Description

Die Erfindung betrifft Druckformen für Druckverfahren, insbesondere für den Offsetdruck.The invention relates to printing plates for printing processes, in particular for offset printing.

Im Offsetdruck (Bogenoffset und Rollenoffset) wird eine Druckplatte aus Metall oder Kunststoff eingefärbt. Diese Druckplatte übergibt das Druckbild an ein Gummituch. Das Druckbild wird dann vom Gummituch auf den Bedruckstoff übergeben. Das Gummituch im Druckwerk einer Offsetdruckmaschine, die Druckplatte und auch der Bedruckstoff sind so auf den Zylindern aufgespannt, dass sie aufeinander abrollen.In offset printing (sheetfed offset and web offset), a printing plate made of metal or plastic is dyed. This printing plate transfers the printed image to a blanket. The printed image is then transferred from the blanket to the substrate. The blanket in the printing unit of an offset printing press, the printing plate and the substrate are clamped on the cylinders so that they roll on each other.

Drucktücher bzw. Druckformen mit maßstabilen Gewebeschichten, kompressiblen Schichten oder auch Metallträgern gibt es von verschiedenen Herstellern in den unterschiedlichsten Aufbauten.Printing blankets or printing forms with dimensionally stable fabric layers, compressible layers or metal substrates are available from various manufacturers in a wide variety of constructions.

So offenbart das Dokument US 2010/0307356 A1 ein Drucktuch in Form eines Drucktuchzylinders oder einer Drucktuchhülse, bestehend aus einer druckenden Schicht aus Polyurethan, einer hochrigiden Kernschicht sowie einer dazwischen angeordneten Überbrückungsschicht.This is how the document reveals US 2010/0307356 A1 a blanket in the form of a blanket cylinder or a blanket sleeve, consisting of a printing layer of polyurethane, a hochrigiden core layer and a bridging layer arranged therebetween.

In der EP 2 085 246 A1 wird ein Drucktuch mit einer druckenden Schicht aus Polyurethan und einer Kernschicht aus Nickel offenbart.In the EP 2 085 246 A1 A printing blanket is disclosed having a printing layer of polyurethane and a core layer of nickel.

Das Dokument US 2007/0277690 A1 offenbart eine Offsetdruckvorrichtung mit einer Drucktrommel, aufweisend ein Substrat, eine optionale intermediäre Schicht, eine elastomere Außenschicht sowie ein auf der elastomeren Schicht befindliches Trennmittel.The document US 2007/0277690 A1 discloses an offset printing apparatus having a printing drum comprising a substrate, an optional intermediate layer, an elastomeric outer layer, and a release agent disposed on the elastomeric layer.

Das Dokument US 3,276,947 offenbart ein Drucktuch, bestehend aus einer druckenden Schicht aus Polyurethan sowie einer weiteren elastomeren Schicht, welche mittels Faserschnüren verstärkt ist.The document US 3,276,947 discloses a blanket consisting of a printing layer of polyurethane and another elastomeric layer reinforced by fiber cords.

Trotzdem besteht weiterhin Bedarf nach weiteren Drucktüchern mit unterschiedlichen Eigenschaften hinsichtlich der Stabilität des Druckverhaltens etc.Nevertheless, there is still a need for more blankets with different properties with regard to the stability of the printing behavior, etc.

Aufgabe der vorliegenden Erfindung ist es, entsprechende Drucktücher für den Offsetdruck bereit zu stellen.Object of the present invention is to provide appropriate blankets for offset printing.

