Frequently Asked Questions
Where can I buy a Euroscreen® product?
Euroscreen® products are only sold by qualified AV dealers. Contact our sales office to find your closest dealer (see the last page of this catalogue for contact information).
Are Euroscreen® products kept in stock?
Euroscreen® products are manufactured only by orders. The normal lead time is 1-2 weeks.
Are Euroscreen® products CE approved?
Yes.
Are the screen limits set in the factory?
Yes, please note that the projection screen is set at its outer limits when delivered. Incorrect adjustment of the screen limits may damage the product and eliminate the warranty. Make sure to always order correct screen size for each specific installation to avoid tampering with the screen limits afterwards and therefore jeopardise the functionality of the screen.
On which side are the motor and cable attached on projection screens?
By default, the motor and cable are mounted on the left side of Euroscreen® projection screens. Sesame 2.1 is an exception, where motor and cable are mounted on the right side (facing the front of the screen).
What is a Tab Tension screen?
A projection screen type that has connections on all sides of the screen material, which pull it taut in order to achieve a flat screen surface. Please note that the surfaces used in Tab Tension screens are sensitive to heat and are not suitable as black-out, or sun protection. Do not install close to heat sources like radiators, amplifiers or turned on TV-sets.
What is gain?
As it applies to projectors, gain is the measurement of a projection screen’s light reflectance with unity gain being one. A high gain screen will reflect more light along a narrower path than lower gain screen. Screen gains under one use a grey screen to absorb ambient light to help maintain contrast ratios.
How do I maintain and clean a projection screen?
To protect the screen when not in use, store it in fully retracted position. Do not install the screen close to heat sources like radiators, amplifiers or turned on TV-sets. To clean the screen surface, carefully use only neutral cleaning such as water and soap. Stains like paint or ink might be impossible to remove, but contact sales office should you need advice. Projection screens are generally not suitable as black-out or sun protection. Contact sales office for more information about window shades.
Do Euroscreen® products have any warranty?
Euroscreen® products are covered by 2 year warranty from invoice date. The warranty is valid for any damage caused by wrong manufacturing. Please note that any incorrect tampering with the screen limit may discontinue the warranty of the product. The warranty does not cover any damages for transport; please contact the company responsible for the transportation.
Where should I to turn to with any complaint?
Any complaints are directed to the dealer where you made your purchase. We reserve the right to check a returned product before replacing it.
One of the most important decisions in screen selection is to determine the correct size of screen based upon the dimensions of the audience area, and the projection format(s) to be used. In some situations, these two questions yield the same answer; in others they do not and compromises must be made.
Audience Area
In determining the correct screen size in relation to the audience area, the goal is to make the screen large enough so those in the rear of the audience area can read the subject matter easily, but not so large that those in the front of the audience area have difficulty seeing the full width of the projected image.
Width
The general rule to be applied is that the screen should be of a width that is 2/3 the distance between the screen itself and the front row of the audience. Put another way, the closest people should be 1.5 times the width of the screen away. If the audience is large in number the rule is that the screen width should be the total distance divided by five.
Ceiling Height
The bottom of the viewing area should be approximately 100-120 cm above the floor in a room with a level floor and several rows of seats. In rooms with theatre seating or only one or two rows, such as a home theatre, the bottom of the screen should usually be 60-90 cm above the floor. Try to make sure that the lower part of the screen will be visible from all seats. Extra drop may be required to position the viewing area at a comfortable viewing level in a room with a high ceiling.
Height
Screen height is generally determined by the width of the screen and the projection formats to be used.
Projection Format
Once you have determined the correct size of screen for the audience area, that size may be modified based upon the type(s) of projection equipment to be used. If the screen will only be used with one type of projector, it is easy to determine exact screen dimensions based upon the projection format of that projector. Projection formats are expressed in terms of aspect ratio, which is the relationship of the width of the projected image to its height; 4:3, 16:10, 16:9, 2.35:1.
