Description
Technical Field
The present invention relates to a method for producing a resin gravure printing plate for printing visual information on a fabric and a method for producing a fabric printed matter.
Background
A fabric as a fiber product displays various visual information such as a production source, a size, a raw material, a product name, and attention information on handling. As an information display method, there is a method of sewing a label on which information is recorded, but in underwear or the like in which a label is in direct contact with the skin, there is a fear of irritating the wearer, and therefore, a method of directly displaying information on a fabric without using a label while paying attention to comfort has been proposed. As a method for directly displaying information on a fabric, a method using pad printing (pad printing) as disclosed in patent document 1 has been proposed.
Pad printing is performed by the following steps. Ink is filled into the concave portion of the image portion of the gravure plate by placing the ink on the plate surface of the gravure plate and scraping the ink with a metal blade, or by placing the ink in an annular ceramic or special metal edged ink cup serving as a blade and scraping the plate surface with the ink cup. This is one type of offset printing in which printing is performed by transferring the ink onto a transfer surface of a flexible transfer material such as silicone rubber and pressing the ink-adhering surface of the transfer material against a printing object.
In pad printing, in general, the depth and shape of the recessed portion greatly affect the appearance of the printed matter. The depth adjustment of the recess is typically adjusted as follows: a positive original image film is adhered to a photosensitive resin printing plate precursor, and ultraviolet irradiation is performed, and then a halftone dot mask (screen film) is further adhered to the film and ultraviolet irradiation is performed, whereby a convex halftone dot is formed inside a concave portion to adjust the depth of the concave portion to an appropriate depth (for example, patent document 2).

Disclosure of Invention
Problems to be solved by the invention
However, in patent document 1, since the depth of the gravure printing plate is adjusted by etching, when the concave portion described in patent document 1 is formed, fine characters or numerals are worn out, and as a result, there is a problem that the characters or numerals cannot be visually confirmed in the printed matter. In addition, in patent document 2, since it is necessary to attach a film twice in order to form a concave portion, particularly in an image having many fine characters or numerals, abrasion of characters due to poor adhesion is likely to occur, and in some cases, it is necessary to perform plate making again, which causes a problem of an increase in process time.
Accordingly, an object of the present invention is to provide a method for manufacturing a resin gravure printing plate for printing fine visual information on a fabric in a reproducible manner while reducing plate making failures, and a method for manufacturing a fabric printed matter.

Detailed Description
Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments, and can be implemented by being variously modified according to the purpose or application.
In the present invention, the image portion refers to a recessed portion formed on the resin gravure printing plate, and the original image portion is a region on the original image film that gives the shape of the image portion. Further, the image part and the original image part contain visual information.
< visual information >
The fabric printed matter according to the present invention includes visual information. Here, the visual information refers to information that is visually related, such as characters, symbols, codes, numerals, figures, and patterns. The term "visually appealing" means information that can be visually recognized regardless of the presence or absence of design. Information that can be identified by light reflected by or emitted from the substance is preferable. Of course combinations with colors are also possible. Information for the following purposes is illustrated.
Trade name, trademark, service mark, house mark, company exclusive mark (house mark), group display, and trade name.
Characters (characters), images (pictures), dot markers, and the like. They also impart aesthetics, pleasure, feel, etc. to the person seeing them.
Quality display, processing method, manufacturing date, lifetime, manufacturing lot number, matrix-type two-dimensional code known as "QR code" (registered trademark), and the like. They are important information for the producer, distributor or consumer.
Preferably, the visual information that can be effectively used in the printed matter of the present invention includes at least one of a quality display mark, a processing method display mark, a manufacturing lot number, and a matrix-type two-dimensional code.
The original image film is used in the exposure of the present invention. The original image film needs to have a positive image and needs to have halftone dots within the original image portion. Here, the halftone dots need only be included in at least the inner side of the original image portion. The shape of the halftone dot is preferably a circle, an ellipse, or a quadrangle, and a plurality of shapes may be mixed. By providing a halftone dot screen in the original image portion, film sticking during exposure can be reduced from 2 times to 1 time, and plate making defects such as dust adhesion and sticking defects can be reduced. In particular, when a resin gravure printing plate having a fine image portion such as a character, a numeral, a symbol, or a code is subjected to plate making, image abrasion due to sticking failure can be prevented.
