Abstract

A process for which firstly a basic body is produced which is provided at least on the head side with a relief-type illustration and subsequently receives a glossy coating. The intention of the invention is to design a process of this type in such a way that it can be used to manufacture medals which have at least on their head side a combined matt/gloss coating, allow the illustration to be easily recognised, have an elegant appearance and can be produced by a simple process. This is achieved by the fact that, after production of the coating, which has been set to a first gloss value, over the entire surface, a second coating, which has been set to a different gloss value, is applied only to the raised regions of the medal on said first coating. This second coating is preferably produced by embossing using a hot blocking foil by means of a die with an elastic punch head, the elasticity of the punch head and the embossing being matched to each other in such a way that the depressed regions of the relief-type illustration are not included in the embossing operation.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Medaillen, bei dem zunächst ein mindestens auf der Kopfseite mit einer reliefartigen Darstellung versehener Grundkörper hergestellt wird, der anschließend einen glänzenden Überzug erhält.The invention relates to a method for producing medals, in which a base body, which is provided at least on the head side with a relief-like representation, is first produced, which is subsequently given a glossy coating.

Medaillen, wie sie bsp. als Preise bei Sportwettkämpfen oder sonstigen Wettbewerben verwendet werden, besitzen üblicherweise einen Grundkörper aus Metall oder Kunststoff, der mindestens auf seiner Vorder- oder Kopfseite eine reliefartige Darstellung aufweist und mit einem metallisch glänzenden Überzug versehen ist, welcher den Medaillen ein wertvolles, elegantes Aussehen verleihen soll. Dabei werden bislang im wesentlichen entweder hochglänzende oder aber mattglänzende Überzüge aufgebracht. Die Herstellung dieser Überzüge kann galvanisch oder durch Aufdampfen, bei mattglänzenden Überzügen außerdem noch durch Aufspritzen erfolgen.Medals such as used as prizes in sports competitions or other competitions, usually have a base made of metal or plastic, which has a relief-like representation at least on its front or head side and is provided with a shiny metallic coating, which is to give the medals a valuable, elegant appearance . So far, either high-gloss or matt-gloss coatings have been applied. These coatings can be produced galvanically or by vapor deposition, and in the case of matt-gloss coatings also by spraying.

Der galvanische Auftrag wird bei hochglänzenden Überzügen mittels Hochglanzbädern und bei mattglänzenden Überzügen entweder mittels chemisch vorbereiteter Mattglanzbäder oder mittels Hochglanzbädern mit anschließender mechanischer Mattierung, z.B. durch Bürsten, hergestellt. Dabei dienen zur Erzeugung der Farbe golg Gold- oder Messingbäder und zur Erzeugung der Farbe silber Silberbäder.The galvanic application is carried out for high-gloss coatings using high-gloss baths and for matt-gloss coatings either using chemically prepared matt gloss baths or using high-gloss baths with subsequent mechanical matting, e.g. made by brushing. Gold or brass baths are used to produce the color golg and silver silver baths are used to produce the color.

Beim Aufdampfen wird eine Aluminiumschicht auf die Oberfläche des Grundkörpers aufgebracht, die mittels eines Transparentlacks versiegelt wird. Bei hochglänzenden Überzügen ist dieser Transparentlack ein Glanzlack, bei mattglänzenden Überzügen dagegen ein Mattlack. Zur Erzeugung der Farbe gold kann dieser Lack entweder die Farbe bereits enthalten oder nachträglich durch Aufspritzen oder Tauchen mit ihr versehen werden, wobei die Farbe in die oberste Lackschicht eindringt; zur Erzeugung der Farbe silber wird lediglich ein keine Farbe enthaltender bsp. auf seiner Oberfläche aufweisender Lack verwendet.When vapor deposition, an aluminum layer is applied to the surface of the base body, which is sealed with a transparent varnish. This transparent varnish is a glossy varnish for high-gloss coatings, but a matt varnish for matt-gloss coatings. To produce the color gold, this lacquer can either already contain the color or subsequently provided with it by spraying or dipping, the color penetrating into the top layer of lacquer; to produce the color silver, only an example containing no color is used. lacquer on its surface is used.

Beim oben außerdem noch erwähnten Herstellen eines mattglänzenden Überzugs durch Aufspritzen wird ein Mattlack verwendet, der Metallpartikel in feinster Verteilung enthält.In the production of a matt-gloss coating by spraying, which is also mentioned above, a matt lacquer is used which contains metal particles in the finest distribution.

Diese bekannten Überzüge sind jedoch mit Nachteilen behaftet. So sind bei Medaillen mit hochglänzenden Überzügen infolge von Spiegelung bzw. Blendwirkung die Konturen der reliefartigen Darstellung oftmals nur schlecht bzw. gar nicht zu erkennen. Bei Medaillen mit mattglänzenden Überzügen tritt dieser Nachteil zwar nicht auf, doch vermitteln sie nicht - wie die Hochglanzmedaillen - den Eindruck des Edelmetalls, sondern wirken billig. Die Herstellung eines Überzugs, bei dem hochglänzende und mattglänzende Bereiche - bsp. zur Hervorhebung des dargestellten Motivs - abwechseln bzw. miteinander kombiniert sind, ist mit den vorstehend beschriebenen Verfahren nicht möglich.However, these known coatings have disadvantages. For medals with high-gloss coatings due to reflection or glare, the contours of the relief-like representation are often difficult to see or not at all. This disadvantage does not occur with medals with matt-gloss covers, but they do not convey the impression of the precious metal - like the high-gloss medals - but look cheap. The production of a cover in which high-gloss and matt-gloss areas - e.g. to emphasize the motif shown - alternating or combined with one another is not possible with the methods described above.

