In inkjet imaging, in order to obtain high image quality, it is desirable to quickly solidify ink droplets on the media. In order to understand the speed at which the ink droplets solidify, the process was quantified by measurement based on the dynamic light scattering method. In addition, the phenomenon of ink penetration into media, which is one of the factors of solidification, was visualized by the method of optical coherence tomography, and the interface movement speed was quantified. These make it possible to determine whether the ink droplet behaves properly for image quality.
