Description
Die Erfindung betrifft ein Verfahren zur Regelung von drucktechnischen Prozessen nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for the regulation of printing processes according to the preamble of
Die Regelung drucktechnischer Prozesse, wie z. B. eine Schnittregisterregelung, eine Farbregisterregelung oder eine Farbdichtregelung, erfolgt üblicherweise unter Verwendung von auf das Druckprodukt gedruckten Druckkontrollmarken, die mit Hilfe von Sensoren vermessen werden, wobei hierbei ermittelte Istwerte der Druckkontrollmarken mit Sollwerten für die Druckkontrollmarken verglichen werden, um auf Basis dieses Vergleichs Stellsignale für den zu regelnden drucktechnischen Prozess zu ermitteln. Derartige Druckkontrollmarken, die außerhalb des eigentlichen Druckbilds bzw. Sujets auf das Druckprodukt gedruckt werden, sind insbesondere im Zeitungsdruck störend, da im Zeitungsdruck kein Beschnitt des Druckprodukts erfolgt und demnach die Druckkontrollmarken im Endprodukt sichtbar sind. Daher besteht ein Bedürfnis nach Regelungsverfahren für drucktechnische Prozesse, die ohne derartige Druckkontrollmarken und demnach markenlos arbeiten.The regulation of printing processes, such. Example, a cut register control, a color register control or a color density control, usually using printed on the printed product pressure control marks, which are measured by means of sensors, in this case determined actual values of the pressure control marks are compared with set values for the pressure control marks to control signals based on this comparison for the printing process to be controlled. Such print control marks, which are printed on the printed product outside of the actual print image or subject matter, are particularly disturbing in newspaper printing, since there is no trimming of the printed product in the newspaper print and, accordingly, the print control marks are visible in the end product. Therefore, there is a need for control methods for printing processes that operate without such pressure control marks and therefore markless.

Die
Bei der markenlosen Regelung von drucktechnischen Prozessen unter Verwendung druckvorstufebasierter Sollwerte müssen abhängig von der Auflösung der Druckvorstufedaten große Datenmengen verarbeitet werden. Hierunter leidet die Effizienz der Regelverfahren. Werden Druckvorstufedaten mit einer geringeren Auflösung verwendet, so leidet hierunter die erzielbare Regelgenauigkeit.In the markless control of printing processes using prepress-based setpoints, large amounts of data must be processed depending on the resolution of the prepress data. This suffers the efficiency of the regulatory process. If pre-press data with a lower resolution is used, the achievable control precision suffers hereunder.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein neuartiges Verfahren zur Regelung von drucktechnischen Prozessen zu schaffen.On this basis, the present invention has the object to provide a novel method for the regulation of printing processes.
Diese Aufgabe wird durch ein Verfahren zur Regelung von drucktechnischen Prozessen gemäß Anspruch 1 gelöst. Erfindungsgemäß wird der oder jeder druckvorstufebasierte Sollwert aus Druckvorstufedaten sowie unter Berücksichtigung von Daten über die Charakteristik des Sensors, mit dessen Istwert der Sollwert verglichen wird, ermittelt.This object is achieved by a method for controlling printing processes according to
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, druckvorstufebasierte Sollwerte für drucktechnische Prozesse unter Berücksichtigung der Charakteristik des zur Vermessung des Druckbilds verwendeten Sensors zu ermitteln. Erfindungsgemäß werden bei der Regelung von Sensoren ermittelte Istwerte mit Sollwerten verglichen, die an die Charakteristik der verwendeten Sensoren angepasst sind. Es werden demnach nur solche Daten der Druckvorstufedaten zur Ermittlung der druckvorstufebasierten Sollwerte verwendet, die im Betrieb von den Sensoren im Druckbild ermittelbar sind. Hierdurch kann die handzuhabende Datenmenge deutlich reduziert werden, ohne dass jedoch die erzielbare Regelgenauigkeit beeinträchtigt wird.For the purposes of the present invention, it is proposed to determine pressure-preset-based setpoint values for printing processes taking into account the characteristic of the sensor used to measure the printed image. According to the invention, actual values determined during the control of sensors are compared with desired values which are adapted to the characteristics of the sensors used. Accordingly, only those data of the prepress data are used to determine the pressure pre-stage-based setpoint values that can be determined by the sensors in the print image during operation. As a result, the amount of data to be handled can be significantly reduced without, however, impairing the achievable control accuracy.
Vorzugsweise wird der oder jeder druckvorstufebasierte Sollwert aus den Druckvorstufedaten, aus Daten über die Charakteristik des Sensors und aus Daten über die Charakteristik des drucktechnischen Prozesses ermittelt.Preferably, the or each pre-pressure based setpoint is determined from the prepress data, data on the characteristic of the sensor, and data on the characteristic of the printing process.
