Graphite 70 combines a sophisticated optical coating with an engineered custom acrylic substrate. Thirty percent below unity gain, Graphite 70 delivers enhanced contrast via a neutral density gray component while still delivering superb, off-axis performance. When viewing critical data, Graphite 70 can reduce ghosting tendencies without increasing bloom. Designed to be used with short focal length projection light paths, Graphite 70 functions well in environments with limited ambient light control. With identical gain and color matching for multiple screen applications, this is a great screen for boardrooms, blending applications and simulation.
