摘要:
An anti-counterfeit printed matter forming an invisible image that can be visualized clearly and prevents a visible image from impeding visibility of a visualized invisible image. In the anti-counterfeit printed matter according to this invention, a plurality of object elements are arranged at a predetermined pitch in a matrix, each object element including a first and second object arranged along a first direction on both sides of a boundary at a center, opposing each other, and third and fourth objects arranged along a second direction perpendicular to the first direction on both sides of a boundary at the center, opposing each other. The first object and the second object, and the third object and the fourth object of each object element have a negative/positive relationship. The first object and/or the second object forms a first invisible image. The third object and/or the fourth object forms a second invisible image.
