Description

  The present invention relates to a printed matter in which the printing position of an invisible image can be confirmed at the position of the visible image, a printing apparatus that prints the printed matter, and a printing method.

  Some printing apparatuses use an ink ribbon as a transfer material. This printing apparatus using an ink ribbon prints an image in black and white using a black ribbon (single color ribbon), or prints an image in color using ribbons of three primary colors (yellow, cyan and magenta) There is. As a special device, an apparatus for printing a golden or silver image using a golden or silver ink ribbon has been put into practical use.

  On the other hand, in recent years, in order to prevent falsification of printed matter, an ink that develops color with light other than visible light such as ultraviolet light or infrared light (hereinafter, this light is referred to as “light other than visible light”) is used. In some cases, an image that is invisible under visible light is printed (hereinafter, this printing is referred to as an invisible image).

  Further, the printing position of the image in printing using the ink ribbon is controlled by detecting the screen position of the ink ribbon and detecting the position of the printing object (in the case of a single color ribbon, the detection of the ribbon screen position is omitted). In some cases).

  By the way, when a malfunction occurs for some reason in this position detection, the print position is shifted and an image is printed. Further, even if no malfunction occurs in the position detection, the printing position may be shifted and an image may be printed due to the disorder of the behavior of the printing object being printed.

In the case of normal printing, even if a printing position shift due to the above-described reason occurred, the printing position shift was visually confirmed, and it was determined that the printing was defective (for example, see Patent Document 1).

The taken passbooks T are transported along the transport path 3 by a plurality of transport roller pairs 2 as transport means. In the conveyance path 3, the first OCR reading unit 5, the page turning unit 6, the direct printing unit 7, the intermediate transfer printing device 8 as a printing device, and the second as reading means are arranged along the conveyance direction of the bankbook T. An OCR reading unit 9, a folding unit 14, and a wireless IC R / W unit 10 are provided.

  Further, a discharge gate 11 for switching the discharge direction of the passbooks T between the first direction and the second direction is provided on the discharge end side of the transport path 3, and normal passbooks T are accumulated in the first direction. A normal stacking unit 12 and a defective stacking unit 13 for stacking defective bankbooks are arranged in the second direction.

  FIG. 2 shows the intermediate transfer printing apparatus 8 described above.

  The intermediate transfer printing apparatus 8 is functionally configured to include an information printing unit (hereinafter referred to as a printing unit) 16 and an overcoat transfer unit (hereinafter referred to as a transfer unit) 17 as a transfer unit.

  As the printing unit 16, a thermal melt transfer printing method is adopted. That is, an intermediate transfer film 21 as an intermediate transfer material and a molten ink ribbon 22 as a transfer material are arranged so as to be sandwiched between a thermal head 19 as a printing head and a platen roller 20, and these intermediate transfer film 21 and molten ink ribbon 22 are arranged. To print information on the surface of the intermediate transfer film 21.

  Features of this hot melt transfer method include high image durability and relatively easy application of functional materials to ink materials (eg fluorescent pigments, aluminum vapor-deposited thin films). Suitable for printed materials.

  The base film thickness and the ink layer thickness of the molten ink ribbon 22 are extremely important parameters for print dot reproducibility, and the total thickness of the ink ribbon is 3 to 25 μm, and preferably 4 to 10 μm.

  On the other hand, the thickness of the base film (to be described later) of the intermediate transfer film 21 and the total image receiving / adhesion thickness are parameters that affect the adhesiveness and film breakage characteristics. The thickness is preferably 25 to 50 μm.

  The platen roller 20 is a roller using a hard rubber material on the surface, and the reproducibility of minute dots improves as the rubber hardness increases. On the other hand, the optimum positional relationship between the platen roller 20 and the thermal head 19 can be obtained. It becomes difficult. For this reason, hardness is 75 degrees or more, desirably 85 to 97 degrees. In addition, the surface roughness of the polished rubber surface also improves the reproducibility of minute dots as the surface smoothness increases. For this reason, the surface roughness is required to be about 1 μm or less, preferably about 0.5 μm, as the center line average roughness Ra.

