Description

Die Erfindung betrifft ein Verfahren zur Beeinflussung einer aus einer Druckfarbe und einem Feuchtmittel bestehenden Emulsion in einer Druckmaschine und eine zur Durchführung des Verfahrens geeignete Druckmaschine.The invention relates to a method for influencing a printing ink and an existing dampening solution emulsion in a printing press and a Carrying out the process of suitable printing press.

Kurzzeitige Veränderungen der zwischen Walzen einer Druckmaschine vorhandenen Pressung oder Umfangsoberflächengeschwindigkeitsdifferenz können vom Überrollen eines Zylinderkanals eines Druckformzylinders durch eine Auftragswalze oder vom Aufschlagen einer Heberwalze auf eine Walze oder durch ähnliche stoßartige Be- und Entlastungen eines Farb- oder Peuchtwerkes verursacht werden. Die Veränderungen haben in Emulsionsfilmen auf den von den Veränderungen betroffenen beiden Walzen streifenförmige Emulsionsstörungen zur Folge, welche von den Walzen auf eine Druckform des Druckformzylinders übertragen werden und die Druckqualität erheblich mindern.Brief changes in the existing between the rollers of a printing press Pressing or circumferential surface speed difference can result from rollover of a cylinder channel of a printing form cylinder through an application roller or from Hitting a jack roller on a roller or by similar shock-like loading and Relief of a paint or dampening system can be caused. The changes have in emulsion films on the two rollers affected by the changes streak-shaped emulsion disturbances result, which from the rollers on a Printing form of the printing form cylinder are transferred and the print quality considerably reduce.

Um diesem Problem zu begegnen wurden bisher die Stöße und deren Weiterleitung unterdrückende Maßnahmen, wie z. B. die Stöße elastisch und dämpfend aufnehmende Walzenbezüge und besonders steife Walzenlagerungen, in Betracht gezogen. Durch diese Maßnahmen konnten die Emulsionsstreifen nicht im erhofften Maße reduziert werden.So far, the bumps and their forwarding have been used to counter this problem suppressive measures, such as B. the shocks elastic and absorbing Roll covers and particularly stiff roller bearings are taken into account. Through this Measures could not be reduced to the extent hoped for.

Die Anwendung von Ultraschallwellen in Druckmaschinen ist grundsätzlich bekannt, jedoch nicht mit Bezug auf die vorstehend erläuterte Problematik.The use of ultrasonic waves in printing machines is generally known but not with reference to the problems explained above.

Beispielsweise ist in der WO 91/18744 ein Verfahren zur Beseitigung von Gasblasen in einer für Flexo- oder Tiefdruck verwendeten Druckfarbe beschrieben, bei welchem Ultraschallenergie in die Druckfarbe geleitet und auf diese Weise die Schaumbildung verringert wird. Die Ultraschallenergie kann über Anilox- oder Tiefdruckwalzen, Farbwannen oder mit Ultraschall-Aktuaturen ausgerüstete Kammerrakeln der Druckfarbe zugeführt werden. For example, WO 91/18744 describes a method for removing gas bubbles in a printing ink used for flexographic or gravure printing, in which Ultrasound energy is directed into the printing ink and in this way foaming is reduced. The ultrasonic energy can be anilox or gravure rollers, Ink trays or chambered doctor blades of the printing ink equipped with ultrasonic actuators are fed.

Ein weiteres Beispiel für die Verwendung von Ultraschallwellen in Druckmaschinen ist ein in der JP-SHO 62-134264 beschriebenes Verfahren zur Zufuhr einer Druckfarbe an eine Tiefdruckform, bei welchem gemäß einer von mehreren Ausführungsformen von einer Linse gebündelte Ultraschallwellen auf die Tiefdruckform gerichtet werden. Eine aus der Druckfarbe und einem Feuchtmittel bestehende Emulsion wird beim Tiefdruck bekanntermaßen nicht verwendet.Another example of the use of ultrasonic waves in printing machines is a in JP-SHO 62-134264 described method for supplying an ink to a Gravure form, in which according to one of several embodiments of one Lens-focused ultrasonic waves are directed onto the gravure form. One from the Printing ink and a dampening solution emulsion is used in gravure printing known not to be used.

