幕料常见问题
  • Q1: I'm considering purchasing an Active 3D projector. What benefits are there in choosing the Airbright 3D2 material?
    • A: In general, the Airbight 3D2 material is beneficial to use with Active 3D projectors to combat the following.

      •Active 3D projectors lose brightness when 3D mode is activated (approximately 50% of lumens is lost)

      •More is lost when the active shutter glasses are put on. The dark tint of them block the projector's lighting. It's like trying to watch a movie with sunglasses on.

      The 2.2 gain on the Airbright 3D2 material helps regain brightness levels in 3D mode, and the high gain avaialble on the Airbright 3D2 allows for some ambient light to be on without washing out the projected image as typically experienced on matte white surfaces.

      The loss of brightness impacts the true home theater experience by producing a dim and bland image. We recommend using the Airbright 3D2 for this reason.

  • Q2: Will I sacrifice picture quality using Elite’s AcousticPro4K (4K resolution Acoustically Transparent) screen material?
    • A: All acoustically transparent materials on the market today are light enough in thickness to allow sound to penetrate it with low-level attenuation (decrease in sound quality) but normally come at the cost of having considerable light loss as well. Elite’s AcousticPro 4K acoustically transparent (AT) material is an exception to this rule. It has an astonishingly fine (.01mm) micro-perforated texture that allows sound to breathe through the fabric with minimal attenuation. At the same time, it allows the video aspects of the material to perform on the same level as a typical matte-white (non-acoustic) material does. The ultra-fine perforations of the Acoustcpro 4K “AT” material allows it to be used with high resolution (4096x2160 pixel ratio) projectors. A special reflective compound coats the surface of Elite’s 4K acoustic material to compensate for light penetration by reflecting the brightness of the projected image. All these features come together to form a product with superior acoustic transparency that has just 1% light loss while presenting a neutral color temperature (6500°-7000° Kelvin). This is equivalent and in some cases, even surpassing in video performance to a standard matte white non-acoustic projection screen.
  • Q3: Will I sacrifice picture quality using Elite’s AcousticPro 1080P2 (Acoustically Transparent) screen material?
    • A: All acoustically transparent materials on the market today are light enough in thickness to allow sound to penetrate it with low-level attenuation (decrease in sound quality). However, the thin fabric properties in the AT material that allows acoustic transparency to occur also allows light penetration resulting in light loss which creates a dimmer image. The (.18mm) perforated texture of the Acoustcpro 1080P2 material is for use with higher 1080P (1920 x1080 pixel resolution) projectors. A special reflective compound coats the surface of Elite’s 1080P acoustic material to compensate for light penetration by reflecting the brightness of the projected image. All these features come together to create a product with an overall audio attenuation of less than 3% while presenting a neutral color temperature (6500°-7000° Kelvin) in an image that is comparable to a standard matte white non-acoustic projection screen.
  • Q4: What is the difference between AcousticPro1080 and 1080P2 Material?
    • A: The AcousticPro1080 material was Elite’s first generation of 1080P (1920x1080 pixel resolution) projection screens with .22mm openings in the weave for acoustic penetration. The AcousticPro 1080P2 material is the next generation with finer (.18mm) openings in its weave for enhanced audio/video performance.
  • Q5: How far should I place my speakers behind Elite’s AcousticProA1080, AcousticProA1080P2 & the AcousticProA4K (Acoustically Transparent) screen materials?
    • A: projection screen mounted flush against the wall over a properly installed in-wall speaker will have a sufficient distance by itself. There will generally be about a 1” total distance between the speaker’s dust cap (depending on make/model) and the screen with a 5mm (.2”) spacing between an in-wall speaker’s grill and the AT screen material itself.
  • Q6: Will I sacrifice picture quality using Elite’s AcousticPro1080P (Acoustically Transparent) screen material ?
    • A: Elite’s Acousticpro1080P material has .22mm openings in its weave that allows sound to penetrate the material with reduced attenuation when used with standard resolution projectors. The material’s weave design is vastly superior over older perforated-PVC acoustically transparent (AT) materials. The porous weave of any screen maker’s acoustically transparent material allows light to penetrate at the expense of creating an image that is dimmer than a regular (solid) white projection material would be. Elite counters this problem by coating the surface of the weave with a reflective compound that enhances brightness and color balance. This feature maximizes your projector’s ability to maintain its contrast levels while presenting a fairly bright image with neutral color temperature. Together, good picture quality and the reality factor created by a shared video and acoustic origin is possible.
  • 问:我应该选择什么样的幕布材质?
    • 答:屏幕材质主要取决于两个方面, 一个是应用的类型,环境,和投影机。 请查看幕布材质以便更好的理解。
  • 问:张力和非张力屏幕材料有什么区别?
    • 答:受张力的材质是提供好的屏幕表面,光的扩散比较均匀, 布面比较平整,不会有波纹。温度可能会对材料有影响, 没受张力的幕布材料, 例如我们的MaxWhite或者 MaxWhite FG材料从某种情况来讲会大大降低了这些缺陷。 由于美学哲理, 一些人喜欢张力材质,但是非张力屏幕材料也得到了较好的评价。
  • 问:幕布材料的黑色背面有什么好处?
    • 答:黑色背面的一个重要特点是可以防止光渗透,以及增强色彩再现。
  • 问:亿立屏幕高增益材质是角反射还是复古反射?
    • 答. 亿立屏幕StarBright™ 4 和StarBright™ 7高增益材质是角反射。
  • 问:我该如何清理亿立投影幕布?
    • 答:所有亿立屏幕投影材质除了StarBright™ 7 和 StarBright™ 4之外,都可以用柔软的布用肥皂水清清的擦拭。试着用GooGone清理污点。StarBright™ 7材质要用非常柔软的布和温和的肥皂水擦拭。不能擦拭影视表面否则将会永久损伤。

