Abstract

A system for presetting register and color zone adjusting devices in a multi-color rotary printing machine uses digitally-driven optical scanners axially traversing the plate cylinders under control of at least one numerical computer. Machine-specific characteristics are programmed in non-volatile memory as referenced values. Data processing is not required to be conducted external to the printing machine. The system is compact and requires practically no re-adjustment or entry of desired values from the machine operator. The machine operator, however, may enter coordinates for printing areas on the printing plate in order to speed up the scanning process for determining the initial color zone preset. The scanner multi-functionally scans the printing plate for both register adjustment and for integrating the ratio of printing to non-printing area for each inking zone. The system is easily reprogrammed and the optical scanner is interchangeable with a densitometer in order to provide alternative control functions during printing, such as the regulation of inking and dampening.

Description

Die Erfindung betrifft eine Vorrichtung zum Voreinstellen an Druckmaschinen, insbesondere der Register-und Farbzoneneinstellung.The invention relates to a device for presetting on printing presses, in particular the register and ink zone setting.

Es sind hierzu die unterschiedlichsten Vorrichtungen und Verfahren bekannt geworden, die den Andruckbogen bzw. einen bedruckten Bogen ausmessen und daraus eine Voreinstellung der Farbzonenschrauben ableiten.A wide variety of devices and methods have become known for this purpose, which measure the pressure sheet or a printed sheet and derive a presetting of the ink fountain keys therefrom.

Abfühlungen über Filmvorlagen haben sich wegen zu hoher Ungenauigkeit nicht bewährt.Feelings about film templates have not proven themselves due to excessive inaccuracy.

Weiterhin sind Meßverfahren bekannt, welche mit einer großen Anzahl von Meßköpfen eine auf einem Tisch plan aufliegende Platte oder eine auf einem Zylinder aufgezogene Platte außerhalb der Maschine ausmessen und die gemessenen Flächendeckungswerte Zwischenspeichern und in einem weiteren Arbeitsgang mittels unterschiedlicher Datenträger auf den Einstellmechanismus der Farbzonenschrauben übertragen.Furthermore, measuring methods are known which measure a plate lying flat on a table or a plate mounted on a cylinder outside of the machine with a large number of measuring heads and temporarily store the measured area coverage values and in a further operation by means of different data carriers on the setting mechanism of the ink fountain key.

Diese unterschiedlichen Verfahren.weisen eine Umständlichkeit auf, die mit einer Fehleranfälligkeit der einzelnen Komponenten verbunden ist. Die damit erzielte Genauigkeit der Voreinstellung ist aus diesen Gründen nicht sehr groß.These different procedures are cumbersome, which means that the individual components are prone to errors. For this reason, the accuracy of the presetting achieved with this is not very great.

Weiterhin hat das Bedienungspersonal bei dezentralen Anlagen ein recht hohen organisatorischen Arbeitsaufwand zu leisten. Kleinste Zeitverschiebungen im Ablaufplan führen in der Druckerei meist zu hohen Warte- und damit Stillstandszeiten.Furthermore, the operating personnel in decentralized systems have to do a very high amount of organizational work. Smallest time shifts in the schedule usually lead to long waiting times and therefore downtimes in the print shop.

In der DE-OS 2 922 964 ist ein System zur Druckpressenvorbereitung und -steuerung bekannt geworden. Die Voreinstellung betrifft hierbei hauptsächlich das Farbwerk, die Farbführung, das Feucht- und Falzwerk. Aufgabe soll es sein, ein System zu schaffen mit dem automatisch die genannten mechanischen Teile einer Druckpresse voreingestellt und weiter eingeregelt werden können. Hierzu sollen unter anderen Einrichtungen vorgesehen sein, mit denen die notwendigen mechanischen Einregulierungen in Abhängigkeit von eingegebenen Daten vorbestimmt werden. Zur Voreinstellung sind Parameter wie Druckpresse, Druckerzeugnis, Druckbereich und Arbeitsablauf eingebbar.A system for printing press preparation and control has become known in DE-OS 2 922 964. The default setting mainly affects the inking unit, inking, dampening and folding unit. The task is to create a system with which the mechanical parts of a printing press mentioned can be automatically preset and further adjusted. For this purpose, other devices are to be provided with which the necessary mechanical adjustments can be predetermined depending on the data entered. For presetting, parameters such as printing press, print product, printing area and workflow can be entered.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Einrichtezeit an Druckmaschinen mit einfachen Mitteln zu verkürzen.Based on this prior art, the invention has for its object to shorten the set-up time on printing presses with simple means.

