Description

  The present invention is a method for producing a tactile information notation using a laser printing method for forming a tactile information notation on a plastic film with laser light, and a tactile information notation obtained by using such a laser printing method, The present invention relates to printed matter such as bags and packages. The tactile information notation here is, for example, a laminated body formed by laminating a plastic film on the surface, and on the surface film layer, information such as characters, symbols and / or figures can be read by tactile sense such as a fingertip. Means the indicated object.

Braille is one of the information transmission means for visually impaired people using tactile sense.
The standard 6-point braille system used around the world is to place point-like protrusions at a total of 6 points (2 horizontal points x 3 vertical points) in one square, and read the protrusion arrangement with the fingertip. It consists of a very simple mechanism that reads the layout by replacing it with characters.
However, with the increasing number of diabetic patients around the world in recent years, the number of people who become visually impaired after becoming older has increased. It is very difficult for such visually impaired people to memorize the relationship between the arrangement of the points and the corresponding characters. Is difficult. Furthermore, such visually impaired persons are not learning Braille, and are currently unable to use Braille.
Moreover, the misuse of a visually handicapped person can be prevented by indicating the product name in Braille on a package such as a medicine. However, since it is a sighted person who manufactures such a package, there is a problem that it is not noticed even if a wrong Braille notation is made on the package.
In addition, because Braille notation represents different characters even if the character type is different, there is a problem that even if you can read Braille in your own country, you can not read Braille in other countries, it is difficult for visually impaired people to go abroad There's a problem.

To solve the problem of difficulty in communicating information in Braille to visually impaired people who have difficulty learning Braille and their family members who are taking care of them, so that they can read sentences and words without learning Braille. Research has been made on tactile characters in which normal characters are represented by linear protrusions and dot protrusions, and tactile drawings in which maps and figures are represented by linear protrusions and dot protrusions.
Tactile characters can be read by tracing the shape of the characters with your finger without knowing Braille, so it is convenient for visually impaired people who have difficulty learning Braille but know the characters. For example, if English is written using alphabetic tactile characters, a visually handicapped person who can understand English can read the country where he / she learned Braille. In addition, tactile drawings can be read by tracing a two-dimensional shape that cannot be expressed in Braille with a finger, so it is a useful information transmission means not only for visually impaired people who have difficulty learning Braille but also for Braille users. is there.

  Since the tactile characters and the tactile figures have a structure in common with the Braille in which the protrusions are formed on the plane, it can be produced by using the same method as the Braille production.

Conventionally, as a method of providing braille for mass-produced products, a method of embossing paper or plastic film using a combination of an intaglio for braille and a relief for braille, a mold used for injection molding or sheet molding There are a method of engraving an intaglio for braille, a method of heating after printing a braille pattern with foamed ink, and the like.
Further, there is a method in which a colorless and transparent UV curable ink is raised and printed by silk screen printing, and then the UV curable ink is cured (see Patent Document 1). Since this method can display Braille on a general printed matter, the sighted person and the Braille user can obtain information from the same plane even if the sighted person cannot understand the Braille content. There is.
Although these methods are suitable for mass production, it is necessary to produce a plate, and many steps are required to produce a plate. There is a problem that it is low. Furthermore, since it is necessary to prepare a plate in advance, it is almost impossible to indicate variable information such as the date of manufacture and the serial number in Braille. Further, in the method using the engraving printing, there is a high possibility that the ink drops off, and in order to obtain a sufficient ink height at each point (each raised portion), overprinting is necessary, which is very expensive. In addition, the method using the raised printing is hardly used for packaging materials for pharmaceuticals and foods because it is difficult to apply to the plastic film.
For these reasons, there has been a problem that it is difficult to give braille directly to a package using a plastic film in which the contents are packaged and sealed. For this reason, there is almost no indication of Braille directly on plastic film packaging materials for pharmaceuticals and foods, and when Braille notation is required for plastic film, it is expensive Braille notation that uses Braille notation on adhesive tape. The only way was to apply a label.

In addition, as a simple Braille forming method, there is also a method in which a thermal head is applied to a print area to which foamed ink is applied, only the portion where the Braille is to be formed is heated with the thermal head, and foamed ink is foamed to form Braille (patent) Reference 2).
However, this method has a problem in that the braille formed by the foamed ink is exposed on the surface and is inferior in scratch resistance and water resistance. In addition, as a problem that can be said in general for products using foamed ink, the foamed ink itself is very expensive, and if the product is passed through a heating process, if unintended frictional heat or heating is applied, long-term storage at high temperatures is performed. In such a case, the non-braille part is unintentionally foamed, and there is a problem that heat resistance is inferior.
In addition, when using foamed ink, it is necessary to heat the foamed ink directly with a thermal head in order to obtain a sufficient bulge. Not only does this occur, but insufficient heating due to the adhesion of dirt easily occurs. In addition, since the foamed ink foams, a space is created between the thermal head and the foamed ink. If the thermal head becomes slightly uneven due to contamination of the thermal head, the foamed ink is heated only in the part where the thermal head is less contaminated. Since a space is generated, it was very difficult to continue uniform foaming.

In addition, there is a simple Braille forming method using a laser marker, and there is a method of expressing Braille by a ring-shaped resin pool generated around a hole opened by irradiating a scanning laser beam on a film (see Patent Document 3). ).
However, the ring-shaped protrusion around the perforated film portion has a problem in that it cannot obtain a sufficient “height” that is important for identifying points and lines.

  Also, in order to make a conventional braille notation, it is necessary to prepare a printing plate, a mold, an embossing mold, etc., and due to cost increase and technical problems, most of them are written simultaneously with Braille. Not. For this reason, there is a problem that a sighted person who cannot interpret Braille cannot assist when the Braille user cannot understand sentences and words in Braille. In particular, with the recent aging of society, there is an increase in the number of "braille users who are forced to use braille after age but are difficult to read braille". There is a problem that sighted people cannot read braille and cannot assist such braille users.

  In addition, it is very difficult to display Braille on both sides of a single substrate with conventional technology, and in order to write Braille on both sides of one page, past the backs of multiple substrates that are braille on one side. There was no choice but to make it cumbersome and expensive. In addition, there was no package that could recognize Braille from both front and back, with Braille notation on both sides.

  As described above, even when using relatively simple braille notation that expresses characters with only six points, there are many problems in the forming method and the notation object. Although it is possible to produce a tactile character or figure using a device with a large Braille device if it is expressed in a matrix like Braille, even a simple character such as an alphabet can be produced using a matrix of points. In order to express it, a space capable of forming around one hundred points per character is required, so a wide space is required for each character, which is not practical. Moreover, it is practically difficult to create a sentence using such tactile characters composed of a large number of points by hand like a Braille device. Furthermore, it is practically impossible to express various slant lines and various curvature curves with a matrix in a limited region. Therefore, tactile information notation such as tactile characters and tactile figures can be used by visually impaired persons who cannot read braille, and the visually impaired person and sighted persons can share the same information medium. Nevertheless, it is very difficult to study tactile characters and tactile figures that need to be verified by trial and error, such as tactile characters that are easy to read with the fingertips and tactile figures that are easy to follow with the fingertips. For this reason, the development of such tactile characters and tactile drawings has not progressed.

By carrying out pattern printing with a dotted line consisting of spot-like spots using a scanning laser beam capable of burning the carbon black, a gap is generated in the burned portion of the carbon black and combustion gas and combustion heat are generated. generate. At this time, the pressure in the voids is increased by the combustion gas, and the plastic film in the voids softened by the combustion heat is raised and formed into a dome shape to obtain a continuous point-like raised portion. In short, the laminate is irradiated with laser light to burn carbon pigments present in the intermediate layer, and the surface of the laminate is inflated like a balloon to form a dome-like raised portion.
For implementation, for example, using a laser marker using YVO ₄ laser light, a character or symbol drawn with a dotted line consisting of spot-like points input to the laser marker operating computer without creating a plate Alternatively, a pattern such as a figure may be output as a laser as it is, which is excellent in convenience.
The laser braille printing method according to another aspect of the present invention is a display film made of a plastic film, the display film having a non-breathable surface bonded to the support, and the bonded surface of the display film. In a laser printing region provided by applying a black ink containing carbon black to the bonding surface of the display film and / or the support in the laminated body in which the support is formed of a non-breathable surface. On the other hand, by using a scanning laser beam capable of burning the carbon black without perforating the display film and the support, by carrying out spot-like braille pattern printing from either of the both surfaces of the laminate, A gap is generated in the portion where the carbon black is burned, and combustion gas and combustion heat are generated. At this time, the pressure of the voids is increased by the combustion gas, and the plastic film in the voids softened by the combustion heat is raised and molded into a dome shape, so that point-like bumps can be obtained. Simply put, the laminated body is irradiated with laser light to burn carbon black (carbon pigment) present in the intermediate layer, and the surface of the laminated body is inflated like a balloon to form a dome-shaped raised portion (dome-shaped molded portion). Can be formed. In carrying out this method, for example, by using a laser marker (laser emitting device) using YVO ₄ laser light, the data of the braille pattern input to the laser marker operation computer without producing a plate Is reflected in the laser output as it is, and this aspect is excellent in simplicity.

In addition, the laser printing method according to one embodiment of the present invention can perform printing from both the front and back surfaces of the tactile information notation surface, and can simultaneously print on both sides with a single laser marker.
In addition, the laser braille printing method according to another aspect of the present invention can perform braille printing from both the front and back with reference to the braille notation surface. Therefore, when incorporating a laser braille printing process into a product production line that has been used in the past. There are few restrictions on laser marker installation space.

In addition, since the laser braille printing method according to another aspect of the present invention can print characters in the same manner as braille printing, it can easily print a display for sighted people together with the braille characters.

In addition, there is no need to count and interpret the number of dots as in the case of Braille, so the tactile characters and figures formed with the protruding dotted lines are smaller than the Braille dots and can be easily Can be read and tracked by touch. In addition, for example, a text in which alphabets are written in tactile characters has an advantage of being expressed in tactile characters instead of Braille, such as a visually handicapped person who can read only Braille characters from his / her home country can understand the alphabet.
The laser printing method according to one embodiment of the present invention is excellent in the ability to form a small raised portion, and can freely form a tactile character or a tactile figure with diagonal lines or curves without using a matrix. Tactile information can be displayed in space. In addition, by arranging characters and diagrams by arranging dotted lines, it is possible to form bold characters or to express a two-dimensional surface such as a company logo, pictogram, map, picture, or other figure. Furthermore, the fact that printing in a smaller space is sufficient leads to shortening of the printing time, which is not only convenient in terms of implementation, but also allows the information transmission surface to be reduced, so that the spread of tactile characters, tactile drawings, etc. The pattern of characters or figures drawn with dotted lines consisting of spot-like points input to the laser marker operation computer can be output directly to the laser without producing a plate. The time required for research on fonts and graphic representation suitable for characters can be greatly shortened, and it can contribute to the development of tactile information notation that enables visually impaired and sighted people to share the same information medium.

  Also, even if one Braille character is missing, it becomes a completely different character. However, there is no problem even if the touch character formed by the protruding dotted line lacks one point. Moreover, even if the height of the protrusion of the tactile character formed by the protrusion dotted line is lower than the height of the Braille character, the tactile character can be sufficiently recognized. For this reason, the tactile characters formed by the dotted dotted lines are more resistant to rubbing and crushing than the braille characters, and the dots are not easily missing.

In addition, the tactile information notation according to one aspect of the present invention is to display visible information such as characters or figures in a three-dimensional manner so that it can be read by the tactile sense of the fingertip, and is common to sighted persons and visually impaired persons. It can be a transmission means. Therefore, when a visually handicapped person cannot read such a tactile information notation, any sighted person can assist a visually handicapped person.
Moreover, since the laser braille printing method according to another aspect of the present invention can print characters in the same manner as braille printing, it is easy to print braille readings in the vicinity of the braille printing portion. This allows Braille users and sighted people to share information so that sighted people can read and communicate Braille content to Braille users. Can deepen the understanding of the person.

Moreover, the adhesive body with tactile information notation according to the present invention can be easily obtained using the laser printing method according to the present invention.

Moreover, in the tactile information notation according to one embodiment of the present invention in which the printing unit is not perforated, the surface of the printing unit is protected by the plastic film layer. Therefore, depending on the design of the material and configuration of the plastic film layer, it is possible to obtain a tactile information notation body that has excellent heat resistance, water resistance, oil resistance, friction resistance, hygiene, and the like and has long-term storage stability.
Moreover, in the laser braille printed matter according to one embodiment of the present invention in which the braille printed portion is not perforated, the braille printed portion is protected by the plastic film layer. Therefore, depending on the design of the material and configuration of the plastic film layer, it is possible to obtain a braille printed material having excellent heat resistance, water resistance, oil resistance, friction resistance, hygiene, etc. and having long-term storage stability.

Further, since carbon black in the printing portion burns between layers, smoke generated by laser printing does not leak to the outside, and a sanitary laser printing work environment can be provided.
Further, since the carbon black in the braille printing portion burns between the layers, if there is no perforation in the braille printing portion, smoke generated by the braille printing does not leak to the outside, and a sanitary work environment can be provided.

