Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a tool for repairing a pattern paint of a painted object for quickly and easily repairing a locally defective portion of a pattern paint having a design property of the painted object. is there.

[0002]

2. Description of the Related Art In recent years, painted objects having a pattern paint having a design property applied on the surface thereof, for example, architectural wall materials having a multicolor pattern paint applied on the surface thereof have been widely used. In an object, a local defect may occur in the pattern painting. For example, when nailing is performed on a wall of a building using a building wall material on which a pattern painting is applied, a part of the pattern painting is lost. In the case where a locally defective portion occurs in the pattern painting of the painted object, it is necessary to repair (repaint) the defective portion in order to restore or maintain the appearance of the painted object. .

[0003]

However, it is very difficult to repair the pattern painting of the painted object. For example, when a defective portion occurs in a single-color uniform coating, it can be repaired by simply applying the same color paint to the defective portion using a brush or the like. On the other hand, when a defective portion occurs in the pattern painting, especially in the multicolored pattern painting, the defective portion cannot be repaired by such a simple method. In addition,
Since such painted objects, for example, walls of buildings, generally have to go to the site for repair work, the equipment and tools used for the repair need to be lightweight and compact and do not require utilities such as electricity. It is.

[0004] Here, in the case where the pattern painting is, for example, a dot-like (dot-like) pattern, conventionally, a paint is adhered to a brush and the brush is appropriately flicked with a finger to form a dot-like portion on a defective portion. A repair method such as forming a pattern, a repair method such as spraying paint to a defective part with a spray using a sprayer to form a dot pattern, and further spraying a paint to a defective part with an aerosol A repair technique such as forming a dot pattern is used.

[0005] However, as described above, in the conventional pattern painting repair technique using a brush, a sprayer or an aerosol, in order to prevent the paint from adhering to a wide area other than the defective portion of the pattern paint, the paint is repaired at the time of repair. There is a problem that a mask must be applied to the surface of the object, the repair work becomes very complicated, and the hands or clothes of the worker may become dirty. Further, such a repair technique can be used only for repairing a painted object having a dot pattern. Therefore, when repairing a painted object other than the dot pattern, the operator is extremely complicated and skilled, for example, using a thin brush and paint to hand-draw the same pattern as the pattern painting. There is also a problem that it is necessary to rely on repair techniques that require skills.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and repairs a local defect of a painted pattern of a painted object quickly and easily irrespective of the form, color or shape of the pattern. It is an object of the present invention to provide means capable of performing the above.

[0007]

According to a first aspect of the present invention, which has been made to solve the above-mentioned problems, a method for repairing a locally-defected portion of a pattern paint on a paint object is provided. (A) preparing digital image data corresponding to a pattern painting of a painted object (for example, a wall portion of a building on which a design painting is applied), and (b) forming a shape corresponding to the pattern painting based on the digital image data. (C) A part of the transfer plate material is attached to a support member so that the concave and convex portions are exposed, and a pattern painting repair tool (stamp) is manufactured. ) After applying a paint that matches the color of the pattern paint to the irregularities of the pattern painting repair tool, press the irregularities against the part where the pattern paint of the painted object is missing, and apply the paint of the irregularities to the surface of the painted object. Transfer and repair the missing part of the above pattern paint It is characterized in that the. Here, specifically, the transfer plate material is, for example, an ultraviolet ray or a laser beam having irradiation characteristics corresponding to the pattern painting (in addition,
May be used in combination) on the surface of the photosensitive plate material containing the photocurable material to cause photocuring at the light-receiving portion of the photosensitive plate material. The light-cured portion is removed to form a concave portion, and the light-cured portion is left to form a convex portion.

In this pattern painting repair method, a pattern painting repair tool having an uneven portion having a shape corresponding to the pattern painting of a paint to be repaired is easily manufactured. Then, after applying a paint that matches the color tone of the pattern paint to the irregularities of the pattern paint repair tool, simply press the pattern paint repair tool against the defective part of the pattern paint, that is, simply press the stamp. The defective portion can be repaired by the simple operation described above. Therefore, there is no need for a mask for preventing paint from adhering to parts that do not require repair as in the case of the conventional repair method using a brush, a sprayer, or an aerosol, and the repair worker's hand or clothes, etc. It is possible to repair a defective portion of the pattern paint by an extremely quick and simple operation without applying paint to the surface. In the case where the pattern paint of the painted object is a multicolored color tone, a plurality of pattern paint repair tools are manufactured according to the color tone, and repair is performed using a different color paint for each of the pattern paint repair tools. Just do it.

