(2. Manufacturing method of booklet 10)
Next, a method of manufacturing the booklet 10 will be described. FIG. 3 is a diagram schematically showing an example of a manufacturing apparatus 20 used to manufacture the booklet 10. The manufacturing apparatus 20 manufactures the booklet 10 by carrying out the processing described later in-line while conveying the roll papers 11 and 12 fed from the rolls 21a to 21g.

FIG. 4A shows an example of the roll paper 11. The roll paper 11 is for forming the page 111 of the normal page portion 110 in the booklet 10. In this embodiment, the image of page 111 is printed on the roll paper 11 in advance, and perforations 140 are also formed at the time of printing the image. A plurality of images of the page 111 are printed so as to be arranged along the longitudinal direction of the roll paper 11 (corresponding to the transport direction of the roll paper 11 in the manufacturing apparatus 20).

On one side in the width direction orthogonal to the longitudinal direction of the roll paper 11, a binding portion 130 for gluing the booklet 10 by a process described below is set in a line shape along the longitudinal direction of the roll paper 11. .. The perforations 140 are formed along the direction of the binding portion 130 in the vicinity of the binding portion 130.

In the present embodiment, in the booklet 10, two pages of roll paper 11 of the normal page section 110 on the front side of the divided page section 120 and two pages of roll paper 11 of the normal page section 110 on the back side of the divided page section 120. Is prepared in advance. These roll papers 11 are wound around rolls 21d to 21g in the subsequent stage (corresponding to the right side of FIG. 3) of the manufacturing apparatus 20 in consideration of page order.

FIG. 4B is an example of the roll paper 12. The roll paper 12 is for forming the pages 121 of the divided page section 120 in the booklet 10. In this embodiment, the image of each portion 122 of the page 121 is printed on the roll paper 12 in advance, and the perforations 140 are also formed when the image is printed.

A plurality of images of each portion 122 of the page 121 are printed so as to be arranged along the longitudinal direction of the roll paper 12 (corresponding to the transport direction of the roll paper 12 in the manufacturing apparatus 20).

Similar to the above, on one side portion of the roll paper 12 in the width direction, a binding portion 130 for binding the booklet 10 by gluing is set in a line along the longitudinal direction of the roll paper 12 in a process described later. The perforations 140 are formed along the direction of the binding portion 130 in the vicinity of the binding portion 130.

In this embodiment, the roll paper 12 for three pages of the divided page unit 120 is prepared in advance. These roll papers 12 are wound around the rolls 21a to 21c in the preceding stage (corresponding to the left side of FIG. 3) of the manufacturing apparatus 20 in consideration of the page order.

In the manufacturing apparatus 20 shown in FIG. 3, first, an adhesive is applied by the applying section 27 to the binding section 130 of the roll paper 12 fed from the roll 21a, and gluing is performed.

The roll paper 12 is superposed on the roll paper 12 fed from the roll 21b by a pair of upper and lower rollers 22a, and is bonded by an adhesive material. At this time, the positions of the perforations 140 and the portions 122 of the page 121 correspond to both roll papers 12.

The pasted roll paper 12 is further pasted with the roll paper 12 delivered from the roll 21c by a pair of upper and lower rollers 22b in the same manner as described above.

The roll paper 12 thus bonded together is cut by the cutter 23. The cutter 23 forms a notch 150 in a direction substantially orthogonal to the binding portion 130 so that the tip on the binding portion 130 side exceeds the perforation 140 and reaches a position between the perforation 140 and the binding portion 130. This state is shown in FIG. The cut 150 is formed at a position where one page 121 is divided into three parts 122.

After that, the manufacturing apparatus 20 applies the adhesive material to the binding portions 130 on the front and back surfaces of the pasted roll paper 12 by the application portion 27 and performs gluing.

Then, the roll paper 11 fed from the roll 21d is superposed on the front side of the roll paper 12, the roll paper 11 fed from the roll 21e is superposed on the back side of the roll paper 12, and the pair of upper and lower rollers 22c rolls the roll paper 11 together. , 12 are pasted together. At this time, the perforations 140 of the roll papers 11 and 12 and the positions of the pages 111 and 121 correspond to each other.

Hereinafter, after the roll paper 11 fed from the rolls 21f and 21g is further bonded by a pair of upper and lower rollers 22d in the same manner as described above, a cutter 25 is used to cut the roll papers 11 and 12 on both sides in the width direction of FIG. The cutting line 250 shown in b) is cut to separate unnecessary portions from the booklet 10.

