[57] ABSTRACT
A method of producing a sign having raised colored characters arranged in a predetermined design. A male die is provided presenting the predetermined design; a substrate sheet is positioned over the male die; the substrate sheet and die are passed between pinching rolls to emboss the substrate sheet with raised areas corresponding to the predetermined design; a color transfer sheet is positioned over the embossed substrate sheet; the embossed substrate sheet with the color transfer sheet positioned thereover is passed between pinching rolls to transfer color pigmentation from the color transfer sheet to the raised areas on the embossed sheet and "tip" the raised areas; and the embossed color tipped sheet is secured to a sheet of relatively rigid base material. The signs produced in accordance with the invention methodology are especially suitable for satisfying handicapped signage requirements and, specifically, are especially suitable for producing signs in compliance with the Americans with Disabilities Act.
