Gator Board (high resolution)
Gatorboard is an indoor only product and an industry standard. It comes in 3/16" thick and 1/2" thick. It also is available with Black foam and Black back. It is an extruded polystyrene foam board bonded between two layers of wood-fiber veneer.
Designed primarily for interior use and is favored for its rigidity. The smooth dent-resistant liners are secured to the foam center with a bond that keeps the panel flat and rigid. The surface does not allow moisture to penetrate, so inks stand out vividly.
