PROBLEM TO BE SOLVED: To provide thread-containing print paper which prevents forgery and can be formed at a low cost, and to provide a printed product using the same. SOLUTION: In the thread-containing print paper produced by adding threads at a step for making base paper for the prevention of forgery, the threads are formed between the front side paper layer and the back side paper layer of the base paper, and in the front and back side paper layers, unit openings having a size for exposing all the threads in a width direction are formed at thread-formed positions at a prescribed interval, and the unit openings formed on the front and back sides are arranged so that the unit openings are partially overlapped in a prescribed cycle. A printed product uses the thread-containing print paper in which the threads are formed along the shorter side of the printed product. COPYRIGHT: (C)2008,JPO&INPIT |
