Inkjet ink viscosity is a complex topic requiring specialist equipment and techniques to characterise fully. Viscosity is a key parameter mediating drop formation as well as substrate behaviour so is vital to understand in ink development. Mats Larsson from Malvern Instruments will describe the use of characterisation equipment to measure the rheological behaviour of inkjet inks at the IMI Europe Inkjet Ink Development Conference in Lausanne, Switzerland, 15-16 March 2017.
Waveform generation and optimisation is a crucial but often overlooked aspect of inkjet development. ImageXpert’s presentation at the IMI Europe Inkjet Ink Development Conference in Lausanne, 15-16 March 2017, will give an overview of the tools and techniques that make waveform optimisation more streamlined and effective.
In order to exploit the potential of inkjet printing, better understanding of droplet behaviour, both in flight and on the substrate, is needed. Modelling is a good way of gaining insight into the phenomena which drive the different stages of the printing process. Jakko Nieuwenkamp of Reden will make a presentation based on this work at the IMI Europe Inkjet Engineering Conference in Lausanne, 14 March 2017.
This fantastic drawing was made by a colleague of Mike Willis while he was working at Cambridge Consultants in the mid-80s. It's a beautiful impression of how one version of continuous inkjet works, powered by a cyclist and a dodgy-looking chap with some bellows!
Nick Campbell of Inca Digital Printers describes the potential pitfalls of single pass inkjet printer design.
With inkjet printing rapidly proving itself as a true production process within the area of industrial printing, we as inkjet ink developers need to keep up with the pace and develop new fluids for these applications. Aqueous inks for industrial inkjet printing are potentially advantageous for many different applications. However, delivering the right functionality in a formulation with the constraints imposed by inkjet printing is no easy task.
Prof Cinzia Casiraghi, from the Graphene Centre, University of Manchester, discusses the formulation of inkjet inks containing 2D crystals and functional devices made using them. The work will be presented at the IMI Europe Inkjet Ink Development Conference in Lausanne, Switzerland on 15-16 March 2017.
Prof J. Frits Dijksman of the University of Twente explains the basic principles of fluid mechanics behind the operation of an inkjet printhead, comparing it with a musical instrument.
