Abstract

PROBLEM TO BE SOLVED: To provide a varnish printing method to finish an area other than a logo printed section (a white base section) in a manner to have a specified thickness, and make only the logo printed section thicker, and increase the gloss degree, and at the same time, make the logo printed section outstanding, which has been repeated a plurality of times, by one printing by one plate. SOLUTION: This varnish printing is applied for the surface glossiness and the protection of the printed surface for the logo printed section which is printed on one surface of a box or the like, and the white base section (a pattern or the like). In such a varnish printing, a varnish-applied amount is partially made thicker by one printing only at the logo-printed section of the printed surface. For this printing method, the varnish is applied on the white base section other than the logo printed section by using a gravure plate of 80 lines/inch, and on the logo printed section by using a gravure plate of 70 lines/inch or 60 lines/ inch.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of printing varnish in which the amount of transparent varnish applied on a logo printing portion such as a detergent box is increased so that the logo printing portion is three-dimensional and the surface glossiness is improved.

[0002]

2. Description of the Related Art Conventionally, when printing a box for storing a detergent or the like, a solid printing is applied to the entire surface, and a pattern is partially formed, and a logo printing portion such as a large character is used to make a product name stand out, and furthermore, surface protection. A transparent or translucent varnish printing layer is applied to obtain a layer and surface gloss. Conventionally, FIG.
As shown in FIG. 1, the surface is applied to one side of a detergent box or the like to give a surface gloss to the white background portions (printed portions such as patterns) 12 and 12, the logo printed portion 11 or the like, or to protect the printed portions such as patterns and logos. In printing the varnish layer 15, the whole is 80 l / inch.
The varnish printing was performed uniformly on the printing surface using a gravure plate engraved to a depth of. However, the glossiness and film thickness required to make the logo printed portion 11 particularly conspicuous were not obtained by one varnish printing. In other words, the current situation is that a plurality of times of varnish printing is usually performed in a single transparent varnish printing since a desired film thickness and glossiness as a desired protective layer cannot be obtained. In particular, in order to increase the surface gloss so that it stands out on the logo printing area, the varnish printing is repeated several times using a special gravure plate for the logo printing area to increase the film thickness and at the same time Was raised.

[0003]

However, even in the case of varnish printing only on the logo printing portion, varnish printing needs to be repeated twice or more including other portions, and there is a problem in time and cost. Therefore, the present invention is to increase the glossiness by making the varnish printing, which has been repeated several times, one time printing with one plate, by setting the thickness except for the logo printing part (white background part) to a predetermined thickness, and by embossing only the logo printing part. And a method of printing a varnish to make it stand out.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a varnish applied to a logo printed portion and a white background (a pattern, etc.) printed on one side of a box or the like to protect the surface gloss and the printed surface. In a printing method, a varnish printing method is provided, in which the varnish application amount is partially increased by printing once only on a logo printing portion of the printing surface.

[0005] Further, a white background portion other than the logo printed portion is 80
Line / inch, 70 lines / inch or 6 on logo print
It is characterized by being applied by using a gravure plate of 0 lines / inch.

[0006] Further, by the transparent varnish printing using the gravure plate, the surface gloss (light received by reflection at 60 degrees) becomes 30 to 60% in a white background portion and 70 to 90% in a logo printing portion. Things.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to varnish printing for imparting surface gloss to a pattern or the like printed on one side of a box or the like, or for protecting a pattern. A printing method characterized in that the varnish application amount is partially thickened by a single printing using a gravure plate, and a predetermined thickness is applied to portions other than the logo printed portion (white background portion), whereby the logo is printed. The glossiness of the surface of the portion is increased, so that the portion can be visually recognized three-dimensionally and becomes noticeable.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings.

FIG. 1 is an explanatory view showing a printed material according to an embodiment of the present invention, in which a varnish printing layer is thickened only on a logo printing portion by one varnish printing. As shown in FIG. 1, for example, a predetermined solid printing, a white background portion 12 such as a pattern is provided on a base material 10 made of cardboard or the like used for a decorative box of a detergent or the like, and a product name or the like of a large character is provided at a predetermined position. It is composed of a printed logo printing section 11 and further provided with a transparent or translucent varnish printing layer 15 on the entire surface. In particular, according to the varnish printing method of the present invention, by engraving the gravure plate with different depths and the like, the varnish amount is applied only on the logo printing portion 11 in one varnish printing, so that the glossiness increases. The logo printing part is three-dimensionally represented.

First, the entire gravure plate is engraved to a depth of 80 lines / inch using a printing plate engraving machine or the like, and the corresponding plate surface on the logo printing section 11 is engraved at 70 lines / inc.
By performing varnish printing using a printing plate engraved at a depth of h or 60 lines / inch, a varnish layer 15 in which the varnish application amount was increased only on the logo printed portion 11 was obtained. In addition, a predetermined film thickness was obtained also in the white background portions 12 other than the logo printed portion.

The glossiness of the varnish layer after drying was measured. As a result, a glossiness of 30 to 60% was obtained in the white background portions 12 and 12, and a glossiness of 70 to 90% was obtained in the logo printed portion 11, giving a three-dimensional appearance. Reproduction became possible. In addition, glossiness is JIS Z
It was measured according to the 8741 method (60-degree specular gloss).

In the present invention, 70 l / inch or 60 l / inch is used in the same manner as the logo of the logo printing section.
There is no difference in glossiness and the like between the case of engraving to the depth of the varnish and the case of varnish printing using the gravure plate engraved on the entire logo printing portion as described above.

[0013]

As described above, the present invention has the following effects. That is, conventionally, a varnish layer had to be provided on the entire printing portion by the first varnish printing using the second gravure plate, and further applied on the logo printing portion by the second varnish printing. By engraving the plate twice, a varnish layer having a thick embossed portion on the logo printing portion can be obtained by one printing. As a result, the glossiness on the logo printed portion is increased, and a three-dimensional effect is produced in the logo printed portion, so that the entire logo becomes conspicuous, and various excellent effects such as an improvement in design can be obtained.
