PROBLEM TO BE SOLVED: To provide a method of manufacturing a printed matter in which hiding power of a latent image is high in a printed matter in which a latent image is observed under a specific illuminant.SOLUTION: A manufacture method of a dot printed matter is that two or more of a first half tone region and a second half tone region are arranged to neighbor, and a visible image and a latent image are formed. The manufacture method of a dot printed matter is characterized in that a brightness synthesis datum comprising two or more pixels having brightness of brightness of a first image datum minus brightness of a second image datum is manufactured to eliminate a difference of brightness of a first image datum that is an original image of a visible image and brightness of a second image datum that is an original image of a latent image image, then a synthesis datum that is manufactured using a brightness synthesis datum and a second image datum after mask processing, and becomes a base of a dot printed matter is output on a substrate. |
