Abstract
Abstract A plastic panel having bas-relief forms on both sides from a reference level, defining thereby at least three general levels, at least two of which are painted and at least one of which is substantially free of paint. A planar plastic sheet is positioned against a mold having spaced high mold sections, spaced intermediate mold sections and valleys defined by said mold sections, and formed onto the mold sections and into the valleys to form the bas-relief relative to the intermediate mold sections. The panel is removed from the mold and painted on both sides on the raised surfaces of the bas-relief islands.
