And the picture with the effect of luminescence to improve the quality contain film forming the fluorescent material and the filter clutch. 2 C. and 8 C.p. f-crystals, 3 ill.

The present invention relates to a method of making reproductions or copies of an image with the effect of luminescence, as well as the reproductions obtained using this method.

Currently known methods of producing reproductions or copies of those or other images with the effect of luminescence, or rather with the effect of photoluminescence, the type of image in a positive or negative shadow or images that are implemented using colored photoluminescent pigments. These two types of images with fluorescent effect is realized mainly using the following methods:

pronych printing inks on a variety of materials such as paper, fabric, plastic or metal;

using different types of printing (screen printing, tampografia", offset printing, thermal transfer, etc.,) on photoluminescent the basics of using paints that are not fluorescent;

by overlaying a transparent or opaque base, colored or colorless, perforated and/or made opaque in some selected areas, leaving the possibility of luminescence of a second luminescent bases in places perforation and/or transparent areas of the first base.

These various printing methods do not allow to obtain reproductions or copies of the image with high resolution, which could accurately be perceived visually as night and day. When using the above-mentioned printing methods it usually is quite simple drawings of geometrical character with a small number of parts and a small variety of colors. In addition, colored photoluminescent pigments have only a limited number of colors and their luminescence characteristics like intensity, and duration of action is very limited.

To all whom it shows a significant negative impact on the fidelity of image transfer, is own color fluorescent substances, which in most cases is yellow.

In the United Kingdom patent GB-A-2147542 described method, in accordance with which the image is formed directly by means of fluorescent material or, in accordance with a possible implementation option, by imposing on the luminescent material layer of opaque material.

The purpose of the present invention is to allow the reproduction or copying of all types of images with the effect of luminescence, such as photographic images, technical drawings, artwork, logos, artificial images, texts, follow the texture of wood, stone, metal, tissues, fluids, cells of plants and other These reproductions, according to the invention, are made with very high quality attention to detail, high clarity, contrast, and good color, while ensuring the possibility of obtaining a fluorescent image high intensity, lifetime exceeds the lifetime of such reproductions, made using existing state of the art in this area is e technological stages:

a) preparing a film containing the fluorescent material,

b) preparing a transparent filter that is designed to create the surface adhesion between the luminescent material and the surface, which is applied to the image, and to mitigate its own color fluorescent material on the color accuracy of the obtained reproduction or copy,

(C) be printed on at least one surface, providing the ability to pass the light, the image while maintaining its transparency.

The advantage of the method in accordance with the proposed invention is that it allows you to print any type of image, while preserving their accuracy, that is, their details and nuances, their real colors and shades, as when printing or continuous tone, for example, by laser, or a positive or negative photographic print, to obtain photographic quality, or using a very fine raster clichés, for example, with offset or silkscreen printing.

This imprint will be transparent and executed on one or more surfaces, pervious to light, so that light can reach the luminescent material, which in especiauy the possibility of energy recovery and the light emission of the fluorescent substance through the reproduction and the above-mentioned surface.

Fluorescent material in the preferred implementation is a photoluminescent material. However, there may be used and other materials that you can charge other types of energy such as electrical energy.

Since this fluorescent material has its own color, reducing the quality of reproduction, provides an appropriate transparent filter. This filter consists of either film, located on the film with a fluorescent material, or may be incorporated directly into the film.

In accordance with another variant of realization of the invention, the image printing is carried out on the filter using known means, for example by means of thermal transfer, offset printing, screen printing, etc.

In accordance with another variant of the invention the image is printed directly on the film with a luminescent material comprising a filter, and the surface on which the print image is always a surface that transmits light.

In accordance with another variant of the invention the image is printed on a transparent basis, which then is 2">

In accordance with another variant of the invention the image is also printed on a transparent basis, which is placed on the film containing the fluorescent material and the above-mentioned filter.

In accordance with another variant of realization of the invention to optimize the light emission fluorescent material impose retrodiffused film on the reverse or back side of the film, including this fluorescent material.

In accordance with another variant of the invention, the image or adjacent to each part of this image is printed on two different surfaces, pervious to light, thus allowing to provide a depth effect of the image and, if necessary, the effect of its prominence.

Indeed, in the most simple case, you can print the whole image or part thereof on both sides of some transparent basis, which then nadkalyvajut on film luminescent material, and the pre-filter placed on the film or inserted into the fluorescent material.

You can also print some portion of an image, for example, its background, with said filter, and the rest of the film, containing fluorescent material and the above-mentioned filter, and the other part of this image on a transparent basis. In this latter case the mark on this transparent can also be performed on its two sides completely or partially, thus creating the effect of a relief image in addition to its depth.

