摘要： An image printing apparatus prints image data using a plurality of printheads each having a plurality of printing elements. A density correction signal calculation unit calculates a density correction signal on the basis of a correction parameter set in accordance with a printing element positional relationship between the plurality of printheads in the array direction, and the signal value of at least one pixel adjacent to the switching position of image data from the printing element of one printhead to the printing element of another printhead at an adjacent portion between the plurality of printheads. A quantization unit quantizes the density correction signal into a quantized density correction signal. A correction signal printing unit forms at least one print dot adjacent to the switching position of a line including at least one pixel or a neighboring line on the basis of the quantized density correction signal.
