Abstract

A process for the reproduction of oil painting and the like, having a relief surface, using a relief mold taken from the original and a thermoplastic foil, imprinted with a color picture corresponding to the original, the foil being molded while being heated and which includes placing the foil upon the relief mold in a fitting alignment and heating the foil essentially homogeneously to its liquefying temperature across its entire surface.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Reproduktion von Ölgemälden und dergleichen mit Reliefoberfläche unter Verwendung einer vom Original abgenommenen Reliefform und einer mit dem dem Original entsprechenden Farbbild bedruckten thermoplastischen Folie, die unter Erwärmung verformt wird.The invention relates to a method for the reproduction of oil paintings and the like with a relief surface using a relief mold removed from the original and a thermoplastic film printed with the original color image, which is deformed under heating.

Zur Reproduktion beispielsweise von Ölgemälden bietet sich zunächst das Kopieren an. Gute Kopien erfordern jedoch viel Sachkenntnis und hohen Zeitaufwand, so dass sie teuer sind und in ihrer Menge nicht der mit der Wohnkultur ansteigenden Nachfrage nachkommen können. Demgegenüber ergibt zwar der zu hoher Wiedergabetreue in Farbe und Auflösung entwickelte Mehrfarben-Kunstdruck preiswerte Nachbildungen, jedoch haftet diesen der Nachteil an, dass die reliefartige räumliche Form des Originals fehlt, die bei einem Ölgemälde oder einem ähnlichen Kunstwerk auch Ausdruckmittel des Künstlers ist und selbst von einem Laien als solches erkannt wird.For the reproduction of oil paintings, for example, copying is the first option. However, good copies require a lot of expertise and a lot of time, so that they are expensive and cannot meet the increasing demand with the home decor. On the other hand, the multicolor art print developed to high fidelity in color and resolution results in inexpensive replicas, but there is the disadvantage that the relief-like spatial form of the original is missing, which in an oil painting or similar work of art is also an expression of the artist and even by a layperson is recognized as such.

Zur Lösung dieses Problems wurden in der DE-C 494894, der FR-A 1521466, der DE-B 2019699 und der DE-A 2352966 Verfahren angegeben, bei welchen auf einen originalgetreuen Mehrfarben-Druck an der Bildseite eine transparente Schicht aus Gelatine bzw. Kunststoff aufgebracht wird, die mittels einer vom Original abgenommenen Form vor oder nach dem Aufbringen die Reliefgestaltung der Originaloberfläche erhält. Damit ist zwar an der durchsichtigen Schicht die reliefartige Oberflächengestaltung nachgeahmt, ergibt jedoch nicht den gleichen Eindruck wie beim Original, da sie nicht wie im Original durch die Farbe gebildet ist, so dass also die Wirkung der durch die durchsichtige Schicht gebildeten Oberfläche ausserordentlich stark vom Betrachtungswinkel, der Beleuchtung und dergleichen abhängig ist.To solve this problem, DE-C 494894, FR-A 1521466, DE-B 2019699 and DE-A 2352966 specified methods in which a transparent layer of gelatin or Plastic is applied, which receives the relief design of the original surface by means of a shape removed from the original before or after application. Although this emulates the relief-like surface design of the transparent layer, it does not give the same impression as the original, since it is not formed by the color as in the original, so that the effect of the surface formed by the transparent layer is extremely strong from the viewing angle dependent on lighting and the like.

