Title: METHOD OF MANUFACTURING PATTERN ON A SUBSTRATE WEB AND APPARATUS THEREFOR
Abstract:
A method of manufacturing a pattern on a substrate web is disclosed, comprising: providing a production tool having a surface relief structure of elevations and depressions, the elevations corresponding to the desired pattern to be applied to the substrate web. A curable material is applied to the elevations of the surface relief structure on the production tool. The applied curable material on the surface relief structure is brought into contact with a substrate web at a first location. The substrate web and surface relief structure are transported together in contact from the first location to a second location, the first and second locations being spaced from one another along the transport direction of the substrate web. The substrate web is separated from the surface relief structure at the second location whereupon the curable material forming the pattern is affixed to and carried by the substrate web. The curable material on the substrate web is cured by exposure to at least one curing energy source, either while the substrate web and surface relief structure are in contact between the first and second locations and/or after the substrate web has been separated from the surface relief structure at the second location.