Ein anderes Beispiel für die Verwendung von Ultraschallwellen in Druckmaschinen ist in der DE 29 48 486 A1 beschrieben. Bei dem darin beschriebenen Farb- und Feuchtwerk ist die Oberfläche von auf einer Walze befindlichen Farb- und/oder Farb-Feuchtflüssigkeitsschichten durch mittels einer Ultraschallquelle erzeugte Schwingungen deformier- und/oder aufreißbar, um die Freigabe und nicht das Emulgieren von in der Farbe eingeschlossenem Wasser zu befördern und dem Auftreten sogenannter Farb-Wasser-Emulsionsnester entgegenzutreten. Das freigegebene Wasser kann mit einer Trockenvorrichtung behandelt werden.Another example of the use of ultrasonic waves in printing machines is in described in DE 29 48 486 A1. In the inking and dampening system described therein the surface of ink and / or ink dampening liquid layers located on a roller by vibrations generated by an ultrasound source deformable and / or tearable to release and not emulsify in the To convey paint trapped water and the occurrence of so-called paint-water emulsion nests counter. The released water can with a Dryer to be treated.

Noch ein weiteres Beispiel für die Verwendung von Ultraschallwellen in Druckmaschinen ist ein in der JP-HEI 3-90359 beschriebenes Verfahren zur Steuerung des Wassergehaltes einer Druckfarbeemulsion eines Farbwerkes. Bei diesem Verfahren wird mittels eines in einer Wasserabspaltungseinrichtung angeordnete Ultraschallschwingers die Druckfarbeemulsion einerseits in Druckfarbe und andererseits in Wasser separiert. Während der Separation befindet sich die Druckfarbeemulsion auf keiner Walze des Farbwerkes, sondern in der Wasserabspaltungseinrichtung.Yet another example of the use of ultrasonic waves in printing machines is a method for controlling the water content described in JP-HEI 3-90359 a printing ink emulsion of an inking unit. In this method, an in a water splitting device arranged ultrasonic vibrators Ink emulsion separated on the one hand in printing ink and on the other hand in water. During the separation, the ink emulsion is not on any roller of the Inking unit, but in the water elimination device.

Ferner ist in der DE 198 27 295 A1 eine Dosiereinrichtung für ein flüssiges Medium beschrieben, bei welcher das Medium mittels eines Vibrationselementes in Vibration versetzt wird. Das Vibrationselement kann als ein auf die Oberfläche einer Schöpfwalze wirkender Ultraschallgeber ausgebildet sein. Das Medium ist entweder Lack oder Feuchtmittel und in keinem Fall eine aus einer Druckfarbe und einem Feuchtmittel bestehende Emulsion. Furthermore, in DE 198 27 295 A1 there is a metering device for a liquid medium described, in which the medium vibrates by means of a vibration element is transferred. The vibrating element can be applied to the surface of a scoop roller acting ultrasound transmitter. The medium is either lacquer or Fountain solution and in no case one from a printing ink and a fountain solution existing emulsion.

Die vorstehend genannten Schriften (WO 91/18744, JP-SHO 62-134264, DE 29 48 486 A1, JP-HEI 3-90359, DE 198 27 295 A1) geben somit keinerlei Anregungen zur Lösung der eingangs geschilderten Problematik (streifenförmige Emulsionsstörungen) und bilden bezüglich der Erfindung lediglich ferneren Stand der Technik.The above-mentioned documents (WO 91/18744, JP-SHO 62-134264, DE 29 48 486 A1, JP-HEI 3-90359, DE 198 27 295 A1) therefore give no suggestions for solving the problem problem described at the beginning (strip-like emulsion disorders) and form only further state of the art with respect to the invention.

