Inkjet 2017 - Characterization course

Controlling the performance of an ink is a complex optimization challenge. Understanding how features of the system, the dispersed particle size in particular, impact stability and behavior during each stage of the printing process is crucial for effective formulation.

Over the past 30 years, the use of commercial and industrial inks has changed substantially. In particular, the maturation of inkjet technology has revolutionized printing. From office printers through to industrial coding and marking systems, inks are now required to meet demanding performance targets, for a wide range of different applications.

Inks are complex dispersions or emulsions consisting of dyes or pigments, and other components, suspended within a continuous phase. Formulation is complicated by the fact that the properties of these components impact multiple aspects of ink performance. For example, the particle size of a suspended pigment determines the hue, gloss and weatherability of the finished coating. At the same time it also affects the stability of the ink and its flow properties (viscosity). Ink formulation is an exacting science and relies on gathering relevant data from multiple analytical techniques to achieve an optimal solution.

Designer droplets – why the size and stability of inkjet inks matter

The IMI Inkjet Summer School addresses many of the formulation challenges cited above and much more. It is the ideal way to learn about key aspects of inkjet technology, from the basics through to more advanced aspects of the inks, printheads and applications. The event takes place from 12-16 June 2017 at the Novotel Gent Centrum Hotel, Ghent, Belgium.

As part of the Inkjet ink characterization session our own experts, Gérald Chabanis and Dr Steve Ward-Smith, will lead sessions on rheology and particle/dispersion assessment. Other technology experts will cover surface tension, drop visualization and print quality analysis.

Gérald Chabanis will present the Basic property measurements – rheology course at 09:00


  • Rheology – introduction
  • Basic techniques
  • Pros and cons
  • Theory of measurement
  • Rheology in action

Dr Steve Ward-Smith will present the Particle analysis course at 13:30


  • Particle analysis – introduction
  • Basic techniques
  • Pros and cons
