Definitions

• Image including advertising image, photographic process intended to realize it.
• the present invention relates to images comprising at least one pigmented layer and at least one light-diffusing support layer, said image having components corresponding to zones of different luminosities.
• the present invention also relates to the method and the photographic film intended for producing such images.
• the present invention also relates to the use of such images for advertising purposes.
• the luminous advertisement is well known and in particular the use of boxes in which are placed images fixed on a translucent diffusing support, lit from the rear by a light source located inside the box. It is also known that the light intensity increases the attractiveness of such advertising on the viewer.
• the graphic designer can increase the visual impact of the components of the significant part of the image, from an advertising point of view, by drawing, colors, lighting at the time of shooting, or development.
• One can also place a light source having a particular shape (for example a bent tube) in the box, so that it will bring out with significant impact the significant part to the detriment of the non-significant components of the image, commonly called the bottom.
• the object of the invention is to provide an image with an enhanced advertising effect.
• the object of the invention is therefore to bring out certain components arbitrarily chosen by the graphic designer, as a whole, without taking into account lighting nuances or shades when shooting, compared to other components of the image arbitrarily deemed uninteresting by the graphic designer.
• the image according to the present invention is characterized by the characterizing part of claim 1.
• the present invention more particularly provides an image having greater transparency in the parts corresponding to the significant components of the image than that of the non-significant parts of the image.
• a bright advertising image is obtained in which the main theme is enhanced by a brightness at least 15% higher than the other components of the image forming part of the same advertising image.
• the main theme is therefore emphasized with much more vigor than in ordinary advertising.
• the image according to the present invention however makes it possible to do not restrict the choice of these other components to a dark, almost black background, in which the details are almost indistinguishable.
• the image manufacturing method according to the present invention consists, as defined by claim 6, in introducing a difference in transparency between the parts of the support associated with the significant components of the image and the parts of the support associated with the non-significant components of the image.
• This difference can be introduced by chemically locally modifying a support layer.
• a support layer For this purpose, it is possible to locally impregnate a support layer using a varnish or to locally print in this layer a preferably gray or white color. This can be done in particular when this layer is made of paper.
• This layer can also be a photosensitive layer.
• a judicious implementation of various known photosensitive products makes it possible to produce photographically developed layers of white color (light diffusing layers) in place of conventional black layers based on silver black.
• Such a photosensitive layer can be impressed, revealed and developed using a film film reproducing one of the groups of components of the image, then glued to a color copy of the same picture.
• Such a layer can also be stuck to a photosensitive layer (in particular color) before printing the image. The two layers are then impressed, revealed and developed successively, the color layer first, the layer intended for the staged diffusion of light second.
• Images can also be obtained according to the present invention by locally adding a support layer.
• the number of support layers associated with a first group of image components deemed significant by the graphic designer will be less than the number of support layers associated with the second group of image components deemed non-significant by the graphic designer.
• the parts of the support associated with the second group of non-significant components of the image comprise a highly transparent partially transparent layer; this layer is absent in the parts of the support associated with the first group of image components, deemed significant and important by the graphic designer.
• the delimitation between zone of the first group and zone of the second group is extremely simple and can be carried out using caches put in place manually.
• the selective treatment of the parts of the support corresponding either to the first or to the second group of components of the image can then also be done manually by chemical or mechanical processes known per se, such as film-coating, scraping, brushing, impregnation with solvents, varnishes, or any other technique of photography, serigraphy, printing or related techniques.
• a transparent layer in its mass but frosted on the surface such as for example a frosted acetate layer; behind this frosted layer is poured a layer diffusing the additional gray or white light which has the effect of annihilating the optical effect produced by the frosted surface of the previous layer.
• This additional layer is then removed locally as indicated above, so that the frosted surface of the previous layer again produces its optical effect in its exposed parts.
• Figure 1a shows the succession of layers of a conventional photographic film.
• 1 represents the pigmented layers
• 2 the weakly diffusing support layers (PVC, polyester, glass, etc.)