Deshalb liegt der Erfindung die Aufgabe zu Grunde, ein Verfahren anzugeben, durch welches die Druckqualität verbessert wird, und mindestens eine für die Durchführung des Verfahrens geeignete Druckmaschine zu schaffen.Therefore, the invention is based on the object of specifying a method by which will improve print quality, and at least one for performing the Process suitable press to create.

Die gestellte Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und durch eine Druckmaschine mit den Merkmalen des Anspruchs 3 gelöst.The object is achieved by a method having the features of claims 1 and solved by a printing press with the features of claim 3.

Beim erfindungsgemäßen Verfahren zur Beeinflussung einer aus einer Druckfarbe und einem Feuchtmittel bestehenden Emulsion auf einer Walze in einer Druckmaschine werden in die auf der Walze befindliche Emulsion Schwingungen eingeleitet, die mittels eines Schwingungserregers der Druckmaschine erzeugt werden, der dazu mit einer Ultraschall entsprechenden Frequenz schwingt, wobei die Walze mittels des Schwingungserregers in Schwingungen versetzt wird, welche Axialschwingungen der Walze sind.In the method according to the invention for influencing a printing ink and an existing dampening solution emulsion on a roller in a printing press vibrations are introduced into the emulsion on the roller Vibration exciter of the printing machine are generated, which is done with an ultrasound corresponding frequency vibrates, the roller by means of the vibration exciter in Vibrations is offset, which are axial vibrations of the roller.

Der Erfindung liegt die Erkenntnis zu Grunde, dass unter der Voraussetzung, dass sich die Emulsion dabei als ein dünner Emulsionsfilm auf einer Umfangsoberfläche der Walze befindet, ein Emulgieren mittels des mit der Ultraschallfrequenz schwingenden Schwingungserregers befördert werden kann. Diese Erkenntnis steht im krassen Gegensatz zum aus der JP-Hei 3-90359 bekannten Verfahren, bei welchem mittels des Ultraschalls ein Demulgieren befördert werden soll.The invention is based on the knowledge that, provided that the Emulsion as a thin emulsion film on a peripheral surface of the roller is an emulsification by means of the vibrating with the ultrasonic frequency Vibration exciter can be transported. This finding is in stark contrast to the method known from JP-Hei 3-90359, in which by means of ultrasound demulsification is to be promoted.

Die erfindungsgemäße Druckmaschine mit einer eine aus einer Druckfarbe und einem Feuchtmittel bestehende Emulsion fiihrenden Walze ist zur Durchführung des erfindungsgemäßen Verfahrens geeignet und zeichnet sich dadurch aus, dass der Walze ein diese in Schwingungen versetzender und mit einer Ultraschall entsprechenden Frequenz schwingender Schwingungserreger zugeordnet ist und dass die Walze aus einer Walzenachse und einer die Emulsion führenden Walzenhülse besteht, welche durch den Schwingungserreger in Längsrichtung der Walzenachse zum Schwingen anregbar auf der Walzenachse gelagert ist.The printing press according to the invention with a one of a printing ink and one Emulsion-carrying roller is used to carry out the dampening solution Suitable method and is characterized in that the roller this vibrating frequency and corresponding with an ultrasound vibrating vibration exciter is assigned and that the roller from a Roller axis and a roller sleeve leading the emulsion, which by the Vibration exciter in the longitudinal direction of the roller axis can be excited to vibrate on the Roll axis is mounted.

Durch die Schwingungen der Walze und der auf dieser befindlichen Emulsion wird das Emulgieren des Feuchtmittels mit der Druckfarbe auf dem gesamten Teil der von der Emulsion bedeckten Umfangsoberfläche der Walze verbessert. Ein die Walze oder mehrere derartig zum Schwingen angeregte Walzen umfassendes Farbwerk benötigt insgesamt weniger Walzen als ein konventionelles Farbwerk, um die Druckfarbe aufzubereiten.This is due to the vibrations of the roller and the emulsion on it Emulsify the fountain solution with the ink on the entire part of the ink Emulsion covered peripheral surface of the roller improved. One or more An inking unit comprising rollers which are excited to vibrate in this way requires a total fewer rollers than a conventional inking unit to process the printing ink.

