Determination of dyeing levelness using surface irregularity function

An acceptably dyed fabric must be a match to the target 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 a 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. © 2009 Wiley Periodicals, Inc. Col Res Appl, 34, 285–290, 2009
