Abstract
PURPOSE:To enable to control the density of printed image efficiently, by keeping water content at a standard value through provision of a means for detecting and controlling the ratio of water to ink on an ink kneading roller or an inking roller. CONSTITUTION:In an offset printing machine of the type in which water is supplied to ink on ink kneading roller 12 for humidifying the negative and kneading ink to have required properties, distribution of water drops formed by the humidifying water on ink kneading roller 12 or inking roller 13 is detected by way of optical, electric or dielectric method, and the deviation is feedbacked to the water supply system. In the above arrangement, distribution of water drops on ink kneading roller 12 can be kept constant and the density of the printed image can be kept constant by employing, for instance, a method for varying the time period when water priming roller 16 is held in contact with ink kneading water 12.
