Abstract
An ink jet printing apparatus includes an ink condition detector for detecting a condition of ink. The ink condition detector produces outputs which represent a plurality of parameters of the ink. The parameters are the ink temperature, the ink pressure and the velocity of ink droplets in flight. A control device controls a charging device and/or a deflection device to compensate for a distortion in print position in accordance with an ink condition detected by the ink condition detector.
