<Information printing layer>
The woven fabric printed matter according to the present invention is a woven fabric printed matter in which the edging printed portion is a printed portion having an area of 20% or more of an information printing layer having a length in the long side direction of 70 mm or less. Here, the information printing layer is a printing layer composed of a border printing unit and visual information. Further, the border printing unit 1 refers to one continuous area printed so as to border the visual information 2 shown in FIG.

In FIG. 1, the length 3 in the long side direction represents the length in the long side direction of the information printing layer. Here, the length in the long side direction means the longest of the lengths of each side for a polygon, the diameter for a circle, and the length of the long axis for an ellipse.

The area of the border printing portion can be obtained by the following method. First, the cloth printed matter is fixed to the wall, and the information printing layer is photographed at a magnification of 2 times optical with a digital camera attached to a tripod from a distance of 20 cm from the cloth printed matter. Next, the image is converted to grayscale, and the image analysis software "ImageJ" (manufactured by the National Institutes of Health) is used to set the Thrashold condition to Auto, the Dark Bakeround, the Analize condition to the Analize particle, and the Size (pixel) to 5-. The area of the border printing portion and the area of the information printing layer are measured with Infinity and Circularity set to 0.00-1.00. The measured value is calculated by the following formula, and the area ratio of the edging portion is calculated.

Border area ratio (%) = Border area area (pixel) / Information printing layer area (pixel) x 100

Since the border printing unit is a printing unit having an area of 20% or more of the information printing layer, the ease of finding fine visual information is improved. More preferably, the border printing unit is a printing unit having an area of 40% or more of the information printing layer. The fine visual information here refers to visual information having a line width of 300 μm or less, and the finer visual information refers to visual information having a line width of 150 μm or less. The finer visual information is visual information having a line width of 100 μm or less. Since such fine visual information has a small size and is difficult to have a contrast with the surrounding fabric, it is effective to have a border printing portion in order to improve the ease of finding.

Further, in the cloth printed matter according to the present invention, the average value L ^* a ^* b ^* color system coordinates (L ^* ₁ , a ^* ₁ , b ^* ₁ ) obtained by measuring any three points of the cloth and the border printing unit The color difference (ΔE ₁₂ ) obtained from the average value L ^* a ^* b ^* color system coordinates (L ^* ₂ , a ^* ₂ , b ^* ₂ ) obtained by measuring any three points of the above satisfies Equation 1. Is preferable.

Equation 1:
ΔE ₁₂ = [(L ^* _1- L ^* ₂ ) ² + (a ^* _1- a ^* ₂ ) ² + (b ^* _1- b ^* ₂ ) ² ] ^1/2 > 15

By satisfying Equation 1, it becomes easy to find the visual information in the fabric. In addition, in order to make it easier to find out, it is preferable that ΔE ₁₂ is 30 or more.

Further, it is preferable that the border printing portion contains a polyester resin. The polyester resin has good adhesion to the cloth containing polyester fibers, and has resistance to friction of the cloth and damage due to washing. Further, by including a hardening agent in the border printing portion, the resistance to damage caused by friction and washing of the fabric is further improved. The curing agent contained in the border printing portion is not limited, but an isocyanate compound is preferably used. By cross-linking the isocyanate compound, a cross-linked structure consisting of at least one of a urethane bond and a urea bond can be formed, and the durability of the border printing portion can be enhanced.

<Manufacturing method of printed fabric>
Next, a method for producing a woven fabric printed matter according to the present invention will be described.

The woven fabric printed matter according to the present invention can be produced by printing an information printing layer on the woven fabric. The information printing layer can be formed by screen printing, inkjet printing, sublimation transfer printing, and pad printing. For pad printing, (i) ink is placed on the plate surface of the concave printing plate and (ii) scraped off with a metal doctor blade, or with a ring-shaped ceramic or special metal edge that acts as a doctor blade. By putting ink in the ink cup and scraping the plate surface with the ink cup, the concave part of the (iii) concave printing plate is filled with ink, and the ink is transferred to a flexible pad surface such as silicone rubber. iv) This is a type of offset printing in which printing is performed by pressing the ink-adhered surface of the pad against the object to be printed. Pad printing is preferably used because the printing speed is faster than other methods and the printed matter without bleeding can be produced by adjusting the drying speed of the ink.

The intaglio printing plate used in pad printing is not limited to the following intaglio printing plates, but (a) a metal printing plate produced by etching carbon steel or the like, and (b) a resin layer containing a resin and a pigment are laser-engraved. It is possible to use a resin printing plate having recesses formed by the above, or (c) a resin printing plate having recesses formed by exposing and developing the photosensitive resin layer.

Of these, the printing plate formed from the photosensitive resin layer is preferable because it can provide a printed matter having high accuracy of the line width of the concave portion and high reproducibility and good visibility with respect to the original image. The photosensitive resin layer used in such a resin printing plate is preferably formed from a photosensitive resin composition containing at least a binder polymer, a compound having an ethylenic double bond, and a photopolymerization initiator. As a printing plate material having such a photosensitive resin layer, PU52LR (manufactured by Toray Industries, Inc.) and the like are known.

It is preferable to use a printing plate having halftone dots in the recesses of the printing plate. By having halftone dots in the recesses, when ink is placed on the plate surface of the intaglio printing plate and scraped with a metal doctor blade, uneven scraping of the ink can be prevented, so that a uniform color printing layer can be prevented. Can be formed.

Further, it is preferable to use a printing plate in which the height difference between the top of the halftone dots provided in the recesses of the printing plate and the deepest portion in the depth direction is 40 to 120 μm. When it is 40 μm or more, a printing layer having a sufficient density can be formed, and when it is 120 μm or less, the amount of ink transferred to the cloth is not too large when pad printing is performed on the cloth, and the back side of the cloth is used. It is possible to prevent the ink from settling on the surface.

Further, the size of the halftone dots formed in the recesses of the printing plate is preferably 50 μm or less. By setting the size of the halftone dots to 50 μm or less, it is possible to suppress deterioration of the visibility of the printed matter due to the halftone dot traces transferred to the print layer.

Hereinafter, the present invention will be described in detail with reference to Examples.
