Inkjet Ink Characterisation
Viscosity, dispersions, jetting & surfaces
Monday 8 - Tuesday 9 April, 2019
Crowne Plaza Hotel - City Alster, Hamburg, Germany
Development of high quality inks and fluids for inkjet applications requires state-of-the-art characterisation equipment and techniques. From fundamental ink properties such as viscosity and surface tension, which have a crucial impact on jetting performance, through analysis of particulates dispersed within the ink, understanding these properties is key to getting the best out of an ink development project. In addition, it is vital to understand how the developed ink actually behaves, both on ejection from the printhead and when landing onto the substrate of choice.
The Inkjet Ink Characterisation course gives an excellent introduction to these essential areas of study, presented by industry experts from leading suppliers and institutions in the field. The course will give you the basic foundations as well as a more detailed understanding of the vital equipment and techniques.
As part of the course, there will be demonstrations using a JetXpert drop visualisation system - your chance to see the system in action.
