Abstract

To enable scratch printing at a low cost and in a small lot.SOLUTION: A lottery number 55, along with arbitrary patterns 561, 562, 563, etc., are printed using a toner on a base sheet such as a cardboard, like a printed matter 51 shown in (b1), by a first printing machine (printer) 41 shown in (a1). Next, a film layer 58 is pasted by a laminator pasting machine 42 shown in (a2), like a printed matter 52 shown in (b2). Then, in a second printing machine (printer) 43 shown in (a3), a shielding layer 59 is formed by the toner, like a printed matter 53 shown in (b3). The shielding layer 59 becomes peelable by melting and solidifying the toner at a temperature higher than a melting temperature and lower than a fixing temperature. Therefore, low-cost, small-lot scratch printing can be achieved without using a plate as in silk screen printing or off-set printing.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a scratch print and an apparatus and method for producing the same.

  Conventionally, by printing a shielding layer on unique information such as a lottery number or an authentication number, which can be individually identified, the information is kept secret, and the shielding layer is kept secret. Scratch printing that exposes by shaving is widely performed.

  FIG. 8 is a diagram illustrating a process of manufacturing a typical conventional scratch printed matter. The left (a) column in FIG. 8 schematically shows each of the printing presses 11 to 14, and the right (b) column is a front view of the scratch prints 21 to 24 that have left each of the printing presses 11 to 14. The example in FIG. 8B shows a scratch card on which a lottery number 25 or the like is printed as the scratch prints 21 to 24. FIG. 8B shows a state in which individual cards are cut off for easy understanding, and the number of stages of actually passing through each of the printing presses 11 to 14 is, for example, 20 cards are reduced to one. It is handled in the state of a printed sheet, and finally cut by a cutting device (not shown), and cut into cards as shown in FIG. 8B.

  In this prior art, first, as shown in FIG. 8 (b1), an arbitrary pattern 26 is printed on a base sheet (21) such as cardboard by the offset printing machine 11 of FIG. 8 (a1). In the example of FIG. 8 (b1), the picture 26 is printed with photographs 261, 262, and 263 of the product, an application period 264, a two-dimensional barcode 265 of the application destination address, and the like. Offset printing press 11 is a full color printing press that uses CMYK inks and corresponding screens.

  Next, in the electrophotographic printing machine (printer) 12 shown in FIG. 8A2, as shown in FIG. 8B2, the lottery number 25, which is variable information, is printed with a single color toner. Subsequently, in the silk screen printing machine 13 shown in FIG. 8A3, a varnish 28 is printed in a frame 27 surrounding the lottery number 25 as shown in FIG. 8B3. Thereafter, as shown in FIG. 8 (b4), a scratch ink 29 is printed in the frame 27 in the silk screen printing machine 14 of FIG. 8 (a4).

  As described above, in the conventional scratch printing, the unique information (25) that can be individually identified is printed by the printing machine (printer) 12 on the base sheet 21 that cannot be seen through, such as paper. After a varnish layer (28) serving as an anchor layer is formed by a silk screen printing machine or an offset printing machine 14, a scratch ink (shielding layer) is formed by a silk screen printing machine or an offset printing machine 14 using a special ink. 29 are formed.

  Therefore, Japanese Patent Application Laid-Open No. H11-163,873 discloses a method in which unique information that can be individually identified is formed on a base sheet by offset printing, and a release layer made of a transparent ink composition is formed by offset printing so as to protect the information. By forming a scratch concealing layer on the surface by electrophotographic on-demand printing, a scratch printed matter capable of shaving off the scratch concealing layer while obtaining an appropriate adhesive force of the scratch concealing layer and a method of manufacturing the same have been proposed. ing.

JP 2013-237200 A

  According to the above-mentioned prior art, the release layer is offset-printed with a transparent ink, and the concealment layer can be printed thereon with toner using an electrophotographic method, that is, using a copying machine or a printer. Therefore, the hiding layer can be printed on demand by a printer, and no plate is required.

  However, in the above-described conventional technology, the transparent release layer is still formed by the silk screen printing or the offset printing. When the transparent release layer is varnished, the coating film is thin, for example, about 1 μm. Therefore, the individual information that can be individually identified in the lower layer is performed by the silk screen printing or the offset printing (not performed by the toner). More specifically, the ink has a thickness of 1 μm or less in silk screen printing or offset printing, whereas the ink has a thickness of 20 μm, and a varnish cannot absorb the difference in thickness. Therefore, in the above-described conventional technology, the unique information that can be individually identified and the release layer made of the varnish need to be formed by the above-described plate-based silk screen printing or offset printing.