In this method for repairing pattern paint,
Since the irregularities of the pattern painting repair tool are formed based on digital image data corresponding to the pattern painting, not only point-shaped pattern painting but also any complicated design pattern painting (for example, abstract pattern, geometric pattern) Pattern, wood grain, brick, etc.) can be easily repaired.

In the above-mentioned method for repairing a pattern paint, the digital image data is photographed by an image pickup means (for example, a scanner, a digital camera, etc.) on the surface of the paint to be repaired for a defective portion of the pattern paint, and the pattern paint is applied. It is preferable to create them by a method such as obtaining digital image data. In this way, digital image data corresponding to the pattern painting can be created very easily regardless of the pattern painting of the painted object.

In the above method for repairing a pattern coating, in the step of manufacturing a transfer plate material, a second original drawing (film) corresponding to the pattern coating is created based on the digital image data, and the second original drawing is used as a photosensitive plate. It is preferable that the photosensitive plate material is cured by irradiating the photosensitive plate material with a uniform ultraviolet ray or laser beam from the second original drawing side. In addition, as the second original drawing, a material that absorbs light having a wavelength of 300 to 500 nm, for example, a silver halide film, a non-silver halide film, or the like can be used. In this case, the mechanism for generating and irradiating the ultraviolet light or the laser beam becomes simple.

In addition, without using such a second original drawing, based on digital image data, an ultraviolet ray or a laser beam having an irradiation characteristic corresponding to the pattern painting is directly radiated to the surface of the photosensitive plate material to thereby form the photosensitive plate. The transfer plate material may be manufactured by curing the material. If you do this,
Since the second original drawing is not required, the material cost of the transfer plate material is reduced.

The photosensitive plate material used in the above-mentioned method for repairing a pattern coating includes, for example, a rubber molded product. Note that a part of the transfer plate material may be attached to the support member via an intermediate layer made of foam and having elasticity.
By doing so, the transfer plate material is easily elastically deformed, so that even if the portion to be repaired of the coating has irregularities, the portion can be surely painted (repaired).

The material of the photosensitive plate material is, for example, a polymer of a polymerizable monomer or chloroprene rubber, ethylene-chloroprene rubber, butyl rubber, silicone rubber, fluorine rubber, acrylic rubber, polysulfide rubber, natural rubber, butadiene rubber, isoprene. It may be formed of a material such as rubber, a foam of these rubbers, or a reaction product of these rubber components with a photocurable monomer, or a photocuring initiator.

Specifically, the photosensitive plate material used in the present invention may be any material which has been conventionally used for a printing plate or other photoresist, but is basically made of an acrylic monomer, unsaturated polyester or the like. More preferably, a liquid plate of the same type or a photosensitive plate material of the same type having a large amount of liquid monomer components is used.

Based on the type of thermoplastically processable polymer used, general processing conditions known per se for the polymer, such as temperature loading, plasticization, addition of auxiliaries, etc., should be considered. The thermoplastically processable polymers include, besides polyurethane and vinyl alcohol polymers, elastomeric rubbery polymers, such as, in particular, one-component polymers of butadiene and isoprene, of butadiene and of isoprene and of other copolymers. Copolymers with possible monomers, such as nitrile rubbers, such as butadiene / acrylonitrile copolymers having from 15 to 45% by weight of polymerized acrylonitrile, nitrile rubbers having carboxyl groups, nitrile rubbers containing vinyl chloride and styrene , Butadine and / or isoprene multiblock copolymers such as AB-2 block copolymer, ABA-3 block copolymer, ABC-3

Further, in the step of manufacturing the transfer plate material of the above-described method for repairing a pattern paint, the unevenness is formed by photo-curing. However, this is not the case. A laser beam such as a carbon dioxide laser having a corresponding irradiation characteristic is irradiated on the surface of a plate material containing a thermally decomposable or thermally sublimable material or a photodegradable material, and the light receiving portion of the plate material is decomposed (or melted) In this case, a concave portion may be formed, and a non-light receiving portion may be left to form a convex portion, so that a transfer plate material having a concave / convex portion having a shape corresponding to the pattern painting may be manufactured. In this case, it is preferable to use sponge or rubber as the plate material.

