Abstract: An anti-counterfeit printed matter which forms an invisible image that can be visualized clearly to prevent a visible image from impeding visibility of a visualized invisible image. A plurality of object elements are arranged at a predetermined pitch in a matrix, each object element including a first object and a second object arranged along a first direction on both sides of a boundary at a center to oppose each other, and a third object and a fourth object arranged along a second direction perpendicular to the first direction on both sides of a boundary at the center to oppose 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 form a first invisible image. The third object and/or the fourth object form a second invisible image.

Abstract: This invention relates to an anti-counterfeit printed matter such as a banknote or a passport which requires anti-counterfeit or anti-copy, a method of manufacturing the same, and a recording medium storing halftone dot data creation software.

Abstract: This invention provides an anti-counterfeit printed matter which forms an invisible image that can be visualized clearly and also 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 object and a second object which are arranged along a first direction on both sides of a boundary at a center so as to oppose each other, and a third object and a fourth object which are arranged along a second direction perpendicular to the first direction on both sides of a boundary at the center so as to oppose 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.