If superimposed on each part of the image printed on different surfaces and in different colors as a function of angle, overprinting will also change the color of the reproduction.

The invention also concerns the actual reproductions or copies obtained using a method in accordance with the invention.

Reproduction or copy of the image with the effect of luminescence differs in that it consists of a film containing a fluorescent material, a transparent filter and image printed on at least one surface that transmits light.

In accordance with another variant of realization of the invention the image is printed completely or adjacent or superimposed on other parts on two different surfaces, pervious to light, thus providing in the finally, reproduction or copy in accordance with the invention may contain a simple transparent protective screen, in particular a screen that provides protection from ultraviolet radiation.

The invention will be better understood from the following description of examples of its implementation with reference to the accompanying drawings, in which:

Fig. 1 depicts a section of a reproduction in accordance with one variant of the invention;

Fig. 2 depicts a section of a reproduction in accordance with another variant of realization of the invention;

Fig. 3 depicts a section of a reproduction in accordance with the third variant of the invention.

In the most simple implementation of the invention, the image 2 (Fig. 1) is reproduced on a transparent base 1. Film 4 including a fluorescent substance, rather photoluminescent substance placed on the base 1 or the side where the printed image or from the opposite side. The filter 3 in the form of a film, providing the possibility of weakening the influence of the color the photoluminescent material is inserted between the base 1 and the film 4.

In accordance with another in autoluminescent material.

And finally, in the most fully developed version of the invention retrodiffusion film 5 placed on the back, or rear, surface of the film 4 containing a photoluminescent material, to allow optimization of photoluminescent emission by retrodiffusion luminescence photoluminescent material, and a filter or imposed on the fluorescent material, or included in the film containing the fluorescent material.

Below is a detailed overview of the different elements used to implement the present invention.

The base 1 must have excellent transparency in order to ensure optimal transmission with one hand natural daylight and/or artificial light, allowing photoluminescent material to accumulate light energy, and on the other hand - to provide the opportunity of light emission of photoluminescent material.

The base may be smooth or textured, shiny or matte, painted in any color or no color. As the basis can be used in a variety of materials, including polypropylene and polyester materials. Odasity this material from ultraviolet radiation and its compatibility with other materials, forming this reproduction or copy of the corresponding image. Protection against ultraviolet radiation and compatibility with other materials will ensure a satisfactory and long-lasting durability of the reproduced image, and the accuracy of the transfer details, colors and so on

The applicant has implemented quite satisfactory reproduction when using foundations, whose thickness is in the range from 80 μm to 120 μm.

Picture 2, that is, the printed image must have good transparency to provide optimal light transmission in both directions.

Can be used in different printing techniques, such as laser printing, inkjet printing, offset printing, photographic printing from transparencies, etc., In each case, the printing method is selected depending on the transparency of the ink or printing ink, the required precision printing and compatibility with other components photoluminescent reproduction.

The applicant was able to obtain excellent reproductions in the case where the thickness of the imprint had a value of less than 10 microns.

It is obvious that not only the thickness of the Oh ink or printing ink and the resolution of this print.

As mentioned above, should be used in the filter 3, to a greater or lesser extent, painted and having excellent transparency, to weaken and to correct undesirable effect of intrinsic color of fluorescent material on the playback quality of reproduction. The filter must have excellent transparency, so as not to degrade the color quality, contrast, color reproduction when the reflection of natural daylight and/or artificial light and photoluminescent radiation, that is, it should promote possible a more accurate image. The transparency of the filter is also required to the extent possible to prevent characteristics of the luminescence of this photoluminescent reproduction.

Depending on the type of images and the results you want to achieve in this case, the corresponding image can be printed directly on the filter, for example, by thermal transfer or by offset or screen printing, or film containing a luminescent material and filter at the same time.

In this case, it is important codimy light only to allow radiation of fluorescent material.

Thus, the filter is applied to a fluorescent material, creates a completely transparent surface, ready to accept any type of direct printing or any basis on which the printed image, or any protective screen. The filter is a surface of the coupling between the luminescent material and one of the above elements, designed to give allegiance to the image and to reduce the influence on the image of their own color fluorescent material.

In accordance with the invention can be considered different technologies create a filter, such as imposing on the basis of a thin film or the introduction of filter directly into a fluorescent material.

The choice of the method of manufacturing a filter material for its manufacture, the degree of concentration and thickness will be determined depending on the specific image and the desired results, as well as from reflections received in the afternoon, and the effect of luminescence produced at night.

