Abstract

PURPOSE:To stably produce a pressplate with a photosensitive resin uniformly laminated even if a coarse mesh fabric is used by a method wherein while a mesh fabric is continuously fed under a fixed tension applied by a tenter, a photosensitive resin is applied to at least one surface of the fabric by fixed- type bucket coaters and dried under heat. CONSTITUTION:A mesh fabric 1 is produced using a core-sheath composite filament 2 in which a component as a sheath 2a has a melting point lower than that of a core 2b. In the mesh fabric 1, the sheath component melted after weaving ensures the secure adhesion of warps and woofs with core yarns in close contact with each other at the intersections, and the surfaces of the warps and woofs are integrally covered with the sheath component in the whole fabric. This fabric is continuously fed under a fixed tension applied by a tenter. A photosensitive resin is applied to at least one surface of the fabric 1 by fixed-type bucket coaters 12, 13 and dried under heat by a dry heating device 11. As a result, a pressplate with the photosensitive resin layer uniformly laminated can be stably produced with a good workability even if a coarse mesh fabric is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a printing plate using a mesh fabric used for T-shirts, other Japanese clothes, Western clothes, etc., and particularly to forming a uniform photosensitive resin layer on a coarse mesh fabric. And a method for producing a printing plate with good workability.

[0002]

2. Description of the Related Art Conventionally, in screen printing plate making, a mesh fabric such as silk, nylon or polyester is laid on a screen form to form a screen plate, and a photosensitive emulsion is laminated on the screen plate to a predetermined thickness. A photosensitive plate is made by coating (direct method) or by sticking a photosensitive film (direct method), and a positive plate is pressed against this photosensitive plate, and the plate is exposed to produce a printing plate. Or press a positive film against a commercially available photosensitive film,
It was manufactured by transferring the image obtained by exposing to the screen plate surface fixed to the screen form (indirect method).

Such a screen printing plate is usually manufactured by the following method. For example, in the method for producing a screen printing plate by the direct method, a screen plate produced by stretching a screen mesh with a printing mesh fabric is fixed in a state of standing at an inclination angle of 80 to 90 degrees, and the mesh is fixed. Photosensitive resin liquid (photosensitive emulsion) on the surface of fabric
Apply the photosensitive resin to the mesh fabric by applying the photosensitive resin solution to the mesh fabric screen surface by touching the tip portion of the bucket containing the To produce a photosensitive plate.

Further, in the method for producing a screen printing plate by the direct method, the mesh fabric is laid on the screen form, the formed screen plate is thoroughly washed, and the photosensitive film is preliminarily formed on the base film on the lower side thereof. The photosensitive film formed with is cut into the same size as the printing mesh fabric, and the photosensitive film is placed on a smooth table with the photosensitive film on top, and water is sprayed from above the mesh fabric to make it soft. A light sensitive plate was manufactured by lightly pressing with a squeegee and laminating while removing excess water.

The photosensitive plate manufactured by such a manufacturing method is used immediately before being exposed to form an image, or by being purchased in another place in advance. When a woven fabric such as silk, nylon or polyester is used as the mesh fabric for printing such a photosensitive plate, when the woven fabric is stretched on the screen plate,
Stretching, the opening intervals of the mesh of the screen become non-uniform, and applying a mesh fabric to which a photosensitizer and a photosensitive film have been applied to the screen plate is
The photosensitizer layer was not uniform, or the photosensitive film was broken, which was impossible. Therefore, only after pasting these printing mesh fabrics to the screen formwork,
The photosensitizer layer or the photosensitive film could not be laminated.

Further, there is a screen printing screen mesh in which a photosensitizing agent layer or a photosensitive film layer is laminated on an electroforming screen mesh which is not attached to a mold (Japanese Patent Application No. 1-47615). Such a screen printing plate using an electroformed screen mesh is difficult to manufacture at low cost because the electroformed screen mesh itself is expensive, and furthermore, the electroformed screen mesh is still under development. Yes, screen printing meshes have been discontinued.

[0007]

On the other hand, Japanese Patent Laid-Open No. 4-13
No. 6232 discloses a mesh fabric produced by using a core-sheath composite filament in which a component having a lower melting point than a core is used for a sheath as a mesh fabric for a screen, and a warp yarn is obtained by melting a sheath component after weaving. A woven fabric is disclosed in which wefts are fixed to each other in a state in which core yarns are in close contact with each other at intersections, and the surfaces of the warp yarns and the weft yarns are integrally covered with a sheath component over the entire woven fabric. However, this woven fabric is easy to handle because the mesh is kept in a stable state.
It was not considered possible to laminate a laminate of a photosensitizer layer and a photosensitive film by a conventional method.

