Description

Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Erzeugen unterschiedlicher Glanzgrade auf Bedruckstoffen in Druckmaschinen, bei denen durch Aufbringen einer Farbschicht ein Druckbild auf dem Bedruckstoff erzeugt wird.The invention relates to a method and a device for producing different levels of gloss on printing substrates in printing machines, in which a printed image is produced on the printing substrate by applying a color layer.

Zum Erzeugen unterschiedlicher Glanzgrade auf den Oberflächen von Bedruckstoffen ist es üblich, eigens dafür kopierte Druckplatten als Lackplatten zu verwenden. Diese sind die mit partiellen Aussparungen versehen. In dem Fachbuch " Offsetdrucktechnik" von Helmut Teschner, 9. Auflage 1995, Seite 11/43 ist diese Verfahrensweise vorgestellt worden. Dazu wird ausgeführt, dass diese Technik dort ihre Grenzen hat, wo für besonders prägnante Glanzwirkungen einzelner Bereiche partiell stärkeres Überdrucken erforderlich wäre.To produce different degrees of gloss on the surfaces of printing materials, it is customary to use specially copied printing plates as coating plates. These are the ones with partial recesses. In the textbook " Offsetdrucktechnik "by Helmut Teschner, 9th edition 1995, page 11/43 this procedure has been presented. In addition it is stated that this technology has its limits there, where partially more overprinting would be required for particularly significant gloss effects of individual areas.

Von Nachteil ist auch die aufwendige Herstellung der Lackplatten. Soll eine mehrstufige Glanzwirkung auf einem Druckbild erzielt werden, so sind mehrere Lackplatten in mehreren Lackeinheiten erforderlich, was einen erheblichen Aufwand darstellt.Another disadvantage is the costly production of the paint plates. If a multi-level gloss effect is to be achieved on a printed image, then several paint plates in several paint units are required, which is a considerable expense.

Die Aufgabe der Erfindung besteht darin, ein Verfahren zum Erzeugen unterschiedlicher Glanzgrade auf Bedruckstoffen zu entwickeln, das mit nur einem Lackturm bzw. einer Lackiereinheit realisierbar und ohne eine speziell angefertigte Lackplatte durchführbar ist.The object of the invention is to develop a method for producing different degrees of gloss on printing substrates, which can be realized with only one coating tower or a coating unit and without a specially prepared coating plate feasible.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des unabhängigen 1., 2. und 13. Anspruchs gelöst. Die Erfindung wird in den Unteransprüchen ausgestaltet.According to the invention the object is achieved by the features of the independent 1st, 2nd and 13th claim. The invention is embodied in the subclaims.

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 coating plate without partial recesses different gloss levels can be achieved. Thus, the manufacturing cost of the paint plates can be extremely reduced. The varnish plate can be used for several print jobs, resulting in a shortening of set-up times. Furthermore, only one painting unit or one coating tower is required.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Die dazugehörige Zeichnung zeigt eine Bogenoffsetdruckmaschine in Reihenbauweise.The invention will be explained in more detail using an exemplary embodiment. The accompanying drawing shows a sheet-fed offset printing machine in a row construction.

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 sheet-fed offset printing machine consists of several, arranged in series printing units 31 to 34. In the exemplary embodiment are exemplary four printing units 31 to 34, wherein for carrying out the method according to the invention at least 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.The printing units 31 to 34, a feeder 1 is arranged upstream. The structure and function of the investor 1 are known, so that it need not be discussed in detail here. The printing units 31 to 34 each consist of a counter-pressure cylinder 21 to 24, one plate cylinder 5 and one blanket cylinder 6 (plate cylinder 5 and blanket cylinder 6 are indicated in the figure only in the printing unit 31). The sheet travel direction is indicated by an arrow. Recognizable are further enclosed by two counter-pressure cylinders 21 to 25 sheet guiding cylinder 71 to 74, which can also be designed as a turning drum at an insertable in perfecting printing press. Back-pressure cylinders 21 to 24 and sheet-guiding cylinders 71 to 74 are arc-guiding cylinders of double-large diameter. The colorant 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-trocknenden - 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 containing colors with radiation-drying - usually UV-drying - components. The printing units 33 and 34 are provided for printing in colors which are typical for offset printing.

