A new fastness formula based on CIEDE2000 color-difference formula is developed by B. Rigg
and his coworkers. It is very simple to calculate fastness grade for color change than ISO 105-A05 fastness
formula based on CIELAB color-difference formula. Sample pair sets which cover a wide range color space
were accumulated from NCS(Natural Color System) color book. For those sample pair sets, visual
measurement experiment and instrument measurement experiment of fastness grade were carried out and
each performance of ISO 105-A02 fastness formula and newly developed fastness formula was compared
through degree of agreement for visual measurement result. Newly developed fastness formula indicated
improved performance for measuring fastness grade but current ISO fastness formula for assessing change
in color, ISO 105-A05, was confirmed that its performance is inadequate to measure fastness grade. Then
fastness formulae were examined more closely according to particular color spaces and the correlation of
hue, lightness and chrom for measuring fastness grade was also considered in this study. |
