Insbesondere im Mehrfarbendruck ist es für die Qualität eines herzustellenden Druckerzeugnisses wichtig, dass am Druck desselben Druckbildes beteiligte Druckformen in im Druckprozess einander nachfolgenden Druckwerken einer Druckmaschine registerhaltig an ihrem jeweiligen Formzylinder angeordnet sind, um voneinander verschiedene, von unterschiedlichen Druckwerken gedruckte, aber zu demselben Druckbild gehörende Farbauszüge des Druckerzeugnisses auf dem Bedruckstoff passgenau aufeinander zu drucken. Um eine registerhaltige, insbesondere seitenregisterhaltige Ausrichtung und Zuführung von Druckformen zu ihrem jeweiligen Formzylinder zu ermöglichen, werden die am Druckprozess beteiligten Druckformen folgendermaßen vorbereitet.Particularly in multi-color printing, it is important for the quality of a printed product to be printed on the same printed image in successive printing units of a printing press in register printing on their respective form cylinder are arranged to different from each other, printed by different printing units, but belonging to the same print image Color separations of the printed product on the substrate to print accurately to each other. In order to enable a register-containing, in particular page register-containing alignment and feeding of printing plates to their respective form cylinder, the printing forms involved in the printing process are prepared as follows.

Eine z. B. in einem Offsetdruckverfahren einzusetzende Druckform 02 wird derart hergestellt, dass eine Rohdruckform mit einem Druckbild bebildert (Fig. 2 und 3) und ihre Form dem beabsichtigten Einsatz in einer Druckmaschine angepasst wird. Die Rohdruckform kann z. B. aus einer dünnen, flexiblen, rechteckförmigen Platte bestehen, wobei deren Längen- und Breitenmaß eine Toleranz von z. B. ± 1 mm aufweisen kann. Diese große Toleranz ist insbesondere für im Mehrfarbendruck einzusetzende Druckformen 02 nicht akzeptabel, da Register im Druckprozess, z. B. Seitenregister, Umfangsregister, Farbregister, z. B. mit einer Genauigkeit zwischen 0,005 mm und 0,03 mm, vorzugsweise zwischen 0,01 mm und 0,02 mm eingestellt sein müssen, um ein qualitativ akzeptables Druckerzeugnis mit einem Druckbild ausreichender Bildschärfe herzustellen.A z. B. to be used in an offset printing method printing form 02 is prepared such that a Rohdruckform imaged with a printed image ( Fig. 2 and 3 ) and their shape is adapted to the intended use in a printing press. The Rohdruckform can z. B. consist of a thin, flexible, rectangular plate, wherein the length and width dimension of a tolerance of z. B. ± 1 mm can have. This large tolerance is unacceptable, in particular for printing plates 02 to be used in multicolor printing, since registers in the printing process, e.g. B. page register, circumferential register, color register, z. B. with an accuracy between 0.005 mm and 0.03 mm, preferably between 0.01 mm and 0.02 mm must be set to produce a qualitatively acceptable printed product with a print image of sufficient image sharpness.

Die zu bebildernde Fläche der Druckform 02 ist ihre Arbeitsfläche. Die Arbeitsfläche der Druckform 02 wird innerhalb eines durch zwei parallele Linien begrenzten Satzspiegels 11 durch eine Bebilderungsvorrichtung oder in einer Bebilderungsvorrichtung mit einem Druckbild z. B. fotografisch bebildert. Die zwei parallelen Linien 12; 13 des Satzspiegels 11 sind dabei parallel zur Transportrichtung eines das Druckbild im Druckprozess in der Druckmaschine aufnehmenden Bedruckstoffes ausgerichtet. Es wird zumindest eine Kante 14 der Druckform 02 nach der Bebilderung der Arbeitsfläche parallel zu den beiden parallelen Linien 12; 13 des Satzspiegels 11 beschnitten. Vorzugsweise werden zwei parallele Kanten 14; 16 der Druckform 02 nach der Bebilderung der Arbeitsfläche parallel zu den beiden parallelen Linien 12; 13 des Satzspiegels 11 beschnitten. Damit erfolgt der Beschnitt der zumindest einen Kante 14; 16 der Druckform 02 in Abhängigkeit von dem auf der Druckform 02 aufgebrachten Druckbild, sodass mindestens diese eine Kante 14; 16 stets parallel zum Satzspiegel 11 ausgerichtet ist. Die beschnittene Kante 14; 16 hat also immer einen festen Bezug zu dem auf der Druckform 02 aufgebrachten Druckbild. Diese Maßnahme ist vorteilhaft, da dadurch ein registerhaltiges Ausrichten des Druckbildes erleichtert wird. Wenn sichergestellt ist, dass die Druckform 02 exakt parallel zur Transportrichtung des das Druckbild aufnehmenden Bedruckstoffes einem Formzylinder 01 der Druckmaschine zugeführt und auf dem Formzylinder 01 montiert wird, werden am Formzylinder 01 für die Registereinstellung der Druckform 02 entsprechende Einstellvorrichtungen, z.

