Printing control apparatus and printing control method

摘要

A printing control apparatus configured to use a recording head where a plurality of nozzles are arranged in a row formation to discharge ink droplets from each of the nozzles by individually supplying predetermined driving power with regard to actuators, and configured to discharge the ink droplets with different discharge speeds so that subsequent ink droplets catch up with and combine together with prior ink droplets that are continuously discharged before the prior ink droplets land on a printing medium. The printing control apparatus includes a control section configured to drive the actuators in the recording head so that dots that are in a region where a nozzle usage rate is higher than a predetermined threshold are printed due to ink droplets, where ink droplets that are continuously discharged combine together in air, attaching to the printing medium.

1. A printing control apparatus configured to use a recording head where a plurality of nozzles that respectively link with predetermined ink paths are arranged in a row formation to discharge ink droplets from each of the nozzles by individually supplying predetermined driving power with regard to actuators that are respectively arranged in the ink paths, and configured to discharge the ink droplets with different discharge speeds so that subsequent ink droplets catch up with and combine together with prior ink droplets that are continuously discharged before the prior ink droplets land on a printing medium, the printing control apparatus comprising:
a control section configured to drive the actuators in the recording head so that dots that are in a region where a nozzle usage rate is higher than a predetermined threshold are printed due to ink droplets, where ink droplets that are continuously discharged combine together in air, attaching to the printing medium, the control section including a nozzle usage rate acquiring section that is configured to acquire a usage rate for a plurality of nozzles that are arranged in a row formation in each predetermined region per unit of time as the nozzle usage rate.
