Research on the Visualization Process of Ink Droplets Infiltrating and Diffusing in the Substrate in Inkjet Imaging System
In the inkjet imaging system, the printing imaging pressure of ink droplets in the substrate comes from the droplets kinetic energy after jetting, therefore, the initial pressure of the ink droplets infiltrating and diffusing in the substrate is derived from the conversion of ink droplets kinetic energy, this also directly affects producing the dot gain phenomenon in the inkjet printing. The movement process of ink droplets flying and infiltrating in the substrate was researched in this paper by using the mathematical model of the discrete-phase ink droplets flowing in the porous media based on the CFD (Computational fluid dynamics) method and the advanced experimental instruments. The results were shown by visual graph. Secondly, the imaging results of the ink droplets in the paper coating were analyzed in this paper by using QEA image analysis instrumentation, the simulation results and experimental results showed that the imaging process of ink droplets in the substrate could be represented by the mathematical model of the discrete-phase fluid flowing in the porous media, these results described the underlying causes of the inkjet imaging dot gain and provided a scientific theory in order to solve the dot gain problem in the inkjet imaging printing system.
