在同一设备和油墨条件下，以不同色度外观的纸张为变量，通过比较灰平衡参数，讨论了纸张色度属性对灰平衡的影响，并分析了纸张色度影响灰平衡的主要原理。实验证明，虽然纸张的色度并不显著，但仍然会对不同阶调的颜色复制产生不同程度的影响，特别是在进行高品质印刷时更应当引起充分重视。

Experiments were carried out on paper of different chromaticity using same equipment and ink. The effect of chromaticity on gray balance was discussed through comparison and the principle was analyzed theoretically. Results showed that the effect of chromaticity of paper is not significant, but if this factor is ignored, it can influence the color reproduction accuracy in different tone area. More attention should be paid to this phenomenon especially in high-quality printing process.