Die Lösung der gestellten Aufgabe wird bei einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch erreicht, daß ein Kontrastlesegerät eine auf einen Plattenzylinder aufgespannte Druckplatte multifunktional derart abtastet, daß mittels eines über einer Rechnereinheit und Speichereinheit geschalteten Steuersignales die Register- und Farbzonenvoreinstellung direkt innerhalb der Druckmaschine einstellbar sind.The solution of the problem is achieved according to the invention in a device of the type mentioned above in that a contrast reader scans a printing plate mounted on a plate cylinder multifunctionally in such a way that by means of a control signal connected via a computer unit and storage unit the register and ink zone presetting directly within the print machine are adjustable.

In der Druckmaschine ist parallel zu einem Plattenzylinder ein Kontrastlesegerät verfahrbar angeordnet, welches in digitaler Weise die Hell-/Dunkelpartien der Druckplatte für die Register- und Farbzonenvoreinstellung zusammen ausmessen kann.In the printing machine, a contrast reading device is arranged parallel to a plate cylinder, which can digitally measure the light / dark areas of the printing plate for the register and ink zone presetting.

Da das Kontrastlesegerät innerhalb der Druckmaschine angeordnet ist, sind die Meßwerte maschinenabhängig, dies ergibt eine extreme Zeitersparnis bei der Voreinstellung, nach dem der Drucker die Druckplatte aufgespannt hat. Eine Druckbogenerstellung und -ausmessung ist für die Voreinstellung nicht erforderlich.Since the contrast reader is arranged inside the printing machine, the measured values are machine-dependent, which results in an extreme time saving in the presetting after the printer has clamped the printing plate. A print sheet creation and measurement is not necessary for the presetting.

Die Voreinstellung geht von der Erkenntnis aus, daß eine automatische Voreinstellung ausreichend ist, die den Drucker simulierend nur über die Plattenbreite gesehen bezüglich der Flächendeckung eine ja/nein-Entscheidung fällt.The presetting is based on the knowledge that an automatic presetting is sufficient, which, simulating the printer, only makes a yes / no decision with regard to the area coverage, viewed over the plate width.

Eine technisch komplizierte, qualitative Ausmessung der Flächendeckung entfällt, trotzdem wird mit dieser Voreinstellung eine wesentliche Zeitersparnis beim Einrichten der Druckmaschine erreicht.A technically complicated, qualitative measurement of the area coverage is no longer necessary, but with this presetting, considerable time is saved when setting up the printing press.

Mit dem Kontrastlesegerät wird die Druckplatte multifunktional,-d.h. die Flächendeckung der Platte sowie die Position der Platte auf dem Plattenzylinder, ausgemessen und die Register- und Farbzoneneinstellung direkt innerhalb der Druckmaschine ausgeführt. Das Kontrastlesegerät muß nicht speziell geeicht werden, da es sich seinen optimalen Arbeitspunkt automatisch ermittelt. Die Druckplatte ist vor und während der Messung nicht eingefärbt.With the contrast reader, the printing plate is multifunctional, i.e. the area coverage of the plate and the position of the plate on the plate cylinder are measured and the register and ink zone settings are carried out directly within the printing machine. The contrast reader does not have to be special be calibrated because it automatically determines its optimal working point. The printing plate is not inked before and during the measurement.

Die Druckplatte weist kreuzförmig ausgeführte Paßmarken und Hell-/Dunkelbereiche auf.The printing plate has cross marks and light / dark areas.

