Description

[規則26に基づく補充 12.06.2015]　印刷機および印刷物の製造方法[Replenishment based on Rule 26 12.06.2015] Printing machine and printed matter manufacturing method
　本発明は、印刷の技術分野に関する。特に、インクジェット印字装置を付加したグラビア印刷機等の輪転印刷機を有する印刷機および印刷方法に関する。 The present invention relates to the technical field of printing. In particular, the present invention relates to a printing machine having a rotary printing machine such as a gravure printing machine to which an inkjet printing apparatus is added and a printing method.
　多色印刷機等においては、複数色のインキを印刷対象物の同一領域に１色毎に重ねて印刷しており、色ずれを防止するためには各色の印刷材料どうしを正確に位置合わせして印刷する必要がある。それゆえ、各色の印刷位置を正確に合わせることは、印刷物の品質上極めて重要である。この印刷位置を合わせることを「見当合せ」という。 In multicolor printers, etc., multiple colors of ink are printed on the same area of the printing object for each color, and in order to prevent color misregistration, the printing materials for each color are accurately aligned. Need to print. Therefore, it is extremely important for the quality of the printed matter to accurately match the printing positions of the respective colors. Matching the printing positions is called “registering”.
　印刷機において見当合せを行う方法は、印刷対象物の印刷領域外の余白において印刷された見当マークを検出する方法がある。この方法は、印刷対象物に印刷された見当マークを見当マーク検出センサによって検出し、見当マークどうしの相対的な位置関係から各版胴による印刷位置の誤差を検出し、この誤差を補正することで各色間の見当合せを行うものである。 As a method of performing registration in a printing press, there is a method of detecting a registration mark printed in a margin outside a printing area of a printing object. In this method, a registration mark printed on a printing object is detected by a registration mark detection sensor, an error in the printing position by each plate cylinder is detected from the relative positional relationship between the registration marks, and this error is corrected. The registration between each color is performed.
　しかしながら、前色ユニットの見当マークを基準にして後色ユニットの見当マークを順次合わせていく方式であるため、第１印刷ユニットが薄色の印刷材料であると、見当マーク検出センサでの検出が不安定化し、高精度な印刷位置合わせを行えないという問題があった。 However, since the registration mark of the rear color unit is sequentially aligned based on the registration mark of the front color unit, the registration mark detection sensor detects that the first printing unit is a light color printing material. There has been a problem that the printing position alignment cannot be performed with high accuracy.
　上記課題を解決するために、印刷対象物に絵柄等の実際に印刷を行う印刷ユニットの上流側の第１印刷ユニットに、見当マークのみを印刷するための版をグラビアシリンダーに装着して印刷領域外の余白に見当マークを印刷する方法がある。 In order to solve the above-mentioned problem, a printing area for printing only a registration mark is mounted on a first printing unit upstream of a printing unit that actually prints a pattern or the like on a printing object. There is a method of printing a register mark in the outer margin.
　この印刷方法によれば、第１印刷ユニットが薄色の印刷材料であっても、先行して印刷対象物に印刷されていた見当マークを基準として、各色間の高精度な印刷位置合わせを行うことができる。 According to this printing method, even if the first printing unit is a light-colored printing material, high-precision printing alignment between each color is performed with reference to the register mark that has been printed on the printing object in advance. be able to.
　一方、特許文献１には、グラビア印刷機と、印字内容を電子情報として入力可能なインクジェット方式のデジタルプリンタをインライン形式で設けた印刷装置で印刷及び印字をインラインで連続して行うことを特徴とする印刷方法が提案されている。 On the other hand, Patent Document 1 is characterized in that printing and printing are continuously performed inline with a gravure printing machine and a printing apparatus provided with an inkjet digital printer capable of inputting print contents as electronic information in an inline format. A printing method has been proposed.

There is a problem that the work of replacing the plate is excessive and complicated.
　また、特許文献１の印刷方法では、同一図柄をグラビア印刷機で印刷し、ロット番号等の追加情報をインクジェット方式のデジタルプリンタで印字する印刷方法については開示されているものの、見当合せの課題については解決されていない。 In addition, the printing method disclosed in Patent Document 1 discloses a printing method in which the same pattern is printed by a gravure printing machine and additional information such as a lot number is printed by an ink jet digital printer. Is not solved.