  Here, in the silk screen printing and the offset printing, a plate is required (in the case of a color, the number of colors is required), and a plate making process (plate making machine) is required in addition to the printing device, which increases initial costs and increases the printing device. Then, from the start of printing until the paper becomes stable, hundreds of waste papers are generated, which is wasteful. As described above, when the steps of the silk screen printing and the offset printing are included in the scratch printing, there is a problem that the cost increases in the case of a small lot.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a scratch printed matter, a scratch printing apparatus and a scratch printing method in which all steps of printing can be performed by an electrophotographic method.

  The scratch printed matter of the present invention includes a base sheet on which desired information and / or a picture is printed, a film layer formed on the base sheet, and a toner having a temperature higher than its melting temperature and lower than the fixing temperature. And a shielding layer formed on the film layer by melting and solidifying and shielding the desired information and / or picture.

  Further, the scratch printing apparatus of the present invention includes a first printing apparatus for printing desired information and / or a picture on a base sheet, and a film on the base sheet printed by the first printing apparatus. A laminating device for laminating a layer, and a shielding layer for shielding the desired information and / or picture on the film layer by melting and solidifying the toner at a temperature higher than its melting temperature and lower than the fixing temperature. And a second printing device.

  Still further, the scratch printing method of the present invention includes a first printing step of printing desired information and / or a picture on a base sheet, and a step of printing on the base sheet printed in the first printing step. An attaching step of attaching a film layer, and forming a shielding layer on the film layer by melting and solidifying the toner at a temperature higher than its melting temperature and lower than a fixing temperature, thereby shielding the desired information and / or picture. And forming a second printing step.

  According to the above-described configuration, desired information such as unique information that can be individually identified such as a lottery number or an authentication number, a desired pattern that decorates the lottery number or the authentication number, or a desired pattern for scratch art. On the base sheet on which the pattern of the pattern is printed, at least on the desired information and / or the portion of the pattern, at the time of realizing the scratch printing for forming a shielding layer for shielding them (to prevent them from being seen through), A film layer is interposed between the base sheet and the shielding layer as an anchor layer so that even if the shielding layer is scratched, information and / or pictures formed on the lower base sheet are not cut off.

  The varnish layer that has been widely used in the past is extremely thin, and when used in an electrophotographic printing apparatus, cannot absorb the thickness of the toner, for example, 20 μm. Therefore, instead of the varnish layer, a predetermined thickness as an anchor layer is used. For example, a film layer having a thickness of 80 to 100 μm is used. Thereby, the desired information and / or picture is formed on the base sheet by electrophotography, that is, toner printing, and further, the toner layer can be formed on the film layer by electrophotography. . On the other hand, if the toner is dissolved and solidified as usual, it cannot be scraped even if it is scratched. Therefore, with respect to the shielding layer, the temperature of the fixing roller for fixing the toner layer formed by electrophotography by applying heat and pressure to the printed matter is set to a temperature higher than the melting temperature of the toner and lower than the fixing temperature. Thus, although the toner is melted and solidified, the adhesiveness of the toner is reduced as compared with the case where the temperature is equal to or higher than the normal fixing temperature, and the toner can be peeled off by scratching.

  Therefore, as in the case of silk-screen printing or offset printing using a special ink for the shielding layer, without using a plate, and a printer that forms desired information and a pattern and the silk-screen printing and offset printing Both the desired information and the pattern on the base sheet and the shielding layer can be formed by an electrophotographic image forming apparatus such as a copying machine or a printer without using a plurality of printing methods. Thus, scratch printing can be realized at low cost and in a small lot.

  Further, in the scratch printed matter of the present invention, a resin layer which is easily peelable from the film layer is further formed on the film layer, and the shielding layer is formed on the resin layer.

  According to the above configuration, a resin layer that is easy to peel off from the film layer is further provided on the film layer serving as an anchor layer that prevents information and / or pictures formed on the base sheet from being scraped off by scratching. In addition, the peeling layer made of toner is more easily peeled.

  As a result, peeling (scratch) and remaining (unevenness) are reduced, which is particularly suitable for scratch art. The resin layer is made of silicon and may be formed by attaching a film or applying a resin.

  Preferably, the desired information and / or picture is unique information that can be individually identified, and the shielding layer is a solid screen formed of a single color toner.

