The present invention relates to an ink feeding device for a digital printing machine. The ink feeding device includes: ink containers which store inks in colors different from each other; ink supplying hoses which are individually connected to each ink container and are directly connected to each of multiple head units; and an ink control valve which is arranged on the ink supplying hose and controls supply of the ink from the ink container to the head unit. Unlike the prior technology, the inks in colors different from each other are individually supplied to each of the head units corresponding to the ink. Therefore, defection of printing caused by mixed inks can be prevented. |
