ABSTRACT:
A method for producing an embossed information plate, e.g., a license plate, wherein desired indicia are embossed in the front surface in relief form and retroreflective sheeting is adhered to the background portions of the front surface. A reflective sheeting having a low-tack, heat-activated adhesive on its backside is tacked to a plate blank. When the plate blank is embossed with desired indicia, the sheeting is simultaneously cut out according to the indicia. After the cut-out portions of the sheeting are removed, the embossed plate and trimmed sheeting which is tacked thereto are passed between a series of pairs of co-acting, resilient lamination rollers wherein the roller of each pair which contacts the sheeting is heated. The rollers conform to the contour of the indicia and heat the sheeting and adhesive, thereby causing the adhesive to effectively wet the surface of the plate and activating it as the sheeting is simultaneously laminated to the plate.