Moreover, since the most versatile black ink can be used as the ink containing carbon black, the cost advantage is great. Therefore, each aspect of the present invention can be applied not only to low-priced food packaging and contents packaging of pharmaceutical packaging, which has been difficult to display in Braille due to cost problems, but also includes instruction manuals, newspapers, magazines, etc. It can also be applied to disposable document prints.
In addition, if a device and software that converts input characters and figures into dotted line patterns and outputs laser light in accordance with the dotted line patterns, a dotted line pattern of letters and figures can be output as if writing text with a typewriter. Therefore, more information can be provided more quickly and an improvement in the quality of life of the visually impaired can be expected. In addition, if a device and software that outputs laser light according to the braille pattern after converting the input characters into a braille pattern, the braille pattern can be output as if writing a sentence with a typewriter. It can also be expected to improve the quality of life.

  In addition, the laser printing method and the Braille printing method according to one aspect of the present invention can be applied to most of the packaging materials conventionally used for product packaging without using a laminate using a special material or manufacturing method. Since it can be applied simply by performing printing for providing a printing area, it can be easily introduced into a commercial product.

  In addition, the laser printing method according to one embodiment of the present invention can immediately output the contents input to the computer, so that variable information can be printed, and is the same as the laser marker used in the conventional product packaging process. Alternatively, printing can be performed with the same device. Therefore, it is possible to easily describe variable information such as expiration date and expiry date, contents name, etc. with tactile information for packages such as pharmaceuticals, cosmetics, foods, chemicals, and detergents. Helps prevent misuse of visually impaired people.

In addition, tactile information can be obtained via a plastic film label (for example, an in-mold label) or a plastic film (for example, a laminated can) attached to a three-dimensional product such as a can or a bottle that has not been able to express tactile information directly. Can be printed directly.
In addition, physical properties such as water resistance, oil resistance and / or friction resistance can be applied to a structure or an object that cannot be directly laser-printed by applying the adhesive body with tactile information notation according to one embodiment of the present invention. An excellent tactile information notation unit can be provided.
In addition, three-dimensional products such as cans and bottles that could not be represented in Braille conventionally, products made of materials that could not be represented in Braille due to physical problems such as water resistance, oil resistance, friction resistance, etc. By sticking such an adhesive body with braille notation, it becomes possible to produce a braille notation excellent in physical strength.

  In addition, the Braille printing method according to one aspect of the present invention can directly carry out Braille printing on a three-dimensional product in the same manner as the date printing method in the conventional product packaging process, so that pharmaceuticals, cosmetics, foods, chemicals can be used. In addition, it is possible to easily indicate the date of use, expiration date, etc., the name of the contents, etc. in Braille on a package such as a detergent, which helps to prevent misuse of Braille users.

In addition, since the printing method according to one embodiment of the present invention can print on both sides of a single sheet (paper), the step of bonding two sheets each having a tactile information notation portion on one side back to back is provided. A double-sided tactile information notation can be obtained without the need. Moreover, since it can print on both surfaces of the heat seal part of a package body, a visually handicapped person can find a tactile information description part easily.
In addition, since the Braille printing method according to one embodiment of the present invention can perform Braille printing on both sides of a single sheet (paper), the step of bonding two sheets each having a Braille notation portion on one side is bonded back to back. A double-sided braille notation can be obtained without the need. Moreover, since braille printing can be carried out on both surfaces of the heat seal part of a package body, a braille user can find a braille notation part easily.

  Next, an embodiment of the invention will be described in detail.

  In the following description, the “tactile information notation” means an object on which information that can be acquired by tactile sense is written, and is typically configured by a convex portion (a raised portion) that can be perceived through the tactile sense. It means an object on which a tactile information pattern is formed. Here, the “tactile information pattern” means a pattern representing information that can be acquired by tactile sense, and typically, one convex portion (protruding portion) or a plurality of convex portions (protruding portions) that can be perceived through tactile sense. Part). The target that can be expressed by the “tactile information pattern” is not particularly limited as long as it is information that can be perceived by the user. For example, not only braille for the visually impaired but also letters such as alphabet that can directly transmit information Symbols and figures can also be expressed by tactile information patterns. In addition, a convex part (protrusion part) can be used directly or indirectly in order to represent specific information, and specific information may be represented by convex part (protrusion part) itself, for example, specific information Protruding portions (raised portions) may be used to form the contour, and specific information may be represented by non-convex portions (see FIG. 19 described later).

  Hereinafter, a tactile information notation (hereinafter also referred to as “Braille notation”) in which a tactile information pattern (hereinafter also referred to as “Braille pattern”) that mainly represents Braille will be described in the “first embodiment”. . A tactile information notation in which a tactile information pattern expressing characters such as alphabets other than Braille, symbols, figures and the like is formed will be described in the “second embodiment”.

  In the detailed description of the laser printing method according to the present invention, it is assumed that the laser beam irradiation to the laser printing laminate used in the present invention is basically carried out one side at a time. The tactile information notation according to the present invention is applicable not only when the tactile information notation is provided on only one side of the laminate, but also when the tactile information notation is provided on both sides of the laminate. It is also possible to perform laser printing simultaneously on both sides of the laminate using a marker. When performing laser printing on both sides of the laminate at the same time, the laminate for laser printing used in the present invention consists of display films (display layers) on both surfaces, and separately prints on the inside of both display films (both display layers). There is a need for a black ink layer in the region and a support having a laser light shielding layer between the black ink layers in both print regions.

[First Embodiment]
(Laminate for laser printing)
The laminated body shown in FIG. 1 is the basic structure of the laminated body 1 for laser printing used in one embodiment of the present invention, and the structure of the printing area 3 is the display film (display layer) 4 and the printing area 3 from the surface side. The black ink layer 2 and the support 5 are disposed. That is, the laminate 1 for laser printing is formed of a plastic film and at least part of which is a non-venting part, a support film 5 that is bonded to the display film 4 and at least part of which is a non-venting part, and a display. A black ink layer 2 containing carbon black provided adjacent to each of the non-venting part of the display film 4 and the non-venting part of the supporting member 5 between the non-venting part of the film 4 and the non-venting part of the support 5; .

  In the laminate 1 for laser printing of the present example, the entire surface of the bonding surface of the display film 4 to the support 5 and the bonding surface of the support 5 to the display film 4 is non-breathable and non-breathable (non-breathable). Breathable surface). Further, the black ink layer 2 in the printing area 3 is bonded to the adjacent members such as the display film 4 and the support 5 in the entire surface of the display film 4 and the support 5. Therefore, the black ink layer 2 is surrounded by the non-venting part of the display film 4 and the non-venting part of the support 5 and is disposed in a sealed space where the ventilation with the outside is blocked.

A braille pattern is formed on the display film 4 without irradiating at least the black ink layer 2 of the laminate 1 for laser printing shown in FIG. 1 with laser light (for example, YVO ₄ laser light) and perforating the display film 4 with the laser light. A hollow dome-shaped molded part (see reference numeral “6” in FIG. 7A, etc.) that constitutes the raised part is formed, and a Braille notation can be manufactured.
According to the laser braille printing method according to the embodiment of the present invention, when the support 5 is a relatively soft film such as a plastic film, both surfaces of the laser printing laminate 1 may be raised.
Further, when there is no laser light shielding layer covering the printing region 3 of the laser printing laminate 1, the raised portions can be formed by irradiating laser light from either the front or back surface of the laser printing laminate 1. it can. Therefore, a plurality of dome-shaped molded parts are provided in the display film 4 by irradiating a plurality of spots of the black ink layer 2 in a spot shape through the display film 4, and the plurality of dome-shaped molded parts A braille pattern can be constructed. Further, a plurality of dome-shaped molded portions are provided in the display film 4 by irradiating a plurality of locations of the black ink layer 2 through the support 5 in a spot shape, and braille is formed by the plurality of dome-shaped molded portions. Patterns can also be configured. In each situation where the laser braille printing method according to an embodiment of the present invention is implemented, the film on the surface side of the black ink layer 2 in the printing region 3 is the display film with the surface forming the braille display portion in the positive direction as the surface. 4 and the film on the back side of the black ink layer 2 in the printing area 3 becomes the support 5.
For example, a book obtained by extruding and laminating a molten polyethylene resin film 15 μm on a surface of a 20 μm thick biaxially oriented polypropylene film on which a laser printing region 3 is printed with a black ink layer 2 of a printing region 3 made of carbon black. Assume a case where laser braille printing is performed on the laser-printed laminate 1 used in one embodiment of the invention. In this case, when laser braille printing is carried out with the laminate alone, a dome-shaped molded portion is formed on the polyethylene film surface even if laser light is irradiated from any surface of the laser-printed laminate 1. A polyethylene film may be used as the display film 4. On the other hand, when laser braille printing is performed on the heat-sealed part where the polyethylene surfaces of the laminate are overlapped and heat-sealed, the film appearing on the surface is only a biaxially-stretched polypropylene film. A dome-shaped molded part is formed on the film. Therefore, in such a case, the biaxially stretched polypropylene film becomes the display film 4, and the biaxially stretched polypropylene film on the opposite side of the biaxially stretched polypropylene film forming the dome-shaped molded portion in the braille notation in the forward direction is the support 5. It may become.
In addition, in the case of the laser-printed laminate 1 formed of a film having a low softening point but hard at room temperature and a film having a higher softening point but softer than the film at room temperature, if laser braille printing is performed at room temperature, If the soft film becomes the display film 4 and the laminated body 1 is heated and laser braille printing is performed, a film having a lower softening point may be the display film 4. Thus, the distinction between the surface film 4 and the support 5 may not be determined unless the laser braille printing is actually performed.
Further, for example, the display film 4 covering the printing area 3 of the black ink layer 2 irradiated with the laser beam is heated, and the printing area 3 of the black ink layer 2 is irradiated with the laser beam to form a dome-shaped molded portion. Also good. In this case, the heating of the display film 4 and the irradiation of the laser beam may be performed simultaneously, or the laser beam may be irradiated in a state where the temperature of the display film 4 is increased after the heating of the display film 4.
Further, in the case of the laser-printed laminate 1 provided with braille notation portions on both sides, a film sandwiched between the display films 4 on both surfaces serves as the support 5.
As a special example of the laminate 1 for laser printing in which braille notation portions are provided on both sides, only the black ink layer 2 in the printing region 3 is provided without providing the support 5 between the display films 4, and the black ink layer 2 may be shared by the display film 4 on both sides. In this case, as a special case, one laminated body is divided into “regions having a Braille notation”, the surface film in which the Braille notation in the forward direction is made for each region is used as the display film 4, and the remaining film is the support 5. And

Further, when the support 5 is a plastic film, the method of bonding the display film 4 and the support 5 is such as dry lamination using an adhesive, extrusion lamination with a molten extrusion resin, thermal lamination, etc. Means generally used for bonding can be suitably used. In the case of extrusion lamination, an anchor agent is applied to the bonding surface as necessary.
In addition, the plastic film layer formed only by melt extrusion resin by extrusion lamination can be used suitably as the display film 4 of the laminated body 1 for laser printing used alone by one Embodiment of this invention.

Further, when at least a part of the support 5 is an object that cannot be processed by roll-to-roll, such as a plate-like product, a metal processed product, or a plastic molded product, the display film 4 and the film-like support 5 are bonded together. By sticking the display film 4 and the support 5 to the object, an embodiment of the present invention can be easily applied to a breathable object such as a wooden product or an object that requires the use of a special adhesive such as ceramics. It is convenient to apply to.
When the display film 4 and the object (support 5) that cannot be processed by roll-to-roll are directly bonded, the black ink layer in the printing area 3 can be obtained by bonding the display film 4 and the support 5 using an adhesive. This is advantageous because 2 can be firmly adhered to the display film 4 and the support 5.

  Note that, when an adhesive or a double-sided adhesive tape is used for bonding the display film 4 and the support 5 regardless of the shape or material of the support 5, the normal adhesive is a laser braille according to an embodiment of the present invention. Since the adhesive strength of the black ink layer 2 produced by the printing method is reduced by the combustion heat of the carbon, and the adhesive around the print pattern may be peeled off due to the increase in internal pressure when printing in braille, It is necessary to use an adhesive having heat resistance.

  Moreover, the laminate 1 for laser printing used in one embodiment of the present invention can be provided with a printing layer such as a character or a picture at any position and layer regardless of the printing method. However, when a printing layer is provided in the printing area 3, it is preferable to verify beforehand with a prototype or the like whether the laser printing is adversely affected by, for example, attenuating the laser beam. In addition, when the printing layer provided on the surface of the laser-printed laminate 1 used in the embodiment of the present invention is also provided in the printing region 3, the resin component of the ink burns and emits smoke by laser light irradiation, Since the display film 4 may be easily perforated, it may be verified with a prototype or the like in this case as well.

