Definitions
- the invention relates to a mosaic segment comprising a carrier plate with a surface structure.
- the invention also relates to a mosaic comprising a plurality of mosaic segments joined together, a method for printing a mosaic segment and a method for producing a mosaic segment.
- Mosaics known from the prior art comprise a large number of small mosaic stones which are put together to form a pattern / picture.
- the assembly of the small mosaic stones is extremely complex and the mosaics are correspondingly expensive.
- the tesserae are made of glass and colored with sand oxides [2].
- a mosaic segment according to claim 1 a mosaic according to claim 6, a method for printing a mosaic segment according to claim 9 and a method for producing a mosaic segment according to claim 14.
- the mosaic segment according to the invention comprises a carrier plate with a surface structure, the surface structure comprising a plurality of mosaic structure elements which are grouped so that they form a segment pattern and joints are formed between the mosaic structure elements, the structured carrier plate being designed as a one-piece pressed ceramic part.
- a mosaic assembly can have mosaic structure elements of different sizes and shapes.
- Pressed ceramic is understood to mean, for example, an injection-molded ceramic.
- the injection molding of ceramic materials offers much greater freedom in the part geometry.
- the material properties of the ceramics alone create a better solution from an economic and technical point of view than conventional materials or manufacturing methods.
- the freedom of design of the injection molding process can increase these advantages or enable completely new product ideas to be realized.
- the elements of the mosaic to be produced are not produced as individual elements, but as structural elements of a carrier plate.
- a mosaic segment therefore takes on the function of a large number of conventional tesserae, wherein the tessellated segment can be handled like a single tesserae, since it is only a single part. Due to the planned joints between the mosaic structural elements, the impression of many mosaic stones can still be created.
- the mosaic structural elements are grouped on the carrier plate, i.e. arranged in a predetermined order, and form the segment pattern (i.e. the pattern within a mosaic segment).
- the mosaic segment is also known as a "cluster".
- the design of the mosaic elements shown is such that it can be laid homogeneously in all directions, ie the mosaics are visually arranged in new ways. As the clusters are later grouted, the beginnings and ends of the clusters are no longer visible.
- the mosaic structural elements form elevations.
- the space (joint) between the mosaic structural elements is limited by the carrier plate.
- the width (smallest dimension parallel to the plane of the carrier plate) of the mosaic structure elements is preferably less than 2 cm.
- the distance between adjacent mosaic structure elements is preferably smaller than the width of the mosaic structure elements, in particular less than 1/10 of the width of the mosaic structure elements.
- the mosaic structure elements have rounded contours in plan view (view perpendicular to the plane of the carrier plate), for example round or elongated with rounded corners or organic shapes, for example pebble-like.
- the rounded contours enable serial, transparent glazing of the mosaic elements. Due to the rounded shape, the glaze can flow out completely around the mosaic structure elements. In addition, the rounded elements can later be grouted more precisely by the craftsmen. In principle, however, any shape can be implemented.
- the carrier plate is made of oxide ceramic, in particular made of zirconium oxide ZrO2 or aluminum oxide Al2O3, or silicate ceramic. manufactured. Press ceramic parts of this type are used in dental technology for crowns and bridges [3] and can be manufactured with a high degree of precision as parts off the tool.
- the carrier plate is provided with bores between the mosaic structural elements.
- the boreholes offer the possibility of illuminating the mosaic segment from behind, which means that luminous mosaic images can be generated.
- the mosaic structural elements of the mosaic segment according to the invention are preferably provided with a glaze, the glazed mosaic structural elements having a crown.
- the crowning is brought about by a special glaze technique, which is preferably applied by machine using stainless steel stencils, and is used to create a glossy / luminous effect, since light falling through the crowning falls through the surface to the pure white background of the mosaic structural elements and through the glaze is reflected back. Due to the small contact area, the camber also prevents profound and visible effects when it comes into contact with an object Scratch.
- the mosaic segment according to the invention therefore has a high level of scratch resistance.
- the glaze is preferably an opaque, that is to say light-impermeable, glaze, in particular a white or black opaque glaze.
- the mosaic according to the invention comprises a multiplicity of previously described mosaic segments joined together.
- the joints between the mosaic structural elements are at least partially filled with a joint compound. Both the joints between the mosaic structure elements within a mosaic segment and the joints between the mosaic structure elements of adjacent mosaic segments are grouted.
- the elements of the mosaic according to the invention are not manufactured as individual elements, but rather as structural elements of a carrier plate which comprises a large number of structural elements, very small structural elements can be produced with comparatively little effort.
- the structural elements of the mosaic segment according to the invention are preferably smaller than 1 cm, in particular 0.5 cm or smaller. This makes it possible to create high-resolution mosaic images, for example of portraits, so that the personality traits of the person depicted are not lost.
- the mosaic segments are each arranged rotated with respect to one another with an edge rotation of 90 °.
- the mosaic segments are preferably square.
- the joints between the mosaic structural elements are at least partially filled with a self-illuminating joint compound.
- Self-illuminating is understood to mean, in particular, phosphorescent.
- the impression can be created that the mosaic structure elements are applied to a luminous surface.
- the mosaic segments according to the invention are preferably used to cover an interior wall or a side wall of a ship, in particular a yacht.
- the mosaic segments according to the invention can be used to cover room walls, aircraft walls, furniture, etc.
- the dummy mosaic structure elements of the mosaic segment dummy produced in step a) are arranged in the same segment pattern as the mosaic structure elements of the mosaic segment, ie the geometric arrangement (alignment of the elements to one another) and the proportions (length / width / spacing) of the dummy mosaic structure elements correspond the geometric arrangement and proportions of the corresponding mosaic structural elements of the mosaic segment.
