Description

  The present invention relates to a decorative processed sheet that can be used for various applications such as a clear file, various packaging boxes, cards, POPs, and the like, and a method for manufacturing the decorative processed sheet.

  Conventionally, various processed sheets, composite sheets, and surface decorative sheets exist as sheets used for decoration on the surface of a plastic sheet and used for clear files, cards, packaging boxes, signboards, and other advertising POPs. For example, it is known that a polypropylene resin sheet (PP sheet) is used as a base material, a multicolor pattern or a metallic luster pattern is printed on the back surface, and a silver film is uniformly deposited thereon.

  Moreover, as shown in Patent Document 1, after performing multicolor printing on one side of a transparent plastic film, a metallic gloss layer is formed on the printed surface by vapor deposition or lamination, and the appearance of impressions differing between the front side and the back side A double-sided decorative sheet that has been realized has been realized. As another example, a vapor-deposited film having light scattering reflectivity, such as a silver vapor-deposited film, is laminated on one side of the sheet, and an anchor layer is formed on the surface of the vapor-deposited film, and various printing can be performed thereon. A printable light-scattering / reflecting vapor deposition sheet is also disclosed (Patent Document 2).

  Further, Patent Document 3 discloses a processed paper that can be produced in a small amount at a low cost with a wide variety of products such as a desired color, darkness, and gloss level. According to this, a metal is applied to the surface of a paper substrate. A color film layer, for example, a silver plastic film is vapor-deposited, and a printing layer is formed on the surface of the metal color film layer by offset printing of a desired color ink so that the surface of the paper material exhibits a colored metal color. In some cases, an anchor coat layer is formed on the surface of the metal color film layer and then the printing layer is offset printed, and a transparent or matte PP resin film is attached to the surface of the printing layer, or The display of characters, graphics, etc. is printed together.

It is the model schematic which expanded and showed the formation process of the surface side of the decoration processed sheet which concerns on this invention. It is the expanded sectional view which showed typically the metal color processing sheet | seat which used the conventional PP sheet as the base material. It is the partial top view seen from the surface side of the Example which formed the watermark pattern with the decorative processing sheet which concerns on this invention. It is the schematic which shows an example of the clear file formed with the decoration processed sheet which concerns on this invention.

Next, a decorative processed sheet according to an embodiment of the present invention will be described with reference to the drawings while comparing with a conventional metal color PP sheet.
As shown in FIG. 3, the conventional metallic color PP sheet 1 is printed on a back surface 2 a of a PP sheet substrate 2 with monochromatic or multicolor ink such as letters, figures, patterns, etc., and the printed surface 3 has a metallic color. It is the structure which formed the silver film layer 4 for taking out by vapor deposition. The silver film layer 4 is solidly deposited on the entire printed surface 3 on the back surface. In this case, the silver film cannot be vapor-deposited in a dotted pattern according to the fine pattern, or the fine blank can be left behind, and the printed layer 3 on the back surface can be seen through from the front surface 2b side. However, quality such as color development is not always good.

  The decorative processed sheet 10 of the embodiment of the present invention illustrated in FIG. 1 is based on a transparent / translucent plastic film such as a PP sheet or a PET sheet, and the adhesive 12 is applied to the back surface of the substrate sheet 11. The foil material 13 exhibiting a metallic color is adhered. This foil forming surface can be made into a foil forming surface of any shape, and the part where the metal color is to be extracted and the part where the metal color is to be extracted by punching the foil are arbitrarily and selectively formed according to the pattern. Thus, for example, as described later with reference to FIG. 4, it is possible to easily perform processing such as forming a watermark pattern. In addition, in the processing operation for foiling, there is no need to worry about the generation of static electricity, and this point also has an effect different from that of the conventional metal color film deposition. After forming the foil, the surface protecting varnish 14 is applied to the entire surface of the foil forming surface, and the processing of the back surface is completed.

  Next, if processing on the surface side is described with reference to FIG. 1 and FIG. 2, ink printing of single color or multiple colors, for example, 5 to 7 colors, is performed on the surface of the base sheet 11 (FIG. 2B). . As printing in this case, known UV printing, offset printing, or the like is employed. A transparent embossing varnish 16 is applied to the surface of the ink print layer 15 as shown in FIG. In FIG. 2, the transparent embossing varnish 16 is hatched to distinguish it from other parts. In this case, although it can apply | coat uniformly to the whole surface of a printing surface, Preferably a desired printing site | part is partially selected and apply | coated corresponding to the pattern of the lower printing layer 15, and a pattern.

  After the application of the transparent embossing varnish 16, a transparent surface protecting varnish 17 is applied to the entire surface of the sheet as shown in FIG. Here, the embossing varnish 16 has no affinity for the surface protecting varnish 17, and the surface protecting varnish 17 is not repelled and adhered to the embossing varnish 16, and the surface protecting varnish 17 is applied. It becomes the form which the application part of the embossing varnish 16 exposed from the surface. Note that the thickness of the embossing varnish 16 is thicker than that of the surface protecting varnish 17 in comparison with the surface protecting varnish which is usually in the form of a thin film.

