Abstract: A conversion curve setting system comprises an initial data storage device, a conversion curve display device, a setting device, a past data storage device and a past data display device. The initial data storage device stores the initial data. The initial data define setting conditions for amounts of supplied ink of an ink supply adjusting apparatus relative to an image area ratio. The conversion curve display device displays a conversion curve on a display device on the basis of the initial data stored by the initial data storage device. The setting device sets the setting conditions for the amounts of supplied ink of the ink supply adjusting apparatus relative to the image area ratio, through operation by an operator. The past data storage device stores past data of the setting conditions for the amounts of supplied ink of the ink supply adjusting apparatus relative to the image area ratio, which setting conditions have been set by the setting device.
