ABSTRACT OF THE DISCLOSURE Printing distortions caused by ink stream/charge tunnel misalignment, charge tunnel mis-dimensioning or a variation in drop spacing or changes in ink resistivity are corrected by measuring the actual induction co-efficients for a particular printer. For this purpose, charge sensors located along the ink stream or adjacent the ink catcher detect induced charges from which the induction co-efficients are calculated by a programmable controller. These co-efficients are used to adjust the charge tunnel voltages to reduce or eliminate printing distortion.
