Die Rotationsdruckmaschine 30 ist so aufgebaut, dass bei Bedarf weitere angedeutete Heißlufttrockner 40 im Überbau 41 oberhalb der Sektionen 32; 33; 34 angeordnet werden können. Werden die Drucktürme 35 der entsprechenden Sektion 32; 33; 34 durch Drucktürme 13 ersetzt, kann auch hier eine wahlweise Produktion im Cold- oder im Heatset stattfinden.The
Wichtig ist hervorzuheben, dass die Vorrichtung zur automatischen Farbversorgung mindestens eines Druckwerks 01 einer Rotationsdruckmaschine mit Cold- und Heatset eine wesentlich flexiblere Produktion erlaubt, verbunden mit sehr kurzen Umrüstzeiten bei sich ändernder Produktion. Dies stellt im harten Preiskampf in der Druckindustrie einen wesentlichen Wettbewerbsvorteil dar.It is important to emphasize that the device for automatic ink supply at least one printing unit 01 a rotary press with cold and heatset allows a much more flexible production, combined with very short changeover times with changing production. This represents a significant competitive advantage in the tough price war in the printing industry.
Die erste Grenze am Ende einer vorgegebenen Anzahl von Druckprodukten ist geringer als eine zweite Grenze. Sie wird bei ca. 5000, insbesondere 1000 Druckprodukte vor Ende der vorgegebenen Anzahl von Druckprodukten aktiviert.The first limit at the end of a given number of printed products is less than a second limit. It is activated at about 5000, in particular 1000 printed products before the end of the predetermined number of printed products.
Eine Steuereinrichtung legt einen Ablauf eines Waschvorganges einer Wascheinrichtung für Farbwalzen fest.A controller determines a sequence of a washing operation of a washing device for inking rollers.
