ANTI-COUNTERFEIT PRINTED MATTER |
摘要 |
<p>This invention relates to an anti-counterfeit printed matter, including securities such as banknotes, stock certificates, and bonds, various kinds of certificates, and important documents, which requires anti-counterfeit or anti-copy. [Solving Means] A visible image is formed by a first object group arrayed in a first direction at a predetermined pitch and a second object group arranged in the non-imaging area of the first object group. The second object group forms the negative and positive images of a first invisible image by arbitrarily arranging two kinds of objects in pairs in the on/off relationship. Addition, in the anti-counterfeit printed matter, the first object group includes object portions that are formed in at least two height levels from the surface of the printed matter so as to have a predetermined difference in height, thereby forming a second invisible image.</p> |
