Projection Screen Materials

FLATNESS:

Flatness is the core value of the projection screen fabric. We import 5meter width stretchless calendering machine from Italy to imrpove the flatness of the pvc film. The film produced by this machine is from the real width without extending. So the material has top grade consistant thickness, low shrinkage and dimensional stablity. We also have advanced film to film, film to base fabric lamination machines opearted by skilled engineers to ensure the full product line has outstanding flatness.

GAIN:

Gain is a measurement describing the light reflectivity of a fabric, when the measurement is taken for light targeted and reflected perpendicular to the screen. A gain greater than 1.0 means the projection screen fabric increases the brightness of the projected image, while a gain less than 1.0 means the image produced is not as bright. This aspect is affected by the material colour, suface treatment and embossing pattern. We have different types of embossing rollers with delicate patterns to create accurate and uniformed glossy rate for different applicaitons of the projection screen fabric.

VIEWING ANGLE:

Viewing angle is a measurement describing the maximum angle from the center of the screen at which you can still see a quality image. Some projection screen fabric reflect most of the light perpendicularly to the screen, sending much less to the sides. This makes the screen appear much darker and more distorted if the viewers are not in the optimal viewing angle of the screen. Unfortunately, high-gain fabrics tend to have a lower viewing angle.

FABRIC COLOUR:

The color of the projection screen fabric greatly influences the contrast of your final projected image. White screens are the industry standard due to brightness, while gray screens are better at handling darker tones.
