Anti-counterfeit printed matter, method of manufacturing the same, and recording medium storing halftone dot data creation software

An anti-counterfeit printed matter having a continuous tone, comprising:

• units arranged at a predetermined pitch in a matrix on a base material,
• each of the units including:
• either a first object or a second object is arranged in a respective along a first direction in a manner so that the first region and the second region in each of the units oppose each other;
• a fifth object and a sixth object a second direction perpendicular to the first direction in a manner so as to oppose each other;
• a third object arranged between the first region and the second region along the first direction, and in an area of the unit where the first object, the second object, the fifth object, and the sixth object are not arranged;
• and
• an imaginary horizontal line extending in the second direction,
• the imaginary horizontal line being arranged approximately 25% down from a top of the unit and passing between the first region and the second region in a position that passes through a center of the third object;
• wherein the first region and the second region of each of the units have equivalent areas, and a relationship in which one of the first and second regions has a respective object, and the other of the first and second regions does not have a respective object,
• the first object being adapted to form one of a positive image and a negative image of a first invisible image, while the second object is concurrently adapted to only form the other of the negative image and the positive image of the first invisible image,
• the fifth object and the sixth object of each of the units have a relationship in which one is an off state when the other is an on state, and have equivalent areas,
• the fifth object being adapted to form one of a positive image and a negative image of a second invisible image, while the sixth object is concurrently adapted to only from the other of the negative image and the positive image of the second invisible image, and
• the third object being adapted to form a visible image having a continuous tone.
