general usage instructions and warnings for projection foils (sold by metre)!
- Creases due to folding in storage
Generally projection foils are packaged folded up and sent off. In general, these creases disappear after opening and stretching the projection foils on all sides. If it is at all technically possible, projection foils can be sent rolled up too – for an additional fee for packaging and transport. This increases the likelihood of the foils being crease-free, or that the creases will disappear during the recovery process. The recovery process depends on room temperature, assembly stress and time. In the case of remaining visible creases, this does not constitute a reduction in projection foil quality.
- Intended use for projection foils
Depending on the type of product used, projection foils are optimised for use in incident or back light projection for customary light incidence angles for video, slide or film projection. A smooth flat surface can only be achieved by stretching the projection foil on all sides with equal tension. The development of ripples and warping does not constitute a reduction in projection foil quality if the projection foil is not tensioned evenly on one or more sides.
- Use with strip or side lighting:
even tension on all sides is mandatory. Visible remaining creases, seams and warping due to tension or assembly do not constitute a reduction in projection foil quality.
- Evaluating colour deviations and variations in brightness
Projection foils are manufactured in large-scale PVC industry plants and are subject to strict quality controls. However, there are variations within this industry too. These are very slight and are not noticeable in normal light conditions. These deviations are only visible in certain application conditions. Please note that colour deviations only become visible when the viewing angle corresponding to half-light density is surpassed; this is dependent on technical factors and does not constitute a reduction in quality.
- Usage for rolling projection screens
Tüchler ® can provide all projection foils as rolling projection screens with a Superflat finish. Please ask us for an offer. Mounting of projection foils on rolling projection screens by third parties is at your own risk. In this respect, Tüchler® remains free from all liability and/or damage compensation claims.
- Dimension stability and tolerances for cut products
Projection foils are made of thermoplastic material. Therefore, the material’s stretching properties, softness and measurements vary according to changes in room temperature. Thus, cut products are subject to a tolerance of +- 5% at 22°C room temperature.
- Use in winter and cold regions
It must be noted that projection foils can cool off significantly during transport. In such cases, open the outer packaging, then wait at least 24 hours at a room temperature of > 21°C before opening the projection foils. At cold temperatures, the projection foil gets stiff, tears easily on moderately sharp edges and may cause irreversible impressions and stress whitening.
- Projection foil shelf life
With correct usage and storage at room temperature, you will be able to use your projection foil for many years. Projection foils contain softening agents which are exuded over time. Therefore after a few years, colour change, yellowing, brittleness, oily patches on the surface can occur, and it may tear more easily. These appearances are not defects covered by warranty; these are customary, material-related effects due to aging.
- Exclusion of DIN and other photography norms
The projection foil has been optimised for use in theatres, opera, events, trade fairs, tours and similar and therefore different types are distinguished by colour, projection behaviour, sturdiness and flammability. The foil was not developed for use in cinemas or similar. Therefore, all evaluations based on norms for projection surfaces, in particular DIN, and claims based thereupon are excluded, unless this was expressly agreed upon in writing.