- the size of the mosaic structure elements may differ from that of the dummy mosaic structure elements. This allows flexibility in the choice of material to be used for the mosaic segment dummies. For example, a material with a higher or lower material shrinkage can be used for the mosaic segment dummy than for the mosaic segment.
- the height of the dummy mosaic structure elements is preferably smaller than the height of the mosaic structure elements of the mosaic segment. This enables easy coloring.
- the height of the dummy mosaic structure elements is preferably equal to the height difference between the mosaic structure elements and the joint compound in a fully grouted mosaic segment.
- the coloring in step b) is preferably carried out by applying a glaze, in particular a ceramic glaze.
- a glaze in particular a ceramic glaze.
- the dummy mosaic structure elements are given an individual color distribution.
- Each dummy mosaic structure element is preferably colored in a specific color shade or with a combination of similar color shades, preferably by hand.
- step c) can take place by photographing or scanning.
- Each color distribution stored in step c) preferably receives an individual color code which can be assigned to the respective mosaic structure element areas.
- the corresponding color codes are then transmitted to a printer system together with information that identifies the respective mosaic structure element.
- the creation of the overall pattern in step d) can take place by means of a 2-dimensional arrangement of segment patterns each rotated by 90 ° in relation to one another.
- the size of the overall pattern corresponds to the size of the target motif.
- step e) the target motif is divided according to the mosaic segments of the overall pattern, so that a mosaic structure element area of the target motif is assigned to each mosaic structure element of the overall pattern.
- the colorations present in the mosaic structure element areas are assigned in step f) to those stored color distributions which come closest to the real colorations of the corresponding mosaic structure element areas of the target motif.
- step g) The application of paint to the mosaic structural elements in step g) is preferably carried out by means of brushes or airbrushes.
- the mosaic segment dummies are preferably colored by hand in step b).
- the color by hand there is a unique color distribution for each mosaic structure element.
- printing can be done by machine, and on the other hand, a color distribution is realized that corresponds to that of hand painting. In this way, high-quality mosaics with individual characteristics can be produced in a comparatively inexpensive manner.
- Different materials can be used to produce the mosaic segment dummies and the mosaic segments. While pressed ceramic is preferably used for the mosaic segments that are used for the mosaic to be created in order to minimize shrinkage after firing, a more easily processable material can be used for the mosaic segment dummies, since here it only depends on the proportions of the mosaic structural elements to each other.
- the mosaic segment dummies are preferably made of pourable or paste-like porcelain (because of the impossibility of demolding as a whole cluster, the joints are filled here).
- Porcelain is ideal as a material for the mosaic element dummies, as it is available as a casting compound and has the perfect consistency for glazing by hand.
- the dummies made of castable porcelain have all the properties of the classic "crockery porcelain". In traditional hand painting, this affects the way the glazes are absorbed into the surface - work can be done much more precisely and therefore authentically.
- the carrier plates are preferably manufactured using a method similar to injection molding, in particular using ceramic injection molding [4].
- the tool structure is significantly simplified here; the use of standard parts is dispensed with.
- Ceramic injection molding enables a great variety of shapes with high material quality.
- a certain amount of a polymer material is added to the liquid mass of the carrier plate material (e.g. aluminum oxide) and then "baked” under high pressure in the tool (almost free of shrinkage).
- a polymer material e.g. aluminum oxide
- the surfaces of the mosaic structure elements can be ground flat before glazing. If the process is optimized accordingly, surface grinding can be dispensed with.
- the method described above for printing a mosaic segment is preferably used for printing the mosaic structural elements.
- a muffle glaze method is used for printing. Muffle glazes can be burned in perfectly and are therefore particularly hard. The muffle glaze gives the mosaics a special brilliance in the surface, as the prefabricated elements are delivered with a transparent glaze.
- FIG. 1 to 3 show a mosaic segment 1 according to the invention.
- the mosaic element 1 has a carrier plate 2 with a multiplicity of mosaic structure elements 3 which form a segment pattern 12 .
- There are joints 4 between the mosaic structural elements 3 Figure 3 the joints 4 are filled with a joint compound 5 up to a certain height.
- the joints 4 can be filled with the joint compound 5 before and / or after several mosaic segments 1 have been joined together to form a mosaic 7 (see FIG. Figure 5 ) take place.
- the mosaic structure elements 3 have a curved surface (crown 6 ) and can be designed in different shapes (here three different shapes).
- holes 8 can be provided in the carrier plate 2 in order to enable background lighting, as in FIG Figure 4 shown.
- FIG. 5 shows a plan view of a mosaic 7 according to the invention.
- the mosaic structure elements 3 of all mosaic segments 1 form an overall pattern 9.
- the in Figure 5 The mosaic 7 shown comprises, by way of example, four mosaic segments 1 which are each rotated by 90 ° with respect to one another so that a uniform, repeat-free overall pattern is formed.
- the same mosaic structure element 3 was marked with hatching in each mosaic segment 1.
- the edges of the individual mosaic segments 3 are shown in dashed lines.
- Another possibility to create a repeat-free overall pattern is to move the mosaic segments of different rows against each other, as in the Figures 7 and 8th shown by way of example for mosaic segments with pebble-shaped mosaic structural elements.
- Figure 6 shows on the right a target motif 10, which is based on a mosaic with the in Figure 6 Overall pattern 9 shown on the left is to be shown.
- the individual process steps for printing the corresponding mosaic segments 1 are shown in Figure 9 shown: First of all, the overall pattern 9 is created from individual segment patterns 12 with the aid of software. The number of segment patterns 12 depends on the size and desired resolution of the mosaic to be generated. In Figure 6 below is shown how the target motif 10 is superimposed with the overall pattern 9 in order to divide the target motif 10 into mosaic structure element areas 11 which correspond to the mosaic structure elements of the mosaic to be produced.
