PROBLEM TO BE SOLVED: To solve the problem in which an impact position deviation occurs and print quality is reduced due to the influence such as residual vibration in a pressure chamber if a discharge interval is shortened in inkjet printing which requires shortening of the discharge interval from a nozzle following increase in resolution and conveyance speed of a recording medium.SOLUTION: Uneven impact positions in a printing rear end on a recording medium due to an impact position deviation are corrected by additional liquid discharging. Since correct processing is directly performed on printing data by an arithmetic unit such as a computer, it is possible to make the impact position deviation difficult to be recognized with a simple configuration. For example, a correction printing pixel 605 is added to the printing data with the correction processing for additional liquid discharging.SELECTED DRAWING: Figure 14 |
