Description

  The present invention relates to a recorded matter manufacturing paper, a method of manufacturing a recorded matter, and a recorded matter.

In recent years, there is a service that prints image data of a user and binds a photo book (see, for example, Patent Document 1).
Currently, in the service of manufacturing photo books, it is desired to manufacture high quality photo books with better design.
For example, some photobooks are created by overlaying a plurality of double-sided prints on one side and binding the one side as a binding margin. In this way, a lightweight and multi-page photo book can be manufactured. However, when the photo book is spread left and right with this one side as the center, the two spread pages are visually discontinuous at the bound side. As a result, there is a problem that it is difficult to express with an impact on one side of a spread, the layout is limited to one side each, and there is a restriction on the expression.

On the other hand, some photobooks are manufactured by folding a printed material printed on one side and bonding the non-printed back side. The photobook manufactured in this way may not require a wide binding margin, and at this time, the two-page spread can visually give the impression that it is close to one image, and the degree of freedom in layout is increased. Increase.
However, conventionally, when the method as described above is used, there is a problem that an operation of opening a page cannot be smoothly performed in a recorded matter to be manufactured. That is, when a predetermined page of the recorded matter is opened, it is difficult to keep the opened state, and it may be closed unintentionally. Such a problem occurs more remarkably in a recorded matter having a large number of pages (for example, a recorded matter having 10 pages or more).

JP 09-43827 A

  An object of the present invention is to provide a paper for producing a recorded matter that can be suitably used for manufacturing a recorded matter that can favorably hold the state in which the page is opened, and to favorably retain the state in which the page is opened. It is an object of the present invention to provide a method for producing a recorded matter that can produce a recorded matter that can be produced with high productivity, and to provide a recorded matter that can suitably maintain a state in which a page is opened.

Such an object is achieved by the present invention described below.
The recorded matter manufacturing paper of the present invention has a base material and an adhesive layer, and a recorded matter having a plurality of pages is obtained by adhering on the surface on which the adhesive layer is provided in a folded state.

It is preferable that the third regions for even pages are respectively arranged on the side opposite to the side where the first region is present.

In the recorded matter manufacturing paper of the present invention, the adhesive layer is preferably composed of a material containing polyisoprene.
Thereby, higher adhesive strength can be obtained by pressurization while suppressing stickiness of the adhesive layer. Also, even if the recorded material has a relatively large thickness (a large number of pages), the uniformity of the pressure applied to the whole can be increased more easily. Variation can be more effectively suppressed. Moreover, since heating is not required for bonding, it is preferable from the viewpoint of energy saving. In addition, the adhesive layer has a more suitable grip force, can improve the transportability of the recording paper, and more reliably prevent idling of the transport roller of the recorded product manufacturing apparatus. Thus, a desired image can be reliably formed by a target portion. In addition, it is possible to more reliably prevent the occurrence of paper dust derived from the base material in the recorded product manufacturing apparatus, making maintenance of the recorded product manufacturing apparatus easier and more effectively preventing troubles caused by paper dust. Therefore, the productivity of recorded matter can be improved. In addition, since polyisoprene is a highly flexible material, the elasticity of the recording paper is prevented from becoming unnecessarily large, and it can maintain ease of handling, and an adhesive due to bending of the recording paper. Layer cracks and the like can be reliably prevented, and the reliability and durability of recording paper and recorded matter produced using the recording paper can be made excellent. In addition, by including polyisoprene, when manufacturing recorded matter, sufficient adhesive strength can be easily obtained by pressurization, while recording paper is stored in layers, such as when recording paper is stored. In addition, in the state where the roll-shaped recording paper is wound up, unintentional adhesion (blocking) is more reliably prevented. Further, it does not give off a peculiar smell like vinyl acetate or acrylic resin generally used as an adhesive.

In the recorded product manufacturing paper of the present invention, the polyisoprene preferably has a weight average molecular weight of 100,000 to 500,000.

In the recorded matter manufacturing paper of the present invention, the adhesive layer is preferably composed of a material containing a water-soluble resin in addition to the polyisoprene.
Thereby, the adhesiveness by an adhesive bond layer can be made especially excellent, and higher adhesive strength can be obtained in a recorded matter. In addition, since sufficient adhesive strength can be obtained with a lower pressure in the production of recorded matter, it is possible to reduce the size and simplification of the recorded matter production apparatus.
In the paper for producing recorded matter of the present invention, the adhesive layer preferably contains polyvinyl alcohol as the water-soluble resin.
Thereby, the adhesiveness by an adhesive bond layer can further be improved.

In the recorded matter manufacturing paper of the present invention, the content of the polyisoprene in the adhesive layer is X _A [wt%], and the content of the polyvinyl alcohol in the adhesive layer is X _B [wt%]. In this case, it is preferable to satisfy the relationship of 3 ≦ X _A / X _B ≦ 19.
Thereby, the adhesiveness by an adhesive bond layer can be made further excellent.
In the recorded matter manufacturing paper of the present invention, the adhesive layer preferably has a thickness of 1 μm or more and 10 μm or less.
Thereby, the adhesive strength in the finally obtained recorded matter and the durability of the recorded matter can be made particularly excellent.

The method for producing a recorded matter of the present invention includes an image forming step of forming an image on a surface opposite to the surface provided with the adhesive layer of a recording paper having a base material and an adhesive layer;

The width of the first area to be the front cover is W _A [mm], the width of the second area to be the back cover is W _B [mm], and it is a page other than the front cover and the back cover. When the width of the power third region is W _C [mm], the relationship of W _A ≧ W _C and W _B ≧ W _C is satisfied.
Accordingly, it is possible to provide a method for producing a recorded matter that can produce a recorded matter that can suitably hold the opened state with high productivity.

In the method for producing a recorded matter of the present invention, the substrate is roll paper,
It is preferable to further include a cutting step of cutting the recording paper.
Thereby, for example, a plurality of types of recorded matter having different conditions such as the number of pages and the page width can be manufactured with high productivity.
In the recorded matter manufacturing method of the present invention, it is preferable that the cutting step is provided between the creasing step and the pressing step.
In the method for producing a recorded matter of the present invention, it is preferable that the pressurizing pressure in the pressurizing step is 3 kgf / cm ² or more and 30 kgf / cm ² or less.

In FIGS. 2 and 3, the image (printing unit) is omitted.

