Description

CERAMIC TILE PROVIDED WITH A DECOR

Ceramic tiles covered with polished surfaces have a decorative decoration. The decoration is printed on the tile before providing such a tile with a glossy surface. Another known method is to provide a glossy surface with a print or to provide another glossy surface layer on the printed glossy surface. However, all the above methods may be combined with each other.

Methods are known for providing plate-like surface contact materials such as ceiling or wall panels, tiles, billboards and the like. The plate-shaped surface contact material may be reflected back by a mat or glossy surface, or may be reflected after light passes through the surface layer of the material by an object having a reflective surface provided inside the material, The mirror is provided and then reflected through the entirety of the material by the provided mirror to have a decoration using a special or unique light effect.

In addition, a method is known in which the decoration is varied according to the illumination angle and viewing angle by making a color decoration showing a rainbow effect by allowing light to pass through a system having a transparent material and a light layer.

It also creates a hidden decoration with a chromatic effect by illuminating each element having a surface relief with a series of sketches formed in a planar or embossed structure, so that when one or more images are made at a given illumination angle and perspective, It is known to have a diffraction effect.

Another known solution is that the decoration is represented by a decoration of an object having a raster, which is reproduced according to various views and which intersects with the transparent plate-shaped element and which intersects with two transparent sides and lies close to both opposite sides of the plate. Based on the interference phenomenon, there is a way to create a specific line system called the moire effect.

Patent CZ 274,488 discloses an embossed pattern decoration on an organic or inorganic glass plate. At the rear surface, the glass plate is decorated by a raster of optional elements, the front surface of the glass being decorated by the cathode portion of the raster, the raster being enlarged or reduced in the range of 0% to 15% or the raster being ± By being decorated by a raster different from the back surface raster in the range of 15%, the two rasters are optically overlapped with each other so that a three-dimensional pattern forms a three-dimensional glass ornament. The element may consist of a line, a circle, or the like. In order to enhance the effect, for example, a paint layer or frosted glass may be provided on the back surface of the glass. Optionally, the three-dimensional decoration can be combined with general planar printing or other typical decoration techniques.

However, none of the above solutions can produce multiple patterns with satisfactory quality in one optical environment arrangement and with light effects that can be made in a simple way and at a reasonable cost.

The present invention is based on optical phenomena to produce a variety of decorations on at least transparent and hard material of the glossy surface of ceramic tiles.

1 is a cross-sectional view of a ceramic tile having a decoration according to an embodiment of the present invention.

The object of the present invention is to create a variety of decorative and color effects on a solid material that is at least partially transparent and hard to the glossy surface of ceramic tiles by a simple method by optical phenomena.

The present invention relates to a ceramic tile having a decoration. The decoration is made by the light effect. The light effect is obtained by light passing through at least partially transparent material having an array of sculptures. The sculpture consists of a front printing formed at the front side of the at least partially transparent material whose front side is formed by tile gloss and a rear printing located at the rear of the rear side of the partially transparent material, the printing being between Formed by a planar raster comprising parallel lines and slits or symbols grouped within the sculpture with slits, wherein the number of sculptures of the back printing and the number of slits of the front printing differ from each other, The predominant direction is equal to or more than 50% of the direction of the slit of the front printing. Preferably, the tile gloss thickness is at least 0.1 mm.

Also, if the front printing is formed by a line raster having parallel lines and slits system, and the back printing is formed by a system of symbols grouping in a line, the lines are separated from each other by slits. .

Optionally, the front printing is formed by a line raster in which the raster comprises parallel lines and slits system and the back printing is formed by a line raster having parallel lines and slits system and the back printing is curved It may also have a system of characters formed in groups in a composition with slits in between.

Preferably the orientation of the backside printing compositions is locally diverged by an angle of 30 degrees apart from the same dominant direction by at least 50% of the compositions.

In one embodiment of the ceramic tile, the tile glossy surface is provided by front printing on the front side of the polished surface, and the back printing lying behind the back side of the tile polished surface is between the tile polished surface and the base ceramic body. It is formed on the front side of the provided bottom polished surface, and the front side of the tile polished surface is covered by the upper polished surface.

The upper gloss surface also has printing.

According to another embodiment, the tile glossy surface is provided by front printing on the front side such that the rear printing behind the back side of the tile glossy surface is between the tile glossy surface and the base ceramic body of the tile. It is provided on the front side of the bottom polished surface on which the printing is made by the wear resistant ink.