Eine Weiterbildung der erfindungsgemäßen Druckmaschine zeichnet sich dadurch aus, dass neben der Walze mindestens eine auf die Walze gerichtete Ultraschallquelle angeordnet ist. Durch Ultraschallwellen der Ultraschallquelle, welche auf die Emulsion auf der rotierenden Walze treffen, wird das Emulgieren ebenfalls verbessert. Streifenförmige Emulsionsstörungen werden durch die Ultraschallwellen beseitigt, noch bevor die Emulsionsstörungen in einer dem Schablonieren ähnlichen Weise von der Walze auf eine andere Walze oder eine Druckform übertragen werden können.A further development of the printing press according to the invention is characterized in that that in addition to the roller, at least one ultrasound source directed onto the roller is arranged. By ultrasonic waves from the ultrasonic source, which are applied to the emulsion the rotating roller, the emulsification is also improved. Banded Emulsion disorders are eliminated by the ultrasonic waves even before the Emulsion disturbances in a manner similar to stenciling from the roller in one other roller or a printing form can be transferred.

Funktionell und konstruktiv vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Druckmaschine sind in den Unteransprüchen genannt und ergeben sich aus der nachfolgenden Beschreibung und der dazugehörigen Zeichnung:Functionally and constructively advantageous developments of the invention The method and the printing press according to the invention are in the subclaims named and result from the following description and the associated Drawing:

In der Figur 1 ist eine Druckmaschine 1 im Ausschnitt dargestellt. Der Ausschnitt zeigt einen Druckformzylinder 2 mit einer Druckform 3, auf welcher eine Walze 4 als eine Auftragswalze abrollt. Die Druckform 3 ist eine Flachdruckform (Planographic Printing Form) für den Offsetdruck. Die gummibezogene, weich-elastische Walze 4 und eine letztere frikativ antreibende Walze 5 sind Bestandteile eines nur ausschnittsweise gezeigten Farbwerkes 6 der Druckmaschine 1. Letztere enthält zur Einfeuchtung der Druckform 3 ein aus Walzen bestehendes Feuchtwerk, welches bekannter Art ist und deshalb nicht dargestellt werden braucht. Die verchromte, harte Walze 5 ist eine axial changierende Reibwalze.A printing machine 1 is shown in detail in FIG. The section shows a printing form cylinder 2 with a printing form 3, on which a roller 4 as one Application roller rolls off. Printing form 3 is a planographic printing form (Planographic Printing Form) for offset printing. The rubber-covered, soft-elastic roller 4 and one the latter frictionally driving roller 5 are components of a section shown only Inking unit 6 of the printing press 1. The latter contains 3 for moistening the printing form dampening system consisting of rollers, which is of a known type and therefore not needs to be represented. The chrome-plated, hard roller 5 is an axially iridescent Friction roller.

