|
| When selecting
a front projection surface, consider several key factors: |
|
 |
|
|
|
The quality
of image which the human eye perceives is primarily a function of
gain, contrast, uniformity and resolution.
| 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 Properites |
The ability to perform well under normal to adverse lighting conditions in the audience area. |
| 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. |
Projection
Format |
The height and width of the projected image determines the
screen's size and shape (AV, NTSC, HDTV, WideScreen, CinemaScope,
overhead, slide or motion pictures). |
|
|
Textile
Backed Screen Surfaces
In this group, the reflective surface is
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.

Matt White
A matt white surface diffuses projected light
in all
directions,
so 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. Seamless in virtually all standard sizes.

Care
and Maintenance: Clean surface with a solution of mild dishwashing
liquid diluted with warm water. Sponge the surface, rinse with clear
water and blot dry. Do not use cleaning solvents or abrasives. Download the Care and Maintenance guide |

Glass
Beaded
Spherical
glass beads embedded in surface provide brighter on-axis viewing
than
matt white, within a narrower viewing cone. Glass beaded surfaces
have some loss of clarity and perform best with table-mounted
projectors. Flame and mildew resistant; cannot be cleaned. Seamless
in standard
sizes through 10’ high. Gain Chart |

Care
and Maintenance: Clean surface with a very soft brush or cloth
and carefully dust the surface. Do not use soap, water, solvents or
abrasives. Download the Care and Maintenance guide |

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. Lower gain of 0.8 allows use with even the brightest projectors. Available on most non-tensioned motorized and manual screens, seamless in sizes through 8' high. Viewing cone of 180°. Gain Chart |

AT1200
The
most innovative and versatile acoustically transparent screen
material.
Similar in gain performance to Matt White and does not require
tensioning for flatness. Acoustical properties comparable to the
finest
speaker grille cloth. Washable, flame and mildew resistant. Available in sizes through 72" x 96" or
10' diagonal. Not
recommended for screens smaller than 80" wide when used with LCD or DLP projectors. Gain Chart |

100%
Vinyl Screen Materials
These screen surfaces are tensioned vinyl with no backing. Draper
offers these surfaces on motorized, crank-operated and permanently tensioned screens
with built-in tensioning systems. The surface is stretched perfectly
flat, resulting in better picture quality. Flatness is always desirable,
particularly for video or data-graphics projection.

HiDef
Grey
A grey front projection surface that provides excellent contrast
and black reproduction, with a low gain to
handle today's super-bright projectors. The grey color enhances color
contrast, black levels and allows for
more ambient light in the audience area. Available in
sizes through 9' x 9', or 9' high in greater widths. Gain Chart |

Care
and Maintenance: Clean surface with a solution of mild dishwashing
liquid diluted with warm water. ARMOR ALL® Multi- Purpose Cleaner
may also be used. Remove stubborn stains with a solution of rubbing
alcohol and water. Do not allow any cleaners to be absorbed by the
fabric. Do not use cleaners which contain abrasives or wax. Download the Care and Maintenance guide |