The total area ratio of halftone dots present in the original image portion according to the present invention needs to be 3% or more and 20% or less with respect to the original image portion. The area ratio is represented by the ratio of the total area of the halftone dots of the blank to the area of the original image portion. The area ratio of the halftone dots can be measured on the original image portion of the positive film using a positive color filter and using a michael white transmission densitometer "TR-927" (manufactured by Kollmorgen Instruments Corp.). In the present invention, the average value of the measurement results is calculated for 10 dots arbitrarily selected on the original image portion of the original image film, and the calculated value is set as the area ratio of the halftone dots. The area ratio of the halftone dots is preferably 3% or more, more preferably 5% or more, from the viewpoint of eliminating excessive ink scraping caused by the blade falling into the recessed portion when scraping excess ink present on the surface of the resin gravure printing plate for cloth using a blade or the like. From the viewpoint of adjusting the ink amount at the time of printing by deepening the depth of the recessed portion of the resin gravure printing plate, the area ratio of the halftone dots is preferably 20% or less, and more preferably 15% or less.
From the viewpoint of eliminating the scraping unevenness of the ink caused by the blade sinking into the concave portion, the diameter of the halftone dot present in the original image portion is preferably 10 μm or more, and more preferably 15 μm or more. From the viewpoint of adjusting the ink amount at the time of printing by deepening the depth of the resin gravure printing plate, the diameter of the halftone dot is preferably 50 μm or less, more preferably 40 μm or less. Here, the halftone dot diameter refers to its diameter if the halftone dot is circular, the major axis length if the halftone dot is elliptical, and the longer one of its diagonal lines if the halftone dot is quadrangular.
The size of the visual information constituting the original image portion according to the present invention needs to be 600 μm or more and 4000 μm or less. As shown in fig. 1, the size of the visual information is defined by the length of the long side 3 of the rectangle surrounding the visual information 1. Here, each side of the rectangle surrounding the visual information is a tangent line of the visual information. The tangent line of the visual information is a line having at least one point or more of contact with the visual information. In FIG. 1, each side of the rectangle has a vertical axis P with visual information1~P4The indicated contacts.
When a plurality of rectangles surrounding visual information can be defined, a rectangle having the smallest length of the short side 2 is used.
From the viewpoint of visual confirmation in a printed matter, the size of visual information constituting the original image portion is preferably 600 μm or more, and more preferably 1400 μm or more. From the viewpoint of printing more visual information in the printed matter, the size of the visual information constituting the original image portion is preferably 4000 μm or less, more preferably 3500 μm or less, and still more preferably 3000 μm or less.
Next, an example of a method for producing a resin gravure printing plate for fabric according to the present invention will be described. Although an example of the production method will be described below, the production method of the resin gravure printing plate for fabric according to the present invention is not limited to this.
The resin intaglio printing plate for fabric according to the present invention is obtained by sequentially performing an exposure step and a development step on a photosensitive resin printing plate precursor. The exposure step includes a step of performing exposure using an original image film having an original image portion and halftone dots inside the original image portion.
First, a halftone dot panel is formed integrally with an original image portion, and an original image film integrated with the original image portion and the halftone dot panel is produced. Examples of the method for producing the original image film include laser ablation, image photocopiers, ink jet printing, and the like. From the viewpoint of reproducibility of the high-definition halftone dots, a method of manufacturing by using laser ablation or an image photocopier is preferable.
Then, when the photosensitive resin printing plate precursor is provided with a cover film, the cover film is peeled off. The original image film is brought into close contact with the photosensitive resin layer and exposed to light, whereby an image portion is formed and halftone dots are formed in the concave portions, thereby adjusting the depth of the concave portions.
The exposure can be performed by ultraviolet light, and can be performed using a high-pressure mercury lamp, an ultrahigh-pressure mercury lamp, a metal halide lamp, a xenon lamp, a carbon arc lamp, a chemical lamp, or the like, which can generally irradiate a wavelength of 300 to 400 nm.
