In order to improve the printing quality and know the process of ink transferring well, ink flowing among ink rollers is simulated by using CFX. Firstly ink transferring characteristics between two rollers are analyzed. An experiment is carried out to test the accuracy of this simulation analysis. Then ink transferring characteristics among three and five rollers are analyzed respectively. The general characteristics of ink transferring among rollers are got by comparing the velocity of ink flowing, ink pressure and ink transfer ratio from those simulations. What is more, the accuracy of the simulation analysis is verified by experiment. And this research provides a reference to general characteristics of ink transferring in the actual printing process, and its important for the printing color quality control and has a better application prospect.
