Description

  The present invention relates to an image sheet manufacturing method, an image sheet, and an image sheet material capable of displaying a clear image by either transmitted light or reflected light. These image sheets are used, for example, for advertisement or decoration.

  Conventionally, large panel photographs with a side length of several meters to 10 meters are used for advertisements on station walls, indoor walls of hotels and department stores.

  Usually, in these panel photographs, an image sheet on which an advertisement image is formed is attached to the panel, and the back of the image sheet is illuminated with a fluorescent lamp or the like. Thereby, an image looks clear by the transmitted light by illumination.

  Conventionally, it was obtained by using a photographic film in which a photosensitive emulsion is coated on both sides of a support made of a translucent film, printing the images on the photosensitive emulsion layers on both sides so as to overlap each other, and developing it. A positive photograph is used as an image sheet (Japanese Patent Laid-Open No. 59-222835).

  In such a panel photograph, an image is clearly displayed at an appropriate density by transmitted light by illumination from the back. Even when the illumination on the back is turned off, the image appears clear at an appropriate density due to the reflected light from the ambient light.

Thus, conventionally, an image sheet formed by overlapping images on both sides of a support is used.
JP 59-222835

  However, in recent years, for the purpose of improving the efficiency of advertisements, it is often performed that both ends of a long image sheet on which a plurality of images are formed are wound up by rollers and the image sheets are scrolled and displayed by rotation of the rollers. Yes.

  In the case of a scroll type display device, if a conventional image sheet is used, the front and back surfaces of the image sheet come into contact with each other and rub against each other when they are wound around a roller. There is a problem that the image becomes worn and thin, and only a thin image without contrast can be obtained.

  In that case, it is conceivable to apply a wear-resistant coating on both sides of the image sheet. In such a case, however, the weight of the image sheet increases accordingly, and the image sheet is distorted by the elongation of the image sheet due to gravity or the deflection of the rollers. This causes a problem that the image sheet is not correctly wound around the roller and the image is wrinkled.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is a method for producing an image sheet that is used for both transmitted light and reflected light, and has little image wear when used in a scroll-type display device.

[First Embodiment]
FIG. 1 is a sectional view showing a part of an image sheet 1 according to the present invention.

  In FIG. 1, the image sheet 1 includes a support 11, a first image layer 12, a film-like body 13, a second image layer 14, and a protective layer 15.

  The support 11 is made of a white or milky white translucent film made of a synthetic resin such as polyester or polypropylene. As this film, a film that is translucent or a film in which a milky white emulsion is coated on a transparent film can be used. The support 11 has a thickness of several tens to several hundreds of microns, such as 60 to 300 microns, particularly 90 to 150 microns. Desirably, the support 11 is less stretchable or has heat resistance. In particular, when a material having low stretchability due to a temperature change is used, even when the temperature rises due to, for example, a part of the image sheet 1 being exposed to sunlight, the entire image sheet 1 is distorted. Can be suppressed as much as possible. By using polyester or polyethylene terephthalate (PET) as a material, the entire support 11 has appropriate flexibility, is suitable for winding with a roller, and has good overall flatness.

  In particular, PET is lightweight, does not stretch, has good flatness, and therefore does not wrinkle, and maintains moderate flexibility without ticking even at low temperatures. Suitable as film material.

  The first image layer 12 is composed of a first image formed on one surface of the support 11. The first image layer 12 can be formed by various methods. For example, the first image is printed using opaque ink by an inkjet printer. Alternatively, printing is performed using toner with an electrophotographic printer. Alternatively, a photographic emulsion layer is formed, and the first image is exposed and developed. The first image layer 12 can be a monochrome image or a color image.

  The film-like body 13 is a thin film formed on the surface of the first image layer 12. The presence of the film-like body 13 facilitates the formation of the second image layer 14, particularly printing. When the first image layer 12 is formed by printing with ink, a film-like interface is formed on the surface by drying for several seconds to several tens of seconds after printing. It can be used as the body 13.

