Textile Backed Screen Surfaces
Matt White—
The standard to which all other screen sur faces
are compared . A matt white surface diffuses projected light in all
directions, so the image can be seen from any angle . Matt white offers
accurate color rendition, as well as superior clarity because it is a smooth
surface, not embossed . Recommended for use with overhead projectors
and high light output projection devices . Requires adequate provision
for the control of ambient light in the audience area . Gain of 1 .0 with a
panoramic 180° viewing cone . Seamless in virtually all standard sizes .

High Contrast Grey—
Grey textile-backed surface offers
excellent resolution while enhancing the blacks of LCD/DLP
projected images . 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' high .

Glass Beaded—
Spherical glass beads embedded in surface provide
brighter on-axis viewing than matt white, within a narrower viewing
cone . All 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 up to 10' in height .

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 . Available
in sizes through 72" x 96" or 10' diagonal . Gain of 0 .8 . Not recommended
for screens smaller than 80" wide when used with LCD or DLP projectors .

M2500—
A high contrast surface with excellent resolution for
projectors producing up to 1000 ANSI lumens . Provides good black
retention with accurate light colors and whites . M2500 tolerates a higher
ambient light level in the audience area than many front projection
screen surfaces . On axis gain of 1 .5; viewing cone of up to 180° .

HiDef Grey—
Grey front projection surface that provides
excellent contrast and black reproduction . HiDef Grey is
designed with a low gain of 0 .9 to meet the demands of 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 .

Draper offers two different types of projection screen surfaces—
textile backed and unsupported vinyl .
Supported—The reflecting surface of the front projection screen
is laminated to a woven textile base which provides the necessary
dimensional stability (stiffness) so the screen fabric will operate
satisfactorily on a roller . Materials of this type are used on spring-
roller operated and motorized projection screens . The screen hangs
suitably flat by virtue of the dimensional stability of the material and the
weight of the dowel in the bottom of the screen .
Unsupported Vinyl—This type of screen surface consists of the vinyl
reflective surface only, with no textile backing . Transmissive rear
projection surfaces are also available . These screen surfaces, whether
for front or rear projection, need to be tensioned to achieve sufficient
flatness to perform properly . Draper offers three types of screens with
unsupported vinyl surfaces, all of which may be specified with front
or rear projection surfaces—
textile backed and unsupported vinyl .

• Portable—folding screens .
Advantage of Tensioned Screens—The surface is stretched perfectly
flat, resulting in better picture quality . Surface flatness is desirable
with any type of projection and highly recommended for data-
graphics projection . Because of their requirement for tensioning,
screens made of unsupported vinyl cost more than conventional
textile-backed screens . Usage of unsupported vinyl screens has
grown in recent years . Buyers are increasingly willing to pay for the
superior image quality which screens of this type provide .
Surface Cleaning—Developing a cleaning schedule is
recommended . See www.draperinc.com/go/ScreenSurfaces.htm for
care and maintenance .

What is Gain?—
Gain is a measure of 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 . With today’s brighter, high output
projectors, gain is not as important as it once was because the screen no longer has to make up for a lack of projector brightness . Other
factors—such as color contrast and accuracy, uniformity, reproduction of black and the ability to perform with more ambient light in
the audience area—are equally important .
