Webcolour loss is a microfade test. Microfade testing is a relatively new method which was introduced in 1999 by Paul Whitmore. Whitmore developed an instrument for accelerated light aging that can be considered non-destructive. Because the test is done on a surface that is only 0.4 mm in diameter, it can be used on even very sensitive objects.

WebMICROFADE TESTING Microfade testing is an accelerated light-fading technique in which the visible reflectance spectrum of a small area of a colourant (c.a. 0.3mm) illuminated by high intensity UV-free visible light is recorded as it changes. Colour change (∆E 00), a perceptual measurement, is calculated from spectral change Web(Neevel and Reissland 2005), and microfade testing. Some of these results have been previously reported (Tse et al. 2006). Hyperspectral imaging combines spectroscopic informa-tion with the spatial information of the sample. In hyper-spectral imaging spectral information is collected in nar- row bands (10 nm) that are contiguous. ...
