Corinna Little and Andrea Werkmann explain how the latest plasma pre-treatment can optimise printing by improving adhesion of inks and coating, even on challenging surfaces
Atmospheric pressure plasmas generated by electrical discharges in air or other gases have a remarkable combination of properties that enable unique surface treatment.
Such plasmas produce large quantities of very reactive but short-lived chemical species.
These can disinfect, clean, modify and functionalise a wide range of surfaces and prepare them for bonding, painting and printing.
In recent years, plasma pre-treatment has established itself as a standard process in many different sectors, from medical technology and the automotive industry to aerospace and aviation technology…………
