In recent years, the concept of universal design has been spreading in Japan. To provide easy-to-read printed material to a person, we focused on the visual feature of the person. We have verified the readability of the text for several combinations of text and background colors through a performance-based reading test.

By using the function, we have developed a color support tool for analyzing the combinations of the character and background colors contained in the printed matter.