Gelöst wird die Aufgabe durch ein Drucktuch umfassend mindestens eine druckende Schicht aus Polyurethan, die trennbar mit mindestens einer steifen Schicht aus Polyethylenterephtalat verbunden ist, wobei das Drucktuch mindestens eine kompressible Schicht aufweist, die trennbar mit mindestens einer Schicht des Drucktuchs verbunden ist und aus Polyurethan, Polyethylen, Polypropylen, Polyvinylchlorid, Nitrilkautschuk, Butylkautschuk, Styrol-Butadien-Kautschuk Ethylen-Propylen-Dien-Kautschuk, Polystyrol, Silikon und Mischungen ausgewählt ist.The object is achieved by a printing blanket comprising at least one printing layer of polyurethane, which is separably connected to at least one rigid layer of polyethylene terephthalate, wherein the blanket has at least one compressible layer which is separably connected to at least one layer of the blanket and made of polyurethane, Polyethylene, polypropylene, polyvinyl chloride, nitrile rubber, butyl rubber, styrene-butadiene rubber, ethylene-propylene-diene rubber, polystyrene, silicone and mixtures.

Erfindungsgemäß wird ein Drucktuch verwendet, bei dem im Gegensatz zu den üblichen Gummitüchern die obere druckende Schicht aus Polyurethanausgewählt ist. Die erfindungsgemäß eingesetzten Materialien zeichnen sich unter anderem durch eine gute Waschbarkeit aus. Es ist im Vergleich zum Gummituch weniger Kraft beim Abwischen notwendig bzw. mit einem geringeren Verbrauch von Reinigungsmitteln kann eine saubere Oberfläche erzielt werden. Häufig können auch mildere Reinigungsmittel, beispielsweise Wasser oder Wasser mit Tensiden, statt der sonst üblichen Alkohole und Reinigungsbenzine eingesetzt werden. Da beim Reinigen weniger Angriffe auf die Oberfläche erfolgen, wird die Häufigkeit von Geisterbildern verringert.According to the invention, a printing blanket is used in which, unlike the usual blankets, the upper polyurethane printing layer is selected. The materials used according to the invention are characterized, inter alia, by good washability. It is compared to the blanket less force when wiping necessary or with a lower consumption of cleaning agents, a clean surface can be achieved. Often, milder detergents, for example water or water with surfactants, instead of the usual alcohols and cleaning spirits can be used. As there are fewer attacks on the surface during cleaning, the frequency of ghost images is reduced.

Geisterbilder entstehen typischerweise durch die irreversible Veränderung der Oberfläche eines Drucktuchs bei Änderungen von chemisch-physikalischen und mechanischen Eigenschaften.Ghosting typically results from the irreversible change in the surface of a blanket with changes in chemical-physical and mechanical properties.

In einer Ausführungsform lässt der Aufbau gemäß Anspruch 1 eine Trennung in die Komponenten "Unterbau" und "druckende Einheit" des Drucktuchs zu. Dadurch sind zusätzliche Kosteneinsparungen möglich, da bei Zerstörung bzw. Abnutzung entweder nur die "druckende Einheit" oder der "Unterbau" ersetzt werden müssen.In one embodiment, the structure according to claim 1 allows a separation into the components "substructure" and "printing unit" of the blanket. As a result, additional cost savings are possible because in case of destruction or wear either only the "printing unit" or the "substructure" must be replaced.

Der Druckprozess im Offsetdruck beinhaltet diverse Stufen, die den Druckpunkt gegenüber einem idealen Druckpunkt (punktförmiger Bildteil, der durch die Rasterung und Unterteilung in die Druckfarben entsteht) verändern:

  1. I. Die Übertragung der aufbereiteten Bildvorlage auf eine Druckplatte verändert die Größe eines Punktes.
  2. II. Die Übertragung des eingefärbten Druckpunktes / Bildpunktes von der Druckplatte zum Gummituch verändert die Punktgröße und auch die Geometrie des Druckpunktes.
  3. III. Die Übertragung des Druckpunktes vom Gummituch zum Bedruckstoff verändert die Größe und die Geometrie des Druckpunktes.
The printing process in offset printing involves various stages that change the pressure point from an ideal pressure point (dot-shaped image part, which results from the screening and subdivision into the printing inks):
  1. I. The transfer of the processed image template to a printing plate changes the size of a dot.
  2. II. The transfer of the inked dot / dot from the printing plate to the blanket changes the dot size and also the geometry of the printing dot.
  3. III. The transfer of the pressure point from the blanket to the substrate changes the size and the geometry of the pressure point.