Finally, the cutting line 260 shown in FIG. 5C is cut by the cutter 26, and the plurality of roll papers 11 and 12 are cut into the size of one page of the booklet 10 to manufacture the booklet 10 described above. It

Although the positions of the cutting lines 250 and 260 on the roll paper 11 are shown in FIGS. 5B and 5C, the positions of the cutting lines 250 and 260 on the roll paper 12 therebelow are shown in FIG. 6 respectively. It becomes like (a) and (b).

This booklet 10 can be easily manufactured because no metal fitting such as a ring or a wire is required for binding the booklet 10, and the division of the page 121 can be performed at the time of bookbinding continuously with the steps of gluing, pasting and the like, so that the process load is small.

As described above, since the montage-like booklet 10 of the present embodiment is glued and bound, no metal fittings are required for bookbinding, and the booklet 10 can be easily manufactured by performing gluing and binding work continuously in the manufacturing process. In addition, by placing the perforations 140 in the folds near the binding portion 130, the booklet can be easily opened. Further, the divided portion 122 of the page 121 can be easily separated simply by cutting along the perforations 140, and can be used as a cash voucher, a gift certificate, a coupon ticket, or the like. Further, the notch 150 that divides the page 121 is provided so as to extend beyond the perforation 140, so that even if the position where the notch 150 is formed varies in the manufacturing process, the tip of the notch 150 can surely reach the perforation 140. Thus, the divided portion 122 of the page 121 can be separated cleanly.

In addition, since the booklet 10 of the present embodiment does not use metal fittings such as a ring and a wire, it is easy to recycle, which is also preferable in terms of environment. Further, it is possible to make the booklet 10 thin and put it in an envelope for mailing. It can also be used as a magazine appendix.

Furthermore, in this embodiment, the divided page section 120 can be protected by the normal page section 110 by binding the divided page section 120 inside the normal page section 110.

Further, according to the above-described manufacturing method, the booklet 10 can be easily manufactured by using the roll papers 11 and 12, and it is also possible to apply a conventional manufacturing line for business forms for printing forms and the like.

However, the present invention is not limited to this. For example, the number of pages of the normal page section 110 and the divided page section 120 of the booklet 10 is not limited to the above-mentioned number, and may be any number of pages including at least one page of the divided page section 120. It is also possible to form a booklet with only the divided page section 120.

The manufacturing process also changes according to the difference in the form of the booklet 10. For example, in this embodiment, the roll paper 12 is attached to another roll paper 12, and then the notch 150 is formed by the cutter 23. When the number of pages 120 is only one, the roll paper 12 is cut with the cutter 23 to form the cut 150, and then the roll paper 12 is attached to another roll paper 11. Further, in the present embodiment, the booklet 10 is manufactured using the roll papers 11 and 12 on which the perforations 140 are formed in advance, but the perforations 140 are formed on the roll papers 11 and 12 during the manufacturing process described above. It is also possible.

Further, as the usage of the booklet 10, as described above, the portion 122 of the page 121 of the divided page portion 120 is used as a cash voucher, a gift certificate, a coupon ticket, or the like, and the portion 122 is cut to be a usable calendar or the like. You can also Also, menus such as main dishes and side dishes of restaurants can be printed on each part 122 and used as a menu catalog in which these combinations can be freely studied, or each part 122 can be printed with upper and lower parts of clothes and It can also be used as a booklet for fashion coordination in which combinations can be considered. It is also possible to print still images such as facial expressions above and below each part 122 and use it as a booklet for picture matching where you can enjoy various facial expressions by picture matching. Learning to print problems, answers and explanations in each part 122 It can also be used as a booklet.

[Second Embodiment]
As described above, in the booklet 10 according to the present invention, the divided portion 122 of the page 121 can be cut off and used as a cash voucher, a gift certificate, a coupon ticket, or the like. It is also possible to apply.

Therefore, in the second embodiment, at least one of the divided portions 122 of the page 121 is subjected to the forgery prevention technique using a latent image as described in Japanese Patent No. 5692663, and FIG. ), the latent image portion 170 and the background portion 160 which is a peripheral portion of the latent image portion 170 are printed and formed on the portion 122. Although illustration is omitted, a printed pattern corresponding to a cash voucher, a gift certificate, a coupon ticket, or the like is also formed on the portion 122.