In Drehrichtung des Druckformzylinders 2 gesehen, liegt die Walze 4 als letzte Walze des Farbwerks 6 vor einem Gummituchzylinder 7 an der Druckform 3 an. Ein der Walze 4 zugeordneter und als eine Ultraschallquelle 8 ausgebildeter Schwingungserreger der Druckmaschine 1 ist auf einen Umfangsbereich der Walze 4 fokussiert, welcher in Drehrichtung der Walze 4 gesehen einer gemeinsamen Kontaktlinie der Walzen 4 und 5 nachgeordnet und einer gemeinsamen Kontaktlinie 10 der Walze 4 und der Druckform 3 vorgeordnet ist. Die Kontaktlinie 9 ist eine Flüssigkeitsannahmelinie und die Kontaktlinie 10 eine Flüssigkeitsabgabelinie der Walze 4. Die Ultraschallquelle 8 ist aus Piezo-Elementen 11, 12, 13 zusammengesetzt und erstreckt sich über die von einer filmförmigen Druckfarbe-Feuchtmittelemulsion 14 bedeckte Axiallänge der Walze 4.Seen in the direction of rotation of the printing form cylinder 2, the roller 4 is the last roller of the Inking unit 6 in front of a blanket cylinder 7 on the printing form 3. One of the roller 4 assigned and designed as an ultrasound source 8 vibration exciter Printing machine 1 is focused on a peripheral region of the roller 4, which in Direction of rotation of the roller 4 seen a common contact line of the rollers 4 and 5th downstream and a common contact line 10 of the roller 4 and the printing form 3rd is upstream. The contact line 9 is a liquid acceptance line and the Contact line 10 is a liquid discharge line of the roller 4. The ultrasound source 8 is off Piezo elements 11, 12, 13 assembled and extends over the one film-shaped ink fountain solution emulsion 14 covered axial length of the roller 4th

Die Funktion der Ultraschallquelle 8 ist folgende:The function of the ultrasound source 8 is as follows:

Eine während des aufeinander Abrollens der Walzen 4 und 5 und z. B. durch das Überrollen eines Zylinderkanals 15 des Druckformzylinders 2 verursachter Stoß kann zu einer streifenförmigen und parallel zur Kontaktlinie 9 verlaufenden Emulsionsstörung 16 innerhalb der ansonsten ungestörten Emulsion 14 führen. Beim Eintritt der Walze 4 in den Zylinderkanal 15 verringern sich schlagartig die Pressung und der Schlupf zwischen den Walzen 4 und 5 im Bereich der Kontaktlinie 9. Beim Austritt der Walze 4 aus dem Zylinderkanal 15 erhöhen sich die Pressung und der Schlupf schlagartig wieder. Die Pressung und der Schlupf, d. h. das Umfangsoberflächengeschwindigkeitsverhältnis, zwischen den Walzen 4 und 5 sind das Emulgieren der Druckfarbe und des Feuchmittels auf der Walze 4 beeinflussende Größen, durch deren schlagartige Änderungen die Emulsionsstörung 16 hervorgerufen wird. Um die gestörte Emulsion 14 zu homogenisieren, so weit dies möglich ist, und die Auffälligkeit der Emulsionsstörung 15 im Druckbild zu verringern, wird mittels fokussierter Ultraschallwellen 16, 17, 18 der Ultraschallquelle 8 nicht nur die Emulsionsstörung 15, sondern die gesamte Filmoberfläche der Emulsion 14 im Laufe von deren Vorbeitransport an der Ultraschallquelle 8 behandelt. Durch die auftreffenden Ultraschallwellen 16, 17, 18 wird die Walze 4 und auf dieser die Emulsion 14 in Schwingungen versetzt, deren Frequenz im für Ultraschall typischen Bereich liegt. Dadurch wird erreicht, dass das Feuchtmittel und die Druckfarbe, welche im Bereich der Emulsionsstörung 15 durch den Stoß lokal stark demulgiert sind, schnell wieder emulgieren. Die Beseitigung der Emulsionsstörung 16 erfolgt noch bevor diese die Kontaktlinie 10 erreicht und auf die Druckform 3 übertragen werden kann. Durch eine entsprechende Einstellung der Ultraschallquelle 8 ist die Intensität der Ultraschallwellen 16, 17, 18 variierbar. In Abhängigkeit von der Einstellung der Intensität können verschiedene Emulgiergrade der Emulsion 14 auf der Walze 4 eingestellt werden. Neben der bereits beschriebenen und das Emulgieren verbessernden Wirkung der Ultraschallwellen 17, 18, 19 unmittelbar innerhalb jenes Umfangsbereiches 20 der Walze 4, in welchem die Ultraschallwellen 17, 18, 19 auftreffen, haben letztere auch eine Fernwirkung innerhalb des Walzenspaltes bzw. der Kontaktlinie 9 zwischen den Walzen 4 und 5. Die durch die Ultraschallwellen 16, 17, 18 in Mikroschwingungen relativ zur Walze 5 versetzte Walze 4 bewirkt regelmäßige Mikrostörungen der Emulsion 14. Die gewollt erzeugten und während des Druckens permanent hervorgerufenen "Mikrostörungen" überlagern die ungewollte und viel stärkere Emulsionsstörung 16, so dass diese im Druckbild kaum noch auffällt, falls es durch den Einsatz der Ultraschallquelle 8 nicht gelingen sollte, die Emulsionsstörung 16 vor deren Übertragung auf die Druckform 3 vollständig zu beseitigen.One during the rolling of the rollers 4 and 5 and z. B. by that Rolling over a cylinder channel 15 of the printing form cylinder 2 can cause a shock a strip-shaped emulsion disturbance 16 running parallel to the contact line 9 lead within the otherwise undisturbed emulsion 14. When the roller 4 enters the Cylinder channel 15 abruptly reduce the pressure and the slip between the Rollers 4 and 5 in the area of the contact line 9. When the roller 4 emerges from the Cylinder channel 15 the pressure and the slip suddenly increase again. The Squeeze and slip, d. H. the peripheral surface speed ratio, between the rollers 4 and 5 are the emulsification of the printing ink and the fountain solution on the roller 4 influencing variables, the sudden changes in the Emulsion disorder 16 is caused. To the disturbed emulsion 14 too homogenize as much as possible and the abnormality of the emulsion disorder 15 To reduce in the printed image, by means of focused ultrasonic waves 16, 17, 18 Ultrasound source 8 not only the emulsion disturbance 15, but the entire film surface the emulsion 14 treated in the course of their transport past the ultrasound source 8. Due to the incident ultrasonic waves 16, 17, 18, the roller 4 and on this the Emulsion 14 vibrated, the frequency of which is typical for ultrasound Area. This ensures that the dampening solution and the printing ink, which in the Area of the emulsion disturbance 15 are locally strongly demulsified, quickly emulsify again. The elimination of the emulsion disturbance 16 takes place even before this Contact line 10 reached and can be transferred to the printing form 3. By a corresponding setting of the ultrasound source 8 is the intensity of the Ultrasonic waves 16, 17, 18 variable. Depending on the intensity setting Different degrees of emulsification of the emulsion 14 can be set on the roller 4. In addition to the effect already described and improving the emulsification Ultrasonic waves 17, 18, 19 directly within that circumferential area 20 of the Roller 4, in which the ultrasonic waves 17, 18, 19 hit, the latter also have one Long-distance effect within the nip or the contact line 9 between the rollers 4 and 5. The ultrasonic waves 16, 17, 18 in micro-vibrations relative to the Roller 5 offset roller 4 causes regular micro-disturbances of the emulsion 14. Die intentionally generated and permanently evoked during printing "Micro disturbances" overlay the unwanted and much stronger emulsion disturbance 16, see above that this is hardly noticeable in the printed image if it is used by the Ultrasound source 8 should not succeed, the emulsion disorder 16 before its transmission to eliminate printing form 3 completely.

