Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Druckmaschine, insbesondere einer Offset-Druckmaschine, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a printing machine, in particular an offset printing press, according to the preamble of claim 1.
In Bogendruckmaschinen wird ein bogenförmiger Bedruckstoff, in Form so genannter Druckbogen, durch mehrere Druckwerke bewegt, um auf den bogenförmigen Bedruckstoff ein Druckbild aufzutragen. Zum Drucken finden in den Druckwerken Druckformen, typischerweise Druckplatten, Verwendung, die unter Berücksichtigung von druckvorstufebasierten Bilddaten sowie unter Berücksichtigung von Bedruckstoffdaten hergestellt werden. So hat nämlich der verwendete Bedruckstoff Auswirkungen auf das beim Drucken erzeugte Druckbild, weshalb Daten über den Bedruckstoff bereits bei der Druckformherstellung bzw. in der Druckvorstufe berücksichtigt werden. Im Offsetdruck erfolgt die Einteilung der Bedruckstofftypen nach bestimmten Eigenschaften, nämlich nach der Farbe von unbedruckten Abschnitten des Bedruckstoffs, nach dem Glanz von unbedruckten Abschnitten des Bedruckstoffs, nach der Tonwertzunahme bzw. den Druckkennlinien der Druckfarben beim Bedrucken, nach dem im Druck wiedergebbaren Farbumfang, sowie nach dem Durchscheinen eines beim Drucken auf den Bedruckstoff aufgetragenen Druckbilds. Der Farbumfang, der im Druck wiedergegeben werden kann, wird auch als Gamut und das Durchscheinen wird auch als Opazität bezeichnet.In sheet-fed presses, a sheet-shaped printing material, in the form of so-called printing sheet, is moved through a plurality of printing units in order to apply a printed image to the sheet-shaped printing material. For printing, the printing units use printing plates, typically printing plates, which are produced with consideration of prepress-based image data and taking into account substrate data. This is because the printing substrate used has an effect on the printed image produced during printing, which is why data about the printing substrate are already taken into account during the printing plate production or in the prepress stage. In offset printing, the classification of the types of printing material according to certain properties, namely the color of unprinted sections of the substrate, after the gloss of unprinted sections of the substrate, after the dot gain or the printing characteristics of the printing inks when printing, after the reproduced in the color gamut, and after showing a printed image on the substrate during printing. The color gamut that can be reproduced in print is also called gamut, and show through is also called opacity.
Wird beim tatsächlichen Bedrucken des Bedruckstoffs in der Druckmaschine ein Bedruckstoff verwendet, der von dem Bedruckstoff, auf Grundlage dessen Eigenschaften bzw. Daten die Druckformen hergestellt sind, abweicht, so kann sich die Färbung im Druck soweit verschieben, dass Makulatur gedruckt wird. Unter Umständen ist die komplette Druckauflage unbrauchbar und muss vernichtet werden. Dies verursacht hohe Kosten. Bislang sind keine Verfahren zum Betreiben einer Druckmaschine bekannt, die diesem Problem Rechnung tragen.If the actual printing of the printing substrate in the printing press uses a printing material that is different from the printing substrate on the basis of which the printing plates are made, the coloration in the print may shift to the point where waste is printed. Under certain circumstances, the complete print run is unusable and must be destroyed. This causes high costs. So far, there are no procedures to operate a printing machine, which take this problem into account.

Bedruckstoffdaten demjenigen Bedruckstoff entspricht, auf Grundlage dessen die zum Drucken verwendeten Druckformen hergestellt sind.According to the invention, at least one unprinted and / or at least one printed portion of the printing material is measured, wherein at least one determined actual value is compared with at least one printing material-dependent setpoint value in order to determine on the basis of the comparison whether the printing material actually used corresponds to that printing material with regard to its properties or printing material data on the basis of which the printing plates used for printing are made.
Mit dem erfindungsgemäßen Verfahren wird erstmals vorgeschlagen, mindestens einen unbedruckten und/oder mindestens einen bedruckten Abschnitt eines Bedruckstoffs zu vermessen, und hierbei Istwerte zu ermitteln, die mit bedruckstoffabhängigen Sollwerten verglichen werden. Auf Basis des Vergleichs kann festgestellt werden, ob der tatsächlich zum Drucken verwendete Bedruckstoff dem Bedruckstoff entspricht, auf Basis dessen Eigenschaften in der Druckvorstufe Druckformen hergestellt worden sind. Gegebenenfalls kann auf Basis dieses Vergleichs ein Druckprozess abgebrochen werden, um das Drucken von Makulatur zu vermeiden.With the method according to the invention, it is proposed for the first time to measure at least one unprinted and / or at least one printed section of a printing material, and in this case to determine actual values which coincide with substrate-dependent setpoint values are compared. Based on the comparison, it can be determined whether the substrate actually used for printing corresponds to the substrate on the basis of which properties in the prepress stage printing plates have been produced.