Next, the photosensitive resin printing plate precursor is immersed in a developer, and uncured portions are removed without exposure to light. The uncured portions are wiped out, for example, with a brush type developing device having a brush, to form a relief image. Further, a spray type developing device can be used in addition to the brush type developing device. The developer can use a solution containing lower ethanol, and further can use a solution containing a surfactant.
The liquid temperature during development is preferably 15 to 40 ℃. After the relief image is formed, the relief image is dried at 50 to 70 ℃ for about 10 minutes, and if necessary, an actinic ray treatment is performed in the atmosphere or in a vacuum to form a post-exposure step, thereby obtaining a resin gravure printing plate.
Some photosensitive resin printing plate precursors are capable of providing a printed matter having high accuracy of line width of recessed portions and high reproducibility and good visual confirmation. The photosensitive resin layer used for such a photosensitive resin printing plate precursor can be a known photosensitive resin plate, but is preferably formed of at least a binder polymer (binder polymer), a compound having an ethylenic double bond, and a photosensitive resin composition containing a photopolymerization initiator. As a printing plate material having such a photosensitive resin layer, a photosensitive resin printing plate precursor "PU 52 LR" (manufactured by tokyo corporation) and the like are known.
Next, a method for producing a fabric printed matter of the present invention will be described.
In the method of the present invention, a fabric printed matter is produced by a step of producing a resin gravure printing plate and a step of printing a fabric using the obtained resin gravure printing plate. Preferably, the following are carried out in sequence: a step of producing a resin intaglio printing plate using the method of the present invention, a filling step of filling ink into an image portion of the resin intaglio printing plate, a first transfer step of transferring the ink filled into the image portion to a transfer body, and a second transfer step of transferring the ink transferred to the transfer body to a fabric to form a printed matter, thereby producing a fabric printed matter.
In the present invention, a fabric is produced by printing visual information such as characters, numerals, symbols, or codes on the fabric. The printing method can be formed by screen printing, ink jet printing, or pad printing, but pad printing is preferable from the viewpoint of printing fine visual information.
Here, an example of pad printing will be described.
In pad printing, first, ink as a recording material is applied to a gravure printing plate. Thereafter, the surface of the gravure printing plate is scraped with a doctor blade, thereby removing the excess ink on the gravure printing plate and filling the recessed portions as image portions with the ink.
Next, a flexible pad such as silicone rubber as a transfer body is pressed against the image portion of the gravure printing plate, and the ink filled in the image portion is transferred to the surface of the pad. Then, the ink-adhering surface of the spacer is pressed against the object to be printed, thereby forming a printing element having the same shape as the image portion of the gravure printing plate on the surface of the object to be printed.
In the present invention, the printed fabric is obtained by producing a fabric according to a usual method, and may be any of a woven fabric, a knitted fabric, and a nonwoven fabric, and may be a fabric of a woven/knitted mixed woven fabric, for example.
The weave of the woven fabric is preferably: plain weave, twill weave, satin weave and other three primary weaves; plain weave change weave, twill change weave, satin change weave and other change weaves; special textures such as a honeycomb texture, a molded yarn texture, and a crepe texture; single-double structures such as warp double structure and weft double structure; double-sided heterochromatic pattern tissue, bag tissue, double-sided velvet, towel, seal skin, velour and other warp raising tissues; raised weft texture such as velveteen, velvet, corduroy, etc.; nonwoven fabrics such as gauze, and jacquard, and the like. The weaving is preferably performed by an organic loom (e.g., a fly loom) or an inorganic loom (e.g., a rapier loom, a sheet loom, a water jet loom, or an air jet loom).
The knitted fabric may be a weft knitted fabric, a warp knitted fabric, or the like. As for the structure of the knitted fabric, the weft knitting is preferably flat knitting, rib knitting, double rib knitting, pearl knitting, tuck knitting, float knitting, half bed knitting, loop transfer knitting, terry knitting, or the like, and the warp knitting is preferably single bar flat knitting, single satin knitting, double bar warp knitting, pile knitting, jacquard knitting, or the like. In addition, the woven fabric may be a single layer or may be a multilayer having 2 or more layers. The knitting is preferably performed by a circular knitting machine, a flat knitting machine such as a flat knitting machine or a cotton knitting machine, a warp knitting machine, a raschel knitting machine, a milanian knitting machine, or the like.
