Definitions

  • the present invention relates to a method of manufacturing a reproduction with luminescence effect, as well as such a reproduction.
  • tinted photoluminescent pigments only offer a limited number colors and characteristics of luminescence both in intensity and duration are limited f. In all these reproductions, one element which has a strong negative influence on the rendering of the image is the color of the luminescent product which is often yellow.
  • the aim of the present invention is to make it possible to produce, in luminescence reproduction, all types of images such as photographic images, technical drawings, artists' works, artificial images, logos, texts, wood texture effects, stones, metal, fabrics, liquids, plants, etc. These reproductions are made with very good quality of detail, sharpness, contrast and hues while allowing the luminescent image to have a very good intensity and a duration greater than that of the current state of the art.
  • a film is prepared comprising a luminescent material
  • a transparent filter is prepared to constitute a cohesion interface between the luminescent material and a surface provided with an image and to attenuate the influence of the color of the luminescent material on the rendering of the reproduction, and
  • an image is printed on at least one surface allowing the passage of light, making it transparent.
  • the advantage of the method according to the invention is that it makes it possible to print any type of image while retaining its finesse, that is to say its nuances, its tints, its details, whether the impression is in continuous tone, for example by laser, or positive or negative photographic, to obtain photographic quality, or in halftone very fine, for example in offset, or in flat, for example in screen printing.
  • the condition is that this impression is transparent and made on one or more surfaces allowing light to pass through so that the luminescent material can be reached by the light in order to optimally store the light energy, when it is a material. photoluminescent, and above all allow said energy to be restored by the light emission of the product through reproduction and said surfaces.
  • the luminescent material is, of course, preferably photoluminescent, but other materials which can be charged by other energies, such as electrical energy, can be used.
  • an adequate transparent filter must be provided. This filter can either be a film placed on the film with the luminescent product, or it can be incorporated directly into the film with the luminescent material.
  • the image is printed directly on the film with the luminescent material incorporating the filter, the surface on which the image is printed is always a surface allowing light to pass through.
  • the image is printed on a transparent support which is then affixed to the film comprising the luminescent material and on which the filter is affixed.
  • the image is also printed on a transparent support which is affixed to the film comprising the luminescent material and the filter.
  • a backscattering film is applied to the back of the film incorporating the luminescent product.
  • the image or parts of the image juxtaposed or superimposed is printed on two different surfaces allowing the light to pass thereby making it possible to obtain an effect of depth and, if necessary, an effect of relief .
  • part of the image for example the background
  • print part of the image on the filter and the other on a transparent support or even print part of the image on the film comprising the luminescent material and the filter and a transparent support.
  • printing on the support transparent could also be made on both sides, totally or partially creating a relief effect in addition to the depth. If parts of the overlay image are printed on different surfaces and in different colors depending on the viewing angle, the color overlay will also change the color of the reproduction.
  • the invention also relates to reproductions obtained by implementing the method according to the invention.
  • a luminescent effect reproduction is characterized by the fact that it is composed of a film comprising a luminescent material, a transparent filter and an image printed on at least one surface allowing light to pass through.
  • the image is printed totally or partly juxtaposed and / or superimposed on two different surfaces allowing the light to pass, thus making it possible to create an effect of depth and, where appropriate, of relief.
  • the reproduction may include a simple transparent protective screen, in particular of protection against ultraviolet radiation.
  • Figure 1 is a schematic sectional view of a reproduction according to an alternative embodiment.
  • Figure 2 is a schematic section of a reproduction according to another variant.
  • Figure 3 is a schematic sectional reproduction according to another alternative embodiment.
  • an image 2 is reproduced on a transparent support 1 and a film 4 incorporating a luminescent and more particularly photoluminescent product is applied to the support 1, either on the same side as the printed image, either of the other.
  • a filter 3 in the form of a film making it possible to attenuate the effects of the color of the photoluminescent material is inserted between the support 1 and the film 4.
  • the filter 3 can be directly incorporated into the film 4 with the photoluminescent product.
  • a backscattering film 5 is applied to the back of the film 4 with the photoluminescent product in order to optimize the photoluminous emission by the backscattering of the luminescence of the product of the photoluminescent material, the filter being either affixed to the luminescent material, or incorporated into said material.
  • the support 1 must have excellent transparency in order to allow an optimal passage of daylight and / or artificial light allowing the photoluminescent material to store energy. and, on the other hand, to allow the light emission of the photoluminescent product.
  • the support can be smooth or in relief, shiny or mat, tinted or not. Different materials can be used, in particular polypropylene and polyester. One of the factors to be taken into account in the choice of material is the quality of protection against UV radiation of the material and its compatibility with the other components of reproduction. This protection and compatibility will guarantee a good and long stability of reproduction concerning its sharpness, details, colors ...
