Ink monitoring: Using sound velocity, density, and viscosity to improve ink quality
Both the technical specifications of the printer and the characteristics of the ink used are crucial for optimizing the printing process. Monitoring ink composition can be achieved by measuring density, sound velocity, and viscosity.
Anton Paar provides the ink industry with numerous measuring instruments to ensure the quality of ink and to support the developments of new ink formulations. One possible combination is a system comprising both a combined density and sound velocity meter and a rolling-ball microviscometer.
Knowing the density, the sound velocity, and the viscosity of ink is of great importance for ink producers because these physical properties provide important information on quality and usability of the raw material and the final product. Especially sound velocity measurements on ink represent an easy way to check on the purity of the raw material and the resonance homogeneity of ink. The flow properties of ink and the droplet size and formation are strongly affected by the ink’s viscosity.
