Abstract
Abstract A process of making raised line imprinted display mounts utilizing a foam polymer sheet having a thin polymer laminate covering includes the step of selecting a foam polymer sheet having a thin polymer laminate covering. The laminate covering surface is foil stamped with a die under predetermined pressure at predetermined temperatures and for elected dwell time to produce a raised line imprinted lettering or designs on the surface resembling an embossed surface stamping.
