Abstract

Substances with a low surface energy are added to the oil-based matt varnish or printing ink used in a printing process which involves printing or coating in succession with oil-based printing ink, matt varnish or ink (on parts of the printed surface) and transparent gloss varnish (over the whole printed surface). A printing process in which print material, in passing through a printing machine (2) with several printing groups (6, 8, 10, 12) followed by a varnishing group (14), is first printed with an oil-based printing ink (I) in at least one of the groups (6, 8, 10), then coated (in group 12) on parts of the printed surface with an oil-based matt varnish or printed with matt ink (II) (containing a dulling agent), and finally coated over the entire printed surface with a transparent gloss varnish (III) (in group 14). In this process, the matt varnish or matt ink (II) is modified by adding substance(s) (IV) with a low surface energy. An independent claim is also included for products printed on at least one side by this process, using oil-based offset printing ink.

Description

Die Erfindung betrifft ein Druckverfahren, insbesondere ein Bogenoffsetdruckverfahren, bei dem ein Bedruckstoff nach dem Bedrucken durch Spot-Lackierung mit transparenten Lacken oder Überdrucken mit einer Mattierungsmittel enthaltenden Farbe auf einem Teil der zuvor bedruckten Fläche mit einer matten Oberfläche und auf einem anderen Teil der bedruckten Fläche mit einer glänzenden Oberfläche versehen wird. Durch die unterschiedliche Oberflächenbeschaffenheit und den Kontrast zwischen benachbarten matten und glänzenden Teilflächen kann man zum Beispiel unterschiedliche Farben des Druckbildes stärker voneinander abheben, den matt lackierten Teilflächen ein samtiges Aussehen bzw. den glänzend lackierten Teilflächen ein spiegelndes, silbriges oder goldenes Aussehen verleihen oder andere ansprechende optische Effekte erzielen. Die Erfindung betrifft weiter ein mit einem Offsetdruckverfahren hergestelltes Druckerzeugnis.The invention relates to a printing method, in particular a sheet-fed offset printing method in which a substrate after printing by spot coating with transparent paints or overprinting with a matting agent-containing paint on a part of the previously printed area with a matte surface and on another part of the printed area provided with a glossy surface. Due to the different surface texture and the contrast between adjacent matte and glossy faces, for example, different colors of the printed image stand out from each other, give the matt lacquered faces a velvety appearance or the glossy painted faces a reflective, silvery or golden appearance or other appealing visual Achieve effects. The invention further relates to a printed product produced by an offset printing process.

Zur Herstellung von Druckerzeugnissen mit nebeneinander angeordnete matten und glänzenden Teilflächen ist es bereits bekannt, den Bedruckstoff zweimal nacheinander durch eine Offsetdruckmaschine laufen zu lassen. Dabei wird der Bedruckstoff im ersten Durchlauf in den Druckwerken der Druckmaschine mit den gewünschten Druckfarben bedruckt und in einem nachgeschalteten Lackwerk der Druckmaschine entweder im Bereich der späteren glänzenden Oberflächen mit einem Glanzlack oder aber im Bereich der späteren matten Oberflächen mit einem Mattlack beschichtet, während die jeweils anderen Bereiche ausgespart bleiben und erst während des zweiten Durchlaufs durch die Druckmaschine lackiert werden. Dieses Verfahren, bei dem der zweite Lackauftrag auf der bereits getrockneten Druckfarbe erfolgt, weist jedoch drei wesentliche Nachteile auf. Zum ersten sind zwei Durchläufe durch die Druckmaschine erforderlich, wodurch der Druck verteuert wird. Zum zweiten kann es bei den beiden Durchläufen zu Passerdifferenzen kommen, was im Druckbild an den Begrenzungen zwischen den matten bzw. glänzenden Teilflächen zu sichtbaren Überlappungen oder Zwischenräumen zwischen den beiden Arten von Oberflächen führen kann. Zum dritten werden sowohl zur Matt- und zur Glanzlackierung teuere Photopolymerplatten benötigt, da sich mit herkömmlichen Offsetdruckplatten einzelne Teilflächen des Bedruckstoffs nicht getrennt beschichten lassen.For the production of printed products with juxtaposed matte and glossy faces, it is already known to run the substrate twice in succession through an offset printing press. In this case, the substrate is printed in the first pass in the printing units of the printing press with the desired inks and coated in a downstream coating unit of the printing press either in the area of the later glossy surfaces with a gloss varnish or in the later matte surfaces with a matt varnish, while each remain spared other areas and painted only during the second pass through the printing press. However, this process, in which the second coating application takes place on the already dried printing ink, has three significant disadvantages. First, two passes through the press are required, making the print more expensive. Secondly, it can lead to Passerdifferenzen in the two passes, which can lead to visible overlaps or gaps between the two types of surfaces in the printed image at the boundaries between the matte or glossy faces. Thirdly, expensive photopolymer plates are required for both matt and gloss varnishing because individual partial surfaces of the printing substrate can not be coated separately with conventional offset printing plates.

