A stamp image forming method and apparatus and a stamp-making apparatus using same are provided. Previously stored relief data represents an image of a stamp of interest in the form of positive dots corresponding to protrusions and blank portions of the image in the form of negative dots corresponding to recesses. The relief data is read to generate intaglio data representing the image in the form of negative dots and the blank portions in the form of positive dots based on the relief data. In place of the relief data, relief basic data may be stored which represents an image of a stamp of interest in the form of positive dots corresponding to protrusions and blank portions of the image in the form of negative dots corresponding to recesses. The relief basic data is read, and a positive dot group comprising the positive dots in the relief basic data is extended to generate relief data representing an emphasized image, including the image formed of an extended positive dot group, in the form of positive dots and representing the remaining blank portions in the form of negative dots. Intaglio data representing the emphasized image in the form of negative dots and representing the remaining blank portions in the form of positive dots is generated based on the relief data.
