A screen of carefully chosen characteristics: size, material, and mount is necessary for professional presentation. It helps in presentation and its presence communicates professional approach.
Screening on a white wall does not bring a comparable effect. This is why we recommend use of the 2×3 screens.
The main features to be considered when the screen is selected
Portable or fixed?
Size – the size shall be determined by the distance between the screen and the public:
- Minimum distance should amount to 1.5 × screen width
- Maximum distance should not exceed 6 × the width
Format – each kind of projection requires a specific format: ratio of width/height:
- 4:3 Projectors
- Panoramic projection 16:9 (home cinema)
- OHP text display – 1:1
- Slide projectors 3:2
Screen area:
- Reflection – defined by the so called gain factor. It affects the perceived brightness of the image and depends on viewing angle The higher gain factor the more bright the image is.
- Office and school products usually use one of the two kinds of surface:
- D surface (white matt) – gain factor 1.0–1.2 (DIN 19045).
- S surface (glossy white) – gain factor 1.8–2.4 (DIN 19045), the image is twice as intense as D image.
Matt White surface
The Matt White is the most universal type of screen surface. The material is very light what translates to the product’s weight. It can be used in dimmed premises with windows screened or with bright light behind the screen. The surface should be cleaned with soft tissue – water and mild detergent.
Screen material:
- Gain factor: 1.0 – 1.2 (DIN 19045)
- Thickness: 0.35 mm
- Front: white matt
- Back: black
- Viewing angle: <160°