Aus der DE 200 20 798 U1 ist bereits eine Einrichtung zum Erzeugen von Spotlackierungen auf Bedruckstoffen in einer großformatigen Druckmaschine bekannt, mit welcher der Bedruckstoff in zwei von vier Druckwerken der Druckmaschine mit einem sogenannten Hybrid- oder UV-Farbsystem beschichtet wird, das durch Bestrahlung mit UV-Licht ausgehärtet wird, bevor der Bedruckstoff in den beiden nachfolgenden Druckwerken mit einem typischen ölbasierenden Offsetdruck-Farbsystem bedruckt und zuletzt in einem anschließenden Lackturm oder Lackwerk ganzflächig mit einem farblosen Lack beschichtet wird, der von den beiden Farbsystemen unterschiedlich stark resorbiert wird oder auf andere Weise chemisch oder physikalisch zusammenwirkt und dadurch den Glanzgrad der Farbschichten divergierend beeinflusst. Mit dieser Einrichtung ist es möglich, Druckerzeugnisse herzustellen, deren Oberflächen stark kontrastierende matte bzw. hochglänzende Teilflächen aufweisen. Dazu ist dort jedoch hinter einem Teil der Druckwerke eine UV-Belichtungsstation erforderlich, was bei handelsüblichen Offsetdruckmaschinen teuere Umbaumaßnahmen erfordert oder gar nicht möglich ist. Außerdem sind Hybrid- oder UV-Farbsysteme teuerer als die typischen ölbasierenden Offsetdruck-Farbsysteme und weisen darüber hinaus eine höhere Toxizität auf.From the DE 200 20 798 U1 A device for producing spot finishes on substrates in a large-format printing machine is already known, with which the substrate is coated in two of four printing units of the printing press with a so-called hybrid or UV color system, which is cured by irradiation with UV light before the substrate is printed in the two subsequent printing units with a typical oil-based offset printing ink system and finally coated in a subsequent coating tower or coating unit over the entire surface with a colorless paint that is absorbed to different degrees by the two color systems or otherwise chemically or physically cooperates and thus the degree of gloss of the color layers influenced divergently. With this device, it is possible to produce printed products whose surfaces have strongly contrasting matt or high-gloss partial surfaces. For this purpose, however, there is behind a part of the printing units, a UV exposure station required, which requires expensive conversion measures in commercial offset printing machines or is not possible. In addition, hybrid or UV color systems are more expensive than the typical oil-based offset color printing systems and, moreover, have higher toxicity.

Weiter ist aus der EP 0620115 A1 bereits eine Einrichtung zum Inline-Beschichten von Bedruckstoffen in Offsetdruckmaschinen bekannt, mit der eine Spotlackierung eines Bedruckstoffs in einem Durchlauf möglich ist. Die bekannte Einrichtung benötigt dazu jedoch zwei den Offsetdruckwerken nachgeschaltete Lackierwerke, von denen das erste, zu den Offsetdruckwerken benachbarte Lackierwerk als Flexodruckwerk ausgebildet ist und ein Aufbringen von schnell verdunstenden wasserbasierenden Flüssigkeiten gestattet, während das zweite, nachgeordnete Lackierwerk zum Beispiel zum vollflächigen Lackieren des Bedruckstoffs dient. Mit der bekannten Einrichtung gelingt es jedoch nicht, Druckerzeugnisse herzustellen, die sowohl sehr matte als auch hochglänzende lackierte Oberflächen aufweisen, welche stark kontrastieren. Außerdem sind Offsetdruckmaschinen mit der bekannten Einrichtung sehr teuer und habe daher keine große Verbreitung gefunden.Next is from the EP 0620115 A1 already a device for inline coating of substrates in offset printing known, with a spot coating of a substrate in a single pass is possible. However, the known device requires two of the offset printing units downstream coating units, of which the first, adjacent to the offset printing units coating unit is designed as a flexographic printing and application of rapidly evaporating water-based liquids allowed while the second, downstream coating unit, for example, for full-surface painting of the substrate , With the known device, however, it is not possible to produce printed products which have both very matt and high-gloss painted surfaces which contrast strongly. In addition, offset printing machines are very expensive with the known device and have therefore found no widespread use.

In der EP 1 237 728 ist ein Verfahren zum Dekorieren zylindrischer Körper beschrieben, mit dem gleichzeitig matte und glänzende Motive dadurch erzeugt werden, dass man für die matten Motive eine mit Mattierungsmitteln, wie z.B. Quarzpulver, versehene versetzte Farbe vor dem anschließenden ganzflächigen Überlackieren mit einem Glanzlack verdruckt. Abgesehen davon, dass es sich hier um eine spezielle Druckvorrichtung für das Bedrucken von zylindrischen Gegenständen handelt, lässt sich mit diesem Verfahren im Endeffekt nur ein begrenzter Kontrast, d.h. Differenz im Glanzwert zwischen den matten und dem glänzenden Bildstellen erzielen.In the EP 1 237 728 is described a method for decorating cylindrical body, with the same matt and shiny motifs are created by printing for the matte motifs provided with matting agents, such as quartz powder, offset color before the subsequent full-surface overcoating with a gloss varnish. Apart from the fact that this is a special printing device for the printing of cylindrical objects, with this method can be achieved in the end only a limited contrast, ie difference in gloss value between the matte and the glossy image areas.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Druckverfahren und insbesondere, aber nicht ausschließlich, ein Bogenoffsetdruckverfahren dahingehend zu verbessern, dass ein Bedruckstoff auf handelsüblichen Druckmaschinen in einem einzigen Durchlauf mit nebeneinander liegenden matten und hochglänzenden Oberflächen erzeugt wird. Weiter liegt der Erfindung die Aufgabe zugrunde, allein unter Verwendung von handelsüblichen Offsetdruckmaschinen und herkömmlichen ölbasierenden Offsetdruckfarben ein Druckerzeugnis mit einem hohen Kontrast der nebeneinander angeordneten matten und hochglänzenden Oberflächen herzustellen.Proceeding from this, the object of the invention is to improve a printing method and in particular, but not exclusively, a sheetfed offset printing method such that a printing substrate is produced on commercially available printing machines in a single pass with matte and high-gloss surfaces lying next to one another. Further, the invention is based on the object alone using commercial offset printing machines and conventional oil-based offset printing inks a printed product with a high contrast juxtaposed matte and high gloss Produce surfaces.

