Provided is a device that can highly precisely produce a light guide plate having a desired tint and color temperature. An inkjet printer is provided with a white ink supply unit such that an ink vessel houses white ink containing coloring pigment-based particles, the ink vessel is connected to the recording head of the inkjet printer, the recording head is caused to be able to discharge white ink, and in the white ink, the amount of contained coloring pigment-based particles, which are copper phthalocyanine, is adjusted in accordance with the desired color temperature of the light guide plate. Using white ink of which the copper phthalocyanine content has been adjusted, the inkjet printer forms a reflective print on the light guide plate, and thus a light guide plate is produced provided with a color temperature corresponding to the white ink.