Diese Unzulänglichkeiten sind bei Verfahren gemäss dem Oberbegriff des Patentanspruchs 1 ausgeschaltet, die in der FR-A 1493 516 sowie der FR-A 1548337 beschrieben sind. Nach der FR-A 1493516 wird die Reliefform mit Luftdurchgangslöchern versehen. Über die Reliefform wird dann unter Passausrichtung die bedruckte Folie gelegt, über welcher eine dicke Polystyrolfolie angebracht wird. Die dicke Polystyrolfolie wird auf die Erweichungstemperatur der Druckfolie erwärmt. Danach wird durch Unterdruck unterhalb der Reliefform und/oder Überdruck oberhalb der Polystyrolfolie diese zusammen mit der Druckfolie in die Vertiefungen der Reliefform gedrückt, wobei sich die Polystyrolfolie mit der bedruckten Folie verbindet. Damit erhält die bedruckte Folie nach dem Wiedererhärten die Oberflächenform des Originals. Das Verfahren gemäss der FR-A 1548337 entspricht diesem bekannten Verfahren mit der Ausnahme, dass die bedruckte Folie durch Bestrahlung mit Infrarotlicht anstelle der Kontakterwärmung mittels einer Polystyrolfolie erwärmt wird und die Formung allein durch Unterdruck unterhalb der Reliefform erfolgt. Gegenüber den bei den vorangehend genannten Verfahren irzielten durchsichtigen Reliefoberflächensnhichten stellt die sich ergebende farbige Reliefoberfläche der Folie eine Verbesserung dar. Da jedoch bei beiden Verfahren zur Formung der Folie beträchtliche Druckkräfte an derselben wirken, die bei dem ersteren bekannten Verfahren beispielsweise mit 7 kg/cm2 angegeben sind, muss die Folie zur Vermeidung von Einrissen zwangsläufig eine bestimmte Dicke haben. Dies führt wiederum dazu, dass feine Reliefgestaltungen nicht mit ausreichender Originalgetreue reproduzierbar sind. Bei manchen Originalen mag dies zwar nicht von grosser Bedeutung sein, jedoch ergibt sich beispielsweise bei der feinen Maltechnik des Manierismus vornehmlich der Müncher Schule eine merkliche Abweichung vom Original.These shortcomings are eliminated in methods according to the preamble of claim 1, which are described in FR-A 1493 516 and FR-A 1548337. According to FR-A 1493516, the relief shape is provided with air through holes. The printed film is then placed over the relief shape with a registration, over which a thick polystyrene film is attached. The thick polystyrene film is heated to the softening temperature of the printing film. Then, by means of negative pressure below the relief mold and / or overpressure above the polystyrene film, the latter is pressed together with the printing film into the depressions of the relief mold, the polystyrene film being connected to the printed film. This gives the printed film the surface shape of the original after it has hardened again. The process according to FR-A 1548337 corresponds to this known process with the exception that the printed film is heated by irradiation with infrared light instead of contact heating by means of a polystyrene film and the molding is carried out solely by means of negative pressure below the relief mold. The resulting colored relief surface of the film is an improvement over the transparent relief surface layers achieved in the aforementioned processes. However, since both processes for forming the film have considerable compressive forces acting on it, which in the former known process, for example, is 7 kg / cm 2 are specified, the film must necessarily have a certain thickness to avoid tears. This in turn means that fine relief designs cannot be reproduced with sufficient faithfulness to the original. For some originals this may not be of great importance, but for example the Munich School's fine painting technique of mannerism results in a noticeable deviation from the original.

Aus der GB-A-782703 ist ein Reproduktionsverfahren mit einer durch Leinwand hinterlegten Farbbildfolie bekannt, die unter Anwendung eines zusätzlichen Druckes von aussen unter gleichzeitiger Erwärmung von Leinwand und Folie in die Reliefform hineingedrückt wird. Auch hier muss die betreffende Farbbildfolie relativ dick gewählt werden, um Einrisse derselben bei dem Andruck gegen die Reliefform zu vermeiden.GB-A-782703 discloses a reproduction method with a color image film deposited by canvas, which is pressed into the relief shape using an additional pressure from the outside while simultaneously heating the canvas and film. Here too, the color image film in question must be chosen to be relatively thick in order to avoid tearing it when it is pressed against the relief shape.

