* Which screen type?
There are two major categories of screens used for projection
equipment. Those used for front projected images and those for rear
projection applications.
Screens are rated by how much light they reflect (or transmit in the
case of rear projection systems) given a determined amount of light
projected toward them. The ‘GAIN’ of a screen is the term used. Front
and rear screens are both rated in terms of gain. The gain of screens
range from a white matte screen with a gain of 1 (x1) to a brushed
aluminized screen with a gain of 10 (x10) or more. The choice
between higher and lower gain screens is largely a matter of personal
preference and another consideration called the Viewing angle.
In considering the type of screen to choose, determine where the
viewers will be located and go for the highest gain screen possible. A
high gain screen will provide a brighter picture but reduce the viewing
angle.
For more information about screens, contact your local screen
supplier.
* What image size? How big should the image be?
The BARCOGRAPHICS 8200 is designed for projecting an image
size (video) from 1.00m (3.3ft) to 15.00m (49.2ft) with a aspect ratio
of 4 to 3.
