Description

  The present invention relates to an improvement of a printed matter including visible information such as characters, designs or pictures that can be identified by a person and a one-dimensional or two-dimensional code.

  Recently, as described above, printed materials including visible information such as characters, designs, or pictures and code information that can be photographed and read by a smartphone or the like are used in various scenes. For example, many commercial printed materials such as posters and leaflets are coded and printed with information such as a photograph of a product, explanation information, and guidance information to a notification site such as a campaign.

  The following patent document can be mentioned as an example of the prior art regarding such advertisement printed matter. Specifically, a two-dimensional code including point information is printed on a leaflet used in the advertisement promotion method and advertisement promotion system, and when the user reads the two-dimensional code using a mobile phone or the like, It is described that point information is sent from a terminal to a server of a management organization, and the point information is recorded for each user.

  However, considering the poster, the code information printed on it is not flexible in design, so even if it is a large poster, the area of such a code is small from the viewpoint of appearance . Therefore, those who want to know the information content of the code must photograph the code part with a smartphone etc. after approaching the printed matter, but such behavior is difficult in crowded exhibition halls and event venues There is.

  Many labels attached to or printed on various articles are printed by encoding manufacturing and seller management information, etc. together with character information such as product names and manufacturer names. However, when such code information is printed on the label of the article, there is a problem that the size of the label becomes large. In general, the manufacture and seller of goods also have a feeling that they do not want to print code information including such management information in a prominent manner on the label.

  The present invention has been made paying attention to the above-mentioned problem, and includes code information that can be photographed and read with a general smartphone or the like in a form that is hardly visible under normal lighting or sunlight. The purpose is that.

  The printed matter according to the present invention is a printed matter obtained by superimposing code information on visible information, and the code information transmits the visible information under normal light, while the direct reflection of light causes a retroreflective action. It appears to appear.

  In the printed matter according to the present invention, since the code information is hidden under normal light, the code information can have a large area regardless of the design and arrangement of the visible information. Also, under flash light, the code information looks bright and stands out. That is, since large-area code information appears, it is possible to read the code information by photographing the printed matter with a smartphone or the like even from a place away from the printed matter.

  In addition, if the printed matter is a label attached to or printed on an article, the code information can be included in an inconspicuous form without affecting the size of the label.

It is a top view when the printed matter made into one Embodiment of this invention is seen under normal illumination. It is a top view when the printed matter shown in FIG. 1 is seen from the light source vicinity of flash light. FIG. 2 is an exploded plan view illustrating the structure of the printed material illustrated in FIG. 1. (A), (b) is the top view and sectional drawing which show an example of a sheet | seat material, (c) is a perspective view which shows the structure of the microparticles | fine-particles contained in the sheet | seat material. (A), (b) is the top view and sectional drawing explaining an example of the sheet | seat material which the one part punched out by press work. (A), (b) is the fragmentary top view and sectional drawing which show the basic structure of the printed matter which does not use a sheet | seat material. It is a perspective view of printed matter made into other embodiments of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view when a printed material according to an embodiment of the present invention is viewed under normal illumination, and FIG. 2 is a plan view when the printed material is viewed from the vicinity of a light source of flash light.

  The printed matter 1 is a printed matter in which the code information 11 is superimposed on the visible information 10, and the code information 11 transmits the visible information 10 with normal light, while the retroreflective action when the light is directly irradiated. Appears. The printed material 1 is mainly assumed to be a general printed material such as a poster or flyer for an exhibition hall or event venue. There is no restriction on the size of the printed material 1.

  The visible information 10 is a character, a design, a picture, or the like that can be identified by a person formed by printing or handwriting on the medium 13 of the printed matter 1, and there is no particular limitation on the content or design. Moreover, the visible information 10 should just be formed with the dye, pigment, etc. which exhibit irregular reflection property, and the formation method in particular is not restrict | limited. For example, the visible information 10 can be formed by letterpress printing, intaglio printing, planographic printing, or plateless printing (inkjet).

  The code information 11 is assumed to be a general one-dimensional or two-dimensional code, but may be in a unique format. Further, the code information 11 is formed of a material that exhibits transparency that allows the visible information 10 behind the light to pass through under normal illumination light or sunlight, and that exhibits retroreflectivity with respect to strong light such as flash light. ing. A specific method for forming the code information 11 will be described later.