  In general, the driving force for conveying the intermediate transfer film 21 is often provided with a driving mechanism on the platen roller 20, but the friction coefficient between the intermediate transfer film 21 and the platen roller 20 does not increase due to the hardness and smoothness described above. Not stable.

  For this reason, a film driving roller 23 is separately provided immediately downstream (on the heat roller side) of the platen roller 20. The film driving roller 23 is a roller having a hardness of 30 to 60 degrees, and the intermediate transfer film 21 should have a winding angle as large as possible with respect to the film driving roller 23. In the embodiment, the tensioner 24 is arranged so as to obtain a winding angle of 90 ° to 130 °.

  The tensioner 24 is provided with a spring mechanism (not shown), and tension is applied to the intermediate transfer film 21 within a limited movable range so that the film driving roller 23 and the intermediate transfer film 21 are always in proper contact with each other.

  The film drive roller 23 is accurately conveyed by a combination of a five-phase stepping motor, a timing belt, and a speed reduction mechanism using a pulley. The thermal head 19 is preferably a near-edge or corner-edge type head, and it is desirable to perform printing by peeling when heated.

  The transfer unit 17 includes a heat roller 35 and a backup roller 36 that are disposed to face each other via the bankbook transport path 3. The heat roller 35 can be accurately driven at a constant speed by a DC servo motor or a stepping motor, and a pressure generated by a coil spring 37 is applied between the heat roller 35 and a rotatable backup roller 36. .

  First and second reading optical systems 5 and 9 are connected to the optical character recognition unit 69. The wireless IC read / write unit 73 is connected to the wireless IC R / W unit 10.

  Next, the operation of the passbook printing apparatus 1 configured as described above will be described.

  First, only one passbook T is taken out from the passbook taking-in section 4 shown in FIG. 1 and conveyed to the page turning section 6 (conveying process). Here, the cover of the passbook T is rolled up to a predetermined page. Will be open. Thereafter, the unique information 42 assigned to each passbook T is read by the first OCR reading unit 5 (reading step), and recognition processing is performed as described later. The recognized unique information 42 is added to the security information and becomes black print data transferred to the thermal head 19.

  On the other hand, at this time, as shown in FIG. 2, the intermediate transfer film 21 is unwound from the delivery-side reel 32, and a mark indicating the hologram position is detected by the sensor 33. Using this mark detection result, the intermediate transfer film 21 is controlled to the printing start position.

  Next, specific print information (hereinafter referred to as security information) or the like is printed at a predetermined position of the intermediate transfer film 21 by the thermal head 19. The information to be printed is color printing by superimposing four colors of black ink in addition to the three primary colors of Y (yellow), M (magenta), and C (cyan), as will be described later. These multi-color overlay printing is performed by the intermediate transfer film 21 reciprocating the thermal head 19 as many times as the number of colors. In addition, the information to be printed is a reverse image.

  The intermediate transfer film 21 on which the security information is printed in this way is wound in the forward direction (the direction of the heat roller 35), and the intermediate transfer film is detected by the transfer portion mark detection sensor 39 in the middle of the path as shown in FIG. The position of 21 is grasped. Based on this grasping result, the intermediate transfer film 21 is sent to the transfer start position.

  At this time, the passbook T is taken in as shown in FIG. 6B in a state where the page to be transferred is opened, and is conveyed to a predetermined position with respect to the heat roller 35. The page to be transferred may be a cover-back page or another medium page.

  The corresponding pages of the intermediate transfer film 21 and the passbook T thus positioned with respect to each other are overlapped with the rotation of the metal heat roller 35 having a shape in which a part of the circumference is notched as shown in FIG. And is heated under pressure along with the conveyance. Thereafter, as shown in FIG. 7, the transfer film base 26 is pulled up at an angle of 60 ° to 110 ° with respect to the bankbook T, and the transfer of the security information 46, the image receiving / adhesive layer 29, and the hologram layer 28 is completed, As shown in FIG. 8, the unique information 42, the security information 46 including the unique information 42, and the face image 44 of the owner are transferred and printed (printing process). The passbook T for which the transfer printing is completed is conveyed to the next second OCR reading unit 9 with the page being opened as shown in FIG.