- the colors (shown here as hatching) within each mosaic structure element area 11 are analyzed and each mosaic structure element area 11 is assigned a previously provided (stored) color distribution, such that the assigned color distribution corresponds as closely as possible to the colors of the corresponding mosaic structure element area 11. In this way, the colors contained in the target motif are replaced in certain areas by the color distributions provided.
- the mosaic structure elements 3 of the mosaic segments 1 are then printed in accordance with the assigned color distributions.
- At least one mosaic segment dummy 13 is first produced which has dummy mosaic structure elements 14 which form the same segment pattern 12 as the mosaic structure element 1 to be printed, as in FIG Figure 10 shown.
- the mosaic segment dummy 13 usually consists of a different (easy to process material) than the mosaic segment 1 and is preferably painted by hand.
- the dummy mosaic structure elements 14 of the mosaic segment dummy 13 are less raised than the mosaic structure elements 3 of the mosaic segment 1.
- each dummy - Mosaic structure element 14 is provided with a certain color or a combination of similar color shades, whereby the hand-painting means that the dummy mosaic structure elements 14 are not monochrome, but rather have a certain color distribution within the specified color / color combination.
- the mosaic segment dummy 13, which has been colored in such a very complex manner, is then digitally photographed and the color distribution of each dummy mosaic structure element 14 is stored.
- the color distributions stored in this way can be used for a large number of target motifs, so that the method steps described so far relating to the production and coloring of the mosaic segment dummies 13 do not have to be carried out again for each printing process.
- the mosaic segments 1 printed with the method described above are produced by first producing the structured carrier plate 2 with the mosaic structure elements 3 and the joints 4 between them as a pressed ceramic workpiece.
- the mosaic structural elements are then provided with a crown with a glaze and can then be printed using the method described above ( Figure 11 ).

Description
Die Erfindung betrifft ein Mosaiksegment umfassend eine Trägerplatte mit einer Oberflächenstruktur. Die Erfindung betrifft darüber hinaus ein Mosaik umfassend eine Vielzahl an zusammengefügten Mosaiksegmenten, ein Verfahren zum Bedrucken eines Mosaiksegments und ein Verfahren zur Herstellung eines Mosaiksegments.The invention relates to a mosaic segment comprising a carrier plate with a surface structure. The invention also relates to a mosaic comprising a plurality of mosaic segments joined together, a method for printing a mosaic segment and a method for producing a mosaic segment.
Aus dem Stand der Technik bekannte Mosaike umfassen eine Vielzahl an kleinen Mosaiksteinchen, die zu einem Muster/Bild zusammengefügt werden. Das Zusammenfügen der kleinen Mosaiksteinchen ist extrem aufwändig und die Mosaike entsprechend teuer.Mosaics known from the prior art comprise a large number of small mosaic stones which are put together to form a pattern / picture. The assembly of the small mosaic stones is extremely complex and the mosaics are correspondingly expensive.
Für den Luxusbereich werden die Mosaiksteinchen insbesondere aus Glas gefertigt und mit Sandoxiden gefärbt [2].For the luxury sector, the tesserae are made of glass and colored with sand oxides [2].
Um das Aneinanderfügen der Mosaiksteine am Montageort zu erleichtern, ist es insbesondere im Sanitärbereich üblich, 20-45cm2 große Mosaiknetze vorzufertigen, bei denen die Mosaiksteinchen auf ein Netz aus Kunststoff aufgeklebt sind [1], was die Handhabung und Weiterverarbeitung erleichtert.In order to facilitate the joining of the mosaic stones at the installation site, it is common, especially in the sanitary area, to prefabricate 20-45cm 2 large mosaic nets in which the mosaic stones are glued to a plastic net [1], which facilitates handling and further processing.
Da der Aufwand zur Erstellung eines Mosaiks enorm steigt je kleiner die Mosaiksteinchen sind, werden für übliche Mosaike nur ca. 4300 Mosaiksteinchen (Kantenlänge ca. 1,5cm) pro Quadratmeter verwendet. Detailreiche Bilder können daher nur unzureichend aufgelöst werden.Since the effort to create a mosaic increases enormously the smaller the mosaic stones are, only approx. 4,300 mosaic stones (edge length approx. 1.5 cm) per square meter are used for normal mosaics. Detailed images can therefore only be insufficiently resolved.
Es ist Aufgabe der Erfindung Mosaiksegmente bereitzustellen, mit denen auf zeitsparende und einfache Weise präzise Mosaike hergestellt werden können, die eine hohe Anzahl an Mosaikelementen (Mosaikstrukturelemente) aufweisen. Darüber hinaus ist es Aufgabe der Erfindung, ein Verfahren zur Herstellung solcher Mosaiksegmente vorzuschlagen, mit dem einfach und kostengünstig Mosaiksegmente hergestellt werden können, die eine hochwertige, exklusive optische Erscheinung aufweisen.It is the object of the invention to provide mosaic segments with which precise mosaics can be produced in a time-saving and simple manner, which mosaics have a large number of mosaic elements (mosaic structural elements). In addition, it is the object of the invention to propose a method for producing such mosaic segments with which mosaic segments can be produced easily and inexpensively which have a high-quality, exclusive optical appearance.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Mosaiksegment gemäß Anspruch 1, ein Mosaik gemäß Anspruch 6, ein Verfahren zum Bedrucken eines Mosaiksegments gemäß Anspruch 9 und ein Verfahren zur Herstellung eines Mosaiksegments gemäß Anspruch 14.This object is achieved according to the invention by a mosaic segment according to
Das erfindungsgemäße Mosaiksegment umfasst eine Trägerplatte mit einer Oberflächenstruktur, wobei die Oberflächenstruktur eine Vielzahl an Mosaikstrukturelementen umfasst, die so gruppiert sind, dass sie ein Segmentmuster bilden und zwischen den Mosaikstrukturelementen Fugen ausgebildet sind, wobei die strukturierte Trägerplatte als einstückiges Presskeramikteil ausgebildet ist. Dabei kann ein Mosaiksemgent Mosaikstrukturelemente verschiedener Größen und Formen aufweisen.The mosaic segment according to the invention comprises a carrier plate with a surface structure, the surface structure comprising a plurality of mosaic structure elements which are grouped so that they form a segment pattern and joints are formed between the mosaic structure elements, the structured carrier plate being designed as a one-piece pressed ceramic part. A mosaic assembly can have mosaic structure elements of different sizes and shapes.
