Why Analyze Drops In-Flight?
• Visualize Drop Formation
- Adjusting jetting parameters and ink formulation to optimize
drop formation means faster turnaround and cheaper
development. It also removes added complications from
substrate interaction.
• Test Sustainability
- The ability to test jet sustainability both automatically and
offline, saves both time and money. 30% of printer failures are
due to jet out.
• Diagnose Misting
- Usually less important for graphics, but critical for printed circuit
boards and other printed electronics applications.

6. www.jetxpert.com
Why Analyze Drops In-Flight?
• Verify Nozzle-to-Nozzle Consistency
- Some heads, like the SX3 from Dimatix, feature individually
addressable nozzles. In these cases, in-flight drop analysis can
be used to optimize individual nozzle voltages, for highly
consistent performance across the head.
• Wetting
- High magnification cameras identify wetting problems in early
stages of development.
• Measure Drops
- For many applications, a particular drop volume or velocity is
required. Jetting parameters and ink formulations may be
adjusted until in-flight analysis shows that the desired
characteristics have been achieved.

Adding Greater Capabilities
• Automation (motion)
– Enables sequential step and repeat
measurement along an entire print head
• Face-plate wetting visualization
– Second camera for visualization of face plate
wetting during firing
• Frequency sweep
– Automatically step through a series of user-
defined frequencies and assess print head
performance
• Ink supply system
– Active gravity meniscus control: meniscus level
remains constant while printing
