Method of controlling piezo elements in a printhead of a droplet generator |
摘要 |
The printhead has a multitude of adjacently arranged channels with piezo-electrical shear converters. The impulse form for activation of the converters-depending upon the number of simultaneously activated neighboring channels-is changed in such manner that the exit velocity of the ink droplets is constant. This makes it possible to obtain a better print image.
