ESMA: New hands-on course – inkjet for glass applications

Where does surface tension come from? How long will pre-treatment last? How to achieve stronger ink adhesion? Which print head will best match a substrate’s shape? Frit or UV inks? Infrared, UV-LED or UV Mercury?

ESMA Academy on 14-16 November 2023 explains and reviews inkjet’s strengths in decorating various types of glass – container, flat, automotive…

During lab-based sessions participants experiment with pre-treatment methods, ink characterisation, print parameters, ink delivery systems, drying and curing mechanisms, print quality, drop and colour management.
