ABSTRACT:
A print-distortion compensating apparatus and method for an improved electrostatic type ink jet printing apparatus including a print-distortion compensating means, in which the compensating amounts for the print-distortion due to the influence of the neighboring ink droplets, such print-distortion being variable depending on the respective deflection steps, for instance, the print-distortion caused by the variation of aerodynamic resistance due to the preceding ink droplets, the Coulomb's force due to the preceding and subsequent charged ink droplets, and the charge induction due to the preceding charged ink droplets are memorized into and read out from the afore-mentioned print-distortion compensating means and those are finally added to or not added to the basic charging codes depending on presence or absence of the PRINT data on the ink droplets adjacent to an ink droplet to be charged.
