Description

Die Erfindung betrifft ein Verfahren zum Erzeugen von Spot-Lackierungen auf Bedruckstoffen in großformatigen Druckmaschinen, bei dem durch Aufbringen einer Farbschicht ein Druckbild auf dem Bedruckstoff erzeugt wird.The invention relates to a method for producing spot coatings on substrates in large-format printing machines, in which a printed image is applied by applying a layer of color the substrate is generated.

Zum Erzeugen von Spot-Lackierungen auf den Oberflächen von Bedruckstoffen ist es üblich, eigens dafür kopierte Druckplatten zu verwenden, die mit partiellen Aussparungen versehen sind. Im Fachbuch "Offsetdrucktechnik", 9. Auflage 1995, Seite 11/43 von Helmut Teschner wird diese Lösung vorgestellt. Dieser Weg versagt aber bei großformatigen Offsetdruckmaschinen, da Lackplatten mit derartigen Abmaßen nicht in befriedigender Qualität herstellbar sind.To create spot varnishes on the surfaces of substrates, it is common to to use specially copied printing plates with partial cutouts are. In the specialist book "Offsetdrucktechnik", 9th edition 1995, page 11/43 by Helmut Teschner presented this solution. This path fails with large format offset presses, however Lacquered panels with such dimensions cannot be produced in satisfactory quality.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des 1. und des 12. Anspruchs gelöst.According to the invention the object is solved by the features of the first and the twelfth claim.

Die Erfindung hat den Vorteil, dass nunmehr mit nur einer einzigen Lackplatte ohne partielle Aussparungen unterschiedliche Glanzgrade erzielt werden. Damit können die Herstellungskosten der Lackplatten extrem gesenkt werden. Die Lackplatte kann für mehrere Druckaufträge verwendet werden, was eine Verkürzung der Rüstzeiten nach sich zieht. Des weiteren ist nur eine Lackiereinheit bzw. ein Lackturm erforderlich.The invention has the advantage that now with only a single lacquer plate without partial Different gloss levels can be achieved. This can reduce the manufacturing costs of the lacquer plates can be extremely lowered. The varnish plate can be used for multiple print jobs become, which leads to a reduction in set-up times. Furthermore, there is only one Painting unit or a coating tower required.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Die dazugehörige Zeichnung zeigt eine großformatige Bogenoffsetdruckmaschine in Reihenbauweise.The invention will be explained in more detail using an exemplary embodiment. The Associated Drawing shows a large format sheetfed offset printing machine in a row.

Wie aus der Figur ersichtlich, besteht diese Bogenoffsetdruckmaschine aus mehreren, in Reihe angeordneten Druckwerken 31 bis 34. Im Ausführungsbeispiel sind beispielhaft vier Druckwerke 31 bis 34 dargestellt, wobei zur Durchführung des erfindungsgemäßen Verfahrens mindestens zwei Druckwerke erforderlich sind.As can be seen from the figure, this sheetfed offset printing press consists of several, in series arranged printing units 31 to 34. In the exemplary embodiment, four printing units are exemplary 31 to 34, wherein at least to carry out the method according to the invention two printing units are required.

Den Druckwerken 31 bis 34 ist ein Anleger 1 vorgeordnet. Der Aufbau und die Funktion des Anlegers 1 sind bekannt, so dass hier nicht näher darauf eingegangen werden muß. Die Druckwerke 31 bis 34 bestehen aus je einem Gegendruckzylinder 21 bis 24, je einem Plattenzylinder 5 und je einem Gummizylinder 6 (Plattenzylinder 5 und Gummituchzylinder 6 sind in der Figur nur im Druckwerk 31 bezeichnet). Die Bogenlaufrichtung ist durch einen Pfeil gekennzeichnet. Erkennbar sind weiterhin die von je zwei Gegendruckzylindern 21 bis 25 eingeschlossenen Bogenführungszylinder 71 bis 74, die bei einer im Schön- und Widerdruck einsetzbaren Druckmaschine auch als Wendetrommel ausgebildet sein können. Gegendruckzylinder 21 bis 24 und Bogenführungszylinder 71 bis 74 sind bogenführende Zylinder mit doppelt-großem Durchmesser. Die zu jedem Druckwerk 31 bis 34 gehörenden Farb- und Feuchtwerke sind hier nicht dargestellt.An feeder 1 is arranged upstream of the printing units 31 to 34. The structure and function of the Investors 1 are known, so that there is no need to go into them here. The printing units 31 to 34 each consist of an impression cylinder 21 to 24, each a plate cylinder 5 and each a blanket cylinder 6 (plate cylinder 5 and blanket cylinder 6 are only in the figure referred to in the printing unit 31). The direction of sheet travel is indicated by an arrow. recognizable are still the sheet guiding cylinders enclosed by two impression cylinders 21 to 25 71 to 74, for a printing machine that can be used in face and reverse printing can also be designed as a turning drum. Impression cylinders 21 to 24 and sheet guide cylinders 71 to 74 are double cylinders with a large diameter. The inking and dampening units belonging to each printing unit 31 to 34 are not shown here.