Bei den Druckformen handelt es sich üblicherweise um Druckplatten und bei den Übertragungsformen um Gummitücher, weshalb die Formzylinder 14 auch als Plattenzylinder und die Übertragungszylinder 15 auch als Gummizylinder bezeichnet werden.Of the
Die auf den Formzylindern 14 positionierten Druckformen, die zum Drucken verwendet werden, werden in einer sogenannten Druckvorstufe auf Basis von Druckbilddaten sowie auf Basis von Daten bzw. Eigenschaften des zu bedruckenden Bedruckstoffs hergestellt. Bei den Daten bzw. Eigenschaften des Bedruckstoffs, die bei der Druckformherstellung berücksichtigt werden sollen, handelt es sich insbesondere um
- die Farbe von unbedruckten Abschnitten des Bedruckstoffs,
- den Glanz von unbedruckten Abschnitten des Bedruckstoffs,
- die Tonwertzunahmen bzw. die Druckkennlinien der Druckfarben beim Drucken,
- den wiedergebbaren Farbumfang beim Drucken, den so genannten Gamut, und
- das Durchscheinen eines Druckbilds durch den Bedruckstoff, die so genannte Opazität.
- the color of unprinted sections of the substrate,
- the gloss of unprinted sections of the substrate,
- the tonal value increases or the printing characteristics of the printing inks during printing,
- the reproducible color gamut when printing, the so-called gamut, and
- the transparency of a printed image through the substrate, the so-called opacity.
Im Sinne der hier vorliegenden Erfindung werden mindestens ein unbedruckter Abschnitt und/oder mindestens ein bedruckter Abschnitt des Bedruckstoffs vermessen, wobei hierbei mindestens ein ermittelter Istwert mit mindestens einem bedruckstoffabhängigen Sollwert verglichen wird. Auf Basis des Vergleichs wird festgestellt, ob der tatsächlich zum Bedrucken verwendete Bedruckstoff hinsichtlich seiner Eigenschaften bzw. Bedruckstoffdaten demjenigen Bedruckstoff entspricht, auf Grundlage dessen in der Druckvorstufe die zum Drucken verwendeten Druckformen hergestellt worden sind.For the purposes of the present invention, at least one unprinted section and / or at least one printed section of the printing material are measured, in which case at least one determined actual value is compared with at least one printing material-dependent setpoint value. On the basis of the comparison, it is determined whether the substrate actually used for printing corresponds in terms of its properties or substrate data to the substrate on the basis of which the printing plates used for printing were produced in the prepress.
Für den Fall, dass festgestellt wird, dass der tatsächlich verwendet Bedruckstoff von demjenigen Bedruckstoff, auf Grundlage dessen die zum Drucken verwendeten Druckformen hergestellt worden sind, abweicht, wird automatisch eine Fehlermeldung bzw. Warnmeldung generiert und signalisiert. Bei großen Abweichungen in der Charakteristik zwischen dem tatsächlich verwendeten Bedruckstoff und dem in der Druckvorstufe angenommenen Bedruckstoff wird gegebenenfalls die Druckmaschine angehalten bzw. das Drucken der Auflage unterbrochen. Bei relativ kleinen Abweichungen hingegen kann durch Beeinflussung von Druckparametern eine Regelung erfolgen, um die so bedingten Farbabweichungen zu minimieren.In the event that it is determined that the substrate actually used differs from the substrate on the basis of which the printing plates used for printing have been deviated, an error message or warning message is automatically generated and signaled. For large deviations in the characteristic between the actual substrate used and the presupposed in the prepress substrate if necessary, the printing press is stopped or interrupted the printing of the support. By contrast, with relatively small deviations, regulation can be effected by influencing pressure parameters in order to minimize the color deviations thus caused.
Dann, wenn mindestens ein unbedruckter Abschnitt des Bedruckstoffs vermessen wird, erfolgt die Vermessung des oder jeden unbedruckten Abschnitts mit Hilfe einer Farbmesseinrichtung und/oder mit Hilfe einer Glanzmesseinrichtung und/oder mit Hilfe einer Opazitätsmesseinrichtung.

Vorzugsweise erfolgt das Vermessen des oder jedes unbedruckten Abschnitts sowie das Vermessen des oder jedes bedruckten Abschnitts mit Hilfe einer Farbmesseinrichtung, nämlich einer spektralen Farbmesseinrichtung, die Istwerte im sogenannten L*a*b-Farbraum ermittelt. Diese Istwerte im L*a*b-Farbraum werden mit Sollwerten im L*a*b-Farbraum verglichen, nämlich derart, dass jeder Istwert mit mehreren für unterschiedliche Bedruckstofftypen hinterlegten Sollwerten verglichen wird. Auf Basis dieses Vergleichs wird dann festgestellt, ob der tatsächlich verwendete Bedruckstoff hinsichtlich seiner Eigenschaften bzw. Bedruckstoffdaten demjenigen Bedruckstoff entspricht, auf Grundlage dessen in der Druckvorstufe Druckplatten belichtet worden sind.Preferably, the measurement of the or each unprinted portion and the measurement of the or each printed portion by means of a color measuring device, namely a spectral color measuring device, the actual values in the so-called L * a * b color space is determined. These actual values in the L * a * b color space are compared with set values in the L * a * b color space, namely such that each actual value is compared with a plurality of desired values stored for different types of substrate.

Bedruckstoffdaten demjenigen Bedruckstoff entspricht, auf Grundlage dessen in der Druckvorstufe Druckformen hergestellt worden sind.With the aid of the method according to the invention, it is possible to check inline or online for print production as to whether a printing material actually used for printing corresponds to the printing material in terms of its properties or printing material data, on the basis of which printing plates have been produced in the prepress stage.
Werden hierbei nur relativ geringe Abweichungen des Bedruckstofftyps festgestellt, so kann durch eine Regelung von Prozessparametern die sich ergebende Farbabweichung kompensiert werden. Bei relativ großen Abweichungen wird vorzugsweise der Druckprozess abgebrochen, um das Drucken von Makulatur zu vermeiden.If only relatively small deviations of the printing material type are detected, then the resulting color deviation can be compensated by regulating process parameters. For relatively large deviations, the printing process is preferably aborted in order to avoid the printing of waste.
