Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a printed product in which various change patterns are developed depending on an angle of a line of sight due to an optical interference action, and a three-dimensional pattern is developed.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in the field of optics, it has been common practice to form moiré patterns using woodgrain interference fringes and mottle using a photograph. The optical interference fringe by the above-mentioned photographic method has a function of superimposing a thin line on a transparent or translucent sheet, and causing an observer's eyes to have an illusion as if a solid exists inside the sheet. In the printing and photographic industries, moire is disliked as a print defect, and many studies have been made to prevent moiré.

[0003] In recent years, there has been a demand for the development of printed products in which moiré patterns such as optical interference fringes are imparted to textiles such as clothing. However, no improvement has been made to respond to this request.

[0004]

[Problems to be solved by the invention]

 An object of the present invention is to provide a printed product in which various change patterns are developed depending on an angle of a line of sight and a three-dimensional pattern is developed by an optical interference effect in order to achieve the above object.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a printed product having a three-dimensional pattern according to the present invention is a printed product in which at least two printed layers are superimposed on a surface of a base material to exhibit an optical interference fringe pattern, and the printed layer is a dot. , A line, an oblique line, a dotted line, a dashed line, a wavy line, a lattice, and at least one pattern selected from halftone dots of an arbitrary shape, and the printed pattern is formed at a density of 10 to 75 lines or a number per inch width. The pattern of at least two layers is printed using a screen printing plate shifted by a predetermined angle. With this configuration, it is possible to realize a printed product in which various change patterns are exhibited depending on the angle of the line of sight due to the light interference effect and a three-dimensional pattern is exhibited. When the density of the printed pattern is less than 10 lines or the number per 1 inch width, the light interference effect is unlikely to occur. Conversely, when the density exceeds 75 lines or the number, the light interference effect is unlikely to occur.

[0006]

[Embodiment of the invention]

 In the processed product of the present invention, the preferable range of the print pattern density is 16 to 55 lines or the number per inch width. When the density is in the above range, the light interference action is efficiently exhibited.

In the processed product, it is preferable that the pattern of the first layer and the pattern of the second and subsequent layers are substantially the same. Here, “substantially” means that the patterns are almost the same, although slight differences are allowed. If the pattern of the first layer and the pattern of the second layer and thereafter are substantially the same, the light interference effect is efficiently exhibited. In particular, it is preferable that the densities per inch of the first layer pattern and the second and subsequent patterns are substantially the same.

In the processed product, the screen printing plate used for the first layer pattern and the screen printing plate used for the second and subsequent patterns are shifted by an angle within a range of 1 to 20 degrees. Is preferred. If the deviation is within this range, the optical interference action is efficiently exhibited. Even outside the above range, some light interference effects are exhibited.

In the processed product, it is preferable that the pattern of the first layer and the patterns of the second and subsequent layers are formed in the same color or different colors. When forming in different colors, it is also effective to combine one color with one transparent color.

In the processed product, it is preferable that the thickness of the printed layer of the first pattern and the second and subsequent patterns is in the range of 8 to 80 μm.

[0011] In the processed product, the substrate is preferably at least one selected from a woven fabric, a knitted fabric, a nonwoven fabric, and a sheet.

The processed product is formed by screen printing. As the ink to be used, a thermosetting type, an evaporative drying type using a solvent, an ultraviolet curing type, or the like can be used, and a water-based ink or an oil-based ink can be used.

Next, an embodiment of the present invention will be described with reference to the drawings.

Example 1 In the following examples and comparative examples, experiments were performed under the following conditions. (1) Fabric The fabric used was a plain nylon fabric (blue dyed fabric of taffeta, basis weight 110 g / cm ² ). (2) Screen printing plate The screen printing plate used was a gauze fabric made of polyester fiber having a roughness of 80 mesh (the number of meshes per inch) and a screen printing plate having a screen thickness of 150 μm and 30 lines (30 lines). Pcs / inch) with a halftone dot pattern having a porosity of 60%. (3) Ink The ink used was an oil-based polyurethane resin (cyclohexanone solution having a resin component of about 35 to 40% by weight) and a binder obtained by adding about 35% by weight of a white pigment (for the first layer). A binder prepared by adding about 20% by weight of a red pigment to the binder (for the second layer) was prepared. (4) Printing operation The first plate is printed with white ink, lightly dried (touch dry), and then the second plate is printed with red ink using a clean printing plate in which the halftone dot pattern is shifted by a predetermined angle. Was printed. After the two-color printing, a drying heat treatment was performed at 120 ° C. for 5 minutes.

FIG. 1 is a schematic view showing a printing process according to an embodiment of the present invention. As shown in FIG. 1, a screen printing plate 2 having a pattern 4 was placed on a fabric 1, and ink was screen-printed. Reference numeral 3 denotes a shielding sheet that does not pass ink.

Next, the same pattern 7 as that of the first layer was shifted at an angle in the range of 0 to 20 degrees to form a second layer pattern. Reference numeral 5 denotes a second-layer screen printing plate, and reference numeral 6 denotes a shielding sheet that does not pass ink.

In FIG. 1, for the sake of explanation, two printing plates having patterns arranged at predetermined angles are used as printing plates.

FIGS. 2 to 6 are views for explaining a printed product formed as described above. First, FIG. 2 shows a comparative example, in which the deviation of the pattern angle between the first screen printing plate 2 and the second screen printing plate 5 is 0 degree. In this case, since the patterns are simply double-layered, the change pattern does not appear naturally.

Next, FIG. 3 (Example) shows a case where the angle between the patterns of the first screen printing plate 2 and the second screen printing plate 5 is 5 degrees. In this case, multiple large diamond-shaped rectangular patterns appeared.

Next, FIG. 4 (embodiment) shows a case where the angle between the patterns of the first screen printing plate 2 and the second screen printing plate 5 is 10 degrees. In this case as well, a rectangular pattern slightly smaller than that in FIG.

Next, FIG. 5 (embodiment) shows a case where the angle deviation of the pattern between the first screen printing plate 2 and the second screen printing plate 5 is 15 degrees. In this case, a relatively simple diamond was formed, and a rectangular pattern slightly smaller than that in FIG. 4 appeared.

Next, FIG. 6 (embodiment) shows a case where the angle of the pattern angle between the first screen printing plate 2 and the second screen printing plate 5 is 20 degrees. In this case as well, a relatively simple diamond was formed, and a rectangular pattern slightly smaller than that in FIG. 5 appeared.

As described in the above Examples and Comparative Examples, the printed matter undergoes various changes such as wood-grained interference fringes, moire-like mottle, or fluctuation depending on the angle of the line of sight due to light interference. A printed product with a pattern and a three-dimensional pattern was realized.

[0024] The printed product obtained as described above is useful for design patterns, marks, etc. of clothing.
