SOLUTION SHEETIDS - Inkjet Droplet Sizer
Droplet measurement solution for inkjet printing quality control

The ultimate tool for inkjet printing, monitoring, calibration and control
New applications of inkjet printing of miniature electronics, OLED display printing,printing of sensors etc. require extraordinary accuracy, precision and control of droplet
size, velocity, and position to meet the demands. Typically, every nozzle needs to bechecked after a run with a minimum downtime to assure the final product meets specs
before wasting time and material on a failed run. The IDS has been developed to meetthese strict requirements
This non-intrusive optical measurement solution provides real-time results ofdiameter, velocity, and direction of each droplet ejected from every one of thepotentially thousands of print head nozzles. This on-the-fly information creates
input/data to guide the optimization of the ejection process parameters. As an
integrated part of your inkjet printing process, our solution helps you to create andmaintain a stable, high-quality printing that allows you to exploit the full potential ofyour inkjet-printing setup.

Key benefits Fastest droplet measurements minimizes production down-time Real-time measurement of droplet characteristics Data on droplet size (diameter and volume), velocity and trajectory Droplet volume/size down to 0.0005pl/1 µm and velocity up to 100+ m/s
 Ultra-high resolution and precision of measurement results

The solution in brief
The IDS provides online, real-time information on droplets ejected from the nozzles inmodern inkjet printers with the best resolution and accuracy commercially available.
The real advantage it is that the solution can be used for effective monitoring,calibration and control of the inkjet-printing process thereby securing a smooth
operation of the printing production line and a continuous high printing quality that all
together reduces the production scrap volume/value.

IDS solution: high performance processor, measurement software and IDS unit,

Quantitative droplet characteristics measurement
The measurement system consists of a sealed optical unit allowing rapid measurementof print heads, in combination with a high performance processor and advanced, yetuser-friendly measurement software. Signal processing via the high performance
processor provides real-time measurements of each single droplet with up to 100,000
droplets per second. The processor and software can be customized to meet theunique requirements of your inkjet printing system platform/software.
Real-time measurement ofdroplet characteristics allows
quality control of the inkjet
printing application

The solution provides online, real-time characteristic information as droplets areejected from the nozzles. The measurement resolution is better than 0.1 µm, making it
able to detect the subtle differences from drop to drop during the jetting process. Thisultra-high resolution and precision of the IDS in combination with the accuracy andPAGE | 2

stability of the instrument have been welcomed and approved by the particle anddroplet measurement community.

The IDS solution helps optimizing the inkjet printing process of OLED-displays

Higher printing quality & reduced downtime
The acquired real-time information on droplet characteristics can be used for controlling nozzle settings. Corrective actions can be implemented at an early stage tooptimize the production performance and output quality, removing the need for costly
shut-downs of printing lines for calibration purposes. Also, continuous monitoringhelps identify and rectify droplet characteristics which are out of tolerance early onthat otherwise would have led to a poor quality production batch – reducing waste andprocess costs.
