Abstract: In this paper,the finite element simulation software Ansys Workbench was used to simulate the influence of ink roller speed in the ink temperature field during the printing process. Different ink roller speed the influence of the temperature of the ink flow field,the temperature change trend of the surface ink and the extrusion area ink was analyzed. And the experiment platform of ink printability tester was used for experimental verification of simulation analysis. Using the infrared thermal imager,the ink temperature field cloud picture of different time and the ink temperature at real-time data of extrusion area were obtained respectively. Finally through the contrastive analysis of the experiment and simulation,the effect of ink roller speed on the printing ink temperature field was obtained. When the pressure between the two rollers keeps constant,the ink roller speed has larger influence on the ink temperature in steadystate,without considering the new ink inflow and high temperature ink outflow,the ink temperature at extrusion area increases with increase of the ink roller speed.
