Abstract

While screen- and pad printing techniques have been established for a long time the automation potential in these fields is limited and the processes require high amounts of manual labor. Piezo inkjet technologies are recently advancing to open possibilities for the use of high-viscosity materials. One potential material class could be screen printing inks that are already established in graphical and functional printing. However, even with the viscosity of these material classes now covered by new printhead technologies the process of implementing a new material for a piezo inkjet process is more complex. This study is outlining the workflow to evaluate a new high-viscosity material for piezo inkjet printing and shows first results for the implementation of two widely used and commercially available screen-printing inks.