(Laser printing adhesive)
FIG. 2 shows an adhesive 1 ′ for laser printing used in an embodiment of the present invention. If the laminate 1 for laser printing used in an embodiment of the present invention is a film, it is the same as an ordinary adhesive film. In addition, a pressure-sensitive adhesive layer (adhesive layer) 7 is formed by applying a pressure-sensitive adhesive to the support 5 surface of the laser-printed laminate 1 used in one embodiment of the present invention. Bonded onto the release sheet 8. That is, in the laser printing pressure-sensitive adhesive 1 ′ shown in FIG. 2, the pressure-sensitive adhesive layer 7 is provided on the opposite side of the support 5 from the display film 4.
In addition, when the roll-to-roll process cannot be performed, for example, the support 5 of the laser-printing laminate 1 used in an embodiment of the present invention is plate-like, or the laser-printing laminate used in an embodiment of the present invention. Even when 1 is a film, when only a small amount is subjected to adhesive processing, the adhesive 1 ′ for laser printing can be produced even if a double-sided adhesive film is bonded to the surface of the support 5.
The adhesive body with braille notation according to one embodiment of the present invention in which braille printing is performed on the laser-printing adhesive body 1 ′ used in one embodiment of the present invention is a fixed form such as “shampoo”, “senzai”, “leopard”, etc. By creating and using a sentence with a Braille pattern, there is an advantage that it can be used even by a person who does not have a Braille printing device. Moreover, since the adhesive body with braille notation according to an embodiment of the present invention is molded in a state where the bulge portion is filled with gas, the dome-shaped molded portion ( (Braille pattern) has the advantage that it is difficult to dent.

(Laser printing heat sealable laminate)
FIG. 3 shows a laminate 1 for laser printing used in an embodiment of the present invention, in which a heat-sealable layer 9 having heat melting property is further provided on the surface of a base support 5 ′ to be bonded to the display film 4. The heat-sealable laminate for laser printing used in one embodiment of the present invention as the support 5 is shown. That is, in the laminate 1 for laser printing shown in FIG. 3, the heat-sealable layer 9 is provided on the opposite side to the display film 4 in the support 5 (particularly, the basic support 5 ′ in this example). Although not particularly illustrated, the support 5 can also be composed of a single heat-sealable layer 9. The laser-printed laminate 1 has a heat-sealing property, so that a package can be formed by forming a bag, using it as a lid for a molded container, or using it as an in-mold label.
FIG. 4A is a schematic plan view showing an example of the package 11 with braille notation when the braille display portion 12 is provided on the heat seal portion 13 of the bag body and the body portion other than the heat seal portion 13. b) is a schematic plan view showing an example of the package 11 with braille notation when the braille display portion 12 is provided in the unsealed portion 13 ′ outside the heat seal portion 13 of the bag body. The package (bag body) 11 shown in FIGS. 4 (a) and 4 (b) is provided with a heat seal portion 13, and the accommodating portion 15 defined by the heat seal portion 13 is the package body 11. It is provided inside. The braille display portion 12 provided on the package (bag body) 11 has the same configuration as the above-described laminate 1 for laser printing. In other words, the Braille display unit 12 has a structure in which the display film 4, the black ink layer 2, and the support 5 are laminated to form a plurality of dome-shaped molded parts that form a Braille pattern.
The Braille display unit 12 can be provided at the heat seal unit 13 or at other locations. Further, such a package is formed even before the “package after the contents M are accommodated in the accommodating portion 15” is formed from the “bag before the contents M are accommodated in the accommodating portion 15”. Even after this, laser braille printing according to an embodiment of the present invention can be applied to the braille notation 12.
Moreover, since the film of the fuselage part overlaps two sheets (that is, the laminate 1 on the front side of the fuselage part and the laminate 1 on the back side of the fuselage part overlap), the heat seal part 13 is supported from the fuselage part. The body 5 is thick and the support 5 is unlikely to rise even when laser braille printing is performed. Therefore, in the package (bag body) 11 formed using the thin / soft laminate for laser printing 1 in particular, the heat seal portion 13 is a suitable printing region 3. Therefore, when the package (bag body) 11 has the heat seal part 13, it is preferable to provide the display film 4 in the heat seal part 13 with a plurality of dome-shaped molded parts constituting a Braille pattern.
Further, when the heat seal portion 13 is provided on each of the front side and the back side of the outer side of the package (bag body) 11, the plurality of dome-shaped molded portions are each of the front side heat seal portion 13 and the back side heat seal portion 13. The display film 4 may be provided. In this case, on each of the front side and the back side of the package (bag body) 11, a desired Braille pattern configured by a plurality of dome-shaped molded portions can be provided.
Furthermore, when the laminated body which forms a package (bag body) has a barrier property like the case where the display film 4 has a barrier layer, the case where the metal vapor deposition film of a metal vapor deposition film is used as a barrier layer, etc. In the case of a packaging body in which the barrier property may be impaired or damaged when laser braille printing is applied to the body portion, laser braille printing is performed on the heat seal portion 13 or the unsealed portion 13 'outside the heat seal portion 13. It is good to carry out.
The laser braille printing on the heat seal part 13 is usually performed after the heat seal process of the heat seal part 13, although not particularly illustrated, an unsealed area 13 ′ is formed as a print area 3 inside the heat seal part 13. If provided, it may be carried out before heat sealing.
In addition, for example, when heat seal processing is performed to provide several line seals with a width of 1 to 2 mm at the upper and lower seals of pillow packaging bags such as snacks that require hermetic sealing, heat that provides laser braille printing If the unevenness of the seal part 13 is large, the dome-shaped molded part formed by Braille printing may be obstructed by the unevenness of the heat seal part 13 and cannot be identified. In such a case, it is possible to devise the shape of the sealing surface of the heat seal portion 13 such as making only the heat seal portion 13 where laser braille printing is desired to be a flat seal portion, or making only that portion an unsealed portion, etc. If so, it is preferable that the flat sealing process is performed again after the heat sealing process of the heat sealing unit 13.

(Double-sided braille printing)
FIG. 5 shows an example of a cross section of a laminated body (braille notation) in which dome-shaped molded portions are provided on both the front side and the back side. In the laminate shown in FIG. 5, the first display film (display layer) 4a, the first black ink layer 2a, the support 5, the second black ink layer 2b, and the second display film (display layer) 4b are provided. They are sequentially stacked.
Both the first display film 4a and the second display film 4b are formed of a plastic film, and at least a part thereof is a non-venting part. The 1st display film 4a is provided in the surface side of a laminated body (braille notation body), and the 2nd display film 4b is provided in the back surface side of a laminated body. Each of the first display film 4a and the second display film 4b is provided with a hollow dome-shaped molded portion 6.
The support 5 shown in FIG. 5 includes a first base support 5a ′ provided on the front side, a second base support 5b ′ provided on the back side, and the first base support 5a ′ and the second base support 5a ′. It has a laser light shielding layer 14 provided between the base support 5b ′. At least a part of the support 5 is a non-venting part, and in the example shown in FIG. 5, the first base support 5a ′ and the second base support 5b ′ form a non-venting part.
Both the first black ink layer 2a and the second black ink layer 2b contain carbon black. The first black ink layer 2a is formed between the non-venting part of the first display film 4a and the non-venting part of the support 5 between the non-venting part of the first display film 4a and the non-venting part of the support 5. The second black ink layer 2b is provided between the non-venting part of the second display film 4b and the non-venting part of the support 5 and the non-venting part and the support of the second display film 4b. 5 is provided adjacent to each of the non-venting portions.
As shown in FIG. 5, when the laser beam shielding layer 14 is present on the support 5, the black ink layers (the first black ink layer 2 a and the second black ink that constitute the print region 3 on both sides of the support 5. If the layer 2b) and the display film (the first display film 4a and the second display film 4b) are provided, the black ink layer is irradiated with laser light from the display film side on both sides of the laminate, thereby stacking the layers. Braille display portions 12 can be provided on both sides of the body. Although not shown in particular, even if the black ink layer 2 in the printing region 3 is provided on both sides of the laser light shielding layer 14 partially provided on the support 5, the braille display portions 12 can be provided on both sides of the laminate.

  Examples of the material that can be used as the laser light shielding layer 14 in the laser-printed laminate 1 used in an embodiment of the present invention include metallic foil, metallic gloss ink added with metallic powder, and the like. When laser braille printing is performed, it is dangerous if laser light passes through the laser-printing laminate 1, the contents M are damaged, laser light is printed on both sides of the laser-printing laminate 1, etc. It is preferable to provide the shielding layer 14. When the laser light shielding layer 14 is provided on the entire surface of the laminate 1 for laser printing, a metal foil can be preferably used, and when the laser light shielding layer 14 is partially provided, the metal gloss ink can be suitably used. . In addition, since a metal vapor deposition film lose | disappears when a metal vapor deposition film is irradiated with a laser beam, it cannot be used as the laser beam shielding layer 14.

FIG. 6 shows another example of a cross section of a laminate (braille notation) in which dome-shaped molded portions are provided on both the front side and the back side. In the laminate shown in FIG. 6 as well, the first display film (display layer) 4a, the first black ink layer 2a, the support 5, the second black ink layer 2b and the first display film (display layer) 4a as in the laminate shown in FIG. Two display films (display layers) 4b are sequentially laminated. However, in the example shown in FIG. 6, the laser light shielding layer 14 (see FIG. 5) does not exist, and the first black ink layer 2a and the second black ink layer 2b do not overlap each other in the projection in the stacking direction. Are arranged at positions shifted from each other in the direction perpendicular to the stacking direction.
Even without the laser light shielding layer 14 as described above, as shown in FIG. 6, the display film (the first display film 4 a and the second display film 4 b) and the black ink layer (the first black film in the printing area 3). If the ink layer 2a and the second black ink layer 2b) are present on both sides of the laminate 1, and the black ink layers in the laser printing areas 3 on both sides are shifted in position, the laser braille is placed on both sides of the laminate 1. Can be printed. In this case, by irradiating a laser beam from one side of the laminate 1 to perform forward-direction Braille printing on the display film 4 on one side and performing reverse Braille printing on the display film 4 on the other side. Both sides of the braille can be printed.

(Black ink layer 2 in print area 3)
The black ink layer 2 in the laser printing region 3 of the laser printing laminate 1 used in the embodiment of the present invention can be provided by printing black ink containing carbon black. Since the commonly used black ink pigment is composed of only carbon black, the black ink layer 2 in the printing region 3 in the laminate 1 for laser printing used in one embodiment of the present invention is usually carbon. Black ink layer 2 made of black, black such as black ink layer 2 in which black ink made of carbon is mixed with ink of other colors, or black ink layer 2 of light black color in which black ink is diluted with a resin component The laser printing method according to an embodiment of the present invention can also be applied to the system ink layer. Further, the laser printing method according to the embodiment of the present invention can be applied even when the black ink layer 2 is formed by applying black ink at a printing halftone dot instead of solid printing of black ink. However, if the carbon black content of the black ink layer 2 in the printing area 3 is small, it is necessary to reduce the scanning speed of the laser beam, so that the printing time becomes longer or in some cases perforation occurs. If the black ink layer 2 in the printing area 3 is not completely black, it is preferable to actually perform laser braille printing for verification.

  In the example shown in FIG. 1, the black ink layer 2 is provided on the support 5 side. However, the black ink layer 2 may be provided on the display film 4 side, or both sides of the display film 4 and the support 5. May be provided. Whether the black ink layer 2 of the printing area 3 is provided on the display film 4 side, the support body 5 side, or both sides is determined depending on the manufacturing process of the laser-printing laminate 1 used in the embodiment of the present invention. Taking this into consideration, it can be determined when designing the laminate.

As the resin component used in the ink, known materials such as sesame oil, drill oil, soybean oil, hydrocarbon oil, rosin, rosin ester, rosin modified resin, shellac, alkyd resin, phenolic resin, maleic resin , Natural resins, hydrocarbon resins, polyvinyl chloride resins, polyacetic acid resins, polystyrene resins, polyvinyl butyral resins, acrylic or methacrylic resins, polyamide resins, polyester resins, polyurethane resins, epoxy resins, urea One or more of resins, melamine resins, aminoalkyd resins, nitrocellulose, ethylcellulose, chlorinated rubber, cyclized rubber, etc. can be used in combination.
In addition, one or two kinds of auxiliary agents such as a plasticizer, a stabilizer, an antioxidant, a light stabilizer, an ultraviolet absorber, a curing agent, a crosslinking agent, a lubricant, an antistatic agent, a filler, etc. The above may be arbitrarily added to the ink.

  Examples of the plastic film for printing the black ink layer 2 in the printing area 3 include polyester resins such as polyethylene terephthalate used for ordinary packaging materials, polyamide resins such as various nylons, polyethylene resins, and polypropylene resins. Printing out of unstretched film, uniaxially stretched film and biaxially stretched film, film with barrier coating on these films, film coated with metal foil, metal deposited film, metal oxide deposited film, cellophane film, etc. A non-breathable film having mechanical suitability that can be passed through a machine can be selected and used as necessary.

  The printing method is particularly limited as long as it is a printing method capable of performing solid printing of the print region 3 on the non-breathable film, such as gravure printing, flexographic printing, letterpress printing, planographic printing, inkjet printing, silk printing, and the like. Although not necessary, gravure printing, flexographic printing, letterpress printing, and ink jet printing, which have many facilities capable of processing a plastic film in a wound state, can be suitably used in terms of easy post-processing.

