| 摘 要： | 接触印刷分为2个不同的阶段:压印过程和自由渗透过程。采用渗流理论优化了接触印刷加压过程中油墨的渗透深度,避免了Olsson方程对毛细管半径的简化。自由渗透阶段,考虑到了动态接触角随动态接触线速度变化的因素,采用了动态润湿方程使得油墨的自由渗透深度计算更为准确,最后采用分形理论完成了毛细管半径的计算,进而完成了油墨渗透深度的研究。

| Abstract: | There are 2 processes during contact printing,press printing process and free permeating process.The ink permeating depth during press printing process was optimized using seepage theory to avoid simplification of capillary radius with Olsson equation.Dynamic wetting equation was applied to get permeating depth during free permeating process considering dynamic contact angle changing with dynamic contact line velocity.The capillary radius was calculated by using fractal theory. |

| Keywords: | ink and paper permeating depth capillary radius fractal theory |
