Description

Verfahren zum Durchführen von Druckaufträgen  Method for performing print jobs
Die Erfindung betrifft ein Verfahren zum Durchführen von Druckaufträgen, eine Flexodruckmaschine sowie einen Körper. Die genaue Ausgestaltung der Gegenstände der Erfindung ist den Ansprüchen 1 , 5 und 9 zu entnehmen. The invention relates to a method for performing print jobs, a flexographic printing machine and a body. The exact configuration of the objects of the invention can be found in claims 1, 5 and 9.
Zur Abwicklung von Druckaufträgen mit Mehrfarbendruckmaschinen ist es nötig, die Registerlage der Druckplattenzylinder miteinander abzugleichen. To process print jobs with multicolor printing machines, it is necessary to match the register position of the printing plate cylinders with each other.
Bei Flexodruckmaschinen - insbesondere bei Zentralzylinderflexo- druckmaschinen - wird in der Regel mit Hilfe so genannter Bahn-Bahn- Verfahren die Registereinstellung durchgeführt. Zu der Ausführung dieser Verfahren besitzen die Druckformen, mit denen die einzelnen Druckplattenzylinder gerüstet sind, Registermarkendruckformen, welche den Bedruckstoff mit Registermarken versehen. Wird mit mehreren Farbwerken gleichzeitig gedruckt, so kann die Position, die die von den einzelnen Druckwerken gedruckten Registermarken auf dem Bedruckstoff einnehmen, gemessen werden. Durch eine Korrektur der Winkellage der Druckplattenzylinder zueinander wird während der Längsregistereinstellung ein Sollabstand zwischen den Registermarken eingestellt. Bei der Einstellung des Seitenregisters wird die axiale Lage der Druckplattenzylinder zueinander solange korrigiert, bis auf dem Bedruckstoff wieder Sollabstände zwischen den Registermarken der verschiedenen Druckwerke eingehalten werden. In the case of flexographic printing presses-in particular in the case of central cylinder flexographic printing presses-register registration is generally carried out with the aid of so-called web-to-web methods. In order to carry out these methods, the printing plates with which the individual printing plate cylinders are equipped have register mark printing forms which register the printing material with register marks. If you are printing with more than one inking unit at a time, you can measure the position of the registration marks printed by the individual printing units on the substrate. By correcting the angular position of the printing plate cylinders relative to one another, a desired spacing between the register marks is set during the longitudinal register adjustment. When setting the page register, the axial position of the printing plate cylinder is corrected each other until the printing material again set distances between the register marks of the various printing units are maintained.
Der Druckschrift EP 1 916 102 A1 ist eine von der vorstehenden Norm abweichende Art des Registerns einer Flexodruckmaschine zu entnehmen: In einer externen Zylinderaufnahme, oft Reck genannt, werden verschiedene Messungen an einem mit einer Flexodruckform gerüsteten Druckplattenzylinder ausgeführt. Mit einer dieser Messungen wird die Position einer Magnetpille, die in die Druckform oder den Druckformträger eingebracht ist, bestimmt. Document EP 1 916 102 A1 discloses a type of registering a flexographic printing machine deviating from the above standard: In an external cylinder recording, often called a stretching, various measurements are made on a printing plate cylinder equipped with a flexographic printing plate executed. With one of these measurements, the position of a magnetic pill, which is introduced into the printing plate or the printing plate carrier determined.
Später werden mehrere auf diese Weise behandelte Druckplattenzylinder in jeweils ein Farbwerk der Druckmaschine eingebracht. In der Druckmaschine wird die Winkelposition der Magnetpille an dem Druckplattenzylinder gemessen, und es wird die Registerlage der Zylinder zueinander eingestellt. Later, several printing plate cylinders treated in this way are introduced into one inking unit of the printing press. In the printing machine, the angular position of the magnetic pellet is measured on the printing plate cylinder, and the register position of the cylinders is adjusted to each other.
Daher wird bei der EP 1 916 102A1 das Register zwischen den in den Farbwerken befindlichen Druckplattenzylindern aufgrund von Messsignalen eingestellt, welche die Position von Körpern betreffen, die von der Druckform oder dem Druckformträger getragen werden. Therefore, in EP 1 916 102A1, the register is set between the printing plate cylinders located in the inking units on the basis of measuring signals concerning the position of bodies carried by the printing form or the printing form carrier.
