Viscosity change of model ink liquid film during drying process

Abstract

It is important to analyze the ink evaporation mechanism to improve the printing speed of commercial inkjet printers. Whether or not the solid components are internally dispersed can be determined by measuring the change in viscosity of the liquid. In this study, we constructed a device to measure the damping constant of a liquid film and actually measured the change in viscosity of a model ink in an aqueous system. As a result, it was confirmed that the damping constant was actually decreasing.