Of these, 15a is a registration mark detection sensor, 14a is a compensator roller, 16 is a compensator drive motor for operating the compensator roller 14a, and 17 is a plate cylinder 11a, 11b, and 11c moved in the width direction of the plate cylinder, and the width of the plate cylinder A side motor 30 for adjusting the position in the direction is a register control device.
　なお、見当合わせ装置の構成は、第２のグラビア印刷ユニット１０ｂ、および、第３のグラビア印刷ユニット１０ｃにおいても略同一の構成となる。 Note that the configuration of the registration device is substantially the same in the second gravure printing unit 10b and the third gravure printing unit 10c.
（見当マーク検出センサ）
　図１に示すように、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃは、版胴１１ａ、１１ｂ、１１ｃの下流側に配置された、見当マーク検出センサ１５ａ、１５ｂ、１５ｃを含む。 (Register mark detection sensor)
As shown in FIG. 1, each gravure printing unit 10a, 10b, 10c includes registration mark detection sensors 15a, 15b, 15c arranged on the downstream side of the plate cylinders 11a, 11b, 11c.
　見当マーク検出センサ１５ａ、１５ｂ、１５ｃは、図３に示すように、印刷対象物Ｗに付けられた基準見当マーク７および見当マーク８ａ、８ｂ、８ｃを検出するためのセンサである。 The registration mark detection sensors 15a, 15b, and 15c are sensors for detecting the reference registration mark 7 and the registration marks 8a, 8b, and 8c attached to the print object W as shown in FIG.
　ここで、見当マーク検出センサ１５ａは、印刷対象物Ｗ上の基準見当マーク７および第１の見当マーク８ａを検出し、見当マーク検出センサ１５ｂは、印刷対象物Ｗ上の基準見当マーク７および第２の見当マーク８ｂを検出し、見当マーク検出センサ１５ｃは、印刷対象物Ｗ上の基準見当マーク７および第３の見当マーク８ｃを検出するようになっている。 Here, the registration mark detection sensor 15a detects the reference registration mark 7 and the first registration mark 8a on the print object W, and the registration mark detection sensor 15b detects the reference registration mark 7 and the first registration mark 8a on the print object W. The second registration mark 8b is detected, and the registration mark detection sensor 15c detects the reference registration mark 7 and the third registration mark 8c on the print object W.
　また、見当マーク検出センサ１５ｂは、印刷対象物Ｗ上の第１の見当マーク８ａおよび第２の見当マーク８ｂを検出し、見当マーク検出センサ１５ｃは、印刷対象物Ｗ上の第２の見当マーク８ｂおよび第３の見当マーク８ｃを検出するようにしてもよい。 The register mark detection sensor 15b detects the first register mark 8a and the second register mark 8b on the print object W, and the register mark detection sensor 15c detects the second register mark on the print object W. You may make it detect 8b and the 3rd registration mark 8c.
　なお、通常、グラビア印刷の見当ずれの限度は０．５ｍｍ未満であるので、見当マーク検出センサ１５ａ、１５ｂ、１５ｃの精度（検知能力）は０．１ｍｍ～０．２ｍｍに設定されている。 In addition, since the limit of misregistration in gravure printing is usually less than 0.5 mm, the accuracy (detection ability) of the registration mark detection sensors 15a, 15b, and 15c is set to 0.1 mm to 0.2 mm.
　更に、損紙を減らすために、印字ユニット４０ａにおいて、インクジェット印字装置４０の下流側に見当マーク検出センサ１５ｉを配置してもよい。 Further, a register mark detection sensor 15i may be arranged on the downstream side of the ink jet printing apparatus 40 in the printing unit 40a in order to reduce waste paper.
　ここで、見当マーク検出センサ１５ｉは、印刷対象物Ｗ上の基準見当マーク７を検出するようになっている。そして、検出された基準見当マーク７の印字位置について、制御装置にて、予め設定されている基準点に対する位置座標からの流れ方向と幅方向の印字位置のずれを認識できるようになっている。 Here, the registration mark detection sensor 15i detects the reference registration mark 7 on the print object W. With respect to the detected print position of the reference registration mark 7, the control device can recognize the deviation between the print position in the flow direction and the width direction from the position coordinates with respect to the preset reference point.