Bei dem aus der zuvor genannten DE-A-23 52966 bekannten Reproduktionsverfahren muss ebenfalls ein zusätzlicher Druck von aussen aufgebracht werden, was den bereits beschriebenen Nachteil hat.In the case of the reproduction method known from the aforementioned DE-A-23 52966, an additional pressure must also be applied from the outside, which has the disadvantage already described.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren gemäss dem Oberbegriff des Patentanspruchs 1 anzugeben, das preiswerte Reproduktionen mit höchster Originalgetreue ergibt.The invention has for its object to provide a method according to the preamble of claim 1, which results in inexpensive reproductions with the highest original fidelity.

Diese Aufgabe wird erfindungsgemäss mit den im kennzeichnenden Teil des Patentanspruchs 1 genannten Massnahmen gelöst.This object is achieved according to the invention with the measures mentioned in the characterizing part of patent claim 1.

Durch die über ihre Dicke bzw. ihre Stärke homogene Erwärmung der bedruckten Folie auf die Fliesstemperatur erfolgt somit ein Einschmelzen der Folie in die Vertiefungen der Reliefform. Da bei diesem Schmelzvorgang die Folie im wesentlichen durch ihr Eigengewicht verformt wird und daher an ihr insbesondere im Fliesszustand keine starken Kräfte ausgeübt werden müssen, kann die Folie sehr dünn sein, so dass selbst kaum wahrnehmbare Oberflächenformen getreu nachgebildet werden. Ein weiterer Vorteil der somit ermöglichten Verwendung einer sehr dünnen Folie liegt darin, dass aufgrund der sehr geringen Wärmekapazität die zum Bedrucken verwendeten Farben wesentlich kürzer einer Erwärmung ausgesetzt sind, so dass die Gefahr einer Farbverfälschung verringert ist. Ferner ergibt sich daraus ein schnellerer Arbeitstakt, da die Zeiten für Erwärmung und Abkühlung kürzer sind. Ein weiterer Vorteil des erfindungsgemässen Verfahrens besteht darin, dass die verwendete Reliefform ausserordentlich einfach hergestellt werden kann. Nur in ganz besonderen Fällen könnte es notwendig sein, für den Ablass von Lufteinschlüssen unter der schmelzenden Folie mikroskopisch kleine Öffnungen anzubringen.Due to the homogeneous heating of the printed film to the flow temperature over its thickness or thickness, the film is melted into the depressions of the relief shape. Since the film is essentially deformed by its own weight during this melting process and therefore no strong forces have to be exerted on it, especially in the flowing state, the film can be very thin, so that even barely perceptible surface shapes are faithfully reproduced. Another advantage of the use of a very thin film that is thus made possible is that, due to the very low heat capacity, the inks used for printing are exposed to heating for a much shorter time, so that the risk of color falsification is reduced. This also results in a faster work cycle, since the times for heating and cooling are shorter. Another advantage of the method according to the invention is that the relief shape used can be produced extremely easily. Only in very special cases it might be necessary to melt air pockets under the melt make microscopic openings in the film.