Diese Aufgabe wird im Hinblick auf das im Anspruch 1 angegebene Verfahren erfindungsgemäß dadurch gelöst, dass ein Bedruckstoff während eines Durchlaufs durch eine Offset- bzw. Flexodruckmaschine (2) mit mehreren Druckwerken (6, 8, 10, 12) und einem nachgeschalteten Lackwerk (14) zuerst in mindestens einem der Druckwerke (6, 8, 10) mit einer ölbasierenden Druckfarbe bedruckt wird, bei dem der Bedruckstoff anschließend in einem nachfolgenden Druckwerk (12) auf einem Teil der mit Druckfarbe bedruckten Fläche mit einem ölbasierenden Mattlack beschichtet wird, der Mattierungsmittel enthält, wobei dem Mattlack ein oder mehrere Stoff(e) zugesetzt sind, die eine niedrige Oberflächenenergie besitzen, und bei dem der Bedruckstoff danach im Lackwerk (14) auf der gesamten bedruckten Fläche mit einem transparenten Glanzlack überzogen wird.This object is achieved with regard to the method specified in claim 1, characterized in that a substrate during a run through an offset or flexographic printing machine (2) with multiple printing units (6, 8, 10, 12) and a downstream coating unit (14 ) is first printed in at least one of the printing units (6, 8, 10) with an oil-based ink, wherein the substrate is then coated in a subsequent printing unit (12) on a part of the ink-printed surface with an oil-based matt paint, the matting agent contains, wherein the mat lacquer one or more substance (s) are added, which have a low surface energy, and in which the substrate is then coated in the coating unit (14) on the entire printed surface with a transparent gloss varnish.

Das erfindungsgemäße Druckverfahren, das im Kontext dieser Anmeldung sowohl Offsetdruckverfahren als auch Flexodruckverfahren umfasst, kann ohne weiteres in handelsüblichen Druckmaschinen durchgeführt werden, da die teilflächige Beschichtung mit dem ölbasierenden Mattlack in einem der z.B. Offsetdruckwerke durchgeführt werden kann, ohne dass dieses dazu umgerüstet oder modifiziert werden muss. Die anschließende ganzflächige Beschichtung mit dem wasserbasierten Glanzlack kann in einem handelsüblichen Lackwerk für Offsetdruckmaschinen durchgeführt werden, an dem allerdings zur Verbesserung des Glanzwertes der späteren glänzenden Teilflächen zweckmäßig einige kleinere und daher leicht durchzuführende Veränderungen vorgenommen werden.The printing process according to the invention, which in the context of this application comprises both offset printing and flexographic printing processes, can readily be carried out in commercial printing presses, since the partial coating with the oil-based matt paint in one of the e.g. Offset printing can be performed without this needs to be converted or modified. The subsequent full-surface coating with the water-based gloss varnish can be carried out in a commercial coating unit for offset printing presses, to which, however, to improve the gloss value of the later shiny part surfaces expediently some smaller and therefore easy to make changes are made.

Der Erfindung liegt der Gedanke zugrunde, die matten bzw. glänzenden Teilflächen des Druckerzeugnisses nicht wie beim Gegenstand der DE 200 20 798 durch Verwendung von zwei unterschiedlichen Farbsystemen zu erzeugen, sondern durch ein einziges Farbsystem aus ölbasierenden Lacken. Es hat sich nämlich gezeigt, dass die durch ihren Gehalt an partikelförmigen Mattierungsmitteln modifizierte Lackschicht wegen des in ihr enthaltenen Stoffes mit niedriger Oberflächenenergie trotz eines anschließenden vollflächigen Auftrags des Glanzlacks ein mattes Aussehen bewahrt.The invention is based on the idea, the matte or glossy faces of the printed product not as in the subject matter of DE 200 20 798 by using two different color systems, but by a single color system of oil-based paints. It has been found that the varnish layer modified by its content of particulate matting agents retains a dull appearance because of the low-surface-energy substance it contains, despite a subsequent full-surface application of the gloss varnish.

