An image processing apparatus inputs a plurality of multi-valued data corresponding to a plurality of color materials, and quantizes each of the plurality of multi-valued data and generate a plurality of quantization data each indicating recording or non-recording of a dot on a recording medium by each of the plurality of color materials. A plurality of dot patterns of the plurality of color materials recorded based on the plurality of quantization data generated have peaks at different deviation angles in power spectra in a frequency domain and have blue noise characteristic or a green noise characteristic.
