Abstract
An on-demand-type ink jet recording apparatus and process wherein the droplet size is controlled to effect halftone-gradiation recording. A preceding pulse is applied to the electromechanical transducer prior to the main pulse so as to control the position of the ink meniscus in the nozzle and thereby control droplet size.