Verändert sich die Größe des Druckpunktes im Druckprozess, spricht man vom "Punktzuwachs". Dieser ist nur abhängig von den Gegebenheiten der drei Übertragungsschritte (I. - III.) und sehr untergeordnet von der Druckgeschwindigkeit und der Druckzeit/Dauer des Druckjobs.If the size of the pressure point changes in the printing process, this is called "dot gain". This is only dependent on the conditions of the three transfer steps (I. - III.) And very much subordinate to the printing speed and the printing time / duration of the print job.

Die quantitative Veränderung des Druckpunktes, ist über den realen Rasterverlauf von 2% bis 98% nicht linear. Der Zusammenhang wird in Form der Druckkennlinie für die Druckmaschine und der Druckmaschinenkonfiguration wiedergegeben.The quantitative change of the pressure point is not linear over the real raster of 2% to 98%. The relationship is represented in the form of the printing characteristic for the printing machine and the printing press configuration.

Durch die Druckkennlinie können in der Druckvorstufe Maßnahmen ergriffen werden, die der Veränderung des Druckpunktes entgegenwirken. Dieser Prozess ist extrem zeitaufwendig und muss bei jeder Veränderung im Druckjob durchgeführt werden.Due to the pressure characteristic measures can be taken in the prepress stage, which counteract the change of the pressure point. This process is extremely time consuming and must be done every time you make a change in the print job.

Durch die erfindungsmäßige, polymere Druckschicht werden die Veränderungen in Übertragungsprozess signifikant reduziert. Druckmaschinenspezifische Eigenschaften können über die Schichten, Lagen und Komponenten berücksichtigt werden.The inventive, polymeric printing layer significantly reduces the changes in the transfer process. Printing press specific properties can be considered across the layers, layers and components.

Die Geometrieveränderung (Fachausdruck "Schieben des Druckpunktes") in den Übertragungsschritten I. bis III. sind neben weiteren Parametern durch das Zusammenspiel zwischen der Übertragungsoberfläche der Druckplatte und der Übertragungsoberfläche des Bedruckstoffs gekennzeichnet.The change in geometry (technical term "pushing the pressure point") in the transfer steps I. to III. are characterized, among other parameters, by the interaction between the transfer surface of the printing plate and the transfer surface of the printing substrate.

Dabei treten selbst bei optimaler Maschinenabstimmung Geometrieveränderungen des Druckpunktes auf. Der Druckpunkt kann in die Länge gezogen werden, kann bei geringer Größe nur zu einem Bruchteil oder nicht übertragen werden oder kann eine bizarre, schroffe Randstruktur aufweisen.At the same time, even with optimum machine tuning, geometric changes of the pressure point occur. The pressure point can be elongated, can be transferred at a fraction or not at a small size, or can have a bizarre, rugged edge structure.

Überraschenderweise haben sich bei Untersuchungen von bisher unüblichen und nicht verwendeten Polymeren und im Besonderen, wenn eine gezielten Oberflächenstrukturierung durchgeführt wurde, gezeigt, dass sehr deutliche Effekte reproduzierbar eingestellt werden können, die den "Punktzuwachs", das "Schieben" und die unregelmäßige "Randstruktur" reduzieren.Surprisingly, studies of hitherto unusual and unused polymers and, in particular, when a targeted surface structuring has been carried out, have shown that it is possible to reproducibly and very reproducibly produce very pronounced effects which increase the "dot gain", the "push" and the irregular "edge structure". to reduce.

Um eine weitere Optimierung zur erreichen, hat sich gezeigt, dass ein mehrlagiger Aufbau aus steifen, aus flexiblen, aus kompressiblen Schichten oder Kombinationen daraus, Abhilfe schafft.In order to achieve further optimization, it has been found that a multilayer construction of rigid, flexible, compressible layers or combinations thereof, remedy.