Nach einer vorteilhaften Weiterbildung der Erfindung wird ein durch Druckvorstufedaten bestimmtes Solldruckbild unter Berücksichtigung der Charakteristik des jeweiligen Sensors und der Charakteristik des drucktechnischen Prozesses in ein Zwischenbild umgewandelt, wobei auf Basis des Zwischenbilds der jeweilige Sollwert für die Regelung ermittelt wird. Als Charakteristik des jeweiligen Sensors findet dabei eine Graustufenauflösung bzw. Farbstufenauflösung und/oder eine spektrale Empfindlichkeit und/oder eine geometrische Auflösung und/oder eine Messgeschwindigkeit des Sensors Verwendung. Als Charakteristik des drucktechnischen Prozesses findet dabei eine Geschwindigkeit des drucktechnischen Prozesses Verwendung.According to an advantageous embodiment of the invention, a predetermined by Druckvorstufedaten target print image is converted taking into account the characteristics of each sensor and the characteristic of the printing process in an intermediate image, based on the intermediate image of the respective target value is determined for the control. As a characteristic of the respective sensor, a grayscale resolution or color intensity resolution and / or a spectral sensitivity and / or a geometric resolution and / or a measuring speed of the sensor are used. As a characteristic of the printing process, a speed of the printing process is used.

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf
Der Istwert 11 wird mit einem Sollwert 12 unter Bildung einer Regelabweichung 13 verglichen, wobei die Regelabweichung 13 einem Regler 14 als Eingangsgröße zugeführt wird, der auf Basis der Regelabweichung 13 und eines Reglergesetzes als Ausgangsgröße eine Stellgröße 15 generiert, die als Eingangsgröße für den zu regelnden drucktechnischen Prozess 10 dient. Bei dem zu regelnden drucktechnischen Prozess 10 kann es sich z. B. um eine Schnittregisterregelung, Farbregisterregelung oder auch Farbdichteregelung handeln.The
Im Nachfolgenden soll davon ausgegangen werden, dass das Regelverfahren markenlos arbeitet, also ohne die Verwendung von auf ein herzustellendes Druckprodukt gedruckten Druckkontrollmarken. Ein Sensor zur Vermessung des Druckprodukts und damit zur Bereitstellung des Istwerts 11 vermisst demnach unmittelbar das gedruckte Druckbild des Druckprodukts, wobei der hierbei bereitgestellte Istwert 11 mit einem druckvorstufebasierten Sollwert 12 verglichen wird.In the following, it should be assumed that the control method operates without a mark, ie without the use of print control marks printed on a printed product to be produced. Accordingly, a sensor for measuring the printed product and thus for providing the
Im Sinne der hier vorliegenden Erfindung wird nun vorgeschlagen, den druckvorstufebasierten Sollwert 12 einerseits auf Grundlage von Druckvorstufedaten 16 des zu druckenden Druckbilds und andererseits auf Basis von Daten 17 über die Charakteristik des Sensors, mit dessen Istwert der Sollwert verglichen wird, zu ermitteln. Neben den Daten über die Charakteristik des Sensors können die Daten 17 auch Daten über die Charakteristik des zu regelnden drucktechnischen Prozesses enthalten, die dann ebenfalls bei der Bereitstellung bzw. Ermittlung des Sollwerts 12 berücksichtigt werden.For the purposes of the present invention, it is now proposed to determine the pressure-bias-based
Aus den Druckvorstufedaten 16 des zu druckenden Druckbilds sowie aus den Daten 17 über die Charakteristik des Sensors sowie des zu regelnden drucktechnischen Prozesses werden Daten 18 eines Zwischenbildes erzeugt, wobei die Daten 18 des Zwischenbildes gegenüber den Druckvorstufedaten 16 des zu druckenden Druckbilds im Umfang reduziert sind und nur solche Teildaten aus den Druckvorstufedaten 16 enthalten, die vom Sensor ermittelbar bzw. detektierbar sind.
Aus diesen Daten 18 des Zwischenbilds sind für die Regelung des drucktechnischen Prozesses 10 relevante Daten 19 bestimmbar, die als Sollwert 12 für die Regelung des drucktechnischen Prozesses 10 verwendet werden können.From these
Im Sinne der hier vorliegenden Erfindung wird der Sollwert 12 zur Regelung des drucktechnischen Prozesses 10 demnach aus Druckvorstufedaten 16 des zu druckenden Druckbilds bzw. Sujets abgeleitet, und zwar unter Berücksichtigung von Daten 17 über die Charakteristik des verwendeten Sensors und gegebenenfalls über die Charakteristik des drucktechnischen Prozesses. Insofern wird der von dem Sensor bereitgestellte Istwert 11 mit einem an den Sensor angepassten Sollwert 12 verglichen, der ausschließlich solche Daten enthält, die von dem Sensor am Druckprodukt während des drucktechnischen Prozesses detektierbar sind. Hierdurch ist es möglich, die handzuhabende Datenmenge einzuschränken, ohne die erzielbare Regelqualität zu beeinträchtigen.For the purposes of the present invention, the
Als Charakteristik eines Sensors kann bei der Ermittlung eines entsprechenden Sollwerts eine Graustufenauflösung bzw. eine Farbstufenauflösung und/oder eine spektrale Empfindlichkeit und/oder eine geometrische Auflösung und/oder eine Messgeschwindigkeit des Sensors berücksichtigt werden. Die Graustufenauflösung bzw. die Farbstufenauflösung sowie die spektrale Empfindlichkeit des Sensors werden bei der Ermittlung eines entsprechenden Sollwerts dadurch berücksichtigt, dass die Druckvorstufedaten gefiltert werden. Auf Basis der geometrischen Auflösung des Sensors sowie der Messgeschwindigkeit desselben kann eine geometrische Skalierung der Druckvorstufedaten erfolgen.As a characteristic of a sensor, a gray level resolution or a color level resolution and / or a spectral sensitivity and / or a geometric resolution and / or a measurement speed of the sensor can be taken into account when determining a corresponding desired value. The greyscale resolution or the color intensity resolution as well as the spectral sensitivity of the sensor are taken into account when determining a corresponding desired value by filtering the prepress data. On the basis of the geometric resolution of the sensor and the measuring speed of the same, a geometric scaling of the prepress data can take place.
