ABSTRACT:
An image processing method generates a color separation table, the color separation table being used in converting an image signal to a signal for a colorant for use in a printer and storing grid-point data as the colorant signal so as to associate the grid-point data with a grid point defined by the image signal. The image processing method includes obtaining data of a first color separation table and generating a second color separation table based on the difference between a maximum allowable amount of colorant discharge for the first color separation table and a maximum allowable amount of colorant discharge for the second color separation table and the data of the first color separation table so that a total amount of colorant discharge of the second color separation table does not exceed the maximum allowable amount of colorant discharge for the second color separation table.