According to a second aspect of the present invention, there is provided a tool for repairing a locally painted portion of a pattern of a painted object, which has a concave / convex portion having a shape corresponding to the pattern painting of the painted object. The transfer plate material having elasticity provided is attached to the support member such that the concave and convex portions are exposed.

According to this pattern painting repair tool, after a paint that matches the pattern paint is applied to the uneven portion, the pattern paint repair tool is simply pressed against the defective portion of the pattern paint. The defective portion can be repaired by a simple operation of simply pressing the stamp. Therefore, the conventional repair method using a brush, a sprayer, or an aerosol does not require a mask for preventing paint from adhering to a portion that does not require repair, as in the case of a conventional repair method, and does not require a repair worker's hand or clothes. It is possible to repair a defective portion of the pattern paint by an extremely simple operation without attaching paint to the surface. In addition, since the uneven portion of the pattern painting repair tool can be formed in an arbitrary shape, it is possible to easily repair not only a dot pattern paint but also a pattern paint of any design.

In the pattern painting repair tool, the transfer plate material is formed of, for example, a rubber molding. In this case, it is preferable that an intermediate layer made of a foam and having elasticity is provided between the transfer plate material and the support member. In this case, the transfer plate material is easily elastically deformed by compression, so that even if the portion to be repaired of the coating has irregularities, the portion can be reliably painted (repaired). further,
By applying the coating with an appropriate pressure, it is possible to reduce bleeding of dots and line drawings, and it is possible to improve image accuracy. In the pattern painting repair tool, the transfer plate material may be formed of sponge or rubber.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below. FIG. 1 is a flowchart of a pattern painting repair process for repairing a defective portion of a pattern painting of a painted article according to the present invention. As shown in FIG. 1, in this pattern painting repairing process, first, in step S1, digital image data corresponding to the pattern painting of the paint to be repaired is prepared. The preparation of the digital image data is performed using, for example, an image processing system 1 as shown in FIG.

As shown in FIG. 2, the image processing system 1 includes an image database unit 2 and an image data creation unit 3
And a CG (computer graphic) data creation unit 4 and a printing unit 5. Here, the image database 2 stores digital type pattern painting image data corresponding to a pattern painting image (for example, an abstract pattern, a geometric pattern, a grain pattern, etc.) of a large number of painted objects created before. . The image database 2 is provided with an image database computer 6 that can extract or use desired data in a desired form from a large number of stored pattern painting image data.

The image data creating section 3 captures (photographs) the surface of the painted object or a photograph, drawing, or the like of the painted object, takes in the painted image of the painted object, and obtains a digital type painted image corresponding to the painted image. Create data. The image data creation unit 3 includes a scanner 7 (color image scanner) that captures the surface of a painted object or photographs and drawings thereof and converts the image into an analog electric signal, and a signal output from the scanner 7. An image processing computer 8 is provided for processing the electrical signals and converting them into digital pattern painting image data. The pattern painting image data created by the image processing computer 8 is sent to the CG data creation unit 4. Note that a digital camera is used instead of the scanner 7,
An image information providing device such as a CD-ROM may be provided. Further, the scanner 7 and the digital camera may be provided side by side so as to be selectively used according to the size of the painted object. CD
-Existing pattern painting image data may be read directly from a ROM or the like.

In the CG data creating section 4, the CG computer 9 corrects the pattern painting image data stored in the image database section 2 or the pattern painting image data created by the image data creating section 3, and repairs it. CG data corresponding to the pattern painting image of the painting object to be painted is created. In the printing unit 5, an image corresponding to the CG data created by the CG data creating unit 4 (computer 9) is printed using an ink-jet type photographic paper printer 10 to confirm the image. Printed on paper and output.

