Description

  The present invention relates to a photobook manufacturing method, and more particularly, to a photobook manufacturing method suitable for on-demand having excellent printed surface durability and surface gloss.

  In recent years, photo quality prints that can be printed quickly in stores, and photobooks that can be printed as personal photobooks that can be printed like a high-quality photobook by editing the layout of digitized photo information on a personal computer, etc. Service is progressing.

Many of such photobooks are manufactured after a printing process in which intermittent printing is performed for each printing paper, a collating process in which pages are aligned, and a finishing process in which bookbinding is performed.
Conventional photobooks use an intermediate transfer member such as a rubber blanket or a roll plate cylinder, so a certain number of copies are required for ordering. This makes it possible to produce a high-quality photo book for the general public even for individual orders from a single volume. For example, Patent Document 1 discloses a photobook creation method.

The manufacturing method for intermittent printing for each printing paper has a problem that it is difficult to align pages in the collating process. In order to solve such a problem, a recording paper on which a plurality of photographic images are printed in series is folded in a bellows shape so that the back side where the photographic image opposite to the printed side of the photographic image is not formed is not exposed. By fixing in such a manner, a photo book has been developed that allows a photograph image to be browsed as if each page of the book was scrolled (see Patent Document 2).
In addition, the above-described bellows-like photobook has a problem in the finishing condition due to the bulging of the folded portion, and a technique for solving such a problem has also been known (see Patent Document 3).
In the current printing industry, since the printing price is charged in proportion to the long length, continuous printing has a problem that the manufacturing cost increases.
In addition, since a certain degree of hardness is required for the substrate to be printed, it has been pointed out that it is difficult to print using a raw fabric roll.

  In addition, since current photographic prints are printed directly on the surface of the substrate, the printed surface touches light or gas, and as a result, the photographic image is faded over time. There is a problem that the printing surface is soiled by spilling the liquid, and the photographic image is deteriorated due to fading or the like.

In addition, since direct printing is performed on the surface of the base material, high-quality paper with high surface smoothness must be used to give gloss to the printing surface, and the manufacturing price increases as the price of the base paper increases. There was a problem.
Further, when printing is performed using an ink jet, there is a problem in that the texture of the base material is exposed at a portion where the ink is not attached and the surface is not smooth because unevenness is formed on the printing surface.

  For this reason, in order to prevent fading etc. of a photographic image, a method of overcoating a protective liquid on a photographic surface after printing on a substrate is also used. This method can lower the manufacturing cost than the method of covering with the above-mentioned film, but it is necessary to frequently maintain machinery used for roller coating and gravure coating, and there is an odor of chemicals used for overcoat. The problem of remaining after bookbinding was pointed out.

Japanese Patent Laid-Open No. 9-43827 JP 2006-27121 A JP 2007-253574 A

  The present invention does not require the use of high-quality high-quality paper as a substrate to be printed, and provides a high-quality printing surface that provides a uniform gloss on the entire surface, and is excellent in surface protection, so that it can be used for a long time. It is an object of the present invention to provide a photo book having a highly durable printing surface capable of maintaining high image quality and high quality.

It is another object of the present invention to be able to manufacture a photobook that meets on-demand and has a high-quality printing surface in a shorter time than before, and to reduce the manufacturing cost as compared with the conventional one.
It is another object of the present invention to provide a photobook manufacturing method capable of posting the number of photographs according to demand without any limitation on the number of pages.

The present invention employs the following configuration in order to solve the above problems.
(1) In the present invention, after a plurality of photographic images are frame-printed on a long transparent or translucent base material so as to form an even number of two or more stages, the transparent or translucent base material is oriented in the short direction. It is folded so that the printing surface is inward at the center, an opaque core base material is inserted into the folded inner side, and the printing surface of the transparent or translucent base material is adhered to both surfaces of the core base material. After creating a counterfeit, if the even column is two-tiered, after bending the long original fabric into a bellows shape for each frame division of the photographic image, or if the even column is four or more The original fabric is folded until it is folded in a single layer at the center in the lateral direction, the long original fabric is folded into a bellows shape for each frame division of the photographic image, and then the booklet is bound by cutting the bag-like portion. This is a method for manufacturing a photobook.
Here, the non-transparent core substrate has a function of giving a certain degree of strength and preventing the back side of a photographic image printed on a transparent or translucent substrate.

