PROBLEM TO BE SOLVED: To provide a method of determining the lattice points of representative colors for preparing corresponding relation defining data which hardly causes a tone jump in the entire color space, an image processor, an image processing method and an image processing program. SOLUTION: The method is characterized by defining an ink quantity lattice point smoothness evaluating function for evaluating the layout smoothness of ink quantity lattice points composed of color ink quantities, and a CMY (cyan, magenta and yellow) lattice point smoothness evaluating function for evaluating the layout smoothness of CMY lattice points defined by CMY color components, and taking those CMY lattice points and the ink quantity lattice points which separately minimize the ink quantity lattice point smoothness evaluating function and the CMY lattice point smoothness evaluating function, as corresponding relation defining data preparing lattice points.
