Abstract
Methods are generally disclosed for forming and using a casting paper. In one embodiment, the casting paper can be made by coating a first surface of a base sheet with a release coating such that the release coating covers the entire first surface of the base sheet. A printed release coating is then applied on a portion of the first release coating, and is dried or cured as needed to form the casting paper having a textured surface defined by elevated areas corresponding to the printed release coating and valley areas corresponding to exposed areas of the printed release coating. In another embodiment, the casting paper can be made by first printing a base sheet with a patterned, structured coating, then coating over the patterned, structured coating with a release coating such that the release coating covers at least the unprinted areas of the base sheet. The casting paper can be used to form a texturized surface in a substrate.
