Definitions
- the present invention relates to a glass facing plate made of at least partially transparent material, preferably of glass, which plate is provided with a pattern or an image with a colour effect based on optical phenomena.
- hidden decorative patterns presenting colour effects by illuminating the respective element provided with a surface relief comprised of a series of traces formed of planar or relief structures and exhibiting a light diffraction effect when at a given illumination and a given view angle one or more images are generated.
- varying or hidden decorative patterns showing colour effects by illuminating rasters put on each other, whereby, one of them can be an image raster and the other a reference one, e.g. characters, whereby, they form the resulting composite image and/or letters.
- the rasters are formed by a film provided with a great number of irregular, opaque, dark image elements (reference rasters) and a film provided with a great number of dark or colour image elements on a pale colour base.
- Another known solution is represented by a decorative pattern of an object evoked in dependency on a variable angle of view which comprises a transparent or a translucent plate like element and two adjacently placed mutually crossing rasters each on one of the opposite surfaces of said element.
- the resulting system uses light interference to produce a certain resultant system of lines, the so called moire effect.
- a decorative element has also been disclosed which comprises two smaller series of motives geometrically bound, whereby, when it is illuminated in darkness by the light of the invisible spectrum an image of the first series of motives is visible, but when illuminated by light of the visible spectrum an image of the other series of motives, different from the first one, is visible.
- CZ patent No. 274,488 discloses a decor in the form of a relief pattern on a sheet of organic or inorganic glass.
- said glass sheet is decorated by a raster comprised of optional elements and the face surface is decorated either by a negative of said raster, enlarged or diminished within the range of 0 to 15 % or by another raster differing from said back surface raster by plus minus 15 %, whereby, by mutual optical overlaying of both rasters a three dimensional pattern is created which forms a three dimensional glass decor.
- the elements can consist of lines or circles, etc.
- it is possible to provide the back surface of said glass e.g. with a paint layer or by a milky glass, optionally, it is also possible to combine the three dimensional decor with a normal flat printing or with another traditional decorative technique.
- a decorative element is also known which is comprised of a base provided with a reflexive surface having a raster afixed to it, which raster is of stranded, crossed filaments. In this case a pattern is produced by the reflected light and depends on the angle of view.
- None of the above mentioned solutions makes possible in one arrangement of optical environment to create a number of patterns accompanied by light effects produced on at least partially transparent and hard materials, e.g. glass, that are of a satisfactory quality, created in a simple manner and a moderate pricing is possible.
- the present invention enables to create various decorative patterns and colour effects on at least partially transparent and hard materials, preferably on glass, in a simple manner by means of optical phenomena.
- An object of the present invention is a decorative element with a pattern or an image produced by means of light effects utilising passage of light through a plate like material, preferably a glass provided with a system of arranged formations, e.g. with lines, which element comprises a printing provided on its back rear side and on its front face side, and this at least on a part of the surfaces of said back rear side and said front face side of said plate, whereby, said element is in the form of a plate of a certain thickness, whereby said printing applied consists of a surface raster consisting of parallel lines and slits and characters grouped into formations with slits between them, whereby, the number of said formations of said back surface printing and of slits of the face printing is different and the prevailing direction of said printing formations of said back rear side is in more than 50 % identical with the direction of the slits of said printing of said front face surface.
- the decorative element plate is of thickness 1 to 25 mm.
- the printing of said front face side is formed by a system of parallel lines and slits, i.e. by a line raster, and if the printing of said rear back side is formed by a system of characters which characters are grouped into lines separated by slits from each other.
- the printing of said front face side is formed by a system of parallel lines and slits, i.e. by a line raster and if said printing of said rear back is formed by a system of characters grouped into formations having the form of lines with slits between them.
- the solution according to this invention makes possible to create decorative patterns on hard materials so as on glass etc. in a quality that can not be reached in case of a use of usual decorative techniques and the invention is by relatively simple to practice and of a moderate price for broad use.
- the printed materials are very abrasion resistant. Therefore, they provide a possibility to use the resulting product for example as facing tiles.
- This technical solution makes also simply possible to imitate also the so called metallic pigments having the colours of copper, silver or gold and others. The desired colour depends only on choosing the appropriate combination of optical methods used in production of the decorative pattern.
- the direction of printing formations on the rear back side of said plate declines by up to 30 degrees away of the of from the more then 50 % of identical prevailing direction of formations.
- Figures la and Fig. 1 b show the directions of printings applied on sides of a tile which tile represents one specific embodiment of the glass facing plate according to this invention
- Figures 2a, 2b and 2c show decorative patterns of sides and their structure in case of a tile in another specific embodiment according to the present invention
- Figures 3a, 3b and 3c show the third embodiment according to the present invention which is also a tile with printings applied on sides and their structure is also shown;
- Figure 4 shows a schematic view of a structure showing the respective images if directions of printings applied o sides according to Figures la and lb;
- Figures 5a to 5i show various decorative patterns that can be obtained using the invention.
- a special pattern and a colour effect according to this invention are obtained on the basis of such optical phenomena as are the diffraction of a light ray, interference, dispersion, reflecting and by mutual exposing or covering of the corresponding points of a printing applied on the front face and the rear back sides of said plate like material in relation to the angle of view.
- the material used to obtain the effect according to the present invention is a plate 1 of at least partially transparent material, e.g. of glass, which material has a thickness t.
- This plate 1_ comprises a front face side 3 and a back rear side 2. Both said sides 2 and 3_ are provided with a printed pattern having the form of a plane line raster or a raster with characters grouped into formations being in the form of lines and slits, whereby, the prevailing direction of said slits of said printing of said rear back side 2 is in an extent being more than 50 % identical with the direction of slits of said printing applied on said front face side 3, so as it is apparent in Figures la and lb.
