IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

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.

1. An image processing apparatus, comprising:
a quantization unit configured to quantize multi-valued data corresponding to a first ink which is pigment ink to generate first quantized data using a threshold value in a threshold value matrix in which multiple threshold values are arrayed, and quantize multi-valued data corresponding to a second ink which is dye ink to generate a second quantized data using a threshold value in a threshold value matrix in which multiple threshold values are arrayed; and an outputting unit configured to output data, based on the first quantized data and the second quantized data, used for printing by a printing unit which prints an image on a print medium by dots of the first ink and dots of the second ink, wherein, in a case where the multi-valued data corresponding to the first ink indicates intermediate density and the multi-valued data corresponding to the second ink indicates intermediate density, a first dot pattern determined in accordance with the first quantized data has higher dispersibility than a second dot pattern determined in accordance with the second quantized data.
