A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are arranged with the original picture just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film. Thereby, the state of the area, which corresponds to the imprint figure, of the resin seal face member or the remaining part thereof is changed. Finally, an uneven face serving as a seal is formed by applying a developing fluid to this resin seal face member.