  Preferably, the film layer is made of polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), or silicone resin. The heat-resistant temperature of the film layer is, for example, 100 to 140 ° C for polypropylene (PP), 60 to 85 ° C for polyethylene terephthalate (PET), and 60 to 80 ° C for polyvinyl chloride (PVC). .

  On the other hand, in the scratch printed matter of the present invention, the melting temperature is 80 ° C., and the fixing temperature is 160 ° C. Therefore, the temperature of the fixing roller of the toner forming the shielding layer is set to, for example, 200 ° C. in accordance with the heat resistance temperature, the melting temperature and the pressing force, and in consideration of the heat absorption by the base sheet. Possible shielding layers can be realized.

  Further, the scratch printed matter of the present invention comprises a transparent base film on which desired information and / or a picture is printed, and a toner wherein the toner is melted and solidified at a temperature higher than its melting temperature and lower than a fixing temperature. And a shielding layer formed on the surface opposite to the surface on which the desired information and / or picture is formed, and shielding the desired information and / or picture.

  Still further, the scratch printing apparatus of the present invention comprises a first printing apparatus for printing desired information and / or a picture on a transparent base film, and a toner which has a temperature higher than its melting temperature and lower than a fixing temperature. And forming a shielding layer for shielding the desired information and / or pattern on the surface of the base film opposite to the surface on which the desired information and / or pattern is formed. And a printing device.

  Further, the scratch printing method of the present invention includes a first printing step of printing desired information and / or a picture on a transparent base film, and a step of printing the toner at a temperature higher than its melting temperature and lower than the fixing temperature. A second layer, which is melted and solidified to form a shielding layer for shielding the desired information and / or pattern on a surface of the base film opposite to the surface on which the desired information and / or pattern is formed; And a printing step.

  According to the above configuration, the base film for printing desired information or pattern for scratch art or the like is transparent, and the desired information and / or pattern is printed on one surface, and the desired information and / or pattern is printed on the other surface. Form a shielding layer that blocks (can not be seen through) to achieve scratch printing.

  Although the shielding layer is a toner layer formed by electrophotography, if the toner is dissolved and solidified as usual, it cannot be scraped even if it is scratched. Therefore, the toner is melted by setting the temperature of the fixing roller for fixing the toner layer formed by electrophotography to a temperature higher than the melting temperature of the toner and lower than the fixing temperature by heating and pressing the printed material. In addition, although the toner is solidified, the adhesiveness of the toner is lowered as compared with the case where the temperature is equal to or higher than the normal fixing temperature, and the toner can be peeled off by scratching.

  Therefore, unlike the case of silk screen printing or offset printing using a special ink, the shielding layer does not use a plate, and the desired information and pattern are also opposite to those of the base film in the electrophotography at a normal fixing temperature. Since printing is performed on the surface, both the desired information and the pattern and the shielding layer can be formed by an electrophotographic image forming apparatus such as a copying machine or a printer. Thus, scratch printing can be realized at low cost and in a small lot. In addition, the shielding layer is not limited to the conventional solid scene, but can be formed in a different pattern using multiple colors of toner, providing a new scratch printed matter, especially scratch art that has never been seen before can do. The base film may be colored if desired information and / or a pattern printed on the back surface can be seen through.

  Further, in the scratch printed matter of the present invention, the desired information and / or picture is common information and / or picture, and the shielding layer is formed of another desired picture formed by a plurality of color toners. It is characterized by the following.

  According to the above configuration, what is shielded by the scratch printed matter is, in many cases, unique information that can be individually identified such as the lottery number or the authentication number, but the common information and the pattern are shielded. Even so, since the shielding layer is formed by toner, an unprecedented scratch printed matter can be realized by forming the shielding layer itself with another pattern.

  Preferably, the base film is made of at least one of a melamine resin, a polycarbonate resin, and an acrylic resin.

  As described above, the scratch printed matter and the scratch printing apparatus and method of the present invention form a film layer serving as a toner anchor layer on a base sheet on which desired information and / or a picture is printed, and further thereon, By melting and solidifying at a temperature higher than the melting temperature and lower than the fixing temperature, a peelable toner layer is formed and used as a shielding layer.

  Further, as described above, the scratch printed matter and the scratch printing apparatus and method of the present invention have a structure in which desired information and / or a picture is printed on one side of a transparent base film opposite to a melting point, In addition, by melting and solidifying at a temperature lower than the fixing temperature, a peelable toner layer is formed and used as a shielding layer.

