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