• 3 a highly diffusing layer.
• FIG. 1b shows a printout on paper of FIG. 1a, the last support layer of which has been locally impregnated with an oil.
• Figure 1c shows an image with a layer strongly diffusing under the non-signifying components of the image, this layer being absent under the signifying zones.
• 4 shows an additional layer used for the diffusion of light, for example a diffusing / frosted film.
• Example 1 pictured on paper.
• the screen of a screen printing device is prepared by blocking the meshes corresponding to the non-signifying areas of the image, either with a brush when the shape of the image is simple, or by tanning a layer of gelatin by photomechanical copy. .
• the screen is applied to the back of the image support using the squeegee and the counter re-squeegee of the device, a transparent fluid printing varnish can be printed through the free meshes which can be added with oil. The transparency of the significant areas of the image is increased. You can stick a second protective layer on the entire back of the support.
• a screen printing screen is prepared by covering the meshes corresponding to significant areas.
• a medium or strongly diffusing white or gray flat is printed behind the non-signifying areas of the image.
• a transparent and frosted film is pasted on at least one side of the image.
• An elastomeric film for flexographic printing composed of a flexible photopolymer tinted in white by incorporating a light-diffusing pigment bonded to a polyester support, which ensures its dimensional stability (for example of the type of CYREL plates, brand deposited by Dupont de Nemours) is impressed through a negative with a line veiling the significant and important parts of the image.
• the exposure hardens the parts subject to radiation by polymerization. Unexposed parts are removed in automatic equipment using a solvent and brushing.
• the film is then dried and placed behind the color slide film. Placed in a light box, the image formed by the slide / diffusing film sandwich produces a brighter image with significant surfaces.
• a transparent and frosted film is glued on both sides of the sandwich thus formed to avoid the vision of the light tubes in the box and to produce an optimal light diffusion.
• a highly diffusing layer (diffusing more than 15% of the incident light) is applied to the back of the slide.
• the drawing of the non-significant parts is screen printed on the diffusing layer with a solvent-resistant varnish which can dilute the highly diffusing layer.
• the parts not protected by the varnish are washed using the appropriate solvent or mechanically scraped.
• the whole is again glued by the back on a weakly diffusing layer / plate.
• the front part of the image can receive a frosted film.
• a highly diffusing layer is applied to the back of the slide.
• a photocuring varnish is poured over the diffusing layer.
• We superimpose a line film comprising the drawing of the significant parts.
• the parts of the varnish exposed to light will have hardened and protect the diffusing layer which will be attacked by a solvent suitable in places without protective varnish.
• the whole receives again over its entire surface a frosted film used for the diffusion of light.
• Example 6 transformation of a color photo on film with semi-opaque support.
• Example 7 A film tinted in white reacting to UV light is poured onto the back of a slide, such as for example a DINAMARK film of white color (Dinamark is a registered trademark of 3M). The development of this white layer is used to reproduce the non-significant parts of the image. A transparent, frosted film is added over the entire surface again on the front and on the back.
• the image of the non-significant parts of the slide is executed according to the COPYPROOF technique (Agfa Copyproof is a registered trademark of Agfa Gevaert) according to the production of COPYGROOF CCR white films and the corresponding automatic reproduction system.
• the COPYPROOF layer can be on a separate film which remains to stick on a color slide, or it can be directly cast from the factory on the back of a color slide.
• REGUPRINT is a registered trademark of Klaus Koenig KG: we stack a glass plate, an original black cardboard with the drawing of the significant parts, layer down, a glass plate and we expose the whole to UV radiation by extending the exposure to arrive at the model with the desired line and we develop the desired white image. The film is dried and coupled with the color slide on the back of the latter.
• this photosensitive layer which is part of the DIAZO products can be cast from the factory directly on the back of a color slide film.
• the technique of producing REGUPRINT films has the advantage of a sensitivity to light which is easily compatible with the requirements of manufacturing facilitated by the absence of the need for a darkroom and by its advantageous cost price.
