PROBLEM TO BE SOLVED: To propose a fabrication prevention document in which a fabrication prevention effect may be improved.SOLUTION: There is provided a fabrication prevention document 1 in which a background image 11 printed on a sheet face comprises continuous line patterns 12, 13, formed by drawing plural non-closed pattern elements in which straight lines and/or curves are continuous with regulation, in a single stroke of the brush. According to the fabrication prevention document 1, even when the continuous line patterns 12, 13 on the background image 11 are viewed for fabrication and the like, structures of the continuous line patterns 12, 13 are hardly recognized accurately, so that a fabrication prevention effect is improved.SELECTED DRAWING: Figure 1 |
