Inventor: FAN ZHIGANG
IPC: B42D15/10
Filed: 2003-10-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a forgery preventive pattern on documents, of which the manufacture is easy, but of which the forgery is difficult.  <P>SOLUTION: The pattern of which the cycle varies is registered on the front surface and the rear surface of a document in order to provide a forgery preventing security device. The pattern of which the cycle varies is an inverted image. The document is transparent to a degree wherein the superposition of the pattern on the rear surface of the document with the pattern on the front surface of the document can be seen through. The pattern of which the cycle varies forms a moire pattern in the case of a poor registration. Since the cycle of the pattern varies, the more pattern is formed regardless of the size and the direction of the poor registration.  <P>COPYRIGHT: (C)2004,JPO
