<p>PROBLEM TO BE SOLVED: To provide an anti-copying sheet, which utilizes the difference between the glosses of coloring materials so as to allow to easily judge the authenticity of a sheet by viewing at its site neither a special printing such as a super- precision printing or the like is required nor instruments such as magnifying glasses, black lights or the like are employed. SOLUTION: In this anti-copying sheet 1, an authenticity judging part 3 is formed on the surface of a base material 2. Further, the authenticity judging part 3 consists of a ground made of a lowly reflective dark-color based ink printing part 4 and an over-print varnish printing part 5 applied on the part 4.</p> |