  Since the code information 11 exhibits transparency and retroreflectivity as described above, when the printed matter 1 is viewed under normal illumination or sunlight, the printed matter 1 looks like FIG. That is, the code information 11 is hidden and the visible information 10 is normally visible.

  This is because the light source of normal illumination or sunlight is located away from the viewer of the printed material 1, so that the irregularly reflected light from the visible information 10 is directed partially to the viewer, but the retroreflected light from the code information 11 is The reason is that it is not suitable for the viewer.

  On the other hand, when the printed material 1 is viewed from the vicinity of the light source under flash light, the printed material 1 looks as shown in FIG. That is, the code information 11 looks bright and stands out with the visible information 10 as a dark background.

  This is because the light source of the flash light is in the vicinity of the person who sees the printed matter 1, so that both the part of the irregular reflection component from the visible information 10 and the retroreflected light from the code information 11 are directed to the viewer. However, the reason is that the former has low luminance overall due to weak light, and the latter has high luminance due to strong light.

  Recently, many smartphones are equipped with a camera with a flash light source, and one-dimensional or two-dimensional code decoding program software is also installed. Therefore, if the printed matter 1 is flash photographed using such a smartphone, the photographed image is as shown in FIG. Since the decoding program is usually designed to determine the code information 11 based on the difference in luminance, the code information 11 can be determined for a captured image as shown in FIG.

  As described above, in the present embodiment, the visible information 10 is formed on the medium 13 by the diffusely reflective dye, pigment, and the like, and the code is made of a material that exhibits transparency and retroreflective properties on the visible information 10. Since the information 11 is formed, the following effects can be obtained.

  Since the code information 11 is hidden under normal light, the code information 11 can have a large area regardless of the design and arrangement of the visible information 10. In addition, the code information 11 looks bright and stands out under flash light. That is, since the code information 11 of a large area appears, if you have a smartphone or the like capable of flash photography, the code information 11 can be easily read by photographing the print 1 from a location away from the print 1. It is possible.

  FIG. 3 is an exploded plan view showing the structure of the printed matter shown in FIG. As shown in this figure, the basic structure of the printed matter 1 is obtained by attaching a sheet material 14 on which a pattern of code information 11 is formed in advance so that the visible information 10 overlaps the printed portion of the medium 13 on which the visible information 10 is printed in advance. It is also good.

  In the sheet material 14, the code information 11 portion may have transparency and retroreflectivity as described above, and portions other than the code information 11 may exhibit only transparency. In other words, the sheet material 14 has the base and peripheral portions of the code information 11 as a positive image. On the contrary, the code information 11 may be a negative image in which only the transparency is exhibited, and the base and the peripheral portion are both transparent and retroreflective. However, the former is considered more advantageous for photographing and reading with a smartphone or the like.

  Although not particularly illustrated, the pattern of the code information 11 is cut out from the sheet material 14 that exhibits the above-described transparency and retroreflective property as a whole, and the cut-out portion or the cut-out remaining portion is printed on the printed matter 1. You may stick. As the sheet material exhibiting transparency and retroreflectivity on the entire surface, commercially available materials can be used. For example, there is a “Light Force 1300 (registered trademark)” series handled by Maruhito Corporation.

  4A to 4C are a plan view showing an example of a sheet material, a cross-sectional view, and a perspective view showing a configuration of fine particles contained in the sheet material. The dashed-dotted line of Fig.4 (a) is a broken line.

  As shown in FIGS. 4A and 4B, the sheet material 14 is arranged regularly or randomly on the entire surface of the transparent base sheet 15 with fine particles 16 exhibiting retroreflectivity at a predetermined surface density. It has a basic structure dispersed in. An adhesive layer 17 is formed on the back surface of the base sheet 15. The fine particles 16 are fixed to the base sheet 15 with approximately half of the fine particles 16 protruding from the surface of the base sheet 15.