Unter Presskeramik versteht man bspw. eine spritzgegossene Keramik.Pressed ceramic is understood to mean, for example, an injection-molded ceramic.
Gegenüber spanenden Fertigungsverfahren bietet das Spritzgießen von keramischen Werkstoffen (Ceramic Injection Moulding CIM) eine wesentlich höhere Freiheit in der Teilegeometrie. Alleine die Materialeigenschaften der Keramiken schaffen in vielen Fällen eine aus wirtschaftlicher und technischer Sicht bessere Lösung gegenüber herkömmlichen Materialien oder Fertigungsmethoden. Die Formgebungsfreiheit des Spritzgussverfahrens kann diese Vorteile noch steigern oder ermöglicht erst die Realisation völlig neuer Produktideen.Compared to metal-cutting manufacturing processes, the injection molding of ceramic materials (Ceramic Injection Molding CIM) offers much greater freedom in the part geometry. In many cases, the material properties of the ceramics alone create a better solution from an economic and technical point of view than conventional materials or manufacturing methods. The freedom of design of the injection molding process can increase these advantages or enable completely new product ideas to be realized.
Gemäß der Erfindung werden die Elemente des anzufertigenden Mosaiks nicht als Einzelelemente gefertigt, sondern als Strukturelemente einer Trägerplatte. Ein Mosaiksegment übernimmt daher die Funktion einer Vielzahl an konventionellen Mosaiksteinchen, wobei das Mosaiksegment wie ein einzelnes Mosaiksteinchen gehandhabt werden kann, da es sich lediglich um ein einziges Teil handelt. Aufgrund der vorgesehenen Fugen zwischen den Mosaikstrukturelementen kann dennoch der Eindruck von vielen Mosaiksteinchen erweckt werden.According to the invention, the elements of the mosaic to be produced are not produced as individual elements, but as structural elements of a carrier plate. A mosaic segment therefore takes on the function of a large number of conventional tesserae, wherein the tessellated segment can be handled like a single tesserae, since it is only a single part. Due to the planned joints between the mosaic structural elements, the impression of many mosaic stones can still be created.
Die Mosaikstrukturelemente sind auf der Trägerplatte gruppiert, d.h. in einer vorgegebenen Reihenfolge angeordnet, und bilden das Segmentmuster (also das Muster innerhalb eines Mosaiksegments). Das Mosaiksegment wird auch als "Cluster" bezeichnet.The mosaic structural elements are grouped on the carrier plate, i.e. arranged in a predetermined order, and form the segment pattern (i.e. the pattern within a mosaic segment). The mosaic segment is also known as a "cluster".
Um einen sichtbaren Rapport der einzelnen Cluster zu verhindern, ist das Design der abgebildeten Mosaikelemente so beschaffen, dass es sich in allen Richtungen gleich homogen verlegen lässt, d.h. Es entstehen visuell immer neue Anordnungen der Mosaike. Durch die spätere Verfugung der Cluster sind keine Anfänge und -enden der Cluster mehr sichtbar. Die Mosaikstrukturelemente bilden Erhebungen. Der Zwischenraum (Fuge) zwischen den Mosaikstrukturelementen wird durch die Trägerplatte begrenzt. Die Breite (kleinste Ausdehnung parallel zur Trägerplattenebene) der Mosaikstrukturelemente beträgt vorzugsweise weniger als 2 cm. Der Abstand benachbarter Mosaikstrukturelemente ist vorzugsweise kleiner als die Breite der Mosaikstrukturelemente, insbesondere kleiner 1/10 der Breite der Mosaikstrukturelemente.In order to prevent a visible repeat of the individual clusters, the design of the mosaic elements shown is such that it can be laid homogeneously in all directions, ie the mosaics are visually arranged in new ways. As the clusters are later grouted, the beginnings and ends of the clusters are no longer visible. The mosaic structural elements form elevations. The space (joint) between the mosaic structural elements is limited by the carrier plate. The width (smallest dimension parallel to the plane of the carrier plate) of the mosaic structure elements is preferably less than 2 cm. The distance between adjacent mosaic structure elements is preferably smaller than the width of the mosaic structure elements, in particular less than 1/10 of the width of the mosaic structure elements.