      StarBright™ 4 (WhiteBoardScreen™)擦拭时用喷雾瓶和高密度的擦除器。关于很深的污点,我们则推荐使用低浓度的工业酒精和高密度的擦除器擦拭。。

  • 问:在音响前面放屏幕,是否有个最小距离? 我是否可以将屏幕挂在嵌有音响的墙壁上?
    • 答:极少例外,若幕布镶在墙上,则扬声器前面,且不要直接接近他们。幕布和扬声器之间的距离应该至少大约有5mm至数英寸。扬声器的声音是在震动的过程中产生声音。如果驱动器(包括音圈)直接接触你的屏幕,你的画面则受到震动的影响,产生不好的图影效果。
  • 问:屏幕材质上有轻微的水平线?
    • 答:有一些系列的屏幕材质可能在第一眼看上去在表面会有水平线。有被认为是记忆线。记忆线造成的原因是当柔软的幕布材料卷起来或是生产和销售中间的一个时段的储存。这是正常的可校正的现象。 安装后,将幕布放下来放置几天就可以改善。 几天后, 这个水平线会消失, 使用数年内,不会影响投影效果。
  • 问:不同品牌之间的投影屏幕材料会有哪些不同,这些是如何公正的评比的?
    • 答:主要是这三个方面的标准。 色彩品横/温度,亮度和对比度。颜色温度测量仪表是屏幕保持中立平衡的能力,是测量各种颜色的亮度,在测量温度上确保准确色彩平衡或转换记录。亮度是屏幕投影影像的明亮程度。一个测光表使用于测量10nm亮光的光线强度。对比度是测量亮光和黑暗的比率。它用测光表和闪光仪测量亮光和黑暗的水平,然后计算出两者之间的比率。
  • Q16: Can I use the Insta-RP / Insta-RP2 as both a front and rear projection surface?
    • A: While one may project images on the front of the surface of the Insta-RP/Insta-RP2…the quality of the reflected image may not perform equally, and therefore reduce the overall fidelity of the picture .
  • Q17: Will the CineGrey 5D ambient light rejecting screen material cause the “hot spot” effect?
    • A: Elite Screens CineGrey 5D is a color neutral smooth surface with sparkling elements to increase screen gain in an ambient light room environment. These special characteristics incorporates a diffusion layer over a highly reflective surface which scatters ambient light while improving picture performance with a brighter image.

