The importance of the projection surface
The projection screen is an indispensable part of
the text. While the technical engineering of a good
any presentation or home entertainment
projection screen partly focuses on operation and
installation. Because, regardless of how good the
installation, the projection screen surface is by far
projector itself may be, the image always needs to
the most important element. The choice of screen
be projected onto a surface that allows multiple
surface type determines the screen’s ability to
viewers to see the graphics and comfortably read
handle the projected images.

Three factors play an important role in the choice of a projection screen surface: ambient light levels,
projector performance (output) and the placement of the projector. These variables need to be tuned
to each other in order to create an optimum display.
Types of projection surfaces
Reflective
A reflective projection screen surface reflects the projected light from a ceiling-mounted
projector in a beam in the direction of the viewer. The angle of incidence is the same as the
angle of reflection. Because of the beam effect, the viewing angle reduces but the gain
increases.
Diffusion
A diffusion projection screen surface spreads the light evenly and has a wide viewing angle.
Rather than reflecting the light as a beam, the diffusion projection screen surface disperses
the light evenly and always achieves a gain of close to the norm value of 1.0.
The projector may be ceiling mounted or placed on a table.
Diffusion Transmissive (rear projection)
In the case of a transmissive projection screen surface, the image is projected
from behind the surface and is transmitted by diffusion to the audience side.
The projector may be either mounted from the ceiling or placed on a table.

Screen flatness
affects the resolution in your projection
Non-tensioned screens are only supported vertically,
potentially causing waves or ripples in the projected image.
Tensioned screens are supported both vertically and horizontally,
creating a uniformly flat projected image.
The benefits of using a tensioned projection surface:
Always a guaranteed flat projection surface
The tab-tensioning system will keep the projection surface
under a constant tensioning for a perfectly flat viewing area.
A flat projection surface will get the most out of your projector,
making sure no pixels get lost or deformed. If detail is important
a perfectly flat projection area is vital.
A smoother surface
Non-tensioned fiberglass surfaces have a visible coarse texture
that creates noise in the projected image and greatly reduces
the image quality. The vinyl projection surfaces used in
tab-tensioned projection screens are smoother and preserve
the image quality much better making it suitable for high
resolution projectors.
A longer life cycle
Changes in temperature and humidity
A tensioned projection surface can withstand changes in
temperature and humidity better than a non-tensioned surface.
Resilience
The resilience of the tensioned materials will result in an even
longer life cycle of the product.
With HD resolution especially, only a tensioned screen should be
specified. A tensioned screen will show the flattest and most
pleasing image quality from a projector. Fiberglass surfaces are
non-tensioned materials used for basic manual and electric type
screens and cannot reproduce an HD quality resolution because
the material is only tensioned vertically, potentially elongating
and warping individual pixels in the projected image.
Additional features:
Slim-Tabs
A lower profile, stronger tab design to keep
the screen perfectly tensioned.
Tensioning mechanism
On the slat bar a preset adjustable mechanism is
available to adjust screen tensioning.

HD Progressive
for high resolution
Every projected image will look better
on an HD Progressive surface
Color fidelity – Image uniformity – Pixel preservation
The best surface for HD, 4K and Ultra HD projection
HD Progressive Screen Surfaces
The chemical formula for our HD Progressive line of projection surfaces
is designed to perfectly reflect and preserve the image being projected.
As projection advances the surface becomes more important. We research the science of surface with an in-house team of
dedicated chemists. By studying the physics of light and experimenting with the science of surface we’ve discovered a better way.
Behind each surface is a proprietary, environmentally friendly chemical formula. This means there is a better surface for your image.
Color Fidelity
We hold ourselves to the highest standard when it comes to color fidelity.
All of our surfaces are individually tested and color measured to ensure
each surface will preserve the true color of the projector.
Image Uniformity
It is imperative that the surface reflects light in a manner that maintains the uniformity of
the image being projected. HD Progressive ensures an even distribution of
projected light for a perfect image.

Surface Granularity
The clarity of an image is in the microscopic details.
Our vinyl technology ensures a premium surface,
free of microscopic dips or grooves, so that every pixel is preserved.
When you look closely at a projection screen surface, many surfaces look like varying grains of sandpaper and others have microscopic
variations on the surface. This causes pixel loss and “noise” in the image because the surface isn’t able to perfectly reflect the projected
image. As projection resolution advances, pixel preservation becomes much more important to preserve the clarity of your image.
The chemistry behind a HD Progressive surface is formulated to create a surface free of microscopic variances allowing the screen to
essentially disappear. The result is brilliant light, vibrant color and the best surface for HD, 4K and Ultra HD projection. Choose the HD