  The core substrate may be subjected to double-sided lamination processing or single-sided lamination processing. When the double-sided laminating process is performed, the core base material can be sandwiched in the valley of the transparent or translucent base material. When single-sided laminating is performed, a page can be formed by laminating the laminated surfaces of the core base material when the bellows are folded. An adhesive may be used without laminating the core substrate.

  When single-sided lamination is applied to the core substrate, multiple photographic images are frame-printed on a long transparent or translucent substrate, and then the opaque core substrate and transparent or translucent substrate print surface are attached. After creating the original fabric, folding the long original fabric into a bellows shape for each frame division of the photographic image, and then backing the opposite side of the core substrate attachment surface back, The book can be bound by cutting the shaped portion.

Here, the opaque core base material has a function of giving a certain degree of strength and preventing the back side of a photographic image printed on a transparent or translucent base material. A photo book may be manufactured by forming a cover with a separate member and attaching the back.
Further, frame-by-frame printing refers to a state in which top / bottom / left / right, pages, serial numbers, and the like are printed in series so as to function as a book after bookbinding.

Here, when the even-numbered column structure is two-stage, the original fabric is bent in a bellows shape in the longitudinal direction in the original fabric state. Binding can be performed by cutting a bag-like portion (bag-like portion) across the page after folding.
Alternatively, when the even-numbered columns are four-stage, the original fabric is further bent once at the center in the lateral direction. Thereafter, bookbinding can be performed by cutting the bag-shaped portion across the page.
In addition, the photographic image referred to here may include characters, symbols, and the like as long as the photograph is mainly printed. In addition, depending on the frame, an image without a photograph (for example, composed of only characters) is also included.

Further, when the even-numbered column has six columns, the original fabric can be bent once at the center in the short direction, and then further bent once at the center in the short direction. In this state, the book can be bound by cutting a bag-like portion across the page.
If the number of even stages is 8 or more, the original fabric can be bound by cutting the bag-like portion across the page after folding back the original fabric until it becomes a single-fold double fold at the center in the short direction. it can. Here, the one-stage double fold indicates a state in which the frame divisions are connected in the longitudinal direction and appear on the front and back.
The photobook created by the above manufacturing method has a printing surface formed on the back side of a transparent or translucent substrate, so the printing surface is not affected by outside air, ultraviolet rays, etc. A highly durable printing surface capable of maintaining the quality can be obtained.
Furthermore, weather resistance with respect to permeation | transmission of the gas from the back side of a core base material can be provided by coat | covering a core base material with a transparent or semi-transparent base material from both sides.

It is a conceptual diagram for demonstrating an example of the process of a bellows folding which concerns on this embodiment.

Hereinafter, an embodiment of a photobook manufacturing method according to the present invention will be described. However, the embodiment described below is an example and does not limit the present invention.
Embodiment 1
FIG. 1 is a schematic plan view showing Embodiment 1 in which a photographic image used in the photobook manufacturing method according to the present invention is frame-divided and printed.
As shown in FIG. 1, the first embodiment is characterized in that a plurality of photographic images are divided into frames and printed on a long transparent substrate 1 in two steps. In such frame layout printing, a frame located at a corner (upper right in the figure) is defined as a back cover area (BC). Further, a frame that is adjacent in the longitudinal direction is used as a cover area (FC).
Between the back cover area (BC) and the front cover area (FC), a back cover area (BB) having a width W in accordance with the thickness of the total number of pages is formed.
Further, frames corresponding to the number of pages in the bound state are arranged as shown in FIG. On the upper frame, an image inverted by 180 ° is printed. The last page (LP) is arranged in the lower part of the back cover area (BC).