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, the printing unit 32 is associated with a dryer 111. This dryer 111 is selected according to the color system to be dried, so that at this point a UV dryer is used.

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 .In the direction of sheet travel after the printing units 31 to 34, a coating tower 4 is arranged. This consists of the impression cylinder 25, which is associated with a paint-forming cylinder 8. On the paint form cylinder 8, a paint plate 81 is clamped. The coater tower 8 is used to coat 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.The paint form cylinder 8 and the paint plate 81 is assigned here an anilox roller 9. To paint supply this anilox roller 8 a chamber doctor blade 10 is employed. The coating tower 4 is further associated with 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.After the coating tower 4 a display 12 is provided. The structure and function of the display 12 are known, so that will not be discussed further here.

Mit dieser Einrichtung wird folgendes erfindungsgemäße Verfahren realisiert:With this device, the following inventive method is realized:

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 provided in the feeder 1 sheet is taken from here unspecified facilities and placed on the bow path. In the printing units 31 to 32, the color of a color system is applied via the blanket cylinder 6, which proportionally contains a curable color under radiation (in the exemplary embodiment under ultraviolet radiation). Such colors are referred to as hybrid colors.

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

Anschließend kann optional das Trocknen dieser Farbschicht durch den Trockner 111 erfolgen, bevor der Druckbogen den folgenden Druckwerken 33 und 34 übergeben wird. Hier wird der Druckbogen mit den Farben eines Farbsystems bedruckt, das aus anderen Farben besteht, wie zum Beispiel aus Farben, die für den Offsetdruck typisch sind.Subsequently, optionally, the drying of this ink layer by the dryer 111 take place before the sheet is passed to the following printing units 33 and 34. Here, the sheet is printed with the colors of a color system that consists of other colors, such as colors that are typical for offset printing.

Es ist aber auch möglich, das eines dieser Farbsysteme ein für Druckfarben typisches Bindemittel ist, wie zum Beispiel ein Firnis ist.But it is also possible that one of these color systems is a binder typical for printing inks, such as a varnish.

Anschließend 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 betreffenden 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.Subsequently, in the coating tower 4 paint is applied through the paint plate 81 over the entire surface. This lacquer has the property that it interacts physically and / or chemically differently with the color systems and thereby divergently influences the degree of gloss of the respective color layer. In the exemplary embodiment, a colorless lacquer is used, which cures as well as the hybrid colors under UV light. Subsequently, the drying of the paint layer by the dryer 112 takes place.

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 prerequisites for the occurrence of the above-mentioned effect is that the color systems deviate from each other in terms of their paint absorbability. In this case, the gloss level is inversely proportional to the absorption capacity of the paint system to the paint, with paint layers with paint systems lower resorption more paint remains on the surface and color layers of color systems higher resorption a higher proportion of the color layer is added. The gloss-determining constituents of the lacquer are absorbed by the color layer.

Ist auf der Oberfläche als Farbsystem ein Bindemittel aufgetragen, so wird der Lack nahezu vollständig von diesem aufgenommen. Das ist dort sinnvoll, wo zum Beispiel beim Bedrucken von Verpackungszuschnitten die Klebelaschen frei von Lack gehalten werden müssen, da dieser den nachfolgend aufgetragenen Klebstoff abstößt.If a binder is applied to the surface as the paint system, the paint is almost completely absorbed by it. This is useful where, for example, when printing Packaging blanks the adhesive flaps must be kept free of paint, as this repels the subsequently applied adhesive.

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 exclusively to the above-described differences in the absorption capacity of the lacquer layer. Rather, all color systems are detected which specifically change their gloss level or gloss effect with respect to the interaction with the lacquer layer. It is not necessary that after printing the sheet or the substrate drying and / or curing by energy input takes place. Other procedural treatments of the color layers and / or the lacquer layers are possible in order to achieve the physical and / or chemical interaction to achieve the divergent gloss levels of the final lacquer 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.

In another embodiment of the invention can be dispensed with a procedural treatment wholly or partly. By choosing the appropriate color systems and the corresponding paint the above effects are also achieved.
