Uniform inkjet printing is restricted by many factors，including the pressure wave，droplet physical properties （viscosity，surface tension，etc.），and nozzle diameter. The numerical model based on volume of fluid is established for deeply understanding of droplet spray process. Based on numerical simulation，the stability influence of the driving voltage amplitude andthe silver ink of low viscosityare studied. 27μm nozzle diameter of industrial nozzle is used to construct inkjet system，it experiments the silver inks inkjet on glossy paper and verifies the numerical model. The results show that the droplets velocity depends on the driving voltage amplitude，droplet diameter distribution and satellite droplet generation depend on the droplet velocity. It plays an important role on the industrial application of inkjet printing.
