Description

Die vorliegende Erfindung betrifft ein Verfahren zur Übertragung eines Drucks auf ein Substrat, bei dem ein Verbundkörper, bestehend aus einer apolaren Kunststofffolie, einseitig und vollflächig mit einem Schutzlack beschichtet wird, auf den anschließend ein Druck aufgetragen wird, wonach der Verbundkörper auf ein mit einem Haftmittel beschichtetes Substrat, mittels eines Druckstempels und ohne eine zusätzliche Wärmebehandlung übertragen wird und die Kunststofffolie anschließend von dem Schutzlack abgezogen wird. Ferner betrifft die Erfindung die Verwendung eines Verbundkörpers zur Übertragung eines Drucks auf ein Substrat, bestehend aus einer apolaren Kunststofffolie, die einseitig und vollflächig mit einem bedruckten Schutzlack beschichtet ist.The present invention relates to a method of transferring a print to a substrate in which a composite body consisting of an apolar plastic film is coated on one side and over the entire surface with a protective varnish to which a pressure is then applied, after which the composite body is coated with an adhesive coated substrate, is transferred by means of a plunger and without an additional heat treatment and the plastic film is then removed from the protective lacquer. Furthermore, the invention relates to the use of a composite body for transmitting a print to a substrate, consisting of an apolar plastic film, which is coated on one side and the entire surface with a printed protective lacquer.

Üblicherweise wird bei Transferdruckverfahren das nachteilbehaftete Heat-TransferVerfahren eingesetzt, bei dem ein Verbundmaterial seitenverkehrt bedruckt wird. Mittels Hitze und Anpressdruck wird das Druckbild anschließend auf das gewünschte Substrat übertragen. Das verbliebene Verbundmaterial wird danach abgezogen und das Druckbild hält auf dem Substrat.Usually, in heat transfer processes, the disadvantageous heat transfer process is used in transfer printing processes in which a composite material is printed reversed. By means of heat and contact pressure, the printed image is then transferred to the desired substrate. The remaining composite material is then peeled off and the printed image adheres to the substrate.

Nachteilig ist die komplexe und kostenintensive Herstellung dieser bedruckten Heat-Transfer Verbundmaterialien sowie deren Applikation auf das Substrat mittels Hitze. Bekannte Kalttransferverfahren, wie sie beispielsweise in DE 10 2008 047 095 offenbart sind, nutzen komplex ausgestaltete Verbundmaterialien, die eine zusätzliche Antihaftbeschichtung besitzen, womit derartige Verfahren aufgrund der zu verwendenden hochwertigen Transferfolie kostenintensiv sind.A disadvantage is the complex and cost-intensive production of these printed heat transfer composite materials and their application to the substrate by means of heat. Known cold transfer method, as used for example in DE 10 2008 047 095 disclosed use complex designed composite materials, which have an additional non-stick coating, whereby such methods are cost-intensive due to the high-quality transfer film to be used.

Daher ist es die Aufgabe der vorliegenden Erfindung, ein Transferdruckverfahren vorzuschlagen, bei dem diese Nachteile behoben werden und bei dem dennoch ein hochwertiges Druckbild entsteht.It is therefore the object of the present invention to propose a transfer printing method in which these disadvantages are eliminated and in which nevertheless a high-quality printed image is formed.

Diese Aufgabe wird durch das Verfahren nach Anspruch 1 sowie die Verwendung nach Anspruch 5 gelöst.This object is achieved by the method according to claim 1 and the use according to claim 5.