Dies geschieht u.a. dadurch, weil der auf den Mattlack aufgetragene Glanzlack durch den beigemischten Stoff mit niedriger Oberflächenenergie daran gehindert wird, den Mattlack gut zu benetzen. Als Stoff mit niedriger Oberflächenenergie von vorzugsweise weniger als 40 milli Newton per Meter und speziell weniger als 25 mN/m kann z.B. Silikonöl, das unter dem Namen "Teflon" bekannte PTFE (Polytetrafluorethylen) oder Derivate dieser Stoffe, wie Hexafluorpropylen, Fluoriertes Ethylen-Propylen Copolymer (FEP), Hostaflon etc. verwendet sein.This happens u.a. because the glossy lacquer applied to the matt lacquer is prevented by the mixed low surface energy substance from wetting the mat lacquer well. As a low surface energy fabric of preferably less than 40 milli Newton per meter and especially less than 25 mN / m, e.g. Silicone oil, the known under the name "Teflon" PTFE (polytetrafluoroethylene) or derivatives of these substances, such as hexafluoropropylene, fluorinated ethylene-propylene copolymer (FEP), Hostaflon be used.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung werden oder der Mattlack und der Glanzlack jeweils aufgebracht, bevor die zuvor aufgebrachte glänzende Druckfarbe bzw. im letzteren Fall auch der zuvor aufgebrachte Mattlack vollständig ausgehärtet bzw. weggeschlagen ist. Dies ermöglicht es, als Druckfarben bzw. Mattlack übliche ölbasierende Offsetdruckfarben bzw. einen ölbasierenden Mattlack zu verwenden, die jeweils ohne zusätzliche Maßnahmen wie UV-Strahler in Offsetdruckwerken von konventionellen Offsetdruckmaschinen auf den Bedruckstoff aufgebracht werden können.According to a further preferred embodiment of the invention, the matt varnish and the gloss varnish are respectively applied before the previously applied glossy printing ink or, in the latter case, the previously applied matt varnish has been completely cured or struck off. This makes it possible to use as printing inks or matt varnish customary oil-based offset printing inks or an oil-based matt varnish which can be applied in each case without additional measures such as UV lamps in offset printing units of conventional offset printing presses on the substrate.

Der verwendete Glanzlack ist vorzugsweise ein wasserbasierter Dispersionslack, da sich wässrige Dispersionslacke zum einen auf den Lackwerken handelsüblicher Offsetdruckmaschinen gut verarbeiten lassen und zum anderen in Verbindung mit der matten Farbe oder dem Mattlack für die gewünschte matte Oberfläche sorgen, während sie auf den nicht mit dem Mattlack beschichteten Teilflächen eine hochglänzende Oberfläche liefern. Vorzugsweise wird ein Dispersionslack auf der Basis eines Styrol-Acrylat-Copolymers verwendet, jedoch können auch Dispersionslacke auf der Basis anderer Polymere verwendet werden.The gloss varnish used is preferably a water-based dispersion varnish, since aqueous dispersion varnishes can be processed well on the varnishing units of commercially available offset printing machines and, on the other hand, provide the desired matt surface in conjunction with the matt or matt varnish, while they do not interfere with the matt varnish coated surfaces provide a high-gloss surface. Preferably, a dispersion paint based on a styrene-acrylate copolymer is used, but also dispersion coatings based on other polymers can be used.

Um für einen möglichst hohen Kontrast zwischen den matten Teilflächen und den glänzenden Teilflächen zu sorgen, wird ein möglichst niedriger Glanzwert der matten Teilflächen und/oder ein möglichst hoher Glanzwert der glänzenden Flächen angestrebt.In order to ensure the highest possible contrast between the matt partial surfaces and the shiny partial surfaces, the lowest possible gloss value of the matt partial surfaces and / or the highest possible gloss value of the glossy surfaces is sought.

Ein möglichst niedriger Glanzwert der matten Teilflächen wird gemäß einer bevorzugten Ausgestaltung der Erfindung dadurch unterstützt, dass der Anteil der Mattierungsmittel so hoch eingestellt wird, wie dies ohne eine Beeinträchtigung der Verarbeitungseigenschaften und der Transparenz des Mattlacks möglich ist. Bevorzugt werden als Mattierungsmittel fein gemahlene Silikate verwendet, wobei jedoch auch andere handelsübliche Mattierungsmittel verwendbar sind. Durch den hohen Anteil an partikelförmigem Mattierungsmittel weist der Mattlack eine raue Oberfläche auf, von welcher der Glanzlack zumindest in kleineren Mengen nahezu vollständig resorbiert werden kann.The lowest possible gloss value of the matt partial surfaces is, according to a preferred embodiment of the invention, supported by the fact that the proportion of matting agents is set as high as is possible without impairing the processing properties and the transparency of the matt lacquer. Finely ground silicates are preferably used as matting agents, although other commercially available matting agents may also be used. Due to the high proportion of particulate matting agent, the matt lacquer has a rough surface, from which the gloss lacquer can be almost completely absorbed, at least in smaller amounts.

Eine ähnliche Wirkung wird erzielt, wenn der Mattlack die zuvor aufgetragene Druckfarbe nur unvollständig benetzt, was ebenfalls zu einer strukturierten Oberfläche führt. Auch dazu trägt das Silikonöl oder PTFE bei, das dem Mattlack, vorzugsweise in einem Bereich von 0,2 bis 0,6 Gew.-%, beigemischt ist. Die durch das z.B. Silikonöl bewirkte unvollständige Benetzung der Offsetdruckfarbenunterlage bewirkt zusammen mit dem Mattierungsmittel, dass der Mattlack nach seinem Auftrag eine gleichmäßige, hammerschlagähnliche, schuppige Oberfläche aufweist.A similar effect is achieved if the matt lacquer wets the previously applied ink only incompletely, which also leads to a structured surface. Also contributes to the silicone oil or PTFE, which is the matte paint, preferably in a range of 0.2 to 0.6 wt .-%, mixed. The Silicone oil caused incomplete wetting of the offset printing ink pad causes, together with the matting agent, that the matt paint after its application has a uniform, hammer-like, scaly surface.