The working surface of the printing plate 02 is within a set by two parallel lines set level 11 by an imaging device or in an imaging device with a printed image z. B. photographically illustrated. The two parallel lines 12; 13 of the type area mirror 11 are aligned parallel to the transport direction of a printing image in the printing process receiving the printing material in the printing process. There is at least one edge 14 of the printing plate 02 after the imaging of the working surface parallel to the two parallel lines 12; 13 of the sentence mirror 11 cropped. Preferably, two parallel edges 14; 16 of the printing plate 02 after the imaging of the working surface parallel to the two parallel lines 12; 13 of the sentence mirror 11 cropped. Thus, the trimming of the at least one edge 14 takes place; 16 of the printing plate 02 as a function of the pressure applied to the printing plate 02 print image, so that at least this one edge 14; 16 is always aligned parallel to the type area 11. The trimmed edge 14; Thus, 16 always has a fixed relation to the printed image applied on the printing form 02. This measure is advantageous, as a register-based alignment of the printed image is facilitated thereby. If it is ensured that the printing plate 02 exactly parallel to the transport direction of the printing image receiving substrate is fed to a forme cylinder 01 of the printing press and mounted on the forme cylinder 01, the form cylinder 01 for the register setting of the printing plate 02 corresponding adjusting devices, for.

Both with respect to the cross member 27 rigid stop with the reference numeral 06 and with respect to the cross member 27 axially movable stop with the reference numeral 07 can be configured in the axial direction of the cross member 27 at least within a certain adjustment range and thus adjustable. Their property of being rigid or axially movable relates only to those operating conditions in which they laterally align and / or guide a printing forme 02 to be fed to the forme cylinder 01 during the feeding process.

In dem in den Fig. 4 bis 6 gezeigten Beispiel ist im Inneren der Traverse 27 jeweils an jedem Lager 31 eines in axialer Richtung des Formzylinders 01 beweglichen Anschlags 07 eine Linearführung 33 vorgesehen, wobei der in axialer Richtung des Formzylinders 01 bewegliche Anschlag 07 jeweils mit dem beweglichen Teil der Linearführung 33 fest verbunden ist. In axialer Richtung des Formzylinders 01 nicht beweglich ausgebildete Anschläge 06 sind nach ihrer vorab gewählten axialen Positionierung mit der Traverse 27 fest verbunden. Die Traverse 27 weist an den Positionen der beweglichen Anschläge 07 jeweils eine Öffnung 34, z. B. ein in axialer Richtung des Formzylinders 01 gerichtetes Langloch 34 auf, um den jeweiligen beweglichen Anschlag 07 mit der im Inneren der Traverse 27 angeordneten Linearführung 33 zu verbinden. Das Federelement 32 ist innerhalb der Linearführung 33 oder stirnseitig an der Linearführung 33 angeordnet und an einer Seite mit einer gegenüber der Traverse 27 nicht beweglichen Halterung 36 verbunden (Fig. 7). Das Federelement 32 ist z. B. als eine Feder 32, insbesondere als eine schraubenförmige, zylindrische oder als eine tellerförmige Feder 32, als ein federelastischer Körper 32, z. B. ein ausreichend weicher Gummipuffer, oder als eine z. B. aus zwei zusammenwirkenden Federblechen bestehende Parallelogrammverschiebung ausgebildet. Ein in axialer Richtung des Formzylinders 01 gerichteter Federweg des Federelementes 32 liegt z. B. im Bereich von ± 0,5 mm bis ca. 2 mm, vorzugsweise ± 0,5 mm bis 1 mm. Das Federelement 32 ist vorzugsweise vorgespannt.In the in the 4 to 6 As shown, a linear guide 33 is provided in the interior of the traverse 27 on each bearing 31 of a movable stop 07 in the axial direction of the forme cylinder 01, wherein the stop 07 movable in the axial direction of the forme cylinder 01 is fixedly connected to the movable part of the linear guide 33 , In the axial direction of the forme cylinder 01 not movably formed stops 06 are fixedly connected to their pre-selected axial positioning with the traverse 27. The traverse 27 has at the positions of the movable stops 07 each have an opening 34, z. B. a directed in the axial direction of the forme cylinder 01 slot 34 to connect the respective movable stop 07 with the arranged inside the traverse 27 linear guide 33. The spring element 32 is disposed within the linear guide 33 or frontally on the linear guide 33 and connected on one side with a respect to the cross member 27 not movable bracket 36 ( Fig. 7 ). The spring element 32 is z. B. as a spring 32, in particular as a helical, cylindrical or as a plate-shaped spring 32, as a resilient body 32, z. B. a sufficiently soft rubber buffer, or as a z.

