摘　　要：应用流体体积法,对非牛顿流体油墨的凹版胶印油墨转移的第2阶段进行了数值模拟,以研究油墨在网穴与橡皮布之间的转移。通过模拟结果,分析了油墨与平板及梯形槽壁的接触角、网穴深度对油墨转移率的影响,并提出了可获得最大油墨转移率的接触角组合。Fluid volume method was applied to simulate non-newtonian ink transfer in the second stage of gra- vure offset printing to study ink transfer from ink cell to rubber blanket. According to the simulation results, the influence of ink cell wall contact angle, plate contact angle and ink cell depth on ink transfer rate was ana- lyzed. The contact angle combinations for the largest ink transfer rate were put forward.
