Method and device for feeding printing ink into ink fountains of printing machines

摘要

The invention relates to a method for supplying printing ink in ink fountains of printing presses, in which the printing press for ink supply has an ink fountain which is assigned an ink fountain pen interacting with ink metering elements. DOLLAR A The object of the invention is to develop a method and a device by means of which a zonal metering corresponding to the color requirement takes place and the ink fountain can be left largely empty at the end of the order or when changing orders. DOLLAR A According to the invention the object is achieved in that the point in time is determined when it is no longer necessary to supply the ink for the ink zone or ink zone group with the least ink requirement until the pre-calculated end of the job, at which time a residual dosing process with changed dosing cycles is initiated, at which the remaining Ink zones or ink zone groups continue to be supplied with ink and the ink supply of the ink zones and ink zone groups concerned is discontinued if their ink requirements are met by the pre-calculated order end.