　見当マーク検出センサ１５ａ、１５ｂ、１５ｃ、１５ｉの構成は、ＬＥＤ等の発光素子と、印刷対象物Ｗに対して発光素子と同じ側に設けられ、発光素子から発せられた後、印刷対象物Ｗより反射した光を受ける受光素子とを有している。 The registration mark detection sensors 15a, 15b, 15c, and 15i are provided on the same side as the light emitting element with respect to the light emitting element such as an LED and the print target W, and after being emitted from the light emitting element, the print target W And a light receiving element that receives the reflected light.
（コンペンセータローラ）
　グラビア印刷ユニットには、版胴１１ａ、１１ｂ、１１ｃの上流側に、図１の矢印方向に移動して印刷対象物Ｗの見当合わせを行う印刷対象物の位置調整手段として機能するコンペンセータローラ１４ａ、１４ｂ、１４ｃが各々配置されている。 (Compensator roller)
The gravure printing unit includes a compensator roller 14a that functions as a print object position adjusting unit that moves in the direction of the arrow in FIG. 1 and registers the print object W upstream of the plate cylinders 11a, 11b, and 11c. 14b and 14c are respectively arranged.
　図１に示すように、コンペンセータローラ１４ａ、１４ｂ、１４ｃは、グラビア印刷ユニットにおいて印刷を行う際に、印字ユニット４０ａにおいて印字された基準見当マークとグラビア印刷ユニット１０ａ、１０ｂ、１０ｃにおいて行われた見当マークとの印刷対象物Ｗの流れ方向Ｖの見当合わせを行うための装置である。 As shown in FIG. 1, when the compensator rollers 14a, 14b, and 14c perform printing in the gravure printing unit, the reference registration marks printed in the printing unit 40a and the registration performed in the gravure printing units 10a, 10b, and 10c are used. This is an apparatus for registering the flow direction V of the printing object W with the mark.
　コンペンセータローラ１４ａ、１４ｂ、１４ｃは、後述する見当コントローラに検出された見当ずれの検出信号に基づいて、印字ユニット４０ａとグラビア印刷ユニット１０ａ、１０ｂ、１０ｃ間、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃ間の印刷対象物Ｗの経路長を調節することにより流れ方向Ｖの見当合わせを行うことができる。このためコンペンセータローラ１４ａ、１４ｂ、１４ｃは見当マーク位置ずれ調整手段として機能する。 The compensator rollers 14a, 14b, and 14c are connected between the printing unit 40a and the gravure printing units 10a, 10b, and 10c, and between the gravure printing units 10a, 10b, and 10c, based on a detection signal that is detected by a registration controller that will be described later. The flow direction V can be registered by adjusting the path length of the printing object W. Therefore, the compensator rollers 14a, 14b, and 14c function as registration mark position deviation adjusting means.
（サイドレモータ）
　各グラビア印刷ユニットには、版胴を幅方向に移動させ当該版胴の幅方向における位置を調整するサイドレモータ１７が配置されている。 (Side remotor)
Each gravure printing unit is provided with a side motor 17 that moves the plate cylinder in the width direction and adjusts the position of the plate cylinder in the width direction.
　サイドレモータ１７は、各グラビア印刷ユニットにおいて印刷を行う際に、印字ユニット４０ａにおいて印字された基準見当マークとグラビア印刷ユニット１０ａ、１０ｂ、１０ｃにおいて行われた見当マークとの版胴の幅方向における見当合わせを行うための装置である。 The side motor 17 performs printing in each gravure printing unit in the width direction of the plate cylinder between the reference registration mark printed in the printing unit 40a and the registration mark made in the gravure printing units 10a, 10b, and 10c. It is a device for performing registration.
　サイドレモータ１７は、後述する見当コントローラに検出された見当ずれの検出信号に基づいて、版胴の幅方向におけるこれらの２つの見当マークの座標が一致するよう、版胴１１ａ、１１ｂ、１１ｃの幅方向位置を調整することにより見当合わせを行うことができる。 The side motor 17 detects the registration of the plate cylinders 11a, 11b, and 11c so that the coordinates of these two registration marks in the width direction of the plate cylinder coincide with each other based on a detection signal of a registration deviation detected by a registration controller described later. Registration can be performed by adjusting the position in the width direction.