Während der Messung wird zuerst die Registervoreinstellung und danach die Farbzonenvoreinstellung vorgenommen. Die Registervoreinstellung teilt sich auf in Diagonal-, Umfangs- und Seitenverstellung und wird auch in dieser Reihenfolge ausgemessen und voreingestellt.During the measurement, the register presetting is made first and then the color zone presetting. The register presetting is divided into diagonal, circumferential and side adjustment and is also measured and preset in this order.

Als Nullpunktsystem zur Ausmessung des Paßkreuzes auf der Druckplatte wird in bekannter Weise eine Meßmarke oder Triggermarke, welche auf den Druckzylinder angeordnet ist, für den Zählbeginn des Weggebers verwendet.As a zero point system for measuring the register cross on the printing plate, a measuring mark or trigger mark, which is arranged on the printing cylinder, is used in a known manner for the start of counting of the displacement sensor.

Die Anzahl der Zählschritte bis zum Paßkreuz, welches vom Kontrastlesegerät ausgemessen wird, ergibt den Istwert und damit die Lage der Druckplatte auf den Plattenzylinder.The number of counting steps up to the register cross, which is measured by the contrast reader, gives the actual value and thus the position of the printing plate on the plate cylinder.

Zwischen der Register- und Farbzonenvoreinstellung ist eine Rechnereinheit mit einem Verstärker angeordnet. Der Istwert wird über die Rechnereinheit mit dem Sollwert verglichen und das daraus resultierende Steuersignal über den Verstärker auf die Registervoreinstellung geschaltet.A computer unit with an amplifier is arranged between the register and ink zone presetting. The actual value is compared with the setpoint via the computer unit and the resulting control signal is switched to the register preset via the amplifier.

Die Voreinstellung der Druckplatte auf dem Plattenzylinder wird in der oben genannten Reihenfolge und mit der druckerüblichen Genauigkeit durchgeführt. Die Genauigkeit der Voreinstellung ist abhängig von der Meßgeschwindigkeit und dem Auflösegrat des Kontrastlesegerätes. Die Genauigkeit kann je nach Anzahl der Kontrollmessungen erhöht werden bis zum Auflösegrat des Kontrastlesegerätes bei der jeweils gewählten Meßgeschwindigkeit.The presetting of the printing plate on the plate cylinder is carried out in the above order and with the accuracy customary in the printer. The accuracy of the presetting depends on the measuring speed and the resolution rate of the contrast reader. Depending on the number of control measurements, the accuracy can be increased up to the resolution of the contrast reader at the selected measuring speed.

Die Größe der Paßmarken ist hierbei in besonders vorteilhafter Weise so gewählt, daß bei üblichen Druckgeschwindigkeiten eine optimale druckerübliche Voreinstellung erreicht wird.The size of the registration marks is chosen in a particularly advantageous manner so that an optimal printer-standard presetting is achieved at conventional printing speeds.

Nach dem die Registervoreinstellung ausgeführt ist, wird der Helligkeitsunterschied zwischen druckenden und nicht druckenden Partien auf der Druckplatte multifunktional ausgemessen um die Farbzonenvoreinstellung maschinenabhängig optimal so einzustellen, daß der Drucker diese nicht oder nur bei kundenspezifischen Wünschen nachregeln muß.After the register presetting has been carried out, the difference in brightness between printing and non-printing parts on the printing plate is measured in a multifunctional manner in order to optimally adjust the ink zone presetting, depending on the machine, so that the printer does not have to readjust it or only with customer-specific requests.

Die Kompaktheit der in der Druckmaschine integrierten Meß- und Verstelleinrichtungen führt zu einer besonders hohen Reduzierung der Einrichte- und Hilfszeiten der Druckmaschine.The compactness of the measuring and adjusting devices integrated in the printing press leads to a particularly high reduction in the set-up and auxiliary times of the printing press.

Bei gleicher Auftragsstruktur verbessert sich dadurch das Verhältnis Einrichtezeit zu Fertigungszeit wesentlich.With the same order structure, the ratio of setup time to production time improves significantly.

Das Kontrastlesegerät ist ein einfaches Druckmarkenlesegerät, welches mit einer vorgewählten Geschwindigkeit über dem Plattenzylinder traversiert.The contrast reader is a simple print mark reader that traverses over the plate cylinder at a preselected speed.

