Flatness of the fabric:
• The black lead must be in the range of min. 300 mm - max. 400 mm in
order to maintain the atness.
• Touch the cloth with your ngers as little as possible. The material is very
sensitive and can only be cleaned to a limited extent due to its surface
coating for the realisation of the special radiation characteristics. This is
unavoidable due to the technology.
• Like all thermoplastics, the fabric is naturally subject to material deforma-
tion with decreasing or increasing room temperature. Slow temperature
changes that affect the product as a whole, as they usually occur indoors,
are harmless (e.g. as they occur when the seasons change).

PROBLEM SOLVING AND USEFUL TIPS
• The surface of the black grid fabric is provided with optical „grid teeth“,
which enable a targeted reection of the light beam from the ultra-short
throw projector and form the image for the viewer. As shown in the sche-
matic diagram: The screen particularly absorbs ambient light from above,
the resistance to ambient light from the horizontal sides is weaker, please
pay attention to the direction of the light beam when using the screen.
• The screen is produced by splicing, and the splice line has a certain curva-
ture due to the upper and lower tension which does not affect the projec-
ted image, which is a normal phenomenon.