Erfindungsgemäß ist der Verbundkörper auf der dem Schutzlack abgewandten Seite beschichtungsfrei, insbesondere silikonfrei, so dass der Verbundkörper nach dem Druckauftrag und vor der Applikation auf das Substrat derart zu einer transportfähigen Rolle aufgewickelt wird, dass ein späteres Abwickeln rückstandsfrei erfolgt. Das rückstandsfreie Ablösen ermöglicht den Transfer eines hochwertigen Druckbildes, da alle Farbpartikel des Drucks transferiert werden und beim Abwickeln der Rolle keine Rückstände des Drucks auf der dem eigentlichen Druckbild abgewandten Seite bleiben. Auf eine zusätzliche Beschichtung des Verbundkörpers kann verzichtet werden, was sowohl einen zusätzlichen Arbeitsschritt als auch einen weiteren Materialeinsatz einspart.According to the invention, the composite body is free of coating on the side facing away from the protective coating, in particular silicone-free, so that the composite body is wound up into a transportable roll after the print job and before application to the substrate in such a way that subsequent unwinding takes place without residue. The residue-free detachment enables the transfer of a high-quality print image, since all the color particles of the print are transferred and remain during unwinding of the roll no residues of the print on the side facing away from the actual print image. An additional coating of the composite can be dispensed with, which saves both an additional step and a further use of materials.

Vorteilhafterweise erfolgt die Druckübertragung nach dem erfindungsgemäßen Verfahren ohne eine separate und zusätzliche Wärmezufuhr, weshalb dieses Verfahren auch ohne eine kostenintensive Thermopresse durchführbar ist. Darüber hinaus kann der Verbundkörper vorteilhafterweise bereits im bedruckten Zustand - vorzugsweise in Form von Rollen - an die jeweiligen Abnehmer ausgeliefert werden, die vor Ort die Substrate mit einem Haftmittel beschichten und den Drucktransfer in ihrem bestehenden Produktionsprozess durchführen können. Die Übertragung des Drucks ist dadurch möglich, dass eine apolare Kunststofffolie verwendet wird, an der der Druck, die Druckfarbe und/oder der Schutzlack nicht haften. Hierdurch können auch sehr hochwertige Druckbilder übertragen werden. Die Qualitätsanforderungen an das Haftmittel sind nicht außerordentlich hoch, so dass jeder Abnehmer mit einfachen Mitteln die gewünschten Druckbilder auf entsprechende Substrate übertragen kann.Advantageously, the pressure transfer takes place according to the inventive method without a separate and additional heat, which is why this method can be carried out without a costly thermal press. In addition, the composite can advantageously be delivered already in the printed state - preferably in the form of rolls - to the respective customers who coat the substrates with an adhesive on site and can perform the pressure transfer in their existing production process. The transfer of the print is possible by using an apolar plastic film to which the print, the printing ink and / or the protective varnish do not adhere. This also allows very high-quality print images to be transferred. The quality requirements for the adhesive are not extremely high, so that each customer can easily transfer the desired printed images to corresponding substrates.

Auch die erfindungsgemäße Verwendung des Verbundkörpers zeichnet sich dadurch aus, dass der Verbundkörper auf der dem Schutzlack abgewandten Seite beschichtungsfrei ist, insbesondere silikonfrei, so dass der Verbundkörper zu einer transportfähigen Rolle aufwickelbar ist und die Rolle rückstandsfrei abwickelbar ist. Durch die erfindungsgemäße Verwendung ergeben sich die zuvor genannten Vorteile in analoger Weise.The inventive use of the composite is characterized in that the composite on the side facing away from the protective coating is free of coating, in particular silicone-free, so that the composite body can be wound into a transportable role and the role is unprocessed without residue. By the use according to the invention, the advantages mentioned above result in an analogous manner.

Vorteilhafte Weiterbildungen der vorliegenden Erfindung werden im Folgenden und in den Unteransprüchen angegeben.Advantageous developments of the present invention are given below and in the subclaims.