The latent image portion 170 is an area in which the printed matter (portion 122 into which the page 121 is divided) looks like the background portion 160 and cannot be discriminated from one another, but the latent image portion 170 appears so as to be discriminable from the background portion 160 only when copying. In FIG. 7A, the latent image portion 170 is indicated by a dotted line for convenience of explanation.

When the portion 122 is copied, as shown in FIG. 7B, the latent image portion 170 has a lower density than the background portion 160 in the copy 122 ′. In this way, the latent image portion 170 becomes thin and distinguishably appears in the copy 122', and it can be seen that it is a copy 122' (counterfeit), so that the copy is restrained and a counterfeit prevention effect is achieved.

FIG. 8 is an enlarged view showing the background portion 160 and the latent image portion 170. As shown in the figure, the background portion 160 is formed in a line shape by arranging a plurality of substantially parallel image lines 161 at a predetermined interval D at equal intervals. In the background portion 160, the image line 161 can be reproduced by a copying machine due to factors such as the thickness W1 of the image line 161 and the interval D that are sufficiently larger than a certain value.

Note that the thickness W1 of each drawing line 161 of the background portion 160 is the same. The thickness W1 of the drawing line 161 indicates the width of the drawing line 161 in the short side direction, and the long side direction of the drawing line 161 that is substantially orthogonal to the short side direction in the plane is the length direction of the drawing line 161. The distance D between the image lines 161 is the distance between the center lines of the image lines 161. The same applies to the image line 171 of the latent image portion 170.

The latent image portion 170 forms a row 172 by arranging a plurality of substantially parallel image lines 171 at a predetermined interval DL along the length direction of the image line 161 of the background portion 160 at regular intervals. Are arranged at regular intervals DH along the arrangement direction of the image lines 161 of the background portion 160. The arrangement direction of the image lines 161 of the background portion 160 is a direction substantially orthogonal to the length direction of the image lines 161 in a plane.

The image line 171 of the latent image portion 170 is substantially orthogonal to the image line 161 of the background portion 160 in a plane, and the row 172 of the image line 171 of the latent image portion 170 is formed along the extension of the image line 161 of the background portion 160. To be done. The image lines 171 of the latent image portion 170 cannot be completely reproduced by the copying machine due to factors such as the interval DL being less than a predetermined value and exceeding the resolution performance of the scanner or printer of the copying machine. ing.

The thickness W2 and the length H of each image line 171 of the latent image portion 170 are the same, and the image line 171 is formed by the ink of the same color as the image line 161. Further, the distance DH between the rows 172 in the latent image portion 170 is the distance between the center portions of the image lines 171 in each row 172 in the length direction. The center portion is on the extension of the center line of the image line 161 of the background portion 160, and therefore the interval DH has the same value as the interval D of the image line 161.

For such a printed matter, it is important that the latent image portion 170 can be discriminated in the copy 122′, but in consideration of good appearance, the background portion 160 and the latent image portion 170 are evenly formed in the printed matter. It is also important that it can be seen and cannot be visually discerned.

For that purpose, it is usually considered that the area ratio of the image line 161 of the background portion 160 and the area ratio of the image line 171 of the latent image portion 170 are the same. It is more difficult for the background portion 160 and the latent image portion 170 to be discriminated in the printed matter when the area ratios of the image lines 161 and 171 of the image portion 170 are the same as in the case where the area ratios are not the same as in the case of a predetermined condition. , And the finding that it is more preferable was obtained.

That is, in the present embodiment, as the above-described predetermined condition, the area ratio Ab of the image line 161 of the background portion 160 is set to W1/D using the thickness W1 of the image line 161 and the interval D, and the image of the latent image portion 170 is displayed. The area ratio Al of the line 171 is expressed as (W2·H)/( using the thickness W2 of the image line 171, the length H of the image line 171, the interval DH of the row 172, and the interval DL of the image line 171 in the row 172. DH/DL), the ratio R (=Al/Ab) of the area ratio Al of the image line 171 of the latent image portion 170 divided by the area ratio Ab of the image line 161 of the background portion 160 is about 1.11. Above and above 1.33.

