This paper describes the results of the first quantitative examination of ink flight peculiar to the electrically extracted ink jet method using dielectric ink. In the state of ink flight determined by this method, a continuous cylindrical liquid thread is formed at the nozzle tip, then the ink at the thread end turns into corpuscles and spreads out in mist. The author has already reported the method used for observation and the recording method for tone reproduction. In this paper, an examination was made of the details of average and instantaneous structures of the state of ink flight, covering the wide area from the nozzle tip to the area past the electrodes, and the effect of the state of ink flight on the recording for tone reproduction was studied on the basis of the examination results. Detailed examinations were made of differences in tone, density distribution, and the relation of nozzle diameter to liquid thread diameter and to corpuscle diameter by varying the applied voltages and ink pressures. The results indicate that the ink jet which scatters in an atomized state from the liquid thread is effective in application to a high‐quality recording for tone reproduction. © 1997 Scripta Technica, Inc.
