摘　　要：通过对四个打印机彩色三原色墨水的光谱透射率测定及色度学分析,得到每一颜色的三刺激值、色度坐标,比较了这4组三原色拼色的色域大小、彩度值、色相的主波长及补色波长。提出了三原色补色波长之间关系的一个经验公式:及,发现这4组三原色的补色波长与此公式有较好的适应性。Samples of ink-jet colored inks were taken from the original package of four well-known brands of printers, Canon, Epson, Hewlett-Packard and Lexmark. In order to calculate the tristimulus values and the chromatic coordinate of each sample, transmittances of the corresponding ink solutions were determined and the chromaticity analysis then made. Also, the gamuts, chroma values, dominant wavelengths and complementary wavelengths were obtained by the use of the chromatic method. An empirical formula was suggested for the relationship between the complementary wavelengths of the three primary colors: compl.M 10/9(compt,Y)+10, and compl,M=9/10( compl, c)-20. It was found that the empirical formula well fits the complementary wavelengths of the three primary colors for ink sets of the samples studied.