  Therefore, unlike the case where the cover layer or the shielding layer is subjected to silk-screen printing or offset printing, a low-cost, small-lot In addition, scratch printing can be realized. Also, the shielding layer can be formed in a different pattern using a plurality of color toners.

(Embodiment 1)
FIG. 1 is a schematic sectional view of a scratch printed matter 3 according to one embodiment of the present invention, and FIG. 2 is an exploded perspective view of the scratch printed matter 3. The scratch printed matter 3 of the present embodiment is also a scratch card in which a lottery number or the like, which is desired secret information, is shielded similarly to the scratch printed matter 2 shown in FIG.

  The scratch printed material 3 of the present embodiment is attached to a base sheet 31 on which desired information and / or a picture is printed by a toner layer 32 (indicated by gradation in the example of FIG. 2), and is adhered on the base sheet 31. It comprises a film layer 33 and a shielding layer 34. The shielding layer 34 is exceptional in this embodiment, and the toner is melted and solidified at a temperature higher than its melting temperature and lower than the fixing temperature, is formed on the film layer 33, and has a desired shape. Obscure information and / or pictures (make them invisible). The film layer 33 is interposed so that the toner of the shielding layer 34 and the toner of the toner layer 32 do not adhere to each other.

  FIG. 3 is a diagram illustrating a manufacturing process of the scratch printed matter 3. In FIG. 3, similarly to FIG. 8, the left (a) column schematically shows an apparatus constituting a manufacturing process. The manufacturing process of the present embodiment includes a printing machine 41 and a laminator sticking machine. 42 and a printing machine 43. The right column (b) of FIG. 3 is a front view of the scratch prints 51 to 53 that have left the respective printing presses 41, the laminator sticking machine 42, and the printing press 43. The example of FIG. 3 also shows a scratch card on which a lottery number 55 or the like is printed as the scratch prints 51 to 53. FIG. 3B shows a state in which the card is separated into individual cards for simplicity, and the number of stages that actually pass through each printing machine 41, the laminator sticking machine 42, and the printing machine 43, for example, is plural. Twenty cards are handled as printed sheets, and finally cut by a cutting device (not shown) to be cut into cards as shown in FIG. 3B.

  First of all, in the present embodiment, the first printing apparatus is notable, and the electrophotographic printing machine (printer) 41 shown in FIG. 3 (a1) for realizing the first printing process is used in FIG. 3 (b1). As shown by the scratch printed matter 51, the lottery number 55, which is variable information, is printed together with an arbitrary picture 56 on the base sheet 31, such as a thick paper, whose back is not visible through the toner. In the example of FIG. 3 (b1), the pictures 561, 562, and 563 of the product, the application period 564, the two-dimensional barcode 565 of the application destination address, and the like are printed as the picture 56. The printing machine (printer) 41 is a full-color printing machine using CMYK toner. For example, photographs 561, 562, and 563 are full-color, and the application period 564, the two-dimensional barcode 565, and the lottery number 55 are printed with a single-color toner. However, it is possible to form all the images shown in FIG.

  In the printing press (printer) 41, a fixed picture 56 and a lottery number 55 of variable information are simultaneously image-formed, and these data are transferred from a personal computer or the like to the printing press (printer) 41 each time printing is performed. Alternatively, only the data of the picture 26 serving as the background may be transmitted in advance, and only the data of the lottery number 55 may be sequentially transmitted. Alternatively, the data of the picture 26 and a program for changing the lottery number 55 are transmitted from the personal computer to the printing machine (printer) 41, and the printing machine (printer) 41 sequentially creates the lottery number 55 which is variable information. Then, the data may be fitted to the data of the picture 26.

  Next, in the laminating machine 42 of FIG. 3A2, which is a laminating apparatus that realizes a laminating process, as shown in the scratch printed matter 52 of FIG. 3B2, the film layer 33 of FIGS. A corresponding film layer 58 is applied. In the example of FIG. 3, the film layer 58 is formed by attaching a film by the laminator attaching machine 42, but may be formed by applying a laminator resin by a coating machine. In particular, in the case of a small lot, coating formation is advantageous. In the case of the application formation, the film layer 58 may be formed only in the scratch frame 57 shown in FIG.

  Then, in the electrophotographic printing machine (printer) 43 of FIG. 3A3, which is a second printing apparatus and realizes the second printing process, as shown by a scratch print 53 of FIG. 3B3, A shielding layer 59 corresponding to the shielding layer 34 in FIGS. 1 and 2 is formed by toner.

