Description

本願発明は、グラビア印刷に使用するシリンダーにおいて、版面を製版したシリンダーを印刷製品の製造仕様のものと合致するかを照合する方法に関する。 The present invention relates to a method for checking whether a cylinder used for gravure printing matches the production specifications of a printed product.

グラビア印刷においては、外周面に凹版面(セル)を製版したシリンダーを回転させ、このシリンダーへ印刷製品となるフィルムなどの原紙を圧接走行させて凹版面に保持したインキをフィルムなどの紙面へ吸着移行させる。 In gravure printing, a cylinder with an intaglio surface (cell) on its outer periphery is rotated, and base paper, such as a film that will become the printed product, is run against the cylinder under pressure, and the ink held on the intaglio surface is adsorbed onto the film or other paper surface. Migrate.

一つのグラビア印刷機には多数のシリンダーが使用され、また、印刷工場においては多数のグラビア印刷機が稼働している。そこで、製版されたシリンダーの選択間違いがないか、印刷対象となる印刷製品の製造仕様と照合する作業が不可欠となる。 A large number of cylinders are used in one gravure printing machine, and a large number of gravure printing machines are operated in a printing factory. Therefore, it is essential to check the manufacturing specifications of the printing product to be printed to make sure there are no errors in the selection of the cylinder that has been made.

前記の照合作業のために、従来はユニークなコードをQRコード(登録商標)、データマトリクス、POSなどで表示した識別ラベルをシリンダーの版カバーに添付し、版カバーに貼付した識別ラベルのコードをハンディスキャナーで読み取ることにより印刷製品の製造仕様中に登録された識別情報と照合していた。 For the above-mentioned verification process, conventionally, an identification label with a unique code displayed as a QR code (registered trademark), data matrix, POS, etc. was attached to the plate cover of the cylinder, and the code of the identification label affixed to the plate cover was used. By reading it with a handy scanner, it was compared with the identification information registered in the manufacturing specifications of the printed product.

また、識別ラベルに代えRFタグを用いる方法もとられていた。 Furthermore, a method of using an RF tag instead of an identification label has also been adopted.

一方、グラビア印刷用のシリンダーの管理方法としてシリンダーの端部やシャフトの外周面に識別表示を付することも提案されていた(特許文献1)。 On the other hand, as a method of managing cylinders for gravure printing, it has been proposed to attach identification marks to the ends of the cylinders and the outer peripheral surface of the shafts (Patent Document 1).

特開平9-216335号公報Japanese Patent Application Publication No. 9-216335

しかしながら、前記の、識別ラベルをグラビア印刷用のシリンダーの版カバーに貼付する方法は識別ラベルの貼り間違え、カバーの掛け間違えなどにより、照合作業を行っていたにも関わらず誤ったシリンダーで印刷される事故が稀に発生していた。 However, with the above-mentioned method of attaching the identification label to the plate cover of the cylinder for gravure printing, printing may occur with the wrong cylinder despite the verification work due to the identification label being attached incorrectly or the cover being attached incorrectly. Accidents occurred rarely.

また、RFIDを用いた照合方法においては、シリンダーが増えるにつれ新たにRFタグを購入する費用が発生する問題があった。 Further, in the verification method using RFID, there is a problem in that as the number of cylinders increases, the cost of purchasing new RF tags increases.

さらに、金属でできたグラビア印刷用のシリンダーへのRFタグを直接添付すると読み込みができない、シリンダー表面への添付では印刷時に邪魔になる、シリンダー端部ではインキに埋もれてしまうため剥がれるなどの問題を生じた。 Furthermore, if an RF tag is attached directly to a metal cylinder for gravure printing, it cannot be read, if attached to the surface of the cylinder, it becomes a hindrance during printing, and if attached to the cylinder end, it is buried in ink, causing problems such as peeling off. occured.

そのためにシリンダー内部にプラスチック製の台座を設けて設置するなどの方法が取られたが、検出感度が悪く、印刷時にシリンダー内部に入る溶剤、インキにより剥がれてしまうなどの問題が生じた。 For this purpose, methods such as installing a plastic pedestal inside the cylinder were taken, but the detection sensitivity was poor and problems such as the solvent and ink that entered the cylinder during printing caused it to peel off.