In der Figur 2 ist gezeigt, dass der Walze 4 ein diese in Schwingungen einer Ultraschall entsprechenden Frequenz versetzender weiterer Schwingungserreger 21 zugeordnet ist, der z. B. statt der Ultraschallquelle 8 eingeschaltet werden kann. Es ist ersichtlich, dass die Walze 4 in mehrteiliger Ausbildung aus einer Walzenachse 22 und einer mittels einer Gleitbuchse 23 drehbar und axial verschiebbar auf der Walzenachse 22 gelagerten Walzenhülse 24 besteht. Der als ein Piezo-Element ausgebildete Schwingungserreger 21 ist mit seiner einen Seite an der Walzenachse 22 abgestützt und kann auch an einem anderen gestellfesten Teil abgestützt sein. Mit seiner anderen Seite drückt der Schwingungserreger 21 auf eine Seitenfläche der Walzenhülse 24 und eine in diese Seitenfläche übergehende Seitenfläche der Gleitbuchse 23. Durch eine entsprechende Bestromung wird der Schwingungserreger 21 in eine Ultraschallschwingung versetzt, welche der Schwingungserreger 21 über seine an der Walzenhülse 24 anliegende Seite auf die Walzenhülse 24 überträgt, so dass dadurch dieser Mikroschwingungen in Axialrichtungen der Walze 4 mit einer Ultraschall entsprechenden Frequenz aufgezwungen werden. Durch diese axiale Mikroschwingungen verbessert sich das Emulgierverhalten der Emulsion 14 nicht nur im Bereich der Emulsionsstörung 16, sondern auf der gesamten Umfangsoberfläche der Walzenhülse 24. Es kann vorgesehen sein, dass zusätzlich zur Walze 4 eine weitere Walze, vorzugsweise eine weitere Farbauftragswalze, oder weitere Walzen, vorzugsweise weitere Farbauftragswalzen, des Farbwerks 6 mit einem dem Schwingungserreger 21 konstruktiv und funktionell entsprechenden Schwingungserreger ausgerüstet ist bzw. sind. Ebenso kann eine Feuchtauftragswalze des bereits erwähnten Feuchtwerkes mit einem dem Schwingungserreger 21 entsprechenden Schwingungserreger ausgerüstet sein. Durch den Einsatz des zwischen der Walzenachse 22 und der Walzenhülse 24 angeordneten Schwingungserregers 21 der Walze 4 ist es möglich, die Gesamtanzahl der Walzen des Farbwerkes 6 im Vergleich zu einem konventionellen Farbwerk, welches um ein gutes Emulgieren zu erreichen, eine vergleichsweise große Anzahl von Walzen benötigt, zu reduzieren und das Farbwerk 6 als ein sogenanntes Kurzfarbwerk auszubilden. FIG. 2 shows that the roller 4 vibrates in an ultrasound is assigned to the corresponding frequency offset further vibration exciter 21, the z. B. can be switched on instead of the ultrasound source 8. It can be seen that the Roller 4 in a multi-part design from a roller axis 22 and one by means of a Sliding bush 23 rotatably and axially displaceably mounted on the roller axis 22 Roller sleeve 24 is made. The vibration exciter 21 designed as a piezo element is supported on one side on the roller axis 22 and can also on another part fixed to the frame. The vibration exciter presses with its other side 21 on a side surface of the roller sleeve 24 and a transition into this side surface Side surface of the sliding bushing 23 Vibration exciter 21 set in an ultrasonic vibration, which the Vibration exciter 21 on its side against the roller sleeve 24 on the Roller sleeve 24 transmits, so that this micro vibrations in axial directions the roller 4 can be forced with a frequency corresponding to ultrasound. By this axial micro-vibrations improves the emulsifying behavior of the emulsion 14 not only in the area of the emulsion disorder 16, but throughout Circumferential surface of the roller sleeve 24. It can be provided that in addition to Roller 4 another roller, preferably another inking roller, or more Rollers, preferably further inking rollers, the inking unit 6 with a Vibration exciter 21 structurally and functionally corresponding vibration exciter is or are equipped. A dampening roller of the type already mentioned can also be used Dampening unit with a vibration exciter corresponding to the vibration exciter 21 be equipped. By using the between the roller axis 22 and Roller sleeve 24 arranged vibration exciter 21 of the roller 4, it is possible Total number of rollers of the inking unit 6 compared to a conventional one Inking unit, which is comparatively large to achieve good emulsification Number of rollers required to reduce and the inking unit 6 as a so-called Train short inking unit.
