Ink-jet system comprising an ink channel (16) between an ink reservoir (14) and a nozzle (18), and an electromechanical transducer which comprises an expansible member (22) arranged adjacent to the ink channel for abruptly reducing the volume of the same in order to eject an ink droplet through said nozzle, characterized in that the depth of a portion (26) of the ink channel between the expansible member (22) and the nozzle (18) is larger than both the depth of the portion (24) adjacent to the expansible member and the height of the nozzle (18). <IMAGE> |