Es ist gelungen, Aufbauten zu realisieren, die in einem weiten Bereich hervorragende Ergebnisse unabhängig vom Maschinentyp liefern.It has been possible to realize superstructures that deliver outstanding results in a wide range regardless of the machine type.

Particularly suitable as rigid layers are dimensionally stable films, for example made of PET (modulus of elasticity 1.0 to 5.0 kN / mm 2 ), aluminum (modulus of elasticity 65 to 75 kN / mm 2 ), steel (modulus of elasticity 65 to 75 kN / mm 2 ) , Brass or copper (modulus of elasticity 65 to 165 kN / mm 2 ) or combinations thereof, such as aluminum-PET.

Die Schichten, die trennbar verbunden sind, können durch einen Haftkleber oder durch die gemeinsame Montage auf einem Druckzylinder miteinander verbunden sein.The layers, which are separably joined, may be bonded together by pressure-sensitive adhesive or by joint assembly on a printing cylinder.

Eine weitere Ausführungsform ist ein Drucktuch umfassend zusätzlich eine drucksensitive Kleberschicht oder eine steife Schicht.Another embodiment is a blanket comprising in addition a pressure-sensitive adhesive layer or a rigid layer.

Alle diese Ausführungsformen können zusätzlich eine oder mehrere drucksensitive Kleberschichten und eine oder mehrere steife Schichten umfassen. Es können auch eine oder mehrere Schichten ausgewählt aus flexiblen Schichten, kompressiblen Schichten und Gewebeschichten vorhanden sein. Diese können auch zusätzlich noch eine drucksensitive Kleberschicht aufweisen.All of these embodiments may additionally include one or more pressure-sensitive adhesive layers and one or more rigid layers. There may also be one or more layers selected from flexible layers, compressible layers, and fabric layers. These may also additionally have a pressure-sensitive adhesive layer.

Gegenstand der Erfindung ist auch die Verwendung eines Drucktuchs mit den Merkmalen der Erfindung als Drucktuch im Offsetdruck.The invention also provides the use of a printing blanket with the features of the invention as blanket in offset printing.

In einer Ausführungsform wird erfindungsgemäß auf Gewebeschichten verzichtet. Wenn Gewebeschichten vorhanden sind, sind sie nicht für die Maßstabilität erforderlich, sondern können als weiche und flexible Schicht vorhanden sein. Dabei werden bevorzugt chemisch-stabile Gewebe verwendet, die nicht quellen oder ausfasern.In one embodiment, according to the invention, tissue layers are dispensed with. When fabric layers are present, they are not required for dimensional stability, but may exist as a soft and flexible layer. In this case, preference is given to using chemically stable fabrics which do not swell or fray.

Erfindungsgemäß wird keine vulkanisierte Gummisorte eingesetzt, so dass auf Schleifprozesse verzichtet werden kann. Thermoplaste wie Polyurethan können im Kalanderverfahren oder mittels Beschichtung auf geeigneten Oberflächen aufgebracht werden. Dünne Beschichtungen bilden bei geeigneten Rezepturen gleichmäßige Oberflächen aus. Die realisierbaren Oberflächen sind dadurch gezielt und in engen Toleranzen bezüglich der Gesamtdicke herstellbar. Die druckende Schicht kann mit einer sehr glatten, einer leicht aufgerauten oder einer strukturierten Oberfläche ausgerichtet sein.According to the invention, no vulcanized rubber grade is used so that grinding processes can be dispensed with. Thermoplastics such as polyurethane can be applied by calendering or by coating on suitable surfaces. Thin coatings form uniform surfaces with suitable formulations. The realizable surfaces are thus produced selectively and in close tolerances with respect to the total thickness. The printing layer may be aligned with a very smooth, slightly roughened or textured surface.

Im Gegensatz zu den bisher eingesetzten duroplastischen Gummioberflächen ist das erfindungsgemäße Verfahren schneller und kostengünstiger, da auf das Schleifen verzichtet werden kann.In contrast to the thermoset rubber surfaces used hitherto, the method according to the invention is faster and more cost-effective, since grinding can be dispensed with.