Die Körper sind die in den Druckformen befindlichen Magnetpillen. Zu den Nachteilen eines solchen Verfahrens gehört, dass die Messung der Position der Magnetpille in einer Druckform aufwändig und magnetische Messverfahren in der Drucktechnik unüblich sind. Darüber hinaus bedeutet die Vermessung des Druckplattenzylinders in einem externen Reck einen zusätzlichen Arbeitsgang, der zeit kostet und aufwändig ist.  The bodies are the magnetic pills in the printing forms. One of the disadvantages of such a method is that the measurement of the position of the magnetic pill in a printing form is complicated and magnetic measuring methods are unusual in printing technology. In addition, the measurement of the printing plate cylinder in an external stretching an additional operation, which costs time and is expensive.
Es ist Aufgabe der vorliegenden Erfindung, diese Nachteile zu beseitigen. It is an object of the present invention to eliminate these disadvantages.
Die Aufgabe wird durch die Beifügung der kennzeichnenden Merkmale zu einem Verfahren nach der EP 1 916 102 A1 gelöst. The object is achieved by the inclusion of the characterizing features to a method according to EP 1 916 102 A1.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. According to the invention, this object is solved by the features of the characterizing part of claim 1.
Demnach wird ein Körper oder eine Markierung auf die Druckform oder den Druckformträger aufgebracht. Im Falle der Markierung wird die Markierung wie eine Registermarke genutzt. Im Falle des Körpers ist eine Markierung beziehungsweise Registermarke auf den Körper aufgebracht. Aufgebracht im Sinne der vorliegenden Druckschrift heißt hierbei, dass er auf die Oberfläche des Druckformträgers gebracht wird und dort mit ihr verbunden wird. Hierbei kann eine feste Verbindung, wie eine Klebverbindung, gemeint sein. Accordingly, a body or a mark is applied to the printing form or the printing plate carrier. In the case of marking, the mark is used like a register mark. In the case of the body, a marking or register mark is applied to the body. Applied in the sense of the present document means in this case that it is brought to the surface of the printing form carrier and is connected there with her. Here, a solid compound, such as an adhesive bond, may be meant.
Der Körper oder die Markierung sollte in einer bestimmten bekannten Relativposition (zumindest einer Steuervorrichtung bekannten) zu dem Druckformträger oder der Druckplatte aufgebracht werden. Dann ist durch eine Feststellung der relativen Lage der Markierung oder des Körpers in dem Druckwerk, in dem der betreffende Druckplattenzylinder eingebracht wird, auch die Lage der Druckform zu ermitteln. The body or marking should be in a certain known relative position (at least one control device known) to the Printing plate or the printing plate are applied. Then, by determining the relative position of the marker or the body in the printing unit in which the printing plate cylinder is introduced, to determine the position of the printing plate.
Es ist vorteilhaft, den zusätzlichen Köper oder die Markierung beim Rüsten des Druckplattenzylinders auf die Druckform oder den Druckplattenzylinder aufzubringen. Diese Rüstvorgänge werden oft an sogenannten Mountern durchgeführt. Ein solcher Mounter wird unter anderem auch von der US 200601 17973 A1 gezeigt. In diese Vorrichtungen werden oft Dorne, Druckrollen oder Adaptersleeves eingespannt. Auf diese Körper werden dann oft Klischees aufgespannt beziehungsweise aufgeklebt. Es ist auch bekannt, weitere druckformtragende Sleeves zwischen den zuerst genannten Druckformträgern und den Klischees vorzusehen. It is advantageous to apply the additional body or the mark when equipping the printing plate cylinder on the printing plate or the printing plate cylinder. These setup processes are often performed on so-called mounters. Such a mounter is shown inter alia by US 200601 17973 A1. Mandrels, pressure rollers or adapter sleeves are often clamped in these devices. Clichés are then often clamped or glued onto these bodies. It is also known to provide further printing form-carrying sleeves between the first mentioned printing form carriers and the clichés.
