In order to improve the quality of colorful offset printing and know the process of ink transferring, this paper adopts the method of theoretical analysis and experiment, the velocity and pressure of the ink flow field are analyzed when the rubber roller deforms and the two rollers rotate, and the effective ink layer thickness is extracted, then the ink transferring rate can be got. The rubber roller’s deformation and ink transferring rate under different conditions are got, and factors, such as rotation velocity, deformation of rubber roller, ink layer thickness between two rollers, which affect the ink flow and transferring rate are analyzed.
