An automatic multi-process ink leveler for open-fountain printing presses includes a duct with four chambers extending over the width of the ink fountain. In the case of a split ink fountain, which is typically used in newsprint presses wherein the ink tray is split into four sections each for one page of the paper web, the automatic leveler is provided with a remote-controlled valve for each chamber associated with each of the segments. Accordingly, there are provided 4x4 valves for four colors at the bottom surface of the ink leveler. By opening the remote controlled valves for a desired color (i.e., black, cyan, magenta, yellow) in the segment, a quick color change in a split ink fountain can be obtained without cleaning the entire ink leveler. In addition, different types of ink (different tack, viscosity) can be used with the same result.
