Inkjet Ink Characterisation Practical Course
Viscosity, dispersions, jetting & surfaces
17-20 April 2023
Meteor Inkjet Laboratory, Harston, Cambridge, UK
COURSE FOCUS
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 Practical course gives an excellent hands-on introduction to these essential areas of study, presented by industry experts from leading suppliers in the field. The course will give you the basic foundations as well as a more detailed understanding of the vital equipment and techniques, while allowing you to understand how the key characterisation equipment works and see it in action.
The course also allows you to bring your own ink samples and get the resident experts to help you with particular characterisation problems you may be having.