≪Recorded paper manufacturing paper≫
First, the recorded matter manufacturing paper of the present invention will be described.
The recording material manufacturing paper of the present invention is used for manufacturing a recording material in which a surface opposite to the surface on which the image is provided of a paper having an image is bonded.
As shown in FIG. 1, the recorded matter manufacturing paper S10 includes a base material S1 and an adhesive layer S2.

The base material S1 has a function of holding the adhesive layer S2.
Examples of the substrate S1 include plain paper, coated paper, photographic paper, various paper such as offset printing paper, plastic film, metal foil, cloth, and the like.
Moreover, you may use roll paper as base material S1. When the base material S1 is roll paper, even when a plurality of types of recorded materials S100 having different conditions such as the number of pages and the page width are manufactured by using a recorded material manufacturing apparatus as will be described later, it is insignificant. It is possible to increase the productivity of the recorded matter S100 while more preferably preventing the length of the recorded matter manufacturing sheet S10 from being wasted. That is, the on-demand property at the time of producing a recorded matter is higher.
Although the thickness of base material S1 is not specifically limited, It is preferable that it is 30 micrometers or more, and it is more preferable that it is 50 micrometers or more and 200 micrometers or less. When the thickness of the substrate S1 is a value within the above range, the high quality and durability of the recorded material S100 manufactured using the recorded material manufacturing paper S10 can be made particularly excellent.

The adhesive layer S2 has a function of bonding a surface opposite to the surface on which the image S3 of the base material S1 is provided in the production of the recorded material S100.
The adhesive layer S2 may be anything as long as it has adhesiveness. For example, various adhesives, various pressure-sensitive adhesives, and the like can be used as the constituent material of the adhesive layer S2. The adhesive layer S2 may be a double-sided tape. When the adhesive layer S2 is a double-sided tape, the adhesive layer S2 is a release sheet (when the recorded product manufacturing paper S10 is stored, during image formation, etc. (before the recording product manufacturing paper S10 is bonded)). The surface may be protected with a release sheet).

  In particular, the adhesive layer S2 is preferably composed of a material containing a pressure-sensitive adhesive. Thereby, sufficient adhesive strength can be obtained by pressurization while suppressing stickiness of the adhesive layer S2. Further, even if the recorded material S100 has a relatively large thickness (a plurality of layers to be bonded are stacked), the uniformity of the pressure applied to the whole can be easily increased. Variations in the adhesive strength at the site can be suppressed. Moreover, since heating is not required for bonding, it is preferable from the viewpoint of energy saving. In addition, pressure-sensitive adhesives exhibit sufficient tackiness when a pressure higher than a predetermined level is applied, but at pressures lower than that (pressure during storage, pressure applied during printing, etc.), there is almost no tackiness. Therefore, the adjustment of the joining position and the folding operation of the recorded product manufacturing paper S10 can be suitably performed. Therefore, it is possible to effectively prevent the problem of alignment difficulty. Further, since the adhesive layer S2 made of a material containing a pressure-sensitive adhesive is provided, the adhesive layer S2 has an appropriate gripping force, and the transportability of the recorded product manufacturing paper S10 is improved. Therefore, it is possible to reliably prevent the conveyance roller of the recorded product manufacturing apparatus 1 from spinning freely, and it is possible to reliably form a desired image at a target portion. In addition, it is possible to more reliably prevent the occurrence of paper dust derived from the base material S1 in the recorded matter manufacturing apparatus 1, thereby facilitating maintenance of the recorded matter manufacturing apparatus 1 and effectively generating troubles due to paper dust. Therefore, the productivity of the recorded material S100 can be improved. Further, if the adhesive layer S2 is made of a material containing a pressure-sensitive adhesive, when the recording paper S10 is in a roll shape, the recording paper S10 is wound up (the adhesive layer S2 Even when stored in a state where the surface on the side provided with is in contact with the surface on the opposite side, particularly in a state where the surface is squeezed with a relatively high pressure), the adhesive layer S2 faces the adhesive layer S2. While preventing unintentional adhesion (blocking) from occurring to the substrate S1, it is possible to easily obtain sufficient adhesion strength by pressurization when necessary (at the time of manufacturing the recorded matter S100). be able to. Further, since an appropriate grip force can be obtained in a state where the roll-shaped recording paper S10 is wound up, it is effectively prevented that the winding state of the recording paper S10 is unintentionally loosened. Storage can be suitably performed.

  Polyisoprene is preferable as the pressure sensitive adhesive constituting the adhesive layer S2. Thereby, the effects as described above are more remarkably exhibited. In addition, since polyisoprene is a highly flexible material, the elasticity of the recording material manufacturing paper S10 is prevented from becoming unnecessarily large, and the ease of handling can be maintained, and the recorded material manufacturing can be performed. It is possible to reliably prevent the adhesive layer S2 from cracking due to the bending of the recording paper S10, and the reliability and durability of the recording material manufacturing paper S10 and the recording material S100 of the present invention manufactured using the recording material S10. Can be made particularly excellent. In addition, by including polyisoprene, sufficient adhesive strength can be easily obtained by pressurization during the production of the recorded matter S100, while the recorded matter is produced when the recorded matter producing paper S10 is stored. In the case where the recording paper S10 is stored in a stacked manner or in the state where the roll-shaped recorded product manufacturing paper S10 is wound up, it is more reliably prevented that unintentional adhesion (blocking) occurs. Further, it does not give off a peculiar smell like vinyl acetate or acrylic resin generally used as an adhesive.

Polyisoprene is a compound having a structure in which isoprene (2-methyl-1,3-butadiene) is polymerized.
The weight average molecular weight of polyisoprene contained in the adhesive layer S2 is preferably 100,000 or more and 500,000 or less. As a result, a higher adhesive strength can be obtained in the recorded matter, and a sufficient adhesive strength can be obtained at a lower pressure in the production of the recorded matter S100. Can be achieved. Moreover, the outstanding adhesiveness is acquired only by the pressurization under the room temperature of 40 degrees C or less, without heating. On the other hand, when the weight average molecular weight of the polyisoprene is less than the lower limit, the flexibility of the adhesive layer S2 becomes insufficient, and the adhesive layer is bonded only by pressing at a room temperature of 40 ° C. or less without heating. Can be difficult. On the other hand, when the weight average molecular weight of polyisoprene exceeds the above upper limit, the elasticity of the recording material manufacturing paper S10 increases, and the handling of the recording material manufacturing paper S10 and the recording material S100 decreases, or the recording material manufacturing There is a possibility that the reliability and durability of the sheet S10 and the recorded matter S100 are lowered.

