<p>PROBLEM TO BE SOLVED: To provide a printing method capable of executing highly accurate printing, by accurately correcting an arrival position (an impact position) at a matter to be printed of a droplet discharged from a nozzle.SOLUTION: Trial printing is executed by discharging droplets from nozzles that constitute one nozzle array; a trial printing pattern formed by the trial printing is imaged; an impact position of a droplet from each of the nozzles that constitute the one nozzle array is arithmetically processed; if there is positional deviation between the impact position and a target position of the droplet, correction of quantity expressed by aμm unit (a pixel value of a decimal point or less)corresponding to quantity of the positional deviation, is added in the direction for negating the positional deviation of the impact position from the nozzle, to printing position coordinate data on the droplet from the nozzle expressed by theμm unit that is numerical data of a real number; and after converting the corrected printing position coordinate data into image data expressed by a bit map, printing is executed by discharging droplets to a matter to be printed based on the converted image data.</p> |