Sind anlagenspezifische Modifikationen notwendig (eine gezielte Verbesserung im unteren Rasterbereich, z.B. 2% bis 40%) kann es notwendig sein, einen flexiblen oder auch kompressiblen Aufbau, als Komponente oder Lage unter der druckenden Schicht, zu verwenden.If plant-specific modifications are necessary (a targeted improvement in the lower grid area, eg 2% to 40%) it may be necessary to use a flexible or compressible structure, as a component or layer under the printing layer to use.

Durch die Unterteilung in Komponenten können Druckmaschinen unterschiedlicher Bauart bestückt werden. Maschinentypische Einspann- und Befestigungssysteme können berücksichtigt werden, die zunächst nicht mit dem Übertrag des Druckpunktes im Zusammenhang stehen.By dividing into components printing presses of different types can be equipped. Machine-specific clamping and fastening systems can be taken into account, which are initially not related to the transfer of the pressure point.

Überraschenderweise zeigte sich, dass es nicht zwangsläufig notwendig ist, die steifen, die flexiblen oder die kompressiblen Schichten dauerhaft mit einander zu verbinden (z.B. durch Verkleben, Verschweißen, Koextrudieren).Surprisingly, it has been found that it is not necessarily necessary to permanently bond the rigid, flexible or compressible layers together (e.g., by gluing, welding, co-extruding).

Ein erheblicher Teil des unteren Teils (Zylinderpackung) kann über die Standzeit der polymeren Übertragungsschicht hinaus weiter verwendet werden und kann dauerhaft haftend oder wiederholt mit eingespannt, auf dem Zylinder verbleiben.A significant portion of the lower part (cylinder packing) can continue to be used beyond the service life of the polymeric transfer layer and can be permanently adhered or repeatedly clamped to remain on the cylinder.

Daher ist es notwendig im Fall der vorliegenden Erfindung in einen Grenzfall aus einer Komponente oder im häufigen Fall von zwei oder mehrerer Komponenten zu unterscheiden, die im gesamten Verbund als äußerste Schicht die druckende Schicht tragen.Therefore, in the case of the present invention, it is necessary to distinguish into a limiting case of one component or, in the frequent case of two or more components, which carry the printing layer as the outermost layer in the entire composite.

Die oberste Komponente enthält mindestens eine Schicht - die polymere Übertragungsschicht - oder zusätzlich mehrere Schichten aus flexiblen, kompressiblen und steifen Materialien. Mindestens zwei Packungen, bzw. mechanisch zunächst getrennte Lagen, werden benötigt, wenn ein ansonsten biegesteifer Verbund mit zwei steifen Schichten entsteht (Sandwich- oder auch Wellkarton-Effekt). Es ist in diesen Fällen sinnvoll, die Fertigstellung der gesamten Schichtabfolge in der Druckmaschine vor zu nehmen. Auch hier können die Schichten und Lagen selbstklebend mit einander verbunden werden oder mit geeigneten Vorrichtungen auf einander gespannt werden.The uppermost component contains at least one layer - the polymeric transfer layer - or in addition several layers of flexible, compressible and rigid materials. At least two packages or mechanically separate layers are required if an otherwise rigid composite with two rigid layers is produced (sandwich or corrugated cardboard effect). It makes sense in these cases to undertake the completion of the entire sequence of layers in the printing press. Again, the layers and layers can be self-adhesive connected to each other or stretched with suitable devices on each other.

Es ist möglich, dass die druckende Einheit direkt, insbesondere durch Kleber, auf den Druckzylinder aufgebracht wird. Dies erfolgt vollflächig oder durch partiell aufgeklebte Stücke.It is possible that the printing unit is applied directly, in particular by adhesive, to the printing cylinder. This is done over the entire surface or by partially glued pieces.