Um beim Auftrag des Glanzlacks einen möglichst hohen Glanzwert der glänzenden Teilflächen zu erzielen, ohne jedoch dabei den Glanzwert der matten Teilflächen wesentlich zu erhöhen, sehen weitere bevorzugte Ausgestaltungen der Erfindung mehrere Maßnahmen vor, die allein oder vorzugsweise in Kombination durchgeführt werden.In order to achieve the highest possible gloss value of the glossy partial surfaces when applying the gloss varnish, but without significantly increasing the gloss value of the matt partial surfaces, see further preferred Embodiments of the invention, several measures, which are carried out alone or preferably in combination.

Eine erste Maßnahme besteht darin, die Menge des aufgetragenen Glanzlacks einerseits ausreichend groß zu machen, so dass sich auf den nicht mit den matt beschichteten Teilflächen eine durchgehende hochglänzende Oberfläche ergibt, andererseits jedoch auch nicht so groß, dass es auf den zuvor mit den matt beschichteten Teilflächen zu einer vollständigen Überflutung und Einebnung der rauen Oberfläche kommt. Versuche in dieser Hinsicht haben ergeben, dass sich beide Vorgaben mit einer Auftragsmenge zwischen 12 und 14 cm3 Glanzlack pro m2 Auftragsfläche erreichen lassen, weshalb der Glanzlack im Lackwerk vorzugsweise mit Hilfe eines Kammerrakels und einer Rasterwalze mit einem Schöpfvolumen von etwa 13 cm3/m2 dosiert wird.A first measure is to make the amount of applied gloss paint on the one hand sufficiently large, so that there is a continuous high-gloss surface on the not coated with the matt surfaces, on the other hand, but not so large that it on the previously coated with the matt Partial surfaces cause a complete flooding and leveling of the rough surface. Experiments in this regard have shown that both specifications can be achieved with an application amount between 12 and 14 cm 3 gloss paint per m 2 application area, which is why the gloss varnish in the coating unit preferably with the aid of a chamber doctor blade and an anilox roller with a Schöpfvolumen of about 13 cm 3 / m 2 is metered.

Eine zweite Maßnahme besteht darin, einen Glanzlack mit einer hohen Viskosität zu verwenden, was ebenfalls einer Einebnung der rauen Oberfläche entgegenwirkt. Zweckmäßig beträgt die Viskosität des Glanzlacks mehr als 70 s-1, vorzugsweise mehr als 75 s-1 und am besten mehr als 80 s-1, gemessen nach DIN 53 211. Die hohe Viskosität des Glanzlacks wird bevorzugt dadurch erreicht, dass der Glanzlack einen hohen Gehalt an Harz enthält, z.B. in Form eines Styrol-Acrylat-Copolymers, wobei dieser Gehalt zweckmäßig mehr als 20 Gew.-%, vorzugsweise mehr als 25 Gew.-% und am besten mehr als 30 Gew.-% beträgt.
Da die genannten hohen Viskositäten des Glanzlacks zu Schwierigkeiten bei seiner Verarbeitung führen können, sieht eine weitere bevorzugte Ausgestaltung der Erfindung vor, den Glanzlack in erwärmtem Zustand auf den bedruckten und teilflächig mit dem matt beschichteten Bedruckstoff aufzubringen, das heißt mit einer Temperatur von mehr als 20°C, vorzugsweise von mehr als 25°C und am besten von mehr als 30°C. Als Voraussetzung dafür wird der Glanzlack zweckmäßig in einem beheizbaren Behälter auf eine Temperatur von mehr als 30°C und vorzugsweise von mehr als 40°C erwärmt und nach Bedarf in das Kammerrakel gepumpt. Um ein Anhaften von Glanzlack an den Wänden des Behälters zu vermeiden, ist dieser vorzugsweise mit einem Rührwerk mit Abstreifern ausgestattet.A second measure is to use a gloss varnish with a high viscosity, which also counteracts a leveling of the rough surface. Suitably, the viscosity of the gloss varnish more than 70 s -1 , preferably more than 75 s -1 and most preferably more than 80 s -1 , measured according to DIN 53 211. The high viscosity of the gloss varnish is preferably achieved in that the gloss varnish a contains high content of resin, for example in the form of a styrene-acrylate copolymer, said content is suitably more than 20 wt .-%, preferably more than 25 wt .-% and most preferably more than 30 wt .-%.
Since the stated high viscosities of the gloss varnish can lead to difficulties in its processing, provides a further preferred embodiment of the invention to apply the gloss varnish in the heated state on the printed and partially coated with the matt-coated substrate, that is with a temperature of more than 20 ° C, preferably greater than 25 ° C, and most preferably greater than 30 ° C. As a prerequisite for the gloss varnish is expediently heated in a heated container to a temperature of more than 30 ° C and preferably more than 40 ° C and pumped as needed into the chambered doctor blade. To avoid adhesion of gloss paint on the walls of the container, this is preferably equipped with a stirrer with scrapers.

