Description

  The present invention relates to a printed material partially printed with a metallic glossy surface, and more particularly to a printed material that is easy to handle without overcoating the metallic glossy surface.

  Conventionally, it has been known that printing ink containing aluminum powder is used to display metallic gloss on the surface of packaging containers and other articles other than metal ones to enhance the decorativeness. (For example, refer to Patent Document 1). In this case, the printing surface containing aluminum powder and printed with colorless printing ink exhibits a so-called silver color. Usually, the printing ink containing aluminum powder is often used in which scaly aluminum powder is mainly mixed in the printing ink, and the color tone of the metallic luster differs depending on the mixing amount of the aluminum powder.

Japanese Patent Application No. 11-78204

  By the way, conventionally, in a printed matter that expresses a metallic luster partially using an aluminum powder-containing printing ink by offset printing or the like, the portion that holds the metallic luster depends on the state of the printed matter. Compared with the portion printed with printing ink, there is a problem that when the metallic gloss portion rubs against other objects, scratches are generated and the commercial value is lowered. In other words, since the aluminum powder contained in the ink is attached to the surface of the portion printed with the aluminum powder-containing printing ink in a floating state, the surface appears intensely unevenly microscopically, When rubbed, the aluminum powder is peeled off or displaced and polarized, and the rubbing part becomes black and gives a sense of incongruity.

  As a measure to avoid such a phenomenon, in order to prevent the occurrence of scratches on the metallic glossy surface, the aluminum powder on the metallic glossy surface printed with a clear layer overcoated on the surface directly adheres to other objects. Avoid contact. However, when such an overcoat layer is formed, there is a problem that the metallic color is inevitably reduced and the decorativeness is lowered. Further, if the amount of aluminum powder to be contained is reduced to suppress the exposure of the powder to the surface after printing, the metal color revealing ability is reduced and the decorativeness is lowered, which is not preferable.

  Therefore, if the printing surface (metal gloss forming surface) with aluminum powder-containing printing ink is exposed as it is with emphasis on decorativeness as described above, for example, in the printing process, printed sheets that are sequentially printed If the printing surface is rubbed when superimposing, the above-described scratches are likely to occur. In addition, when the printed sheet is processed to form a packaging container, for example, or in the distribution stage until the product is packaged in the product of the obtained packaging container and delivered to the consumer's hand In addition, there is a problem that it is unavoidable that the metal gloss forming surface is scratched when it is rubbed with other objects, and the commercial value is lowered.

  The present invention has been made to solve such a problem, and forms a difference in level so that the metallic gloss forming surface is different from other printing surfaces, and rubs with other materials during handling after printing. It is an object of the present invention to provide a printed material that has been subjected to metallic gloss printing in a part that does not impair decorativeness.

In order to achieve the above-mentioned object, a printed matter in which a portion of the present invention is subjected to metallic gloss printing is:
In the offset printed matter of a paperboard displaying a metallic gloss part on a part of the printing surface, the metallic gloss part is formed in a concave surface (first invention).

  In the above invention, the metallic luster portion may be coated with a transparent film layer at the peripheral edge (second invention).

  In the invention, the metallic gloss portion is extended to a three-dimensional edge by processing the printed matter, and the metallic gloss printed portion edge portion is preferably coated with a transparent film layer (first 3 invention).

  According to the present invention, when the metallic gloss portion printed on a part of the printing surface is formed in a concave surface from the other adjacent printing surfaces, when handling this printed material after printing, for example, the printed materials may overlap each other. When the sheet is moved laterally, rubbing is avoided because the metallic luster portion is concave with respect to the entire printing surface. Accordingly, it is possible to prevent the metallic glossy surface from being scratched by being rubbed. As a result, the occurrence of scratches can be avoided, so that a metallic revealing portion can be provided without overcoating the metallic gloss forming surface, and an effect is obtained that a printed matter with high decorativeness can be obtained.

