Provided are a printing medium that is capable of expressing vivid colors without increasing the number of colors and capable of suppressing a printing cost of a dot pattern printing, and an information processing method and an information processing device that use the printing medium. According to those, it is possible to perform superposed printing of a graphic and a dot pattern with one color without using inks having different frequency characteristics, which has been conventionally considered to be impossible. On the printing medium, a dot pattern in which grid dots are arranged in accordance with a predetermined rule for defining information and a letter, a drawing pattern, a photograph and the like printed with halftone dots are superimposed and printed. The printing medium is printed in a way in which dots on the printing medium are detected from brightness information recorded in bitmap image data by a predetermined method and the dots are determined either as the grid dots that constitute the dot pattern or the halftone dots by an image analysis processing unit. |
