[0144] according to Figure 1 to Figure 3 A test piece (hereinafter called "Test piece (1)").
[0145] Specifically, first, on one surface of a rectangular flat glass plate, a coating solution of a color marking forming material made of gold colloid is applied linearly in a manner extending in the short side direction of the glass plate, Thus, two gold colloid coating films were formed. Then, on the entire surface of the glass plate with two gold colloid coatings, the exposed surface of one surface of the glass plate (the area where the gold colloid coating is not formed) and the surface of the two gold colloid coatings In the way of covering, a covering film of white pigment ink is formed by screen printing. In this way, a test piece is obtained in which the color marking 14 composed of strip-shaped layers (15, 16) and the reference region formed by the cladding layer 18 are formed on the lower surface of the translucent substrate (11) made of glass. (1), the color mark 1...