In addition, a weight average molecular weight can be calculated | required by the gel permeation chromatography (GPC) measurement using the Tosoh Co., Ltd. product and HLC-8320GPC, for example. In the present specification, “weight average molecular weight” refers to the value obtained as described above unless otherwise specified.
The content of polyisoprene in the adhesive layer S2 is preferably 75% by mass or more and 95% by mass or less.

  Further, the adhesive layer S2 may include a water-soluble resin. Thereby, the adhesiveness by adhesive bond layer S2 can be made especially excellent. Therefore, a higher adhesive strength can be obtained in the recorded matter S100, and a sufficient adhesive strength can be obtained at a lower pressure in the production of the recorded matter S100. Can be achieved.

As the water-soluble resin contained in the adhesive layer S2, for example, it is preferable to contain polyvinyl alcohol. Thereby, the effect by including water-soluble resin as mentioned above is exhibited more notably.
The average molecular weight of polyvinyl alcohol is preferably 400 or more and 2,000 or less. When the average molecular weight of the polyvinyl alcohol is less than the lower limit value, when the recording material producing paper S10 is stored in a stacked manner or when the rolled recording material producing paper S10 is wound, the adhesive layer S2 and Unintentional adhesion (blocking) is likely to occur between the opposing substrate S1. Moreover, when the average molecular weight of polyvinyl alcohol exceeds the said upper limit, the tendency for the adhesiveness by adhesive bond layer S2 to fall will appear.

  The content of polyvinyl alcohol in the adhesive layer S2 is preferably 5% by mass or more and 25% by mass or less. Thereby, the adhesiveness by adhesive bond layer S2 can be made further excellent. On the other hand, the adhesiveness by adhesive bond layer S2 will appear that the content rate of polyvinyl alcohol is less than the said lower limit. Further, when the content of polyvinyl alcohol exceeds the upper limit value, when the recording material manufacturing paper S10 is stored in an overlapping manner, or when the rolled recording material manufacturing paper S10 is wound up, the adhesive layer S2 and Unintentional adhesion (blocking) is likely to occur between the opposite substrate S1.

When the polyisoprene content in the adhesive layer S2 is X _A [wt%] and the polyvinyl alcohol content in the adhesive layer S2 is X _B [wt%], 3 ≦ X _A / X _B It is preferable that the relationship of ≦ 19 is satisfied. By satisfying such a relationship, the adhesiveness by the adhesive layer S2 can be further improved. On the other hand, when X _A / X _B is less than the lower limit, the adhesive is used when the recording material manufacturing paper S10 is stored in an overlapping manner or when the rolled recording material manufacturing paper S10 is wound up. Unintentional adhesion (blocking) is likely to occur between the layer S2 and the substrate S1 facing the layer S2. Further, when the X A _/ X _B exceeds the upper limit, the adhesion by the adhesive layer S2 tendency appears to decrease.
The adhesive layer S2 may include components other than polyisoprene. Examples of such components include surfactants, preservatives and fungicides, pH adjusters, antioxidants, metal trapping agents, moisturizers, dispersants, dispersion aids, fillers, adhesion promoters, and agglomerates. Examples thereof include an inhibitor, a photocurable resin, a thermosetting resin, a polymerization initiator, and a polymerization inhibitor.

The thickness of the adhesive layer S2 is not particularly limited, but is preferably 1 μm or more and 10 μm or less. Thereby, the adhesive strength in the finally obtained recorded matter S100 and the durability of the recorded matter S100 can be made particularly excellent.
The adhesive layer S2 may be provided on the entire surface of the base material S1, or may be provided on only a part thereof. For example, the adhesive layer S2 may be applied on the substrate S1 in the form of a line, a dot (dot), or the like. Further, in the production of the recorded matter S100, the adhesive layer S2 may be provided only on a portion corresponding to one of the surfaces to be joined of the recording paper S10.

  In particular, when the adhesive layer S2 is provided on the entire surface of the base material S1, a gap is formed in a portion that is not bonded as compared to the case where the adhesive layer S2 is provided only on the end portion of the base material S1. Can be more reliably prevented, the operability when turning the page can be made particularly excellent, and the sense of luxury of the finally obtained recorded matter S100 is also made particularly excellent. be able to.

The recorded product manufacturing sheet S10 includes an area (first area) SA to be a front cover, an area (second area) SB to be a back cover, and a plurality of pages other than the front cover and the back cover. Area (third area) SC (see FIGS. 2 and 3). The region that becomes the front cover the width of the (first area) SA _W A [mm], a region to be a back cover the width of the (second region) SB _W B [mm], the front cover, back when the width of the region that becomes the pages other than the front cover (third area) SC was _W C [mm], satisfy the relation: _{W a} ≧ _{W C} and _{W B} ≧ _{W C.} By satisfying such a relationship, when the recorded material S100 is manufactured using the recorded material manufacturing paper S10, the page is closed when a predetermined page of the recorded material S100 is opened in the recorded material S100. Generation of a directional force can be effectively prevented, the open state can be suitably maintained, and unintentional closing can be effectively prevented.
In the present invention, W _A and W _C preferably satisfy the relationship of W _A ≧ W _C. Thereby, the effects as described above are more remarkably exhibited.
In the present invention, it is preferable that W _B and W _C satisfy the relationship of W _B ≧ W _C. Thereby, the effects as described above are more remarkably exhibited.

In the configuration shown in FIG. 2, an area (first area) SA to be a front cover and an area (second area) SB to be a back cover are provided adjacent to each other.
In addition to the first area SA, the second area SB, and the third area SC, the configuration shown in FIG. 3 further includes an area (fourth area) SD to be a spine. .
In particular, in the configuration shown in FIG. 3, the area (fourth area) SD to be a back cover is an area (first area) SA to be a cover and an area (second area) to be a back cover. ) It is provided between SB.
In the configuration shown in FIG. 2 and FIG. 3, the side opposite to the side where the second region SB exists among the sides configuring the outer periphery of the first region SA and the outer periphery of the second region SB are configured. The third areas SC for even pages are respectively arranged on the side opposite to the side where the first area SA is present.

≪Adhesive-containing composition≫
Next, an adhesive-containing composition that can be suitably used for the production of the recorded matter production paper S10 (formation of the adhesive layer S2) will be described.
Hereinafter, the case where the adhesive-containing composition includes a pressure-sensitive adhesive as an adhesive component will be mainly described.
The adhesive-containing composition is usually a liquid.
The pressure-sensitive adhesive may be included in any form in the adhesive-containing composition, but is preferably included as a dispersoid that is dispersed in a dispersion medium. Thereby, drying efficiency improves and the effect that an adhesive bond layer pattern can be formed accurately is acquired.

