Abstract (en)

An ink cartridge (1) fits to an ink ductor (2) stretching across the whole width of the ink cartridge. An ink gauger (3) divided into several sections (3.1-3.x) fits on the ink cartridge's side facing the ink ductor. The ink gauger's sections make up ink zones fitted with ink dosing elements that place the ink gauge's relevant section at a defined distance from the ink ductor according to ink need in the corresponding ink zones, so that a dosing gap is formed between the ink ductor and the ink gauge along the length of the ink ductor.

Abstract (de)

Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Zuführen von Druckfarbe in Farbkästen (1) von Druckmaschinen., bei dem der Farbbedarf der Farbzonen ermittelt, diese Werte einem Rechner zugeführt werden, dort verarbeitet werden und Steuerbefehle zur zonalen, dem lokalen Farbbedarf entsprechenden Versorgung der einzelnen Farbzonen ausgegeben werden. Aufgabe der Erfindung ist es, ein Verfahren und eine Einrichtung zu entwickeln, durch die eine dem Farbbedarf entsprechende zonale Dosierung erfolgen kann, wobei die im Farbkasten (1) befindliche Farbe mit der neu zudosierten Farbe intensiv vermischt werden soll. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die zonale Versorgung der Farbzonen in Versorgungszyklen erfolgt, wobei die erforderliche Farbmenge für die Versorgung der Farbzonen an einer ortsfesten Versorgungsstelle eingebracht wird, ausgehend von dieser Versorgungsstelle eine Farbspachtel (11) die erforderlich Farbmenge zu der versorgungsbedürftigen Farbzone schiebt. <IMAGE>