  Ordinary printing is possible even when the printed material (display film 4, support 5, etc.) of the black ink layer 2 in the printing area 3 is an object that cannot be processed by roll-to-roll, such as a plate-like product, a metal processed product, or a plastic molded product. Since the black ink composed of the carbon pigment used in the above is used, it is not necessary to limit the printing method. For example, if the substrate is a plate, the size and shape of the substrate may be lithographic printing, silk printing, inkjet printing, etc., and if the substrate is a three-dimensional object, flexographic printing, inkjet printing, transfer printing, etc. Depending on the printing method, the printing method can be appropriately selected and used.

In addition, the black ink layer 2 in the laser printing region 3 of the laser printing laminate 1 used in the embodiment of the present invention needs to be sandwiched between non-venting portions (non-breathing film). By being sandwiched, the gas generated by burning carbon black or the like of the black ink layer 2 by laser light irradiation increases the pressure between the layers, and a hollow dome-shaped molded portion can be formed. When air-permeable films such as paper, non-woven fabric, microporous film, perforated film are in contact with the black ink layer 2 in the laser printing region 3, the gas generated between the layers is dispersed, and the pressure between the layers is reduced. It cannot be raised and a ridge cannot be formed.
In addition, the ink layer which does not contain carbon black except the ink which added the metal powder provided in contact with the black ink layer 2 of the laser printing area | region 3 of the laminated body 1 for laser printing used by one Embodiment of this invention, adhesion | attachment Coating layers such as an agent layer, an anchor coat layer, a primer layer, etc., when laser braille printing according to one embodiment of the present invention is carried out, are transmitted with laser light or resin together with the black ink layer 2 in the printing area 3 Since the ink can be burned, it has almost no effect on laser braille printing except for an ink layer containing an extremely high concentration of pigment. In the laminate 1 for laser printing used in one embodiment of the present invention, printing is not performed. It can be considered as being integral with the black ink layer 2 in the region 3. In general, it is also practiced to mix three primary colors to express a black color close to gray. However, such a black color transmits at least YVO ₄ laser light, but other than black ink containing carbon black. In some cases, the ink cannot be distinguished from the ink added with the pigment. Further, since white ink has large pigment particles, it is determined whether or not it functions as the laminate 1 for laser printing used in one embodiment of the present invention only by appearance, such as attenuating laser light when the coating amount is large. Therefore, in the case of the laser-printed laminate 1 having a configuration with no track record, it is preferable to produce a prototype in advance and verify it.

(Display film 4)
As the display film 4 of the laminate 1 for laser printing used in one embodiment of the present invention, a plastic film that is softened by heating can be used.
Specifically, the display film 4 may be anything as long as it is a plastic film used for a general packaging material. Particularly, a polyester-based resin such as polyethylene terephthalate, which is widely distributed and used as a general-purpose film. Polyamide resins such as various nylons, polyethylene resins, polypropylene resins, and other ethylene-vinyl acetate copolymers, cyclic polyolefin resins, ionomer resins, ethylene-propylene copolymers, ethylene-vinyl alcohol copolymers , Methylpentene polymer, polybutene polymer, acid-modified polyolefin resin, polyvinyl acetate resin, poly (meth) acrylic resin, polyvinyl chloride resin, polylactic acid resin, unstretched film, uniaxially stretched film or biaxially stretched film Or these fills Can be a film with a barrier coating, a film was deposited metal or metal oxide, co-extruded film with the resin, preferably used extrusion laminating films of the resin. In addition, a film in which a plurality of the films are laminated can be used as the display film 4.
When the resin is formed into a film, for example, film processability, heat resistance, weather resistance, mechanical suitability, dimensional stability, antioxidant properties, slipperiness, mold release properties, flame retardancy, antifungal properties, Various plastic compounding agents, additives and the like can be added for the purpose of improving and modifying the electrical characteristics, strength, etc. As general additives, for example, in addition to a lubricant, a crosslinking agent, an antioxidant, an ultraviolet absorber, a light stabilizer, a filler, an antistatic agent, a lubricant, an antiblocking agent, etc., a modifying resin is also used. can do.
In particular, a mat-like film is suitable as the display film 4 among the biaxially stretched films. The matte film has good slipperiness, so the fingertips are slippery and the braille is easy to identify. Matte film includes external haze such as film with irregularities on the surface by adding fine particles such as microsilica, film with sandblasting or hairline processing, film with fine irregularities on the surface during film formation, etc. Can be mentioned.
In addition, most of the sealant films used for food packaging materials have good slipperiness to prevent inner surface adhesion of bag-made products. Can also be suitably used as the display film 4.
Even if the film has poor surface slipperiness, the slipperiness can be improved by applying a mat-like ink to which a matting agent such as microsilica is added to the surface of the print area.
Moreover, since the braille notation 10 according to an embodiment of the present invention has water resistance and oil resistance, the braille can be identified by moistening the fingertip with water, oil, cream or the like.
In the case of an aluminum vapor-deposited film, at least in the case of YVO ₄ laser light, the metal vapor-deposited film disappears when irradiated with laser light, so there is no influence on laser braille printing. In addition, a film to which a colorant such as a dye other than black or a pigment is added can also be used as the display film 4, but after confirming in advance whether such a film does not attenuate laser light, the display film is used. 4 may be used.

  If the display film 4 is too thick, the height of the dome-shaped molded part is lowered, and if it is too thin, the display film 4 is easily perforated by the combustion heat of carbon black or the like burned by laser light irradiation. In addition, the melting point and softening point differ depending on the film material and whether it is a laminated body, the ease of punching and moldability also differ, and the processing conditions such as the presence or absence of heating during laser light irradiation also affect moldability and punchability. Therefore, the thickness of the display film 4 cannot be generally limited, and it is necessary to actually manufacture the desired laser-printed laminate 1 and confirm the formation state of the dome-shaped molded portion. Therefore, although the thickness of the display film 4 cannot be limited, if the thickness of the display film 4 is forcibly described, in the case of a single film, the biaxially stretched film has a thickness of 9 μm to 40 μm, and the unstretched film Those having a thickness of 10 μm to 50 μm are highly likely to be used as the display film 4.

(Support 5)
The support 5 of the laminate 1 for laser printing used in an embodiment of the present invention is a film other than a plastic film such as a cellophane film, a metal foil, etc. Can also be used alone or in layers. Further, if the support 5 is not used on the surface of the print area 3 that contacts the black ink layer 2, it is not necessary to consider the formation of the dome-shaped molded part, so that paper, nonwoven fabric, microporous film, perforated film, etc. Air-permeable films can be used.
The support 5 need not take into account the formation of the dome-shaped molded portion, but when the laser braille printing method according to one embodiment of the present invention is performed, the laser printing laminate used in one embodiment of the present invention. A dome-shaped molded part may be formed on the support 5 of the body 1. There is a case where it does not matter even if a dome-shaped molded portion is formed on the support 5, and there is a case where it does not, but if it becomes a problem, the support 5 is designed to be as hard / thick as possible, or the display film 4 It is advisable to take measures such as using a film having a lower softening point, a softer and thinner film, or heating the display film 4 to soften it when performing laser braille printing.

  Further, as the support 5 of the laminate 1 for laser printing used in one embodiment of the present invention, in addition to a sheet-like film that cannot be roll-to-roll processed, a smooth surface and Braille that can be bonded to the display film 4 A three-dimensional article having a notation space, such as a plastic molded article, a metal processed article, and a glass processed article, can also be used. The display film 4 may be bonded directly to these sheets and three-dimensional articles, or a laminate in which a film is bonded to the display film 4 as a part of the support 5 may be bonded.

  Note that if the thickness of the support 5 is too thin, it will be easily perforated by the heat of combustion of the carbon black, or the support 5 will likely rise, and the display film 4 will not easily rise due to the influence. is necessary.

(Dome shaped part)
7A shows a schematic cross-sectional view of the dome-shaped molded portion 6 provided in the laser-printed laminate 1 shown in FIG. 1, and FIG. 7B shows the internal configuration of each dome-shaped molded portion 6. It is a top view.
Each dome-shaped molded part 6 formed by the Braille printing method according to one embodiment of the present invention has a sealed hollow structure as shown in a schematic cross-sectional view in FIG. The display film 4 softened by the combustion heat is locally expanded and formed by the pressure of combustion gas such as burned carbon black. The carbon black in the portion where the dome-shaped molded portion 6 is formed is often burned out along the output pattern of the laser beam and often burned out in the form of dots or lines. In addition, it is assumed that the resin component of the ink and the adhesive, ink, film, etc. in contact with the black ink layer 2 are partially burned by the combustion heat of carbon black.
In the example shown in FIG. 7A and FIG. 7B, a plurality of laser spot portions 16 are provided by irradiating a plurality of portions of the black ink layer 2 with laser light in order to form one dome-shaped molded portion 6. It is done. The laser spot portion 16 is typically formed as a through hole in the black ink layer 2, but does not necessarily have to penetrate. Further, the number, size, shape and arrangement of the laser spot portions 16 for making one dome-shaped molded portion 6 can be obtained as long as the gas pressure required for making the desired dome-shaped molded portion 6 can be obtained. It is not limited.

  Generally, the height of the dome-shaped molded portion 6 may be 0.4 mm, but can be identified even with 0.3 mm. Even when a sufficient height cannot be obtained, it is possible to adjust the processing conditions, design the laminated body such as making the surface of the display film 4 have good sliding properties, devise manufacturing conditions, and apply water or oil to the fingertips. In some cases, the dome-shaped molded part 6 can be identified by the device of Braille users such as

  The conventional Braille notation 10 is “a raised portion formed into an open dome shape by an embossing method, a Braille device, etc.” shown in FIG. 8 (a), and a schematic sectional view in FIG. 8 (b). , A raised portion formed into a dome shape without an internal space by, for example, injection molding or foaming by partially heating a foamed film, and “a schematic sectional view shown in FIG. The braille pattern is expressed by “a raised portion where the ink is thickly deposited on the material or the foamed ink is heated and foamed”. The raised portion (dome-shaped molded portion 6) of the braille notation 10 according to one embodiment of the present invention has a hollow dome shape (see FIG. 7A), and FIGS. 8A to 8C. This is completely different from the structure of the raised portion of the conventional braille notation 10 shown in FIG. In particular, the raised portion (dome-shaped molded portion 6) of the braille notation 10 according to one embodiment of the present invention is made of a molded plastic film, and is not easily deformed even when compressed. The display film 4 is integrated with the display film 4 so that it does not easily fall off, and since it is made of a plastic film, it has a structure in which liquids and gases are difficult to enter.

(Laser Braille printing)
What is important for forming the dome-shaped molded portion 6 by the Braille printing method according to the embodiment of the present invention is to prevent the display film 4 and the support 5 from being perforated. When the display film 4 or the support 5 is perforated, gas generated by combustion of carbon black or the like of the black ink layer 2 leaks out of the laminate, and the interlayer pressure does not increase, so that the display film 4 can be raised in a dome shape. It can not be formed, or only a low raised portion (dome-shaped molded portion 6) that is difficult to obtain a touch feeling can be formed.

In general, laser light used for laser processing is roughly classified into two types according to wavelength. In particular, laser light having a wavelength of around 1064 nm cannot process a transparent object. Typical examples of laser light of this wavelength include YVO ₄ laser light, YAG (yttrium, aluminum, garnet) laser light, and FAYb laser light. The YVO ₄ laser beam can be printed on a metal surface and is suitable for performing fine marking. YAG laser light can be used for metal engraving and has a low wavelength. The FAYb laser beam can be printed with a small heat effect by shortening the pulse width depending on the model.

In addition, laser light having a wavelength of around 10600 nm can be processed into a transparent object and burns a plastic film, and thus is not used in the laser printing method according to an embodiment of the present invention. A typical example of this type of laser light is CO ₂ laser light.

As a laser beam for performing laser braille printing on the laser printing laminate 1 used in an embodiment of the present invention, a YVO ₄ laser beam having a wavelength of 1064 nm can be suitably used. This YVO ₄ laser beam can burn carbon black in the black ink layer 2 in the printing region 3 without perforating the display film 4 and / or the support 5, and can perform fine printing and high-speed printing. Excellent. In particular, the single mode beam has excellent laser output stability and can be printed without unevenness, so it can pass through almost transparent plastic films and ink layers that do not contain black pigment by fine output adjustment. The carbon black of the black ink layer 2 in the print region 3 existing between the two can be burned.

Even if YVO ₄ laser light is irradiated with strong energy, the combustion heat of carbon black, the carbon black burns, the resin of the black ink layer 2 in the printing region 3 and the resin of the adhesive layer are burnt and generated. The display film 4 and / or the support 5 may be melted and perforated by the combustion heat of carbon, or the metal foil of the laser light shielding layer 14 may be perforated. Moreover, even if the ink layer does not contain black pigment (carbon black), if the pigment concentration is extremely high, YVO ₄ laser light may not be transmitted. When doing this, it is necessary to verify in advance the conditions for printing without punching.