  Alternatively, a translucent white or milky white film may be formed as the film-like body 13 by coating (or application or printing). For example, the film-like body 13 may be formed by applying a thin ink in which a suitable amount of a pigment such as titanium white is dissolved in a solvent to the surface of the first image layer 12. Alternatively, the film-like body 13 may be formed by coating a solution containing a silica which is an inorganic filler and a binder made of a suitable synthetic resin.

  Thus, when another surface is separately coated on the surface of the image layer 12, a more effective or effective film-like body 13 can be obtained. In this case, if the film-like body 13 is formed to have a thickness of 30 μm or more, when the second image layer 14 is formed by printing on the surface, the ink penetrates deeply into the film-like body 13 and the back surface When the illumination from is performed, the image does not become thin and a clear image with contrast can be obtained. Incidentally, when the thickness of such a film-like body 13 is 10 μm or less, or about 10 to 20 μm, there is a case where the image becomes thin and sufficient contrast cannot be obtained when illumination from the back is performed. is there. Further, since the film-like body 13 has a diffusion effect and functions as a milky white diffusion plate provided between the fluorescent lamp and the like in order to make the illumination from the back surface uniform, such a diffusion plate is provided. Can be omitted.

  In the case where the film-like body 13 is separately formed, after the first image layer 12 is printed, the position of the support 11 is returned to the original position (initial position), and the support 11 is fed again to turn milky white. You may apply | coat this film | membrane. Alternatively, the film-like body 13 may be formed by applying a milky white film immediately after the formation of the first image layer 12 while printing the first image layer 12. In the latter case, it is not necessary to return the position of the support 11 to the initial printing position after the first image layer 12 is formed, so that the film-like body 13 can be easily formed in a short time. In this case, an ink tank for storing milky white ink or the like may be provided separately from the ink tank for the first image layer 12.

  The second image layer 14 includes a second image formed on the surface of the film-like body 13 so as to overlap the image of the first image layer 12. The method for forming the second image layer 14 is the same as the method for forming the first image layer 12. For example, when the first image layer 12 is formed by printing, the same image is printed in the same position. In this case, since the same image has only to be printed at the same position, positioning can be performed simply by returning the support 11 to the original position for the second printing after the first printing. The first image layer 12 and the second image layer 14 can be easily formed. In the case of forming by photographic, it is possible to form two photographic emulsion layers and to expose each photographic emulsion layer at the same time by one exposure to be sensitized.

  The protective layer 15 is made of a transparent thin film for protecting the second image layer 14. The protective layer 15 may be formed by an appropriate resin coating, or may be formed by laminating a thin resin film or by Teflon (registered trademark) processing. The presence of the protective layer 15 improves durability, reduces friction between the front surface and the back surface of the image sheet 1 when the image sheet 1 is wound around a roller, or prevents wear of the second image layer 14. be able to. When the surface of the second image layer 14 has an appropriate hardness, or when used without being wound on a roll, the protective layer 15 can be omitted.

  According to such an image sheet 1, if illumination is performed from the front (from the direction of the arrow M 1), the light passes through the protective layer 15, passes through the second image layer 14, and is absorbed by the film-like body 13. The reflected light passes through the second image layer 14 again and is observed by the observer. In this way, the second image formed on the second image layer 14 is transmitted twice to the observer's eyes, so that the same state as in the case of normal reflected light observation is obtained, and a clear image is obtained. It is done.

  Further, if illumination is performed from the back (from the direction of arrow M2), the light beam is translucent support 11, first image layer 12, film-like body 13, second image layer 14, and protective layer 15. Enters the viewer's eyes. That is, since the first image layer 12 and the second image layer 14 and the image are transmitted twice, a clear image having a contrast can be obtained as in the case of using reflected light.

  The method for manufacturing the image sheet 1 is as follows.

