PROBLEM TO BE SOLVED: To output an image with a high quality comprehensively by restraining local actualization of grains in the image as much as possible. SOLUTION: In a reflection type or transmission type image output device for printing an image with inks of the same color with a plurality of concentrations of n>=3, with respect to the brightness of an ink image to be reproduced on a recording medium, each brightness is set such that with the lowest brightness to be achieved by each different ink image without using an ink with a concentration lower than itself defined to be L1, L2,., Li,., Ln by the descending order, and when the brightness of the recording medium is L0, Li-1-Li<Li-Li+1 (I=1, N-1) is satisfied. |
