Abstract: A method for inkjet printing includes setting a target volume and a target concentration of ink discharged to a pixel, measuring a volume and a concentration of a liquid drop for each of nozzles, selecting first nozzle groups for achieving the target volume, from a volume pool of the liquid drop for each of the nozzles, selecting second nozzle groups for achieving the target concentration, from the first nozzle groups, selecting recipes by combining brightness trend lines, from the second nozzle groups, performing a printing simulation for each of the recipes to select a final recipe, and performing inkjet printing by using the final recipe.