The present invention makes it possible to form a decoration on a solid material, for example, on the gloss surface of the ceramic tile or the ceramic tile, the decorations of which quality cannot be achieved by the general decoration technique. The present invention is relatively simple to implement and the cost of the product is low and therefore suitable for widespread use. When fired ink and crushed glass are used, the printed material has significant wear resistance. Thus, such materials give the possibility of using products such as, for example, tiles that are interviewed. This technical solution also makes it easy to make so-called metallic pigments with colors of copper, silver, gold and the like. This desired color is created by suitably combining the optional methods used to make the ornament.

It is also desirable to tilt locally to a 30 degree angle apart from the same dominant direction by more than 50% of the printing compositions on the back side of the tile. It is thereby possible to make somewhat localized the different maximum and minimum values of interference, which are manifested by the lightness or darkness of the front decoration that can be used to shade the represented object.

Based on optical phenomena by diffraction, interference, dispersion, and reflection of light rays, and by viewing or covering each other the corresponding points of front and back printing on at least partially transparent and rigid material of the ceramic tile with respect to the viewing angle. The specific pattern and color effect of the ceramic tile according to the design is obtained.

The material used to obtain the effect according to the invention is at least partly a transparent and hard material, a tile gloss surface 3, a plate material having a certain thickness. The tile gloss surface 3 has a printed pattern on the front and back surfaces, which pattern has a raster shape with symbols formed in groups in a flat line raster or a composition with lines and slits. Thus, the predominant direction of the slit of the back printing 6 is about 50% the same as the direction of the slit of the front printing 5. The front face of the material is the front face facing away from the ceramic base body 1 of the tile, and the back face is the back inner side of the material when the ceramic base body 1 of the tile is turned over.

It is a matter of course that the mutual cooperation points of the printings 5 and 6 change according to the change of the viewing angle and the thickness of the transparent material. Thus, for example, the light of the points located at the intersection of the line perpendicular to the front face with front printing 5 and the back face with rear printing 6 in the direction seen at an angle of 90 degrees with respect to the front face of the material. The states cooperate with each other. The view of the same point on the front face is then changed by the angle α such that this point on the front face of the material is 90 degrees + α and has a line located at the changed angle with respect to the front face of the material. The light states of the points located at the intersection of the two printings 5, 6 cooperate with each other. Thereby the angle is changed when compared with the previous viewing direction because the point of intersection of the changed line with the back printing 6 is different from the point of intersection of the line perpendicular to the line with the back printing 6.

The optical phenomena can be used individually or in combination with each other to provide a desired color representing various patterns and color effects.

For example, diffraction, dispersion and dispersion may be achieved in such a way that diffraction openings or gaps are formed in the printing 5 of the front surface 3 of the at least partially transparent material of the tile glossy surface 3 which cause interference between different optical environments. Interference can be used. Thus, the passing light rays are bent at interferences of different light densities, partially resolved into different spectral colors, and the light paths interfere around each other. The bright and dark interference points on the back printing 6 affect the brightness of the decoration. The diffraction opening corresponds to the thickness of the printings 5, 6 in the printing ink, for example by means of a laser gun removing some of the previously printed surface, or by a special printing procedure, or according to the graphic design. It can be made in the simplest way by mixing transparent particles of any size, for example particles made of ground glass or an Iceland spar. The method of making the diffraction opening can to some extent affect the dissolution of the light spectrum. The most powerful effect is obtained by using crushed glass since crushed glass causes multiple diffraction and promotes higher spectral breakdown.

According to the present invention, for example, small mirror regions can be formed by reflecting light rays by printing applied to the backside printing 6 using inks having various possibilities for reflecting light. However, it is also possible to use a mixture of ink and crushed transparent material, for example crushed glass. This mixture forms diffraction interference with the mirror surface in its crystal system. Such diffraction interference can partially interfere by breaking up the incoming light. The reaction or combined reaction effect then changes the viewing angle and transparency of the individual points of the front printing 5.

By exposing or hiding points mutually, the following effects can be obtained. If the plate has printing 5 on its front side and printing 6 on its back side, the front side of the material is formed at least partially transparent in several places, depending on the desired graphic design, and the color is always backside printing 6 Depends on the light state of the individual points. In other words, the individual color points of the printings 5, 6 affect each other at the same time. For example, a color intersection point of the colors of the front and rear printings 5 and 6 at a position where the light state is different from the rear printing 6 with respect to the individual points alternately positioned according to the color or the brightness. Changes simultaneously with the change of vision. This can be used, for example, in a way that can only change when a particular structure of points, for example a pattern, is seen at a certain angle in a predetermined color. If the viewing angle is changed, the pattern disappears or changes its color.

