Table 5 illustrates the implementation of the principle of additivity for both total visual differences ([DELTA][E.sub.v,T]) and total instrumental differences ([DELTA][I.sub.T]) at four levels of achromaticity.
Having derived an unequivocally good GAI, the next tangible preliminary investigation was to determine the discrete acceptable and unacceptable tolerance regions for each and a combination of the three geometric attributes (i.e., specular gloss, DOI, and OP) at all levels of achromaticity.
