Im vorliegenden Beispiel wird an den Positionen 8.2; 8.3; 8.5; 8.6 und 8.9 mehr Farbe zudosiert (Fig. 3, 4) als bei den übrigen Positionen der Farbdosierelemente 8. Vor Ende des Druckauftrages oder vor einem bevorstehenden Farbwechsel wird die Farbzufuhr aus der Farbspendereinrichtung 13 in den Pufferspeicher 9 gestoppt, wobei die restlichen, noch zu verarbeitenden Bogen noch bedruckt werden, so daß der im Pufferspeicher 9 verbliebene minimale Farbvorrat bei Ende des Druckauftrages annähernd aufgebraucht ist. Der Vorwahlzähler 11 ist auf die zu verarbeitende Bedruckstoffmenge einstellbar z.B. nach den Kriterien der Zeit oder der Bogenanzahl. Ein Steuersignal vor Druckende oder vor einer Druckunterbrechung (z.B. Farbwechsel) bewirkt die Beendigung der Farbzufuhr aus der Farbspendereinrichtung 13. The mode of operation is as follows: In the ink fountain 5 from the Color dispenser 13 under pressure offset printing ink in the Buffer memory 9 fed until there is a minimal supply of color forms. According to the color consumption is in the buffer memory 9 again added color from the ink dispenser 13. To the ink donor device 13 becomes parallel to the ink fountain roller 7 to the required, assigned to the ink metering elements 8, Position driven. In the present example, at the positions 8.2; 8.3; 8.5; 8.6 and 8.9 more color added (Fig. 3, 4) than in the remaining positions of the color metering elements 8. Before the end of Print job or before an upcoming color change Ink supply from the ink dispenser 13 into the buffer memory 9 stopped, with the remaining sheets still to be processed are printed so that the minimum remaining in the buffer memory 9 The ink supply is almost used up at the end of the print job is. The preselection counter 11 is based on the amount of substrate to be processed adjustable e.g. according to the criteria of time or number of sheets. A control signal before the end of printing or before a print interruption (e.g. color change) causes the ink supply from the Color donor device 13.
