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 ).