In einer bevorzugten Ausführungsform weisen die Mosaikstrukturelemente in der Aufsicht (Sicht senkrecht zur Trägerplattenebene) abgerundeten Konturen, bspw. rund oder länglich mit abgerundeten Ecken oder organische Formen, z.B. kieselsteinähnlich. Die abgerundeten Konturen ermöglichen das serielle, transparente glasieren der Mosaikelemente. Aufgrund der abgerundeten Form kann die Glasur komplett um die Mosaikstrukturelemente ausfließen. Darüber hinaus lassen sich die abgerundeten Elemente später durch die Handwerker präziser ausfugen. Prinzipiell können aber beliebige Formen realisiert werden.In a preferred embodiment, the mosaic structure elements have rounded contours in plan view (view perpendicular to the plane of the carrier plate), for example round or elongated with rounded corners or organic shapes, for example pebble-like. The rounded contours enable serial, transparent glazing of the mosaic elements. Due to the rounded shape, the glaze can flow out completely around the mosaic structure elements. In addition, the rounded elements can later be grouted more precisely by the craftsmen. In principle, however, any shape can be implemented.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Mosaiksegments ist die Trägerplatte aus Oxidkeramik, insbesondere aus Zirkonoxid ZrO2 oder Aluminiumoxid Al2O3, oder Silikatkeramik. gefertigt. Derartige Presskeramikteile werden in der Dentaltechnik für Kronen und Brücken verwendet [3] und können als werkzeugfallende Teile mit einer hohen Präzision hergestellt werden.In a particularly preferred embodiment of the mosaic segment according to the invention, the carrier plate is made of oxide ceramic, in particular made of zirconium oxide ZrO2 or aluminum oxide Al2O3, or silicate ceramic. manufactured. Press ceramic parts of this type are used in dental technology for crowns and bridges [3] and can be manufactured with a high degree of precision as parts off the tool.
Um das Gewicht des Mosaiksegments zu verringern, ist es vorteilhaft, wenn die Trägerplatte zwischen den Mosaikstrukturelementen mit Bohrungen versehen ist. Darüber hinaus bieten die Bohrungen die Möglichkeit, das Mosaiksegment von hinten zu beleuchten, wodurch leuchtende Mosaikbilder erzeugt werden können.In order to reduce the weight of the mosaic segment, it is advantageous if the carrier plate is provided with bores between the mosaic structural elements. In addition, the boreholes offer the possibility of illuminating the mosaic segment from behind, which means that luminous mosaic images can be generated.
Die Mosaikstrukturelemente des erfindungsgemäßen Mosaiksegments sind vorzugsweise mit einer Glasur versehen, wobei die glasierten Mosaikstrukturelemente eine Bombierung aufweisen. Die Bombierung wird durch eine spezielle Glasurtechnik bewirkt, die vorzugsweise durch Edelstahlschablonen maschinell aufgetragen wird, und dient dazu einen Glanz-/Leuchteffekt zu erzeugen, da durch die Bombierung einfallendes Licht durch die Oberfläche bis auf den reinweißen Grund der Mosaikstrukturelemente fällt und durch die Glasur hindurch zurückreflektiert wird. Die Bombierung verhindert zudem aufgrund der geringen Auflagefläche bei Kontakt mit einem Gegenstand tiefgreifende und sichtbare Kratzer. Das erfindungsgemäße Mosaiksegment weist daher eine hohe Kratzfestigkeit auf.The mosaic structural elements of the mosaic segment according to the invention are preferably provided with a glaze, the glazed mosaic structural elements having a crown. The crowning is brought about by a special glaze technique, which is preferably applied by machine using stainless steel stencils, and is used to create a glossy / luminous effect, since light falling through the crowning falls through the surface to the pure white background of the mosaic structural elements and through the glaze is reflected back. Due to the small contact area, the camber also prevents profound and visible effects when it comes into contact with an object Scratch. The mosaic segment according to the invention therefore has a high level of scratch resistance.
Vorzugsweise handelt es sich bei der Glasur um eine opake, also lichtundurchlässige Glasur, insbesondere um eine weiße oder schwarze opake Glasur.The glaze is preferably an opaque, that is to say light-impermeable, glaze, in particular a white or black opaque glaze.
Das erfindungsgemäße Mosaik umfasst eine Vielzahl an zusammengefügten zuvor beschriebenen Mosaiksegmenten. Die Fugen zwischen den Mosaikstrukturelementen sind zumindest teilweise mit einer Fugenmasse gefüllt. Verfugt werden dabei sowohl die Fugen zwischen den Mosaikstrukturelementen innerhalb eines Mosaiksegments als auch die Fugen zwischen den Mosaikstrukturelementen benachbarter Mosaiksegmente.The mosaic according to the invention comprises a multiplicity of previously described mosaic segments joined together. The joints between the mosaic structural elements are at least partially filled with a joint compound. Both the joints between the mosaic structure elements within a mosaic segment and the joints between the mosaic structure elements of adjacent mosaic segments are grouted.
Da die Elemente des erfindungsgemäßen Mosaiks nicht als Einzelelemente gefertigt sind, sondern als Strukturelemente einer Trägerplatte, die eine Vielzahl an Strukturelementen umfasst, können sehr kleine Strukturelemente mit vergleichsweise geringem Aufwand hergestellt werden. Die Strukturelemente des erfindungsgemäßen Mosaiksegments sind vorzugsweise kleiner als 1 cm, insbesondere 0,5 cm oder kleiner. Dies ermöglicht es, hochaufgelöste Mosaikbilder zu erstellen, beispielsweise von Portraits, so dass die Persönlichkeitsmerkmale der dargestellten Person nicht verloren gehen.Since the elements of the mosaic according to the invention are not manufactured as individual elements, but rather as structural elements of a carrier plate which comprises a large number of structural elements, very small structural elements can be produced with comparatively little effort. The structural elements of the mosaic segment according to the invention are preferably smaller than 1 cm, in particular 0.5 cm or smaller. This makes it possible to create high-resolution mosaic images, for example of portraits, so that the personality traits of the person depicted are not lost.
Um ein einheitliches Gesamtmuster, insbesondere ohne Rapport, zu erhalten, ist es vorteilhaft, wenn benachbarte Mosaiksegmente jeweils mit 90° Kantendrehung gegeneinander verdreht angeordnet sind. Dazu sind die Mosaiksegmente vorzugsweise quadratisch.In order to obtain a uniform overall pattern, in particular without a repeat, it is advantageous if adjacent mosaic segments are each arranged rotated with respect to one another with an edge rotation of 90 °. For this purpose, the mosaic segments are preferably square.