For example, it has been proposed to laminate a photosensitizer layer and / or a photosensitive film on a mesh fabric, but it is difficult to laminate the photosensitizer without applying tension to the mesh fabric. Only a non-uniform thickness can be obtained and it cannot be put to practical use. Also, in the method of dipping in a bath sensitizer, when the mesh is 80 mesh or less, the film layer is non-uniform and many pinholes are present. It's hard to make.

Further, it is impossible to press-bond the photosensitive film near the fusing temperature because the sheath component is melted, and the base film of the photosensitive film is corrugated at temperature and has not been put to practical use. In addition, since the price of the photosensitive film is high, it is economically impractical.

It is an object of the present invention to provide a method for producing a printing plate more efficiently and stably than ever before by using a mesh fabric produced using such a core-sheath composite filament. .

[0011]

MEANS TO SOLVE THE PROBLEMS As a result of intensive studies, the present inventor has found that a mesh woven fabric in which the intersections of both warp and weft yarns are heat-fused and fixed to each other has substantially no elasticity, Even if it is attached to the screen form after laminating the photosensitive film layer, it does not substantially expand or contract, so if the photosensitizer layer or the photosensitive film layer is laminated in advance before attaching to the screen form, The present invention has been completed based on the finding that a mesh fabric for simple plate-making printing can be produced that is extremely easy to handle and does not need to be attached to a screen frame depending on the application.

That is, the present inventor, contrary to the conventional method, is a method of coating a photosensitive resin with a bucket coater fixed at a fixed position while transporting a mesh fabric under tension, to obtain 80 mesh. The inventors have found that an industrially uniform resin layer can be formed on the following mesh fabrics with good workability, and have completed the present invention.

According to the present invention, there is provided a mesh fabric produced by using a core-sheath composite filament in which a component having a melting point lower than that of the core is used in the sheath, wherein the warp yarns and the weft yarns are mutually crossed at a crossing point by melting the sheath component after weaving. The core yarn is fixed in close contact with the whole fabric, the surface of the warp yarn and the weft yarn, the woven fabric integrally covering the sheath component, in a state where a constant tension is applied by a tenter, while continuously transferring, It is characterized in that a photosensitive resin is applied to at least one side of the woven fabric by a fixed bucket coater and heated and dried.

Even in the lamination of photosensitive films,
The woven fabric is superposed with a photosensitive film on the surface of the woven fabric while being continuously transferred with a constant tension applied by a tenter, and then the back surface of the woven fabric is exposed to light with a fixed bucket coater. By applying a resin and heating and drying, a stable and uniform printing plate can be manufactured.

The mesh fabric used in the present invention, after weaving, melts the sheath component of the core-sheath composite filament so that the core yarns of the warp and weft adhere to each other at the intersection of the warp and the weft, and the sheath component of the warp and the weft on the surface thereof. Are integrally covered, and the intersection of the warp and the weft is integrated with the warp and the weft, resulting in a mesh fabric with no misalignment and no fluff. Since the product of the present invention in which the layers are laminated is not stretched on the mold, the product can be rolled up, stacked and transferred, and is very easy to handle. In addition, the mesh fabric is not broken during the transfer, the tension of the stretched mesh fabric is not loosened, and further, the simple printing can be applied without being attached to the mold.

In the present invention, even with a mesh fabric having a mesh size of 80 mesh or less, which has not been capable of producing a printing plate with high accuracy, accurate platemaking can be easily performed in the present invention without causing misalignment.

The mesh fabric of the present invention is disclosed in Japanese Patent Laid-Open No.
Although any of the woven fabrics disclosed in JP-A-136232 can be used, a mesh woven fabric of 10 mesh to 180 mesh is particularly preferable.

The mesh fabric used in the present invention comprises a core-sheath composite filament. This filament uses a strong fiber component in the core part of the filament and a low melting point component in the sheath part covering it. After being woven into a mesh shape, the composite fiber is used to heat the low melting point component on the outside to fix the intersection of the warp and weft yarns.

As a core component of the composite filament having a core-sheath structure, it is preferable to use a thermoplastic resin having a high melting point and high strength such as polypropylene, polyester or polyamide, and particularly a polyamide or polyester fiber material. Is preferred. Nylon-66 as the polyamide, phthalic acid as the polyester,
Examples include polyesters produced by a condensation reaction of aromatic dicarboxylic acids such as isophthalic acid and naphthalene dicarboxylic acid, and aliphatic or alicyclic diols such as ethylene glycol mixed in a predetermined amount, and especially polyethylene terephthalate (PET). ) Is used by preference.