Die hier gezeigten Druckwerke 31 und 32 sind zum Verdrucken eines Farbsystems vorgesehen, das Farben mit strahlungstrocknenden - in der Regel UV-trocknende - Bestandteilen enthält. Die Druckwerke 33 und 34 sind zum Verdrucken von Farben vorgesehen, die für den Offsetdruck typisch sind.The printing units 31 and 32 shown here are provided for printing a color system, that contains paints with radiation-drying - usually UV-drying - components. The Printing units 33 and 34 are provided for printing colors, which are used for offset printing are typical.

Im Ausführungsbeispiel ist dem Druckwerk 32 ein Trockner 111 zugeordnet. Diese Trockner 111 ist nach dem zu trocknenden Farbsystem gewählt, so dass an dieser Stelle ein UV-Trockner eingesetzt wird.In the exemplary embodiment, a dryer 111 is assigned to the printing unit 32. This dryer 111 is selected according to the color system to be dried, so that a UV dryer is used at this point becomes.

In Bogenlaufrichtung nach den Druckwerken 31 bis 34 ist ein Lackturm 4 angeordnet. Dieser besteht aus dem Gegendruckzylinder 25, dem ein Lackformzylinder 8 zugeordnet ist. Auf dem Lackformzylinder 8 ist eine Lackplatte 81 aufgespannt. Der Lackturm 8 dient zum Überziehen des Druckbildes mit einer Lackschicht, die hier ebenfalls strahlungstrocknend ist.A coating tower 4 is arranged in the sheet running direction after the printing units 31 to 34. This consists of the impression cylinder 25 to which a coating cylinder 8 is assigned. On the Lacquer form cylinder 8, a lacquer plate 81 is stretched. The coating tower 8 is used for coating of the printed image with a lacquer layer, which is also radiation drying here.

Dem Lackformzylinder 8 bzw. der Lackplatte 81 ist hier eine Rasterwalze 9 zugeordnet. Zur Lackversorgung dieser Rasterwalze 8 ist eine Kammerrakel 10 angestellt. Dem Lackturm 4 ist weiterhin ein Trockner 112 zugeordnet.An anilox roller 9 is assigned to the coating forme cylinder 8 or the coating plate 81. to A chamber doctor blade 10 is employed to supply the lacquer to this anilox roller 8. The lacquer tower 4 is still assigned a dryer 112.

Nach dem Lackturm 4 ist eine Auslage 12 vorgesehen. Der Aufbau und die Funktion der Auslage 12 sind bekannt, so dass hier nicht näher darauf eingegangen wird.A display 12 is provided after the coating tower 4. The structure and function of the display 12 are known, so that they are not discussed in more detail here.

Mit dieser Einrichtung wird folgendes erfindungsgemäße Verfahren realisiert:The following inventive method is implemented with this device:

Der im Anleger 1 bereitgestellte Druckbogen wird von hier nicht näher beschriebenen Einrichtungen gefaßt und auf den Bogenweg gegeben. In den Druckwerken 31 bis 32 wird über den Gummituchzylinder 6 die Farbe eines Farbsystems aufgetragen, das anteilig eine unter Strahlung (im Ausführungsbeispiel unter ultravioletter Strahlung) härtende Farbe enthält. Derartige Farben werden als Hybridfarben bezeichnet. The printed sheet provided in the feeder 1 is used by facilities which are not described in more detail here caught and put on the archway. In the printing units 31 to 32, the Blanket cylinder 6 applied the color of a color system that proportionately under radiation (in the exemplary embodiment under ultraviolet radiation) contains hardening paint. Such colors are called hybrid colors.

