Engraved signs are a great way to make your sign look sophisticated. Most engraved signage is plastic or metal. The two most common are plastics which are white with a color coating. The engraver routes the color which leaves a white image. Brass can also be engraved using the same technique, but then filled with black ink or paint. Some of the most common engraving applications are badges, door plates, plaques, desk plates or anything where small copy is required.
