The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked at a different temperature. The ink of the digital print consists of two parts of the pigment and solvent. In this article, the effect of pigment and solvent additives has been investigated as the main factors affecting the physical properties of digital ink. The results of this study indicate that pigment is known as the main component of the physical properties of digital ink. The amount of pigment in ink can have a definite effect on density, viscosity, and surface tension while its effect on surface tension is lower than other properties.