  A first image (first image layer 12) is formed on one surface of the support 11 by printing or the like. After printing, the film-like body 13 is formed by drying the first image. When the film-like body 13 is separately formed, the film-like body 13 is coated after the first image is dried. A second image (second image layer 14) that is the same image as the first image is formed on the surface of the dried first image or film-like body 13 by, for example, printing. Thereafter, resin coating or the like is performed on the second image as necessary.

  The image sheet 1 shown in the above embodiment can be used by being wound by a roller. By using a material with little thermal expansion and contraction as the support 11, distortion due to a local temperature difference of the image sheet 1 is reduced, and it is difficult to cause the image sheet 1 to be correctly wound around the roller. Since the protective layer 15 is provided, the image is not worn even if the front surface and the back surface of the image sheet 1 are in contact with each other. Since the thickness of the image sheet 1 can be reduced, the image sheet 1 can be easily wound up with a roller, and peeling inside does not occur. Further, since the image sheet 1 is lightweight, it is difficult for the roller to be bent or the image sheet 1 to be stretched by gravity. Therefore, wrinkles are unlikely to occur in the image sheet 1. Since the first image of the first image layer 12 and the second image of the second image layer 14 may be the same, it is easy to form these images.

Further, the image sheet 1 can be used as a panel image or a panel photograph in an expanded state without being wound around a roller.
[Second Embodiment]
FIG. 2 is a cross-sectional view showing a part of an image sheet 1B according to the second embodiment of the present invention.

  In FIG. 2, the image sheet 1 </ b> B includes a support 11, a first image layer 12 </ b> B, a film-like body 13, a second image layer 14, and a protective layer 15.

  The support 11 is made of a transparent film made of a synthetic resin such as polyester or polyethylene terephthalate. The other points are the same as those of the support 11 described above.

  The first image layer 12B includes a diffusion layer 12a and a first image portion 12b. The diffusion layer 12a is formed by coating a translucent white or milky white film. For example, as described above, a liquid in which a suitable amount of a pigment such as titanium white is dissolved in a solvent is applied. Alternatively, a solution containing silica and a binder is coated. In these cases, if the diffusion layer 12a is formed to have a thickness of 30 μm or more, the image is not thinned when illuminated from the back, and a clear image with contrast can be obtained. Further, since the diffusion layer 12a has a diffusion effect and functions as the diffusion plate described above, such a diffusion plate in the lighting device can be omitted. Further, the diffusion layer 12a has a property that ink or the like can easily penetrate.

  The first image portion 12b is formed by printing on the surface of the diffusion layer 12a. When printing is performed on the surface of the diffusion layer 12a, the ink penetrates into the diffusion layer 12a. When the thickness of the diffusion layer 12a is sufficiently thick, for example, when the thickness is 30 μm or more, the ink penetrates deeply into the diffusion layer 12a. Accordingly, when the first image portion 12b is viewed with transmitted light, the high contrast as described above can be obtained.

The film-like body 13, the second image layer 14, and the protective layer 15 are the same as those in the first embodiment. However, when the thickness of the diffusion layer 12a is increased, the film-like body 13 may be reduced. For example, when the total thickness of both is formed to be 30 μm or more, a clear image with contrast can be obtained and an appropriate diffusion effect can be obtained.
[Third Embodiment]
FIG. 3 is a cross-sectional view showing a part of an image sheet 1C according to the third embodiment of the present invention.

  In FIG. 3, the image sheet 1 </ b> C includes a support 11, an image layer 16, and a protective layer 17.

  The support 11 is the same as in the second embodiment. Here, polyethylene terephthalate is used as the support 11.

  The image layer 16 includes a diffusion layer 16a and an image portion 16b. The diffusion layer 16a and the image part 16b are substantially the same as the diffusion layer 12a and the first image part 12b of the second embodiment.

  That is, the diffusion layer 16a is formed to have a thickness of 30 μm or more by coating with titanium white or the like. The image portion 16b is formed by printing on the surface of the diffusion layer 16a. By printing on the surface of the diffusion layer 16a, the ink penetrates deeply into the diffusion layer 16a, and the image portion 16b can obtain a sufficiently high contrast as described above even when viewed with transmitted light. When the image portion 16b is viewed with reflected light, light does not enter at a depth where the ink penetrates, so that an image having an appropriate density similar to that of a normal reflected light image is obtained.

