1. An ink-jet printing method of performing a plurality of main scanning operations of an ink-jet printhead for discharging ink with respect to the same print area and completing printing on the same print area by the plurality of main scanning operations, comprising: the printing step of performing multilevel printing by changing the number of ink droplets discharged to each pixel in the plurality of main scanning operations, wherein in the printing step, multilevel printing is performed such that the number of scans performed to discharge ink droplets used to print a pixel with a low gray level value is made larger than the number of scans performed to discharge ink droplets used only to print a pixel with a high gray level value.
