This paper describes an imaging system based upon a digital camera for assessing the fastness of textile materials to staining and colour‐change. Large sets of samples were assessed by a panel of professional assessors and these results were used to evaluate the inter‐observer and between‐laboratory variations, and the instrumental method against the visual results. In addition, the measured results from a camera imaging system and a spectrophotometer are compared. The results show excellent agreement between the two instrumental methods. The agreement is even better than the inter‐observer and between‐laboratory agreements. It was also found that the present ISO standard formula gave a very poor prediction to the visual results for staining fastness. After a simple correction, the formula fits the data much better. In conclusion, applying a digital camera system plus a revised ISO formula can provide an accurate and rapid method for assessing textile fastness.