Further, in the present embodiment, the area ratio Ab of the image line 161 of the background portion 160 and the area ratio Al of the image line 171 of the latent image portion 170 are set to about 25.0% or less, and a printed pattern such as a gift certificate, a cash voucher, or a coupon ticket is printed. Do not affect the appearance of.

Although details will be described later, in this embodiment, the value R (=Al/Ab) of the ratio of the area ratio Al of the image line 171 of the latent image portion 170 to the area ratio Ab of the image line 161 of the background portion 160 is calculated as described above. By setting the area ratio Al of the image line 171 of the latent image portion 170 to a value slightly higher than that of the background portion 160, the difference between the background portion 160 and the latent image portion 170 can be more determined. It can be difficult to do. On the other hand, in the copy 122', the latent image portion 170 can be discriminated, the forgery prevention effect is exhibited, and the appearance is good. Further, by forming the background portion 160 and the latent image portion 170 with the image lines 161, 171, plate making is easy.

Further, in the present embodiment, the area ratio Ab of the image line 161 of the background portion 160 and the area ratio Al of the image line 171 of the latent image portion 170 are set to about 25.0% or less so that a printed pattern such as a gift certificate or a cash voucher can be seen. The background portion 160 and the latent image portion 170 can be thinly provided so as not to affect. More specifically, as will be described later, for example, the area ratio Ab of the image line 161 of the background portion 160 is about 11.4% or more and about 20.0% or less, and the area ratio Al of the image line 171 of the latent image portion 170 is about 14.3%. By setting it to the above and about 23.8% or less, it is possible to provide the background portion 160 and the latent image portion 170 so as not to affect the appearance of the printed pattern, and to obtain the above-mentioned effect. However, the range of the area ratio Ab, Al is not limited to this, even if the area ratio Ab, Al is another range, the value R of the ratio of the area ratio Al divided by the area ratio Ab is about 1.11 or more and If it is about 1.33 or less, the above effect can be achieved.

Further, in the present embodiment, the image line 171 of the latent image portion 170 is made substantially orthogonal to the image line 161 of the background portion 160 in the plane, and the row 172 of the image line 171 of the latent image portion 170 is set to the image line 161 of the background portion 160. By forming along the extension, it is difficult to discriminate the difference between the background portion 160 and the latent image portion 170 in the printed matter, which contributes to making the latent image portion 170 discernable in the copy 122 ′. However, the arrangement of the image lines 161 and 171 is not limited to this.

Next, the results of examining the above-mentioned forgery prevention technique for the printed matter (the portion 122 obtained by dividing the page 121) will be specifically described as an example. However, the present invention is not limited to this.

[Printed matter]
As an example, the thickness W1 of the image line 161 of the background portion 160 and the length H of the image line 171 of the latent image portion 170 are adjusted, and the area ratio Al of the image line 171 of the latent image portion 170 is set to the background portion 160. Printed materials C, H, I, and N in which the ratio value R(=Al/Ab) divided by the area ratio Ab of the image line 161 of about 1.11 or more and about 1.33 or less were produced.

Further, the area ratio Ab of the image line 161 of the background portion 160 and the area ratio Al of the image line 171 of the latent image portion 170 are set to about 25.0% or less in any of the printed materials C, H, I, and N. Specifically, in the printed materials C, H, I, and N, the area ratio Ab of the image line 161 of the background portion 160 is about 11.4% or more and about 20.0% or less, and the area ratio Al of the image line 171 of the latent image portion 170 is Al. Is about 14.3% or more and about 23.8% or less.

In addition, as a reference example, the thickness W1 of the image line 161 of the background portion 160 and the length H of the image line 171 of the latent image portion 170 are adjusted, and the value R of the ratio is in the range of about 1.11 or more and about 1.33 or less. Different printed materials A, B, D, E, F, G, J, K, L, and M were produced.

The distance D between the image lines 161 of the background portion 160, the thickness W2 of the image lines 171 of the latent image portion 170, the distance DH between the columns 172, and the interval DL between the image lines 171 in the column 172 are common to the printed materials A to N. As the latent image portion 170, the character “copy” was formed.

Regarding the above-mentioned printed materials A to N, the thickness W1 of the image line 161 and the interval D of the background portion 160, the thickness W2 and the length H of the image line 171 of the latent image portion 170, the interval DH of the column 172, and the image in the column 172. The interval DL of the line 171 (above, all units are mm), the area ratio Al of the image line 171 of the latent image portion 170, the area ratio Ab of the image line 161 of the background portion 160, and the ratio value R (=Al/Ab ) Is shown in FIG.