Die Mounter sind mit optischen und mechanischen Vorrichtungen ausgestattet, die ein genaues Positionieren der Klischees auf der Oberfläche der Druckformträger erlauben. The mounters are equipped with optical and mechanical devices that allow accurate positioning of the clichés on the surface of the printing form carriers.
In der Regel ist auf den Klischees ein Referenzpunkt (oft Mikropunkt genannt) vorgesehen, der es erlaubt, das Klischee seinerseits genau zur Druckform zu positionieren. As a rule, a reference point (often called a microdot) is provided on the cliché, which allows the cliché in turn to be positioned exactly to the printing form.
Zur Ausführung des erfindungsgemäßen Verfahrens kann neben der genauen Positionierung des Klischees auf dem Druckformträger auch eine genaue Positionierung des zusätzlichen Körpers auf dem Druckformträger oder der Druckform vorgenommen werden.  For carrying out the method according to the invention, in addition to the exact positioning of the plate on the printing form carrier, an accurate positioning of the additional body on the printing plate carrier or the printing plate can be carried out.
In diesem Zusammenhang kann der zusätzliche Körper unter anderem auf die Oberfläche des Druckplattenzylinders, des Klisches oder anderer fest auf dem Druckplattenzylinder angebrachter Gegenstände angebracht werden. Als vorteilhaft wird hierbei angesehen, wenn der Körper oder auf dem Körper aufgebrachte Markierungen zu sehen sind, beziehungsweise wenn sie mit optischen Sesoren erkennbar sind. Der Terminus„optische Sensoren" schließt herbei auch Sensoren ein, die elektromagnetische Strahlung detektieren, die außerhalb des sichtbaren Bereichs liegen. Nichtsdestoweniger ist es vorteilhaft, Sensoren zu verwenden, die in dem Bereich des sichtbaren Lichtes empfindlich sind. In this connection, the additional body may be attached to, among other things, the surface of the printing plate cylinder, the plate, or other objects fixedly mounted on the printing plate cylinder. It is regarded as advantageous in this case if the body or markings applied to the body are to be seen, or if they can be seen with optical sesors. The term "optical sensors" also includes sensors that detect electromagnetic radiation that is out of the visible range, nonetheless it is advantageous to Use sensors that are sensitive in the visible light range.
Wenn handelsübliche Mounter geringfügig umgerüstet werden, sind andere Verfahren vorteilhaft: So können Markierungen durch Gravurwerkzeuge in die betreffende Oberfläche (wieder des Druckplattenzylinders, des Klisches oder anderer fest auf dem Druckplattenzylinder angebrachter Gegenstände) eingebracht werden. Vorteilhaft erscheint auch die Verwendung von Vorrichtungen, die die betreffenden Oberflächen bedrucken. So können in diesem Falle u. a. Tintenschreibköpfe - wie sie in Tintenstrahldruckern Verwendung finden - zum Einsatz kommen.  If commercially available mounters are slightly modified, other methods are advantageous: For example, markings can be introduced by engraving tools into the relevant surface (again the printing plate cylinder, the plate or other objects fixedly mounted on the printing plate cylinder). Also advantageous is the use of devices that print the surfaces concerned. So in this case u. a. Inkjet printheads - as used in inkjet printers - are used.
