The following applies to Harkness Matt White, Perlux and Spectral 240 cinema screen surfaces.
下面的信息应用于哈克尼斯Matt White白塑幕Perlux高增益幕和Spectral 240等电影银幕。考虑银幕架和银幕幕布余所要求的画面尺寸的相互关系十分重要。参见哈克尼斯银幕资料“电影银幕幕布”中的表格。It is important to consider the size of the frame and screen surface in relation to the required image size.See also diagrams on data sheet "Cinema Screen Surfaces".

- Stretch allowance for the surface is 5% on lace-in frame; 4% on wrap-round
- 银幕幕布的伸拉为拉伸式框架的5%；包框式框架的4%
- Image size is measured as chord on curved frame/screen.
- 画面尺寸的测量为弧形框架/银幕的弦长
- 4% is extra width allowance for a 5% curve frame as recommended by Harkness for gain screens (i.e. depth is 5% of width).If curve is deeper, a greater allowance will be needed.
- 4%为弧度为5%的弧形框架的额外宽度允许量，由哈克尼斯推荐的高增益银幕（即深度为宽度的5%）。如果弧度更大则需要更大的允许量。
- Wrap-round allowance on wrap-round frame is 150mm on each edge.Recommended distance between frame edge and lacing rail is 300mm.
- 包框式框架的允许量为每边150毫米。推荐的幕架边缘到为300毫米。

- Width of curved frame is measured across chord.
- 弧形框架的宽度为弦长测量
Masking遮幅
- Fixed or moving masking cloth is normally used with lace-in frame.
- 固定式或移动式遮幅布同场与绳？？？？？框架使用
- Wrap-round frame can be used without any masking cloth.
- 包框式框架可不使用任何遮幅布。
