| 摘要 |
The invention relates to a process for compensating for effects related to variations in the velocities of electrically charged ink drops (40) in a jet (4) output from a print head of a printer, the drops being electrically charged by charge electrodes (30), consisting of : - measuring the velocity of the jet on the downstream side of a drop charge zone, and calculating a variation in this measured velocity, - for each drop, determining a voltage correction value to be applied to the charge electrodes, as a function of said measured velocity variation. |