Der Plattenzylinder kann je nach Empfindlichkeit bzw. Schnelligkeit der Meßwerterfassung schrittweise oder stetig mit einer bestimmten Geschwindigkeit umlaufen.Depending on the sensitivity or speed of the measured value acquisition, the plate cylinder can rotate gradually or continuously at a certain speed.

Je nach Ausführung der Meßvorrichtung kann aber auch der Bewegungsablauf umgekehrt werden, d.h. der Plattenzylinder rotiert stetig z.B. mit der größtmöglichen Geschwindigkeit, während der Meßkopf schrittweise die einzelnen Farbzonen axial abfährt, bzw. nur kleine Traversierungen entsprechend der Farbzonenbreite vornimmt. Um dies gut miteinander verknüpfen zu können, wird hierbei die Schrittweise in überlappender Weise ausgeführt.Depending on the design of the measuring device, the movement sequence can also be reversed, i.e. the plate cylinder rotates continuously e.g. at the highest possible speed, while the measuring head gradually moves axially through the individual ink zones or only makes small traverses according to the ink zone width. In order to be able to link this well, the step-by-step is carried out in an overlapping manner.

Die Auswertung der gemessenen Kontraste geschieht bei allen genannten Kombinationen in der gleichen Weise. Hierzu wird in Umfangsrichtung eine Integration der Meßwerte bezogen auf die entsprechende Position des Farbzonenabschnittes vorgenommen. Im Rechnerprogramm ist die oben genannte Randzonenverknüpfung vorgesehen.The measured contrasts are evaluated in the same way for all of the combinations mentioned. For this purpose, the measured values are integrated in the circumferential direction in relation to the corresponding position of the ink zone section. The above-mentioned linking of the boundary zones is provided in the computer program.

Die Geschwindigkeit des Kontrastlesegerätes ist abhängig vom Druckbild der Druckplatte mittels eines Display's bereichsweise unterschiedlich vorwählbar. Hierdurch kann die Meß- und Verstellzeit wesentlich verkürzt werden. Das Kontrastlesegerät traversiert hierbei mit einer Feineinstellung in Bereichen die auszumessen sind, dagegen mit einer Grobeinstellung in Bereichen in denen keine Informationen auf der Druckplatte vorhanden sind.Depending on the print image of the printing plate, the speed of the contrast reader can be preselected differently in some areas by means of a display. As a result, the measurement and adjustment time can be significantly reduced. The contrast reader traverses with a fine adjustment in areas that are to be measured, but with a coarse adjustment in areas in which no information is on the Pressure plate are present.

Ein Winkelschrittgeber ist zwischen dem Plattenzylinder und dem Druckmarkenlesegerät angeordnet. Dieser arbeitet für alle taktgebundenen bzw. geschwindigkeitsabhängigen Funktionen der Druckmaschine wie z.B. Vorderkantenabfühlung, Druckabstellung, Greifersperrung, Hebersteuerung und Puderbestäubung. Der Winkelschrittgeber nimmt die radiale Aufrasterung des Plattenzylinders vor.An angle encoder is arranged between the plate cylinder and the print mark reader. This works for all clock-related or speed-dependent functions of the printing press, e.g. Front edge sensing, pressure cut-off, gripper lock, lift control and powder dusting. The angular step encoder performs the radial engagement of the plate cylinder.

Das Steuersignal ist ohne Datenzwischenträger direkt innerhalb der Druckmaschine auf die Farbzonenschrauben und die Registerantriebe übertragbar.The control signal can be transferred directly to the ink fountain keys and the register drives without an intermediate data carrier.

In vorteilhafter Weise wird damit bei übertragungsaufträgen zwischen unterschiedlichen Druckmaschinen ein Verwechseln der Datenzwischenträger vermieden. Die Direktheit des kompakten Systems vermindert die Meß- und Verstellzeit wesentlich. Druckplattenkorrekturen können durch einfache Wiederholungsmessung kurzfristig mit berücksichtigt werden.This advantageously prevents the data intermediate carriers from being mixed up in the case of transfer orders between different printing presses. The directness of the compact system significantly reduces the measuring and adjustment time. Printing plate corrections can be taken into account at short notice by simple repeat measurements.