Alternativ zur Applikation des Haftmittels auf das Substrat kann das Haftmittel auch unmittelbar auf den Druck aufgetragen werden. Vorzugsweise wird hierzu ein semipermanenter Haftklebstoff verwendet, der auf der apolaren Kunststofffolie nicht haftet und daher im Wesentlichen rückstandfrei ablösbar ist, so dass der Verbundkörper mit einem solchen Haftmittel zu Transportzwecken ohne weiteres aufrollbar ist.As an alternative to the application of the adhesive to the substrate, the adhesive can also be applied directly to the print. Preferably, a semi-permanent pressure-sensitive adhesive is used for this purpose, which does not adhere to the apolar plastic film and therefore substantially residue-free detachable, so that the composite body with such an adhesive for transport purposes can be rolled up easily.

Nach einer bevorzugten Ausführungsform der Erfindung ist die Kunststofffolie eine Polyolefin-Folie, die vorzugsweise vollständig oder zumindest teilweise aus Polypropylen besteht. Derartige Materialien haben sich als besonders geeignet zur Anwendung des Verfahrens erwiesen, da Farben und Schutzlacke hierauf nicht haften. Hieraus ergibt sich gegenüber herkömmlichen Verbundkörpern der Vorteil, dass er silikonfrei sein kann und auf die Auftragung einer zusätzlichen Silikonschicht verzichtet werden kann.According to a preferred embodiment of the invention, the plastic film is a polyolefin film which preferably consists entirely or at least partially of polypropylene. Such materials have proven to be particularly suitable for the application of the method, since colors and conformal coatings are not liable to this. This results compared to conventional composites of the advantage that it can be free of silicone and can be dispensed with the application of an additional silicone layer.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das Substrat ein Behälter, ein Folienverbund, eine Folie oder ein anderes Applikationsgut ist. Die Vorteile der Erfindung zeigen sich insbesondere an dem Beispiel, dass das Substrat ein Behälter ist, auf den der Druck in der Abfülllinie und damit unmittelbar beim Abnehmer übertragen werden kann. Hierdurch werden Transportkosten der sonst zu bedruckenden Behälter in großem Umfang eingespart, da lediglich die bedruckten Verbundkörper an die Abnehmer ausgeliefert werden müssen, die im Vergleich zu den Behältern ein wesentlich geringeres Volumen einnehmen und mithin geringere Transportkosten verursachen.According to a further preferred embodiment of the invention, it is provided that the substrate is a container, a film composite, a film or another application material. The advantages of the invention are particularly apparent from the example that the substrate is a container to which the pressure in the filling line and thus can be transmitted directly to the customer. As a result, transport costs of the otherwise to be printed containers are largely saved, since only the printed composite body must be delivered to the customer, which occupy a much lower volume compared to the containers and thus cause lower transport costs.

Das Haftmittel wird vorzugsweise mittels eines geeigneten Verfahrens, insbesondere mittels eines Inkjetverfahrens oder eines Druckverfahren über Druckrollen, aufgetragen, mit dem einerseits die Kontur des Druckbildes exakt und andererseits auch mit einer gleichmäßigen Dicke auf das Substrat aufgetragen werden kann. Als geeignete Haftmittel haben sich Hotmelts oder Haftklebstoffe erwiesen, wobei Haftklebstoffe vorzugsweise mittels eines Transferbandes, insbesondere eines silikonisierten Trägerbandes, aufgetragen werden.The adhesive is preferably applied by means of a suitable method, in particular by means of an inkjet method or a printing method via pressure rollers, with the one hand, the contour of the printed image can be applied exactly and on the other hand with a uniform thickness on the substrate. As appropriate Adhesives have been hotmelts or pressure-sensitive adhesives, with pressure-sensitive adhesives are preferably applied by means of a transfer belt, in particular a siliconized carrier tape.

