11. Strobe User Interface Select single, double or triple drops Start or stop the strobe Set delay times, pulse width, change shutter speed and intensity. Visualize droplets in motion by using variable delay times. Choose firing mode and trigger type Automatically save image to file Close the GUI window

12. Theory of Operation Print head drive frequency or internal frequency Strobe pulse width Strobe intensity Delay 2 Delay 1

13. Single Strobe Event Single event image of single droplet (left) vs. 4 drop aggregated droplet image (right). Both images were taken with a strobe pulse width of 500ns. Single droplet 4 droplets Images from Kodak print head, #10 cartridge.
