Which Surface? Textile Backed versus Tensioned Surfaces
Fabric Care and Maintenance Instructions (pdf)
When selecting a front projection surface, several factors need to be considered
- Gain—a relative measure of a screen’s reflectivity.
- Contrast—the ability to accurately reproduce and differentiate light and dark characters and backgrounds, or light and dark areas of an image.
- Ambient light rejection properties—the ability to perform well under normal to adverse audience lighting conditions.
- Resolution—the clarity of the projected image.
- Uniformity—the screen’s performance when viewed from various points off the projection axis (both horizontally and vertically), and when the brightness of the center of the image is compared to the corners.
- Aspect ratio—the screen’s height and width configuration, formatted for the desired projection source (NTSC video, HDTV, WideScreen, CinemaScope, overhead, slide or motion pictures).
Textile Backed Screen Surfaces
These surfaces consist of a reflective surface laminated to a woven textile base. The screen surface hangs suitably flat because of the stability of the material and the weight of the bottom dowel. Good for all types of projection. Commonly used for single lens video projection, as well as for CRT video and data-graphics projection.
AT Grey |
AT Grey offers the acoustical properties of our popular AT1200, while providing the best optical qualities of both Matt White and High Contrast Grey. It is unique in that it offers both a 180° viewing cone and the vivid color contrast associated with high contrast grey materials. Washable, flame and mildew resistant. Available in sizes through 6’ x 8’ or 10’ diagonal. Gain of 0.8. Not recommended for screens smaller than 80” wide when used with LCD or DLP projectors. Peak gain of 0.8. |

AT1200 |
Innovative and versatile acoustically transparent screen material. Similar in gain performance to standard matt white. Acoustical properties comparable to the finest speaker grille cloth. Peak gain of 1.0. |
 |
|
Glass Beaded |
Brighter on-axis viewing than matt white surfaces within a narrower viewing cone. Some loss of clarity. Not for use with ceiling or floor mounted projectors. Flame and mildew resistant, but cannot be cleaned. Now available seamless in all standard sizes through 10' high. |
 |
|
High Contrast Grey |
Grey textile backed surface offers excellent resolution while enhancing the blacks of LCD and DLP projected images, even as whites and lighter colors are maintained. Performs well in ambient light condition. High Contrast Grey’s lower gain of 0.8 allows use with even the brightest projectors; viewing cone of 180°. Available on most non-tensioned motorized and manual screens, seamless in sizes up to 8’ in height. Peak gain of 0.8. |

Matt White |
The standard to which all other screen surfaces are compared. Matt white vinyl reflective surface laminated to tear-resistant woven textile base. A matt white surface diffuses projected light in all directions, so the image can be seen from any angle. Provides accurate color rendition as well as superior clarity. Recommended for use with all high light output projection devices. Requires control of ambient light in the audience area. Washable, flame and mildew resistant. Peak gain 1.0. |

Perforated Matt White |
Allows for speaker placement behind viewing surface. Similar in image quality to Matt White, for use in large screen applications where the nearest viewer is 15’ to 20’ from the screen. |

Care and Maintenance Instructions (pdf)
These screen surfaces are tensioned vinyl with no backing. Draper offers motorized, crank-operated and permanently tensioned screens with built-in tensioning systems. The advantage: the surface is stretched perfectly flat, resulting in better picture quality. Flatness is always desirable and highly recommended for video or data-graphics projection.
Rear Cineflex
|
Neutral grey rear projection diffusing surface with an on-axis gain of 1.3. Cineflex has high resolution and excellent contrast, even in lighted rooms. For use with any type of projection equipment. |
 |
|
Flexible Matt White
|
Pliable matt white material for use in our Cinefold portable folding screen. It can be stretched, folded and restretched repeatedly without damage. Flexible matt white is an excellent matt white material with a gain of 1.0 and a viewing cone of 180°. |
|
|
HiDef Grey
|
A grey front projection surface that provides greater contrast and black reproduction than standard surfaces, with a lower gain to handle today’s super-bright projectors. The grey color enhances color contrast and black levels in the projected image and also allows for more ambient light in the audience area than traditional surfaces. Available on all tab-tensioned and permanently tensioned screens. Peak gain of 0.9. |

M2500
|
Higher gain surface provides good black retention with accurate light colors and whites. M2500 is black-backed, and tolerates a higher ambient light level in the audience area than many front projection screen surfaces. On-axis gain of 1.5. |
 |
|
Black-Backed M1300
|
Our M1300 viewing surface with a black backing for situations where ambient light behind the screen is an issue. Peak gain of 1.0. |

Low-Gain Cineflex
|
New Low Gain Cineflex surface offers a wider viewing cone and added contrast level with a neutral grey tint. This is ideal in applications where ambient light is needed, yet you want to limit your hot spot. This should be considered when you have a bright projector and rigid screens are not an option. Some ideal installs may include churches, training centers, or other large venue need. To order 0.8 Low Gain Cineflex just add LG to the end of any part number for a screen with standard Cineflex viewing surface. |