また、落版してシリンダー母材を再利用する場合にRFIDのデータを書き換え再添付しなければならないという手間も生じた。 Furthermore, when the cylinder base material is reused after the printing is removed, the RFID data must be rewritten and reattached, which is a hassle.

また、RFIDの場合タグの付け間違え、脱落というリスクの発生も懸念される。 Additionally, in the case of RFID, there is a risk of tags being attached incorrectly or falling off.

一方、特許文献1に記載の発明はシリンダー母材自体、すなわち、落版して再利用するシリンダー母材の識別手段であり、一つのシリンダー母材が印刷の都度、版面を製版して別のシリンダーになる版面を製版したシリンダーの識別手段とはなり得ない。 On the other hand, the invention described in Patent Document 1 is a means for identifying the cylinder base material itself, that is, the cylinder base material that is reused by dropping the plate. It cannot be used as a means of identifying the cylinder from which the plate that will become the cylinder was made.

本願発明は前記の問題を解消したグラビア印刷用のシリンダーの版照合方法を提供することを目的として創作されたものである。 The present invention was created for the purpose of providing a plate verification method for gravure printing cylinders that solves the above-mentioned problems.

すなわち、本願発明のグラビア印刷用のシリンダーの版照合方法は、圧胴の端部側方にインキはね防止用のカバーを設けたグラビア印刷機において、グラビア印刷用のシリンダーの端部寄りにして圧胴の圧接個所より外れ、さらにインキはね防止用のカバーにより覆われる領域に、ユニークなコードを刻印によりダイレクトマーキングし、上記コードを識別情報として、ダイレクトマーキングスキャン性能を有するハンディスキャナー、ハンディターミナルで読み取ることにより、読み取った識別情報を印刷製品の製造仕様中に登録された識別情報と照合することを特徴とする。 In other words, the plate verification method for a cylinder for gravure printing according to the present invention uses a gravure printing machine in which a cover for preventing ink splashing is provided on the side of the end of the impression cylinder. A unique code is directly marked by engraving in an area that is removed from the press contact point of the impression cylinder and is covered by a cover to prevent ink splashing, and the above code is used as identification information to create a handy scanner and a handy terminal that have direct marking scanning performance. The feature is that the read identification information is compared with the identification information registered in the manufacturing specifications of the printed product.

また、請求項2記載の発明は前記のグラビア印刷用のシリンダーの版照合方法において、ユニークなコードはQRコード(登録商標)、データマトリクス、POS、文字列などであることを特徴とする。 Further, the invention according to claim 2 is characterized in that the unique code is a QR code (registered trademark), a data matrix, a POS, a character string, etc. in the plate verification method for a cylinder for gravure printing.

また、請求項3記載の発明は前記のグラビア印刷用のシリンダーの版照合方法において、刻印するコードを印刷用のシリンダーの端部から30mm以下の領域に設けることを特徴とする。 Further, the invention as set forth in claim 3 is characterized in that, in the above-mentioned plate verification method for a cylinder for gravure printing, the code to be engraved is provided in an area of 30 mm or less from the end of the cylinder for printing.

本願発明のグラビア印刷用のシリンダーの版照合方法によれば、シリンダーにユニークなコードをQRコード(登録商標)、データマトリクス、POS、文字列などとして刻印によりダイレクトマーキングし、上記コードを識別情報として、ダイレクトマーキングスキャン性能を有するハンディスキャナー、ハンディターミナルで読み取るので、これまでの識別方法として実施されてきた版カバー、RFIDといった、シリンダーカバーやシリンダーに識別表示できるものを貼り付けるといった作業により発生する貼り間違えを防止することが可能になる。 According to the plate verification method for gravure printing cylinders of the present invention, a unique code is directly marked on the cylinder as a QR code (registered trademark), data matrix, POS, character string, etc., and the code is used as identification information. , a handy scanner with direct marking scanning performance, and a handy terminal to read the data, so it is possible to avoid pasting of identification marks on cylinder covers and cylinders, such as plate covers and RFID, which have been used as identification methods up until now. It becomes possible to prevent mistakes.