Eine dritte Maßnahme besteht darin, die Konzentration eines in wasserdispergierten Glanzlacken normalerweise enthaltenen Benetzungsmittels so weit wie möglich zu senken, zweckmäßig auf weniger als 3 Gew.-%, vorzugsweise auf weniger als 2,5 Gew.-% und am besten auf weniger als 2 Gew.-%, wobei sich diese Werte auf ein Sulfosuccinat als beispielhaftes Benetzungsmittel beziehen. Um zu verhindern, dass es infolge eines derart geringen Gehalts an Benetzungsmittel bei der nachfolgenden Trocknung des auf die feuchte Druckfarbe und den feuchten Mattlack aufgebrachten Glanzlacks zu einer auch als Krakelee oder Rembrandt-Effekt genannten Rissbildung im Glanzlack kommt, enthält der Glanzlack vorzugsweise einen Weichmacher, dessen Gehalt im Glanzlack zweckmäßig zwischen 0,2 bis 1,5 Gew.-% und vorzugsweise zwischen 0,5 und 1 Gew.-% beträgt.A third measure is to reduce as much as possible the concentration of a wetting agent normally contained in water-dispersed gloss paints, suitably to less than 3% by weight, preferably to less than 2.5% by weight and most preferably to less than 2 Wt .-%, wherein these values relate to a sulfosuccinate as an example wetting agent. In order to prevent the formation of cracking in the gloss varnish, which is also called crackle or rembrandt effect, as a result of such a low wetting agent content in the subsequent drying of the varnish applied to the wet printing ink and the moist matt varnish, the varnish preferably contains a plasticizer, its content in the gloss lacquer is advantageously between 0.2 to 1.5 wt .-%, and preferably between 0.5 and 1 wt .-%.

Um ein schnelles schmierfreies Ablegen der aus dem Lackwerk austretenden Bogen beim Bogenoffsetdruck bzw. ein schnelles schmierfreies Aufrollen des bedruckten und lackierten Bedruckstoffs beim Rollenoffsetdruck zu ermöglichen, sieht eine weitere bevorzugte Ausgestaltung der Erfindung vor, den Bedruckstoff nach dem Beschichten mit dem Glanzlack zumindest auf der bedruckten und lackierten Seite mit Warmluft und/oder Wärmestrahlung zu beaufschlagen, um den Glanzlack und die Druckfarbe schneller zu trocknen.In order to enable a fast lubricant-free depositing of the sheet emerging from the coating sheet in sheetfed offset printing or a fast lubrication-free rolling of the printed and coated substrate in web offset printing, provides a further preferred embodiment of the invention, the substrate after coating with the gloss paint at least on the printed Apply hot air and / or heat radiation to the painted side to dry the gloss varnish and the ink more quickly.

Im Hinblick auf das Druckerzeugnis wird die zuvor genannte Aufgabe erfindungsgemäß dadurch gelöst, dass ein Bedruckstoff des Druckerzeugnisses, vorzugsweise Kunstdruckpapier, auf mindestens einer Seite mit ölbasierender Offsetdruckfarbe bedruckt ist, auf einem Teil der Fläche mit einem Mattierungsmittel enthaltenden ölbasierenden matten Lack beschichtet ist, und auf der gesamten bedruckten Fläche, einschließlich der matt beschichteten Teilfläche, mit einem transparenten wasserbasierten Glanzlack beschichtet ist, wobei der matte Lack Silikon oder Teflon oder einen Stoff mit ähnlichen hydrophoben bzw. trennenden Eigenschaften enthält.With regard to the printed product, the aforementioned object is achieved according to the invention in that a printing material of the printed product, preferably art paper, is printed on at least one side with oil-based offset printing ink, coated on a part of the surface with an oil-based matt lacquer containing matting agent, and on the entire printed area, including the matt-coated partial area, is coated with a transparent water-based gloss varnish, the matt varnish containing silicone or Teflon or a substance with similar hydrophobic or separating properties.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt:

  • Fig. 1: eine schematische Seitenansicht einer zum Spotlackieren dienenden Bogenoffsetdruckmaschine mit mehreren Offsetdruckwerken und einem nachgeordneten Lackwerk.
In the following the invention will be explained in more detail with reference to an embodiment shown in the drawing. It shows:
  • Fig. 1 : A schematic side view of a spot for offset sheetfed offset printing press with multiple offset printing units and a downstream coating unit.

Die in der Zeichnung schematisch dargestellte handelsübliche Vierfarben-Bogenoffsetdruckmaschine 2 besteht im Wesentlichen aus einem Bogenanleger 4 (nur teilweise dargestellt), insgesamt vier Offsetdruckwerken 6, 8, 10, 12, einem den Druckwerken 6, 8, 10, 12 nachgeschalteten Lackwerk 14, einer Trocknungseinrichtung 16 sowie einer Bogenauslage 18. In der Druckmaschine 2 werden Bogen aus einem Bedruckstoff, insbesondere aus Kunstdruckpapier, nach ihrem Bedrucken spotlackiert, um unterschiedliche Druckfarben durch eine matte bzw. hochglänzende Oberfläche von verschiedenen Teilen des Druckbildes hervorzuheben, Kontraste zu verstärken, bzw. den Druckfarben ein samtiges oder hochglänzendes Aussehen zu verleihen.The commercial four-color sheetfed offset printing machine 2 shown schematically in the drawing consists essentially of a sheet feeder 4 (only partially shown), a total of four offset printing units 6, 8, 10, 12, a printing units 6, 8, 10, 12 downstream coating unit 14, a Drying device 16 and a sheet delivery 18. In the printing press 2, sheets of a printing material, in particular of art paper, spot-varnished after their printing to emphasize different inks by a matte or glossy surface of different parts of the printed image to enhance contrasts, or the To give printing inks a velvety or glossy appearance.