Wird als Charakteristik des drucktechnischen Prozesses die Geschwindigkeit desselben berücksichtigt, so erfolgt auch eine geometrische Skalierung der Druckvorstufedaten zur Ermittlung eines entsprechenden Sollwerts.If the speed of the same is taken into account as a characteristic of the printing process, then a geometric scaling of the prepress data for determining a corresponding desired value also takes place.
Soll im Sinne der hier vorliegenden Erfindung z. B. eine Schnittregisterregelung mit Hilfe eines als Kontrasttaster ausgeführten Sensors durchgeführt werden, so wird als Charakteristik des Kontrasttasters, bei welchem es sich um einen Hell-Dunkel-Sensor handelt, die Graustufenauflösung des Kontrasttasters, die Größe eines Lichtflecks desselben sowie die spektrale Empfindlichkeit desselben berücksichtigt. Auf Basis dieser Daten über die Charakteristik des Kontrasttasters werden dann Druckvorstufedaten des zu druckenden Druckbilds in Daten des Zwischenbilds umgewandelt. Dies erfolgt, wie bereits erwähnt, durch Filterung sowie geometrische Skalierung der Druckvorstufedaten. Kann z. B. der verwendete Sensor aufgrund seiner spektralen Empfindlichkeit einzelne Farben der Druckvorstufedaten nicht detektieren, so werden diese Spektralbereiche bei Erzeugung der Daten des Zwischenbilds ausgefiltert. Weiterhin können bestimmte Strukturelemente eines Druckbilds aus den Druckvorstufedaten herausgefiltert werden, insbesondere dann, wenn die Auflösung des Sensors geringer ist als die Auflösung der Druckvorstufedaten. Abhängig von der Messgeschwindigkeit des Sensors sowie der Geschwindigkeit des drucktechnischen Prozesses kann im Wege einer geometrischen Skalierung der Druckvorstufedaten die Datenmenge weiter reduziert werden, so dass letztendlich die Daten des Zwischenbilds, aus welchen der entsprechende Sollwert ermittelt wird, an die Empfangscharakteristik des verwendeten Sensors angepasst sind.Should be in the sense of the present invention z. B. a cut register control using a designed as a contrast sensor sensor are performed, as the characteristic of the contrast sensor, which is a light-dark sensor, the grayscale resolution of the contrast sensor, the size of a light spot thereof and the spectral sensitivity of the same considered , On the basis of this data on the characteristics of the contrast scanner, prepress data of the print image to be printed is then converted into data of the intermediate image. This is done, as already mentioned, by filtering as well as geometric scaling of the prepress data. Can z. If, for example, the sensor used does not detect individual colors of the prepress data due to its spectral sensitivity, then these spectral regions are filtered out when the data of the intermediate image is generated. Furthermore, certain structural elements of a printed image can be filtered out of the prepress data, in particular if the resolution of the sensor is lower than the resolution of the prepress data. Depending on the measuring speed of the sensor and the speed of the printing process, the amount of data can be further reduced by way of geometric scaling of the prepress data, so that ultimately the data of the intermediate image from which the corresponding desired value is determined are adapted to the reception characteristic of the sensor used ,
Das erfindungsgemäße Verfahren kann bei allen drucktechnischen Prozessen Verwendung finden, die ohne Verwendung von in ein Druckprodukt zu druckenden Druckkontrollmarken und demnach markenlos geregelt werden sollen. Dabei können die Druckvorstufedaten auf Basis der Charakteristik der entsprechend verwendeten Sensoren angepasst werden. Bei den Sensoren kann es sich z.B. um Kontrasttaster, um CCD-Zeilenkameras bzw. CCD-Flächenkameras, um CMOS-Zeilenkameras bzw. CMOS-Flächenkameras oder auch um faseroptische Sensoren handeln.The method according to the invention can be used in all printing technology processes which are to be controlled without the use of print control marks to be printed in a printed product and therefore without a mark. In this case, the prepress data can be adjusted based on the characteristics of the sensors used accordingly. The sensors can be, for example, contrast scanners, CCD line scan cameras or CCD area cameras, CMOS line scan cameras or CMOS area scan cameras or even fiber optic sensors.