Das Kontrastlesegerät ist in an sich bekannter Weise mittels eines Verfahrmechanismus, ähnlich dem Plottern, an einer Traverse parallel zum Plattenzylinder verfahrbar. Die Genauigkeit ist mit einem Seilzug und seitlich angeordneten Walzen mit Schrittmotoren für das Meßverfahren auch für Kontrollmessungen optimal gegeben. Durch einfaches ablängen der Traverse kann die Kompakteinheit in alle Druckmaschinen eingebaut werden.The contrast reader can be moved in a manner known per se by means of a traversing mechanism, similar to plotting, on a traverse parallel to the plate cylinder. The accuracy is optimally given with a cable pull and laterally arranged rollers with stepper motors for the measuring method also for control measurements. By simply cutting the crossbar to length, the compact unit can be installed in all printing machines.

Das Kontrastlesegerät ist mittels einer Bajonetthalterung auswechselbar auf der Traverse angeordnet. Die Bajonetthalterung ist elektrisch abgesichert, damit kann die Druckmaschine gar nicht anlaufen, wenn das Kontrastlesegerät noch nicht eingesetzt ist.The contrast reader is interchangeably arranged on the crossbar by means of a bayonet holder. The bayonet holder is electrically secured so that the printing press cannot start when the contrast reader has not yet been inserted.

Sind mehrere Bajonetthalterungen auf der Traverse angeordnet, so ermöglichen die Bajonetthalterungen auch das Aufsetzen mehrerer Kontrastlesegeräte auf die Traverse um die Meßzeit zusätzlich zu verkürzen zu können.If several bayonet brackets are arranged on the crossbar, the bayonet brackets also enable several contrast readers to be placed on the crossbar in order to be able to additionally shorten the measuring time.

Nach jedem einzelnen Verstellvorgang der Vorein-: stellung sind die in der Rechnereinheit, hier speziell dem Festwertspeicher, vorgesehene Speicherplätze löschbar.The memory locations provided in the computer unit, here in particular the read-only memory, can be deleted after each individual adjustment process of the presetting.

Dies ist bei der Menge von Daten eine wesentliche Forderung, um den Festwertspeicher so klein wie möglich zu halten.With the amount of data, this is an essential requirement in order to keep the read-only memory as small as possible.

Mittels eines in der Bajonetthalterung nach der gesamten Voreinstellung auswechselbaren Densitometers ist beim Fortdruck eine Überwachung bestimmter Referenzsignale für Farbe und Feuchtung durchführbar. In besonders vorteilhafter Weise können alle bekannten Verfahren in der vorhandenen Meßvorrichtung nach der Voreinstellung ohne zusätzlichen Aufwand eingesetzt werden.By means of a densitometer that can be replaced in the bayonet holder after the entire presetting, certain reference signals for color and dampening can be monitored during production. In a particularly advantageous manner, all known methods can be used in the existing measuring device after the presetting without additional effort.

Die Anlage ist damit optimal in ihrer Variabilität in Bezug auf ihre Nachrüstbarkeit.The system is therefore optimal in terms of its variability in terms of retrofitting.

Weitere Vorteile und wesentliche Merkmale der Erfindung gehen aus den Unteransprüchen und der nachfolgenden Beschreibung anhand der schematisch dargestellten Ausführungsbeispielen hervor.Further advantages and essential features of the invention emerge from the subclaims and the following description on the basis of the schematically illustrated exemplary embodiments.

In der Fig. 1 ist eine Mehrfarben-Druckmaschine 1 mit Registervoreinstellungen 2 - 2.3 und Farbzonenvoreinstellungen 3 - 3.3 dargestellt.1 shows a multicolor printing machine 1 with register presets 2 - 2.3 and ink zone presets 3 - 3.3.