Aus der DE-PS 28 33 066 ist ein Material zum Übertragen eines Glanzmusters bekannt, das aus einem Träger, einer Trennfläche und zwei Schichten unterschiedlichen Glanzwerts besteht, wobei die erste, dem Träger benachbarte Schicht des einen Glanzwerts sich über die gesamte Fläche des Trägers erstreckt, während die zweite Schicht des anderen Glanzwerts in Form eines Musters auf der ersten Schicht aufgetragen ist. Abgesehen davon, daß sich damit Glanzmuster nur auf im wesentlichen ebenflächige Gegenstände, nicht jedoch auf Medaillen übertragen lassen, die z.T. stark vorstehende Bereiche aufweisen, ist es bei diesem bekannten Material nachteilig, daß für jede Darstellung ein besonderes Muster hergestellt und beim Übertragungsvorgang der zu dekorierende Gegenstand absolut lagegenau zugeführt werden muß. Ähnlich verhält es sich bei dem aus der DE-AS 29 17 417 bekannten Dekorationsverfahren.From DE-PS 28 33 066 a material for transferring a gloss pattern is known, which consists of a carrier, a separating surface and two layers of different gloss values, the first layer of the one gloss value adjacent to the carrier extending over the entire surface of the carrier , while the second layer of the other gloss value is applied in the form of a pattern on the first layer. In addition to the fact that gloss patterns can only be transferred to essentially flat objects, but not to medals, some of which have protruding areas, it is with Sem known material disadvantageous that a special pattern is produced for each representation and the object to be decorated must be supplied absolutely accurate during the transfer process. The situation is similar with the decoration method known from DE-AS 29 17 417.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Medaillen zu schaffen, die mindestens auf ihrer Kopfseite einen kombinierten Matt-Glanz-Überzug aufweisen, die dort vorhandene Darstellung gut erkennen lassen, ein elegantes Aussehen besitzen und verfahrenstechnisch einfach herstellbar sind. Ausgehend von dem eingangs beschriebenen bekannten Verfahren wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß nach Herstellung des auf einen ersten Glanzwert eingestellten vollflächigen Überzugs auf diesen ein nur die erhabenen Bereiche der Medaille erfassender, auf einen anderen Glanzwert eingestellter zweiter Überzug aufgebracht wird.The invention has for its object to provide a method for producing medals which have a combined matt-gloss coating at least on their top side, which can be seen clearly there, have an elegant appearance and are easy to manufacture in terms of process technology. Starting from the known method described at the outset, this object is achieved according to the invention in that after the production of the full-area coating set to a first gloss value, a second coating which only detects the raised areas of the medal and is set to a different gloss value is applied.

Für die Herstellung dieses zweiten Teilflächen-Überzugs des anderen Glanzwerts sind erfindungsgemäß mehrere Möglichkeiten vorgesehen. So erfolgt diese Herstellung bei einer ersten Ausführungsform der Erfindung durch Aufprägen einer Heißprägefolie mittels eines Prägestempels mit elastischem Stempelkopf, wobei die Elastizität des Stempelkopfs und der Prägedruck so aufeinander abgestimmt werden, daß die vertieften Bereiche der reliefartigen Darstellung vom Prägevorgang nicht erfaßt werden, und bei einer zweiten Ausführungsform der Erfindung mithilfe eines Druckverfahrens, insbesondere des Tampaprint-Verfahrens, wobei die Elastizität des Stempelkopfs und die Drucktiefe so aufeinander abgestimmt werden, daß die vertieften Bereiche der reliefartigen Darstellung vom Druckvorgang nicht erfaßt werden.According to the invention, several options are provided for producing this second partial surface coating of the other gloss value. Thus, in a first embodiment of the invention, this production is carried out by stamping a hot stamping foil by means of a stamp with an elastic stamp head, the elasticity of the stamp head and the stamping pressure being matched to one another in such a way that the recessed areas of the relief-like representation are not covered by the stamping process, and in one second embodiment of the invention with the aid of a printing process, in particular the tampa printing process, the elasticity of the stamp head and the printing depth being matched to one another such that the recessed areas of the relief-like representation are not covered by the printing process.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, den zweiten Überzug zunächst als den ersten Überzug vollflächig abdeckende Schicht auszubilden, die anschließend in den erhabenen Bereichen abgetragen wird.In a further embodiment of the invention, it is provided that the second coating is initially designed as a layer covering the entire surface of the first coating, which is then removed in the raised areas.

Mit dem erfindungsgemäßen Verfahren lassen sich konturenscharfe, nobel wirkende Medaillen auf verfahrenstechnisch einfachste Weise herstellen. Die Verfahrensdurchführung ist von der Lage der Medaillen und vor allem auch von der darauf vorgesehenen jeweiligen Darstellung völlig unabhängig; wenn man bedenkt, daß Hersteller solcher Medaillen mehrere Hundert verschiedene Typen (Darstellungen sämtlicher Sportarten, Vereins- und sonstiger Embleme, Jubilämsfälle, Zuchttier- und -pflanzenarten usw.) im Programm haben, so stellt das eine ganz wesentliche Vereinfachung dar.With the method according to the invention, sharp-contoured, noble-looking medals can be produced in the simplest possible process. The procedure is completely independent of the location of the medals and, above all, of the respective presentation provided thereon; If you consider that manufacturers of such medals have several hundred different types (depictions of all sports, club and other emblems, jubilee cases, breeding animals and plant species, etc.) in the program, this represents a very significant simplification.
