Abstract

A novel ionic surface preparation for nozzles used in spraying fluid droplets such as used in ink jet printers is disclosed. In conjunction with an oppositely charged ionic anti-wetting agent dissolved in the sprayed fluid, the new surface preparation reliably reduces the wetting of the nozzle surfaces, thereby facilitating the production of more uniform and predictable droplets.