  Further, in the above invention, when providing a metallic gloss part on a part of the printing surface, by covering the peripheral part with a transparent film layer, it is possible to prevent the edge of the metallic gloss part from being rubbed and peeled off. Can be maintained. In particular, when forming a packaging container or the like using a sheet printed with this metallic gloss portion, if the metallic gloss portion is located at the bent edge of the container, the frequency of rubbing during handling increases, but the edge portion becomes the edge portion. If a transparent film layer is formed at a location, the metal powder-containing ink layer can be protected against rubbing, and the product value can be prevented from being lowered.

  In addition, about the paperboard which comprises the printed matter in this invention, it shall generically include a paperboard and decorative cardboard.

  Next, a specific embodiment of a printed matter in which a portion of the present invention is subjected to metallic gloss printing will be described with reference to the drawings. In addition, as this embodiment, the bag-shaped container by which the surface is printed is demonstrated.

  1 is an overall perspective view of the bag-like container of the present embodiment, FIG. 2 is an enlarged cross-sectional view of part A in FIG. 1, and FIG. 3 is an enlarged cross-sectional view taken along line BB in FIG. FIG. 4 is a view showing a part of the printed sheet before processing the container.

  The bag-like container 1 of this embodiment (printed material; hereinafter simply referred to as the container 1 for convenience of explanation) is formed using paperboard. The container 1 wraps a sheet (product) cut into a predetermined size, and has a main body 2 formed in a vertically long dimension that can store (wrap) the sheet, and one side (upward) in the vertically long direction. ) And the lid piece 3 for closing the opening provided in the case. Moreover, the main-body part 2 is not provided with a gusset, but has a closed shape. The lid piece 3 has a function of allowing the product to be sealed after being accommodated in the main body 2 and closing the lid after taking out the product to facilitate storage. For this purpose, the lid piece 3 is provided with a zipper 4 for opening after packaging. In the figure, reference numeral 3 'denotes a cut-off portion after opening, and 7 denotes a hanging hole.

  The container 1 is provided with printing 5 on both the front and back surfaces, and a metallic gloss printing portion (metal gloss portion 6) is attached to a part of the surface of the main body 2. On the front and back surfaces including the metallic luster portion 6, characters / trademarks (not shown) related to the merchandise and designs or images that appeal the merchandise are printed, and a design that enhances the decorativeness as a whole is applied. And the printing performed on both front and back surfaces of the container 1 is performed by offset printing.

  The metallic gloss portion 6 is provided with a required design over the entire width in the width direction of the container 1 and is printed with printing ink containing metal powder (for example, aluminum powder). And the metallic luster part 6 surrounds the peripheral part 6a according to the design, and is formed in the concave surface a little lower than the adjacent part 5a. The concave surface portion (metallic glossy portion 6) is formed to have a step of, for example, 0.1 to 0.2 mm from the other outer surface.

  As illustrated in FIG. 2, the metallic gloss portion 6 is formed by applying a metallic gloss layer 10 made of the metal powder-containing printing ink on the surface of a paperboard (for example, a decorative sheet) 11 constituting the container 1. A transparent coating layer 13 is laminated on the upper side of the metallic luster layer 10 with an appropriate width at the boundary with the layer 12 of the printing ink. Further, the transparent film layer 13 having a width wider than the boundary portion (peripheral edge portion 6a of the metallic luster portion 6), for example, a width of about 5 mm, is laminated on the surface side at the portions that become both end edges 2 'and 2' of the main body 2. ing.

  The container 1 printed with a part of the metallic gloss portion 6 formed in this way is used in the production of the container 1 by using a material sheet 11 (for example, a decorative sheet) made of paperboard of a required size. With an offset printer, it is printed. In addition, about this offset printing, it prints as plate making by a well-known means. Moreover, as said metal powder containing printing ink, the aluminum powder containing printing ink is used according to the color tone of the metallic luster part 6, and it is set as the printing surface which exhibits a silver color. For example, when finishing a metallic glossy surface exhibiting a gold color, an ink using bronze powder as a contained pigment or a printing ink containing aluminum powder colored with a dye or pigment is used.

