Inkjet Drying & Curing

Hardware & Chemistry for fixing inkjet Inks

Thursday 30 - Friday 31 January 2025

Hotel Primus Valencia, Valencia, Spain

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, Catenary Solutions and Sherkin Technologies.

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.

Alan Mills, Sales Manager UK, Ireland and Scandinavia
Phoseon Technology, UK

Alan Mills first started working in the printing industry in the 1980’s.  His first position commenced as an engineer dealing with coding and marking machines for a wide range of industries such as FMCG, Aerospace, Aircraft, Pharmaceutical and Graphic Arts.  Alan has been selling UV systems for over 30 years in the following markets: - Digital Inkjet, Narrow Web Flexo, Sheet Fed Offset, Fibre Optics, Wood Coatings, Automotive, Medical and has been working for Phoseon (now part of Excelitas) supplying UV LED systems for the past 6 years.

Dr Stuart Palmer, Business Owner
Ibis Innovation, 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. Stuart worked at IGM Resins, a company dedicated to producing raw materials for UV curing, for 15 years before starting his own venture, Ibis Innovation.

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, working with numerous companies in the inkjet industry since then.