Die Registervoreinstellungen 2 - 2.3 wirken jeweils an Plattenzylindern 5 - 5.3. Die Register- 2 - 2.3 und Farbzonenvoreinstellung 3 - 3.3 sind ferngesteuert und rechnergekoppelt. Die für die Fernsteuerung benötigten Stellimpulse werden mit traversierenden Kontrastlesegeräten 4 - 4.3 durch ausmessen von Paßkreuzen auf Druckplatten 6 - 6.3 erzeugt. Die Druckplatten 6 - 6.3 werden vom Drucker nur einmal auf den Plattenzylindern 5 - 5.3 befestigt. Abweichungen zwischen Soll- und Istlagen der Druckplatten 6 - 6.3 werden bei der Registervoreinstellung 2 - 2.3 über eine Rechnereinheit 7 optimiert, dies verkürzt die Verstellzeit erheblich. Ist die Lageabweichung der Druckplatten 6 - 6.3 zu groß, wird dies über ein Signal zusätzlich angezeigt und die jeweilige Druckplatte 6 - 6.3 wird vom Drucker neu justiert.The register presets 2 - 2.3 each act on plate cylinders 5 - 5.3. Registers 2 - 2.3 and color zone presets 3 - 3.3 are remotely controlled and computer-linked. The positioning pulses required for remote control are generated with traversing contrast readers 4 - 4.3 by measuring registration marks on printing plates 6 - 6.3. The printing plates 6 - 6.3 are attached to the plate cylinders 5 - 5.3 only once by the printer. Deviations between the target and actual positions of the printing plates 6 - 6.3 are optimized in the register presetting 2 - 2.3 via a computer unit 7, this considerably shortens the adjustment time. If the positional deviation of the pressure plates 6 - 6.3 is too large, this is additionally indicated by a signal and the respective pressure plate 6 - 6.3 is readjusted by the printer.

Die gesamte Meß- und Verstelleinrichtung ist kompakt in der Druckmaschine 1 angeordnet und damit an die jeweiligen speziellen Eigenschaften der Druckmaschine 1 angepaßt. Diese kompakte Ausführung ist in besonders vorteilhafter Weise in. die unterschiedlichsten Arten von Druckmaschinen einbaubar.The entire measuring and adjusting device is arranged compactly in the printing press 1 and thus adapted to the particular properties of the printing press 1. This compact design can be installed in a particularly advantageous manner in the most varied types of printing presses.

In der Fig. 2 ist der Plattenzylinder 5 innerhalb der Druckmaschine 1 dargestellt. Das Kontrastlesegerät 4 ist auf einer Traverse 12 mit einem an sich bekannten Verfahrmechanismus 11 parallel zum Plattenzylinder 5 ansteuerbar verfahrbar. Als bekannter Verfahrmechanismus 11 ist hier z.B. der Antrieb gemeint, der ähnlich denen bei Plottern mit einem Seilzug und Schrittmotor zum genauen wiederholbaren Positionieren verwendet wird. Um die Meßzeit während des Traversierens noch zu verringern,können mehrere Kontrastlesegeräte 4 auf der Traverse 12 angeordnet werden.2, the plate cylinder 5 is shown within the printing press 1. The contrast reader 4 can be driven parallel to the plate cylinder 5 on a traverse 12 with a known movement mechanism 11. As a known traversing mechanism 11, the drive is meant here, for example, which is used for plotters with a cable pull and stepper motor for exact repeatable positioning. In order to reduce the measuring time during traversing, several contrast readers 4 can be arranged on the traverse 12.

Mit dem Kontrastlesegerät 4 wird der im Bereich einer Farbzonenbreite liegende Flächendeckungsgrad auf der Druckplatte 6, d.h. das Verhältnis der registrierten Signale der druckenden Partien zu Signalen der nicht druckenden Partien mittels der Rechnereinheit 7 umgeformt und als Stellwert direkt an die zugehörige Farbzonenvoreinstellung 3 weiter geleitet.With the contrast reader 4, the area coverage on the printing plate 6, i.e. the ratio of the registered signals of the printing batches to signals of the non-printing batches is transformed by means of the computer unit 7 and passed on directly as a manipulated value to the associated color zone presetting 3.

Diese multifunktionale Abtastung erlaubt eine wesentliche Verkürzung der Voreinstellung, auf Grund der zentralen Anlage und der Komprimierung des Verstell-und Meßvorganges zu einem Arbeitsgang.This multifunctional scanning allows a substantial shortening of the presetting due to the central system and the compression of the adjustment and measuring process into one work step.

