Description

Die hierbei mit Diagramm bezeichnete Aus ='=rtung wird dem jeweiligen Farbwerk übergeben. Durch. mechanische oder elektrische Anzeige auf einer vertikal aufgeteilten Fläche oder Skala wird die ermittelte Zonenschrauben-Stellung entsprechend vorgenommen. Diese kann durch Stellmotoren mit Vorwähler oder durch manuelle Verstellung über Kontaktstrom (Lochkarte) während der Vorbereitung zum Drucken erfolgen. Der Bedruckstoff (Papier) erhält zonenweise die entsprechende Farbmenge, die sich durch die voraus ermittelte Zonenschrauben-Stellung ergeben wür-le. Die bisherige manuelle Einstellung der Zonenschrauben ist bei einwandfreien Reproduktionen kaum nennenswert.The outlook marked with a diagram is given to the respective Inking unit handed over. By. mechanical or electrical display on a vertical The determined zone screw position is corresponding to the divided area or scale performed. This can be done by servomotors with preselector or by manual adjustment via contact current (punch card) during preparation for printing. Of the The printing material (paper) receives the appropriate amount of ink in zones, which is reflected through the previously determined zone screw position results in Wür-le. The previous manual Adjustment of the zone screws is hardly worth mentioning in flawless reproductions.

Zusammenfassung /lt Dies ist das Verfahren für den Offsetdruck, das dadurch gekennzeichnet ist, daß mit einer Vorrichtung zum Messen der integralen Dichtevertelung von der transparenten Kopiervorlage (Film-Montage) eine Übertragung dieser Troerte entsprechend Farbverbrauch auf die Zonenschrauben-Stellung der Druck durchgeführt wird.Summary / lt This is the procedure for offset printing that characterized in that having a device for measuring the integral Density distribution from the transparent master copy (film montage) a transfer this troerte corresponds to ink consumption on the zone screw position of the pressure is carried out.

Betr. : PATENTANMELDUNG Anspruch.. Vorberechnete Zonenschrauben-Stellung im Offsetdruck Die Einstellung des Farbmessers am Farbkasten einer Druckmaschine läßt sich mit Hilfe der Zonenschrauben entsprechend der Zusammensetzung der Druckform_regulieren. (ohne Zonenschrauben-Regulierung würde die Farbe auf den Auftragswalzen unterschiedlich gespeichert:) Eine vorberechnete Zonenschrauben-Stellung, dadurch gekennzeichnet, daß die manuelle Verstellung der Zonenschrauben durch Einzel-Auswertung der Druckformen (Film-Montage im Offset) und Übertragung auf die Zonenschrauben-Stellung weitgehenst entfällt, läßt den Anteil der Einlaufbogen wesentlich reduzieren. Die Verteilung, d. h. von Druckanfang bis Druckende sich ergebenen integralen Anteile von Flächen; Raster und Strichen (Schriften) werden zonenweise lichtelektrisch ausgewertet. Dieses erfolgt durch Abtastung der jeweiligen Maschinen-Montage (Transparent) auf einer Leuchtfläche mit Fotozellen. Das mit Rechenwerk ermittelte Diagramm - Lochkarte oder Vorwähler - der integralen Verteilung von druckenden Elementen gibt die Null-Abweichungen der Zonenschrauben-Stellung-je nach, entsprechendem Farbverbrauch der Druckplatte an. (Druckform-schematisch) Beispiel: Zonenschrauben-Stellung I. ohne Druck = II. Druck wie Abb. A = 3 III. Druck wie Abb. B variabel
Re. : PATENT APPLICATION Claim .. Pre-calculated zone screw position in offset printing The setting of the ink knife on the ink fountain of a printing machine can be regulated with the help of the zone screws according to the composition of the printing form. (Without zone screw regulation, the color would be stored differently on the application rollers :) A precalculated zone screw position, characterized in that the manual adjustment of the zone screws by individual evaluation of the printing forms (film assembly in offset) and transfer to the zone screw position largely omitted, allows the proportion of inlet bends to be reduced significantly. The distribution, ie from the start of printing to the end of printing, the integral proportions of areas; Raster and dashes (fonts) are zonally evaluated photoelectrically. This is done by scanning the respective machine assembly (transparent) on a luminous surface with photo cells. The diagram - punch card or preselection - of the integral distribution of printing elements determined with an arithmetic unit indicates the zero deviations of the zone screw position depending on the corresponding ink consumption of the printing plate. (Schematic of printing form) Example: Zone screw position I. without pressure = II. Print as Fig. A = 3 III. Pressure like Fig. B variable