  When the pressure-sensitive adhesive is contained as a dispersoid in the adhesive-containing composition, the average particle size of the pressure-sensitive adhesive particles is preferably 10 nm to 1 μm, and preferably 100 nm to 1 μm. Is more preferable. When the average particle diameter of the pressure-sensitive adhesive particles is less than the lower limit value, the adhesive layer S2 formed of the adhesive composition has a large stickiness, and the roll-formed recording sheet S10 is wound up. In the state, there is a possibility that unintentional adhesion (blocking) occurs. Moreover, when the average particle diameter of the pressure-sensitive adhesive particles exceeds the upper limit, good adhesion may not be obtained.

  The average particle diameter is measured by, for example, a particle size analyzer using a dynamic light scattering method. Pure water is added to the emulsion to dilute it 100 times, and it can be expressed as a 50% by mass number average particle diameter measured using Nitraso UPA-EX150 manufactured by Nikkiso Co., Ltd. In the present specification, the “average particle size” refers to the value obtained as described above unless otherwise specified.

  The content of the pressure sensitive adhesive in the adhesive-containing composition is preferably 2.5% by mass or more and 25% by mass or less. When the content of the pressure-sensitive adhesive is less than the lower limit, production efficiency for securing the thickness of the adhesive layer S2 may be reduced when the adhesive layer S2 is formed from the adhesive composition. There is. Further, when the content of the pressure-sensitive adhesive exceeds the upper limit, the viscosity of the adhesive-containing composition is increased, for example, the handling of the adhesive-containing composition at the time of manufacturing the recording material manufacturing paper S10. There is a possibility that easiness (for example, ejection stability by an ink jet method, etc.) may decrease.

The adhesive-containing composition only needs to include at least an adhesive, but may further include other components.
For example, a solvent that dissolves the adhesive and a dispersion medium that disperses the adhesive may be included. As the solvent and the dispersion medium, those containing water and a water-soluble organic solvent having a boiling point corresponding to 1 atm of 70 ° C. or more and 250 ° C. or less can cause the resin to exist stably in the adhesive composition, Further, when the adhesive-containing composition is ejected by an ink jet method, the adhesive-containing composition can have excellent ejection stability, and the adhesive composition has excellent volatility. Can be formed with high accuracy, which is preferable.

  The water-soluble organic solvent is preferably an aqueous liquid containing at least one selected from lactams, carboxylic acid esters, alkylene glycol ethers, and alcohols. Among these, an aqueous liquid containing 2-pyrrolidones (γ-butyrolactams), lactic acid esters, alkylene glycol ethers, and alcohols is more preferable.

Examples of the water-soluble organic solvent include, but are not limited to, ethanol (boiling point 78 ° C.), N-methyl-2-pyrrolidone (boiling point 202 ° C.), N-ethyl-2-pyrrolidone (boiling point 212 ° C.), 2 -Pyrrolidone (bp 245 ° C), dimethyl sulfoxide (bp 189 ° C), methyl lactate (bp 145 ° C), ethyl lactate (bp 155 ° C), isopropyl lactate (bp 168 ° C), butyl lactate (bp 188 ° C), ethylene glycol Monomethyl ether (boiling point 124 ° C.), ethylene glycol dimethyl ether (boiling point 85 ° C.), ethylene glycol monomethyl ether acetate (boiling point 145 ° C.), diethylene glycol monomethyl ether (boiling point 194 ° C.), diethylene glycol dimethyl ether (boiling point 162 ° C.), diethylene glycol ethyl methyl Ether (boiling point 176 ° C), diethylene glycol diethyl ether (boiling point 189 ° C), propylene glycol monomethyl ether (boiling point 120 ° C), propylene glycol dimethyl ether (boiling point 97 ° C), dipropylene glycol monomethyl ether (boiling point 188 ° C), dipropylene glycol dimethyl ether (Boiling point 171 ° C), 1,4-dioxane (boiling point 101 ° C), ethylene glycol (boiling point 197 ° C), diethylene glycol (boiling point 244 ° C), propylene glycol (boiling point 188 ° C), dipropylene glycol (boiling point 232 ° C), 1 , 3-propanediol (bp 212 ° C), 1,4-butanediol (bp 230 ° C), hexylene glycol (bp 198 ° C), 2,3-butanediol (bp 77 ° C), n-butanol Boiling point 118 ° C), 1,2-hexanediol (boiling point 224 ° C), 1,2-pentanediol (boiling point 206 ° C), diethylene glycol monobutyl ether (boiling point 116 ° C), and diethylene glycol monopropyl ether (boiling point 153 ° C). It is done.
The water-soluble organic solvent having a boiling point corresponding to 1 atm of 70 ° C. or more and 250 ° C. or less may be used alone or in combination of two or more.

  In particular, the adhesive-containing composition preferably contains water as a dispersion medium for dispersing the adhesive particles. As a result, the dispersion stability of the adhesive particles in the adhesive-containing composition can be made sufficiently excellent, and the recording material manufacturing paper S10 can be more suitably manufactured. Further, since water has moderate volatility, it is easily removed at the time of manufacturing the recording material manufacturing sheet S10 while preventing the composition change during storage more reliably. This is also advantageous in improving the productivity of the product manufacturing paper S10. Moreover, the load with respect to the environment by using water can be reduced.

Further, in the case where the adhesive is contained as a dispersoid in the adhesive-containing composition, if the adhesive-containing composition contains a water-soluble resin as described above, the dispersion stability of the dispersoid, The storage stability of the adhesive-containing composition can be made particularly excellent. As a result, for example, when the adhesive-containing composition is discharged by an inkjet method, the discharge stability of the adhesive-containing composition can be made particularly excellent.
When the adhesive-containing composition contains a water-soluble resin, the water-soluble resin is preferably contained in a dissolved state in the adhesive-containing composition. Thereby, the effects as described above are more reliably exhibited.

  In addition, since the adhesive-containing composition contains polyvinyl alcohol together with polyisoprene due to the content ratio as described above, the above-described effects can be obtained in the paper for producing recorded matter S10, and the adhesive-containing composition. In the case where the polyisoprene is contained as a dispersoid, the dispersion stability of the dispersoid, the storage stability of the adhesive-containing composition, etc. can be further improved, for example, an adhesive containing In the case where the composition is discharged by an ink jet method, the discharge stability of the adhesive-containing composition can be further improved.

