For rear projection the screen must be translucent.
For front projection, we recommend the use of screens with low
gain specifications (i.e. 1. to ). The use of high gain screens
should be avoided due to their limited viewing angle, which is
undesirable for a large audience.
Preferably, use a screen with black, non-reflecting borders,
which will perfectly frame the projected image.
