Inkjet Ink Characterisation

Viscosity, dispersions, jetting & surfaces

Wednesday 13 - Thursday 14 June, 2018

Novotel Gent Centrum Hotel, Ghent, Belgium

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 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.

Live Demonstrations

As part of the course, there will be demonstrations using a JetXpert drop visualisation system - your chance to see the system in action.

    COURSE LEADERS

    Dr Adrian Hill.jpg

    Dr Adrian Hill, Product Technical Specialist
    Malvern Panalytical, UK

    Adrian obtained his PhD from the School of Chemistry at the University of Exeter, where his work involved rheological studies on high particle-loaded dispersions. Adrian also has industrial experience from Sun Chemical, where he worked to formulate and evaluate a range of inks and electronically-functional coatings. His extensive involvement with rheology measurements  across multiple application sectors has been gained from over fifteen years working as a rheologist, first with Bohlin Instruments, and subsequently with Malvern Instruments, supporting customers working with both rotational and capillary rheometers. With a strong technical understanding of rheometers, Adrian helps users to get the most out of their instruments by optimizing their rheological measurements. Working with Malvern Panalytical’s complementary particle characterization technologies has enabled Adrian to use his background to focus on the properties of dispersed systems – from suspensions and emulsions through to pastes and gels – and help customers understand how the bulk rheology of their materials can be controlled by the properties of the constituent components.

    Dr Sarennah Longworth-Cook, Product Technical Specialist - Laser Diffraction
    Malvern Panalytical, UK

    Sarennah Longworth-Cook has a PhD in Materials Science from the University of Cambridge. After graduation, she spent 9 years working in particle characterisation labs for multinational manufacturers of fine chemicals, catalysts and foods. She has experience in a wide range of analytical techniques, including electron microscopy, surface science, electron and X-ray spectroscopies, and particle size analysis. Sarennah joined Malvern Panalytical in June 2014 in the role of Product Technical Specialist – Laser Diffraction. She provides high-level technical support across the business, to users, product management, marketing and sales functions. Her main focus is ensuring users are empowered to make high quality, meaningful measurements of particle size. Sarennah’s favourite application is chocolate.