  Further, the adhesive-containing composition may include a surfactant. Thereby, the adhesiveness by an adhesive-containing composition can be made especially excellent. Further, when the adhesive-containing composition contains a water-soluble resin, when the adhesive is contained as a dispersoid in the adhesive-containing composition, the dispersion stability of the dispersoid, the adhesive-containing composition The storage stability and the like can be made particularly excellent. As a result, for example, when the adhesive-containing composition is discharged by an inkjet method, the discharge stability of the adhesive-containing composition can be made particularly excellent. In addition, it is possible to more effectively prevent unintentional variations in the film thickness of the formed adhesive layer S2 during the production of the recorded matter production paper S10.

A particularly preferable surfactant is a combination including both a silicone-based surfactant and an acetylene glycol-based surfactant having an HLB value of 17 or less.
Moreover, it is preferable that the surface tension of the adhesive composition is in the range of 23.0 mN / m or more and 40.0 mN / m or less by combining the water-soluble organic solvent and the surfactant described above, more preferably 25. The range is from 0.0 mN / m to 35.0 mN / m. When the surface tension of the adhesive composition is within the above range, the ejection stability in the inkjet head is excellent.

Thereby, patterning of the adhesive layer can be realized very simply, and a small amount of various kinds of recorded matter can be manufactured efficiently, inexpensively and in a short time.

≪Recordings≫
Next, the recorded matter of the present invention will be described.
The recorded matter of the present invention is manufactured using the recorded matter-producing paper of the present invention as described above. Thereby, the recorded matter which can hold | maintain the state which opened the page suitably can be provided.
In the present invention, the recorded material may be any material in which the surface opposite to the surface on which the image is provided is bonded to the sheet on which the image is formed. , Calendars, greeting cards, catalogs, books, paperback books, papers, etc.

Among these, the recorded material is preferably a photo book.
Photobooks are for viewing purposes, and require expression that has an impact on one side of the page, but in the past, such expression has been difficult. Also, because the photo book is for viewing, when you open a given page, if you can't hold it open properly and close it unintentionally, watch it carefully. Will be hindered. Among various recorded materials, when a predetermined page is opened, it is difficult to keep the opened state, and it may be closed unintentionally. On the other hand, in the present invention, it is possible to express with a double-faced impact, and to reliably prevent the occurrence of the above problems. That is, when applied to a photobook as a recorded matter, the effects of the present invention are more remarkably exhibited.

  As shown in FIG. 4, in the recorded material S100 of the present embodiment, the recorded material manufacturing paper S10 having the base material S1 provided with the printing unit S3 and the adhesive layer S2 includes the above-described regions (first). Area SA, second area SB, third area SC, fourth area SD) is bent at the boundary with the adjacent area, and the adhesive layer S2 of the recording material production sheet S10 is formed. It has a structure in which the parts are joined together.

  In the configuration shown in FIG. 4, for the sake of convenience, the number of pages (including the front cover and back cover) of the recorded material S100 is shown as six, but the present invention is not limited to this. The number of pages (including front cover and back cover) of the recorded material S100 is preferably 6 pages or more, and more preferably 8 pages or more and 300 pages or less. As described above, when the number of pages of the recorded material is relatively large, conventionally, when a predetermined page of the recorded material is opened, it is difficult to maintain the opened state, and it is unwilling. In the present invention, even when the number of pages of the recorded matter is relatively large as described above, the occurrence of the above problem is surely prevented. be able to. That is, the effect of the present invention is more remarkably exhibited when the number of recorded pages is relatively large as described above. Further, when the number of pages of the recorded material is a value within the above range, the sense of quality and durability of the recorded material can be made particularly excellent.

  The thickness of the recorded material S100 is not particularly limited, but is preferably 3 mm or more, and more preferably 5 mm or more and 50 mm or less. As described above, when the thickness of the recorded matter is relatively large, conventionally, when a predetermined page of the recorded matter is opened, it is difficult to keep the opened state, and the recorded matter is closed unintentionally. However, in the present invention, the occurrence of the above-described problem can be reliably prevented even when the thickness of the recorded material is relatively large as described above. it can. That is, the effect of the present invention is more remarkable when the thickness of the recorded material is relatively large as described above. Further, when the thickness of the recorded matter is within the above range, the sense of quality and durability of the recorded matter can be made particularly excellent.

≪Recorded material manufacturing method≫
Next, the manufacturing method of the recorded matter of the present invention will be described.
As shown in FIG. 5, in the method of manufacturing the recorded matter S100 of the present embodiment, a recording sheet S10 having an adhesive layer S2 on a substrate S1 is prepared (1a), and the surface on which the adhesive layer S2 is provided. An image forming step (1b) for forming an image (printing unit) S3 on the opposite side of the surface, and a creasing step for placing a streak S4 in a recording paper (paper for manufacturing recorded matter) S10 on which the image S3 is formed ( 1c), a cutting step (1d) for cutting the recording paper S10 to a predetermined length, and the surface on which the image S3 is formed by pressurizing the recording paper S10 in a folded state at the portion where the streak S4 is provided. And a pressing step (1e) for bonding the opposite surfaces (the surfaces provided with the adhesive layer S2) to each other. In the creasing step (1c), for each of the above-described regions (the first region SA, the second region SB, the third region SC, and the fourth region SD), Add muscle S4. Thereby, it is possible to provide a method of manufacturing the recorded matter S100 that can manufacture the recorded matter S100 that can suitably hold the opened state with high productivity.

By the way, there are kinds of bookbinding such as flat binding and perfect binding. Flat stitching is a bookbinding method in which a plurality of sheets are sewn together with threads, wires, or the like. Wireless binding is a bookbinding method in which a spine portion that becomes a book is hardened with an adhesive.
In these bookbinding methods, the back portion is hardened. Therefore, when a photo book is created in which a single photo can be seen on a spread page, the left and right pages cannot be opened completely, and there is a problem that it is difficult to see the joint between the left and right pages. Further, since there may be a shift between the left and right pages, such a bookbinding method is difficult to employ in a photo book or the like.
On the other hand, in the present invention, it is possible to provide a recorded material in which the left and right pages are completely opened even after bookbinding, and the left and right pages are easily viewed.
In particular, according to the present embodiment, it is possible to provide a recorded matter that is excellent in aesthetics by preventing a shift in the printing position and the position of the scoring.

