-
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 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).
The
quality of image which the human eye perceives is
primarily a function of gain, contrast, uniformity and
resolution.
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.
Fiberglass
Matt White—The
standard to which all other screen surfaces are
compared. Matt white vinyl reflective
surface laminated to tear-resistant woven fiberglass. 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. Now available seamless in
all standard sizes through 8'
high. Gain 1.0
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.
Panamax—Seamless
matt white material for large roller operated screens—up
to 16' wide.
Panamax has excellent dimensional stability. Washable.
Most motorized screens with Panamax are not UL listed.
Gain 1.0
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.
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.
Gain 2.5
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.
AT1200—The
most innovative and versatile acoustically transparent
screen material. Similar in gain performance to standard
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 6'
x 8' or
10'
diagonal.
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. Allow screen to air dry
overnight in down position. Do not use cleaning
solvents or abrasives. Gain 1.0
 ATGrey
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. Gain .8
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°.
Seamless in sizes up to 8' in height. Gain .8
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.
100%
Vinyl Screen Materials—These screen surfaces are
tensioned vinyl with no backing. Draper offers motorized,
crank-operated and permanently tensioned screens with
built-in tensioning systems. Advantage—The surface is
stretched perfectly flat, resulting in better picture
quality. Flatness is always desirable and highly
recommended for CRT video or data-graphics projection.
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.
Care
and Maintenance: Gently clean material with a
solution of mild dishwashing liquid diluted with warm
water. ARMOR ALL® Multi-Purpose
Cleaner may also be used. It is best to lay the
surface flat during cleaning. Do not use
cleaners that contain abrasives or wax. Gain .8
M1300—The
perfect matt white diffusing surface. Extremely broad
light dispersion and spectral
uniformity. Panoramic viewing angle and true color
rendition. Recommended for use
with any type of projector in rooms where the light
level can be reasonably controlled. Washable.
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 that contain
abrasives or wax. Gain 1.0
M2500—A
high-contrast front viewing surface, with excellent
resolution and high gain. For
data-graphics projectors producing up to 1000 ANSI
lumens. M2500 tolerates a higher ambient light level
than most other front projection screen surfaces.
Available on all permanently tensioned and tab-tensioned
screens. Gain 2.1
Care
and Maintenance: Clean
with a very soft brush or cloth and carefully dust the
surface. Do not use soap, water, solvents or
abrasives.
Cineflex—A
neutral grey vinyl for rear projection. Cineflex has
high resolution and excellent
contrast, even in lighted rooms. For use with any type
of projection equipment.
Care
and Maintenance: Gently clean this rear
projection material with a solution of mild
dishwashing liquid diluted with warm water.
ARMOR ALL® Multi-Purpose Cleaner may also
be used. It is best to lay the surface flat
during cleaning. Do not use cleaners that
contain abrasives or wax. Gain 2.2