Thus, in this image processing system 1,
Digital image data (CG data) corresponding to a pattern painting image of a paint to be repaired is quickly and easily prepared. In this image processing system 1, if digital image data corresponding to the pattern painting of the object to be repaired already exists in the image database 2, the image data is used. Digital image data corresponding to the pattern painting image is newly created by imaging the surface of the object.

Next, in step S2, a tone reproduction process is performed on the digital image data (CG data), subsequently, in step S3, a tone correction process is performed, and then in step S4, based on the image data. Thus, a plate making film 25 (see FIG. 5) is created. The tone reproduction process, the tone correction process, and the plate making in steps S2 to S4 are performed using, for example, a film forming apparatus 11 as shown in FIG.

As shown in FIG.
Is a color plate data creating unit 12 that creates color plate data (film original data) using CG data (digital image data) input from the image processing system 1 (see FIG. 2); An image setter 13 for creating a plate making film 25 (see FIG. 5) using the plate data.

Here, the color plane data creating section 12 has a CG
A color plate data creating computer 14 is provided to create color plate data by performing data conversion processing, color separation / image division processing, finished size adjustment processing, gradation reproduction processing, gradation correction processing, and the like on the data. Have been. The color plane data is stored (saved) on the MO disk 15 when it is necessary to save the color plane data.

The color plate data creating computer 14 has a C
After performing data conversion processing, color separation / image division processing, and finishing size adjustment processing on the G data, various gradation reproduction processing is performed, and after the gradation reproduction processing, in some cases, before the gradation reproduction processing Is subjected to gradation correction processing to create color plane data.

The image setter 13 is provided with an image controller 16 and an automatic developing machine 17. When the tone reproduction method is the halftone dot method or the FM screen method, the image controller 16 performs a tone reproduction process (binarization process) on the color plate data. Further, the image controller 16 performs various controls of the automatic developing machine 17. On the other hand, the automatic developing machine 17 is
A plate making film 25 (negative film or positive film) having an image corresponding to the tone reproduction image is automatically created based on the tone reproduction image data input from Step 6.

The color plate data creating computer 14 and the image controller 16 are both computers that can perform tone reproduction processing and tone correction processing. The controller 16 is responsible for the tone reproduction processing (binarization processing) by the halftone method and the FM screen method, and the color plate data creating computer 14 is to perform other gradation reproduction processing (error diffusion dither method, density pattern method, And a tone correction process. It is needless to say that such an allotment can be changed in any way.

Next, in step S5, plate making of a transfer plate material is performed using the plate making film 25. In this plate-making process, basically, a plate-making film 25 (second original drawing) is attached to the surface of a photosensitive plate material, and the photosensitive plate material is irradiated with ultraviolet light or a laser beam through the plate-making film 25. While the portion corresponding to the transparent portion is cured by light curing, the uncured portion corresponding to the colored portion of the plate making film 25 is subjected to a developing process such as scraping using a brush, and the uncured portion is removed. Thus, an uneven shape corresponding to the image of the plate making film 25 is formed.

Hereinafter, the method of making a transfer plate material in step S5 will be described more specifically. As shown in FIG. 4, in this plate making, first, a photosensitive plate material 21 is prepared. The photosensitive plate material 21 includes a photosensitive layer 22, a transparent base film 23 (plastic sheet) attached to the back surface of the photosensitive layer 22, and a protective cover attached to the front surface of the photosensitive layer 22. And a layer 24 (plastic sheet). Here, the photosensitive layer 22 is
It contains a polymer binder, a monomer having an ethylenically unsaturated double bond, and a photocuring initiator, and when irradiated with ultraviolet rays or a laser beam, photocuring occurs to cure.
The portion that is not irradiated with ultraviolet light or laser beam, that is, the portion that has not been cured by photocuring, is relatively soft, and can be easily scraped in a solvent in which the plate material to be used is dissolved, for example, in water, for example, by rubbing with a brush or the like. Can be taken.

In this plate making, basically, a plate making film 25 (second original drawing) is adhered to the surface of the photosensitive plate material 21 by vacuum adhesion or the like, and then the photosensitive plate material 25 is placed from the plate making film 25 side. 21 (photosensitive layer 22) is irradiated with an ultraviolet ray or a laser beam (exposure process),
Irradiation is performed with the irradiation characteristics corresponding to the image of FIG.
Then, a developing process such as scraping with a brush is performed to remove the non-light-cured portion to form a concave portion and leave the photo-cured portion to form a convex portion, thereby forming a concave and convex shape corresponding to the original image. A transfer plate material provided on the surface is prepared.

