Abstract
The ink flight of electrostatically extracted ink jet was observed by He-Ne laser and an Application of this ink flight to tone reproduction is also described in this paper. Dielectric ink was used.
Ink is presumed to be in flight in the form of liquid thread at the nozzle tip and ink corpuscules beyond the region of ink thread. A liquid thread means a continuous flow of ink. In the region beyond the zone of liquid thread, ink corpuscules are generated randomly.
He-Ne laser made possible phtographing both an ink thread and the transition of ink jet beyond it in a picture. In analysis of the ink flight, the spread of ink and transition of ink jet were clarified by image processing concretely. Furthermore, we have proved that this transition of ink jet can be applied to tone reproduction.