Here, as the transparent substrate 1, various materials suitable for adhesion of a film by printing and heat can be used. A translucent substrate may be used instead of the transparent substrate as long as a photographic image printed from the opposite side of the printing surface can be seen.
For example, cellulose ester or polyester is suitable. Among these, polyesters that are excellent in printing color development and have high durability are suitable.
Examples of the cellulose ester include cellulose triacetate, cellulose acetate propionate, and cellulose acetate butyrate. Examples of the polyester include polyethylene terephthalate (PET), polyamide, polycarbonate, polyimide, polyolefin, polyester, polysulfonamide, and the like. Among these, as the transparent film used in the present invention, polyethylene terephthalate (PET) having high reflectivity and excellent gloss is suitable. A matte PET film or the like may be used depending on the finish.

  As the transparent substrate, a protective layer may be appropriately formed to increase adhesion, improve glossiness / image quality, resist scratches, prevent fading, improve water resistance, improve light resistance, etc. good. Materials for forming the protective layer include polyester, polypropylene, polystyrene, polystyrene-acrylic resin, polymethyl methacrylate, polyvinyl acetate, polyolefin, poly (vinylethylenecoacetate), polyethylenecoacrylic resin, amorphous polypropylene and polypropylene. Examples thereof include a polymer and a graft copolymer.

The photographic image which concerns on this invention has the characteristics in the point in which the printing surface is formed in the sticking surface side of the transparent base material 1 and the core base material mentioned later. A reverse image can also be used as such a printing surface.
Here, the printing surface is printed using a printer, offset printing, gravure printing, or the like. In particular, in the present invention, it is preferable to use a printer in order to meet on-demand.

  As the printer, a thermal transfer method, a thermal melting type, a sublimation type, a thermal type, a discharge destruction type, an ink jet method, a dot impact method, an electrophotographic method, a type printer, or the like can be used. Among these, it is preferable to use an electrophotographic printer from the viewpoint of durability. As an electrophotographic printer, either a tandem method or a four-cycle method may be used. In particular, it is particularly preferable to use an electrophotographic printer by liquid development that can obtain a fine print surface. For example, printing using an Indigo press series manufactured by Healette Packard (HP) can be mentioned.

  As toners used for printing, charged colored fine particles that visualize electrostatic latent images, colored pigments such as carbon black, polarity control materials, and other additives are dispersed in resin to form powder toner and insulating liquid. In addition, a liquid toner in which a resin or a polarity control material is adsorbed and dispersed in a color pigment is used. Among these, liquid toner having a small particle size is preferable. A normal powder toner has a particle size of about 5 to 8 μm, whereas a liquid toner has a size of about 1 to 2 μm, and a fine printed surface can be obtained. In addition, since the liquid toner does not require a heat fixing process, it can be easily transferred and fixed without causing heat distortion in a transparent film such as PET.

  As the r-core substrate used in the present invention, various materials currently used for high-quality photographic prints are used. Such materials are not limited, but in the relationship with the transparent film of the present invention, not only coated paper such as art paper, coated paper, lightweight coated paper, cast paper, fine coated paper, but also non-coated printing paper. It may be used. In particular, since the present invention has a printing surface on the transparent film side, it has a technical feature that manufacturing cost can be suppressed without using expensive coated paper such as art paper and cast paper.

  The non-coated printing paper is a printing paper whose surface is not overcoated with a pigment or the like. However, those to which a small amount of chemicals such as starch are applied are included. Depending on the proportion of chemical pulp used, it can be divided into high-grade printing paper, intermediate-grade printing paper, lower-grade printing paper such as reprinted paper, Indian paper, thin paper, etc. Since these sheets are relatively inexpensive, the final manufacturing cost can be suppressed.