（見当制御装置）
　見当制御装について図２を参照して説明する。図２は、本発明の一実施形態による見当合わせ装置の構成を示す概略図である。他のグラビア印刷ユニットについても同様であるから、ここでは先頭の第１のグラビア印刷ユニット１０ａの見当制御だけを説明する。 (Register control device)
The registration control device will be described with reference to FIG. FIG. 2 is a schematic diagram illustrating the configuration of a registration device according to an embodiment of the present invention. Since the same applies to the other gravure printing units, only the registration control of the first first gravure printing unit 10a will be described here.
　グラビア印刷機は、印字ユニットの基準見当マーク７、および各グラビア印刷ユニットの見当マーク８ａの検出設定条件を入力する入力部３１と、見当コントローラ３２からなる制御装置３０を更に有している。 The gravure printing machine further includes a control unit 30 including an input unit 31 for inputting detection setting conditions for the reference registration mark 7 of the printing unit and the registration mark 8a of each gravure printing unit, and a registration controller 32.
　見当コントローラ３２は、各印刷ユニットにおけるコンペンセータローラを制御してその位置を調整する。例えば、第１のグラビア印刷ユニット１０ａのコンペンセータローラ１４ａの位置は、見当マーク検出センサ１５ａにより検出された印刷対象物Ｗ上の基準見当マーク７および見当マーク８ａの位置に基づいて見当ずれの大きさを調整するようになっている。 The register controller 32 controls the compensator roller in each printing unit and adjusts its position. For example, the position of the compensator roller 14a of the first gravure printing unit 10a is based on the position of the reference registration mark 7 and the registration mark 8a on the printing object W detected by the registration mark detection sensor 15a. To be adjusted.
　見当コントローラ３２は、見当ずれが発生していた場合に、入力部３１において入力された見当マーク検出設定条件に対応する見当ずれ調整量に基づいて、コンペン駆動モータ１６の制御量を算出し、算出されたコンペン駆動モータ１６の制御量に基づいてコンペンセータローラ１４ａを制御して、各グラビア印刷ユニット間の印刷対象物Ｗの経路長を調節するコンペン駆動モータ制御器を有している。 The registration controller 32 calculates the control amount of the compensation drive motor 16 based on the registration deviation adjustment amount corresponding to the registration mark detection setting condition input in the input unit 31 when the registration deviation occurs. The compensator roller 14a is controlled on the basis of the control amount of the compensator driving motor 16 to adjust the path length of the printing object W between the gravure printing units.
　また、見当コントローラ３２は、各グラビア印刷ユニットの見当マーク検出センサ１５ａにより検出された印刷対象物Ｗ上の基準見当マーク７、および見当マーク８ａに基づいて、各々のサイドレモータ１７を制御して版胴の幅方向位置を調整するサイドレ駆動モータ制御器を有している。 The register controller 32 controls each side motor 17 based on the reference register mark 7 and the register mark 8a on the print object W detected by the register mark detection sensor 15a of each gravure printing unit. It has a side drive motor controller that adjusts the position of the plate cylinder in the width direction.
（印刷対象物）
　図３は、図１の印刷機によって絵柄印刷された印刷対象物Ｗの概略平面図である。 (Print object)
FIG. 3 is a schematic plan view of the printing object W that has been subjected to pattern printing by the printing machine of FIG.
　印刷対象物Ｗは、少なくとも流れ方向ｖに複数の印刷領域６を有するものであり、幅方向ｘにも複数の印刷領域６を有していてもよい。また、印刷対象物Ｗは、グラビア印刷機における最後尾の印刷ユニット、つまり、図１における印刷ユニット１０ｃで印刷した後、印刷領域６毎に打ち抜いてもよい。例えば、印刷領域６毎に打ち抜いた枚葉シートは、包装材料やカードなどに使用することができる。 The print object W has a plurality of print areas 6 at least in the flow direction v, and may have a plurality of print areas 6 also in the width direction x. Further, the printing object W may be punched for each printing region 6 after printing by the last printing unit in the gravure printing machine, that is, the printing unit 10c in FIG. For example, a sheet sheet punched for each printing region 6 can be used for packaging materials, cards, and the like.