- Figure 4 shows a point marked A of the front printing and points marked B and C of the back rear printing. It is apparent that so as the angle of view is changed and depending on the thickness t of the material used the mutually cooperating points change. While in the view angle 90 degrees on the front face side 3, light conditions of points A and B cooperate mutually, then when the view angle is changed by an angle ⁇ so that the view angle with regard to the front face side 3 is 90 degrees + ⁇ , the light conditions of the points A and C cooperate mutually. Therefore, a change of what we see is observed.
- optical phenomena used to reach pattern and colour effects can be applied individually or mutually cooperating.
- diffraction, dispersion and interference in such a way that in said printing of said front face side 3 of said plate 1 diffraction openings or gaps are formed, what results in creation of interfaces between various optical environments, whereby, the passing light rays bend at interfaces of different optical densities and partially decompose to individual spectral colours and in their further optical path they interfere depending on their mutual vicinity.
- the bright or the dark interference points on said printing of said rear back side 2 influence the resulting brightness of said printings on said sides 2 and 3.
- the diffraction openings can be made e.g.
- the method of making diffraction openings can exhibit an influence on break-up of light spectrum to some extent. The strongest effect is obtained by using crushed glass as it brings about multiple refraction and thereby contributes to a higher spectral break-up.
- light ray reflection can be accomplished e.g. by a printing applied to the rear back side 2 of the plate 1 using inks of various ability to reflect light, whereby, mirror surfaces are formed.
- inks of various ability to reflect light, whereby, mirror surfaces are formed.
- a mixture of inks and of a crushed transparent material, e.g. of crushed glass that forms both mirror surfaces and refractory interfaces in its crystalic system.
- Such refractory interfaces can both break up and partially interfere the in coming light rays.
- the above mentioned reflexive or combined reflexive effect then varies both with the angle of view and with the transparency of individual points of said printing of said front face side 3.
- the mutual exposing or hiding of points can be reached e.g. as follows. If the plate 1 is provided with a printing on both sides 2 and 3 and the front face side 3_ is transparent at least partially at various places according to the intended graphic design, the colour of said plate 1 always depends on light conditions of individual points of the printing on the rear back side 2, i.e. the effects of individual colour points of the front and the back sides 2 and 3 compose at the same time. At places where there are different light conditions in the printing of the rear back side 2, e.g. with regard to colour or brightness, etc., for individual points situated next to each other, the colours of the front and the rear sides 3 and 2 change simultaneously with the change of the angle of view, whereby, their composed effect changes as well. This can be used e.g. in such a way that a certain configuration of points, e.g. a pattern, is visible only if viewed from a specific angle in a pre-defined colour. If the viewing angle is changed the pattern disappears or changes its colour.
- the above mentioned solutions influence the pattern and the colour scheme.
- Use of the printed fired inks and of the crushed glass make the printed materials very abrasion resistant. It is an advantage of this solution that it is stable and rather simple and of a moderate price.
- the plates according to this invention can e.g. easily imitate the so called metallic pigments, so as copper, silver, gold, etc.
- a specific application product of this invention is represented by a glass tile.
- Such tile can have a side length of 1 to 200 cm and a thickness of 1 to 25 mm, whereby, the tile shape can be that of a rectangular, square, polygon or other.
- the tile is covered by a printing on its front face side 3 using the pattern of narrow slits 4 , represented substantially by parallel lines printed using an abrasion resistant ink.
- the lines are 0.1 to 2 mm thick with a pitch of 0.1 to 1.5 mm.
- the rear back side 2, used to stick the tiles to a wall, is covered by a printing so as shown in Fig. lb or a film covered with a printing is glued to the whole surface as a light colour base and a chaotic formation of characters 5 is printed into this base, so that more than 50 % of them are of the same direction (forms rows), as a system of slits 4_ on the front face side 3 or so that the prevailing direction of said printing is substantially parallel to the direction of the printing slits 4 on the front face side 3.
- FIGS 2a to 2c show such an embodiment.
- the tile is printed both on the back rear and the front face sides by a printing layer arranged in four quadrants of a basic circle is such a way, which is described later, both on the back rear and the front face printing of said quadrant of said basic circle with coordinates +y, +x, i.e. of the left upper quadrant.
- Diameter of the basic circle, as well as the number of slits are proportional only to the tile size.
- the radius of said basic circle is 27 mm.
- the rear back side 2 of said tile is provided with a printing consisting of a system of characters 7 in the form of curves, whereby, their total number is 34, so as it can be seen in Fig. 2a.
- the front face side 3 is provided with a printing consisting in a system of slits 6 that can be seen in Fig. 2b, whereby, their total number is 27.
- both systems form a mutually shifted interference net having its maxima in intersections of characters 7 and slits 6. As it can be seen in Fig.
- said maxima are less dense in the third which is situated at the centre of said basic circle and their junction is in the form getting near to the form of a line declined only by several angle degrees to the axis of the basic circle.
- the interference maxima are dense and their junction forms a circle of a radius which is greater then what is the one of the basic circle.
- FIG. 3a to 3c Similar other arrangement of interference maxima and minima are also possible to obtain the required pattern and colour effects.
- One of such arrangements is shown in Figures 3a to 3c.
- the rear back side 2 is covered by a printing consisting of a system of characters 9 in the form of inclined curves of a wave form.
- the face front side 3 is provided with a printing consisting of a system of parallel slits £. If they are composed a system of minima and maxima is established, so as it is shown in Fig. 3c, which system corresponds to another colour pattern.
- the present invention will find broad use in producing hard materials, preferably glass materials that are covered with applied printings.
- a broad variety of patterns and colours can be obtained by a rather simple method enabling a moderate pricing. Therefore, such products can be broadly used as facing tiles.