In the present invention, the fabric is preferably a woven fabric or a knitted fabric, and more preferably a knitted fabric.
In the present invention, the fabric may be a fabric in which fibers constituting the fabric include multicolor fibers. As a specific example, a texture in which a dark color and a light color are mixed as in a wood grain is preferable, and for example, a mixed color fabric is known as a fabric including white fibers and black fibers. As the fibers, multifilament yarns and monofilament yarns can be used, and as a fabric including such fibers, there is a mixed-color fabric.
In the present invention, polyester fibers can be used for the printed fabric. Any of polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and the like can be used as the polyester-based fiber, but the polyethylene terephthalate-based fiber has good hand and gloss, and easy-care properties such as difficulty in wrinkling, and is preferable as a fiber material constituting a stretchable fabric. Further, the polyethylene terephthalate fiber is preferably used in combination with the polyurethane urea elastic fiber, and can be made into a favorable stretch fabric. Polyester fibers are usually dyed with a disperse dye, but the disperse dye may have poor fastness such as color bleeding. Therefore, it is preferable to use a cationic-dyeable polyester fiber which can be dyed well with a cationic dye. The thickness of the fabric is preferably 1000 μm or less from the viewpoint of texture and stretchability.
In the present invention, the fabric is preferably used as a garment. For example, the following modes can be applied: various visual information such as manufacturing source, size, raw material, product name, attention information on handling, etc. is directly printed on the clothes. By using the present invention, a printed matter in which fine visual information can be visually confirmed can be improved.

A black carbon film TK100 (manufactured by Takano machine) was attached to an outer drum type plate aligner "CDI SPARK" (manufactured by Esko-Graphics) having a fiber laser emitting light in the infrared ray so that the base material side was in contact with the drum. Test patterns in which 10 japanese characters in which an original image portion of the shape shown in fig. 2 and a halftone dot blank therein are present were drawn under conditions of a laser output of 9kW and a drum rotation speed of 400rpm, and positive original image films 1 to 8 were produced. Table 1 shows the method of producing the original image film, the size of the visual information, the number of halftone dot lines per 1 inch (referred to as "LPI" in the table), the area ratio of halftone dots in the original image portion, and the halftone dot diameter. These original image films were used in examples 1 to 5 and comparative examples 1 to 3, respectively, as shown in table 2. For example, the original image film 1 is used in embodiment 1. In the original image film 1, 10 japanese characters shown in fig. 2 are arranged, and the size of visual information defined in the present invention is 2500 μm for each character, and further, the area ratio of halftone dots is 10%, and the average halftone dot diameter is 36 μm in the case of a circle.
1.2 measurement of diameter of halftone dot
Next, 10 halftone dots of the original image portion were arbitrarily selected for each original image film, and observed under a lens Z250 and a magnification of 250 times using a digital microscope "VHX-2000" (manufactured by yokeshi), and the diameters of the halftone dots were measured. The average of the diameters of 10 halftone dots is set as the diameter of the halftone dot.
1.3 determination of the proportion of the area of the halftone dots within the original image portion
For each original image film, 10 halftone dots within the original image section are arbitrarily selected. The transmittance is determined for the selected dots by dot area (dot area) + "positive color filter" K "using a mike white transmission density meter" TR-927 "(manufactured by Kollmorgen Instruments Corp.), and the area ratio of the halftone dots is determined from the transmittance. The average value of the measurement results of the 10 halftone dots is set as the area ratio of the halftone dots in the original image portion.