  On the other hand, the unique information 42 (characters in this case) of the passbook T read by the first OCR reading unit 5 is recognized by the optical character recognition unit 69 and the recognition result is transmitted to the printing apparatus control unit 58. Is done. In the printing apparatus control unit 58, the passbook-specific information is included in the face image data of the holder acquired by the image input unit 56 sent from the data input control unit 50, the security character information of the holder input by the operation panel 55, and the like. Processing is performed by adding print data based on the character information, and print data is generated by the generation unit 58a (generation process) and transmitted to the intermediate transfer image processing unit 68. As a result, the security information 46 to which the passbook-specific information 42 a is added is printed on the surface of the intermediate transfer film 21. The passbook type specific information 42a and the security information 46 are transferred to the passbook type T and conveyed to the second OCR reading unit 9 and read as described above. The read unique information 42 a and security information 46 are recognized by the optical character recognition unit 69, and the recognition result is transmitted to the printing apparatus control unit 58. In the printing apparatus control unit 58, data discrimination processing is performed by the discrimination unit 58 b (discrimination process), and the judgment result is transmitted to the booklet transport control unit 61.

  If it is determined that the data collation result in the determination unit 58b is defective, the printing apparatus control unit 58 notifies the data input control unit 50 that the created passbook is defective. The data input control unit 50 transmits the same print processing command to the printing apparatus control unit 58 again based on receiving the notification that the created passbooks are defective, and automatically recreates the passbooks. Let it be done.

  The passbook transfer / control unit 61 controls the transfer to the normal passbook stacking unit 12 if it is a normal passbook, and to the defective passbook stacking unit 13 if it is a defective passbook. In the wireless IC R / W unit 10, data indicating that the bankbook is defective is recorded in the wireless IC 43 of the bankbook T when the wireless IC R / W unit 10 determines that it is defective.

  If the data collation result in the determination unit 58b is correct, the passbook-specific information 42 read by the first OCR reading unit 5 is used as described in the printing operation of the intermediate transfer printing apparatus 8 described above. The optical character recognition unit 69 recognizes and transmits the recognition result to the printing apparatus control unit 58. Therefore, in the printing apparatus control unit 58, the face image data of the owner acquired by the image input unit 56 and the security character information of the owner input by the operation panel 55 sent from the data input control unit 50 are used. Processing is performed by adding record data based on character information unique to the passbook, and record data to the wireless IC is generated and transmitted to the wireless IC R / W control unit 73. As a result, the security information to which the passbook type specific information is added is recorded (written) in the wireless IC 43 of the passbook type T by the wireless ICR / W unit 10.

  Incidentally, the molten ink ribbon 22 used in the above-described intermediate transfer printing apparatus 8 is configured as shown in FIG.

  That is, black ink 22B, yellow ink 22Y, magenta ink 22M, and cyan ink 22C as the first colorant that can be visually or readable under visible light are applied to the molten ink ribbon 22 along the winding direction of the molten ink ribbon 22. Repeatedly applied. Reference numeral 22S denotes an adhesive layer for adhering and positioning the molten ink ribbon 22 to the intermediate transfer film 21.

  In addition, a fluorescent ink 22K as a second colorant that cannot be viewed or read under visible light is applied to the screen on which the yellow ink 22Y of the molten ink ribbon 22 is applied. The fluorescent ink 22K does not emit light with visible light, but emits light with light other than visible light. The yellow ink 22Y and the fluorescent ink 22K are applied so as to be adjacent to each other by dividing the same screen into two.