  The painted surface of the surface protecting varnish 17 has a smooth glossy surface, and the portion where the embossing varnish 16 is coated becomes a metallic surface of ink printing color that is slightly raised, and it is visually recognized as if the embossing was formed. The This is because the metallic color of the coating surface of the embossing varnish 16 is exposed to the metallic color ink of the printing layer 15 or the metallic color of the foil material attached to the back surface. Thus, in the decorative processed sheet 10 of the present invention, the flat and smooth glossy surface by the surface protecting varnish 17 and the metal color pseudo embossed surface by the embossing varnish 16 and the back foil material 13 are combined. .

  Since the back surface of the processed sheet 10 of the present invention is coated with the surface-protecting varnish 14 on the foil adhesion surface, it becomes a smooth metallic-colored glossy surface. Here, the foil material 13 on the foil adhering surface can be partially punched, and when viewed from the front side, this portion is visually recognized as a watermark pattern.

  FIG. 4 is a plan view partially showing an example of the sheet surface when the foil material is partially die cut. If the watermark pattern is formed by partial die cutting of the foil material, as shown in FIG. 4, after the ink printing on the front surface is performed, the partial die cutting 18 on the rear foil forming surface is performed. In this case, depending on the coating thickness of the printing ink, a die-cut watermark pattern (portion 18) appears on the ink printing surface 19 on the surface. However, after performing the die cutting 18 on the foil forming surface, if another ink printing is performed with a thick coating thickness so as to partially overlap the ink printing surface 19 with a small coating thickness, the ink printing surface 20 with this thick coating thickness. No stamped watermark appears in this part. In this way, even when the same die-cutting 18 is performed on the foil forming surface on the back surface, depending on the form of multi-color ink printing on the front surface, a portion where a watermark pattern appears and a portion where it does not appear can be generated. A variety of decorations can be obtained.

  In FIG. 4, a metal-colored colored surface by the foil material on the back surface appears in the ink printed portion denoted by reference numeral 19, and a watermark portion (reference numeral 18) by die cutting is exposed on the colored surface. When a white ink printed pattern (reference numeral 20) is partially applied to this surface with a thicker coating thickness, the watermark pattern on the back surface does not appear in the portion of the white ink printed pattern. In this way, any and various decorative sheets can be realized by combining the die cutting 18 of the foil material on the back surface and the ink printing form on the front surface side.

  FIG. 5 is a perspective view in the case where the clear file 21 is manufactured by the decorative processing sheet according to the present invention. The clear file 21 of this embodiment is also manufactured by folding and superimposing one side portion 21a of a rectangular sheet and bonding the lower edge 21b like a normal clear file. A colored foil attachment surface 22 is formed. On the surface of the quare file 21, a metallic colored ink printing surface 23 and an ink printing surface that does not become a metallic color, such as a white ink printing pattern 24, appear. The embossed varnish 16 (FIG. 2) is applied to the entire surface of the metallic colored ink printing surface 23 except for the white ink printed pattern 24, and finally the surface protecting varnish 17 (FIG. 2) is applied to the entire surface. As a result, a smooth surface protecting varnish remains only in the portion of the white ink printed pattern 24, and a metal color pseudo embossed surface is formed in the other portions. In this way, the decorative processed sheet according to the present invention can be obtained in various decorative processed sheets by combining the foil material on the back surface with the ink printed pattern on the surface, the embossing varnish and the surface protecting varnish. In the above-described embodiment, an example in which a clear file is manufactured using a decorative sheet has been described. However, the decorative sheet according to the present invention can be used for manufacturing various products such as decorative boxes, cards, advertising POPs, and postcards. Of course. In the embodiment according to the present invention, one surface and the other surface of the base sheet have been described by the terms of the front and back surfaces of the base sheet, but various articles are created by the decorative processed sheet of the present invention. In this case, which surface is used as the front side or the back side is arbitrarily selected according to the required decoration and visibility. Further, the method of fixing the foil material 13 is not limited to adhesion by an adhesive, and various other methods of fixing such as crimping, gluing, and sticking can be selected.

  As described above, the decorative processed sheet according to the present invention can selectively mix a portion exhibiting a metal color and a portion not exhibiting a metal color by punching a foil by using a foil material to exhibit a metal color. became. In addition, conventional metal-deposited films are prone to static electricity, and it took very skill to form a metal color surface by sticking the film. On the other hand, a clean metal color surface can be easily formed by fixing the foil material. can do. Moreover, if the embossing varnish 16 is applied, the fine uneven portions of the pattern can be easily exposed, and a clear printed surface can be obtained on the surface, giving a high-class feeling. Furthermore, the base material is composed of transparent and translucent sheets such as PP sheets and PET sheets, and is given a metallic color by fastening the foil material, so that clear files, packaging boxes for confectionery boxes, etc. It can be used as boxes, advertising POPs, various other cards, postcards, catalogs, posters, etc.