1.4 production of resin gravure printing plates
A photosensitive resin printing plate precursor PU52LR (manufactured by Toray corporation) of 7 cm. times.14 cm was prepared. Only the cover film made of a prepreg was peeled off from the printing plate precursor. Further, a layer having a thickness of 1 μm was present on the surface of the peeled photosensitive resin printing plate precursor to assist the peeling. Each of the original image films of examples 1 to 5 and comparative examples 1 to 3 shown in Table 2 was vacuum-adhered to the photosensitive resin layer side of the photosensitive resin printing plate precursor of 7cm × 14cm, and exposed to light using a chemical lamp FL20 SBL-36020 Watts (manufactured by Mitsubishi electro Osram) under a gray scale sensitivity of 13 ± 1 level. This will be referred to as "main exposure" hereinafter. ) Then, development was performed for 1 minute in an ethanol aqueous solution (ethanol/water =80/20 (mass ratio)) at a liquid temperature of 25 ℃ by a brush developing apparatus, and drying was performed for 10 minutes at 60 ℃. Further, post exposure was performed using a chemical lamp FL20 SBL-36020 Watts (manufactured by Mitsubishi electric Osran) under the same conditions as the main exposure, to obtain resin gravure printing plates corresponding to examples 1 to 5 and comparative examples 1 to 3.
1.5 evaluation of plate-making defective Rate
Halftone dots corresponding to 10 points where the diameters of the halftone dots of the original image film were measured, which were present on the image portion of the obtained resin gravure printing plate, were selected. The halftone dot diameter of the selected resin gravure printing plate was measured at a magnification of 250 times under a lens Z250 using a digital microscope "VHX-2000" (manufactured by yonzhi, inc.), and the average value was set as the average halftone dot diameter. When the average diameter of the halftone dots of the resin gravure printing plate is greater than the average diameter of the halftone dots of the original image film by 30% or more, it is determined that the plate making is defective. Further, when 100 sheets were produced, the proportion of plate making failures was 5% or more.
1.6 visual confirmation of visual information
The resin gravure printing plates of examples 1 to 5 and comparative examples 1 to 3 were mounted on a hermetic6-12 universal (pad printing press, manufactured by TAMPOPRINT), and printed on "peaace FIT" (registered trademark) BLACK (manufactured by Aeon Topvalu) as a fabric by once rubbing with an ink prepared by adding 3g of a curing agent HARDENER n.2 (manufactured by EPTA) to 20g of URETHANE2502 EO BLACK (manufactured by EPTA), and then transferring the resultant to a pad. The visual confirmation of the visual information printed on the fabric was visually confirmed by 5 judges. The measured vision of both eyes including corrected vision of the examiner is 0.7 or more, and the distance between the sample and the eyes is 50 cm. Each of the judges read 10 characters printed on the fabric, and visually confirm all the characters read. The criterion for the determination is as follows.
A: the number of people capable of being visually confirmed is 5
B: the number of people who can be confirmed visually is 3-4
C: the number of visually identifiable people is 0-2.
1.7 evaluation results
By the above-described method, an original image film, a resin gravure printing plate, and a fabric printed matter were produced and evaluated. The evaluation results are shown in table 2.
2. Comparative example 4
A black carbon film TK100 (manufactured by Takano machine) was attached to an outer drum type plate aligner "CDI SPARK" (manufactured by Esko-Graphics) having a fiber laser emitting light in the infrared ray so that the base material side was in contact with the drum. The test pattern having no halftone dots in the original image portion shown in table 1 was drawn under the conditions of a laser output of 9kW and a drum rotation speed of 400rpm, and an original image film 9 was produced.
The prepreg covered with the film was peeled from the photosensitive resin printing plate precursor PU52LR of 7cm X14 cm, and the original image film was vacuum-adhered thereto, and exposed to light (first exposure) using a chemical lamp FL20 SBL-36020 Watts (manufactured by Mitsubishi electro Osran) under a gray scale sensitivity of 11. + -. 1 scale. Next, the original image film was peeled off, and a 250LPI 10% halftone dot panel (a proportion of a white area in a black matrix of 10%) was vacuum-adhered, and exposure was performed under the same conditions as the main exposure (second exposure). After that, the vacuum-applied halftone dot screen was peeled off, and then developed by a brush developing device for 1 minute in an ethanol aqueous solution (ethanol/water =80/20 (mass ratio)) having a liquid temperature of 25 ℃, and dried at 60 ℃ for 10 minutes. Further, post-exposure was performed using a chemical lamp FL20 SBL-36020 Watts (manufactured by Mitsubishi electro Osran) under the same conditions as the main exposure, to obtain a resin gravure plate. The plate was made 100 times by this method. When evaluated by the method described in 1.5, the plate making defect rate was 5%.
