摘要：In this paper the effect of whiteness attribute of white substrates on blackness property of black coated fabrics is investigated. To this aim, four cotton fabrics with different whiteness and tint attributes are used as white substrates. To prepare a set of black samples, various concentrations of four color pigments, i.e., red, green, blue and yellow, were mixed with the black one and applied on white fabrics via the routine textile printing method. Then, the colorimetric attributes of black coated fabrics prepared by applying of the same recipes on different white substrates were investigated. The results indicate to the effect of substrate’s whiteness index and tint factor on colorimetric characteristics of achieved blacks where by decreasing of the whiteness attribute of white substrates the black coated fabrics became darker and more saturated. Besides, depends on the colorimetric attributes of employed white substrate, the tint attributes of black coated fabrics differ, dramatically. As a summary, the general imagination of dominance effect of blackness rather than the whiteness attribute of employed white substrate is not approved.
