The specific embodiment

According to the optical phenomena such as the diffraction of light, interference, scattering, reflection, and mutual exposure or covering by the corresponding points of the stamp of the front and back both sides that put on described board-like material relevant with the visual angle obtain according to special pattern of the present invention and color effect.

As can be seen from Figure 4, the material that is used to obtain according to effect of the present invention is to the transparent plate 1 of small part material, glass plate for example, and the thickness of described material is t.Plate 1 comprises the front 3 and the back side 2.The front 3 and the back side 2 all have printed patterns, described printed patterns has and is plane wire grating or has the form of the grating of character, described character is divided into the structure that is lines and form of slits, thereby the same degree of the main direction of the described slit of the described stamp at the described back side 2 and the direction of the slit that puts on the described stamp on described positive 3 is greater than 50%, as shown in Fig. 1 a and 1b.Fig. 4 has represented the A point of front stamp and the B point and the C point of back side stamp.If obviously the visual angle is changed, and depends on the thickness t of the material of use, the point that cooperatively interacts just changes.Under the situation at 90 degree visual angles positive 3, the light condition of some A and B cooperatively interacts, and is changed angle [alpha] when the visual angle subsequently, and when feasible visual angle with respect to positive 3 was 90 °+α, the light condition of some A and C cooperatively interacted.So, can be observed the content change that we see.

Can be individually or use the above mentioned optical phenomena that is used to reach pattern and color effect with cooperatively interacting.

For example, can use diffraction, scattering and interference by this way, promptly in described positive 3 described stamp of described plate 1, form opening diffracting or diffraction gap, consequently produce the interface between various optical environment, thereby the light of process is in the bending of the interface of different optical density, and part resolves into independent spectral color, and on ensuing light path, they are interfered mutually, and this depends on their mutual level of intimate.Light tone on the described stamp at the described back side 2 or dark-coloured interference point then influence described positive 3 and the back side 2 on the final brightness of described stamp.The laser gun of a plurality of parts on available surface of removing previous printing; perhaps by special print routine; perhaps pass through according to graphic designs in the simplest mode; the transparent grain of size corresponding to stamp thickness; for example the glass of a Fen Suiing material or Iceland spar particle are mixed in the printing-ink, produce opening diffracting.The method that produces opening diffracting can influence the decomposition of spectrum to a certain extent.Utilize and pulverize the strongest effect of glass acquisition,, thereby help higher spectral resolution because it can bring multiple refraction.

According to the present invention, put on the stamp at the back side 2 of plate 1 by the printing ink that has various reflection ray abilities by utilization, can realize the light reflection, thereby form minute surface.But also can use printing ink and in its crystal system, not only formed minute surface but also formed the pulverizing transparent material of refracting interface, for example pulverize the mixture of glass.This refracting interface both can decompose the light of arrival, can partly interfere the light of arrival again.Thereby above mentioned reflection or combined reflected effect both changed along with the visual angle, again along with the transparency of each point of described positive 3 described stamp and change.

Mutual exposure that can each point of following realization or hide.If plate 1 all has stamp on the front 3 and the back side 2, and graphic designs according to expection, described positive 3 partially transparents at least in different positions, the color of then described plate 1 always depends on the light condition of each point of stamp on the back side 2, that is, the effect of each color dot at the front 3 and the back side 2 is formed simultaneously.There is different light condition in 2 the stamp overleaf, for example adjacent one another are each is about the position of the different light rays condition of color or brightness etc., the color at the front 3 and the back side 2 changes along with the variation at visual angle simultaneously, thereby their combined effect also changes.Can use this characteristic by this way, promptly only observe from specific angle, just can see a certain configuration a little, for example a certain pattern with predetermined color.If the visual angle is changed, then pattern disappears or changes its color.

Above mentioned scheme influences pattern and color arrangement.The use of printing fire-resistant printing ink and pulverizing glass makes that to be printed material very wear-resisting.The advantage of this scheme is that it is stable, quite simple and moderate.Can easily imitate so-called metallic pigments, for example copper, silver, gold etc. according to board-like material of the present invention.