Erfolgt die Verklebung auf einer zuvor eingespannten oder verklebten Komponente, die sich auf dem Zylinder befindet, kann es von Vorteil sein, dass die obere Schicht der Komponente ein steifer Kunststoff ist. Dieser Kunststoff kann wiederum Oberflächenmerkmale aufweisen, die eine Beschädigung durch mechanische Einflüsse erschwert, die leicht zu reinigen ist, die reduzierte oder erhöhte Release-Eigenschaften zur Optimierung der Klebeeigenschaften ermöglicht.If the bonding takes place on a previously clamped or glued component which is located on the cylinder, it may be advantageous for the upper layer of the component to be a rigid plastic. This plastic, in turn, may have surface features that make it difficult to damage due to mechanical influences that are easy to clean, allowing for reduced or increased release properties to optimize adhesive properties.

Im Fall des Aufklebens auf einen Untergrund, der nicht direkt aus der metallischen oder keramischen unmittelbaren Zylinderoberfläche besteht, wird der dadurch erzielte Verbund als eine Komponente aus mehreren Lagen aufgefasst. Durch die schichtweise Montage wird im Einzelfall ein sonst sehr biegesteifer Verbund spannungsfrei um einen Zylinder geführt. Dennoch bleibt die obere Komponente austauschbar, der stabile Verbund wird gezielt getrennt. Das Bekleben der Packung mit dem druckenden Polymer, kann partiell oder vollflächig erfolgen.In the case of adhering to a substrate which does not consist directly of the metallic or ceramic immediate cylindrical surface, the composite obtained thereby is considered as a multi-layered component. Due to the layered assembly an otherwise very rigid composite is guided stress-free around a cylinder in individual cases. Nevertheless, the upper component remains interchangeable, the stable composite is selectively separated. The sticking of the pack with the printing polymer can be partial or full-surface.

Die Erfindung wird durch die folgende Figur erläutert.The invention is illustrated by the following figure.

Figur 1 zeigt einen dreischichtigen Aufbau eines Drucktuchs mit einer druckenden Schicht 1 aus Polyurethan, einer von der druckenden Schicht 1 trennbaren und darunter angeordneten steifen Schicht 2 aus Polyethylentherephthalat sowie einer kompressiblen Schicht 3, die die unterste Schicht bildet.1 shows a three-layered construction of a printing blanket with a printing layer 1 made of polyurethane, a separable from the printing layer 1 and arranged underneath a rigid layer 2 of polyethylene terephthalate and a compressible layer 3, which forms the lowermost layer.

Beispiel: Example :

Auf eine Trägerschicht aus Polyethylenterephthalat (Mylar® A 350 µm, DuPont) wird mit einem geeigneten Bindersystem (Henkel Liofol® UR 2780) eine Polyurethanfolie der Dicke 500 µm (Swissfilm® 4250, SwissChem AG) aufgebracht. Die Polyethylenterephthalat-Seite dieses Laminates wird anschließend mit einem Polyethylen-Schaum der Dicke 1080 µm (TME® S 0400, Sekisui Alveo GMBH) verklebt, dies ebenfalls mit einem zur Verklebung geeignetem Bindersystem (Henkel Liofol® UR 2780). Der Gesamtverbund ergibt eine Dicke von 1,95 mm. Die vorderseitige Polyurethanfolie stellt die druckende Seite dar und dient zur Übertragung der Druckfarbe.On a backing layer of polyethylene terephthalate (Mylar ® A 350 .mu.m, DuPont) is mixed with a suitable binder system (Henkel Liofol UR 2780 ®), a polyurethane film of thickness 500 microns (Swiss film ® 4250, SwissChem AG) was applied. The polyethylene terephthalate side of this laminate is then reacted with a polyethylene foam having a thickness of 1080 microns (TME ® S 0400, Sekisui Alveo GMBH) glued, this also with a suitable binder system for bonding (Henkel Liofol UR 2780 ®). The total composite results in a thickness of 1.95 mm. The front-side polyurethane film represents the printing side and serves to transfer the printing ink.