Here, the thickness W1 of the image line 161 of the background portion 160 is changed in four steps (0.04, 0.05, 0.06, 0.07 mm), and the length H of the image line 171 of the latent image portion 170 is set in four steps (0.10, 0.15, 0.20, 0.25 mm) to produce 14 printed materials A to N having different ratio values R (=Al/Ab) described above, and in FIG. S1 and the length H of the image line 171 of the latent image portion 170, the area ratio Al of the image line 171 of the latent image portion 170, the area ratio Ab of the image line 161 of the background portion 160 for the corresponding printed materials A to N, And the ratio value R (=Al/Ab).

The distance D between the image lines 161 of the background portion 160, the thickness W2 of the image lines 171 of the latent image portion 170, the distance DH of the column 172, and the interval DL of the image lines 171 of the column 172 are the same for the printed materials A to N. D=0.35 mm, W2=0.05 mm, DH=0.35 mm, DL=0.15 mm.

[Difficulty of distinguishing between the background portion 160 and the latent image portion 170 in the printed matter]
10, 11 and 12 are examples in which printed materials C to N are printed on OCR paper, coated paper, and fine paper, respectively, and the horizontal axis indicates the thickness W1 of the image line 161 of the background portion 160 W1=0.04, 0.05, 0.06. , 0.07 (mm), and the vertical axis is the length H of the image line 171 of the latent image portion 170 H=0.15, 0.20, 0.25 (mm), and the printed materials C to N are shown at the corresponding positions.

When the present inventor actually observed these printed matters C to N, the printed matter C, H, I, and N in which the value of R described above was in the range of about 1.11 or more and about 1.33 or less had a value of R The result is that the character "copy" of the latent image portion 170 is more difficult to distinguish from the background portion 160 than the printed materials D, E, F, G, J, K, L, and M having values outside the range. Although not shown in FIGS. 10 to 12, the printed materials A and B have the same tendency as the printed materials D, E, F, G, J, K, L, and M.

In the printed matter D, the area ratio Ab of the image line 161 of the background portion 160 and the area ratio Al of the image line 171 of the latent image portion 170 are equal, and the value of R is 1.00. The printed materials C, H, I, and N in which the area ratio Al of the image line 171 of the image portion 170 is slightly higher than that of the background portion 160 were more difficult to discriminate the characters of “copy” in the latent image portion 170.

[Possibility of distinguishing the latent image portion 170 in a copy]
Next, each of the printed materials A to N was color-copied on an OCR paper, and the possibility of distinguishing the latent image portion 170 in the copied material was examined. For copying, three types of copying machines, ApeosPort-VC7780 manufactured by Fuji Xerox Co., Ltd., iR ADV 5255 and iR ADV 7065 manufactured by Canon Inc., were used.

13, 14 and 15 are prints C through ApeosPort-VC7780 (copier I) manufactured by Fuji Xerox Co., Ltd., iR ADV 5255 (copier II) and iR ADV 7065 (copier III) manufactured by Canon Inc., respectively. N is a copy, and the horizontal axis is the thickness W1 of the image line 161 of the background portion 160 W1=0.04, 0.05, 0.06, 0.07 (mm), and the vertical axis is the length of the image line 171 of the latent image portion 170. H=0.15, 0.20, and 0.25 (mm) are shown at the corresponding positions of the copies of the printed materials C to N.

When the present inventor actually observed the copies of the printed materials C to N, the latent image portion 170 of each of the copied materials including the copies of the printed materials C, H, I, and N, although there were differences in degree, The character "copy" could be identified. It should be noted that although the illustration of the copies of the printed materials A and B is omitted in FIGS. 13 to 15, the characters “copy” could be similarly identified. Similar results were obtained when the OCR paper was replaced with coated paper or high-quality paper.

From the above, the ratio R of the area ratio Al of the image line 171 of the latent image portion 170 divided by the area ratio Ab of the image line 161 of the background portion 160 is about 1.11 or more and about 1.33 or less. , N are more difficult to distinguish because the background portion 160 and the latent image portion 170 look uniform, and the latent image portion 170 can be discriminated in the copy, which has an anti-counterfeiting effect and is a suitable printed matter with a good appearance. It was confirmed that
