Aluminum and bronze PhotoRelief plaques. All bronze plaques are highlighted using oxidizing technologies to bring out the contrast in the images selected. If Aluminum is selected as the base material, a two-part acrylic polyurethane paint wash is used to enhance the contrast between recessed and highlighted areas. In addition, a full-color Giclee option is also available which can reproduce 1200 dpi full color highlighting on the PhotoRelief plaque. 10" W x 10" H
