摘要： An ink-jet recording method which hardly causes ink to blur. To this end, there are provided a correction table (30) which contains the number of ejection ink dots of each color limited in advance according to the combination of the numbers of ejection ink dots instructed for respective colors in a unit area in such a way that the total number of ejection ink dots does not exceed a predetermined limit value, and an error table (31) which contains the errors which may be produced when determining the limited numbers of ejection ink dots of the colors and which are previously calculated and determined according to the combination of the numbers of ejection ink dots instructed for the colors in the unit area. Before printing, a corrected number of ejection ink dots for each color in each unit area is determined from the correction table (30) according to the combination of the numbers of ejection ink dots on which each head is instructed based on binary image data (S25). At this time, the errors listed in the error table (31) are accumulated for every unit area (S27), the integer part, if appears in the accumulated value, is made to affect the numbers of ejection ink dots, and the accumulated error is updated (S25).
