jet printing heads. SUBSTANCE: the device contains a great number of parallel channels, each separated from the adjacent channels by side walls capable of moving in the transverse direction in response to the control signal. The cross interference depending on the printing scheme is eliminated due to application to the channel selected for switching of a signal maintained at the given zero ;eve; during a period, whose duration exceeds the duration of the period at which the speed of the drop ejected from the mentioned selected channel essentially does not depend on the fact whether the channels near the mentioned selected channel for ejection of drops simultaneously with ejection of drops from the mentioned selected channel are switched on in the same manner. EFFECT: enhanced quality of printed image. 6 cl, 15 dwg |