Vor allem bei der Verwendung von Gravier- und Druckverfahren lassen sich durch Automatisierungsvorgänge bei dem Aufbringen der Markierungen auch Genauigkeitsgewinne bei der Positionierung derselben erzielen. Herkömmliche Zentralzylinderflexodruckmaschinen sind zur Durchführung des erfindungsgemäßen Verfahrens nicht geeignet. Sie verfügen in der Regel über Registermarkensensoren, die allen Farbwerken nachgeschaltet sind. Sie nehmen eine Arbeitsposition ein, mit der sich der von mehreren oder besser allen Druckwerken bedruckte Bedruckstoff einsehen lässt. Sie inspizieren ein Registermarkenfeld, in dem von jedem Farbwerk eine Marke enthalten ist. Eine Druckmaschine, die das erfindungsgemäße Verfahren ausführt, muss die Relativposition (relative Winkellage) der Druckplattenzylinder (oder besser der Druckplatten beziehungsweise Klischees) zumindest zweier Farbwerke messen. Sie benötigt daher zumindest zwei Registermarkensensoren, die in eine Arbeitsposition zu den Druckplattenzylindern bringbar sind. Die Positionierung der Registermarkensensoren ist nicht unkritisch, da die Anforderungen an die Auflösung, die sich mit den Sensoren erzielen lassen muss, hoch ist. In der Regel wird die Arbeitsposition der Sensoren in Bereichen des Farbwerkes sein, in denen es zu Verschmutzungen der Sensoren durch Farbnebel und -Spritzer und ähnliches kommen kann. Daher ist es von Vorteil, wenn die Sensoren aus diesen Bereichen des Farbwerkes abtransportiert werden können. Die Sensoren können, wenn sie sich in der Arbeitsposition befinden, beispielsweise Messwerte für eine Vorreg isterung gewinnen. Sie können auch im laufenden Druckprozess Registermesswerte gewinnen. Letzteres wird insbesondere bei Zentralzylinderdruckmaschinen aber eher die Ausnahme sein. Especially when using engraving and printing processes can be achieved by automation processes in the application of the markers and accuracy gains in the positioning of the same. Conventional Zentralzylinderflexodruckmaschinen are not suitable for carrying out the method according to the invention. They usually have register mark sensors downstream of all inking units. They assume a working position with which the printing material printed by several or better of all printing units can be viewed. They inspect a register marker field, which contains a mark of each inking unit. A printing machine which carries out the method according to the invention has to measure the relative position (relative angular position) of the printing plate cylinders (or better of the printing plates or clichés) of at least two inking units. It therefore requires at least two register mark sensors, which can be brought into a working position to the printing plate cylinders. Positioning the register mark sensors is not uncritical because the resolution requirements that must be achieved with the sensors are high. In general, the working position of the sensors will be in areas of the inking unit, in which it can lead to contamination of the sensors by paint mist and splashing and the like. Therefore, it is advantageous if the sensors can be removed from these areas of the inking unit. The sensors can when they are in the working position for example, to obtain readings for a pre-registration. You can also gain register readings in the current printing process. The latter will be more of an exception, especially for central-cylinder printing presses.
Vorteilhafterweise wird die Transportvorrichtung die Registermarkensensoren um eine Drehachse aus den exponierten Bereichen des Farbwerkes herausschwenken. Es hat sich gezeigt, dass es vorteilhaft ist, diese Drehachse gegenüber dem Grundgestell des zugehörigen Farbwerks zu neigen (Winkel abweichend von 90 °). Advantageously, the transport device will pivot the register mark sensors about a rotation axis out of the exposed areas of the inking unit. It has been shown that it is advantageous to tilt this axis of rotation relative to the base frame of the associated inking unit (angle deviating from 90 °).
Die Registermarkensensoren 15 bzw. Sensorköpfe 14, die in in ihrer Arbeitsstellung durchaus mit Farbspritzern und Ähnlichem verunreinigt werden können, können in der abgeschwenkten Stellung unter anderem gereinigt werden. In einer abgeschwenkten Stellung kann eine Schutzeinhausung für den Sensor 15 oder zumindest den Sensorkopf 14 vorhanden sein. Diese Schutzeinhausung schützt den Sensor 15 oder zumindest den Sensorkopf 14 vor weiterer Verunreinigung. In einer solchen Schutzeinhausung kann der Sensor auch einen Abgleich vornehmen: So kann in der Schutzeinhausung eine Wand vorhanden sein, die genauso gefärbt wie z. B. ein Teil des zusätzlichen Körpers. Dann kann der Sensor prüfen, ob er von dieser Wand noch remittiertes Licht mit der ursprünglichen Intensität empfängt, wenn er - wie ursprünglich auch - Licht mit einer gewissen Intensität auf die Wand abgibt. Ist dies nicht mehr der Fall, so ist der Strahlungsausgang oder der Strahlungseingang des Sensors 15 oder zumindest des Sensorkopfes 14 (häufig wohl beides) verunreinigt.  The register mark sensors 15 and sensor heads 14, which may well be contaminated in their working position with paint splashes and the like, can be cleaned in the pivoted position among other things. In a pivoted position, a protective housing for the sensor 15 or at least the sensor head 14 may be present. This protective housing protects the sensor 15 or at least the sensor head 14 from further contamination. In such a protective housing, the sensor can also make a comparison: Thus, in the protective housing a wall may be present, the same colored as z. B. a part of the additional body. Then the sensor can check whether it receives light still of remit with the original intensity from this wall, if - as originally - it emits light with a certain intensity on the wall. If this is no longer the case, then the radiation output or the radiation input of the sensor 15 or at least of the sensor head 14 (often well both) is contaminated.