  At the time of the above printing, as shown in FIG. 8, the face image 44 printed on the passbooks T is printed using the fluorescent ink 22K. Therefore, the face image 44 is not visible under visible light, and it is possible to prevent forgery and alteration of the printed matter. When the face image (hereinafter referred to as a stealth image) 44 is printed, the yellow ink 22Y applied on the same screen as the fluorescent ink 22K is transferred together and a cross-shaped visible image (hereinafter referred to as a mark image) as shown in FIG. 44a) are printed in parallel. The mark image 44 a is printed with a specific positional relationship in a state adjacent to the stealth image 44. Therefore, the position of the stealth image 44 can be confirmed by viewing the mark image 44a.

  In addition, after printing, the passbook T is conveyed to the second OCR reading unit 9, and the mark image 44 a is read with visible light in the second OCR reading unit 9. The read information of the mark image 44 a is recognized by the optical character recognition unit 69, and the recognition result is transmitted to the printing apparatus control unit 58. In the printing apparatus control unit 58, the determination unit 58 b determines whether or not the mark image 44 a is in a normal position (determination step), and transmits the determined result to the booklet conveyance control unit 61.

  Based on the discrimination result of the discriminating unit 58b, the passbook transport / control unit 61 judges that the stealth image 44 is also in the normal position when it is determined that the landmark image 44a is in the normal position. If the mark image 44a is determined not to be in the proper position, the stealth image 44 is determined not to be in the correct position and is controlled to be transferred to the defective passbook information stacking unit 13.

  If it is determined that the stealth image 44 is not in the proper position, the wireless IC R / W unit 10 does not immediately transfer and accumulate the passbooks T to the defective passbook stacking unit 13, but the bad passbooks. Is recorded in the wireless IC 43 of the book T, and then transported and accumulated in the defective bankbook accumulating unit 13.

  As described above, according to this embodiment, since the stealth image 44 and the mark image 44a are printed on the passbook T with a specific positional relationship, the mark image 44a is read visually or optically. Thus, the position of the stealth image 44 can be confirmed.

  Therefore, it is possible to confirm the position of the stealth image 44 without irradiating ultraviolet rays or the like, and it is safe and there is an advantage that the cost can be reduced because a light source such as ultraviolet rays is not particularly required.

  10 to 12 show another embodiment of the present invention.

  In the above embodiment, the color ink ribbon 22 is used for printing on the passbooks T. In this embodiment, the stealth image 104 and the mark image 104a are printed on the card 102 as a printed matter using the single color ink ribbon 101. Print.

  FIG. 10 is a perspective view showing a single-color ink ribbon 101. The ink ribbon 101 includes a black ink 101B that can be seen under visible light as a first colorant, and a second colorant that cannot be seen under visible light. The fluorescent ink 101K is applied in parallel in the winding direction of the ink ribbon 101.

  At the time of printing, as shown in FIG. 11, the card 102 is conveyed between the print head 106 and the platen roller 107. When the card 102 reaches between the thermal head 106 and the platen roller 107 as a print head, the print head 106 is The ink is pressed against the card 102 via the ink ribbon 101, and the print head 106 generates heat according to the image information, whereby the black ink 101B is transferred to the card 102 and a cross-shaped mark image 104a is printed, and the fluorescent ink 101K. Is transferred to the card 102 and the stealth image 104 is printed.

  Also in this embodiment, the position of the stealth image 104 can be confirmed by visually observing the mark image 104a or by reading it with the second OCR reading unit 9, as in the above-described embodiment.

  Further, in each of the embodiments described above, the mark images 44a and 104a are printed adjacent to the stealth images 44 and 104 in the horizontal direction. However, the mark images 44a and 104 and the stealth images 44 and 104 are not limited to this. Can be printed in a state adjacent to the stealth image 44 in the vertical direction or oblique direction.

  Further, the shape of the mark images 44a and 104 is not limited to a cross shape, and may be a round shape, a square shape, or the like.

  Of course, the present invention can be variously modified within the scope of the gist thereof.