More specifically, as shown in FIG. 5 (a), after removing the protective cover layer 24, a plate making film 25 is placed on the front side surface of the photosensitive layer 22 exposed outside. The surface 26 is arranged so as to be in contact with the photosensitive layer 22 (closed in vacuum). Next, as shown in FIG. 5B, the photosensitive plate material 21 (photosensitive layer 2
2) Irradiate ultraviolet rays or laser beam. Here, in a portion where the image film surface 26 of the plate making film 25 is not formed (that is, a transparent portion), an ultraviolet ray or a laser beam passes through the plate making film 25 and reaches the photosensitive layer 22 to be cured by photo-curing. A hardened portion 27 is formed. On the other hand, in the portion where the image film surface 26 of the plate making film 25 is formed (that is, in the opaque portion), the ultraviolet ray or the laser beam is absorbed by the image film surface 26, so that the photosensitive layer 2
2 and therefore the corresponding part of the photosensitive layer 22 remains uncured.

After that, as shown in FIG. 5C, after the plate making film 25 is removed, the front surface of the photosensitive layer 22 is subjected to a developing process such as scraping with a brush. At this time, the uncured portion of the photosensitive layer 22 is removed (scraped), while the cured portion 27 remains. Thus,
As shown in FIG. 5D, a transfer plate material 21 having an image displayed on the plate making film 25, that is, a concave and convex shape corresponding to the pattern painting of the painted object is obtained.

In place of such a transfer plate material making method (steps S4 to S5), as shown in step S4 '
A laser plate (laser engraving) method using a laser beam (for example, a CO ₂ laser) may be used. In this laser plate making method, when a sponge (or rubber) is irradiated with a laser beam, the sponge (or rubber)
Utilizes the property that is melted / decomposed or scraped. In the case of using such a laser plate making method, a transfer plate material having an uneven shape is manufactured by the following process.

That is, as shown in FIGS. 6 (a) to 6 (f), a concave portion of the plate material 30 is formed by using a laser device 31 capable of irradiating a laser beam 33 to an arbitrary position of the plate material 30. Laser beam 33 only on the part where
Is irradiated. Here, the laser device 31 scans the surface of the plate material 30 in a predetermined direction (X direction). If the aiming position of the laser device 31 during the scanning is a position where a concave portion is to be formed in the plate material 30, a laser beam is used. 33 is fired (on), and at this time, the sponge (or rubber) is removed from this part of the plate material 30 by melting / decomposing or shaving. On the other hand,
If the aiming position of the laser device 31 is a position where a projection is to be formed on the plate material 30, the emission of the laser beam 33 is stopped (off), and at this time, the sponge (or rubber) of this portion of the plate material 30 remains as it is. Thus, on the surface of the plate material 30,
An uneven shape corresponding to the tone reproduction image of the pattern painting of the painted object is formed.

More specifically, in the case of forming an uneven portion indicated by a profile 32 (broken line) on the plate material 30, for example,
The irradiation of the laser beam 33 is performed in the following procedure.
That is, first, as shown in FIG. 6A, scanning of the laser device 31 in the X direction is started. Then, FIG.
As shown in the figure, a laser beam 33 is emitted from a laser device 31 at a position where a concave portion is to be formed, and a laser beam 3 is emitted.
The sponge (or rubber) of the portion irradiated with 3 is melted and decomposed, and this portion becomes a concave portion.

[0043] Then, as shown in FIG. 6 (c), the firing of the laser beam 33 is stopped when the laser device 31 reaches the position P ₁ to form the protrusions. After this, FIG.
(D), the when the laser device 31 reaches the position P ₂ to form the recess again, the laser beam 33
Is resumed. Then, as shown in FIG. 6E, the laser device 3 is located at the position where the concave portion is to be formed again.
1 emits a laser beam 33,
The sponge (or rubber) of the portion irradiated with is melted and decomposed, and this portion becomes a concave portion. Thus, as shown in FIG. 6F, the projections 30a and the depressions 30b corresponding to the profile 32 are formed, the transfer plate material 30 is completed, and the scanning of the laser device 31 is stopped.

