Inkjet Drying & Curing

Hardware & Chemistry for fixing inkjet Inks

Thursday 15 - Friday 16 June, 2017

Novotel Gent Centrum Hotel, Ghent, Belgium


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, Phoseon, Ebeam Technologies 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.