Since the present invention is characterized in that the surface of the core base material is covered with a transparent base material having a printing surface, the texture of the base material does not appear. For this reason, even if some colors and patterns are attached to the substrate, it can be used without any problem.
Alternatively, high-grade printing paper or intermediate-grade printing paper may be used as a base paper, and coated printing paper with a coating overcoated, or fine coated paper with a small amount of coating applied to the surface may be used.
Also, special printing paper such as colored fine paper, information paper such as thermal paper and copy paper may be used. The raw material may be wood pulp, synthetic paper or waste paper.
Further, polymer films such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polyester, polycarbonate, cellulose sester, polyimide, polyvinyl chloride, polyvinyl acetal, etc. may be used.

Next, the manufacturing process of the original fabric used in the photobook manufacturing method according to the present invention will be described. FIG. 2 is a partial perspective view for explaining a process of inserting the core base material into the transparent base material.
As shown in FIG. 2, the long transparent substrate 1 on which the photographic image is frame-divided and printed by the above-described process is valley-folded so that the printing surface is inward at the center in the short direction (VF in FIG. 1). The opaque core base material 2 is inserted into the folded back in this way. After inserting the core base material 2 into the transparent base material 1 folded at the center, the printing surface of the transparent base material 1 is adhered to both surfaces of the core base material 2 at appropriate positions. The first page and the like in FIG. 2 are obtained by inverting a photographic image printed on a frame.
After the original fabric manufactured in this manner is folded into a bellows shape for each frame division of the photographic image, the bag-shaped portion where the transparent substrate 1 is formed across the pages is formed. A photo book can be manufactured by cutting. The process of bending the bellows and cutting the bag-like portion will be described using other embodiments.

By using the photobook manufacturing method according to the present invention, the photographic image surface is sandwiched between the transparent substrate 1 and the core substrate 2, thereby protecting the photographic image from ultraviolet rays, gas, and scratches by the transparent substrate. can do. As a result, it is possible to maintain high image quality and high quality over a long period of time on a printed surface such as a photograph.
Moreover, since the ground color of the core base material 2 can be hidden by applying the printing surface to the entire surface of the transparent base material 1, it is not necessary to use high-quality high-quality paper as the core base material 2, and the photobook The manufacturing price can be greatly reduced.

Furthermore, the gloss by the transparent substrate 1 can give a uniform gloss to the entire surface of the photographic image, and a photo book having a high-quality printing surface that is almost the same as a gravure photo book can be manufactured.
The photo print according to the present invention can be bound immediately upon request from the customer. That is, digital printing can be performed on one side of the transparent substrate 1 by transmitting information such as photographs and characters to a printing machine.
For digital printing, it is preferable to use an electrophotographic printer. This is because such a printer is most suitable for on-demand use, without the need to create an intermediate transfer member separately.

A back cover area (BB) having a width W in accordance with the thickness of the total number of pages is formed between the back cover area (BC) and the front cover area (FC).
Further, frames corresponding to the number of pages in the bound state are arranged as shown in FIG. On the upper frame, an image inverted by 180 ° is printed. The last page (LP) is arranged at the bottom of the column in the spine area (BC).

Here, the frame next to the first front cover area (FC) has [2 ^{(n + 1)} −1] pages (where n is the number of folds to be described later). It is preferable that the frames are printed. By placing a page with such a value next to the front cover area (FC), the folding process and the bellows process, which will be described later, can be manufactured in a shorter period of time, resulting in a reduction in manufacturing cost. It can be cheaper.
Specifically, in the second embodiment, since it is folded twice as described later, since n = 2, the seventh page is rotated 180 ° in the frame adjacent to the first cover area (FC). Will be printed.