Unter Farbsysteme werden hier die Farben zusammengefaßt, die im wesentlichen gleiche Verarbeitungseigenschaften aufweisen.The colors are summarized here under color systems, which have essentially the same processing properties exhibit.

Anschließend erfolgt das Trocknen dieser Farbschicht durch den Trockner 111, bevor der Druckbogen den folgenden Druckwerken 33 und 34 übergeben wird. Hier wird der Druckbogen mit den Farben eines Farbsystems bedruckt, das aus Farben besteht, die für den Offsetdruck typisch sind.This ink layer is then dried by dryer 111 before the printed sheet the following printing units 33 and 34 is handed over. Here is the printed sheet with printed on the colors of a color system that consists of colors that are typical for offset printing are.

Abschließend wird im Lackturm 4 durch die Lackplatte 81 ganzflächig Lack aufgetragen. Dieser Lack hat die Eigenschaft, dass er mit den Farbsystemen unterschiedlich physikalisch und/oder chemisch zusammenwirkt und dadurch den Glanzgrad der Farbschicht divergierend beeinflußt. Im Ausführungsbeispiel wird ein farbloser Lack verwendet, der ebenso wie die Hybridfarben unter UV-Licht aushärtet. Im Anschluß daran erfolgt die Trocknung der Lackschicht durch den Trockner 112.Finally, paint is applied over the entire area in the paint tower 4 through the paint plate 81. This Lacquer has the property that it is different with the color systems physically and / or chemically interacts and thereby affects the gloss level of the color layer diverging. In the exemplary embodiment, a colorless lacquer is used, which, like the hybrid colors, is below UV light cures. The lacquer layer is then dried by the Dryer 112.

Eine der möglichen Voraussetzung für den Eintritt des oben genannten Effektes ist, dass die Farbsysteme hinsichtlich ihrer Lack-Resorptionsfähigkeit voneinander abweichen. Dabei ist der Glanzgrad umgekehrt proportional zur Resorptionsfähigkeit des Farbsystems zum Lack, wobei bei Farbschichten mit Farbsystemen geringerer Resorptionsfähigkeit mehr Lack an deren Oberfläche verbleibt und bei Farbschichten aus Farbsystemen höherer Resorptionsfähigkeit ein höherer Anteil von der Farbschicht aufgenommen wird. Die glanzbestimmenden Bestandteile des Lackes werden von der Farbschicht aufgenommen.One of the possible conditions for the above effect to occur is that the Color systems differ from each other with regard to their paint absorption capacity. Here is the Degree of gloss is inversely proportional to the absorption capacity of the color system for the paint, whereby in the case of color layers with color systems with lower absorption capacity, more lacquer on their surface remains and with color layers from color systems of higher absorption capacity a higher one Share of the color layer is absorbed. The gloss determining components of the Lacquer is absorbed by the paint layer.

Die Erfindung beschränkt sich aber nicht ausschließlich auf die oben beschriebenen Unterschiede in der Resorptionsfähigkeit der Lackschicht. Es werden vielmehr alle Farbsysteme erfasst, die hinsichtlich des Zusammenwirkens mit der Lackschicht deren Glanzgrad bzw. Glanzwirkung spezifisch verändern. Dabei ist es nicht erforderlich, dass nach dem Bedrucken des Druckbogens bzw. des Bedruckstoffs eine Trocknung und/oder Härtung durch Energieeintrag erfolgt. Auch andere verfahrenstechnische Behandlungen der Farbschichten und/oder der Lackschichten sind möglich, um das physikalische und/oder chemische Zusammenwirken zum Erzielen der divergierenden Glanzgrade der finalen Lackschicht zu erzielen.However, the invention is not limited solely to the differences described above in the absorption capacity of the paint layer. Rather, all color systems are recorded that with regard to the interaction with the lacquer layer, its degree of gloss or gloss effect is specific change. It is not necessary that after printing on the printed sheet or the printing material is dried and / or hardened by energy input. Also other procedural treatments of the paint layers and / or the paint layers are possible to achieve the physical and / or chemical interaction to achieve the divergent To achieve gloss levels of the final paint layer.

In einer anderen Ausführungsform der Erfindung kann auf eine verfahrenstechnische Behandlung ganz oder teilweise verzichtet werden. Durch die Wahl der geeigneten Farbsysteme und des dazu korrespondierenden Lackes werden die oben genannten Effekte ebenfalls erreicht.
