<p>Deflection electrodes (90, 92) create a region of high electric field intensity and an ink mist neutralization region (96). High field intensity is achieved by spacing the deflection electrodes (90, 92) closer together than has hitherto been possible. The higher deflection field intensity facilitates full ink drop deflection and character size although the effective length of the electrodes (90, 92) may be substantially less than those in conventional ink jet printing heads. Insulative material (94) is placed over the high voltage deflection electrode to obviate high voltage arcing. The insulated electrode and the ink drops to be deflected may be of the same polarity permitting an ink mist neutralization region (96) to be located on the low voltage electrode (90).</p> |