Three laser light outputs, scanning speed, and frequency are particularly important as laser light irradiation conditions to be verified in order to form the dome-shaped molded portion 6 in the laser-printed laminate 1 used in the embodiment of the present invention. .
The output is literally the output of the laser beam, usually expressed as a percentage of the maximum output of the laser marker used, and relatively representing the energy amount of the laser beam. If the output of the laser beam is too high, not only the display film 4 and / or the support 5 of the laminate 1 for laser printing used in one embodiment of the present invention is burned out, even if it is a YVO ₄ laser. Depending on these conditions, the aluminum foil used as the laser light shielding layer 14 is also cut. On the other hand, if the output of the laser beam is too low, the amount of combustion of carbon black in the black ink layer 2 in the printing area 3 is reduced, and the dome-shaped molded part 6 cannot be formed due to insufficient combustion gas and combustion temperature.
The scanning speed literally represents the scanning speed of the irradiation laser light, and usually indicates the scanning distance of the laser light per second. If the scanning speed of the irradiation laser beam is too high, the energy of the irradiation laser beam applied to the print area will be reduced and carbon black cannot be burned. The time laser beam is irradiated, and the display film 4 and / or the support 5 are perforated.
Even if the laser beam output is high, if the laser beam scanning speed is increased, the damage to the printed part is reduced. Conversely, if the laser beam output is low, the laser beam scanning speed is low, and the printed part damage is increased. .
The frequency represents the number of times the laser beam is output as a pulse output, and is usually expressed in kHz, and is an auxiliary condition for the output and the scanning speed. If the frequency is low, the number of pulses of the laser light decreases, but the amount of energy per pulse increases accordingly. Conversely, if the frequency is high, the energy amount of one pulse decreases.

  The above three conditions are intricately intertwined to construct a printing condition. If the output is high, the start point of the character and the intersection of the scanning lines are easy to perforate, or if the scanning speed is increased, the appearance of the printing may be deteriorated. There are also factors due to the performance of the substrate and the laser marker.

  Since the type, thickness, softening point, etc. of the plastic film constituting the laminate 1 for laser printing used in an embodiment of the present invention are determined by the design according to the use of the laminate, there are various types of laminates. There are countless numbers. In addition, the performance and characteristics of laser markers vary depending on the light source and manufacturer. Therefore, in order to form the dome-shaped molded portion 6 by the Braille printing method according to an embodiment of the present invention, it is necessary to obtain printing conditions for each laser printing laminate 1 in accordance with individual examples.

  In the Braille printing method according to one embodiment of the present invention, if the laser-printed laminate 1 can be heated, the display film 4 is heated, whereby the dome-shaped raised portion is easily formed, and the state By carrying out braille printing, a higher dome-shaped part can be formed as compared with the case where braille printing is carried out without heating.

  As a heating method of the laser-printed laminate 1 (particularly the display film 4), it is usually performed by blowing hot air, heating with an infrared heater, applying a hot plate, or using heat immediately after heat sealing. The film heating method can be used to heat locally or over a wide range. However, since the laser output device is often installed in a situation where the surroundings are covered to prevent danger, it is necessary to consider that the laser output device is not damaged by heat.

  Note that since there is no conventional laser braille printing technique according to an embodiment of the present invention, when laser braille printing is actually performed, for example, a braille pattern captured as an image on a laser marker operation computer is laser printed as a pattern. In addition, it is necessary to perform laser printing of a braille pattern formed by a small circle or polygon drawn in black on a monitor of an operation computer. One Braille pattern corresponds to one character, so if you create computer software that converts characters entered on the keyboard into Braille patterns and displays them on the monitor, you can greatly reduce the input work for laser Braille printing. it can. Moreover, it is preferable that expression patterns peculiar to Braille, such as capital letters and numerals, be linked to function keys in a broad sense such as keyboard shift keys and control keys. In addition, the presence / absence of a subscript can be selected, and if a subscript is selected, a braille pattern with a subscript can be confirmed on the monitor screen to help prevent an input error.

(Laser printing)
If the laser braille printing method according to an embodiment of the present invention is used, characters can be represented by the contrast between the burned-out portion of the black ink by laser light irradiation and the surrounding black ink layer 2. Can be printed. FIG. 9 is a schematic plan view showing an example of the braille notation 10 according to the embodiment of the present invention, which is formed by the Braille printing method according to the embodiment of the present invention and is appended with characters of braille notation content.
In the print area 3 of the braille notation body 10 shown in FIG. 9, a braille display portion 12 printed with braille by irradiation with laser light and a character display portion 17 printed with characters by irradiation with laser light are formed. For example, the character display unit 17 can be provided in the print region 3 by irradiating a laser beam to a portion of the black ink layer 2 that is not covered by the dome-shaped molding unit 5.
The character display unit 17 is provided in the vicinity of the dome-shaped molding unit 5 and indicates the meaning of the braille pattern configured by the dome-shaped molding unit 5. That is, the position of the braille pattern on the braille display unit 12 and the position of the character on the character display unit 17 correspond to each other. In the example shown in FIG. 9, for example, the position of the character display unit 17 corresponding to the position of the Braille pattern that means the character “B” in the Braille display unit 12 (in the example shown in FIG. 9, the Braille pattern that means “B”). A character “B” is formed at a position immediately below the position.
Conventionally, for example, in a pharmaceutical packaging box, the display content for Braille has been largely omitted from the display content for sighted people, so there was a frustration that sighted people who cannot identify Braille cannot share information with Braille users. However, as shown in FIG. 9, by allowing the sighted person to recognize the display content in Braille, an assistant who is a sighted person has an opportunity to learn Braille, especially for elderly middle-aged braille users who are increasing in recent years. Can help the sighted person to identify Braille, and the sighted person understands the Braille user. Thus, the braille notation body 10 having the print region 3 where the braille display portion 12 and the character display portion 17 are written can contribute to the improvement of the quality of life of the braille user. In addition, it is easy to write both Braille and letters, so you can send mail with letters indicating your address and address along with Braille, and Braille users and sighted people can check the correctness of the written contents. A new development of the braille notation 10 can be opened, such as being able to do both simultaneously and mutually.

  When a character is laser-printed using the Braille printing method according to an embodiment of the present invention, the black ink layer 2 in the printing region 3 of the laser-printed laminate 1 used in the embodiment of the present invention can be used. .

  It is also possible to print characters such as “Kana, Alphabet, Numbers” that are conventionally used by sighted people on personal computer monitors and have corresponding braille characters, and if necessary, Kanji characters can also be printed. it can.

Moreover, when a character is printed using the laser braille printing method which concerns on one Embodiment of this invention, the convex part of the display film 4 may be formed continuously on the character surface. In the case where the convex portion accompanying the character printing interferes with the braille identification, the convex portion accompanying the character printing should not be formed by printing the character under the condition that the character is printed on the display film 4 or the support 5. Can do. That is, the laser beam for character printing is irradiated to the location which is not covered with the dome-shaped shaping | molding part 6 among the black ink layers 2 through the display film 4, and the display film 4 or the support body 5 is irradiated with the laser beam. The character display unit 17 can be provided while punching. In this case, in the display film 4 or the support 5 that covers the printing area 3, a non-perforated portion 18 is provided by a dome-shaped molding portion 6 at a location that covers the Braille display portion 12, and a location corresponding to the character display portion 17. Is provided with a perforation 19. Moreover, the height of the convex part accompanying character printing can also be suppressed by making the character printing conditions into the minimum printing conditions which can burn carbon black, or making the character printing line width as thin as possible. In addition, if the display film 4 or the like may be burned out, characters and designs may be separately printed using CO ₂ laser light or the like.

(Application field of laser braille printing)
The laser braille printing method according to an embodiment of the present invention can be applied to a laminate having a simple configuration in which printing is performed on a base film and a heat-sealable film is laminated on the printing surface. Black ink made of carbon black is the most versatile black ink, and since most of the packages currently distributed have characters and barcodes printed using black ink, it is currently distributed except for single film packaging. The laser braille printing method according to an embodiment of the present invention can be applied only by providing the black ink layer 2 of the printing region 3 on most of the packaging bodies. Further, the laser braille printing method according to an embodiment of the present invention can be applied to a commercially available product including a package having a black print region by backside printing capable of Braille notation, and such a commercially available product. Can also be applied to the purchased product by applying the laser braille printing method according to one embodiment of the present invention. For example, the expiration date or the contents of the contents M can be shown in Braille on a food packaging bag such as a retort curry or snack, and the expiration date or efficacy target can be shown in Braille on a packaging bag such as a medicine or cosmetic. Moreover, the Braille notation to that effect can be given also to the package which requires the description for danger preventions, such as a fire warning and the unusable human body. In addition, when braille is written on the package, it is better not to be cut off at the time of opening in consideration of the written position.
In addition, a laminate formed by providing a heat sealable layer 9 after the black ink layer 2 in the printing area 3 is printed on the display film 4 as an in-mold label, or laser printing used in one embodiment of the present invention. A paper box, a liquid paper container, a cardboard box, or the like can be formed by pasting paper on the support 5 surface of the laminate 1 for use.
In addition, after performing Braille printing on the laser-printing adhesive 1 ′ used in one embodiment of the present invention, the laser-printing adhesive 1 ′ is pasted or used in one embodiment of the present invention. By sticking 1 'and then printing in braille, the package, milk carton, paper boxes including cardboard boxes, molded products, metal containers such as metal cans and spray containers, push buttons such as copiers and vending machines, Braille notation can be used for most objects, such as elevator push buttons and stairs handrails.
The laser-printing pressure-sensitive adhesive body 1 ′ used in one embodiment of the present invention can freely select the support 5, so that various pressure-sensitive adhesives can be used according to the application, and the thickness can be reduced to several tens of μm. Therefore, it is possible to provide a pressure-sensitive adhesive body with braille notation that is difficult to peel off according to the usage environment such as the object to be pasted and wetness.
In addition, the Braille notation 10 according to an embodiment of the present invention can be used for Braille publications, instruction manuals, restaurant menus, and the like without providing a heat-sealable layer or forming an adhesive. In particular, the Braille notation 10 obtained by outputting the Braille pattern to the laser printing laminate 1 immediately after being input to the computer can be used immediately. The manufacturing method of the braille notation 10 according to an embodiment of the present invention can be used.
The Braille standard has different dimensions for each country, but if it is computer software, it is easy to change settings such as the drawing position and size of graphics. Therefore, the laser marker operation computer can easily set the output of the Braille pattern in accordance with the country-specific Braille standard, and it is also possible to output the Braille pattern outside the standard that arbitrarily set the standard. It is also possible to easily obtain a braille notation 10 for practice of identifying Braille by setting a standard for Braille larger than usual.

[Examples related to the first embodiment]
Next, examples related to the first embodiment will be described in detail.

(Laser printing test method)
In this example, a laser printing test was performed using a YVO ₄ laser marker (manufactured by Keyence Corporation, trade name “MD-V9900”).

The input of the braille pattern to the laser marker is a 6-point braille formed by a solid circle with a diameter of 1.6 mm, with an output pattern of 2.1 mm between horizontal dots, 2.3 mm between vertical dots, and 5.2 mm between squares. This was done by inputting a braille pattern image.
Braille printing conditions were such that the scanning speed of the laser beam was fixed at 6000 mm / second, the frequency was fixed at 100 kHz, the output was 50% as a reference, and was changed in increments of 10% as necessary.
When braille printing was performed while heating, the braille printing surface was heated with hot air for 30 seconds and then irradiated with laser light. In addition, the hot air temperature in the immediate vicinity of a heating surface was about 90 degreeC.

Example 1
A double-sided pressure-sensitive adhesive tape with a release sheet 8 having the same dimensions is attached to the polyethylene terephthalate surface of the laminate 1A for laser printing used in one embodiment of the present invention, cut to 50 mm × 200 mm, and one embodiment of the present invention. An adhesive film for laser printing used in 1 was obtained.
On the polyethylene film surface of the adhesive film for laser printing, a pattern of 8 characters of “capital letters” and “braille” at room temperature, and a height of 3 mm corresponding to individual brailles with the position of 5 mm below the braille as a reference line After printing an alphabetic character “Braille” with a width of 2.5 mm, a character spacing of 5.2 mm, and a printing width of 0.04 mm at an output of 50%, the print portion is arranged at the center and cut into a length of 20 mm × width of 50 mm. The adhesive film with braille notation which concerns on one Embodiment of this invention was obtained.
The braille was formed without being perforated, had a sufficient height, and even a sighted person with no experience of reading braille could recognize the arrangement of the dots (dome-shaped molded portion 6) with his eyes closed.
Moreover, since the printed alphabetic character can be visually confirmed, even the sighted person who does not have Braille interpretation experience can recognize the content of the printed Braille. Since the character printing was perforated, the raised portion (dome-shaped molded portion 6) was not formed, and reading of Braille was not hindered.
Even if the release sheet 8 is peeled off and pasted on a beverage paper container, a medicine paper box, a home phone, a refrigerator door handle, or a magazine cover, a sighted person with no experience of Braille reading remains closed. The arrangement of the dots (dome-shaped molded part 6) could be recognized.