A kind of concrete application product of the present invention is represented by ceramic tile.The side length of this ceramic tile is 1-200cm, and thickness is 1-25mm, thereby the shape of ceramic tile can be rectangle, square, polygon and other shape.Under the simplest situation, as shown in Fig. 1 a, by utilizing the pattern of narrow slit 4, ceramic tile is covered by the stamp on its front 3, and the pattern of described narrow slit 4 is mainly represented by the parallel lines that utilize wear-resisting ink printing.The thickness of lines is 0.1-2mm, and spacing is 0.1-1.5mm.General rule is that size is more little, and quality is good more.But pointed size is enough to obtain expected effect.Be used for the back side 2 that ceramic tile is pasted is on the wall covered by the stamp as shown in Fig. 1 b, the film that perhaps is covered with stamp is adhered on the whole surface as the light color substrate, and the lack of alignment of character 5 is printed in this substrate, make and wherein slit 4 systems more than 50% equidirectional (forming row) perhaps make the main direction of described stamp be basically parallel to the direction of the printing slit 4 on positive 3 with on positive 3.Like this, when light is refracted, and, cause extra refraction and interference in slit 4 at the interface of different optical environment when their incident during by the glass of partially transparent at least on the stamp at the described back side 2.The mutual luminous effect of the described arrangement of the feature 5 of described slit 4 and described back side stamp causes taking place gamut (colour shift) and interferes, consequently cause the stamp on positive 3 bright unusually, described positive 3 printed layer obtains can not be by the gamut of another kind of technology acquisition.

Be higher than 50% condition by the depth of parallelism that does not keep above mentioned two kinds of directions, can locally produce different characteristics, and the direction of slit is tilted up to the angle of 30 degree.Thereby can locally obtain else interference minimum of a value and the maximum of differing more or less.In such position, they or show as the obvious increase of surperficial stamp brightness, perhaps show as on the contrary dark-coloured more, this can be effective to for shown in decorative pattern light or shade are provided.

Fig. 2 a-2c has represented such embodiment.

By this way (back explanation) in four quadrants of basic circle, arrange printed layer, in the back side of ceramic tile and positive printing one deck printed layer, all the coordinate at described basic circle be+y ,+x, described quadrant, promptly on the back side of left upper quadrant and the front stamp.The number of benchmark diameter of a circle and slit only is proportional to the size of ceramic tile.

In this example, described benchmark radius of a circle is 27mm.The back side 2 of described ceramic tile has the stamp that character 7 systems by curved form form, thus they add up to 34, as shown in Fig. 2 a.Positive 3 have the stamp of being made up of slit 6 systems that can find out among Fig. 2 b, thus they add up to 27.When sticking together each other, two systems constitute its maximum and interfere in the mutual skew in the crosspoint of character 7 and slit 6.As shown in Fig. 2 c, be arranged in the 3rd (third) at described basic circle center, described maximum is not too intensive, and their crosspoint form is for more approaching only the tilt straight line in several years of axle with respect to basic circle.On the other hand, be arranged in the 3rd of basic circle circumference, interfering maximum intensive, and their crosspoint forms the circle of radius greater than the basic circle radius.If the form with stamp on the two opposite sides face of plate glass realizes such system, then owing to the difference on character 7 and slit 6 numbers, and the cause of the effect of 6 pairs of light interference of slit, produce interference.The color effect of (if being arranged in such a way other basic circle quadrant especially equally) pattern consequently.

Interfere other similar arrangement of maximum and minimum of a value also can obtain required pattern and color effect.Represented a kind of such arrangement among Fig. 3 a-3c.The back side 2 is covered by the stamp that character 9 systems by trend curve form in wave shape form.Positive 3 have the stamp that the system by parallel slits 8 forms.If minimum of a value and peaked system are then set up in the combination back side 2 and front 3, as shown in Fig. 3 c, described system is corresponding to another color pattern.

Obtainable various other possibility patterns of the present invention have been represented among Fig. 5 a-5i.Obviously can obtain the various geometrical patterns on the Dimmable surface of one or more colors, and the three-dimensional character of this pattern, decorative pattern or have the pattern of moving image.

Commercial Application
