A substrate fluorescence pattern mask for inserting information to printed documents is provided to make the printed substrate which is properly exposed to the ultra violet light source as the fluorescence mark output the obviously distinguishable pattern. A substrate fluorescence pattern mask for inserting information to printed documents includes a substrate(20), a first space color pattern and the second space color pattern. The substrate includes the optical brightening agents. The first space color pattern in printed as the image on the substrate, and consists of a first color mixture and a second color mixture on a first space pattern, and has the high restraining characteristic of the substrate fluorescence. The second space color pattern is printed as the image on the substrate by approaching to the printed first space color pattern, and consists of a third color mixture and a fourth color mixture on a second space patter, and has the low restraining characteristic o the substrate fluorescence, and has the low contrast about the first space color pattern, and make the printed substrate image which is properly exposed to the ultraviolet light source as the fluorescence output the obviously distinguishable pattern. |