      The projector itself, however also plays a big part in creating a hot spot. Projectors highest brightness levels are focused in the center, and only about 70% to 80% in the corners. In other words, the uniformity itself is not spread entirely even across the screen, thus creating a brighter spot in the center area.

      To combat this, we recommend the following.

      •Reduce the projector’s light output by choosing an economy mode

      •Install the projector further away from the screen, minimum of 1.5 x the image width

      •Go with a lower gain screen

  • Q18: Why choose an “ALR” screen like CineGrey 5D over CineWhite ?
    • A: Although matte white materials such as CineWhite are ideal for environments where room lighting can be controlled, the image is easily washed out by ambient light. Ambient Light Rejecting (ALR) materials such as the CineGrey 5D are suitable for environments where there are high levels of indirect (ambient) light. This material trades off on the wide diffusion uniformity of white materials in favor of a brighter (angular reflective) image. Elite’s CineGrey 5D incorporates a diffusion layer over a highly reflective surface which scatters ambient light while improving picture performance with a brighter image. This includes color neutrality with enhanced black levels and improvement over Active 3D presentations.

      Andrew Robinson, an industry expert, shared his thoughts with Elite Screens about the performance of the CineGrey 5D ALR material, "…of all the features, the one that gets me and really speaks the most is the fact that the CineGrey 5D material from Elite Screens is the most cost effective ambient light solution on the market today. This is why I use it and this is why I recommend that you check it out for yourself. Because, at the end of the day, we all want performance but we also want incredible value and these are two things that the CineGrey 5D delivers in spades.” Click here to see video of Andrew Robinson's endorsement of the CineGrey 5D.

  • Q19: What is the difference between Elite’s MaxWhite and MaxWhite FG screen materials?
    • A: Elite Screens’ MaxWhite and MaxWhite FG are excellent screen materials for front projection presentations. The materials have a multi-layer weave and textured surface coating that offer perfect diffusion uniformity, color reproduction, and black and white contrast. Both have a 1.1 gain that allows for 180° viewing angles (90° left and right) and are black-backed which avoids light penetration. They are also easy to clean, mildew resistant, and GreenGuard® Gold UL 2818 certified.

      The key difference between the MaxWhite and MaxWhite FG is that the MaxWhite FG has a fiber glass backing. This is beneficial as the embedded fiber glass improves rigidity which results in a more stiff material. Thus, the MaxWhite FG provides the flattest possible surface a non-tensioned screen can offer. Additionally, the fiber glass backing eliminates any side curling non-tensioned materials are susceptible to, especially under cold temperatures. Lastly, the MaxWhite FG is also flame retardant and complies with NFPA 701 Standards.

  • Q20: What is the difference between Elite’s MaxWhite FG and SpectraWhite FG? Why is fiberglass backing important?
    • A: Elite’s MaxWhite FG and Spectra White FG are very comparable as they both are self-supporting matte white front projection screen surfaces with fiberglass backing. Having a fiberglass backing is beneficial as the embedded fiber glass improves rigidity which results in a more stiff material. Thus, the fiberglass backing provides the flattest possible surface a non-tensioned screen can offer. Additionally, the fiber glass backing eliminates any side curling non-tensioned materials are susceptible to, especially under cold temperatures.

      Both the MaxWhite FG and SpectraWhite FG will provide an excellent quality image in light controlled environments. The main difference between the materials is that the MaxWhite FG utilizes a more neutral white material for better white levels. Both the Spectra White FG and MaxWhite FG have viewing angles of 180° (90° left and right). The wide diffusion uniformity on both the materials maintain luminance levels throughout the entire surface.

      The MaxWhite FG is also offered on many more of or products, whereas the SpectraWhite FG is solely available on the Starling and Starling Tension.

      The Spectra White FG material is also slightly thicker than the MaxWhite FG.