Werden nach dem Voreinstellen Druckplatten 6 korrigiert oder verändert, so können diese Korrekturen sofort mitberücksichtigt werden, ohne daß Datenzwischenträger verändert werden müssen. Weiterhin führen Verschiebungen von Aufträgen zwischen unterschiedlichen Druckmaschinen 1 zu keinen Fehlbedienungen durch falsche Datenzuordnung. Die einfache und anpassungsfähige Gesamtanordnung erkennt man in Fig. 2 besonders deutlich, da nur jeweils zu den unterschiedlichen Druckmaschinentypen die Traverse 12 paßgerecht abgelängt werden muß. Das Kontrastlesegerät 4 ist in einer Bajonetthalterung auswechselbar gehaltert,wobei diese elektrisch verriegelt ist.If printing plates 6 are corrected or changed after presetting, these corrections can be taken into account immediately, without having to change intermediate data carriers. Furthermore, shifts in orders between different printing presses 1 do not lead to incorrect operation due to incorrect data assignment. The simple and adaptable overall arrangement can be seen particularly clearly in FIG. 2, since the crossmember 12 only has to be cut to length to match the different types of printing press. The contrast reader 4 is exchangeably held in a bayonet holder, which is electrically locked.

In der Fig. 3 ist der gesamte Meß- und Steuervorgang mit der Rechnereinheit 7 schematisch dargestellt. Die Rechnereinheit 7 setzt sich zusammen aus an einem Festwertspeicher 7.1 und einem flüchtigen Speicher 7.2, sowie einer Ein- und Ausgabe. Diese ist zwischen dem Druckmarkenlesegerät 9 und einem Verstärker 8.1 angeordnet. Das Druckmarkenlesegerät 9 traversiert während der Abtastung der Druckplatte 6 stetig mit einer vorgewählten Geschwindigkeit über den Plattenzylinder 5. Für die Registereinstellung 2 gibt ein Winkelschrittgeber 14.1 Referenzzeichen für den Ausgang der Messung in beiden Richtungen für die Lageerkennung. Der Plattenzylinder 5 kann je nach Empfindlichkeit bzw. Schnelligkeit der Meßwerterfassung schrittweise oder stetig umlaufen.In Fig. 3 the entire measurement and control process with the computer unit 7 is shown schematically. The computer unit 7 is composed of a read-only memory 7.1 and a volatile memory 7.2, as well as an input and output. This is arranged between the print mark reader 9 and an amplifier 8.1. The print mark reader 9 traverses continuously over the plate cylinder 5 at a preselected speed while the printing plate 6 is being scanned. For the register setting 2, an angle stepper 14.1 gives reference signs for the output of the measurement in both directions for the position detection. The plate cylinder 5 can rotate step by step or continuously depending on the sensitivity or speed of the measured value acquisition.

Die Bewegungen können auch umgekehrt werden, d.h. der Plattenzylinder 5 rotiert stetig mit der größtmöglichen Geschwindigkeit, während das Druckmarkenlesegerät 9 schrittweise die einzelnen Farbzonen axial abfährt und die Farbzonenvoreinstellung 2 - 2.3 an der Druckmaschine 1 vornimmt. In besonders vorteilhafter Weise ist der Meßweg des Druckmarkenlesegerätes 9 etwas größer als die Zonenbreite, um die Randzonen im Bereich der Übergänge gut miteinander verknüpfen zu können. Die Auswertung der gemessenen Kontraste auf der Druckplatte 6 geschieht bei den oben genannten Kombinationen in der gleichen Weise. Es erfolgt eine Integration der Meßwerte in Umfangsrichtung bezogen auf die entsprechende Position der Farbzonenbreite in der Rechnereinheit 7. Für Werte, die hierzu abgerufen werden müssen ist an die Rechnereinheit 7 ein Festwertspeicher 7.1 angeschlossen. Von der Rechnereinheit 7 wird ein Steuersignal 8 über einenThe movements can also be reversed, i.e. the plate cylinder 5 rotates continuously at the greatest possible speed, while the print mark reader 9 gradually moves axially from the individual ink zones and carries out the ink zone presetting 2 - 2.3 on the printing press 1. In a particularly advantageous manner, the measuring path of the print mark reader 9 is somewhat larger than the zone width in order to be able to link the edge zones in the area of the transitions well. The evaluation of the measured contrasts on the printing plate 6 takes place in the same way with the combinations mentioned above. The measured values are integrated in the circumferential direction in relation to the corresponding position of the color zone width in the computer unit 7. A fixed value memory 7.1 is connected to the computer unit 7 for values that have to be called up for this purpose. A control signal 8 is sent from the computer unit 7 via a

