Abstract

To understand and predict the process of formation of image structure in inkjet printing system, simulation models to calculate drying and penetration behavior were developed. The drying behavior is calculated by considering evaporation from surface cell and diffusion caused by concentration distribution between neighboring cells, and it becomes possible to predict detailed dynamics of ink consisting of multiple liquid components and solid particle. The penetration behavior is calculated by solving pressure distributions in median pore structure to satisfy relationships between Laplace pressure and flow resistance. Then penetration behavior in media that has multiple pore structure such as coated paper is predicted. By using the simulation models, the mechanism of “smudge” phenomenon due to image fixing strength that is determined by image forming process including drying and penetration behaviors is clarified.
