Inkjet printing system, printed electronics, jetting behavior measurement.
As inkjet printing technology becomes more common as a manufacturing tool for printed electronics, the
inkjet printing process for a specific application needs to be fully tested and optimized. To optimize the printing
inkjet process, printed patterns on a substrate, or the measured jetting performance from charge-coupled device
(CCD) camera images of ink droplets, are often used for ink and printing algorithm development. However, a
commercial inkjet printing system might not be completely flexible for inkjet process development or ink
development. As a result, operators of commercial inkjet printers might find it difficult to modify hardware
systems and printing algorithms according to their specific applications. Therefore, we developed an in-house
inkjet printing system for printed electronics which is flexible with respect to both hardware and software
Figure 1 shows the hardware for our inkjet printing system. The printable area is 240x270 mm2. Head fixtures
and software were developed such that two different heads (SE-128 from Dimatix and MJ-AT-01 from Microfab)
can be used. Other commercial heads can be integrated with our printing system by modifying or replacing the
head fixture and head driving electronics.

printing software to simplify our software d