≪Recorded product manufacturing equipment≫
Hereinafter, a recorded product manufacturing apparatus that can be used in the recorded product manufacturing method of the present invention will be described.
The recorded product manufacturing apparatus 1 used in the present embodiment includes a paper feed unit 10, a delivery unit 20, a conveyance unit (conveyance unit) 30, a nipping unit (nipping unit) 40, a discharge unit 50, and a printing unit 60. The creaser unit 70 includes a creaser unit 70, a cutting unit 80, a controller 90, a detector group 95, and a pressurizing unit 97.

The controller 90 includes an interface 91 for connecting to the computer 2. Thereby, two-way communication with the computer 2 can be performed. Then, a print command is transmitted to the recorded product manufacturing apparatus 1 via a printer driver installed in the computer 2.
The controller 90 further includes a CPU (Central Processing Unit) 92 that is an arithmetic device, a memory 93 that is a storage device, and a unit control circuit 94 that controls each unit. Thereby, the print command sent from the recorded product manufacturing apparatus 1 is interpreted, and each unit to be described later is controlled.

  The paper feed unit 10 includes a paper feed roll shaft 11 and a paper feed roll motor 12. A roll-shaped recording sheet S <b> 10 is set on the sheet feeding roll shaft 11. Further, an output shaft of a paper feed roll motor 12 is connected to the paper feed roll shaft 11 through a gear (not shown) so that power can be transmitted. Thereby, the controller 90 can control the rotation of the paper feed roll shaft 11 by controlling the paper feed roll motor 12. The rotation of the paper feed roll shaft 11 is controlled by the controller 90 so that the recording paper S10 is slightly loosened with a feed roller 21a described later. Then, no tension is generated between the paper feed roll shaft 11 and the feed roller 21a.

  The delivery unit 20 includes a delivery roller 21a, a driven roller 21b, and a delivery motor 22. The delivery roller 21a and the driven roller 21b sandwich the recording paper S10. An output shaft of the delivery motor 22 is connected to the shaft of the delivery roller 21a through a gear (not shown) so that power can be transmitted. Thereby, when the controller 90 controls the sending motor 22, the rotation of the sending roller 21a can be controlled. The driven roller 21b is driven to rotate by the frictional force of the feed roller 21a and the recording paper S10.

The delivery roller 21a is controlled by the controller 90 so as to appropriately send out the recording paper S10 drawn from the paper feed roll shaft 11 to a later-described transport roller 31a.
The transport unit 30 includes a transport roller 31a, a driven roller 31b, and a transport motor 32. The conveyance roller 31a and the driven roller 31b sandwich the recording paper S10. An output shaft of the transport motor 32 is connected to the shaft of the transport roller 31a through a gear (not shown) so that power can be transmitted. Thereby, the controller 90 can control the rotation of the conveyance roller 31 a by controlling the conveyance motor 32. The driven roller 31b is driven to rotate by the frictional force of the transport roller 31a and the recording paper S10.

  The transport roller 31a transports the recording paper S10 fed from the feed roller 21a by the controller 90 to below the print head 64. As will be described later, printing by the print head 64 is performed by alternately moving the carriage 61 in the paper width direction and transporting the recording paper S10. The transport roller 31a is responsible for transporting the recording paper S10.

  The clamping unit 40 includes a lower clamping roller 41a, an upper clamping roller 41b, a lower clamping motor 42a, and an upper clamping motor 42b. An output shaft of the lower clamping motor 42a is connected to the shaft of the lower clamping roller 41a via a gear (not shown) so that power can be transmitted. The output shaft of the upper clamping motor 42b is connected to the shaft of the upper clamping roller 41b via a gear (not shown) so that power can be transmitted.

As a result, the controller 90 controls the lower clamping motor 42a and the upper clamping motor 42b, whereby the conveyance of the recording paper S10 by the lower clamping roller 41a and the upper clamping roller 41b can be controlled. That is, it is possible to limit the conveyance of the recording paper S10 and the movement of the recording paper S10 by the control.
Here, the movement of the recording sheet S10 is limited by the power of the two clamping motors 42a and 42b. However, only one clamping motor may be used, and the other clamping roller may be a driven roller.

The discharge unit 50 includes an upstream discharge roller 51a, a driven roller 51b, and an upstream discharge motor 52. The discharge unit 50 further includes a downstream discharge roller 55a, a driven roller 55b, and a downstream discharge motor 56.
An output shaft of the upstream discharge motor 52 is connected to the shaft of the upstream discharge roller 51a through a gear (not shown) so that power can be transmitted. The output shaft of the downstream discharge motor 56 is connected to the shaft of the downstream discharge roller 55a via a gear (not shown) so that power can be transmitted. The driven roller 51b is driven to rotate by the frictional force of the upstream discharge roller 51a and the recording paper S10. The driven roller 55b is driven to rotate by the frictional force of the downstream discharge roller 55a and the recording paper S10.
As a result, the recording paper (recorded product manufacturing paper) S10 that has undergone image formation and creasing is conveyed to the paper discharge side, and the recording paper S10 cut by the cutting unit 80 described later is discharged in a folded state. The paper is discharged to the tray 53.

The printing unit 60 forms an image by an inkjet method, and the image forming process is performed in this unit.
By adopting the ink jet method, the range of paper size to be applied can be made wider, for example, long paper (roll paper, etc.) can be suitably used. An image having no image can be suitably formed, and in the finally obtained recorded matter, the dynamic feeling and high-quality feeling of the image can be made particularly excellent. Further, a relatively small apparatus can be used as an image forming apparatus. Furthermore, since it can be suitably applied to various types of recording media (base materials) such as super gloss, semi-gloss, and matte tone, it can also be applied to fields called so-called fine art, which is impossible with offset printing and laser printers. It is also possible to produce recorded materials with various textures that can be used.

The image formed in this step may be, for example, data recorded on a recording medium such as an SD card, USB memory, or DVD brought in by a user (customer), or may be received through an Internet line or the like. It may be based on the data.
The image formation is performed when the paper supplied from the paper feed roll shaft 11 is intermittently transported by the transport roller 31a and the print head 64 ejects ink.

When the image S3 is formed on the recording paper S10, the lower clamping roller 41a and the upper clamping roller 41b sandwich and transport the recording paper S10 to such an extent that a predetermined tension is generated between the transportation roller 31a.
The conveyance amount of the recording paper S10 is always grasped by the controller 90 based on the rotation amount of the conveyance roller 31a. Further, the controller 90 grasps the position where the creasing should be performed on the recording paper S10. For this reason, the controller 90 causes the creaser unit 70 to perform creasing when the transport amount reaches a predetermined transport amount.