Next, as the sheath component of the core-sheath composite filament, low density polyethylene, high density polyethylene, ethylene / vinyl acetate copolymer, ethylene / propylene copolymer, low melting point polyester, nylon-6 and the like can be used. It is preferable to use a thermoplastic resin such as a polyamide resin or a mixture thereof, which has a melting point lower than that of the resin used as the core component by 20 ° C. or higher, preferably 30 ° C. or higher.

Among the low melting point thermoplastic resins used as the sheath component, it is preferable to use a low melting point polyester, particularly aliphatic dicarboxylic acids such as adipic acid and sebacic acid, phthalic acid, isophthalic acid and naphthalene dicarboxylic acid. Aromatic dicarboxylic acids such as acids and / or alicyclic dicarboxylic acids such as hexahydroterephthalic acid, and aliphatic or alicyclic diols such as ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, hexanediol and paraxylene glycol It is preferable to use a copolyester resin or the like produced by a condensation reaction in which a predetermined amount is mixed with oxyacids such as paraxylene benzoic acid, if desired. In particular, terephthalic acid and ethylene glycol, isophthalic acid and 1,
It is particularly preferable to use polyester or the like in which 6-hexanediol is added and copolymerized.

The core component and the sheath component are spun by a conventionally known composite spinning method so as to have a core-sheath structure, and the sheath component is 30 to 80%, preferably 40 to 50% of the total cross-sectional area of the fiber. Is preferably spun so as to occupy

By setting the fiber cross-sectional area of the sheath component to the above-mentioned area ratio, the intersection point of the warp and weft of the mesh fabric can be firmly adhered by fusion of the sheath component by the post-treatment described later, and the mesh fabric is also made. Can be firmly adhered to the photosensitive resin layer or the photosensitive film.

In the present invention, the core-sheath type composite filament as described above may be used as a monofilament or a multifilament. The core component is aggregated, and the sheath component is coated around the core component, and the core component is processed as if it were a monofilament. It is preferable to use a monofilament in order to obtain a product with a good picture quality, but it is a multifilament that has good adhesiveness to the photosensitive resin layer even in view of its surface area. Therefore, in the present invention, it is preferable to use multifilaments in the processing described later.

The core-sheath type composite fiber may have a fineness of 1 denier or more, but 5 to 20 denier, particularly 10 denier.
It is preferably ˜100 denier.

Next, the mesh woven fabric may be woven in the same manner as a normal screen mesh woven fabric. For example, even a mesh woven fabric having a low density of 100 mesh or less, particularly 50 mesh or less, is woven by plain weaving and woven. By applying dry heat at this time, the intersection of the warp and the weft can be bonded to form an accurate mesh.

The weave density of the mesh fabric thus woven is usually 10 to 300 filaments / inch (10 to 30).
0 mesh), preferably 10-100 lines / inch (1
It is about 0 to 100 mesh) (for simple plate making), but the weaving density of these is appropriately selected depending on the pattern line or the like.

As described above, the screen mesh fabric for cutting die of the present invention is applied with dry heat when the woven mesh fabric is wound up at the time of weaving to melt the sheath component of the core-sheath composite filament, and if necessary, It is produced by integrating the fabric while applying pressure and then cooling.

As the heating temperature, a temperature between the melting point of the sheath component and the melting point of the core component of the core-sheath composite filament is used.
It is preferred to use elevated temperatures near the melting point of the core component. When the sheath component is a low melting point polyester, it is usually 120 to 2
It is heated to a temperature of 20 ° C, preferably 170-210 ° C.

The mesh fabric 1 thus obtained
As shown in FIG. 1, is the intersection 1a of the yarns of the mesh fabric.
The sheath component 2a of the core-sheath composite filament 2 which constitutes the
Since it is bonded and integrated by melting, it is possible to obtain eyes without misalignment. Therefore, this mesh fabric has an appearance like a resin molded product, but since the entire fabric structure is uniformly covered with the melt of the sheath component 2a of the core-sheath composite filament 2 constituting it, The special bucket method of the present invention enables continuous and uniform coating of the photosensitive resin layer.

Such a mesh fabric has an appearance like a resin molded product, but the entire fabric structure is uniformly covered with the melt of the sheath component of the core-sheath composite film constituting the fabric structure. Therefore, the resin layer can be firmly bonded in a uniform and practically non-shrinking state, which is very efficient.
A printing plate can be manufactured.

The photosensitive resin layer laminated on the mesh fabric is a known photosensitizer, photosensitive emulsion for screen printing,
It may be formed from any of photosensitive films, for example, polyvinyl alcohol and a slight amount of vinyl acetate emulsion, a photosensitive emulsion obtained by adding a dichromate of a photosensitive base and a small amount of an auxiliary agent, and dried, Alternatively, it can be formed by using a photosensitive film, for example, a plastic film base coated with a photosensitive emulsion mainly containing polyvinyl alcohol and a photosensitive base and dried to form a film.