Zugleich mit dem Formen der Folie wird auf die Rückseite der Folie eine Stützschicht aufgebracht. Dabei wird vorzugsweise die Stützschicht auf gleiche Weise wie die Folie über ihre Stärke im wesentlichen homogen auf die Fliesstemperatur ihres fliessfähigen Bestandteils erwärmt, so dass dieser zusammen mit der Folie zu der Reliefform hin fliesst und damit einen festen Hintergrund bildet, sobald die Folie die durch die Reliefform gegebene Struktur angenommen hat. Als Stützfolie wird vorzugsweise ein in Polyvinylchlorid eingelagertes Gewebe verwendet, wobei zur möglichst originalgetreuen Ausbildung der Reproduktion als Trägermaterial Leinwand verwendet wird, die mit dem Polyvinylchlorid durchtränkt wird. In diesem Fall erfolgt durch im wesentlichen homogenes Erwärmen der Folie einerseits und der Polyvinylchlorid-Schicht andererseits ein Einfliessen der Folie in die Konturen der Reliefform, das durch das Nachfliessen des Polyvinylchlorids unterstützt ist.At the same time as the film is being formed, a backing layer is applied to the back of the film. The support layer is preferably heated in the same way as the film over its thickness essentially homogeneously to the flow temperature of its flowable component, so that it flows together with the film to the relief form and thus forms a solid background as soon as the film through the Relief form given structure. A fabric embedded in polyvinyl chloride is preferably used as the support film, canvas being used as the carrier material for the reproduction of the reproduction as true to the original as possible, which is impregnated with the polyvinyl chloride. In this case, essentially homogeneous heating of the film on the one hand and the polyvinyl chloride layer on the other hand results in the film flowing into the contours of the relief shape, which is supported by the subsequent flow of the polyvinyl chloride.

Da sich bei dem aufgrund der Erwärmung ziemlich plötzlich erfolgenden Absinken der Folie auf die Reliefform Lufteinschlüsse bilden könnten, ist es vorteilhaft, die Wärmezufuhr von der Mitte der Folie her auseinandergehend zu den Rändern vorzunehmen.Since air inclusions could form when the film sinks to the relief shape quite suddenly due to the heating, it is advantageous to apply the heat from the center of the film to the edges.

Als Erwärmungsverfahren für die Folie bzw. für die Folie zusätzlich der aufgelegten Stützschicht ergeben sich insbesondere folgende: eine Erwärmung mittels eines Hochfrequenzfelds, eine Erwärmung mittels Infrarotstrahlung sowie eine Erwärmung mittels Kontakt-Erwärmung mit einem elastischen Auflage-Element. Im Vergleich zu dem gemäss den früheren Techniken angewandten Ober- oder Unterdrücken ergibt dies keine Veränderung insofern, als durch die Erzeugung des Fliesszustands in der Folie zusammen mit der Stützschicht die Formung entsprechend der Reliefform nicht beeinträchtigt wird, da letztlich sowohl die Folie als auch die darüber angebrachte Stützschicht nicht direkt einem Druck ausgesetzt wird und damit «unbeeinflusst» der Reliefform entsprechende Formen annehmen kann.As a heating method for the film or for the film in addition to the applied support layer, the following result in particular: heating by means of a high-frequency field, heating by means of infrared radiation and heating by means of contact heating with an elastic support element. Compared to the upper or lower pressures used according to the previous techniques, this does not result in any change insofar as the creation of the flow state in the film together with the support layer does not impair the shaping according to the relief shape, since ultimately both the film and the one above it the attached support layer is not directly exposed to pressure and can therefore take on the shape of the relief shape "unaffected".

Die im wesentlichen homogene Erwärmung der Folie sowie auch der Folie zusammen mit der Stützschicht kann dadurch erfolgen, dass eine Erwärmung durch Hochfrequenzenergie auf dielektrische Weise in einem Hochfrequenzfeld erfolgt, mit insbesondere hinsichtlich der Wellenlänge geeignet gewählten Infrarotstrahlen erwärmt wird oder durch Kontakt-Erwärmung mittels einer Auflage ausreichend hoher Wärmeleitfähigkeit eine plötzliche Durchwärmung der Folie zusätzlich der Stützschicht erfolgt.The essentially homogeneous heating of the film and also of the film together with the support layer can take place in that heating is carried out in a dielectric manner in a high-frequency field by means of high-frequency energy, is heated with infrared rays suitably chosen with regard to the wavelength in particular, or is heated by contact heating by means of a pad sufficiently high thermal conductivity, there is a sudden warming of the film in addition to the support layer.

