Abstract
An image processing apparatus has an acquisition unit configured to acquire first multi-valued data corresponding to a first colored ink to be precedently applied to a same area of the print medium, and second multi-valued data corresponding to a second colored ink to be applied to the print medium succeedingly to the first colored ink; and a quantization unit configured to convert the first multi-valued data to first quantized data designating printing or non-printing of dot using the first colored ink, and converts the second multi-valued data to second quantized data designating printing or non-printing of dot using the second colored data. The quantization unit quantizes the first multi-valued data and the second multi-valued data so as to, on the print medium, make dispersibility of dots to be printed based on the first quantized data higher than dispersibility of dots to be printed based on the second quantized data.