These photosensitive resin layers may be formed by adhering a photosensitive film on the front surface side of the mesh fabric and applying a photosensitive resin on the rear surface side. , Generally 2 to 500 microns, often 5 to 30 microns thick.

As described above, for example, the method shown in FIG. 2 can be applied to laminate the photosensitive resin on the mesh fabric having the intersections of the warp and weft yarns fixed by heat fusion. That is,
The heat-sealing mesh fabric 1 rolled into a roll is forced from the feeding device 3 through the blind roll 4 that removes wrinkles so that the centering device 5 moves it to the center of the machine body, the S roll 6 is passed through, and the pressing roll is passed. At 7, the pin 8 and the mesh fabric 1 are easily pinned, and the width of the mesh fabric is detected by the width detector 9 so that the pin 8 follows the width of the mesh fabric 1. The pressing brush 10 presses the required places so that the pinned mesh fabric does not come off the pins. Next, the pinned mesh fabric 1 is started up in a tensioned state as it is, and before entering the dry heat device 11, it is brought into contact with the fixed buckets 12 and 13 to be coated with resin. The mesh woven fabric in which the resin layers are laminated is a dry heat drying device 1
1 and dried with a pin removal roll 14
Cooled by the cooling roll 15, driven by the S roll 16,
Bending roll 17 and touch roll 1 for wrinkle removal
It is taken up by the take-up device 19 via 8

The width of the bucket can be changed according to the width of the woven fabric. It is also possible to put the resin in the bucket 12 and scrape the resin protruding to the back side without putting the resin in the bucket 13. It is also possible to put the resin in the bucket 13 and stack the resin thickly on the back surface.

Further, the thickness of the resin layer can be set to a predetermined value by changing the angle θ1 of descending from the start-up, the thickness of the mouthpieces of the buckets 12 and 13 and the angle θ2.

With this apparatus, it is also possible to laminate a photosensitive film on a mesh fabric. For example, with a film feeding device (not shown) provided in the vicinity of the feeding device 3, a photosensitive film obtained by laminating a photosensitive resin on a base film is fed and laminated on the mesh fabric 1,
The film is pressed by the bucket 12, and the photosensitive resin is applied to the back surface of the mesh fabric 1 by the bucket 13 containing the photosensitive resin, and the photosensitive film on the front surface and the photosensitive resin on the back surface are integrated.

According to the method of the present invention as described above, it is possible to easily laminate the photosensitive resin by the bucket method even in the case of the mesh fabric having a high density, which is difficult by the dipping method, and the printing plates are continuously manufactured. it can. Further, the thickness of the resin layer can be easily controlled, and a product in which the photosensitive resin layers having a uniform thickness are laminated can be stably obtained.

The product obtained by laminating the photosensitive resin in this manner can be used as a screen printing plate by sticking it to a screen form. However, since this product has an appropriate hardness and is excellent in shape stability, Depending on the application, such as Western clothing and hand-printing of T-shirts, etc., it may be directly used for screen printing without being stretched on the formwork.

When it is used by being attached to a screen form, the screen form may be made of wood or metal such as aluminum, stainless steel, steel, etc. It is preferable to use a mold made by processing an extruded material of aluminum. In addition, in order to stretch it on the formwork, it is usually used to stretch the screen mesh fabric, for example, an air stretcher stretcher or a large stretcher (motor driven, hydraulic type long stand). Method) or the like may be used. However, the product of the present invention uses a mesh woven fabric in which the intersections of the warp and weft yarns are fixed to the base by heat fusion, and a photosensitive resin layer (or a photosensitive film layer) is formed on the surface thereof.
Since the mesh intervals are not easily deformed and the shape stability is excellent, the screen form can be easily stretched by hand without using a stretcher.

The mesh fabric for simple plate-making / printing of the present invention is not fixed to the screen form frame by using an adhesive. Generally, when a rubber-based adhesive is used, the adhesive is cured until the adhesive is cured. Although it takes about 60 minutes, the product of the present invention can be easily stretched by hand, and can be used for general printing even if it is stuck on a wooden frame with a stapler or the like. Therefore, in the present invention, in a very short time,
It can be fixed to the screen formwork with good workability.

In this way, the product of the present invention is stretched on the screen form, or depending on the application, the image is printed, exposed and developed in the state as it is.
The final printing plate is finished.

Conventionally, a mesh fabric is covered with a cloth, washed with an aqueous solution of a neutral detergent, dried, coated with a photosensitive emulsion and dried, and the coating thickness is adjusted to a predetermined thickness, Although it is subjected to image printing, exposure, and development steps, many of these steps can be omitted in the present invention.