  FIG. 4 is a diagram schematically illustrating a fixing process in an electrophotographic printing machine (copier or printer). The paper 72 on which the image of the toner 71 is transferred from a photosensitive belt or a photosensitive drum (not shown) on the upstream side is conveyed to a nip portion between a fixing roller 73 and a pressure roller 74. The rollers 73 and 74 are pressed against each other by a predetermined clamping force 75. A fixing belt 77 is wound around the fixing roller 73 and the heating roller 76. Therefore, on the sheet 71 conveyed in the direction of the arrow 78, the toner 71 is melted at the nip between the rollers 73 and 74, and a part of the toner 71 enters the fibers of the sheet 71 as shown in FIG. Then, by being solidified by heat radiation, as shown by reference numeral 71a, it is firmly adhered to the paper 72.

  On the other hand, it should be noted that in the present embodiment, the temperature of the fixing roller 73 is set to a temperature higher than the melting temperature of the toner 71 and lower than the fixing temperature, as shown in FIG. In addition, although the toner 71 is melted and solidified, the adhesiveness of the toner 71 is lowered as shown by reference numeral 71b, and the toner 71 can be peeled off as compared with the case of the normal fixing temperature in FIG. That is. Therefore, even if the film layer 33 is interposed between the base sheet 31 and the shielding layer 34 as an anchor layer, and the shielding layer 34 is scratched, the lottery number 55 (toner layer 55) formed on the lower base sheet 31 32) is not cut off.

  By the way, the varnish layer which has been widely used for scratch printing is extremely thin, and when used in an electrophotographic printing apparatus, it cannot absorb the thickness of the toner, for example, 20 μm. Therefore, in this embodiment, a film layer 33 having a predetermined thickness, for example, 80 to 100 μm is used as the anchor layer instead of the varnish layer. In this way, the lottery number 55 (toner layer 32), which is the desired information, is formed on the base sheet 31 by electrophotography, that is, by printing toner, and the toner layer by electrophotography is further formed on the film layer 33. Is formed.

  With this configuration, when realizing the scratch printing, as shown in the prior art of FIG. 8, when the shielding layer (scratch ink 29) is silk-screen printed or offset printed (14) using a special ink. As described above, a printer (12) for forming desired information and a pattern is used without using a plate, and a plurality of printing methods are used in combination with the printing machines (11, 13, 14) for the silk screen printing or the offset printing. Without performing, both the desired information (lottery number 55) on the base sheet 31 and the shielding layer 34 can be formed by an electrophotographic image forming apparatus (41, 43) such as a copier or a printer. it can. Thus, scratch printing can be realized at low cost and in a small lot. For example, a variable scratch print such as a face photograph can be obtained. As the printing presses (printers) 41 and 43, the same machine may be used at different times.

  Preferably, the film layer 33 is made of polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), or silicone resin. In this case, the heat resistance temperature of the film layer 33 is, for example, 100 to 140 ° C. for polypropylene (PP), 60 to 85 ° C. for polyethylene terephthalate (PET), and 60 to 80 ° C. for polyvinyl chloride (PVC). In order to easily separate the shielding layer 34 and protect the toner layer 32 reliably, the thickness of the film layer 33 is 20 μm or more for polypropylene (PP) and polyethylene terephthalate (PET) and 70 μm for polyvinyl chloride (PVC). That is all.

The temperature of the fixing roller 73 may be any temperature as long as the temperature of the toner 71 is higher than the melting temperature and lower than the fixing temperature, as described above. The temperature depends on whether the toner 71 is a pulverized toner or a polymerized toner, the color of the toner, that is, what the pigment is, the nipping pressure 75 of the nip portion, the material and thickness of the film layer 33, the speed of image formation, (Sheet passing speed) and the thickness and thermal conductivity of the base sheet 31 are different depending on conditions such as. According to the experiment of the present inventor, when the temperature is approximately 80 to 160 ° C., the toner 71 does not adhere to the paper 72, that is, the toner 71 can be peeled off by scratching, and can be stuck to the fixing belt 77 or remain as powder. It is preferable because there is no such problem as peeling (peeling off without scratching) or so-called fixing failure of a copying machine. The temperature of the fixing roller 73 that achieves such a temperature is, for example, 200 ° C.
(Embodiment 2)
FIG. 5 is a schematic sectional view of a scratch printed matter 3a according to another embodiment of the present invention. The scratch printed matter 3a is similar to the scratch printed matter 3 shown in FIGS. 1 and 2 described above, and corresponding portions are denoted by the same reference numerals and description thereof is omitted. It should be noted that, in the scratch printed matter 3a, a resin layer 35 which is easy to peel off from the film layer 33 is further provided on the film layer 33 serving as an anchor layer which prevents information such as the lottery number 55 from being scraped off. Formed, and the shielding layer 34 is formed on the resin layer 35.