Aufgrund der Änderungen der Messwerte kann eine Steuer- und Recheneinheit den Sensor rekalibrieren. Eine Ergänzung oder Alternative zu diesem Vorgehen liegt in einer automatischen Reinigung, die beispielsweise beim Überschreiten einer gewissen Abweichung der Messwerte von dem Ausgangswert von der entsprechend eingestellten Steuer- und Recheneinheit vorgenommen werden kann. Die Steuer- und Recheneinheit kann jedoch auch ein Warnsignal an das Maschinenpersonal ausgeben, das dieses veranlasst, den Sensor 15 oder zumindest den Sensorkopf 14 zu reinigen. In Bezug auf den zusätzlichen Körper hat sich Folgendes als vorteilhaft erwiesen: Due to the changes in the measured values, a control and computing unit can recalibrate the sensor. A supplement or alternative to this procedure is an automatic cleaning, which can be carried out, for example, when a certain deviation of the measured values from the initial value is exceeded by the correspondingly set control and computing unit. However, the control and computing unit can also issue a warning signal to the machine personnel, which causes this to clean the sensor 15 or at least the sensor head 14. With regard to the additional body, the following has proven to be advantageous:
Es ist von Vorteil, wenn er auf die Oberfläche der Druckform oder des Druckformträgers aufgebracht werden kann. Hierzu kann der Körper eine flächige Form annehmen und beispielsweise wie ein Etikett auf diese Oberfläche aufgebracht werden. Körper, die eine flächige Form aufweisen, haben zwei große Oberflächen, also eine Vorder- und eine Rückseite. Die Rückseite des weiteren Körpers sollte mit der Druckform verbindbar sein. Die Vorderseite sollte die zumindest eine Registermarke tragen.  It is advantageous if it can be applied to the surface of the printing plate or the printing plate carrier. For this purpose, the body can assume a flat shape and, for example, be applied to this surface like a label. Bodies that have a flat shape have two large surfaces, ie a front and a back. The back of the other body should be connectable to the printing form. The front should carry the at least one register mark.
Der Körper kann beispielsweise ein Materialstreifen sein, dessen Längsachse vorzugsweise in Umfangsrichtung der Walze ausgerichtet wird. Auf dem Körper sind vorteilhafterweise eine gerade Anzahl von Markierungen beziehungsweise Marken aufgebracht. Eine symmetrische Gestaltung des Markenfeldes bezüglich eines Referenzpunktes ist von Vorteil und ermöglicht beispielsweise eine Differenzmessung. Des Weiteren kann man den Mittelwert zwischen Positionswerten zweier symmetrisch zu einem Referenzpunkt angeordneter Punkte ermitteln, um Messfehler, die von einer ungenauen Anordnung des Körpers zu der Druckform herrühren, in ihrer Wirkung zu minimieren. The body may for example be a strip of material whose longitudinal axis is preferably aligned in the circumferential direction of the roller. On the body advantageously an even number of marks or marks are applied. A symmetrical design of the marker field with respect to a reference point is advantageous and allows, for example, a difference measurement. Furthermore, the mean value between position values of two points arranged symmetrically with respect to a reference point can be determined in order to minimize the effect of measurement errors resulting from an inaccurate arrangement of the body to the printing form.
Es ist von Vorteil, sowohl rechteckige Marken oder Markierungen als auch dreieckige, trapezförmige oder kegelstumpfförmige zu verwenden. It is advantageous to use both rectangular marks or markings as well as triangular, trapezoidal or frusto-conical.
Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor. Further embodiments of the invention will become apparent from the description and the claims.

Fig. 6 Zusätzliche Körper 1 , die aus Handling- und Lagergründen auf ein Fig. 6 Additional body 1, for handling and storage reasons on a
Trägermaterial 28 aufgebracht wurden.  Carrier material 28 were applied.
