The first printed image includes a first printed region showing a graded first hue and a second printed region showing a graded second hue, formed in such a manner that a pale part of the first printed region and a dark part of the second printed region are located at the same position and a dark part of the first printed region and a pale part of the second printed region are located at the same position. The second printed image is formed by using a light-transmitting multiple interference color shift ink having two hues, that is, a third hue in a similar color of the first hue and a fourth hue in a similar color of the second hue. |
