Inkjet Training

This two-day lab course takes you from ink rheology and material pre-screening through printhead selection, dropwatching and printing trials to curing, troubleshooting and transfer to your own use cases. Experienced tutors from Fraunhofer Institute for Manufacturing Engineering and Automation, and from Hahn-Schickard combine focused theory sessions with hands-on lab demonstrations, guiding you in assessing new inks, matching them to substrates, and identifying and resolving typical jetting and process issues.
