| 中文摘要: |
| 根据印刷机辊筒间油墨压力的非均匀分布，基于油墨渗透深度及印刷参数，建立了在非线性（抛物线分布）印压作用下的油墨渗透毛细管方程。用超景深三维显微系统VHX-600测量了油墨的渗透深度，利用印压、印刷速度及油墨渗透深度测量结果计算了纸张的毛细管半径。该方法所采用的印压拟合非常接近印刷辊筒间油墨压力分布实际，使纸张毛管半径的测量具有更高的精度，对研究在辊体作用下的油墨渗透及纸张毛管对印刷质量的影响，具有实际意义，为纸张毛管半径的测量提供了新方法。 |
| 英文摘要: |
| Based on the parabolic distribution function of ink pressure between two contact printing rollers, using permeating depth formula of printing ink in porous papers, which vary with the printing pressure and printing velocity, the formula of capillary radius was established. By measuring printing pressure, printing velocity and the permeating depth of printing ink in porous papers, the measurement of paper capillary radius was realized. The distribution of ink pressure obtained by this method is much more close to the practical distribution of ink pressure between two contact printing rollers, and the calculation precision of printing ink permeating depth in porous papers was improved. This new method is useful for studying infiltration of printing ink and the influence of capillary radius on printing quality. |
