Decoding Viewing Surface Names
Each surface has a name that includes the characteristics it has. The following shows an example with definitions and examples of each area listed below.
X: Extra-wide. Half gain is greater than 60°
M: Moderate. Half gain is 30-60°
C: Controlled. Half gain is less than 30°
T: Typical. Surfaces with "typical" contrast are white in color and are generally recommended for use where ambient light is controlled.
H: High. Surfaces with "high" contrast usually have a grey surface or substrate. Their black retention is enhanced and they perform well under reasonable levels of ambient light.
S: Superior. This designation is reserved for surfaces with remarkable contrast and resistance to ambient light. Our "superior" surfaces will meet or exceed the contrast offered by any competitive viewing surface.
The numeric portion of the name is its typical peak gain x 1000. Gain levels of surfaces cover the full range from 0.6 to 3.2, and minor variations may occur between the samples. Lower gain surfaces offer excellent uniformity across wide viewing cones, for excellent edge blending and consistent reproduction with short throw projectors. Higher gain surfaces offer a more brilliant display in a variety of settings.
* Gain is a measure of reflected or transmitted brightness as compared to a block of magnesium carbonate, which serves as the industry's standard for gain of 1.0. A more familiar "real-world" comparison is with a matt white projection screen. Most matt white screens have a fairly uniform light distribution pattern with gain of approximately 1.0. Screens that appear brighter on axis are concentrating reflected light in a narrower area: the gain may be 2.5 on axis but 0.5 at 60° to the side.
Some viewing surface codes include an E or V suffix after the gain number.
E: Indicates a self-supporting viewing surface that is part of the OptiView family and/or suitable for Draper Series E non-tensioned screen models.
V: Indicates the surface is part of our OptiFlex family of tensioned surfaces and/or suitable for Draper Series V tensioned screen models.
Viewing Surface Family
The CineFlex family features premium rear projection viewing surfaces with the flexibility of choice of gain and color to meet a wide range of rear projection needs. CineFlex surfaces are available on a wide range of fixed frame screens, portable, and tab-tensioned projection screen models.
