Inkjet Drying & Curing
Hardware & Chemistry for fixing inkjet Inks
Thursday 13 - Friday 14 June, 2019
Møller Centre, Cambridge, UK
COURSE FOCUS
The Inkjet Drying & Curing course covers all of the necessary hardware and ink chemistry for fixing inkjet inks. The course covers drying of aqueous and solvent inks, comparing different possible methods and including near-infrared (NIR) drying, ultra violet light (UV) curing and electron beam (EB) curing. Course presenters include Adphos and Phoseon, with further speakers to be confirmed.
The drying section reviews the ink drying process, including adhesion, penetration into the substrate, rub resistance and print quality. The differences in behaviour on porous and non-porous media are discussed. Wavelength, absorption characteristics of inks, typical substrates and coatings are also covered. The advantages and disadvantages of potential ink drying techniques are reviewed.
The course gives an in-depth introduction to the UV curing process and its relevance to digital inkjet printing. The course introduces the fundamental chemistry and hardware required, assessing the pros and cons of each type available on the market. The emerging technique of EB curing will also be introduced, and its potential advantages reviewed.

Dr Tim Phillips, Founder & Director
Catenary Solutions, UK
Tim Phillips has extensive experience in challenging inkjet integration projects, spending eight years working at Xennia Technology Ltd, the leading inkjet solutions company that was acquired by Sensient in 2015. This involved working with a wide range of companies developing technology for new applications including textiles, ceramics, packaging, décor and functional material deposition for printed electronics and biomedical uses. Tim founded Catenary Solutions in 2015 to bring this knowledge of digital solution development and marketing to a wider audience. Tim has also presented IMI Europe courses in the past including the Inkjet Academy and Inkjet Ink Manufacturing & Digital Textile Printing courses.
Mikala Baines, Applications Development Specialist & Business Development Manager
ebeam Technologies, Switzerland
Mikala Baines has nearly thirteen years of experience working in the printing industry. Most of these years were dedicated to developing her career in formulating UV inkjet inks for various applications at Fujifilm Speciality Ink Systems in the UK. In this time Mikala also studied part-time to acquire her BSc in Chemistry with the University of Greenwich and the Open University. Drawn to the potential of electron beam curing in the printing world, Mikala moved to Switzerland in March 2017 to join the dynamic team at ebeam Technologies. She currently works as an Applications Development Specialist, collaborating with a wide range of companies to research solutions for their businesses as well as evaluating new possibilities for the technology.
Dr Stuart Palmer, Sales Manager
IGM Resins, UK
After obtaining a degree and PhD in Chemistry (University of Kent, Canterbury, UK), Stuart worked in UV-curing technology at Autotype and Fujifilm SIS (then known as Sericol). He then spent 10 years working in chemical distribution, which exposed him to many other coating technologies. He joined IGM Resins, a company dedicated to producing raw materials for UV curing, in 2008.
