Inkjet Drying & Curing
Hardware & Chemistry for fixing inkjet Inks
Thursday 9 - Friday 10 July, 2020
Online Course
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 as well as the curing of monomer-based inks. Different possible methods are reviewed including near-infrared (NIR) drying, ultra violet light (UV) curing and electron beam (EB) curing. Course presenters include Adphos, Phoseon and IGM Resins.
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.

COURSE LEADERS
James Burbidge, Technical Director Europe - Print Technology
Adphos Innovative Technologies, Germany
James has had much experience in his ten years in the digital printing field, working both as a key technical trouble shooter for a market leading manufacturer of digital colour presses, and as technical lead in a large printing company responsible for the development of digital production. He now brings that experience to bear enhancing the performance & productivity of production lines by integrating Adphos technology into the process, thereby increasing performance and flexibility.
Rob Karsten, Regional Director EMEA
Phoseon Technology, USA
Rob Karsten is the Regional Director EMEA for Phoseon Technology, the world leader in UV LED technology. He has been with Phoseon pretty much from the beginning and has been responsible for building their business in Europe. Rob was born in Canada to Dutch parents and holds a degree in mechanical Engineering.
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.
Dr Tim Phillips, Founder & Director
Catenary Solutions
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.
Tim graduated from the University of Cambridge with an MA Honours degree in Natural Sciences, and completed his PhD in liquid crystal physics and chemistry at the University of Bristol. More recently he studied for an Executive MBA at the University of Warwick.
