To obtain high-quality image with an inkjet printing process, it is important to control wetting and coalescing behaviors of minute droplets. Therefore, development of a simulation technology to predict these behaviors has been demanded. In this study, we focused on MPS simulation method that has the advantage in free surface analysis, and implemented a newly developed potential model for surface tension and an algorism for ink surface determination. By this MPS simulation, wetting and coalescing behavior from hydrophilicity to water repellency has been quantitatively reproduced, and the prediction of the image defects such as cyclic wavy line became possible.
