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.Units are arranged at a predetermined pitch in a matrix on a base material in a first direction and a second direction perpendicular to the first direction, each unit including a first object and a second object which are arranged along the first direction on both sides of a center so as to oppose each other and a third object arranged in a region without the first object and the second object, the first object and the second object of each of the units have an on/off relationship and the same area, the first objects form one of a positive image and a negative image of a first invisible image, and the second objects form the other of the negative image and the positive image of the first invisible image, and the third objects form a visible image having a continuous tone.
