Abstract
A surface covering, particularly a floor covering, has a visible surface with inverted images of spherulites. The inverted spherulities are formed on the visible surface by solidifying the visible surface while in contact with a release carrier having spherulities on its exposed surface. The level of gloss is determined by the number of inverted spherulite images and whether the images are impinging or non-impinging.