Zum Bedrucken und Spotlackieren werden die Bogen im ersten, zweiten und dritten Druckwerk 6, 8 und 10 ein- oder mehrfarbig mit handelsüblichen ölbasierenden Offsetdruckfarben bedruckt, anschließend im letzten Druckwerk 12 auf einem Teil der bedruckten Fläche mit einem ölbasierenden Mattlack beschichtet und im nachgeschalteten Lackwerk 14 auf der gesamten bedruckten Fläche mit einem wasserbasierenden Glanzlack überzogen, bevor sie nach einer Trocknung in der Trocknungseinrichtung 16 als fertige Druckerzeugnisse mittels der Bogenauslage 18 auf einem Bogenstapel 20 abgelegt werden. Die teilflächige Beschichtung des Bedruckstoffs mit dem Mattlack erfolgt im Offsetdruckverfahren im letzten Druckwerk 12 der Druckmaschine 2. Das Druckwerk 12 ist dazu wie üblich mit einem Druckzylinder 22, einem Gummituchzylinder 24, einem Plattenzylinder 26, einem Farbwerk 28, sowie einem Feuchtwerk 30 ausgestattet, wobei das Farbwerk 28 zur Dosierung des Mattlacks dient, der dann zusammen mit Feuchtmittel aus dem Feuchtwerk 30 über den Plattenzylinder 26 bzw. eine darauf aufgespannte Druckplatte und den Gummituchzylinder 24 auf den vom Druckzylinder 22 getragenen Bogen übertragen wird. Dabei wird der Mattlack auf diejenigen Teilbereiche der Plattenzylinders 26 bzw. des Bogens aufgebracht, die den matten Teilflächen des fertigen Druckerzeugnisses entsprechen, während das Feuchtmittel auf die übrigen Teilbereiche aufgebracht wird, das heißt diejenigen, die den glänzenden Teilflächen des fertigen Druckerzeugnisses entsprechen. Der Auftrag des Mattlacks auf die Offsetdruckfarben erfolgt feucht in feucht, d.h. vor einer vollständigen Trocknung der Druckfarben durch Wegschlagen und Vernetzung.For printing and spot varnishing the sheets in the first, second and third printing unit 6, 8 and 10 are printed one or more colors with commercial oil-based offset inks, then coated in the last printing unit 12 on a portion of the printed area with an oil-based matt lacquer and in the downstream coating unit 14th coated with a water-based gloss varnish on the entire printed surface before drying in the drying device 16 are stored as finished printed products by means of the sheet delivery 18 on a sheet stack 20. The printing unit 12 is for this purpose as usual with a printing cylinder 22, a blanket cylinder 24, a plate cylinder 26, an inking unit 28, and a dampening unit 30 equipped with the inking unit 28 is used for dosing the matt varnish, which is then transferred together with dampening solution from the dampening unit 30 on the plate cylinder 26 and a pressure plate spanned thereon and the blanket cylinder 24 on the sheet 22 supported by the printing cylinder. In this case, the matt lacquer is applied to those portions of the plate cylinder 26 and the sheet corresponding to the matte faces of the finished printed product, while the dampening solution is applied to the remaining portions, that is, those corresponding to the glossy faces of the finished printed product. The application of the matt lacquer on the offset printing inks is wet in damp, ie before complete drying of the printing inks by knocking off and crosslinking.

Der verwendete Mattlack weist eine ähnliche Zusammensetzung wie die handelsüblichen ölbasierenden Offsetdruckfarben auf, enthält jedoch keine Farbpigmente, dafür aber einen hohen Anteil an Mattierungsmittel in Form von fein gemahlenen Silikaten, sowie 0,2 bis 0,6 Gew.-% Silikonöl oder eine andere Silikonverbindung, die dafür sorgt, dass die vor dem Mattlack aufgebrachten Offsetdruckfarben vom Mattlack nicht vollständig bzw. nicht ganz gleichmäßig benetzt werden. Vorzugsweise wird ein Mattlack mit sehr hohem Mattierungsgrad verwendet, der von der Aquaprint GmbH in Hoyen, Deutschland, unter der Bezeichnung Hi Dual 0 700 Matteffect Litho Varnisch angeboten wird.The matte lacquer used has a composition similar to the commercial oil-based offset inks, but contains no color pigments, but contains a high proportion of matting agents in the form of finely ground silicates, and 0.2 to 0.6 wt .-% silicone oil or another silicone compound , which ensures that the offset inks applied before the matt varnish are not completely or evenly wetted by the matt varnish. Preferably, a matt lacquer with a very high degree of matting is used, which is offered by Aquaprint GmbH in Hoyen, Germany, under the name Hi Dual 0 700 Matte Litho Lithic.

Die bedruckten und teilflächig mit dem Mattlack beschichteten Bogen werden anschließend im Lackwerk 14 vollständig mit dem wasserbasierenden Glanzlack überzogen, bei dem es sich um einen modifizierten transparenten Dispersionslack auf der Basis eines Styrol-Acrylat-Copolymers handelt.The printed sheets which have been partially coated with the matt lacquer are then completely coated in the coating unit 14 with the water-based gloss lacquer, which is a modified transparent dispersion lacquer based on a styrene-acrylate copolymer.

