摘　　要：目的研究不同纸张表面性能对印刷品不同阶调密度的影响程度。方法选取6种铜版纸,测量其白度、光泽度、PPS粗糙度、表面强度等纸张表面性能,用喷墨打印机在不同纸样上分别模拟印刷不同阶调的梯尺色块,通过密度计测量各印刷色块的密度,并用灰关联分析法分析实验数据。结果白度的灰关联R值较大,其次为PPS粗糙度的R值,表面强度和光泽度对不同颜色和不同阶调有不同的影响程度,且不同纸张表面性能对黄品青黑四色的影响程度不同。结论纸张白度与印品阶调的关联度较大,在实际生产中,为根据需要的印刷效果选取不同的纸张性能提供依据。Objective To study the impact of the surface properties of different papers on different tone densities of prints. Methods Six kinds of coated paper were selected and measured for their properties of whiteness, glossiness, PPS roughness and surface strength. The printing of different tone step scale color blocks were simulated on different paper samples using ink-jet printer. To analyze the experimental data, we measured the densities of the printing color blocks by densitometer using the method of grey correlation analysis. Results The results showed that the brightness had the largest grey relational R, followed by PPS roughness. The surface strength and glossiness had different R values on different colors and different tones. In addition, different properties showed different degree of influence on CMYK. Conclusion Paper whiteness has the largest correlation with printing quality, so that we need to choose different papers according to the need of printing quality during the practical production process.