Bei einer speziell Ausführungsform des erfindungsgemäßen Mosaiks sind die Fugen zwischen den Mosaikstrukturelementen zumindest teilweise mit einer selbstilluminierenden Fugenmasse gefüllt. Unter "selbstilluminierend" wird insbesondere phosphoreszierend verstanden. In Kombination mit einer perforierten Trägerplatte kann somit der Eindruck erweckt werden, dass die Mosaikstrukturelemente auf einer leuchtenden Fläche aufgebracht sind.In a special embodiment of the mosaic according to the invention, the joints between the mosaic structural elements are at least partially filled with a self-illuminating joint compound. “Self-illuminating” is understood to mean, in particular, phosphorescent. In combination with a perforated carrier plate, the impression can be created that the mosaic structure elements are applied to a luminous surface.
Die erfindungsgemäßen Mosaiksegmente werden vorzugsweise zur Verkleidung einer Interieurwand oder einer Bordwand eines Schiffs, insbesondere einer Yacht, verwendet. Darüber hinaus können die erfindungsgemäßen Mosaiksegmente zur Verkleidung von Zimmerwänden, Flugzeugwänden, Möbeln etc. verwendet werden.The mosaic segments according to the invention are preferably used to cover an interior wall or a side wall of a ship, in particular a yacht. In addition, the mosaic segments according to the invention can be used to cover room walls, aircraft walls, furniture, etc.
Die Erfindung betrifft auch ein Verfahren zum Bedrucken eines Mosaiksegments mit einem Zielmotiv, wobei das Mosaiksegment eine Trägerplatte und eine Vielzahl an in einem Segmentmuster angeordneten Mosaikstrukturelementen umfasst, wobei Trägerplatte und Mosaikstrukturelemente als einstückiges Presskeramikteil ausgebildet sind. Das erfindungsgemäß Verfahren zum Bedrucken eines Mosaiksegments umfasst folgende Verfahrensschritte:
- a) Bereitstellung von abgespeicherten Farbverteilungen, wobei die Farbverteilungen erzeugt wurden durch:
- a.a.i. Herstellen eines Mosaiksegment-Dummies, wobei der Mosaiksegment-Dummy eine Dummy-Trägerplatte mit Dummy-Mosaikstrukturelementen umfasst, wobei die Dummy-Mosaikstrukturelemente in demselben Segmentmuster angeordnet sind wie die Mosaikstrukturelemente des Mosaiksegments;
- a.a.ii. Kolorieren der Mosaiksegment-Dummies, wobei jedes Dummy-Mosaikstrukturelement eine charakteristische Farbverteilung erhält;
- a.a.iii. digitales Ablichten der kolorierten Mosaiksegment-Dummies, wobei jede Farbverteilung der Dummy-Mosaikstrukturelemente in einem Speicher abgelegt wird;
- b) Erstellung eines Gesamtmusters durch virtuelles Zusammenfügen von einer vorgegebenen Anzahl an Segmentmustern mittels einer Software;
- c) virtuelles Aufteilen des Zielmotivs in Mosaikstrukturelement-Bereiche durch Überlagerung des Zielmotivs mit dem Gesamtmuster, wobei jeder Mosaikstrukturelement-Bereich ein Mosaikstrukturelement des Mosaiksegments repräsentiert;
- d) Zuweisen einer der abgespeicherten Farbverteilungen zu jeweils einem der Mosaikstrukturelement-Bereiche;
- e) Farbauftrag auf die Mosaikstrukturelemente mit denjenigen Farbverteilungen, die den Mosaikstrukturelement-Bereichen zugeordnet wurden, welche die jeweiligen Mosaikstrukturelemente repräsentieren.
- a) Provision of stored color distributions, whereby the color distributions were generated by:
- aai producing a mosaic segment dummy, the mosaic segment dummy comprising a dummy carrier plate with dummy mosaic structure elements, the dummy mosaic structure elements being arranged in the same segment pattern as the mosaic structure elements of the mosaic segment;
- aaii. Coloring the mosaic segment dummies, each dummy mosaic structure element being given a characteristic color distribution;
- aaiii. digital imaging of the colored mosaic segment dummies, each color distribution of the dummy mosaic structure elements being stored in a memory;
- b) Creation of an overall pattern by virtually assembling a predetermined number of segment patterns by means of software;
- c) virtually dividing the target motif into mosaic structure element areas by superimposing the target motif with the overall pattern, each mosaic structure element area representing a mosaic structure element of the mosaic segment;
- d) assigning one of the stored color distributions to one of the mosaic structure element areas;
- e) Applying paint to the mosaic structural elements with those color distributions which were assigned to the mosaic structural element areas which represent the respective mosaic structural elements.