一方、コードが配置される位置は、グラビア印刷用のシリンダーの端部寄りにして圧胴の圧接個所より外れているので圧胴にニップされず版面からインキが転写されない。また、通常その付近にはインキが飛散することを防止するためにインキはね防止用のカバーが設置されるのでインキはねのリスクもない。 On the other hand, the cord is placed near the end of the gravure printing cylinder and away from the pressure contact area of the impression cylinder, so it is not nipped by the impression cylinder and no ink is transferred from the plate surface. Further, there is no risk of ink splashing because an ink splash prevention cover is usually installed in the vicinity to prevent ink from scattering.

本願発明のグラビア印刷用のシリンダーの版照合方法に使用されるシリンダーの平面図。FIG. 2 is a plan view of a cylinder used in the gravure printing cylinder plate matching method of the present invention.

図1は本願発明のグラビア印刷用のシリンダーの版照合方法に使用されるシリンダーおよび圧胴を模式的に表した平面図である。図中符号1は公知のグラビア印刷用のシリンダーであり、表面にインキを保持するための凹版面2が製版される。また、図中符号7は圧胴である。 FIG. 1 is a plan view schematically showing a cylinder and an impression cylinder used in the gravure printing cylinder plate verification method of the present invention. Reference numeral 1 in the figure is a cylinder for known gravure printing, on which an intaglio surface 2 for holding ink is made. Further, the reference numeral 7 in the figure is an impression cylinder.

前記のシリンダー1において、コード6はグラビア印刷用のシリンダーの端部寄りにして圧胴の圧接個所3より外れた領域5に刻印によりダイレクトマーキングされる。また、この個所はインキはね防止用のカバー4により覆われる領域でもある。 In the cylinder 1 described above, the code 6 is directly marked by engraving in a region 5 near the end of the cylinder for gravure printing and away from the pressure contact point 3 of the impression cylinder. Further, this area is also covered by the cover 4 for preventing ink splashing.

なお、シリンダー、圧胴、被印刷物の関係において、1200mm幅のシリンダーに対して、圧胴はマイナス60mm幅、被印刷物幅はマイナス40mm幅が最大となる。この場合、圧胴はマイナス60mm幅は左右均等であり、片側30mmは圧胴にニップされず版面からインキが転写されない。 Regarding the relationship between the cylinder, impression cylinder, and printing material, for a cylinder with a width of 1200 mm, the maximum width of the impression cylinder is minus 60 mm, and the maximum width of the printing material is minus 40 mm. In this case, the width of the impression cylinder is equal to -60 mm on both sides, and 30 mm on one side is not nipped by the impression cylinder and no ink is transferred from the plate surface.

圧胴の幅は被印刷物の幅に合わせて変えながら加工する場合があるが、シリンダー端部から30mm以内であればどの圧胴幅であってもニップされインキが転写されることがない。 The width of the impression cylinder may be changed in accordance with the width of the printing material during processing, but as long as it is within 30 mm from the end of the cylinder, nip will not occur and ink will not be transferred regardless of the width of the impression cylinder.

コード6はユニークなコードであり、QRコード(登録商標)、データマトリクス、POS、文字列などとして刻印によりダイレクトマーキングされる。 Code 6 is a unique code and is directly marked by engraving as a QR code (registered trademark), data matrix, POS, character string, etc.

グラビア印刷用のシリンダーは曲面、鏡面であり刻印されたコードをハンディスキャナーで読み込むことができなかったが、近年ダイレクトマーキング用のハンディスキャナー、ハンディターミナルが登場し、読み込み精度が向上したことで読み込みが可能となった。 Cylinders for gravure printing have curved or mirrored surfaces, making it impossible for handheld scanners to read the engraved codes. However, in recent years, handheld scanners and handheld terminals for direct marking have appeared, and reading accuracy has improved, making reading easier. It has become possible.

以上のグラビア印刷用のシリンダーはコード6からハンディスキャナー、ハンディターミナルで識別情報を読み取ることができるので、それを印刷製品の製造仕様中に登録された識別情報と照合することにより版照合が実施される。 The identification information of the cylinders for gravure printing mentioned above can be read from code 6 using a handy scanner or a handy terminal, so plate verification is performed by comparing it with the identification information registered in the manufacturing specifications of the printed product.
