4K SCREEN EXCELLENCE 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 don’t distort 4k images. White Mark, which has designed over 150 audio post production facilities in London’s 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 won’t impact on sound quality,” says White Mark Director, Alan Cundell. “However, sourcing the right screen can be an issue because it’s 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 (moiré) 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 wasn’t 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 don’t distort colours. They are also free from moiré 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.” 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.
