Methods for assessing fastness of staining and colour change in textile industry have been widely for many years. However, they are tedious and based upon the judgements of experienced assessors. Although there are ISO methods based upon colour measuring instruments, they are still impractical due to the small size and poor uniformity of the specimens considered. In this paper, a new imaging system together with new fastness formulae have been developed and gave much more accurate results than the visual assessments based upon a group of professional assessors and the present ISO instrumental methods.
