An acceptably dyed fabric must be a match to the forget and is visually even in appearance, that is, level. Although color difference measurement can objectively, determine whether a match has been achieved, levelness is still determined subjectively. leading to inevitable disagreements between dyer and customer. The levelness of a series of dyed fabrics has been objectively evaluated using et surface irregularity function derived from analysis of digital images of the fabrics. The measurements derived correlate more closely to visual assessment than do K/S Measurements. (C) 2009 Wiley Periodicals. Inc.
