Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard box for packaging an object to be packaged, such as an oil fan heater, and a printing method thereof.

[0002]

2. Description of the Related Art In recent years, devices such as oil fan heaters are often displayed as they are packaged at retail stores. Therefore, the illustration of the product is printed on the surface of the packaging cardboard box so that the customer can see the contents at a glance, and in the case of a product with multiple body colors in one model, By printing the product illustration on the surface of the packaging cardboard box in the same color as the body color of the product, it is possible to prevent the product from being traded in the wrong color and at the same time to improve the design of the packaging cardboard box. I am raising.

The conventional corrugated cardboard box for packaging described above is shown in FIG.
As shown in FIG. 4, the product illustration 3 of the product 2 to be packaged is printed on the front and rear surfaces of the packaging cardboard box 1. Then, as shown in FIG.
The overall image pattern a is printed with ink of the same or similar color as the body color of product 2, and the outer contour pattern a of the product is overprinted with black ink to create a three-dimensional effect.

[0004]

By the way, as described above, in the case of overprinting the overall image pattern A and the outline line pattern B, not only a plurality of printing plates for printing the product illustration 3 are required, but also However, the printing process is complicated, which is disadvantageous in terms of cost.

When the product illustration 3 is printed in a single color that is the same as or similar to the body color of the product 2, especially when the product body color is white, it is printed with a negative film created from a photograph of the product. When printing with a plate (negative type printing plate), the amount of ink attached to the surface of the corrugated paper is significantly reduced, so the exposed area of the corrugated paper in the product illustration 3 increases and the product illustration 3 becomes blurred. The power of expression was poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a corrugated cardboard box for packaging which enables reduction of the number of required printing plates and simplification of the printing process and is advantageous in terms of cost.

Another object of the present invention is to provide a method of printing a corrugated cardboard box for packaging, which is advantageous in terms of cost, rich in expressive power, and capable of producing a three-dimensional effect of the pattern on the package.

[0008]

The present invention is a structure in which a single-colored package pattern of a color that is the same as or similar to the body color of the package is printed on the surface, and another invention is This is a printing method in which a positive type printing plate is used to print a pattern of a packaged object on the surface of a corrugated cardboard with a single color ink having a color which is the same as or similar to the body color of the packaged object.

[0009]

In this way, since the pattern of the packaged object is expressed only by a single color that is the same as or close to the body color of the object to be packaged, and the overprinting of the outline pattern with black ink is omitted, Not only is it possible to prevent products from being traded in the wrong color, but it is also possible to reduce the number of printing plates and simplify the printing process.

Further, in the method for printing a corrugated cardboard box for packaging according to claim 2, a positive type printing plate is used to form a pattern on a package with a single color ink having a color which is the same as or approximate to the body color of the package. Printing on the surface of corrugated paper reduces the number of printing plates and simplifies the printing process.For example, even if the body color of the packaged item is white, the A sufficient amount of adhesion can be secured, and therefore, the exposed area of the corrugated cardboard cloth in the pattern to be packaged is reduced and the sharpness of the pattern to be packaged is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings of FIGS. 1 and 2, and the same parts as those of the prior art will be designated by the same reference numerals. In FIG. 1, 4 is a cardboard box for packaging 1.
The product illustrations 4 are printed on both front and back surfaces of the product. The product illustration 4 is printed in a single color that is the same as or close to the body color of the product 2.

When the body color of the product 2 is, for example, two colors of white (white) and gray (gray), the product illustration 4 is printed on the corrugated paper in accordance with the body color of the product 2. That is, when the body color of the product 2 is white, the product illustration 4 is white or a white-based ink close to the color.
When the body color of product 2 is gray, product illustration 4 is printed with gray or a gray-based ink that is similar to that color.
Is being printed.

Next, the printing method according to the present invention will be described. First, a positive type printing plate is made by using a positive film made by photographing the product 2. A photosensitive resin plate is generally used as a plate material for this printing plate. The positive type printing plate thus prepared is fixed to the outer circumference of the printing cylinder of a flexographic printing machine using a quick-drying liquid ink. Here, when a sheet-shaped cardboard is fed between the printing cylinder and the impression cylinder, a liquid ink of a single color which is the same as or close to the body color of the product 2 supplied to the positive type printing plate is applied to the surface of the corrugated paper. After the transfer, the product illustration 4 is printed on the surface of the corrugated paper.

At this time, in the printed product illustration 4, as shown in FIG. 2, the lightness and darkness of each part is represented by the change of the dot area per unit area. That is, the upper part in FIG. 2 is a part where the colored dots are dense and the color appears dark (dark), and the lower part is the part where the dots are scattered and the color appears light (bright). is there. Further, in FIG. 1, a region shaded with parallel hatching is a portion where the color appears dark, and a portion where there is a dot is a portion where the color appears light.

According to this embodiment, the cardboard box for packaging 1
Is printed with a single-colored product illustration 4 in the same or similar color as the body color of the product 2 on the front and back of the product, so that the customer can see the contents at a glance and the product can be displayed at the store as it is packaged. Even if you can enhance the display effect,
In the case of product 2 in which multiple body colors are prepared for one model, the body color of product 2 can be confirmed by the color of the printed product illustration 4, and it is possible to prevent the product from being sold by mistake. In addition to being able to do it, the product illustration 4 is expressed in only one color, and the overprinting of the outline pattern with black ink is omitted, eliminating the need for a plate for printing the outline pattern, thus reducing the number of plates. The printing process can be simplified, and the printing cost can be reduced.

Further, in the method according to the present embodiment, a positive type printing plate made by using a positive film is used, and the product 2 is put on the surface of the corrugated cardboard for making the corrugated cardboard box 1 for packaging.
Since the product illustration 4 is printed with a single color ink that is the same color as or similar to the body color of, the number of printing plates can be reduced and the printing process can be simplified, and the body color of the product 2 can be reduced. Even if the color is white, the amount of ink attached to the corrugated cardboard can be increased, so the exposed area of the corrugated cardboard in Product Illustration 4 is greatly reduced, and the outer line pattern is overprinted with black ink. Needless to say, the product illustration 4 does not appear blurry, the definition of the product illustration 4 is enhanced, and the three-dimensional effect can be sufficiently obtained.

[0017]

Since the cardboard box for packaging of the present invention is configured as described above, the contents can be seen at a glance, and the display effect can be sufficiently enhanced even in the as-packaged state.
It is possible to prevent products from being traded in the wrong color, and it is also possible to reduce the number of printing plates and simplify the printing process, thus reducing the printing cost.

In the method for printing a corrugated cardboard box for packaging according to claim 2, the exposed area of the corrugated cardboard cloth in the pattern to be packaged can be reduced, and the outer line pattern is not overprinted with black ink. In addition, the sharpness of the pattern of the packaged object can be enhanced, and the three-dimensional effect can be sufficiently produced, and beautiful printing can be performed while reducing the printing cost.