(Example 2)
The laminate 1B for laser printing used in an embodiment of the present invention is cut into a length of 297 mm × width 210 mm to form an A4 plate. This pattern was printed in braille for 6 lines with an output of 50% and a line spacing of 12 mm.
The braille is not perforated, and is formed without reverse printing on the back side of the braille printing surface, has a sufficient height, and even with a sighted person who has no experience of reading braille, The arrangement of the dome-shaped molded part 6) could be recognized.
Next, in the center of the back surface of the Braille printing surface, a pattern of 20 characters of “abcdefghijklmnopqrst” per line at room temperature and a height corresponding to each Braille with a position of 5 mm below the Braille as a reference line. A double-faced braille notation according to an embodiment of the present invention, in which 6 lines are printed with an alphabetic lowercase letter having a length of 3 mm, a width of 2.5 mm, a character spacing of 5.2 mm, and a printing width of 0.04 mm at an output of 50% and a line spacing of 15 mm. 10 was obtained.
The braille is formed without perforation and without reverse printing on the back surface, and has a sufficient height, so that even a sighted person with no experience of Braille interpretation can keep the eyes closed (dome-shaped molded part). The arrangement of 6) could be recognized.
In addition, since the surface on which the alphabet corresponding to each braille is printed can visually confirm the letters of the printed alphabet, even a sighted person who does not have Braille interpretation can recognize the content of the printed braille. Since the character printing was perforated, the raised portion (dome-shaped molded portion 6) was not formed, and reading of Braille was not hindered.

(Example 3)
The laminated body for laser printing 1C used in an embodiment of the present invention cut out to 150 mm × 200 mm, at room temperature, “numerical code shown in (a) of FIG. 10 (code“ S1 shown in FIG. 10 (a) ”. ”)” And “123456 (see symbol“ S2 ”shown in FIG. 10A)”. As a result of Braille printing at 50% output, Braille printing is performed from either the polypropylene side or the polyethylene side. However, a raised portion (dome-shaped molded portion 6) having a height sufficient for reading with a fingertip was formed on the polyethylene surface. Even when the polypropylene surface was touched with a fingertip, a point (dome-shaped molded portion 6) could not be recognized, and irregularities were generated to the extent that it was not known whether it was raised or depressed.
Next, the laminated body for laser printing 1C used in one embodiment of the present invention cut to 150 mm × 200 mm is folded in two so that the polyethylene surfaces face each other, and 10 mm wide on the three peripheral edge portions excluding the opening. After heat-sealing and manufacturing the bag body used in one embodiment of the present invention having a width of 100 mm and a length of 150 mm, while heating the laser light irradiation surface to the heat seal portion 13 facing the opening, ”And“ 123456 ”braille patterns printed at 50% output, resulting in a raised portion (dome-shaped molded portion 6) on the polypropylene surface irradiated with the laser beam, which has sufficient height, and is braille. Even a sighted person with no interpretation experience could recognize the arrangement of the dots (dome-shaped molded portion 6) with his eyes closed.

Example 4
The laser-printed laminate 1D used in one embodiment of the present invention is cut into 160 mm × 200 mm in a checkered vertical 8 square and horizontal 4 square, the unstretched polypropylene surfaces face each other and folded in half, and an opening is formed. A heat seal having a width of 10 mm was applied to the three peripheral edge portions except for a bag body used in an embodiment of the present invention of 100 mm × 160 mm. The bottom seal part facing the opening of the bag body is 100 mm long, and when viewed from either side, 50 mm from the end is black and the remaining 50 mm is white, and the back of the black part is white, white The back surface of the part has a black appearance.
On the one surface of the bottom seal portion, a black portion has a 7-character braille pattern of “numerical code” and “123456”, and a white portion is reversed from right to left “654321” shown in FIG. (Refer to reference sign “S2” shown in FIG. 10B.) And “numeric sign (refer to reference sign“ S1 ”shown in FIG. 10B)”. Braille printing was performed by irradiating a laser beam from the black surface side. As a result, a raised portion (dome-shaped molded portion 6) of seven braille characters “numeral sign” and “123456” is generated in the black portions on both sides of the bottom seal portion, and the braille has a sufficient height, and the braille is read. Even a sighted person with no experience could recognize the arrangement of the dots (dome-shaped molded portion 6) with his eyes closed.

(Example 5)
The laser-printed laminate 1E used in an embodiment of the present invention is cut into 160 mm × 200 mm in a checkered pattern of 8 squares and 4 squares, folded in two with the polypropylene faces facing each other, and the periphery excluding the opening A heat seal having a width of 10 mm was applied to the three sides of the end portion to produce a bag body used in an embodiment of the present invention of 100 mm × 160 mm. The bottom seal portion facing the opening of the bag body has a length of 100 mm, and 50 mm from the end is black and the remaining 50 mm has a white appearance.
When the braille print was performed by irradiating a laser beam from the black surface side with 50% output of a braille 7-character pattern of “numeric code” and “123456” at room temperature on the black portion of the heat seal portion 13 of the bag body, Since the perforation occurred and only about half of the whole raised portion was obtained, the same Braille printing was performed at an output of 40%. As a result, the Braille printing could be performed without the perforation. However, although the height of Braille (dome-shaped molded part 6) can be recognized with a fingertip, a sighted person who does not have Braille interpretation experience cannot confirm the placement of the dots (dome-shaped molded part 6) without visual confirmation. there were.
Next, while heating the black portion of the heat seal portion 13 of the bag body, a braille 7 character pattern of “numerical code” and “123456” is irradiated with laser light from the black surface side at an output of 50% and is printed in braille. As a result, braille (dome-shaped molded portion 6) is formed without perforation, and is higher than Braille when printed at 50% output at room temperature, even for sighted people who have no experience reading Braille. With the eyes closed, the arrangement of the dots (dome-shaped molded portion 6) could be recognized. Similarly, when the braille is printed at 60% output while heating, there is no perforation, and it is much higher than the braille that was heated and printed at 50% output. An easy Braille notation 10 was obtained.

(Example 6)
Assuming that the laser-printed laminate 1F used in one embodiment of the present invention is a bottom material, the laser-printed laminate 1D used in one embodiment of the present invention is a lid, the laminate 1F is 160 mm × 100 mm, and the laminate Cut 1D into a checkered pattern of 8 squares and 2 squares to 160 mm x 100 mm and laminate the laminated 1F co-extruded unstretched polypropylene film surface with the unstretched polypropylene film surface of laminated body 1D facing each other In addition, a virtual deep-drawn container packaging body in which a heat seal with a width of 10 mm was applied to the flange was formed by applying a heat seal with a width of 10 mm to the peripheral edge. The “virtual deep-drawn molded container package” refers to a molded container package in which a deep-drawn part is to be formed, and a molded container package before the deep-drawn part is actually formed.
In the lid heat seal part 13, the black part has a 7-character braille pattern of “numeric code” and “123456”, and the white part has a 7-character braille character of “654321” and “numeric code” that is reversed left and right As a result of irradiating a laser beam from the lid material side without heating at a power of 50% and printing the braille pattern in braille, the black part of the lid material and the bottom material have both “numeric code” and “123456” braille 7 A raised part of the character (dome-shaped forming part 6) is generated, and the braille has a sufficient height, and even a sighted person who has no experience of reading Braille recognizes the arrangement of the point (dome-shaped forming part 6) with his eyes closed. We were able to.
In addition, a 7-character braille pattern of “numerical code” and “123456” is applied to the portion of the heat seal portion 13 where the cover material is a white portion from the bottom material side without heating at an output of 50%. As a result of Braille printing by irradiating light, a raised portion (dome-shaped molded portion 6) of 7 characters of “Numeral code” and “123456” is formed on the bottom material, and the Braille has a sufficient height. Even a sighted person with no interpretation experience could recognize the arrangement of the dots (dome-shaped molded portion 6) with his eyes closed.

(Example 7)
17 types of commercially available laser printing experimental samples (samples a to k and m to r) are heated on the body film, or a sample having no black solid print area that can be printed in braille on the heat seal portion 13 is heated on the body film. However, a 7-character braille pattern of “numeric code” and “123456” was printed in braille by irradiating laser light from the surface side of the package with an output of 50%.
After performing laser braille printing, a sighted person who has no experience of reading braille touches the braille with his / her finger and makes a relative evaluation based on the following criteria.
A: The height of the point is sufficient, and when the finger is slid, a feeling of being caught on the fingertip is obtained, and the arrangement of the point can be easily recognized even when the eyes are closed.
○: The height of the points can be recognized sufficiently, but there are 1 to 2 Braille characters that cannot be recognized unless they are visually confirmed.
Δ: It can be recognized that the dots are lined up, but the Braille that cannot recognize the arrangement of the dots unless visually confirmed is half or more.
X: It is difficult to recognize because the height of the point is low, and the arrangement of the point is not known unless it is visually confirmed. Alternatively, the dome-shaped molded part is not formed by perforation.

(Example 8)
A black solid portion and an orange solid portion in the body portion of a commercially available experimental sample for laser printing g were cut out and overlapped with the unstretched polypropylene surfaces facing each other, and heat-sealed with a width of 10 mm. When the details of the configuration of the heat seal portion 13 are described with the thickness of the film omitted, OPP / black ink / white ink / ad / CPP / ad / white ink / orange ink / OPP are obtained.
A 7-character pattern of “654321” and “numerical code” braille characters reversed left and right while heating was printed on the heat seal portion 13 by irradiating laser light from the orange surface side at an output of 50%.
As a result, a raised portion (dome-shaped molded portion 6) of seven braille characters “numerical code” and “123456” is generated in the black portion, and the braille has a sufficient height and even a sighted person who has no experience of reading braille. With the eyes closed, the arrangement of the dots (dome-shaped molded portion 6) could be recognized.

[Second Embodiment]
Next, a tactile information notation in which a tactile information pattern expressing characters such as alphabets other than Braille, symbols, figures and the like is formed will be described.

  In the following description, “characters” (also referred to as “touch characters”) are understood to include not only characters such as alphabets but also symbols and figures for convenience of description. In addition, in the following description, the term “figure” or “figure” can broadly refer to elements (symbols, figure shapes, etc.) other than characters. “Tactile characters” and “tactile figures” refer to characters and figures composed of a set of a plurality of raised parts, respectively. Characters and figures that can directly transmit information are referred to as “raised parts themselves” or “raised parts”. “Tactile characters” and “tactile drawings” are constituted by “smooth portions provided adjacent to the portions”.

  In the present embodiment, detailed description of the same configurations, operations, and effects as those in the first embodiment is omitted. For example, the description about the Braille in the above description according to the first embodiment is understood as a “tactile information display unit”, the “braille information notation” is understood as “tactile information notation”, etc. It can be properly understood as an explanation regarding ("touch characters").

(Laminate for laser printing)
For the laser print laminate of this embodiment, reference is made to the laser print laminate 1 according to the first embodiment shown in FIG.

  For example, in each situation in which the laser printing method according to an embodiment of the present invention is implemented, the film on the surface side of the black ink layer in the printing region is the display layer with the surface on which the tactile information notation portion in the positive direction is formed as the surface. The film on the back side of the black ink layer in the printing area serves as a support.

  When laser printing is performed on the heat-sealed part where the polyethylene surfaces of the laminate are overlapped and heat-sealed, the film appearing on the surface is only a biaxially stretched polypropylene film. When a ridge is formed, the biaxially stretched polypropylene film becomes the display layer, and the biaxially stretched polypropylene film on the opposite side of the biaxially stretched polypropylene film that forms the dome-shaped bulge with the tactile information notation in the forward direction becomes the support There is. In addition, the distinction between the surface film and the support may not be determined unless laser printing is actually performed.

In the case of a laminate for laser printing having tactile information notation portions on both sides, a film sandwiched between display layers on both surfaces serves as a support.
Further, as a special example of a laminate for laser printing in which tactile information notation portions are provided on both sides, only a black ink layer in a printing area is provided without providing a support between display layers, and the black ink layer is used as a display layer on both sides. May be shared. In this case, the tactile information notation section is divided for each information, and the surface film on which the tactile information notation in the forward direction is made for each information area is used as the display layer, and the remaining film is used as the support. In addition, when only one square drawing is printed, even if both sides are simultaneously printed with one laser printing, the same tactile information is printed on both sides, even when viewed from the front and back sides. Let the film of the back surface of a display layer be the support body of the said display layer.

(Laser printing adhesive)
For the laser print adhesive of this embodiment, reference is made to the laser print adhesive 1 'according to the first embodiment shown in FIG.
The adhesive body with tactile information notation according to an embodiment of the present invention, which is printed on the laser-printing adhesive body used in the present embodiment, is a tactile information that represents a fixed sentence such as “shampoo”, “senzai”, and “leopard”. By producing and using a pressure-sensitive adhesive with a notation, there is an advantage that it can be used even by a person who does not have a laser marker. In addition, the adhesive body with tactile information notation according to an embodiment of the present invention is formed in a state where the bulge is filled with gas. It has the advantage of being difficult to dent.

(Laser printing heat sealable laminate)
For the laser-printing heat-sealable laminate of this embodiment, reference is made to the laser-printing laminate 1 according to the first embodiment shown in FIG.

  FIG. 11A shows a case where the heat seal part 13 and the body of the bag (package 111 with tactile information notation) are provided with a tactile information notation 110 (tactile information display part 112), and FIG. Schematic plan view showing an example of a package 111 with tactile information notation when a tactile information notation 110 (tactile information display 112) is provided in an unsealed portion outside the heat seal portion 13 of the package 11 with notation. It is. The tactile information display unit 112 can be provided at the heat seal unit 13 or at any other location, and before or after the package 111 is formed, the laser printing according to the embodiment of the present invention. Can be applied.

