Visualization and Analysis of Drops in Flightwww.jetxpert.com 5. Why Analyze Drops In-Flight? Visualize Drop Formation- Adjusting jetting parameters and ink formulation to optimizedrop formation means faster turnaround and cheaperdevelopment. It also removes added complications fromsubstrate interaction. Test Sustainability- The ability to test jet sustainability both automatically andoffline, saves both time and money. 30% of printer failures aredue to jet out. Diagnose Misting- Usually less important for graphics, but critical for printed circuitboards and other printed electronics applications.www.jetxpert.com 6. Why Analyze Drops In-Flight? Verify Nozzle-to-Nozzle Consistency- Some heads, like the SX3 from Dimatix, feature individuallyaddressable nozzles. In these cases, in-flight drop analysis canbe used to optimize individual nozzle voltages, for highlyconsistent performance across the head. Wetting- High magnification cameras identify wetting problems in earlystages of development. Measure Drops- For many applications, a particular drop volume or velocity isrequired. Jetting parameters and ink formulations may beadjusted until in-flight analysis shows that the desiredcharacteristics have been achieved.www.jetxpert.com 7. Case Study A few years ago, a prominent ink company with over 1000employees sought to develop jetable metallic inks, for a varietyof decorative applications. Initial print testing was favorable, but as testing continued, printelectronics boards began blowing out at an alarming rate. High resolution, live video of the nozzle plate during jettingshowed that significant misting was occurring. This ink mist hadbeen building up on the electronics, and causing electricalshorts. Live video of drop formation allowed new ink formulations andjetting parameters to be tested far more rapidly andinexpensively, until the misting problem was eliminated. The new inks passed QA and sustainability tests, andsuccessfully reached market.www.jetxpert.com 8.