Fig. 1 zeigt einen streifenförmig ausgeprägten zusätzlichen Körper 1 . Dieser trägt eine Mehrzahl von Marken 2, 2', 3, 3', 4, 4', 5, 5', die symmetrisch bezüglich des Bezugspunktes 6 angeordnet und geformt sind. Der streifenförmige Körper 1 ist dazu bestimmt, mit seiner Längsrichtung in Umfangsrichtung φ eines Formatzylinders 1 1 ausgerichtet zu werden. Die Anordnung und Ausrichtung des Streifens ermöglicht eine Differenzmessung zwischen den symmetrisch zu dem Referenzpunkt 6 angeordneten Punktpaaren n, n'. Durch diese Differenzmessung ist es möglich, Fehler, die durch Ungenauigkeiten in der Ausrichtung des Körpers auf dem Druckformträger oder der Druckform auftreten, zu minimieren. Die zur Umlaufrichtung φ des Formzylinders 1 1 schrägen Kanten der Marken 2 und 2' dienen der Seitenregisterung. Die anderen Marken werden unter anderem zur Längsregisterung eingesetzt. Es ist vorteilhaft, die Marken 2 und 2' schwarz und den Untergrund weiß zu gestalten. Vorteilhaft ist es auch, Marken mit einer Rechtecks- und/oder Dreiecksform vorzusehen. 1 shows a strip-shaped additional body 1. This carries a plurality of marks 2, 2 ', 3, 3', 4, 4 ', 5, 5', which are arranged and shaped symmetrically with respect to the reference point 6. The strip-shaped body 1 is intended to be aligned with its longitudinal direction in the circumferential direction φ of a format cylinder 1 1. The arrangement and orientation of the strip allows a differential measurement between the symmetrically arranged to the reference point 6 pairs of points n, n '. By this differential measurement, it is possible to minimize errors that occur due to inaccuracies in the orientation of the body on the printing plate or the printing form. The edges of the marks 2 and 2 ', which are oblique to the direction of rotation φ of the forme cylinder 11, serve for lateral registration. The other brands are used for longitudinal registration. It is advantageous to make the marks 2 and 2 'black and the background white. It is also advantageous to provide marks with a rectangular and / or triangular shape.
Figur 2 zeigt eine schematische Seitenansicht dreier Farbwerke 10 einer Zentralzylinderflexodruckmaschine 26. Typische Bauteile einer solchen Maschine sind der zentrale Gegendruckzylinder 13 sowie die Formatzylinder 1 1 und die Rasterwalzen 12 der einzelnen Farbwerke 10. Die Formatzylinder 1 1 und die Rasterwalzen 12 sind jeweils voneinander abgestellt. Die Pfeile 19 symbolisieren die Anstellrichtung der Zylinder. Des Weiteren sind die Sensorköpfe 14, die sich in Arbeitsstellung befinden, in Figur 2 zu sehen.  FIG. 2 shows a schematic side view of three inking units 10 of a central cylinder flexographic printing machine 26. Typical components of such a machine are the central impression cylinder 13 and the format cylinders 11 and the anilox rollers 12 of the individual inking units 10. The format cylinders 11 and the anilox rollers 12 are each offset from one another. The arrows 19 symbolize the Anstellrichtung the cylinder. Furthermore, the sensor heads 14, which are in working position, can be seen in FIG.
In Figur 3 ist der durch die Linie A-A gekennzeichnete Bereich eines Farbwerkes 10 aus der durch den Pfeil 20 skizzierten Blickrichtung zu sehen. In Figur 3 ist zusätzlich zu den bereits in Figur 2 gezeigten Merkmalen das Maschinengestell 17, das Klischee 18 sowie der Lichtleiter 16 und Sensor 15 zu sehen. In FIG. 3, the region of an inking unit 10 marked by the line A-A can be seen from the direction of view sketched by the arrow 20. In FIG. 3, in addition to the features already shown in FIG. 2, the machine frame 17, the cliché 18 as well as the light guide 16 and sensor 15 can be seen.