  The metallic glossy portion 6 printed with such a metal powder-containing printing ink is a punching die (not shown; the same applies hereinafter) in a punching process in which the sheet S that has been offset printed as shown in FIG. Thus, simultaneously with the punching of the printed sheet S, the metallic gloss portion 6 is pressed into a concave surface by a pressing die attached to the punching die. In this punching process, the outer shape is punched and formed with a punching blade (represented by a cutout outer contour line c), and fold lines d to f ′ (represented by two-dot chain lines) are formed at the bent portion.

  The blank of the container 1 obtained in the punching step is a crease line f at the connecting portion between the front surface and the back surface of the main body 2 and a double margin portion 8 for closing the front and back surfaces in a bag shape in the next bag making step. The respective parts are bent at 8 crease lines e and e, and are pasted on the paste margin parts 8 and 8 so that both front and back surfaces are formed in a bag shape.

  In the above-described processing step, the metallic gloss portion 6 is formed to have a lower surface than the other printing portions 5, so that it does not directly contact the transport surface of the processing machine when moving and does not generate scratches. can do. In addition, since the metallic glossy surface (metallic glossy portion 6) is a concave surface even when the products (containers 1) rub against each other even when stacked for transportation after bag making, the occurrence of scratches is prevented. can do.

  Since the container 1 obtained in this way can be handled without rubbing the metallic luster portion 6 as described above, after the package is contained and packaged, it is distributed as a product and reaches the consumer's hand, as described above. The metallic luster applied to the metal can be protected without overcoating, and the decorative effect can be enhanced in combination with the design displayed on the other printed surface.

  Further, in the container 1 of this embodiment, the metallic luster portion 6 is provided up to both end edge portions 2 ′ and 2 ′ of the main body portion 2. Accordingly, the edge 2 'of the main body 2 has a metal gloss forming surface (metal gloss part 6) bent, but the transparent film layer 13 is formed on the metal gloss part 6 in the part. Even if there is a subsequent contact with other objects arranged in the folding operation, the metal powder contained in the ink is covered by the transparent film layer 13, so that the metal color is maintained without being peeled off by an external force (see FIG. 3). Moreover, since the protection part by this transparent membrane | film | coat layer 13 is stopped by the very few part, the glossy color which the metallic luster part 6 has is not impaired.

  The metallic gloss portion 6 is covered with the transparent film layer 13 along the peripheral edge portion 6a, so that when the metallic gloss portion 6 performed at the time of blanking molding of the blank is pressed into a concave surface, a material is used. The sheet 11 can be processed without damaging the printed surface by preventing the metallic glossy portion 6 printed with the metal powder-containing printing ink from peeling off. In addition, it is possible to prevent the metal glossy surface from being peeled off by an external force after commercialization, and the decorativeness is not hindered.

  In the above embodiment, the bag-like container has been described. However, even when a metallic gloss portion is provided on the surface of a box-shaped packaging container (not shown), the metallic gloss portion is as described above. If is made concave, the same effect as described above can be obtained.

  Further, as shown in an enlarged cross-sectional view showing the main part of another embodiment in FIG. 5, when a normal printed portion 5 </ b> A is interposed in an island shape in the area of the metallic gloss portion 6, The printed part 5A (island-like part) may not be concave, but only the metallic luster part 6 may be concave. When forming in this way, when the container 1 is formed into a blank (at the time of punching), a concave mold for forming the concave surface is used so that only the metallic luster portion 5 is convex. Further, in the case where the island-like part is exposed in the area of the metallic glossy portion 6 described above, for example, the island-like part with a different metallic gloss, the island-like part is covered with a transparent film layer. It is preferable to leave. In this way, even if the island-shaped part touches other objects or is rubbed by an external force, it does not cause any trouble. In addition, when such pressing is used in combination, the island-like portion is three-dimensionally revealed and the design effect can be enhanced.

  As described above, according to the gist of the present invention, it is possible to provide a packaging container with improved decoration by adapting to various containers having a printing surface that effectively reveals metallic luster. Of course, it can be said that even a lithographic article is effective in adapting to a printed matter prepared using a paperboard or a composite sheet material (for example, a corrugated cardboard sheet having a decorative surface).