  • the applicant has made good reproductions using supports whose thickness is between 80 and 120 microns.
  • Reproduction 2 that is to say the printed image, must have good transparency in order to allow light to pass optimally in both directions.
  • the printing mode will be chosen according to the possibilities of transparency of the inks, the fineness of the printing and the compatibility with the other components of the photoluminous reproduction.
  • a more or less tinted filter 3 having excellent transparency must be created to attenuate and correct the effects of the color of the luminescent material on the reproduction of the reproduction.
  • This filter must be of an excellent transparency so as not to alter the sharpness, the contrast, the nuances of the shades of the reproduction during the reflection of daylight and / or artificial light and of the photoluminous emission, that is to say that is, to contribute to obtaining an image as faithful as possible.
  • the transparency of the filter is also necessary to preserve the luminescence performance of photoluminous reproduction as much as possible.
  • the image can be printed directly on the filter, for example by thermal transfer or offset, or screen printing, or on the film incorporating the luminescent material and the filter.
  • the surface on which the image will be printed is perfectly homogeneous and smooth and lets in light, if only to allow the emission radiation of the luminescent material.
  • the filter affixed to the luminescent material creates a transparent surface ready to receive any type of direct print or the support on which the image has been printed or a protective screen.
  • the filter is a cohesion interface between the luminescent material and one of the elements mentioned above for a faithful rendering of the image and the attenuation of the color of the luminescent material. Creation of different techniques, filter can be considered as the application of a thin film or the insertion of the filter directly into the luminescent material.
  • the film comprising the luminescent material 4 and more precisely photoluminescent in general must be prepared in such a way that the characteristics of the luminescent pigment are not altered in order to guarantee a product having a liminous intensity, a luminescence duration and a stability in the times that are optimal.
  • the luminescent product layer can be achieved in particular by applying a luminescent film or the use of luminescent plates.
  • the application of a luminescent film with prior good preparation of the luminescent material according to the means known to those skilled in the art is often the best solution.
  • this latter solution makes it possible to obtain very good luminescent results, to vary very precisely and rationally the intensity and duration characteristics of the luminescence properties of the light layers, and to vary very rationally and precisely. the flexibility or rigidity characteristics of the luminescent layers, as well as those of luminescent effect reproductions.
  • a reliable luminescent reproduction is thus obtained both in terms of its image quality, that is to say the depth of field, the nuances, the details, etc. that of its behavior, that is to say the absence of deformation, degradation.
  • this embodiment also makes it possible to greatly attenuate the problems of mechanical stresses, that is to say the contraction, expansion during thermal shocks that the product can undergo.
  • the advantage of using a film containing the luminescent material instead of a plate is its exact adjustment to the format necessary for reproduction, thus minimizing loss and waste as much as possible.
  • the backscatter film 5 must be applied to the back of the luminescent product.
  • the backscatter film is a mirror or is tinted white, it is homogeneous and as opaque as possible. This makes it possible to optimize the light emission by the backscattering of the luminescence of the luminescent material through the various layers located above the luminescent material.
  • the backscatter film can be obtained in various ways known to those skilled in the art such as applying a film or printing a film.
  • the use of a rigid, mirror or white-tinted film offers the advantage of stiffening the luminescent reproduction.
  • an embodiment which has been found to be of good quality consists in carrying out a reproduction 2 with luminescent effect by printing the image with the laser technique, said reproduction 2 being made integral by the technique of thermofusion (hot melt) on the internal face of the transparent support 1.
  • the application of a filter 3 in the form of a thin film lying between 50 and 150 microns on the internal face of the support is also made integral by the technique of thermofusion (hot Melt) and with the application of a luminescent product in the form of '' a film of approximately 300 microns on the external face of the filter made integral also by thermofusion.
  • a backscattering film is applied by screen printing in opaque white on the outer face of the photoluminescent product.
  • the image can be printed as desired, totally or partially on one or more different surfaces such as: the two surfaces of a transparent support, the filter or the film with the luminescent material incorporating the filter.
  • Printing can be done directly, offset, laser, screen printing, "pad printing", etc. or indirect (heat transfer).
  • FIG. 3 is similar to that of FIG. 1, except that a third element, namely a backscatter film 5 is also provided.
  • Luminescent reproductions may be produced on both sides, without departing from the scope of the present invention, either by producing, according to the invention, two reproductions which are assembled back to back, or by using a luminescent film common to the two films thus allowing a saving of material and rationalization of the production.
  • the luminescent reproductions thus produced can be used in fields as manifold as varied, for example advertising, watchmaking, jewelry, tourism, games, etc. Reproduction can be conditioned in a multitude of forms, for example as a key ring, badges, T-shirt, caps, watch faces, frames, bracelets, etc.
