DigiGrade textile industry colour fastness grading

Colour Fastness grading for both change of shade and staining of adjacent fabric has traditionally been undertaken by trained and experienced graders using a standard illumination cabinet and set of grey-scales, even with experienced graders this is the most subjective area of textile testing. The DigiEye Colour Fastness Grading option DigiGrade now provides objective and repeatable results. It is most commonly used to evaluate wash fastness results, as well as evaluating Crocking (dry and wet rubbing), change of shade and determining the endpoint and final grade of light fastness.