　印字ユニットのプリントヘッドにより付けられる基準見当マーク７と、各グラビア印刷ユニットの版胴により印刷対象物Ｗに付けられる見当マーク８ａ、８ｂ、８ｃの位置について図３を用いて説明する。 The position of the reference register mark 7 attached by the print head of the printing unit and the register marks 8a, 8b, 8c attached to the printing object W by the plate cylinder of each gravure printing unit will be described with reference to FIG.
　図３に示すように、印刷対象物Ｗに付けられる基準見当マーク７および見当マーク８ａ、８ｂ、８ｃの位置は余白であって、印刷対象物Ｗの幅方向における端部近傍となっている。 As shown in FIG. 3, the positions of the reference register mark 7 and the register marks 8a, 8b, and 8c attached to the print object W are blank, and are near the end in the width direction of the print object W.
〔作用〕
　次にこのような構成からなるインライン方式の印刷機の作用について図１を用いて説明する。 [Action]
Next, the operation of the in-line type printer having such a configuration will be described with reference to FIG.
　まず、図１に示すインクジェット印字装置とグラビア印刷機をインライン形式で設けた印刷装置の全体の動作について説明する。 First, the overall operation of the printing apparatus provided with the inkjet printing apparatus and gravure printing machine shown in FIG.
　給紙部１の送りローラ４から巻き解かれた無地の印刷対象物Ｗが、インフィードユニット２０に送られ、このインフィードユニット２０において印刷対象物Ｗにテンションが与えられる。このことにより、印刷対象物Ｗの印刷ピッチが、印刷対象物Ｗに与えられるテンションの大きさに応じて調整される。次に、印刷対象物Ｗはインフィードユニット２０からインクジェット印字装置４０による印字ユニット４０ａに送られ、印字ユニット４０ａでプリントヘッド４１により印刷対象物Ｗに基準見当マーク７が付けられる。なお、プリントヘッド４１により印刷対象物Ｗの印刷領域６あるいは余白の少なくともいずれかに可変情報が付与されてもよい。 The plain print object W unwound from the feed roller 4 of the paper feed unit 1 is sent to the infeed unit 20, and tension is applied to the print object W in the infeed unit 20. Thereby, the printing pitch of the printing object W is adjusted according to the magnitude of the tension applied to the printing object W. Next, the printing object W is sent from the infeed unit 20 to the printing unit 40a by the inkjet printing apparatus 40, and the reference registration mark 7 is attached to the printing object W by the print head 41 in the printing unit 40a. Note that variable information may be given to at least one of the print area 6 and the margin of the print object W by the print head 41.
　しかる後、印刷対象物Ｗはグラビア印刷ユニット１０ａ、１０ｂ、１０ｃに送られ、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃにおいてそれぞれ、圧胴１２ａ、１２ｂ、１２ｃにより版胴１１ａ、１１ｂ、１１ｃに密着され印圧が加えられて、印刷対象物Ｗに対して各色の印刷が行われる。このときに、プリントヘッド４１、版胴１１ａ、１１ｂ、１１ｃにより印刷対象物Ｗにそれぞれ第１の見当マーク８ａ、第２の見当マーク８ｂ、第３の見当マーク８ｃがそれぞれ付けられる。続いて、印刷対象物Ｗはガイドローラにより導かれ、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃ内の図示しない乾燥ユニットより印刷インキの乾燥が行われる。 Thereafter, the printing object W is sent to the gravure printing units 10a, 10b, and 10c, and in each of the gravure printing units 10a, 10b, and 10c, the printing cylinders 11a, 11b, and 11c are brought into close contact with the impression cylinders 12a, 12b, and 12c, respectively. Printing pressure is applied, and printing of each color is performed on the printing object W. At this time, the first registration mark 8a, the second registration mark 8b, and the third registration mark 8c are respectively attached to the print object W by the print head 41 and the plate cylinders 11a, 11b, and 11c. Subsequently, the printing object W is guided by the guide roller, and the printing ink is dried by a drying unit (not shown) in each of the gravure printing units 10a, 10b, and 10c.