  The protective layer 17 is the same as the protective layer 15 of the second embodiment.

  According to the image sheet 1C of the third embodiment, when illumination is performed from the back, the image is not thinned, and a clear image with contrast can be obtained. Moreover, since the diffusion layer 16a has a diffusion effect, the diffusion plate in the lighting device can be omitted. Further, since the image sheet 1C has low stretchability due to temperature change, good flatness, and light weight, it is difficult for the roller to be bent or the image sheet 1C to be stretched due to gravity, and wrinkles are not easily generated. Further, even in the winter season or in a cold region, the image sheet 1C is not ticked, and a heater for heating is unnecessary. Further, since the image layer 16 is provided only on the surface on one side of the support 11, the image is not worn even if the front surface and the back surface of the image sheet 1C are in contact with each other.

Therefore, such an image sheet 1C is suitable as an image sheet used for an image scroll display device that scrolls and displays an image sheet by rotation of a roller. For example, it is suitable as an image sheet used in the image scroll display device of Japanese Patent Application No. 2003-7005 proposed by the present applicant.
[Fourth Embodiment]
4 is a cross-sectional view showing a part of an image sheet 1D according to the fourth embodiment of the present invention, FIG. 5 is a plan view showing a part of the image sheet 1D according to the fourth embodiment, and FIG. 6 is an image sheet 1D. FIG. 7 is a cross-sectional view showing a part of an image sheet 1E showing another example of the ink state.

  In FIG. 4, the image sheet 1 </ b> D includes a support 11, an image layer 18, and a protective layer 17. The image layer 18 includes a diffusion layer 18a and an image portion 18b.

  In FIG. 6, the image sheet material 10 has a support 11 and a diffusion layer 18a. That is, the image sheet 1D shown in FIG. 4 is obtained by forming the image portion 18b on the surface of the image sheet material 10 shown in FIG. 6 and then forming the protective layer 17.

  In FIG. 6, the support 11 is made of a transparent film made of a synthetic resin such as polyester or polyethylene terephthalate. That is, the same support 11 as described in the first or third embodiment is used. Therefore, there is no elasticity, low elasticity due to temperature change, good flatness, moderate flexibility without ticking even at low temperatures, high durability and stable shape and strength over a long period of time Since it is maintained, it is suitable as a film material for an image sheet for scrolling by a roller.

  The diffusion layer 18a is substantially the same as the diffusion layer 16a of the third embodiment. That is, the diffusion layer 18a is applied, for example, by applying a solution obtained by dissolving a suitable amount of a pigment such as titanium white in a solvent to the surface of the support 11 or the surface of the support 11. Alternatively, a solution containing silica and a binder is coated. The diffusion layer 18a has a property that ink easily penetrates.

  Next, as shown in FIG. 5 and FIG. 6, the image portion 18 b prints the first image 181 on the surface of the diffusion layer 18 a using ink, and after it has dried, the same 2 The second image 182 is formed by overlapping and printing.

  As is well known, each of the images 181 and 182 is constituted by dots of the respective color components C, M, Y or C, M, Y, K. Usually, one pixel of an image is constituted by three or four dots. By printing the first image 181, the ink penetrates deeply in the depth direction (vertical direction) into the diffusion layer 18 a at each dot. Each dot does not cross each other. By printing the second image 182, ink permeates the diffusion layer 18 a in the vertical direction but spreads in the horizontal direction at each dot. However, the dots do not cross each other. Or even if the dots cross each other, it is a minute part and can be ignored.

  Since the ink dries immediately, after the first printing on the surface of the image sheet material 10, the ink is dry when the image sheet material 10 is returned to the initial position, so the second printing is immediately performed. Just do it. At this time, since the image sheet material 10 does not expand and contract, the image 181 and 182 are not misaligned by two printings, and a precise and clear image portion 18b is formed.

