摘　　要：针对印版图文覆盖率对墨层厚度及着墨率的影响进行了研究。建立了油墨转移模型、印版图文覆盖率与墨层厚度及着墨率关系的数学模型。在油墨转移率等于0.5的条件下,通过对输墨系统的离散化处理,实现了连续的输墨系统的计算机仿真分析。计算结果表明,同一输墨系统的墨层厚度与着墨率在稳定状态下并不是固定不变的,它们与印版图文覆盖率密切相关。同时,墨辊上墨层厚度及着墨率的变化与输墨系统的墨辊数量及排列方式均存在一定关系。A transfer model and a model which calculates the steady state ink film thickness in an inking system as a function of coverage percentage was developed. The method used computer simulation and the model predictions assuming a 0.5 split ratio, It was shown that ink thickness distribution highly depends on coverage percentage. In deferent inking system, the ink thickness distribution and the ink flow ratio is different for the deference of the number of roller and the arrangement of the roller.