Next, the transparent base material 11 on which the photographic image is divided and printed by the above-described process is valley-folded so that the printing surface is inside at the center in the short side direction (VF1 in FIG. 3). An opaque core base material (not shown) is inserted into the folded inside. After inserting the core base material into the transparent base material 11 folded at the center, the printing surface of the transparent base material 11 is adhered to both surfaces of the core base material at appropriate positions.
In the second embodiment, in this state, the original fabric is further folded back at the center in the short direction (VF2, MF in FIG. 3) to form a one-stage double fold. After that, after the original fabric manufactured in this way is folded into a bellows shape for each frame division of the photographic image, the photobook can be manufactured by cutting the bag-like portion. . The process of bending the bellows and cutting the bag-like portion will be described using other embodiments.

As shown in FIG. 4, the third embodiment is characterized in that a plurality of photographic images are divided into eight frames on a transparent base material 21 and printed. In such frame layout printing, a frame located at a corner (upper right in the figure) is defined as a back cover area (BC). Further, a frame adjacent to the back cover area (BC) is defined as a front cover area (FC). Further, frames corresponding to the number of pages in the bound state are arranged as shown in FIG.

Here, the frame next to the first front cover area (FC) has [2 ^{(n + 1)} −1] pages (where n is the number of folds to be described later). It is preferable that the frames are printed.
Specifically, in the third embodiment, since it is folded three times as will be described later, since n = 3, the 15th page is printed on the frame adjacent to the first cover area (FC). become.
Next, the long transparent substrate 21 on which the photographic image is frame-printed by the above-described process is folded back so that the printing surface is inward in the center in the short direction. An opaque core base material (not shown) is inserted into the folded inside. After inserting the core base material into the transparent base material 21 folded at the center, the printing surface of the transparent base material 21 is stuck on both surfaces of the core base material at an appropriate position.
Next, in this state, the original fabric is further folded at the center in the short direction. In Embodiment 3, in this state, the original fabric is further folded back at the center in the lateral direction to form a one-stage double fold. After that, after the original fabric manufactured in this way is folded into a bellows shape for each frame division of the photographic image, the photobook can be manufactured by cutting the bag-like portion. . The process of bending the bellows and cutting the bag-like portion will be described using other embodiments.

Embodiment 4
FIG. 5 is a conceptual plan view showing Embodiment 4 in which a photographic image used in the photobook manufacturing method according to the present invention is divided into frames.
As shown in FIG. 5, the fourth embodiment is characterized in that a plurality of photographic images are divided into frames and printed on a long transparent substrate 31. At this time, reverse printing is performed for each job by an Indigo press (manufactured by HP). In such frame layout printing, a frame located at a corner (upper right in the figure) is defined as a back cover area (BC). Further, a frame that is adjacent in the longitudinal direction is used as a cover area (FC).

Between the back cover area (BC) and the front cover area (FC), a back cover area (BB) having a width corresponding to the thickness of the total number of pages is formed.
Further, frames corresponding to the number of pages in the bound state are arranged as shown in FIG. On the upper frame, an image inverted by 180 ° is printed. The last page is arranged in the lower part of the back cover area (BC).
Next, the manufacturing process of the original fabric used in the photobook manufacturing method according to the present invention will be described. The long transparent base material 31 on which the photographic image is frame-printed by the above-described process is valley-folded so that the printing surface is inside at the center in the short side direction (VF in FIG. 5). An opaque core base material is inserted into the folded inside. After inserting the core base material into the transparent base material 31 folded at the center, the printing surface of the transparent base material 31 is stuck on both surfaces of the core base material at appropriate positions.

The raw material thus manufactured is processed as shown in FIG. That is, the front cover area (FC) and the back cover area (BC) surround a portion folded in a bellows shape, and the right side of the bellows portion is attached to the inside of the back cover area (BB). The back side of the back cover area (BC) is the 22nd page and is bound so as to face the 21st page. As shown in FIG. 6, the frame division is connected in the longitudinal direction and appears on the front and back, that is, in a one-stage folded state.
The back side of the front cover area (FC) is the first page. The left side of the second page opposite to the first page is connected in a bag shape. In the fourth embodiment, there are five similar bag-like portions (S). Therefore, a photobook can be bound by cutting the bag-like portion (S) after bending the long original fabric into a bellows shape for each frame division of the photographic image.

