Abstract
A sign having raised or recessed, three-dimensional graphics and a method of making the sign are disclosed. The sign is fabricated from a laminated, multi-layered blank having a substantially continuous face layer formed of a conformable, thermoplastic material; a substantially continuous middle layer formed of a colored film; and a substantially continuous profile layer formed of a profile film. In use, dimensional characters are cut into the blank through the profile and middle layers only. Unwanted material is weeded out from around the cut, dimensional characters, and the resulting blank is vacuum-thermoformed to cause the uncut face layer to conform to the dimensional characters. A background sheet of a color contrasting to the middle sheet is then laminated to the back of the blank to form the completed sign.