Ob zwar die in Frage kommenden Originale und damit auch die von diesen angenommenen Reliefformen an der Oberfläche zumeist rauh genug sind, unter der schmelzenden Folie befindliche Luft seitlich austreten zu lassen, ist es vorteilhaft, die Erwärmung von der Mitte beginnend und zum Rand fortschreitend vorzunehmen.Whether the originals in question and thus the relief shapes assumed by them on the surface are usually rough enough to allow air under the melting film to escape laterally, it is advantageous to carry out the heating from the middle and progressively to the edge.

Als vorteilhafte Ausgestaltung des Verfahrens wird die verwendete Reliefform zumindest an ihrer Formungsfläche galvanisch metallisiert. Damit ist die Formtreue selbst bei einer hohen Reproduktionsstückzahl gewährleistet. Ferner ergibt sich durch die Oberflächenmetallisierung an der ankommenden schmelzenden Folie eine und gute und schnelle Wärmeableitung, so dass die Folie schnell die richtige endgültige Form annimmt und zudem aufgrund des Abschreckens leicht von der Reliefform lösbar ist. Der jeweiligen Oberflächengestalt entsprechend kann die Reliefform gegebenenfalls - auch bei galvanischer Metallisierung - porös gestaltet und/oder mit Löchern versehen werden.As an advantageous embodiment of the method, the relief shape used is galvanized at least on its shaping surface. This ensures shape accuracy even with a high number of reproductions. Furthermore, the surface metallization on the incoming melting film results in good and rapid heat dissipation, so that the film quickly assumes the correct final shape and is also easily detachable from the relief shape due to the quenching. Depending on the particular surface shape, the relief shape can optionally be made porous and / or provided with holes, even in the case of galvanic metallization.

Zur Vermeidung einer übermässigen Einwirkung von Wärme auf die zum Bedrucken der Folie verwendeten Farben wird die Folie vorzugsweise mit ihrer bedruckten Seite nach unten auf die Reliefform aufgelegt. Dadurch wird die Farbschicht schnell von der Reliefform abgekühlt, wenn sie diese erreicht hat. Vorteilhaft kann hierzu ferner die Reliefform zusätzlich gekühlt werden.To avoid excessive exposure to heat on the inks used to print the film, the film is preferably placed with the printed side down on the relief mold. This quickly cools the layer of paint from the relief shape when it reaches it. For this purpose, the relief shape can also advantageously be additionally cooled.

Die Erfindung ist nachstehend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung noch näher erläutert.The invention is explained in more detail below using an exemplary embodiment with reference to the drawing.

Gemäss der Figur wird über eine die Oberflächengestaltung eines Original-Ölgemäldes oder dergleichen als Negativform wiedergebende Reliefform 1 eine mit dem dem Original entsprechenden Farbbild bedruckte thermoplastische Folie 2 mit der Bildseite 3 nach unten gelegt. Die Herstellung der Reliefform erfolgt nach bekannten Verfahren. Beispielsweise kann von dem Original- Ölgemälde ein Negativ-Hartabguss hergestellt werden, bei dem Polyesterharz verwendet wird. Bei diesem Vorgang können jedoch kleine Schäden entstehen, so dass also der Künstler sein Einverständnis geben muss und gegebenenfalls Restaurierungen am Original vornehmen muss. Wenn es sich bei dem Ölgemälde um ein wertvolles Original eines alten Meisters handelt, kann deshalb dieses Abgussverfahren nicht angewandt werden. In einem solchen Fall muss daher eine äusserst sorgfältige Kopie herangezogen werden, die zwar notgedrungen teuer ist, deren Kosten sich jedoch auf eine grosse Anzahl von Reproduktionsexemplaren verteilen, so dass sie nicht ins Gewicht fallen. Ein weiterer Ausweg in einem solchen Fall besteht darin, dass das Original mittels eines Laserstrahls abgetastet und fotochemisch auf eine Gelatine-Matrize oder dergleichen übertragen wird. Diese wird dann durch Ausgiessen in eine Hartmatrize bzw. in einen Hartabguss umgesetzt. Auf die Formungsfläche der auf diese Weise hergestellten Polyester-Hartmatrize wird galvanisch eine Metallschicht 4 aufgebracht.According to the figure, a thermoplastic film 2 printed with the color image corresponding to the original is placed with the image side 3 down over a relief mold 1 which reproduces the surface design of an original oil painting or the like as a negative form. The relief shape is produced by known methods. For example, a negative hard cast can be made from the original oil painting using polyester resin. However, this process can cause minor damage, so that the artist must give his consent and, if necessary, restore the original. If the oil painting is a valuable original from an old master, this casting process cannot be used. In such a case, an extremely careful copy must therefore be used, which is inevitably expensive, but the costs of which are spread over a large number of copies, so that they are not significant. Another way out in such a case is that the original is scanned by means of a laser beam and transferred photochemically to a gelatin matrix or the like. This is then implemented by pouring into a hard die or into a hard casting. A metal layer 4 is applied galvanically to the molding surface of the polyester hard die produced in this way.