Film 4 that contains the fluorescent material, more specifically, the photoluminescent material, in the General case should be made in such a way that the e products, different optimal light intensity, optimum durability and optimum stability.

The receiving layer of fluorescent material can be realized, in particular, by applying a fluorescent film or by using special fluorescent plates. However, the imposition of a fluorescent film with pre meticulous preparation of the luminescent material and the use of methods, well known to specialists in this field of technology is the best technical solution.

It allows to obtain very good results effect of luminescence, very accurately and efficiently modify the characteristics of the intensity and duration luminescent properties and is very accurate and efficient way to modify the flexibility or rigidity of the fluorescent layers, and the characteristics of the obtained prints with fluorescent effect.

Thus, receive fluorescent reproduction, reliable and accurate in terms of image quality, i.e. the depth of the background, different nuances, details and so on, and General appearance, that is, the lack of deformation and damage.ADCI or stretching when possible thermal effects, who can test the product.

In addition, the benefits of using film containing a luminescent material, instead of a rigid plate luminescent material is in precise alignment in the format required for the production of this reproduction, thus minimizing loss and wastage of material.

And finally, on the back side of the fluorescent framework should be imposed retrodiffusion film 5. In the ideal case retrodiffusion film is a mirror or painted white, perfectly homogeneous and opaque. This allows you to optimize light emission using retrodiffusion or backscattering of the luminescence of the luminescent material through the various layers, superimposed over this material.

Retrodiffusion film can be obtained by various methods known in the art, for example by the imposition of a film or pripechatyvaem film.

In some cases, the use of sufficiently rigid film, mirrored or painted white, provides the advantage of giving a particular strength of this luminescent reproduction.

Method i.e. monitoring) reference is the use of laser technology, and reproduction 2 is rigidly associated with the technology of thermoplasty (hot Melt) with the inner surface of the transparent bases 1. The overlay filter 3 in the form of a thin film, the thickness of which has a value in the range from 50 μm to 150 μm on the inner surface of the base is also carried out with the use of technology thermoplasty, and the imposition of fluorescent material in the form of a film thickness of about 300 μm on the outer surface of the filter is also implemented using the technology of thermoplasty.

And finally, with the help of screen printing impose white opaque retrodiffusion film on the outer surface of the photoluminescent material. As indicated above, the present invention allows to realize satisfactory reproduction with photoluminescent effect.

It should be noted that, if it is desired to obtain a reproduction of the fluorescent effect is smooth and shiny or glossy appearance, you must use shiny or glossy transparent base. If you want to get smooth and matte reproduction with fluorescent effect, you should use matte transparent basis. If you want to get reproducibles on the outer surface of the transparent base, whereas on the other surface of this base is placed a filter, a fluorescent material and, if necessary, retrodiffusion film.

You can also obtain the effect of a relief or embossing by using some transparent basis with any relief or embossed on the outer surface, and in this case, the image is printed on the other surface, transmits light, for example on the other side of the transparent substrate and/or on the filter or if the filter is built into the fluorescent material, with partial or complete seal on the film 4.

Various combinations, are not beyond the scope of this invention, it is possible to get the desired effect in the manufacture of fluorescent reproduction. The image may be printed in whole or in part in one or several different surfaces, for example on two opposite surfaces of a transparent basis on the filter or on the film with a fluorescent material that contains the filter. Printing can be done directly, for example using offset printing, laser printing, screen printing, etc., or indirectly, for example, using thermal transfer izobrajeni transparent basis. In the examples of practical implementation of the invention, schematically illustrated in the accompanying drawings, showing various options for the creation of fluorescent reproductions. You can use, for example, a fully independent basis for each of the elements of reproduction (Fig. 2), or transparent base 1, picture 2, filter 3, the luminescent material 4 and/or integrated with one of these items. The base 1 and the image 2 are combined in one and the same element, whereas the filter and the luminescent material 4 are combined in another element.

Finally, an embodiment of the present invention, schematically shown in Fig. 3, similar to the variant shown in Fig. 1, with the exception of the third element provided here retrodiffusion film 5.

Reproduction with fluorescent effect can be a two-way products, while staying within the scope of the present invention, either by the manufacturer in accordance with this invention two reproductions, then joined back side with each other, either by using one common fluorescent film for two films, which saves material and, therefore am effect can be used in most rakoobraznyh areas for example, in advertising, in time production, in the manufacture of jewelry, in the tourist business in the gaming industry and so on Reproduction of this kind can be represented in various forms, for example, in the form of trinkets, badges, bracelets, caps, tea cups, etc.,