Therefore, the peeling layer 34 made of the toner 71 is more easily peeled, and the peeling (scratch) remaining (unevenness) is reduced, which is particularly suitable for a scratch art described in a third embodiment described later. The resin layer 35 is made of a silicone resin, and may be formed by attaching a silicone resin film or applying a silicone resin. In the case of pasting, the laminator pasting machine 42 can be used again after the film layer 33 is formed. On the other hand, in the case of coating, a laminator pasting machine 42 is used, and at the outlet of the laminator pasting machine 42, a cloth impregnated with a silicone resin liquid is brought into contact with the base sheet 31 on which the film layer 33 is pasted. It can be carried out by applying, and in particular, equipment such as a coating machine is not necessary.
(Embodiment 3)
FIG. 6 is a front view of a scratch printed matter 3b according to still another embodiment of the present invention. The scratch printed matter 3b can be created by using the structure of the scratch printed matter 3, 3a shown in FIGS. 1, 2 and 5, and the manufacturing process of FIGS. 3 and 4. The scratch printed matter 3b is an example of a scratch art, and has a feature in the shielding layer 34b. That is, in the scratch printed matter 3 described above, the desired information and / or picture formed on the toner layer 32 is a lottery number 55 that is unique information that can be individually identified. And a solid screen formed of a single color toner such as the shielding layers 34 and 59.

  On the other hand, in the case of the scratch art, an arbitrary pattern can be formed on the toner layer 32b, and an arbitrary pattern can be formed on the shielding layer 34b. In the example of FIG. 6, a uniform pattern is printed on the entire surface of the base sheet 31 as the toner layer 32b, and the pattern can be arbitrarily exposed by peeling off the shielding layer 34b. It has become. In the scratch art, the shield layer 34b does not need to be completely invisible as in the lottery number 55, and a pattern is formed by shading of a single color toner as in the scratch print 3b. Is also good. In the example of FIG. 6, the pattern is drawn in a shaded state, and the user can expose a bright pattern of the toner layer by tracing the pattern like a draft. In FIG. 6, the outer frame portion is not exposed to the shielding layer 34 b but is exposed from the beginning. In an area where the shielding layer 34 b is formed, the upper half portion is formed by the mesh before scratching. The hanging state, and the lower half part shows a state where a scratched pattern line appears.

Preferably, since the printing machine 43 is an electrophotographic printer, the shielding layer 34b is formed using a plurality of color toners. Of course, since the printing machine 41 is also an electrophotographic printer, any color printing can be performed. In this way, it is possible to provide an unprecedented new scratch printed matter. The film layer 33 and the shielding layers 34 and 34b may be formed in two or more sets, or may be formed on both sides of the base sheet 31.
(Embodiment 4)
FIG. 7 is an exploded perspective view of a scratch printed matter 3c according to still another embodiment of the present invention. The scratch printed matter 3c is similar to the scratch printed matter 3 shown in FIGS. 1 and 2 described above, and corresponding portions are denoted by the same reference numerals and description thereof is omitted. This scratch print 3c is also suitably used for scratch art. It should be noted that in the scratch printed matter 3, a transparent base film 31c is used instead of the base sheet 31 such as paper. Further, the toner layer 32 is formed on one surface and the shielding layer 34 is formed on the other surface, and the film layer 33 is omitted. Therefore, the manufacturing process is also constituted only by the electrophotographic printing machines (printers) 41 and 43, which are the first and second printing devices that realize the first and second printing processes.

  With such a configuration, it is possible to realize a scratch print 3c particularly suitable for scratch art. In the present embodiment, since the toner layers are formed on both surfaces of the base film 31c, if the preferable value of the sandwiching pressure 75 is substantially equal to the toner used for the toner layer 32 and the shielding layer 34, The scratch print 3c can be created using the double-sided printing function of one digital multifunction peripheral. The base film 31c may be colored as long as desired information and / or pictures on the toner layer 32 printed on the back surface can be seen through.
