HC—Dark
grey tint
Exceptional contrast
and color rendition. Excellent light dispersion properties.
The most popular choice for multiscreen VideoWall applications.
Enhances legibility of computer generated data displays with
light or bright text against a dark background: dark colors
and black are reproduced with remarkable accuracy. HC tint performs
equally well with static and moving displays. Not recommended when using a projector having a lens with a throw distance of 1:1 or shorter.
NG—Neutral
Grey
Standard formulation.
Medium grey tint. Normal contrast levels and good color reproduction.
brightness levels are uniform throughout entire viewing cone.
Multipurpose coating suitable for all projection formats and
images.
W—White
Neutral white tint. Low contrast levels
with some loss in color reproduction. Perfect for video and
video conferencing. Requires lower light level in audience area.
Not recommended for computer graphic/data displays when ambient
light is present. Recommended for viewing 3-d applications.
Reflects a laser pointer beam. White is the best tint to reproduce
white backgrounds, so it’s best for viewing spreadsheets. |