Verstärker 8.2 auf die Register- 2 und Farbzonenvoreinstellung 3 geschaltet. Bei der Registervoreinstellung 2 tastet das Druckmarkenlesegerät 9 Paßmarken 14 ab, welche auf der Druckplatte 6 angeordnet sind. Der Winkelschrittgeber 14.1 gibt Referenzsignale für den Ausgang der Messung in beiden Richtungen direkt auf das Druckmarkenlesegerät 9. Das Steuersignal 8 wird nach dem Verstärker 8.1 auf ein Umfangs- 15, Seiten-16 und ein Diagonalregisterantrieb 17 zum Einstellen der Registervoreinstellung 2 geschaltet. All diese aufgeführten Abläufe können gleichzeitig und direkt in der Druckmaschine 1 durchgeführt werden. Es entfallen spezielle Eichvorgänge, die bei den Densitometern unabwendbar waren, da das Druckmarkenlesegerät 9 seinen optimalen Arbeitspunkt automatisch ermittelt. Für die Farbzonenvoreinstellung 3 läuft das Steuersignal 8 vom Verstärker 8.1 auf einen Farbzonenverstellantrieb 18, der auf mehrere Farbzonenschrauben 10 geschaltet ist, wobei diese an einer Duktorwalze 10.1 in einem nicht näher gezeigten Farbwerk der Druckmaschine 1 angeordnet sind.Amplifier 8.2 switched to register 2 and color zone 3. With the register preset 2, the print mark reader 9 scans registration marks 14 which are arranged on the printing plate 6. The angle stepper 14.1 gives reference signals for the output of the measurement in both directions directly to the print mark reader 9. The control signal 8 is switched after the amplifier 8.1 to a peripheral 15, side 16 and a diagonal register drive 17 for setting the register preset 2. All of these listed processes can be carried out simultaneously and directly in the printing press 1. There are no special calibration processes that were inevitable with the densitometers, since the print mark reader 9 automatically determines its optimal working point. For the ink zone presetting 3, the control signal 8 runs from the amplifier 8.1 to a ink zone adjustment drive 18 which is connected to a plurality of ink zone screws 10, these being arranged on a duct roller 10.1 in an inking unit of the printing press 1 (not shown in detail).

In der Fig. 4 sind axial unterschiedliche Bereiche entsprechend den Druckbildern auf der Druckplatte 6. Das Kontrastlesegerät 4 tastet die Feinbereiche f axial langsamer und die Grobbereiche g schneller, entlang des.Plattenzylinders 5 ab.4 there are axially different areas corresponding to the printed images on the printing plate 6. The contrast reader 4 scans the fine areas f axially slower and the coarse areas g faster along the plate cylinder 5.

Fig. 5 zeigt hierzu ein Display 21. Mit diesem Display 21 können die Koordinaten der-Fein- und Grobeinstellung in einem Zahlenfeld 22 entsprechend den oben genannten Druckbildern eingegeben werden. Beschriftete Einzeltasten fixieren zu den jeweiligen Koordinaten die Einzelbefehle. Auf einem Anzeigenfeld 23 über den Eingabe- und Ausgabewerte angezeigt.5 shows a display 21 for this purpose. With this display 21, the coordinates of the fine and coarse adjustment can be entered in a number field 22 corresponding to the above-mentioned print images. Labeled Individual keys fix the individual commands to the respective coordinates. Displayed on a display panel 23 above the input and output values.
