Abstract
A method for presetting an ink feed in multi-color printing derives presetting values for zonal ink metering devices and for ink metering rollers acting over a printing width from a set value for a weight per unit area of a full tone area, zonal area coverage values and an ink stripe width. For each of a plurality of printing inks, the zonal ink metering devices and the ink metering rollers are preset in dependence of an ink demand for an image to be printed.