Eine besonders vorteilhafte Herstellung der Reliefform 1 ergibt sich dadurch, dass das Original im sogenannten «Kalt»-Verfahren mit Siliconkautschuk abgegossen wird. Bei diesem Verfahren entsteht keinerlei Beschädigung des Originals, so dass auch sehr wertvolle Originale ohne Bedenken abgeformt werden können. Der Siliconkautschuk-Abguss wird nach entsprechender Abstützung durch eine steife Platte und gegebenenfalls Beschichtung mittels der Metallschicht 4 als Reliefform 1 verwendet.A particularly advantageous production of the relief mold 1 results from the fact that the original is cast with silicone rubber in the so-called “cold” process. This method does not damage the original, so that even very valuable originals can be molded without hesitation. The silicone rubber casting is supported by a rigid plate and if necessary Coating by means of the metal layer 4 is used as the relief shape 1.

Das Bedrucken der Folie 2 an der Bildseite 3 erfolgt beispielsweise nach dem Offset-Verfahren, wobei eine Farbaufnahme des Gemäldes mit äusserst genauen Farbwerten ohne Lichtreflexionen zu genau massgetreuen Offsetfilmen in vier Farben verarbeitet wird. Selbstverständlich ist hierbei auf äusserst genaue Masshaltigkeit zu achten. Sowohl bei der Herstellung dieser Offsetfilme als auch bei der Herstellung der Reliefform können von vorneherein Passmarkierungen ausserhalb des Bildfelds vorgesehen werden, die dann das Ausrichten der bedruckten Folie 2 gegenüber der Reliefform 1 erleichtern.The printing of the film 2 on the image side 3 is carried out, for example, using the offset method, in which a color picture of the painting with extremely precise color values without light reflections is processed into precisely dimensioned offset films in four colors. Of course, you must pay attention to extremely precise dimensional accuracy. Both in the production of these offset films and in the production of the relief shape, registration marks outside the image field can be provided from the outset, which then facilitate the alignment of the printed film 2 with respect to the relief shape 1.

