Abstract
An image processing apparatus for printing an image on a print medium by using a printing unit that ejects a first ink in accordance with first quantized data and ejects a second ink in accordance with second quantized data, the image printing apparatus has a first quantization configured to quantize multi-valued data corresponding to the first ink to generate the first quantized data, the multi-valued data indicating intermediate density; and a second quantization unit configured to quantize multi-valued data corresponding to the second ink to generate the second quantized data, the multi-valued data indicating intermediate density. Surface tension of the first ink is larger than surface tension of the second ink, and a first dot pattern printed on the print medium in accordance with the first quantized data has higher dispersibility than a second dot pattern printed on the print medium in accordance with the second quantized data.