Figur 4 zeigt das Farbwerk 10 aus derselben Richtung wie Figur 3. Von der Transportvorrichtung 25 des Sensors beziehungsweise des Sensorkopfes 14 ist der Arm 22 und die Drehachse 23 zu sehen. Der Pfeil 24 zeigt die Schwenkrichtung des Sensorkopfes an. Wie erwähnt findet die Schwenkung um eine Achse 23 statt. Diese Achse ist auch in Figur 2 eingezeichnet. Bereits in Figur 2 ist zu sehen, dass der Winkel zwischen der Achse 22 und dem Grundgestell des Farbwerks 21 kein rechter Winkel ist. FIG. 4 shows the inking unit 10 from the same direction as FIG. 3. The arm 22 and the axis of rotation 23 can be seen from the transport device 25 of the sensor or the sensor head 14. The arrow 24 shows the Swivel direction of the sensor head. As mentioned, the pivoting takes place about an axis 23. This axis is also shown in FIG. Already in Figure 2 it can be seen that the angle between the axis 22 and the base frame of the inking unit 21 is not a right angle.
Die Sensorvorrichtung besteht insgesamt aus dem Sensorkopf 14, dem Lichtleiter 16 und dem Sensor 15. Eine solche Anordnung ist vorteilhaft, wenn es darum geht, den Sensorkopf 14 in einer chemisch kritischen Atmossphäre zu positionieren und den Sensor 15, mit seinen kritischen Bauteilen außerhalb dieses Bereiches zu platzieren. Der Sensorkopf kann dann das von den Registermarken 2, 2' beziehungsweise dem zusätzlichen Körper 1 oder anderer Teie des Formatzylinders 1 1 remittierte Licht auffangen und der Lichtleiter wird es dem Sensor 15 zuleiten. The sensor device as a whole consists of the sensor head 14, the light guide 16 and the sensor 15. Such an arrangement is advantageous when it comes to positioning the sensor head 14 in a chemically critical atmosphere and the sensor 15, with its critical components outside this range to place. The sensor head can then collect the light remitted by the register marks 2, 2 'or the additional body 1 or other part of the format cylinder 1 1 and the light guide will transmit it to the sensor 15.
Oft ist es vorteilhaft, in dem Gehäuse des Sensors 15 auch eine Lichtquelle anzuordnen, die dem Sensorkopf 14 über den Lichtleiter 15 auch Licht zuleitet, das der Ausleuchtung der Umgebung der Registermarken dient.  Often it is advantageous to arrange in the housing of the sensor 15, a light source, the light also feeds the sensor head 14 via the light guide 15, which serves to illuminate the environment of the register marks.
Figur 5 zeigt einen Formatzylinder 1 1 , der in einem nicht dargestellten Mounter eingespannt ist. In diesem Mounter ist bereits das Klischee 18 positionsgenau auf den Formatzylinder 1 1 aufgebracht worden. Oft dient zur Ausrichtung des Klischees eine oft imaginäre Linie 31 entlang der der Aufnahmebereich der Kamera oder Sehhilfe 7 bewegt werden kann, indem diese in ihren Bewegungsrichtungen 8 vorschoben wird. Die Kamera kann also Fixpunkte auf dem Formatzylinder „anfahren" (ihr fokusierter Fangbereich wird auf diesen Punkt eingestellt), indem sie in der axialen Richtung z des Formatzylinders verschoben wird und indem der Formatzylinder in seiner Umfangsrichtung φ gedreht wird. Die Veränderung der axialen Position z der Kamera 7 ist mit einem Längensensor messbar. Auch die Drehwinkeländerung des Formatzylinders ist mit einem Drehwinkelsensor des Mounters messbar, so dass bei bekanntem Durchmesser des Formatzylinders auch die Streckenbeträge in Umfangsrichtung φ zu ermitteln sind. Auf diese Weise können mit Hilfe des Mounters und seiner Kamera 7 Positionen in gewünschten Abständen voneinander auf der Oberfläche des Formatzylinders angefahren werden. Der Bediener des Mounters kann so das Klischee 18 und den zusätzlichen Körper 1 in einem Sollabstand voneinander positionieren (z. B. durch Ausrichten und Aufkleben). Durch ein automatiertes Aufbringen zum Beispiel von aufgedruckten Marken auf der Oberfläche des Zylinders 1 1 kann eine noch genauere Positionierung vorgenommen werden. Figure 5 shows a format cylinder 1 1, which is clamped in a Mounter, not shown. In this Mounter already the cliché 18 has been applied positionally accurate on the format cylinder 1 1. Often the orientation of the cliché is an often imaginary line 31 along which the receiving area of the camera or visual aid 7 can be moved by advancing them in their directions of movement 8. The camera can thus "approach" fixed points on the format cylinder (its focused catching area is set to this point) by being displaced in the axial direction z of the format cylinder and by rotating the format cylinder in its circumferential direction .phi .. The change in the axial position z The rotation angle change of the format cylinder can also be measured with a rotation angle sensor of the mounter so that, given a known diameter of the format cylinder, the distance amounts in the circumferential direction .phi. can also be determined 7 positions can be approached at desired distances from each other on the surface of the format cylinder.The operator of the mounter can thus position the cliché 18 and the additional body 1 at a desired distance from each other (for example by aligning and gluing) by an automated application to Example of printed marks on the surface of the cylinder 1 1 an even more accurate positioning can be made.