Zur Durchführung des Verfahrens werden die Metallisierungsschicht 4 einerseits und eine oberhalb der bedruckten Folie 2 angeordnete Elektrode 5 an einen Hochfrequenzgenerator 6 angeschlossen. Durch kurzzeitiges Einschalten des Hochfrequenzgenerators 6 wird die Folie dielektrisch auf ihre Fliesstemperatur erwärmt und verformt sich in weniger als 1 Sekunde in die negativ ausgebildete Formungsfläche der Reliefform 1 hinein. Die Metallisierungsschicht 4 dient dabei einerseits als Elektrode und andererseits als Wärmeableitungsschicht, die die Bildseite 3 der Folie in ganz kurzer Zeit erstarren lässt und damit die schnelle und genaue Formung der Folie 2 gewährleistet. Falls die normale Rauhigkeit des Originalgemäldes und damit der Formungsfläche der Reliefform 1 nicht dafür ausreichen sollte, die Abfuhr der in den Vertiefungen unterhalb der Folie eingeschlossenen Luft sicherzustellen, können mikroskopisch kleine Luftkanäle in der Reliefplatte 1 ausgebildet werden, die beispielsweise bei 7 angedeutet sind. Ferner kann auch die Reliefform 1 zugleich mit ihrer Metallisierungsschicht 4 mikroskopisch porös ausgebildet werden, so dass die Luft an der ganzen Fläche der Folie 2 ausweichen kann. Die Elektrode 5 kann je nach den Gegebenheiten so ausgebildet werden, dass eine gleichmässige homogene Erwärmung der Folie 2 über ihre ganze Stärke und ihre ganzen Ausmasse hinaus gewährleistet ist. Durch geeignete Formung der Elektrode 5 kann jedoch auch eine etwas höhere oder etwas früher einsetzende Erwärmung in der Flächenmitte der Folie erfolgen, was beispielsweise durch Aufteilung der Elektrode 5 und entsprechend zeitlich gestufter Einschaltung der sich ergebenden Teilelektroden vorgenommen werden kann.To carry out the method, the metallization layer 4 on the one hand and an electrode 5 arranged above the printed film 2 are connected to a high-frequency generator 6. By briefly switching on the high-frequency generator 6, the film is dielectrically heated to its flow temperature and deforms into the negatively formed shaping surface of the relief mold 1 in less than 1 second. The metallization layer 4 serves on the one hand as an electrode and on the other hand as a heat dissipation layer, which solidifies the image side 3 of the film in a very short time and thus ensures the rapid and precise shaping of the film 2. If the normal roughness of the original painting and thus the shaping surface of the relief mold 1 should not be sufficient to ensure the removal of the air enclosed in the depressions below the film, microscopic air channels can be formed in the relief plate 1, which are indicated, for example, at 7. Furthermore, the relief mold 1 can also be made microscopically porous with its metallization layer 4, so that the air can escape over the entire surface of the film 2. Depending on the circumstances, the electrode 5 can be designed in such a way that a uniform, homogeneous heating of the film 2 is ensured over its entire thickness and its entire dimensions. By suitable shaping of the electrode 5, however, a somewhat higher or somewhat earlier heating can take place in the middle of the surface of the film, which can be done, for example, by dividing the electrode 5 and correspondingly stepped activation of the resulting partial electrodes.

Die nach dem Verfahren verformte bedruckte Folie 2 ergibt eine extrem genaue Nachbildung des Originals mit den feinsten Strukturen, so dass auch die nahezu glatt wirkenden Oberflächenformen bei der Maltechnik beispielsweise des 19-Jahrhunderts originalgetreu reproduzierbar sind. Das Verfahren ist auch ausserordentlich wirtschaftlich, da durch Wahl einer dünnen Folie ein schnelles Erwärmen und auch ein schnelles Abkühlen erzielbar ist. Die auf die Reliefform 1 galvanisch aufgebrachte Metallisierungsschicht 4 verändert die beim Abdruck erzielte Genauigkeit praktisch überhaupt nicht, was beispielsweise daraus geschlossen werden kann, dass eine derartige Galvanisierung auch bei Schallplattenmatrizen Anwendung findet. Die Metallisierungsschicht 4 ergibt jedoch eine höhere Lebensdauer der Reliefform 1 ohne AbnutzungserRchcillunQen und trägt ferner zu einer schnelleren Abkühlung der in sie eingeschmolzenen bedruckten Folie bei. Dabei ist besonders die schnelle Abkühlung der Bildseite 3 der Folie 2 von Bedeutung, da damit die Gefahr von Farbverfälschungen der benutzten Druckfarben durch die erfolgte Erwärmung verringert wird. Damit ergibt das Verfahren gegenüber den bekannten Verfahren unter einfacherer Herstellung einer Form eine höhere Genauigkeit unter schnellerer und kostengünstigerer Herstellung der Reproduktionen.The printed film 2 deformed by the process results in an extremely precise replica of the original with the finest structures, so that even the almost smooth-looking surface shapes can be reproduced faithfully in the painting technique, for example of the 19th century. The process is also extremely economical, since quick heating and rapid cooling can be achieved by choosing a thin film. The metallization layer 4 electroplated onto the relief shape 1 practically does not change the accuracy achieved during the impression, which can be concluded, for example, that such electroplating is also used for record matrices. However, the metallization layer 4 results in a longer service life of the relief mold 1 without Abnutzungser R chci ll un Q s and also carries the melted into it, printed film to a faster cooling. The rapid cooling of the image side 3 of the film 2 is of particular importance here, since the risk of color falsification of the printing inks used is thus reduced as a result of the heating. In comparison with the known methods, with simpler production of a mold, the method thus results in higher accuracy with faster and cheaper production of the reproductions.