  As shown in FIG. 4C, the fine particles 16 may be glass beads. The size of the glass beads may not be constant. A reflective film 18 is formed on the hemisphere of glass beads by vapor deposition or the like. The metal deposition film is originally opaque, but becomes semitransparent when it is made extremely thin. The glass beads may be fixed to the base sheet 15 with the hemisphere on the side without the reflective film 18 exposed, but since there are many glass beads, the individual glass beads are fixed to the base sheet 15 in a random orientation. However, retroreflectivity is exhibited as a whole.

  The basic principle of retroreflectivity with glass beads is shown in FIG. In short, when the glass beads are viewed as a convex lens, the focal point is slightly outside the surface of the glass beads, but the focal point is closer to the surface of the glass beads as the diameter of the glass beads decreases. . Therefore, if the reflection film 18 is formed on a hemisphere of minute glass beads, parallel light incident from the opposite hemisphere is converged on the reflection film 18 by refraction, and is reflected and diffused in a direction opposite to the convergence. In the process of being refracted again by the opposite hemisphere and returning to parallel light, it becomes recursive light returning to the incident direction.

  In addition, since the base material sheet 15 is transparent, if the surface density of the glass beads is adjusted, even if the reflective film 18 is opaque, it is possible to give the sheet material 14 the desired transparency.

  FIG. 5A and FIG. 5B are a plan view and a cross-sectional view illustrating, as a modification of the sheet material, a portion in which a part of the sheet material is punched out by press working to improve transparency. A dashed line in FIG. 5A is a broken line. Elements common to FIGS. 4A to 4C are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIGS. 5A and 5B, the sheet material 14 has a large number of holes 19 formed by press working or the like. Since the hole 19 penetrates the sheet material 14, it naturally exhibits complete transparency. Therefore, even if the sheet material 14 does not exhibit transparency, desired transparency can be imparted as a whole if the shape and surface density of the holes 19 are set appropriately.

  6A and 6B are a partial plan view and a cross-sectional view showing a basic structure of a printed material in which code information is formed without using a sheet material. The dashed line in FIG. 6A is a broken line.

  As shown in FIGS. 6A and 6B, a print layer 20 including visible information 10 formed by fixing a dye, pigment, or the like exhibiting irregular reflectivity is formed on the surface of the medium 13. An adhesive 21 is applied in a shape forming the code information 11 so as to overlap the print layer 20. Fine particles 16 similar to those shown in FIG. 4C are randomly fixed to the adhesive 21 at a predetermined surface density. The mechanism in which the code information 11 of the printed matter 1 exhibits retroreflectivity is the same as in the case of FIGS.

  Although there is no special restriction | limiting in the raw material of the adhesive agent 21, It is good to use the adhesive agent of a printable type. In that case, the code information 11 is further formed by printing using the adhesive 21 on the printed material 1 on which the visible information 10 is previously formed by normal printing or the like, and fine particles 16 are sprayed and fixed thereon. If the adhesive 21 is dried, the final printed matter 1 is finished. Even if the code information 11 is a complicated two-dimensional code, it can be easily and quickly formed by printing.

  Alternatively, the code information 11 may be formed by printing using an adhesive 21 in which fine particles 16 are mixed in advance.

  4 to 6, glass beads are used as the fine particles 16 exhibiting retroreflectivity, but microprisms may be used instead. In the case of a microprism, stronger retroreflectivity can be obtained.

  Next, another embodiment of the present invention will be described with reference to FIG.

  FIG. 7 is a perspective view of a printed material according to the present embodiment. The illustrated printed matter 1 is formed as a label for a general article sold at a store or the like. Although there is no restriction | limiting in particular in the classification of articles | goods, a mug is taken as an example here. The label may be a sticker attached to the article, or may be printed directly on the article.

  For example, an article sold in a store or the like is often attached with a label printed with customer information such as a product name and price and an identification code for a POS terminal. Therefore, if the customer information is the visible information 10 and the identification information for the POS terminal is the code information 11, the size of the label can be suppressed by superimposing the code information 11 on the visible information 10.

  Some article manufacturers and distributors may include a production number, a production date, a management number, etc. in the article label. However, when the article is sold in the store, if the information on the label can be read immediately, the article may be treated as a purchase refusal from information such as the date of manufacture. However, if the production information, production date, management number, and the like are encoded to form the code information 11, the code information 11 is inconspicuous, so that the possibility of receiving such treatment is reduced.
