HIDDEN IMAGE GAME PIECE

摘要

A hidden image game piece (1) and a method by which a hidden image game piece is produced. A first pattern of colored ink (30) is deposited on a transparent or highly translucent substrate at 110180 density, forming the image which is to be hidden. Then a second pattern of colored ink (20), of a different color than the first pattern's ink, is deposited upon the substrate on top of the first pattern, at 90170 density. When the game piece is flooded with additive light of the same color as the second pattern's ink, the previously concealed image, composed of the pattern's ink, becomes perceptible. Because a transparent of highly translucent substrate is used for the game piece, and because the density of the ink application is controlled within specific ranges, this game piece is used with a computer monitor, or with other low-intensity sources of additive light.
