REFLECTA SCREEN FABRIC TERMINOLOGY
SCREEN KNOW-HOW
The fabric types
A projection screen does not only refract the pro-
jected light, but also distributes it with a single
goal: send as much light as possible into the
direction of the audience.
There are two types of projection screens:
■ Diffuse
■ Reflective
Gain
The reflection properties of a screen are defined
by the gain or luminance factor. This factor
informs you of the luminance of the respective
projection screen in comparison to a surface that
is standard white-coated. The factor expresses
how many times lighter the picture is seen by the
viewer. The larger the gain factor of a screen, the
smaller the viewing angle. Typically, the specified
gain factor indicates the maximum reflection of a
screen along the projection axis. Special coatings
of the projection screens are used to obtain diffe-
rent reflection characteristics. Their effect is to
manipulate the light reflection, i.e. either distri-
buted evenly in all directions or concentrated to a
small viewing angle.
