Abstract
A tile product having a substantially non-porous vinyl composition base and a multilevel embossing and gloss which has a mechanically embossed mortar-line surround and which is free of gloss defects formed by pockets of air trapped between the wear layer and embossing mold during embossing is produced by applying a vacuum to the press during embossing. Preferably, the tile is laminated in a hot press heated by RF energy and cooled in a cold press to reduce the temperature of the wear layer to below its glass transition temperature.