Wie ausserdem in der Fig. gezeigt, ist auf die Folie 2 eine Stützschicht 8 aufgelegt, die zugleich mit der Folie 2 der dielektrischen Hochfrequenz-Erwärmung mittels der Elektrode 5 und der in diesem Fall als Gegenelektrode dienenden Metallisierung 4 der Reliefform unterzogen ist. Die Elektrode 5 kann hierzu leicht auf die Stützschicht 8 aufgelegt werden, wodurch eine besonders konzentrierte Hochfrequenz-Erwärmung zu der Reliefform 1 bzw. zu deren Beschichtung 4 hin erfolgt. Sobald die Folie 2 und möglichst gleichzeitig damit ein fliessfähiger Bestandteil der Stützschicht 8, die beispielsweise aus PVC-getränkter Leinwand bestehen kann, auf die Fliesstemperatur gebracht sind, sinkt zunächst die Folie 2 und danach der fliessfähige Bestandteil der Stützschicht 8 in die jeweiligen Formen der Reliefform 1, wobei ein Gewebe der Stützschicht 8 im wesentlichen in seiner ursprünglichen Form verbleibt. Auf das «Einfliessen» der Folie 2 unter der Gewichtsbelastung durch das Material der Stützschicht 8 in die entsprechenden Vertiefungen der Reliefform 1 wirkt die Schwerkraft. Die Elektrode 5 ist dabei völlig unabhängig von der Aufschichtung der Folie 2 und der Stützschicht 8 festgelegt, so dass bei einem Aufliegen der beiden Schichten sich diese nach ihrer zur Fliesstemperatur hin vorgenommenen Erwärmung von der Elektrode 5 lösen und die gewünschte Form einnehmen.As is also shown in FIG. 1, a support layer 8 is placed on the film 2, which at the same time as the film 2 is subjected to the dielectric high-frequency heating by means of the electrode 5 and in this case the metallization 4 serving as the counter electrode of the relief shape. For this purpose, the electrode 5 can easily be placed on the support layer 8, as a result of which a particularly concentrated high-frequency heating takes place towards the relief mold 1 or its coating 4. As soon as the film 2 and, if possible simultaneously, a flowable component of the support layer 8, which can consist, for example, of PVC-impregnated canvas, are brought to the flow temperature, the film 2 first drops and then the flowable component of the support layer 8 into the respective shapes of the relief shape 1, wherein a fabric of the support layer 8 remains essentially in its original shape. Gravity acts on the "inflow" of the film 2 under the weight load of the material of the support layer 8 into the corresponding depressions of the relief form 1. The electrode 5 is completely independent of the layering of the film 2 and the support layer 8, so that when the two layers are in contact, they detach from the electrode 5 after they have heated to the flow temperature and assume the desired shape.
