Abstract
First quantization data for printing by the first nozzle group and second quantization data for printing by the second nozzle group are generated based on multi-valued data. By use of mask patterns, first print data and second print data are generated based on the first quantization data and the second quantization data. The first mask pattern for generating first print data and the second mask pattern for generating second print data are formed so as to include a pixel in which printing of a dot is allowed in both and a pixel in which printing of a dot is not allowed in both. The pixel value of each pixel indicated by the multi-valued data has a correlation with the sum of the number of dots indicated by the first print data and the number of dots indicated by the second print data in the area corresponding to each pixel.