  The printing unit 60 includes a carriage 61, a guide shaft 62, and a print head 64. The guide shaft 62 extends in a direction orthogonal to the transport direction. The guide shaft 62 is supported by the main body case of the recorded product manufacturing apparatus 1, and the carriage 61 is slidably connected so as to be capable of reciprocating along the longitudinal direction of the guide shaft 62. A carriage motor and a belt (not shown) are connected to the carriage 61. Thereby, the carriage 61 is reciprocated in the longitudinal direction of the guide shaft 62 described above.

  The carriage 61 is equipped with a print head (head) 64. The print head 64 is a print head 64 that discharges ink to the base material S1 of the recording paper S10 (the surface opposite to the surface on which the adhesive layer S2 is provided). By doing so, the print head 64 can reciprocate in the direction intersecting the conveyance direction. Therefore, by repeating conveyance of the recording paper S10 and reciprocation of the carriage 61, an image (printing) is printed on the entire surface of the recording paper S10. Part) S3 can be formed.

The creaser unit 70 is a unit in which a creasing process is performed. The creaser unit 70 puts the streak S4 at the boundary with the adjacent region for each of the regions described above (the first region SA, the second region SB, the third region SC, and the fourth region SD). .
In the present embodiment, the creaser unit 70 includes a rotating blade 71 as a convex member that pushes the recording paper S10 linearly, and a blade receiving member 72 as a receiving member that receives the rotating blade 71. As a result, in the creasing process, it is possible to efficiently insert a streak of a desired shape in a short time, and the productivity of the recorded material S100 can be made particularly excellent, and the reliability of the manufactured recorded material S100 can be improved. The quality and luxury can be made particularly excellent.

The rotating blade 71 has a shaft 71a and a blade 71b formed over the circumference thereof. And it can rotate centering on the axis | shaft 71a, and can move to the width direction of recording paper S10. The blade receiving member 72 has an acute cross section in a side view, and the tip of the blade 71b also has an acute cross section corresponding thereto. However, although the tip of the blade 71b has an acute angle, no stress is generated until the recording paper S10 is cut.
Therefore, when the recording paper S10 is sandwiched between the blade 71b and the blade receiving member 72 and the rotary blade 71 moves in the width direction of the recording paper S10, the stress due to the tip of the blade 71b extends in the width direction on the recording paper S10. A streak (fold) is formed.

The rotary blade 71 and the blade receiving member 72 can be made of a metal material such as iron, nickel, aluminum, and anodized. Moreover, you may use what was formed with resin, without using a metal.
Here, although the cross section of the blade receiving member 72 has been described as an acute angle cross section, it may be a horizontally long rectangular cross section or a vertically long rectangular cross section. Further, instead of the rotating blade 71, a blade that does not rotate may be provided, and a streak may be formed simply by sliding in the paper width direction.

Moreover, when performing creasing, the creaser unit 70 may be cut in a broken line shape.
Moreover, the creaser unit 70 can also be exchangeable. As a result, maintenance of the creaser unit 70 is facilitated, and the optimum creaser unit 70 for the recording paper S10 can be used by attaching the blade receiving member 72 with different depth, width, or shape. .
At the timing when creasing is performed by the creaser unit 70, the controller 90 stops and fixes the rotation of the lower nip roller 41a and the upper nip roller 41b. That is, the recording paper S10 is fixed.

  After fixing the recording paper S10 with respect to the transport direction, the controller 90 sends a command to the creaser unit 70 to make a line in the recording paper S10. At this time, as described above, since the recording paper S10 is fixed in the transport direction, the recording paper S10 hardly moves even if the creasing unit 70 makes a line. By doing so, the recording paper S10 does not move in the carrying direction during the creasing operation, so that printing deviation does not occur in printing on the subsequent recording paper S10.

  If a printing misalignment occurs, a misalignment occurs between the printing position and the line entry position. In that case, the position of the crease of the recorded material S100 is shifted, and it is impossible to manufacture the recorded material S100 with high aesthetics. However, according to the recorded material manufacturing apparatus 1, the printing position in the creasing operation in the creaser unit 70 is not possible. Since no deviation occurs, it is possible to provide the recorded material S100 with high aesthetics.

  In the configuration shown in FIG. 7, the recorded matter manufacturing apparatus 1 has a plurality (two sets) of the creaser units 70, and the rotating blade 71 is on the printing surface side (the surface on which the adhesive layer S <b> 2 of the recording paper S <b> 10 is provided). And a creaser unit 70 provided on the surface side where the rotary blade 71 is provided with the adhesive layer S2. With such a configuration, it is possible to suitably form the stripe S4 on both surfaces (the surface on which the adhesive layer is provided and the opposite surface) of the recording paper S10 in the creasing process. Thereby, it is possible to suitably manufacture the recorded matter S100 having a large number of pages by using a small number of recording sheets S10.

The cutting unit 80 is a unit in which a cutting process is performed. By performing the cutting process, for example, a roll-shaped recording sheet S10 can be suitably used for the production of recorded matter, and a plurality of types of recorded matter S100 having different conditions such as the number of pages and page width can be produced with high productivity. can do.
The cutting unit 80 includes a cutter 81 and a cutter receiving member 82. The cutter 81 can be realized, for example, by adopting a sharper tip of the blade 71b of the rotary blade 71 shown in FIG. The cutter receiving member 82 can be realized by adopting a harder material for the blade receiving member 72.
With such a configuration, the recording paper S10 is sandwiched between the cutter 81 and the cutter receiving member 82, and the cutter 81 is moved in the width direction of the recording paper S10, whereby the recording paper S10 is cut at a predetermined position. be able to.

  In the present embodiment, the cutting unit 80 is provided on the downstream side of the creaser unit (leather insertion portion) 70 and on the upstream side of the pressurizing means 97. That is, there is a cutting step between the creasing step and the pressurizing step, and the cutting unit 80 before the recording paper S10 provided with the streaks S4 by the creaser unit 70 is conveyed to the pressurizing means. It is configured to be cut.

  Further, as part of the cutting unit 80, a dot impact head 84 and a platen 85 can be provided. The dot impact head 84 prints printing information and a marker indicating the position to be cut by the cutter 81 on the back surface of the recording paper S10 (the surface opposite to the surface on which the image S3 is formed). The marker is read by an optical sensor 95a described later, thereby making it possible to recognize an accurate cutting position.

