New IMI Europe inkjet course

‘Surface Treatment for Inkjet Printing’ will be held on 23 and 24 July, 2025 at the Moller Institute in Cambridge.

This course looks at the surface pre-treatment processes, including plasma and corona treatment, used to prepare the substrate for inkjet printing, leading to enhanced adhesion, print quality and durability. The course is led by Peter van Steenacker from Tigres and Kevin McKell from Vetaphone.

The two most common physical surface treatments are plasma and corona (dielectric barrier discharge) systems. These use different types of discharge technology to generate a plasma used to modify the surface. Plasma and corona treatment can remove contamination, increase wettability by changing the surface chemistry and, especially with polymers, improve adhesion by modifying molecular structure.

Both surface treatments can be used on a variety of substrates, including polymers, metals and ceramics. They are non contact processes that can be performed at ambient temperature and pressure, making them convenient and cost effective, and do not require any additional chemicals. The advantages and disadvantages of each process will be discussed.
