To provide a method and device for determining measuring and controlling points, which easily control the amount of feed water, taking into account the face that it is difficult to control the amount of feed water by determining a measuring point depending only on press plate information.
In the control method, the amount of water contained in ink on an ink roller 3 is measured to obtain a distribution of amount of water in the width direction of the roller, and then a point showing the lowest amount of water in the distribution of amount of water is taken up as a measuring and controlling point, so that the amount of feed water is controlled by referring to amounts of water at the measuring and controlling point. The device includes a measuring means to obtain the distribution of amount of water and a control means to measure and control points by detecting a point which shows the lowest amount of water in the distribution of amount of water in the direction of the roller 3.
