White Mark Brings 4K Screen Excellence To the Post Production Community

Studio design consultancy White Mark Ltd is helping its post-production clients make a smooth transition to Ultra High Definition by supplying a range of acoustically transparent projection screens that dont distort 4K images.

White Mark, which has designed over 150 audio post production facilities in Londons Soho alone not to mention numerous music recording, broadcast, film dubbing and video editing rooms around the world is now an official dealer for Screen Excellence, a UK-based company that specialises in high quality projection screens.

If you want to mount speakers behind a screen, which is usually the case in Dolby-certified surround sound and Atmos post facilities, you need an acoustically transparent material that wont impact on sound quality, says White Mark Director, Alan Cundell. However, sourcing the right screen can be an issue because its not always easy to find the quality professional facilities need at the right price.

From an acoustic point of view, projection screens should be woven, not perforated, and the weave needs to be small enough to avoid the projected image taking on a wavy (moir ) effect. For a while White Mark made its own screens using a very high quality, acoustically transparent woven fabric, but when the industry started moving towards 4K the company realised that the weave of its fabric simply wasnt fine enough to cope with the increase in pixels, so it had to find an alternative.

Screen Excellence provided the solution. The company, which was founded in 2008 by Patrice Congard, primarily makes screens for the high-end home cinema market and had perfected a range of innovative and proprietary screen fabrics (Enlightor 4K, Neo-S and Neo-W) that feature a neutral projection surface and are perfectly white so they dont distort colours. They are also free from moir effect, regardless of the projector used, and offer exceptional acoustic transparency. In the case of Enlightor Neo-S, for example, the screens offer acoustic transparency of less than one dB loss throughout the entire audio frequency range.

"When watching a movie, your senses are focused on the screen, Patrice Congard says. It is where the image and the sound merge, making it the most crucial component in the playback chain."

Although no screen is 100% acoustically transparent, Alan Cundell says that Screen Excellence products are far superior to anything else White Mark has tried because they offer very even sound reduction across the entire frequency range.

This means that there is no need to significantly EQ the monitors to compensate for the screen. The small loss in volume is insignificant with professional monitoring systems, Cundell says.

Screen Excellence screens are available in a range of sizes and can be custom-made to suit the space requirements of a particular post facility.

Ideally you want screens to be made from one piece of cloth, without seams, because that can also impact on image quality, Alan Cundell says. Screen Excellence is able to fulfil this requirement because they make their own fabric. We have yet to specify a screen for a post room that was too big for them to cope with.

White Mark is now the only company in the UK supplying Screen Excellence products to the professional post production market. To date, it has installed multiple Screen Excellence screens in a number of Soho-based facilities Wave, 750 MPH, Redlight and at Envys new facility, where they will be used for sound to picture work on film commercials and trailers.