  In addition, since two films of the body part overlap each other in the heat seal part 13, the support body is thicker than the body part, and the support body is not easily raised even if laser printing is performed. It can be set as a suitable printing area in the package 111 formed of the laminate for use.

Further, when the laminated body forming the package 111 has a barrier property, and there is a barrier layer in the display layer, or when the metal vapor deposition film of the metal vapor deposition film is used as the barrier layer, the laser printing is performed on the body. In the case of a package in which the barrier property is impaired or may be impaired when applied to the part, laser printing may be performed on the heat-sealed portion or the unsealed portion outside the heat-sealed portion.
Laser printing on the heat-sealed part is usually performed after heat-sealing, but not particularly shown, but when an unsealed area is provided as a printing area in the heat-sealed part, laser printing may be performed before heat-sealing. Sometimes you can.

  In addition, for example, when several line seals are applied with a width of 1 to 2 mm in the upper and lower seal portions of a pillow wrapping bag such as snack snacks that require sealing properties, the unevenness of the heat seal portion that performs laser printing is If it is large, the dome-shaped raised portion formed by printing may be disturbed by the unevenness of the heat seal portion and may not be identified. In such a case, devise the seal surface shape of the heat seal bar, such as making only the seal part of the part to be laser-printed a flat seal, or making only that part an unsealed part, and if possible after line sealing It is recommended to perform a flat seal again.

(Double-sided printing)
For the double-sided printing of this embodiment, refer to FIG. 5 according to the first embodiment. That is, when the laser beam shielding layer 14 is present on the support 5, if a black ink layer (2 a, 2 b) and a display layer (display film 4) are provided on both sides of the support 5, By irradiating laser light from the display layer side, the tactile information display unit 112 can be provided on both surfaces of the laminate. Although not shown in particular, even if the black ink layers (2a, 2b) in the printing area are provided on both sides of the laser light shielding layer 14 partially provided on the support 5, the tactile information display portions 112 are provided on both sides of the laminate. be able to.

  Further, even if there is no laser light shielding layer in this embodiment, as shown in FIG. 6, the display layer and the black ink layer in the printing area are present on both sides, and the positions of the black ink layers in the laser printing area on both sides are determined. If they are shifted, laser printing can be performed on both sides. In this case, double-sided printing is performed by irradiating laser light from one side, printing on the display layer on one side in the forward direction, and printing on the display layer on the other side in reverse. can do.

(Black ink layer in printing area)
About the black ink layer of the printing area of this embodiment, it is the same as that of 1st Embodiment, The plastic film which prints the black ink layer of the printing area of this embodiment, the printing system, and the printing material of the black ink layer of a printing area This is the same as in the first embodiment.

In addition, the black ink layer in the laser printing region of the laminate for laser printing used in the present embodiment needs to be sandwiched between non-breathable films. The gas generated by burning carbon black or the like by laser light irradiation can increase the pressure between the layers and form a hollow dome-like raised portion, as in the first embodiment described above.
In addition, an ink layer, an adhesive layer, and an anchor coat layer that do not contain carbon black except for ink added with metal powder provided in contact with the black ink layer in the laser printing region of the laser printing laminate used in the present embodiment. And when the coating film such as the primer layer is subjected to the laser printing according to the present embodiment, the laser beam is transmitted or the resin component can be burned together with the black ink layer in the printing region. Except for an ink layer containing an extremely high concentration of pigment, laser printing is hardly affected, and the laser printing laminate used in this embodiment is considered to be integrated with the black ink layer in the printing region. In general, it is also practiced to mix three primary colors to express a black color close to gray. However, such a black color transmits at least YVO ₄ laser light, but other than black ink containing carbon black. In some cases, the ink cannot be distinguished from the ink added with the pigment. Furthermore, since white ink has large pigment particles, it may not be possible to determine whether or not it functions as a laminate for laser printing to be used in this embodiment, such as attenuating laser light when the coating amount is large. Therefore, in the case of a laminated body for laser printing having a configuration with no track record, it is preferable to create and verify a prototype in advance.

(Display layer)
Also, the display layer of the laminate for laser printing used in the present embodiment can be a plastic film that is softened by heating, as in the first embodiment.
In particular, a mat-like film is suitable as the display layer in the biaxially stretched film. Since the matte film has good slipperiness, the fingertips are slippery and the tactile information can be easily identified.
Moreover, since the tactile information notation according to the present embodiment has water resistance and oil resistance, the tactile information can be identified by moistening the fingertip with water, oil, cream, or the like.
Incidentally, the aluminum deposition film, at least YVO ₄ when using a laser beam, there is no effect on the laser printing since when irradiated with laser light metal evaporated film (aluminum deposited film) is lost, the appearance changes. A film to which a colorant such as a dye other than black or a pigment is added can also be used, but such a film is preferably used after confirming that laser light is not attenuated in advance.

  In addition, the thickness of the display layer cannot be limited, but if the thickness of the display layer is to be described, in the case of a single film, a biaxially stretched film of 9 μm to 40 μm and an unstretched film of 10 μm to 50 μm should be used. There is a high possibility that

(Support)
The support for the laser-printed laminate used in the present embodiment is the same as the support for the laser-printed laminate according to the first embodiment. The paper layer used as the base material was coated using a coater with an auxiliary agent added to the mixture of pigment and adhesive, if necessary, and then a transparent coat or surface treatment was applied as necessary. Coated paper can also be used as a support.
It should be noted that even if a dome-shaped ridge is formed on the support, there are cases where it does not matter or may become a problem. If this is the case, the support is designed to be as hard and / or thick as possible, or the display layer It is preferable to take measures such as using a film having a lower softening point, a softer and thinner film, or heating the display layer when performing laser printing.

  In addition, as a support for the laminate for laser printing used in the present embodiment, a plastic sheet having a cut sheet that cannot be rolled to roll, a smooth surface on which a display layer can be bonded, and a tactile information notation space. Articles, processed metal products, processed glass products, and three-dimensional articles can also be used.

(Dome-shaped protuberance)
For the dome-shaped raised portion formed by the printing method according to the present embodiment, refer to FIG. 7 according to the first embodiment.

  In the case of Braille, it is necessary to confirm the number and position of the points with the tactile sensation of the fingertip, and the height of the raised portion is required to be at least about 0.3 mm. The tactile character and the tactile figure formed by the protruding dotted line according to the embodiment of the present invention do not need to read the number and position of the points like Braille, and it is only necessary to follow the series of points with the tactile sense of the fingertip. Even if it is smaller than the braille point and is formed with a low raised portion, it can be easily read with the tactile sensation of the fingertip. Although it depends on the size of the dots and the reader's ability, even a tactile character or a tactile figure composed of dots having a height of about 0.05 mm can be read. When the protruding dotted lines according to the embodiment of the present invention are confirmed by the tactile sensation of the fingertip, the recognizable distance between the dotted lines is more easily recognized as the protruding dotted line is thinner. The ability to form tactile characters and tactile figures with small points means that tactile information can be displayed in a small space, but the laser printing method according to an embodiment of the present invention is smaller than other methods. The ability to print is excellent. Also, the smaller the point, the more convenient the laser printing laminate used in one embodiment of the present invention is less likely to be perforated. Furthermore, it is convenient to print in a smaller space, leading to a reduction in printing time.

  In addition, even when the height of the raised portion cannot be obtained, tactile information can be obtained by designing the laminated body and devising the manufacturing conditions such as adjusting the processing conditions and making the surface of the display layer have good slipperiness. In some cases, the pattern can be identified. In addition, since the top of the raised portion of the protruding dotted line according to the embodiment of the present invention has a gentle curve, even if the reader touches a large amount of information, the fingertip is hardly damaged. Further, since the display layer is a plastic film, it can be read with water or oil on the fingertip.

  A Braille notation produced by a conventional Braille forming method is, for example, a method of forming a raised portion into an open dome shape by an embossing method or a Braille device whose schematic sectional view is shown in FIG. A schematic cross-sectional view is shown in FIG. 8 (c), and a method of forming a raised portion in a dome shape without an internal space by partially heating and foaming a foamed film, etc. It is made on the basis of a method of forming a raised portion by thickening ink on a base material or heating and foaming a foamed ink that has been printed. On the other hand, the structure of the point (raised portion) of the tactile information notation according to the present embodiment is a hollow dome shape, which is completely different from the structure of the point (raised portion) of the conventional braille notation. For example, the point (protrusion part) of the tactile information notation according to this embodiment is covered with a molded plastic film, so that it is difficult to be deformed even when compressed, and the film that serves as a base material Since it is constructed integrally, it is difficult for the raised portion to fall off, and since it is covered with a plastic film, it has a structure in which liquid and gas are difficult to enter.

(Laser printing)
The laser printing method according to the present embodiment is the same as the laser printing method of the first embodiment described above.
As a laser beam for performing laser printing on the laminate for laser printing used in the present embodiment, YVO ₄ laser beam having a wavelength of 1064 nm can be suitably used.

  Since the types, thicknesses, softening points, etc. of the plastic film constituting the laminate for laser printing used in this embodiment are determined by the design according to the use of the laminate, there are innumerable types, and laser markers Since the performance and characteristics of the laser beam differ depending on the light source and manufacturer, in order to form the dome-shaped raised portion by the printing method according to the embodiment of the present invention, printing is performed for each laminate for laser printing in accordance with each embodiment. It is necessary to obtain conditions.

  In the printing method according to this embodiment, if it is possible to heat the laminate for laser printing, the display layer is easily formed by heating, and by performing printing in that state, heating is not performed. A higher dome-shaped bulge can be formed as compared with the case where printing is performed.

  As a method of heating the laminate for laser printing, using a normal film heating method such as blowing hot air, heating with an infrared heater, applying heat with a hot plate, utilizing heat immediately after heat sealing, etc. Can be heated locally or extensively. However, since the laser output device is often installed with its surroundings covered with a shielding plate to prevent danger, it is necessary to consider that the laser output device is not damaged by heat.

  In addition, since there is no tactile information notation technology by laser printing, when laser printing is actually performed, for example, a pattern formed with dotted lines is imaged using a graphic drawing software and input to a laser marker operating computer, It is necessary to take the step of laser printing the image. Even with such a method, it is significantly simplified compared to conventional Braille forming methods that require a plate making process. By creating computer software that outputs dotted lines, laser printing The input work can be greatly reduced. In addition, if a software for converting an image composed of lines into a dotted line and outputting it is created, the tactile drawing can be greatly simplified.

  The shape of the dots constituting the dotted line output by the laser printing method according to an embodiment of the present invention may be a round shape such as a circle, an ellipse, or a capsule shape, and may be a square, a rectangle, a diamond, a triangle, or a star. It may be a polygonal shape such as a mold. However, it is safe to use a rounded shape, a square, or a rectangle that is difficult to perforate even if a dotted line with a large point is output, as the shape of the point constituting the dotted line.

  Although it is not necessary to particularly limit the distance between the dotted lines that are output by the laser printing method according to the embodiment of the present invention, the length of the dots and the dotted lines that have the same distance between the dots are generally used. Use it. However, if the distance between the dots is too wide, it becomes difficult to recognize the tactile information, and a larger space is required for displaying characters and figures, which is useless. Also, if the distance between the characters is too narrow, the bottoms of the adjacent ridges stick together and perforation tends to occur, but even if the bottoms of the ridges stick together and the points are connected, tactile information can be obtained with the fingertips. It does not matter if it can be recognized. In any case, it is advisable to conduct an actual laser printing test before implementation.

  There is no point in limiting the thickness (width) of the dotted line output by the laser printing method according to an embodiment of the present invention. For example, “, (comma)” or “! (Exclamation mark)” is displayed thicker than the alphabet in a single sentence, the headline touch character is thicker and / or larger, Tactile information can be easily obtained by making it thicker and making other lines thinner. However, if the dotted line is too thin, the raised portion is also small, so that it is difficult to recognize the tactile information pattern, and if the dotted line is too thick, perforation tends to occur. Also, since the line may become thicker or thinner depending on the structure of the laminate for laser printing, a laser printing test is usually performed on the basis of a thickness of about 0.3 mm to 1 mm to make it easy to recognize with a fingertip. It is recommended to devise the size and arrangement of the tactile characters and the drawing method of the tactile drawings while checking.