The recorded product manufacturing apparatus 1 includes an optical sensor 95 a as one of the detector groups 95. The optical sensor 95a is provided between the upstream discharge roller 51a and the downstream discharge roller 55a in the transport direction. The optical sensor 95a is provided on the back side of the recording paper S10 so as to read the marker formed on the recording paper S10 as described above.
Thus, by providing the optical sensor 95a, the controller 90 can accurately recognize the cutting position (cutting position) of the recording paper S10. Then, by appropriately controlling the cutter 81, the recording paper S10 can be cut at an accurate position.
The recording sheet S10 that has been cut is ejected to the sheet ejection tray 53 in a state where the recording sheet S10 is bent at the streak S4 (the surface opposite to the surface on which the printing unit S3 of the recording sheet S10 is formed). (Stacked) and subjected to pressurization by the pressurizing means 97 (pressurization step). As a result, the surfaces on which the adhesive layer S2 is provided are in close contact with each other, and a recorded material S100 is obtained.

The pressurizing unit 97 may be any unit that presses at least a part of the folded recording sheet S10, but preferably presses the entire surface of the folded recording sheet S10. Thereby, the uniformity of the bonding strength at each part can be made higher, and the reliability of the recorded matter S100 can be made particularly excellent.
Pressurizing pressure by pressurizing means 97 is preferably at 3 kgf / cm ² or more 30 kgf / cm ² or less, more preferably 7 kgf / cm ² or more 13 kgf / cm ² or less. As a result, it is possible to more reliably manufacture the recorded matter S100 having a higher adhesive strength with higher productivity while preventing an increase in the size of the recorded matter manufacturing apparatus 1. On the other hand, if the pressure is less than the lower limit, it may be difficult to obtain sufficient adhesive strength depending on the pattern, thickness, and the like of the adhesive layer S2. If the pressure exceeds the upper limit, there is a possibility of color transfer to another page depending on the composition of the ink used for image formation.
In the above description, each process has been described in order, but in actuality, these processes are executed in parallel.

As mentioned above, although this invention was demonstrated based on suitable embodiment, this invention is not limited to these.
For example, in the above-described embodiment, the cutting process has been described. However, the cutting process may not be performed.
Moreover, in this invention, in addition to the process mentioned above, you may have another process (a pre-process, an intermediate process, a post process).

Moreover, the order of each process is not limited to the above-mentioned thing. For example, in the above-described embodiment, the cutting process is described as being performed between the creasing process and the pressurizing process. However, the cutting process is performed, for example, between the image forming process and the creasing process. There may be.
Further, in the above-described embodiment, the pressurizing unit that constitutes the recorded matter manufacturing apparatus performs the pressurizing step, and thereby, the recorded matter is obtained. A process (temporary bonding) for obtaining a bonding force to prevent misalignment may be performed, and then a final bonding process (main bonding) may be performed using another apparatus. .

Further, the pressurizing means is not limited to the one shown in the figure, and may be, for example, a roll-shaped one (pressing roller).
In the above-described embodiment, each process is described as being performed in a single apparatus. However, at least one of the above-described processes may be performed by another apparatus, or without using an apparatus. You may do it by work.
In the above-described embodiment, the case where the recorded matter is manufactured using one recording sheet has been described. However, in the manufacture of the recorded matter, a plurality of recording sheets may be used.

In the above-described embodiment, the case where the creasing unit (creaser unit) is provided with the rotating blade is representatively described, but the means for creasing is not limited thereto. For example, one that does not have a rotation mechanism, more specifically, one that includes a long plate member that is relatively movable in the substantially normal direction of the recording paper, or one that is relatively in the width direction of the recording paper. The thing provided with the movable dot impact head etc. may be sufficient.
In addition to the mechanical creasing operation as described above, the scoring may be performed on the recording paper by irradiating a laser to form many small holes in the recording paper.

  In the above-described embodiment, the case where a recording sheet on which an adhesive layer is provided in advance is prepared and a recorded matter is manufactured using the recording sheet has been described as a representative example. However, for example, recording without an adhesive layer is described. A recording sheet having an adhesive layer may be manufactured by preparing a medium (base material) and applying an adhesive-containing composition to the medium at the time of manufacturing the recorded material. Thereby, for example, unintentional adhesion (blocking) between the adhesive layer in the recorded product manufacturing apparatus and the base material facing the adhesive layer can be more reliably prevented. Moreover, according to the form (for example, a magnitude | size, the number of pages, etc.) of the recorded matter to be manufactured, the application amount and application pattern of the adhesive-containing composition can be adjusted, and the usage-amount of the adhesive-containing composition can be adjusted. It leads to suppression and is also preferable from the viewpoint of resource saving.

  In the above-described embodiment, the side of the side that forms the outer periphery of the first region, the side opposite to the side where the second region exists, and the side of the side that forms the outer periphery of the second region. The case where the third area for the even number of pages is arranged on the side opposite to the side where the one area exists is representatively described. Out of the sides on the opposite side to the side where the second region is present, and on the side opposite to the side where the first region is present among the sides constituting the outer periphery of the second region, Three regions may be arranged.

First, roll paper (manufactured by Seiko Epson Corporation, super fine paper roll type, 210 mm × 20 m) was prepared as a recording medium (base material).

Next, an adhesive-containing composition was applied to the entire one surface of the recording medium by an ink jet method in a state where the driving waveform of the piezoelectric element was optimized. The amount of the adhesive-containing composition applied to the recording medium per unit area was 30 g / m ² .
Thereafter, an adhesive layer was formed by applying warm air of 70 ° C. for 1 minute. The thickness (dry film thickness) of the formed adhesive layer was 3 μm.

[3] Manufacture of recorded matter The above-described operations are performed using the recording paper obtained as described above and the recorded matter manufacturing apparatus as shown in FIGS. And the recorded matter was manufactured by the method which has a cutting process and a pressurization process.
In the image forming process, an image was formed so that one photo (one image) appeared on two spread pages.
In the scoring step, a streak was made at the boundary between adjacent regions (first region, second region, third region, fourth region).

In the cutting process, the recording paper (paper for manufacturing recorded material) provided with images and streaks was cut so that the number of pages (including the front cover and back cover) of the finally obtained recorded material was 200 pages. The recorded product manufacturing paper obtained through the cutting process has a third area for 96 pages on the side opposite to the side where the second area exists among the sides constituting the outer periphery of the first area. The third area for 98 pages is arranged on the side opposite to the side where the first area exists among the sides constituting the outer periphery of the second area. .
In the pressurizing step, a recorded matter was produced by pressing at a predetermined pressure for 3 minutes at room temperature.