Als Fixpunkte auf dem Klischee werden oft sogenannte Mikropunkte 32 verwendet. Oft sind Formatzylinder 1 1 auf ihrer Antriebsseite (hier in Figur 5 links) mit einem Anschlag 27 versehen, gegen den ein Sleeve oder ein Klischee angestellt werden kann und der 27 den Aufschiebevorgang des SIeeves auf den Formatzylinder begrenzt. As fixed points on the cliché so-called microdots 32 are often used. Often, format cylinders 1 1 are provided on their drive side (here on the left in FIG. 5) with a stop 27 against which a sleeve or a cliché can be placed and which limits the sliding operation of the sleeve on the format cylinder.
In Figur 6 wird eine Mehrzahl von zusätzlichen Körpern 1 auf einem Bandmaterial 28 aufgebracht (die zusätzlichen Körper befinden sich aus Sicht des Betrachters im Vordergrund). Die zusätzlichen Körper 1 sind auf ihrer Rückseite selbstklebend. Sie können von dem Maschinenpersonal von dem Bandmaterial 28 abgezogen und auf den Formatzylinder 1 1 aufgebracht werden. Vorteilhaft ist es, das bandförmige Trägermaterial 28 zu perforieren oder in einer anderen Art zu schwächen, so dass Sollabrisslinien entstehen. Durch die horizontalen Perforationslinien 30 kann das Maschinenpersonal einzelne zusätzliche Körper 1 und das ihnen zugeordnete Trägermaterial 28 vereinzeln. Durch die vertikalen Perforationslinien 29 kann er sukzessive Teile der selbstklebenden Oberfläche der zusätzlichen Körper 1 freigeben.  In FIG. 6, a plurality of additional bodies 1 are applied to a strip material 28 (the additional bodies are in the foreground from the viewpoint of the observer). The additional body 1 are self-adhesive on its back. They can be deducted by the machine personnel from the strip material 28 and applied to the format cylinder 1 1. It is advantageous to perforate the band-shaped carrier material 28 or to weaken it in another way, so that predetermined tear lines are formed. Through the horizontal perforation lines 30, the machine personnel can separate individual additional body 1 and their associated carrier material 28. By means of the vertical perforation lines 29, it can release successive parts of the self-adhesive surface of the additional bodies 1.
Das bandförmige Material 28 kann mit den zusätzlichen Körpern zu Rollen aufgewickelt werden. Eine solche Rolle bringt viele Vorteile mit sich. The band-shaped material 28 can be wound up into rolls with the additional bodies. Such a role brings many benefits.
Es ist vorteilhaft, alle vorstehend beschriebenen und beanspruchten Verfahren oder Verfahrensschritte computerimplementiert durchzuführen. Demzufolge ist eine Steuereinheit vorzusehen, die so eingestellt ist, dass sie Maschinenkomponenten zur Ausführung der Verfahren ansteuert. It is advantageous to carry out all the methods and method steps described above and claimed in a computer-implemented manner. Accordingly, a control unit is provided which is set to drive machine components to carry out the methods.
