（産業上の利用分野）
本発明は紙、フィルム等のグラビア輪転印刷方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a rotogravure printing method for paper, film, etc.
（従来の技術）
紙、フィルム等のグラビア輪転印刷では、被印刷物の帯
電、イン率（溶剤を含む）の帯電により。(Prior art) In rotogravure printing of paper, film, etc., the printing material is charged and the in-rate (including the solvent) is charged.

。Ink splatters called splatters can occur, which can detract from the aesthetic appearance of printed matter and become a problem. As a countermeasure to this problem, many methods have been tried to eliminate static electricity from the printing material, such as removing static electricity from the printing material before printing, removing static electricity from the surface of the printing material immediately after printing, or using conductive rubber for the impression roll.
（発明が解決しようとする問題点）
上記のような従来法は、被印刷物に対する除電効果はあ
るものの、インキに対する除電がなされていないため、
ヒゲを完全に防止できないという問題があった。(Problems to be Solved by the Invention) Although the conventional method described above has the effect of eliminating static electricity from the printing material, it does not eliminate static electricity from the ink.
There was a problem that beards could not be completely prevented.
本発明は被印刷物およびインキの除電を同時に行うこと
により印刷時のヒゲ発生を防ぐことを目的とするもので
ある。An object of the present invention is to prevent the occurrence of whiskers during printing by simultaneously removing static electricity from the printing material and ink.

ことができることを見出し本発明に到達した。(Means for Solving the Problems) In order to solve these problems, the inventors of the present invention have conducted intensive research and found that by installing a static eliminator on the printing surface side and removing static electricity from the printing material and the ink at the same time. The inventors have discovered that it is possible to prevent the formation of facial hair and have arrived at the present invention.

付近でかつ、被印刷物の印刷面側に除電装置を設置する
ことを特徴とする印刷方法を要旨とするものである。That is, the present invention is characterized in that when printing a piece of paper, film, etc. with a rotogravure printing press, a static eliminator is installed near the separation point between the impression roll and the printing material and on the printing surface side of the printing material. The gist is the printing method.

直径５ｍｍ以下の紐状物を用いることが好ましい。By providing the static eliminator near the separation point between the impression roll and the printing material and on the printing surface side, it is possible to eliminate static electricity from the printing material and the ink at the same time, and it is possible to obtain good printed matter without the occurrence of whiskers. In particular, it is preferable that the static eliminator be installed at a position within 3 cm from the printing material and within 5 cm from the peeling point in the printing material traveling direction. As static eliminators, there are commercially available mall-shaped ones, brush-shaped ones,
Any material, such as a cloth-like material, may be used, but considering workability since it is on the printing side, It is preferable to use a string-like material.

ンキを同時に除電できるため、容易にヒゲを防ぐことが
できる。(Function) In the present invention, by installing a static eliminator near the separation point between the impression roll and the printing material and on the printing surface side of the printing material, the ink immediately after printing on the printing material and the printing material can be simultaneously removed. Since static electricity can be removed, facial hair can be easily prevented.

も、ヒゲに対する効果が減少し、剥離点から被印刷物進
行方向に５ｃｍ以内とすることにより、ヒゲに対する効
果が大きいことがわかった。There are two reasons for this, according to research by the present inventors: After the ink is transferred to the printing substrate, the ink and the printing substrate are charged at the point where the impression roll and the printing substrate separate, and the ink and the printing substrate are charged in the vicinity of the separation point. It is possible that beards may occur. Through further research, we found that the installation location of the static eliminator has little effect on hairs before the separation point between the impression roll and the printed material, and that the effect on hair removal decreases even if it is far away from the separation point between the impression roll and the printed material. It has been found that the effect on whiskers is greater when the distance from the peeling point is within 5 cm in the direction of travel of the printed material.
さらに除電装置と被印刷物との距離は近いほど望ましい
が、除電装置や被印刷物がインキにより汚れる危険があ
る。本発明者らの研究によれば。Furthermore, although it is desirable that the distance between the static eliminator and the printing material be as short as possible, there is a risk that the static eliminator and the printing material may be stained with ink. According to the research of the present inventors.
被印刷物より３ｃｍ以内の位置に除電装置を設置すれば
ヒゲに対する効果が大きいことがわかった。It has been found that installing the static eliminator at a position within 3 cm from the printing material has a great effect on hairs.

り、不平等電界が形成されやすくなり。Although any static eliminator may be used, it is preferable to use a string-like material having an electrical resistance of 1 Ω·clI+ or less and having a diameter of 51III+ or less and having many fluffs on its surface. When the specific electrical resistance exceeds 1 Ω·cIll, the static elimination performance decreases significantly. Individual electrical resistance is lΩ・C
II+ or less and having a large number of fuzz on one surface makes it easy to form an unequal electric field.
自己放電開始電圧が低くなり、相手すなわち被印刷物お
よびインキに対する除電性能が良くなる。The self-discharge starting voltage is lowered, and the static elimination performance against the other party, that is, the printing material and the ink, is improved.

で作業性が良く好ましい。In addition, because of the need to reposition it at a specific position on the printing surface side, it is preferable to use a molded type, brush type, or cloth type.
It is preferable to use a string-like material with a diameter of mm or less because it is easier to load and remove, and the workability is better.
