A: Elite Screens’ MaxWhite® and MaxWhite® FG are excellent screen materials for front projection presentations. The materials have a multi-layer weave and textured surface coating that offer perfect diffusion uniformity, color reproduction, and black and white contrast. Both have a 1.1 gain that allows for 180° viewing angles (90° left and right) and are black-backed which avoids light penetration. They are also easy to clean, mildew resistant, and GreenGuard® Gold UL 2818 certified. MaxWhite® B on the other hand, while maintaining the wide 180 degree viewing angle, has a unity 1.0 Gain that reflects 100% projector light as opposed to 1.1 Gain (110%). It is also formulated to be utilized in our most commonly used front projection screens. This allows more flexibility in our offerings of cost-effective products for mass production.
The key difference between the MaxWhite®/MaxWhite® B and MaxWhite® FG is that the MaxWhite® FG has a fiber glass backing. This is beneficial as the embedded fiber glass improves rigidity which results in a more stiff material. Thus, the MaxWhite® FG provides the flattest possible surface a non-tensioned screen can offer. Additionally, the fiber glass backing eliminates any side curling non-tensioned materials are susceptible to, especially under cold temperatures. Lastly, the MaxWhite® FG is also flame retardant and complies with NFPA 701 Standards.
A: Elite’s MaxWhite FG® and Spectra White FG are very comparable as they both are self-supporting matte white front projection screen surfaces with fiberglass backing. Having a fiberglass backing is beneficial as the embedded fiber glass improves rigidity which results in a more stiff material. Thus, the fiberglass backing provides the flattest possible surface a non-tensioned screen can offer. Additionally, the fiber glass backing eliminates any side curling non-tensioned materials are susceptible to, especially under cold temperatures.
Both the MaxWhite® FG and SpectraWhite FG will provide an excellent quality image in light controlled environments. The main difference between the materials is that the MaxWhite FG utilizes a more neutral white material for better white levels. Both the Spectra White FG and MaxWhite® FG have viewing angles of 180° (90° left and right). The wide diffusion uniformity on both the materials maintain luminance levels throughout the entire surface.
A: Tension material provides a flatter screen surface and for better uniformity and even light distribution without waving or curving on the projection surface. These problems could be caused by temperature variations in multiple layer materials. Newer non-tensioned materials such as our MaxWhite® or MaxWhite® FG have greatly reduced occurrences of this flaw to the point of arguably matching its flatness in some cases. Some prefer non-tensioned due to aesthetics but tension still generally has superior flatness.