Die Dummy-Mosaikstrukturelemente des in Schritt a) hergestellten Mosaiksegment-Dummies sind in demselben Segmentmuster angeordnet sind wie die Mosaikstrukturelemente des Mosaiksegments, d.h. die geometrische Anordnung (Ausrichtungen der Elemente zueinander) und die Proportionen (Länge/Breite/Abstände) der Dummy-Mosaikstrukturelemente entsprechen der geometrischen Anordnung und den Proportionen der entsprechenden Mosaikstrukturelemente des Mosaiksegments. Die Größe der Mosaikstrukturelemente kann sich jedoch von der der Dummy-Mosaikstrukturelemente unterscheiden. Dies ermöglicht eine Flexibilität in der Wahl des für das Mosaiksegment-Dummies zu verwendenden Materials. So kann für den Mosaiksegment-Dummy beispielsweise ein Material mit einem höheren oder geringeren Materialschwund verwendet werden als für das Mosaiksegment. Die Höhe der Dummy-Mosaikstrukturelemente ist vorzugsweise kleiner als Höhe der Mosaikstrukturelemente des Mosaiksegments. Dies ermöglicht ein einfaches Kolorieren. Vorzugsweise beträgt die Höhe der Dummy-Mosaikstrukturelemente gleich dem Höhenunterschied zwischen Mosaikstrukturelementen und Fugenmasse bei einem fertig ausgefugten Mosaiksegment.The dummy mosaic structure elements of the mosaic segment dummy produced in step a) are arranged in the same segment pattern as the mosaic structure elements of the mosaic segment, ie the geometric arrangement (alignment of the elements to one another) and the proportions (length / width / spacing) of the dummy mosaic structure elements correspond the geometric arrangement and proportions of the corresponding mosaic structural elements of the mosaic segment. However, the size of the mosaic structure elements may differ from that of the dummy mosaic structure elements. This allows flexibility in the choice of material to be used for the mosaic segment dummies. For example, a material with a higher or lower material shrinkage can be used for the mosaic segment dummy than for the mosaic segment. The height of the dummy mosaic structure elements is preferably smaller than the height of the mosaic structure elements of the mosaic segment. This enables easy coloring. The height of the dummy mosaic structure elements is preferably equal to the height difference between the mosaic structure elements and the joint compound in a fully grouted mosaic segment.
Vorzugsweise erfolgt das Kolorieren in Schritt b) durch Auftragen einer Glasur, insbesondere einer Keramik-Glasur. Beim Kolorieren erhalten die Dummy-Mosaikstrukturelemente eine individuelle Farbverteilung. Vorzugsweise wird jedes Dummy-Mosaikstrukturelement in einem bestimmten Farbton oder mit einer Kombination aus ähnlichen Farbtönen vorzugsweise von Hand koloriert.The coloring in step b) is preferably carried out by applying a glaze, in particular a ceramic glaze. When coloring, the dummy mosaic structure elements are given an individual color distribution. Each dummy mosaic structure element is preferably colored in a specific color shade or with a combination of similar color shades, preferably by hand.
Dadurch kommen handwerkliche Ausprägungen zum Vorschein. Deshalb können sich innerhalb eines Dummy-Mosaikstrukturelements insbesondere Helligkeit und Farbsättigung ändern.As a result, craftsmanship comes to the fore. Therefore, brightness and color saturation in particular can change within a dummy mosaic structure element.
Das digitale Ablichten in Schritt c) kann durch Fotografieren oder Einscannen erfolgen. Vorzugsweise erhält jede in Schritt c) abgespeicherte Farbverteilung einen individuellen Farbcode, der den jeweiligen Mosaikstrukturelement-Bereichen zugewiesenen werden kann. Die entsprechenden Farbcodes werden dann zusammen mit Informationen, die das jeweilige Mosaikstrukturelement identifizieren, einer Druckeranlage übermittelt.The digital imaging in step c) can take place by photographing or scanning. Each color distribution stored in step c) preferably receives an individual color code which can be assigned to the respective mosaic structure element areas. The corresponding color codes are then transmitted to a printer system together with information that identifies the respective mosaic structure element.
Die Erstellung des Gesamtmusters in Schritt d) kann durch eine 2-dimensionale Anordnung von jeweils um 90° gegeneinander verdrehten Segmentmustern erfolgen. Die Größe des Gesamtmusters entspricht der Größe des Zielmotivs.The creation of the overall pattern in step d) can take place by means of a 2-dimensional arrangement of segment patterns each rotated by 90 ° in relation to one another. The size of the overall pattern corresponds to the size of the target motif.
In Schritt e) wird das Zielmotiv entsprechend den Mosaiksegmenten des Gesamtmusters aufgeteilt, so dass jedem Mosaikstrukturelement des Gesamtmusters ein Mosaikstrukturelement-Bereich des Zielmotivs zugeordnet wird.In step e) the target motif is divided according to the mosaic segments of the overall pattern, so that a mosaic structure element area of the target motif is assigned to each mosaic structure element of the overall pattern.
Die in den Mosaikstrukturelement-Bereichen vorhandenen Färbungen werden in Schritt f) denjenigen abgespeicherten Farbverteilungen zugewiesen, die den realen Färbungen der entsprechenden Mosaikstrukturelement-Bereiche des Zielmotivs am nächsten kommen.The colorations present in the mosaic structure element areas are assigned in step f) to those stored color distributions which come closest to the real colorations of the corresponding mosaic structure element areas of the target motif.
Der Farbauftrag auf die Mosaikstrukturelemente in Schritt g) erfolgt vorzugsweise mittels Pinseln oder Airbrush.The application of paint to the mosaic structural elements in step g) is preferably carried out by means of brushes or airbrushes.
Vorzugsweise erfolgt in Schritt b) das Kolorieren der Mosaiksegment-Dummies in Handarbeit. Durch das Auftragen der Farbe in Handarbeit ergibt sich eine einzigartige Farbverteilung für jedes Mosaikstrukturelement. Mit dem erfindungsgemäßen Verfahren kann also einerseits das Bedrucken maschinell erfolgen, andererseits wird eine Farbverteilung realisiert, die derjenigen einer Handbemalung entspricht. Auf diese Weise können auf vergleichsweise günstige Art und Weise hochwertige Mosaike mit einer individuellen Charakteristik hergestellt werden.The mosaic segment dummies are preferably colored by hand in step b). By applying the color by hand, there is a unique color distribution for each mosaic structure element. With the method according to the invention, on the one hand, printing can be done by machine, and on the other hand, a color distribution is realized that corresponds to that of hand painting. In this way, high-quality mosaics with individual characteristics can be produced in a comparatively inexpensive manner.