Die einzelnen Verfahrensschritte zur Übertragung eines Drucks von einem Verbundkörper 1 auf einen Behälter 6 sind in den Fig. 1 a und 1 b dargestellt. Hierzu wird zunächst eine Kunststofffolie 2 einseitig mit einem Schutzlack 3 beschichtet. Anschließend wird der Schutzlack 3 in einer Druckmaschine 4 bedruckt. Nach dem Druckvorgang liegt der bedruckte Verbundkörper 1 in einer transportfähigen Form vor und kann gegebenenfalls zu einer Rolle 5 aufgerollt werden, wobei die dem Druck und dem Schutzlack 3 abgewandten Seiten beschichtungsfrei sind.The individual process steps for transmitting a pressure from a composite body 1 to a container 6 are in the Fig. 1 a and 1 b shown. For this purpose, first a plastic film 2 is coated on one side with a protective lacquer 3. Subsequently, the protective coating 3 is printed in a printing press 4. After the printing process, the printed composite body 1 is in a transportable form and can optionally be rolled up into a roll 5, wherein the sides facing away from the printing and the protective coating 3 are free of coating.

Zur Übertragung des Drucks 21 wird der Behälter 6 mit einem Haftmittel 7 beschichtet, welcher die Kontur des Druckbildes aufweist, und einem Stempel 11 zugeführt, der in Pfeilrichtung 8 beweglich ist. Auch der Verbundkörper 1 wird dem Stempel 11 zugeführt, so dass der bedruckte Verbundkörper 1 von dem Stempel 11 auf den Behälter 6 gepresst wird und womit die Farben zusammen mit dem Schutzlack 3 auf dem Behälter 6 haften. Die Kunststofffolie 2 wird hiernach von dem Schutzlack 3 abgezogen und in Pfeilrichtung 9 abgeführt. Hierdurch liegt der Behälter 6' im bedruckten Zustand mit dem Druck 10 vor.To transfer the pressure 21, the container 6 is coated with an adhesive 7, which has the contour of the printed image, and a punch 11, which is movable in the direction of arrow 8. Also, the composite body 1 is supplied to the punch 11, so that the printed composite body 1 is pressed by the punch 11 on the container 6 and with which the colors adhere to the container 6 together with the protective coating 3. The plastic film 2 is then subtracted from the protective coating 3 and discharged in the direction of arrow 9. As a result, the container 6 'is in the printed state with the pressure 10 before.

Die beschriebene Verfahrensführung lässt sich analog auch für Folien, Folienverbunde und andere Applikationsgüter anwenden, die anstelle des Behälters mit einem Druck versehen werden.The method described can be used analogously for films, film composites and other application goods, which are provided instead of the container with a pressure.

Fig. 2a zeigt den Verbundkörper 1 vor der Übertragung des Drucks, wohingegen Fig. 2b das bedruckte Substrat 23 zeigt. Der Verbundkörper 1 besteht im dargestellten Ausführungsbeispiel aus einer Polypropylenfolie 22 als temporärem Träger mit einem Dicken von 30 µm bis 50 µm, auf dessen Unterseite ein Schutzlack 3 mit einem Druck 21 aufgetragen ist. Der bedruckte Verbundkörper 1 wird auf ein mit einem Haftmittel 7 beschichtetes Substrat 23 gepresst (Pfeilrichtung 24), beispielsweise einem Behälter 6 oder einer Folie oder Folienverbund. Abschließend wird die Folie 22 abgezogen (Fig. 2b, Pfeilrichtung 25), so dass schließlich ein bedrucktes Substrat 23 vorliegt, das mit einem Haftmittel 7, einem Druck 21 und schließlich mit einem Schutzlack 3 beschichtet ist. Fig. 2a shows the composite body 1 before the transmission of the pressure, whereas Fig. 2b the printed substrate 23 shows. The composite body 1 consists in the illustrated embodiment of a polypropylene film 22 as a temporary carrier with a thickness of 30 microns to 50 microns, on the underside of a protective coating 3 is applied with a pressure 21. The printed composite body 1 is pressed onto a substrate 23 coated with an adhesive 7 (arrow direction 24), for example a container 6 or a film or film composite. Finally, the film 22 is removed ( Fig. 2b , Arrow direction 25), so that finally a printed substrate 23 is present, which is coated with an adhesive 7, a pressure 21 and finally with a protective lacquer 3.