The solutions affect the pattern and color scheme of the printed material in such a way that conventional methods of the same quality cannot be realized in hard and at least partially transparent materials, where fireproof ink and crushed glass are used. The printed material will have significant wear resistance. This solution has the advantage of producing a stable, simple and inexpensive product. Tiles according to the present invention can easily mimic so-called metallic pigments such as copper, silver, gold and the like.

A particular application of the present invention is a glossy ceramic tile.

Such a ceramic tile may have a shape of a rectangle, a square, a pentagon, or the like. Cross sections of such ceramic tiles are shown in the accompanying drawings.

The tile consists of a base ceramic body (1). The tile glossy surface 3 has front printing 5 on the front surface. Behind the rear surface of the tile polished surface 3, the bottom polished surface 2 is printed on the bottom polished surface 2 which is located between the tile polished surface 3 and the base ceramic body 1 of the tile. ) Is provided. The front face of the tile polished surface 3 is protected by an upper polished surface 4.

The front printing 5 consists of the structure of narrow slits formed by the generally parallel lines printed by the most simply abrasion resistant ink. The thickness of the line is for example 0.1 to 2 mm and the pitch is 0.1 to 1.5 mm. It's no surprise that the smaller the dimension, the better the quality. However, dimensions are specified in order to sufficiently exhibit the desired effect. The back printing 6 is formed of confused symbols, and the structure is made such that at least 50% of the structure has the same direction as the slit structure of the front printing 5. This means that the predominant direction of the back printing 6 is substantially parallel to the slit direction of the front printing 5. In this way, the light is diffracted in the narrow slit of the front printing 5 and further diffraction and interference at the angle of incidence on the back printing 6 after it has passed through the at least partially transparent tile polished surface. This is caused by interference in different optical environments. Printing with slits of the front printing 5 and slits of the back printing 6 interfering with each other, resulting in color change and interference, resulting in a printing layer showing color change that cannot be obtained by other techniques. Unique brightness is made on the front of the.

By maintaining the state with no more than 50% parallelism in the slit direction, and by partially tilting the angle of the slit by about 30 degrees, thereby partially different interference maxima or You get the minimum. The minimum and maximum are evident at the location by the actual brightness and darkness of the front printing. This can be effectively used to express the shade of the expressed pattern.

For example, on the front and rear printing of the quadrant of the base circle with coordinates (+ y, -x) in the upper left quadrant, the printings 5, 6 arranged in the four quadrants of the base circle in the manner described below. It is possible to make The number of slits and the diameter of the base circle are only proportional to the size of the tile. The back printing 6 has a sign system in the form of a certain number of curves, which is close to the form of a third quadrant line following the center of the circle. The front printing 5 is formed by a system of number of linear slits in which the symbols of the back printing 6 are smaller than the number. When the printings 5 and 6 are put together, they create a mutually shifted interference network having a maximum at the intersection of the symbols and slits, the maximum being less dense than in a third quadrant close to the center of the base circle, Their connecting lines approach a deflected line form some distance from the axis of the base circle. On the other hand, in the third quadrant close to the environment of the base circle, the maximum interference is dense, and their connecting lines form a circle of radius larger than the radius of the base circle. When such schemes are applied as printings 5 and 6, the number of slits varies with the symbols and interference occurs due to the narrow slit used for ray interference. As a result, especially if the remaining quadrants of the basic circle are arranged in this way, the color effect of the pattern is obtained.

Other similar arrangements of interference maximums and minimums are possible to achieve the desired pattern and color effect. For example, it is possible to make a front printing 5 in the form of slits in parallel with the back printing 6 having an oblique curved sign system of the waveform. According to this type of printing structure 5, 6 it is possible to obtain geometric patterns with areas of different brightness and one or more colors, and virtual three-dimensional or decorative patterns, or patterns with pictorial motifs.

In the case of ceramic tile embodiments, it may be provided for printing according to the example of the upper gloss surface 4. If wear resistant ink is used, the upper gloss surface 4 is not necessary at all.

The present invention will find widespread use in making embellishments printed in hard and at least partially transparent materials on glossy surfaces of ceramic tiles of various patterns and colors in a simple manner and at reasonable prices.