Zur Herstellung der Mosaiksegment-Dummies und der Mosaiksegmente können unterschiedliche Materialien verwendet werden. Während für die Mosaiksegmente, die für das zu erstellende Mosaik verwendet werden, vorzugsweise Presskeramik verwendet wird, um den Schwund nach dem Brennen zu minimieren, kann für die Mosaiksegment-Dummies ein einfacher verarbeitbares Material verwendet werden, da es hier lediglich auf die Proportionen der Mosaikstrukturelemente zueinander ankommt.Different materials can be used to produce the mosaic segment dummies and the mosaic segments. While pressed ceramic is preferably used for the mosaic segments that are used for the mosaic to be created in order to minimize shrinkage after firing, a more easily processable material can be used for the mosaic segment dummies, since here it only depends on the proportions of the mosaic structural elements to each other.
Vorzugsweise werden die Mosaiksegment-Dummies aus giessfähigem oder pastösem Porzellan gefertigt (wegen der Unmöglichkeit der Entformung als ganzer Cluster sind hier die Fugen gefüllt). Porzellan ist als Material für die Mosaikelement-Dummies ideal, da es als Gießmasse erhältlich ist und die perfekte Konsistenz zum Glasieren von Hand aufweist. Die Dummies aus gießfähigem Porzellan haben alle Eigenschaften des klassischen "Geschirr-Porzellan". In der traditionellen Handmalerei wirkt sich das auf die Aufnahme der Glasuren in die Oberfläche aus - es kann deutlich präziser und damit authentisch gearbeitet werden.The mosaic segment dummies are preferably made of pourable or paste-like porcelain (because of the impossibility of demolding as a whole cluster, the joints are filled here). Porcelain is ideal as a material for the mosaic element dummies, as it is available as a casting compound and has the perfect consistency for glazing by hand. The dummies made of castable porcelain have all the properties of the classic "crockery porcelain". In traditional hand painting, this affects the way the glazes are absorbed into the surface - work can be done much more precisely and therefore authentically.
Die Erfindung betrifft auch ein Verfahren zur Herstellung eines zuvor oben beschriebenen Mosaiksegments mit folgende Verfahrensschritten:
- Herstellung einer einteiligen strukturierten Trägerplatte mit einer Oberflächenstruktur, die eine Vielzahl an Mosaikstrukturelementen umfasst, die so gruppiert sind, dass zwischen den Mosaikstrukturelementen Fugen ausgebildet sind, mittels eines Keramik-Presswerkzeugs;
- Glasieren der Mosaikstrukturelemente, wobei eine Bombierung der Mosaikstrukturelemente erzeugt wird;
- Bedrucken der Mosaikstrukturelemente.
- Production of a one-piece structured carrier plate with a surface structure comprising a plurality of mosaic structure elements which are grouped in such a way that joints are formed between the mosaic structure elements by means of a ceramic pressing tool;
- Glazing the mosaic structural elements, a crowning of the mosaic structural elements being produced;
- Printing of the mosaic structural elements.
Die Trägerplatten werden vorzugsweise mittels eines dem Spritzgussverfahren ähnlichen Verfahrens hergestellt, insbesondere mittels eines Keramikspritzgusses [4]. Hier ist der Werkzeugaufbau deutlich vereinfacht, auf eine Verwendung von Normalien wird hierbei verzichtet. Der Keramikspritzguss ermöglicht eine große Vielfalt der Formgebung bei hoher Materialqualität.The carrier plates are preferably manufactured using a method similar to injection molding, in particular using ceramic injection molding [4]. The tool structure is significantly simplified here; the use of standard parts is dispensed with. Of the Ceramic injection molding enables a great variety of shapes with high material quality.
Beim Pressen der Trägerplatten wird ein bedingter Teil eines Polymerwerkstoffs zur flüssigen Masse des Trägerplatten-Materials (z.B. Aluminiumoxid) zugegeben und dann unter hohem Druck im Werkzeug (fast schwindungsfrei) "verbacken".When the carrier plates are pressed, a certain amount of a polymer material is added to the liquid mass of the carrier plate material (e.g. aluminum oxide) and then "baked" under high pressure in the tool (almost free of shrinkage).
Um die Rauhigkeit der Oberfläche ggf zu erhöhen kann vor dem Glasieren die Oberflächen der Mosaikstrukturelemente flachgeschliffen werden. Bei entsprechender Verfahrensoptimierung kann jedoch auf ein Flachschleifen verzichtet werden.In order to increase the roughness of the surface if necessary, the surfaces of the mosaic structure elements can be ground flat before glazing. If the process is optimized accordingly, surface grinding can be dispensed with.
Vorzugsweise wird zum Bedrucken der Mosaikstrukturelemente das zuvor beschriebene Verfahren zum Bedrucken eines Mosaiksegments verwendet.The method described above for printing a mosaic segment is preferably used for printing the mosaic structural elements.
Bei einer speziellen Variante des erfindungsgemäßen Verfahrens wird zum Bedrucken ein Muffelglasur-Verfahren verwendet. Muffelglasuren lassen sich perfekt einbrennen und haben damit eine besondere Härte. Durch die Muffelglasur bekommen die Mosaike eine besondere Brillanz in der Oberfläche, da die vorgefertigten Elemente bereits transparent glasiert angeliefert werden.In a special variant of the method according to the invention, a muffle glaze method is used for printing. Muffle glazes can be burned in perfectly and are therefore particularly hard. The muffle glaze gives the mosaics a special brilliance in the surface, as the prefabricated elements are delivered with a transparent glaze.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter ausgeführten Merkmale erfindungsgemäß jeweils einzeln für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further advantages of the invention emerge from the description and the drawing. The features mentioned above and below can also be used according to the invention individually or collectively in any combination.