B. in the range of ± 0.5 mm to about 2 mm, preferably ± 0.5 mm to 1 mm. The spring element 32 is preferably biased.

Die Linearführung 33 lässt sich innerhalb eines durch den Federweg des Federelementes 32 vorgegebenen, maximal zulässigen Verschiebungsweges durch eine an den mit der Linearführung 33 verbundenen beweglichen Anschlag 07 in axialer Richtung des Formzylinders 01 angreifende Kraft verschieben, was in der Fig. 7 jeweils durch einen parallel zur Traverse 27 gerichteten Doppelpfeil am beweglichen Anschlag 07 angedeutet ist, wodurch eine z. B. fertigungsbedingte Schwankung der sich in axialer Richtung des Formzylinders 01 erstreckenden Breite der dem Formzylinder 01 zuzuführenden Druckform 02 bedarfsgerecht ausgleichbar ist und ein Verklemmen der zuzuführenden Druckform 02 während ihrer Zuführung zum Formzylinder 01 vermieden werden kann. Trotz der Flexibilität, d. h. der Verschiebbarkeit des mit der Linearführung 33 verbundenen beweglichen Anschlags 07 erhält die dem Formzylinder 01 zuzuführende Druckform 02 aufgrund der federelastischen Lagerung dieses beweglichen Anschlags 07 eine ausreichende seitliche Stabilität für ihre registerhaltige Zuführung zum Formzylinder 01. Die zumindest eine in Relation zum Druckbild der Druckform 02 beschnittene Kante 14; 16 dieser Druckform 02 wird durch den federelastisch gelagerten beweglichen Anschlag 07 zuverlässig an dem hinsichtlich der Traverse 27 starren Anschlag 06 sowohl seitlich ausgerichtet als auch während des Zuführens dieser Druckform 02 an diesem starren Anschlag 06 geführt.The linear guide 33 can be within a predetermined by the spring travel of the spring element 32, maximum displacement displacement by a force associated with the linear guide 33 movable stop 07 in the axial direction of the forme cylinder 01 moving force, which in the Fig. 7 each indicated by a parallel to the traverse 27 directed double arrow on the movable stop 07, whereby a z. B. production-related fluctuation of extending in the axial direction of the forme cylinder 01 width of the forme cylinder 01 supplied printing forme 02 can be compensated as needed and jamming of the supplied printing forme 02 during its supply to the forme cylinder 01 can be avoided. Despite the flexibility, ie the displaceability of the movable guide 07 connected to the linear guide 33 receives the forme cylinder 01 supplied printing forme 02 due to the resilient mounting of this movable stop 07 sufficient lateral stability for their register-containing supply to the forme cylinder 01. The at least one in relation to Printed image of the printing plate 02 cut edge 14; 16 of this printing forme 02 is reliably aligned by the resiliently mounted movable stop 07 on the stop 27, which is rigid with respect to the traverse 27, both laterally aligned and during the feeding of this printing forme 02 to this rigid stop 06.

