microsphere release layer opposite the support layer, wherein the plurality of transparent microspheres have refractive indices of below about 1.490.

    Abstract: A method of fabricating a nozzle that includes casting and curing a first material using a patterned nip roller to form a first microstructured pattern of discrete microstructures, deforming at least one of the discrete microstructures; replicating the first microstructured pattern, including the at least one deformed discrete microstructure, in a second material different than the first material to make a replicated structure comprising a plurality of blind holes formed in the second material, removing second material of the replicated structure to expose tops of microstructures in the first microstructured pattern, and removing the first material from the replicated structure, resulting in a nozzle having a plurality of through-holes in the second material and corresponding to the first microstructured pattern.
