Photographic imagesWe perform evaluation of the permanence of images in accordance with test programs developed together with our customers.
Both conventional photographic material and images produced with e.g. inkjet printers can be evaluated.
Light fastness is evaluated in test programs where the images are subjected to light similar to daylight but with much higher intensity so that the results are obtained in short time. What is often called UV-permanence is tested in this manner. This is a misleading term since the UV-part of indoor light is very small.
The image to the right was illuminated. The colours have changed, especially the yellow colour.