Zumindest der in axialer Richtung des Formzylinders 01 beweglich gelagerte Anschlag 07 kann an seiner der dem Formzylinder 01 zuzuführenden Druckform 02 zugewandten Seite für diese Druckform 02 eine Führungshilfe z. B. in Form einer in die Anschlagsfläche eingelassenen oder angeformten Nut aufweisen. Der in axialer Richtung des Formzylinders 01 beweglich gelagerte Anschlag 07 ist z. B. als ein lotrecht von der Traverse 27 abstehender Stift oder Steg ausgebildet, wohingegen der mit der Traverse 27 starr verbundene Anschlag 06 winkelförmig mit einer vergleichsweise großen, der dem Formzylinder 01 zuzuführenden Druckform 02 zugewandten Führungsfläche ausgebildet ist.At least in the axial direction of the forme cylinder 01 movably mounted stop 07 can on its side facing the forme cylinder 01 printing form 02 side facing for this printing form 02 a guide z. B. in the form of embedded in the stop surface or molded groove. The movable in the axial direction of the forme cylinder 01 stop 07 is z. B. formed as a perpendicular from the traverse 27 projecting pin or web, whereas the rigidly connected to the cross member 27 stop 06 is angularly formed with a comparatively large, the forme cylinder 01 to be supplied to the printing plate 02 facing guide surface.

Die dem Formzylinder 01 zuzuführende Druckform 02 wird während des Zuführvorgangs, d. h. während ihrer zum Formzylinder 01 gerichteten Transportbewegung, zwischen den Anschlägen 06; 07 in vorzugsweise gleitendem Berührungskontakt mit diesen Anschlägen 06; 07 hindurchgeführt. Dabei übt die Druckform 02 einerseits auf den in axialer Richtung des Formzylinders 01 beweglich gelagerten Anschlag 07 gegen das Federelement 32 eine Kraft aus, andererseits wird diese Druckform 02 in Reaktion auf ihre Abstützung an dem in axialer Richtung des Formzylinders 01 beweglich gelagerten Anschlag 07 während ihrer zum Formzylinder 01 gerichteten Transportbewegung gegen den für diese Druckform 02 wirksamen, hinsichtlich der Traverse 27 starr angeordneten Anschlag 06 gedrückt. Durch ein Zusammenwirken der mit den Anschlägen 06; 07 ausgebildeten Vorrichtung 04 zum Führen der Druckform 02 mit der registerhaltig hergestellten Druckform 02 kann eine zumindest seitenregistergenaue Positionierung der Druckform 02 auf der Mantelfläche eines Formzylinders 01 erreicht werden, weil durchgängig durch den gesamten Montagevorgang ein fester Bezug zwischen dem auf der Druckform 02 durch die Bebilderung aufgebrachten Druckbild und der mithilfe der Anschläge 06; 07 vorgenommenen Positionierung dieser Druckform 02 auf dem Formzylinder 01 bestehen bleibt.The printing forme 02 to be supplied to the forme cylinder 01 is moved during the feeding process, ie during its transport movement directed towards the forme cylinder 01, between the stops 06; 07 in preferably sliding contact with these stops 06; 07 passed. In this case, the printing plate 02 exerts on the one hand on the movable in the axial direction of the forme cylinder 01 stop 07 against the spring element 32 a force, on the other hand, this printing plate 02 in response to their support on the axially movable in the axial direction of the forme cylinder 01 stop 07 during their directed to the forme cylinder 01 transport movement against the effective for this printing plate 02, with respect to the cross member 27 rigidly arranged stop 06 pressed. By an interaction of the with the attacks 06; 07 trained device 04 for guiding the printing plate 02 with the printing plate 02 produced in register can be achieved at least Seitenenregister accurate positioning of the printing plate 02 on the outer surface of a forme cylinder 01, because consistently through the entire assembly process, a fixed relationship between that on the printing plate 02 by the imaging Applied printed image and the help of the stops 06; 07 made positioning this printing forme 02 on the forme cylinder 01 remains.
