Abstract

PURPOSE: To make it possible to judge good colors and bad colors simply and quickly without depending on intuition, experience and the like by judging the color difference between a target color with a good-product judging region in a two-dimensional color space as a reference and the surface color of a finished printed material.
CONSTITUTION: When examples of a good-product judging region are illustrated, the hue difference is shown on the X axis and the brightness difference is shown on the Y axis on one diagram with a sample pattern as the center in the indications of the color differences. The saturation difference is shown on the X axis and the brightness difference is shown on the Y axis in the other diagram. There are these two examples. With the judging region as the reference for the target color, the color difference between the surface color of the finished printed material and the target color is judged. The result is shown on a color plane. When the result is located within the good-product judging region, it is judged that the product is good. When the result is not located in the good-product judging region, the vector on the plane wherein three attributes of the colors of the finished printed material are moved is determined. The color adjustment of ink should be considered on the basis of the vector.