(Tactile)
By using the laser printing method according to an embodiment of the present invention, any character in the world can be represented as tactile information. However, since the distance between the projected dotted lines that can clearly grasp the two projected dotted lines as two lines is at least 2 to 3 mm depending on the thickness of the dotted line, it is as small as the alphabet and katakana. Compared with the characters represented by the line, characters represented by a large number of lines such as kanji characters need to have a larger space per character.
In addition, the lower case letter “l” and the number “1”, the upper case letter “O” and the number “0” are very similar to each other. Have. The characters that are very similar but can be judged by the sighted person from the context in daily life can be judged from the context even by tactile characters, but they can be easily judged visually, such as the lowercase letters “e” and “s”. Since there are characters that are difficult to distinguish by tactile sense for each language, the size of the characters should be determined according to such characters. Furthermore, it is also effective to easily distinguish the shapes of characters that are difficult to distinguish by tactile sensation by partially extending the characters, changing the angle, or using a block body and a cursive body together.
FIG. 12 is a schematic plan view showing an example of a tactile information notation unit according to an embodiment of the present invention. By writing such tactile characters on the product, the contents can be written, and it can be made difficult for the visually impaired to misuse. In addition, because it is written in ordinary characters, it has increased in recent years as the number of diabetic patients has increased, and even elderly visually impaired people who cannot use Braille can read by tactile sense and cannot use Braille. Even people with disabilities can assist visually impaired people. In addition, it is possible to create mails by printing addresses and addresses, and to create new ways to use tactile information notation, such as no need to create separate information for visually impaired and sighted people be able to.

(Application field of laser printing)
The laser printing method according to an embodiment of the present invention can be applied to a laminate having a simple configuration in which printing is performed on a base film and a heat-sealable film is laminated on the printing surface. Black ink made of carbon black is the most versatile black ink, and since most of the packages currently distributed have characters and barcodes printed using black ink, it is currently distributed except for single film packaging. The laser printing method according to an embodiment of the present invention can be applied only by providing a black ink layer in the printing area on most of the packaged products. For example, a tactile information pattern can be written at the time of product manufacture as a tactile information with a shelf life or contents in a food packaging bag such as a retort curry or a snack, and a expiration date or effect target in a packaging bag of a medicine or cosmetic. In addition, tactile information to that effect can be similarly written on a package requiring a danger prevention display such as a fire caution or a human body unusable. In addition, when notifying tactile information on the package, it is preferable not to be cut off when opened in consideration of the notation position.

  In addition, the above-mentioned tactile information notation body (tactile information pattern), bag body and packaging body are used for an in-mold label formed by bonding a heat-sealable layer to a back-printed film, or a back-printed film and a metal plate are used. It can also be used for laminate cans formed by bonding, or paper can be bonded to the support surface of the laminate for laser printing used in one embodiment of the present invention to form paper boxes, liquid paper containers, cardboard boxes, etc. .

In addition, by pasting the printed matter on the laser-printing adhesive used in one embodiment of the present invention or by pasting the laser-printing adhesive used in one embodiment of the present invention, for example, the packaging Body, milk cartons, paper boxes including cardboard boxes, molded products, metal containers such as metal cans and spray containers, push buttons such as copiers and vending machines, and structures such as elevator push buttons and stairs handrails, etc. Tactile information can be written on most objects.
Since the adhesive for laser printing used in an embodiment of the present invention can freely select a support, various adhesives can be used according to the application, and the thickness can be reduced to several tens of μm. It is possible to provide an adhesive body with tactile information notation that is difficult to peel off according to the usage environment such as the object and water.

  Further, the above-mentioned tactile information notation (tactile information pattern) can be used for publications, instruction manuals, restaurant menus, etc. without providing a heat-sealable layer or forming an adhesive, and in particular, a computer. It can be used for press releases and mail creation by making use of a technique that has not been available in the past.

  In addition, since a tactile map can be created easily, it is possible to easily create a tactile map of a room map in an accommodation facility, an escape route map in an emergency, and a wide area map or a detailed map of an information map of a collective facility. It is also possible to easily display on both surfaces of a single laminate.

Next, a katakana pattern shown in FIG. 16 was printed at the center of the back surface of the printing surface at room temperature.
The tactile characters were formed without punching and without reverse printing on the back surface, and even a sighted person with no experience of reading tactile characters could recognize the tactile characters with their eyes closed. .
Moreover, since each tactile character can visually confirm the character, a sighted person can recognize normally.

(Example 11)
As a result of printing the letters “Beer” and “123456” shown in FIG. 12 at room temperature on the laminate 2C for laser printing used in one embodiment of the present invention cut out to 150 mm × 200 mm, the polypropylene surface, Even if printing was performed from any of the polyethylene surfaces, protrusions having a height sufficient for reading with a fingertip were formed on the polyethylene surface. Even if the polypropylene surface was touched with a fingertip, the point could not be recognized, and irregularities were generated to the extent that it was not known whether it was raised or depressed.
Next, the laminate 2C for laser printing used in an embodiment of the present invention cut into 150 mm × 200 mm is folded in two with the polyethylene surfaces facing each other, and 10 mm wide on the three peripheral edge portions excluding the opening. After heat sealing and manufacturing a bag body used in an embodiment of the present invention having a width of 100 mm and a length of 150 mm, the laser beam irradiation surface is heated on the heat seal portion facing the opening, as shown in FIG. As a result of printing the tactile characters “Beer” and “123456”, protrusions are formed on the polypropylene surface on the side irradiated with the laser beam, and even a sighted person who has no experience of tactile character recognition can recognize characters with closed eyes. did it.

(Example 12)
The laser-printed laminate 2D used in an embodiment of the present invention is cut into 160 mm × 200 mm in a checkered pattern of 8 squares and 4 squares, and the unstretched polypropylene surfaces face each other and folded in half.

The pattern was printed by irradiating a laser beam from the black surface side of the black portion without heating. As a result, a “Beer” tactile character was generated in the black portions on both sides of the bottom seal portion, and the tactile character could be recognized with closed eyes even by a sighted person who did not have a tactile character interpretation experience.

(Example 13)
The laser-printed laminate 2E used in one embodiment of the present invention is cut into 160 mm × 200 mm in a checkered pattern of 8 squares and 4 squares, folded in two with the polypropylene faces facing each other, and the periphery excluding the opening A heat seal having a width of 10 mm was applied to the three sides of the end portion to produce a bag body used in an embodiment of the present invention of 100 mm × 160 mm. The bottom seal portion facing the opening of the bag body has a length of 100 mm, and 50 mm from the end is black and the remaining 50 mm has a white appearance.
As a result of printing the letters “Beer” and “123456” shown in FIG. 12 at room temperature on the black portion of the heat seal portion of the bag body, a protrusion is generated on the polypropylene surface on the side irradiated with the laser beam, Even sighted people who had no experience of reading tactile characters could recognize characters with their eyes closed.
Next, the pattern “Beer” and “123456” shown in FIG. 12 was printed on the black portion of the heat seal portion of the bag body while heating. As a result, the pattern was higher than the touch characters printed at room temperature. As a result, a tactile information notation that was very easy to read was obtained.

(Example 14)
Assuming that the laser-printed laminate 2F used in one embodiment of the present invention is a bottom material, and the laser-printed laminate 2D used in one embodiment of the present invention is a lid, the laminate 2F is 160 mm × 100 mm, and the laminate 2D is cut into 160 mm x 100 mm in checkered vertical 8 squares and horizontal 2 squares, and the laminated 2F co-pressed unstretched polypropylene film surface and laminated 2D unstretched polypropylene film surface are stacked face to face In addition, a virtual deep-drawn container packaging body in which a heat seal with a width of 10 mm was applied to the flange was formed by applying a heat seal with a width of 10 mm to the peripheral edge.
In the lid heat seal portion, the black portion has the “Beer” pattern shown in FIG. 14A, and the white portion has the right and left reversed, the “Beer” pattern shown in FIG. 14B. The left-right reversal pattern was printed by irradiating laser light from the lid material side without heating. As a result, a “Beer” tactile character appears on both the black part of the lid and the bottom material, and the tactile character has a sufficient height so that even a sighted person with no experience of reading the tactile character can keep his eyes closed. I was able to recognize tactile characters.
In addition, the pattern of “Beer” and “123456” shown in FIG. 12 is printed on the heat seal portion where the cover material is white by irradiating laser light from the bottom material side while heating. did. As a result, tactile characters were generated on the bottom material, and the tactile characters could be recognized with eyes closed even by sighted people who had no experience in reading tactile characters.

(Example 15)
17 types of commercially available laser printing experimental samples (samples a to k and m to r shown in Table 5), or a sample without a black solid printable area that can be printed on the heat seal portion, While heating, the pattern “Beer” and “123456” shown in FIG. 12 was printed by irradiating the surface of the package with laser light.
After laser printing, a sighted person who had no experience of reading the tactile characters read the tactile characters with their fingers. As a result, all the samples could recognize the tactile characters.

(Example 16)
A black solid portion and an orange solid portion in the body portion of a commercially available experimental sample for laser printing g were cut out and overlapped with the unstretched polypropylene surfaces facing each other, and heat-sealed with a width of 10 mm. When the details of the structure of the heat seal portion are described with the film thickness omitted, OPP / black ink / white ink / ad / CPP / ad / white ink / orange ink / OPP are obtained.
On the orange surface of the heat seal portion, while printing, the left and right reversed pattern of “Beer” shown in FIG.
As a result, a tactile character was generated in the black portion on the opposite surface of the orange surface, and the tactile character could be recognized with the eyes closed even by a sighted person who had no experience of tactile character interpretation.

(Example 17)
A square dot having a side length of 0.5 mm is formed on the surface of a polyethylene terephthalate film having a thickness of 12 μm of the laser-printed laminate 2G used in an embodiment of the present invention cut out to 210 mm × 297 mm. 0.08 mm continuous dotted line, a dotted line with a side of 0.7 mm square with a dotted space of 0.4 mm, a side with a side length of 1.0 mm square with a dotted line of 0.7 mm, And the four types of dotted lines of a square point with a side length of 1.4 mm and a dotted line with a space of 1.0 mm between the dots, the alphabet, numbers and symbols shown in FIG. A tactile information notation according to an embodiment was obtained.
The tactile sensation information notation is formed without perforation. A square point with a side length of 0.5 mm is connected by a dotted line with a point space of 0.08 mm, and a square point with a side length of 0.7 mm is a point space. Tactile characters formed by a dotted line with a length of 0.4 mm and a dotted line with a square point with a side length of 1.0 mm with a space of 0.7 mm between dots, even for sighted people who have no experience in reading the tactile characters, keep their eyes closed. I was able to identify. A tactile character formed by a dotted line consisting of a square point with a side length of 1.4 mm and a space between points of 1.0 mm has a small character with respect to the size of the point and is difficult to identify. Even letters formed with large dots can be identified by touch.
Further, since the characters shown in FIG. 13 are arranged in alphabetical order, the characters can be identified even if the sense of touch is a little ambiguous. However, when a normal word is printed, there are characters that are difficult to identify by touch. In the case of Braille, the dots are arranged on the matrix, whereas the tactile characters are formed by dotted lines at various angles, so it is difficult to understand the upper and lower characters while touching the dotted lines for identification. It is one of the factors when it is difficult to identify.
Therefore, when it is difficult to understand the upper and lower sides of the character, as shown in FIG. 15, if an underline parallel to the character string is provided below the tactile character, the upper and lower sides of the tactile character can be clearly recognized. Even those who are unfamiliar with identification can now be easily identified.

(Example 18)
The katakana shown in FIG. 16 is 8 mm long on the polyethylene terephthalate film surface having a thickness of 12 μm of the laminate 2G for laser printing used in one embodiment of the present invention cut out to 210 mm × 297 mm in the same manner as the alphabet. × Tactile characters formed by printing while printing with a dotted line in which a square point with a side length of 0.7 mm and a size of a size that fits in a square of 8 mm wide, with a character interval of 10 mm, and a space of 0.4 mm between the dots, Even a sighted person who had no experience of reading tactile characters could identify characters with his eyes closed.
In addition, as shown in FIG. 17, when an underline parallel to the character string is provided under the tactile character with a protruding dotted line, the top and bottom of the tactile character can be clearly seen, and even a sighted person who has no experience in tactile character interpretation can see the Words could be easily recognized while closed.

(Example 19)
On the surface of a polyethylene terephthalate film having a thickness of 12 μm of the laminate 2G for laser printing used in one embodiment of the present invention, cut into 180 mm × 180 mm, the braille, touch characters, and plural types of dotted lines shown in FIG. A pattern consisting of the above was printed while heating, and a guide diagram with a tactile information notation according to an embodiment of the present invention, which was 105 mm wide × 115 mm long, was prepared. All the dotted lines and braille formed on the guide map were easily recognized.
In addition, as a result of creating a guide map by tactile drawing in the same procedure as the above content with only 80% of printing condition output, all the points formed become high in tactile sensation, and the dotted line formed on the guide map more easily, and I could recognize Braille.
As described above, by using the laser printing method according to the embodiment of the present invention, it is possible to easily provide a tactile information notation that is easily recognized by a visually handicapped person by combining various tactile information notations.

(Example 20)
A dotted line shown in FIG. 19 is arranged on the polyethylene terephthalate film surface having a thickness of 12 μm of the laminate 2G for laser printing used in an embodiment of the present invention, cut out to 180 mm × 180 mm, and then filled with dots. A drawing of 50 mm wide × 30 mm long was printed while heating. As a result, the rectangle formed by the protrusion and the cross portion without the central protrusion could be easily recognized by the tactile sense of the fingertip.
As described above, if the laser printing method according to an embodiment of the present invention is used, the surface can be represented by a diagram in which dotted lines are arranged side by side and filled with dots, so that a company logo, a picture, a pictogram, and the like are represented. It is possible to present unprecedented expressions not only for visually impaired people but also for sighted people.
