Xerox Disclosure Journal
The present disclosure relates to ink jet printing and in particular, to a droplet excitation technique which facilitates controlled application of charge onto ink jet droplets. Referring now to the figure, there is illustrated a droplet generator 1 having a nozzle 2 directing a column or stream 3 of ink toward a recording medium 4. It is possible to impart a localized disturbance to the column 3 such that a single droplet 5 breaks off earlier in the column than other droplets 6 surrounding that drop. The single droplet 5 is charged differently than the other droplet 6 enabling an encoding of information and non-synchronous ink jet operation.