The laser device 31 scans or reproduces a tone reproduction image (print, positive film, etc.) based on tone reproduction image data directly input from a computer.
Is scanned based on the read image information. Therefore, in this case, it is not necessary to form the plate making film 25 as in the case of plate making of a photosensitive plate material (filmless).

In step S6, as shown in FIG. 7, a part of the transfer plate material 21 (30) is cut out (cut out), and a stamp plate material 35 is manufactured. It should be noted that a large number of stamp plate materials 3 are obtained from one transfer plate material 21 (30).
5 is cut out. Here, the transfer plate material 21 (30)
For example, the stamp plate 35 has a size of about 30 cm × 30 cm, and the stamp plate 35 is, for example, a circle having a diameter of 5 to 20 mm or a square having a side of 5 to 20 mm.

Next, in step S7, as shown in FIG. 8 (a) or 8 (b), a stamp plate material 35 prepared by a method relating to plate making of a photosensitive plate material, or a method relating to laser plate making. A support member 36 (handle) is attached using an adhesive or the like to the spread surface (back surface) of the stamp plate material 35 ′ formed on the side where the uneven portion (the portion corresponding to the pattern painting) is not formed. , Stamps S and S '(pattern painting repair tool) are completed. The support member 36 may be anything as long as it can be easily held by a worker, for example, cylindrical wood or the like.

Thereafter, in step S8, the stamp plate material 3
After applying a paint that matches the color tone of the pattern paint to be repaired to the uneven portion of 5, the uneven portion is pressed against the part where the pattern paint of the paint is missing, and the paint of the uneven portion is applied to the surface of the paint. Transfer and repair the missing part of the pattern paint. Here, as a method of attaching the paint to the uneven portion of the stamp plate material, the stamp may be directly immersed in the paint as usual, but the following method may be used. That is, a mesh material made of a natural fiber, a synthetic fiber, or a metal, such as a cloth or a fine mesh, is impregnated with a paint to be painted in advance, and a stamp is formed on the surface of the mesh material holding the paint. , A proper amount of paint is deposited on the surface of the plate material, and pressed against the above-mentioned defective portion to perform painting, whereby a design (image) having high sharpness can be obtained. Further, the problem that the portion of the stamp other than the paint-adhering surface is stained by the excess paint is also solved.

In this pattern painting repair method, stamps S and S 'having irregularities having a shape corresponding to the pattern painting of the paint to be repaired can be manufactured quickly and easily at low cost. Then, after applying a paint that matches the color tone of the pattern paint to the uneven portion of the stamp S,
The defective portion can be repaired by an operation of simply pressing the stamp S against a defective portion of the pattern paint, that is, a simple operation of simply pressing the stamp. Therefore, the conventional repair method using a brush, a sprayer, an aerosol, or the like does not require a mask as in the case, and does not attach paint to the hands or clothes of the repair worker. The missing part of the pattern paint can be repaired. In addition, when the pattern painting of the painted object has a multicolored color tone, a plurality of stamps S and S 'are manufactured according to the color tone or the number of colors, and these stamps S and S' are painted with different color paints. The repair may be performed sequentially.

Also, in this method for repairing a pattern paint,
Since the concave and convex portions of the stamp plate 35 (35 ') are formed based on digital image data corresponding to the pattern painting, not only the point-like pattern painting but also any complicated design pattern painting (for example, abstract). Repair can be easily performed on patterns, geometric patterns, wood grain patterns, brick patterns, and the like.

As shown in FIG. 8 (c), the stamp plate material 35 prepared by such a plate making method is used.
Foam (for example, sponge) between the support member 36 and
An elastic intermediate layer 37 may be provided. In this way, the stamp plate 35 is easily elastically compressed and deformed, so that even if there is unevenness in the part to be repaired of the painted object, it is possible to reliably apply the pattern painting (repair) to the part. In addition, bleeding and bleeding phenomena can be reduced by moderate pressure, and sharpness can be improved.