  By forming the image portion 18b in this way, a sufficiently high contrast can be obtained as described above even when viewed with transmitted light. When the image portion 18b is viewed with reflected light, light does not enter at a depth where the ink has penetrated, and thus an image having an appropriate density same as an image for normal reflected light can be obtained.

  The protective layer 17 is the same as the protective layer 17 of the third embodiment. It is also possible to omit the protective layer 17.

  In the image sheet 1D of the fourth embodiment, the same effect as that of the image sheet 1C of the third embodiment can be obtained. Therefore, the image sheet 1D is suitable as an image sheet used for the image scroll display device as described above.

  Various cases can be considered for the state of penetration of the ink into the diffusion layer 18a. For example, in the image sheet 1E shown in FIG. 7, the first image 181 penetrates deeply over the entire region in the thickness direction of the diffusion layer 18a in each dot, and the second image 182 represents each dot. In FIG. 5, the film of the surface of the first image 181 is avoided from being dried and spreads concentrically around the surface and penetrates into the diffusion layer 18a.

  As described above, in the image sheets 1D and 1E, the image portion 18b is printed on the surface of the diffusion layer 18a using the ink jet printer, and the ink of each dot constituting the pixel of the image penetrates the diffusion layer 18a. Each of the first image layer (181) thus formed and the first image layer on the surface of the diffusion layer 18a is printed using the same ink jet printer and constitutes pixels of the same image as the first image layer. The second ink layer (182) formed on or around the thin film-like body formed on the surface of each dot is superimposed with the corresponding dot of the first image layer.

  When printing on the image sheet material 10, the image sheet material 10 is disposed in a substantially horizontal state or slightly oblique state with the diffusion layer 18a as an upper surface, and the head of the ink jet printer is positioned above or obliquely above the diffusion layer 18a. The ink is ejected from the surface close to the surface. As a result, ink of a predetermined color is sprayed from the upper side to the lower side at a position corresponding to each dot of the image, and adheres to and penetrates the surface of the diffusion layer 18a. In the first printing, the ink penetrates deeply into the diffusion layer 18a with the help of gravity, that is, the weight of the ink. Since the diffusion layer 18a is sufficiently thick, the ink penetrates deeply accordingly.

  In order to quickly dry the surface of the first image 181, that is, the ink surface, an infrared or far-infrared heater may be used or hot air may be applied. For this purpose, a heater device or a warm air device may be attached to or near the head of the ink jet printer, and the ink may be dried by these devices immediately after printing by the head.

  In the second printing, instead of returning the image sheet material 10 to the initial position, the image sheet material 10 may be fixed and the head of the ink jet printer may be returned to the initial position. In the second printing, the dots of the same image are printed at the same positions as the dots of the image printed by the first printing.

  In the above embodiment, in order to obtain a sufficiently high contrast even when an image is viewed with transmitted light, the thickness of the film-like body 13 and the diffusion layers 12a, 16a, and 18a is 30 μm or more. It was explained that it should be formed. However, if it is difficult to form only the film-like body 13 and the diffusion layers 12a, 16a, and 18a to be 30 μm or more, the total thickness of the film-like body 13 and the second image layer 14; The total thickness of the film-like body 13 and the first image layer 12, the total thickness of the diffusion layer 12a and the first image portion 12b, the total thickness of the diffusion layer 16a and the image portion 16b, or The total thickness of the diffusion layer 18a and the image portion 18b may be 30 μm or more. This is because the image layer is considered to have a diffusion effect.

  In the above embodiment, the image sheet 1, 1B, 1C, 1D, 1E or the entire image sheet material 10 or the configuration, dimensions, material, material, and the like of each part can be appropriately changed in accordance with the spirit of the present invention. .

  It can be used as an image sheet for advertisement or decoration. Moreover, it can utilize for manufacture of such an image sheet.