Um zu verhindern, dass die mit dem Mattlack beschichteten Teilflächen, die eine im Vergleich zu den anderen Teilflächen unebene Oberfläche aufweisen, mit dem Glanzlack "überschwemmt" und dadurch eingeebnet werden, wird der Anteil des Styrol-Acrylat-Copolymers im Dispersionslack auf einen Wert von mehr als 25 Gew.-% eingestellt, um die Viskosität des Dispersionslacks (gemessen nach DIN 53 211) auf mehr als 75 s-1 zu erhöhen. Um Schwierigkeiten bei der Verarbeitung eines derart hochviskosen Lacks zu vermeiden, ist das Lackwerk 14 mit einem beheizbaren Lackbehälter 34 ausgestattet, in dem der Lack bei einer Temperatur von etwa 40°C mittels eines Rührwerks mit Abstreifern (nicht dargestellt) ständig in Bewegung gehalten wird, um sein Anhaften an den Wänden des Behälters 34 zu verhindern.In order to prevent the surfaces coated with the matt varnish, which have a surface which is uneven compared with the other part surfaces, being "flooded" with the gloss varnish and thereby being leveled, the proportion of the styrene-acrylate copolymer in the dispersion varnish becomes adjusted more than 25 wt .-%, in order to increase the viscosity of the dispersion varnish (measured according to DIN 53 211) to more than 75 s -1 . To avoid difficulties in processing such a highly viscous paint, the coating unit 14 is equipped with a heatable paint container 34 in which the paint at a temperature of about 40 ° C by means of a stirrer with scrapers (not shown) is kept in constant motion, to prevent it from adhering to the walls of the container 34.

Außerdem wird der Anteil an Sulfosuccinat im Glanzlack, einem für solche transparenten Dispersionslacke im Offsetdruck üblichen Benetzungsmittel, auf einen Wert von kleiner 3 Gew.-% eingestellt, am besten auf einen Gehalt von 2 bis 2,5 Gew.-%. Da dies bei der nachfolgenden Trocknung des Druckerzeugnisses ggf. zu einer Rissbildung (Rembrandt-Effekt) führen könnte, werden dem Glanzlack zusätzlich 0,1 bis 1 Gew.-% eines Weichmachers zugemischt.In addition, the proportion of sulfosuccinate in the gloss varnish, a wetting agent customary for such transparent dispersion varnishes in offset printing, adjusted to a value of less than 3 wt .-%, most preferably to a content of 2 to 2.5 wt .-%. Since this could possibly lead to cracking (Rembrandt effect) during the subsequent drying of the printed product, 0.1 to 1% by weight of a plasticizer is additionally added to the gloss finish.

Darüber hinaus wird der Glanzlack im Lackwerk 14 in einer genau definierten begrenzten Menge aufgetragen, mit der einerseits auf den nicht mit Mattlack beschichteten Teilflächen noch eine ausreichende hochglänzende Oberfläche erzielt werden kann, andererseits jedoch der Glanzlack auf den matt lackierten Teilflächen nahezu vollständig resorbiert wird, ohne den Mattwert dieser Flächen wesentlich zu erhöhen. Versuche haben ergeben, dass dies bei einer Glanzlackmenge von etwa 13 cm3/m2 beschichteter Bedruckstofffläche der Fall ist. Zur Dosierung des Glanzlacks ist das Lackwerk 14 mit einem Kammerrakel 36 und einer Rasterwalze 38 versehen, deren Schöpfvolumen etwa bei dem oben genannten Wert von 13 cm3/m2 liegt. Von der Rasterwalze 38 wird der Glanzlack mittels eines Form- oder Gummituchzylinders 40 auf die Bogen übertragen.In addition, the gloss varnish in the coating unit 14 is applied in a precisely defined limited amount, on the one hand on the not coated with matt varnish surfaces still a sufficient high-gloss surface can be achieved, on the other hand, however, the gloss varnish is almost completely absorbed on the matt lacquered surfaces, without significantly increase the matte value of these surfaces. Experiments have shown that this is the case with a gloss paint amount of about 13 cm 3 / m 2 coated substrate surface. For metering the gloss varnish, the varnishing unit 14 is provided with a chambered doctor blade 36 and an anilox roller 38, whose scoop volume is approximately at the above-mentioned value of 13 cm 3 / m 2 . From the anilox roller 38, the gloss lacquer is transferred to the sheets by means of a blanket or blanket cylinder 40.

Nach der Beschichtung mit dem Glanzlack wird das fertige Druckerzeugnis in der Trocknungseinrichtung 16 mit Hilfe von Infrarotstrahlern und/oder durch Warmluftzufuhr zumindest auf der bedruckten und lackierten Seite getrocknet, bevor es auf dem Stapel 20 abgelegt wird.After coating with the gloss varnish, the finished printed product is dried in the drying device 16 with the aid of infrared radiators and / or by supplying hot air at least on the printed and varnished side, before it is deposited on the stack 20.

Unter den oben genannten Druckbedingungen kann man unter Verwendung eines Bedruckstoffs aus Kunstdruckpapier in einem Druck- und Lackierdurchgang durch die Druckmaschine 2 ein Druckerzeugnis erhalten, das zugleich, d.h. nebeneinander, bedruckte Teilflächen mit einer matten bzw. hochglänzenden Oberfläche aufweist, von denen die erstere einen Glanzwert von etwa 20 % und die letztere einen Glanzwert von etwa 80 % aufweist (jeweils gemessen unter einem Lichteinfalls- und Lichtausfallswinkel von 60 Grad), so dass die Differenz etwa 60 % beträgt, was bisher auf handelsüblichen Druckmaschinen nicht erreicht werden konnte.Under the above-mentioned printing conditions, by using a printing substrate of art paper in a printing and painting pass through the printing press 2, a printed matter can be obtained which at the same time, i. side by side, having printed faces with a matte finish of which the former has a gloss value of about 20% and the latter a gloss value of about 80% (each measured at a light incidence and light drop angle of 60 degrees) such that the Difference is about 60%, which could not be achieved so far on standard printing presses.