Next, the raw fabric manufacturing apparatus used in the fourth embodiment will be described. FIG. 7 is a perspective view of a vertical original fabric manufacturing apparatus that can manufacture an original fabric used in the photo book shown in FIG.
A base material roll that has been processed into a roll by printing a plurality of transparent base materials on which photographic images of frame cuts are printed in the longitudinal direction is prepared. The base material roll is installed in the raw fabric manufacturing apparatus, and a plurality of connected transparent base materials 31 fed out from the base material roll R1 are applied to the guide roll 41 and then driven up and down by a servo motor (not shown). It is pulled by the roll 42 and the rotatable nip roll 43, and is then hung on the step roll 44 and then on the guide rolls 45 and 46. The level difference roll 44 has a function of keeping the feeding resistance light and constant with respect to the drawing of the transparent base material 31 from the downstream side. The base material supply roll 42 has a function of adjusting the amount of advancement of the transparent base material 31 to be decreased when the step roll 44 is lowered to the lower limit position, and the amount of advancement of the transparent base material 31 is increased when it is raised to the upper limit position. Have. In FIG. 7, between the guide roll 46 and the roll 48, the upper side of the transparent substrate 31 is a photographic image printing surface.

Next, the transparent substrate 31 is hung on the guide roll 49 and then on the collar portion 51 of the former 50. Here, the transparent base material 31 is valley-folded (center-folded) so that the printing surface is inward at the center in the short direction. Here, the core base material 32 fed out from the core base material roll R <b> 2 passes through the inside of the guide 52 and is fed out into the valley-folded inner side of the transparent base material 31. Here, as the core base material 32, a plurality of core base materials which are previously connected and processed into a roll shape are used.
The transparent base material 31 is lowered so as to sandwich the core base material 32 inside, and the photographic image surface of the transparent base material 31 and the surface of the core base material are thermocompression bonded at the heat seal portion 54. Adhesion of the transparent base material 31 and the core base material 32 is a method other than thermocompression bonding, for example, a double-sided laminate in which an adhesive is attached between the transparent base material 31 and the core base material 32, only on one side of the core base material. Examples thereof include a single-sided laminate to which an adhesive is attached, a method using a core base material in which both sides or one side is previously pressure-bonded.
Thus, the raw fabric by the transparent base material 31 including the core base material 32 can be manufactured. The manufactured original fabric is preferably wound up in a roll shape for installation in the next apparatus.

  Next, a description will be given of an apparatus for bending the long original fabric manufactured by the above apparatus into a bellows shape. FIG. 8 is a conceptual diagram of a bellows folding apparatus that can be used in the photo book shown in FIG. As shown in FIG. 8, the original fabric manufactured by the above-described process is fed out from the original fabric roll R3 by a feeding device 62 under servo control. The unrolled original fabric 60 is intermittently fed by a known eye mark sensor 61. Here, instead of the eye mark sensor 61, it may be managed by inputting dimensions. Next, the original fabric 60 is supplied to the ruled line pressing unit 63. The ruled line pressing unit 63 performs ruled line pressing on the surface of the original fabric 60 in synchronization with the feed. Here, a folding pitch in bellows folding is arbitrarily designated. Here, it is preferable to provide a step of appropriately separating the original fabric in order to form one photobook. The original fabric 60 with the ruled line added is supplied to the pressing plate 65 supported by the electric slider 64. The original fabric 60 fed out at a predetermined interval in synchronism with the feeding is subjected to folding with reference to the crease line. The fold-processed original fabric 60 is stored in the storage portion 66 and held so that the folded portion does not return, and is embossed to form a strong crease. Thereafter, as shown in FIG. 6, the photo book can be manufactured by cutting the bag-shaped portion other than the binding portion.
