ABSTRACT:
An ink jet system printer of the charge amplitude controlling type includes a print control system for emitting printing ink droplets provided for forming a matrix pattern and interpolation ink droplets interposed among the printing ink droplets at a ratio, for example, 1/20. A counting system is provided for counting the number of printing ink droplets while a printer head travels a predetermined length. The counted number is compared with a reference number. In response to the comparison result, the interpolation dot ratio is varied in order to compensate for the variation of the travelling speed of the printer head.