　グラビア印刷ユニット１０ａ、１０ｂ、１０ｃにおいて、印刷対象物Ｗ上に付けられた基準見当マーク７および見当マーク８ａ、８ｂ、８ｃが、見当マーク検出センサ１５ａ、１５ｂ、１５ｃにより検出され、この印刷対象物Ｗ上における基準見当マーク７および見当マーク８ａ、８ｂ、８ｃの位置の信号が制御装置の見当コントローラに送られる。そして、コンペンセータローラ１４ａ、１４ｂ、１４ｃは、見当コントローラから送られた印刷対象物Ｗ上の基準見当マークを基準として見当マークの相対的な位置ずれの情報に基づいて算出される操作量に応じてその位置が変化し、このことにより版胴１１ａ、１１ｂ、１１ｃに送られる印刷対象物Ｗの流れ方向Ｖの見当合わせを行う。つまり、コンペンセータローラ１４ａは基準見当マーク７と第１の見当マーク８ａの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、コンペンセータローラ１４ｂは基準見当マーク７と第２の見当マーク８ｂの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、コンペンセータローラ１４ｃは基準見当マーク７と第３の見当マーク８ｃの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、印刷対象物Ｗの流れ方向Ｖの見当合わせを行うことができる。 In the gravure printing units 10a, 10b, and 10c, the reference register mark 7 and the register marks 8a, 8b, and 8c attached on the print object W are detected by the register mark detection sensors 15a, 15b, and 15c. The signals of the positions of the reference register mark 7 and the register marks 8a, 8b, 8c on W are sent to the register controller of the control device. Then, the compensator rollers 14a, 14b, and 14c correspond to the operation amount calculated based on the information on the relative misalignment of the registration mark with reference to the reference registration mark on the print object W sent from the registration controller. The position changes, and thereby the registration of the flow direction V of the printing object W sent to the plate cylinders 11a, 11b, and 11c is performed. That is, the position of the compensator roller 14a changes according to the amount of operation calculated based on the information on the relative displacement between the reference register mark 7 and the first register mark 8a, and the compensator roller 14b The position changes in accordance with the amount of operation calculated based on the information on the relative displacement of the second register mark 8b, and the compensator roller 14c has a relative position between the reference register mark 7 and the third register mark 8c. The position changes in accordance with the operation amount calculated based on the deviation information, and registration of the flow direction V of the print target W can be performed.
　また、隣接する２つの印刷ユニット間で印刷された見当マーク同士の相対的な位置ずれ情報に基づいて算出されるコンペンセータローラ１４ｂ、１４ｃの操作量に応じてその位置が変化させて隣接する印刷ユニット間の見当合わせを行うこともできる。つまり、コンペンセータローラ１４ａは基準見当マーク７と第１の見当マーク８ａの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、コンペンセータローラ１４ｂは第１の見当マーク８ａと第２のマーク８ｂの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、コンペンセータローラ１４ｃは第２の見当マーク８ｂと第３の見当マーク８ｃの相対的な位置ずれの情報に基づいて算出される操作量に応じて位置が変化し、印刷対象物Ｗの流れ方向Ｖの見当合わせを行うこともできる。 Also, adjacent printing units that change their positions in accordance with the amount of operation of the compensator rollers 14b and 14c calculated based on the relative displacement information between the registration marks printed between the two adjacent printing units. You can also register between them. That is, the position of the compensator roller 14a changes in accordance with the amount of operation calculated based on the information on the relative displacement between the reference register mark 7 and the first register mark 8a, and the compensator roller 14b has the first register mark 14b. The position changes in accordance with the operation amount calculated based on the information on the relative positional deviation between the second mark 8b and the second mark 8b, and the compensator roller 14c has a relative relationship between the second register mark 8b and the third register mark 8c. The position changes in accordance with the operation amount calculated based on the information on the general misalignment, and the flow direction V of the print target W can be registered.
　また、サイドレモータは、見当コントローラから送られた印刷対象物Ｗ上の基準見当マークおよび見当マークの位置の情報に基づいて算出される操作量に応じて版胴の幅方向の位置が変化し、このことにより印刷対象物Ｗの幅方向Ｘの見当合わせを行う。 Further, the position of the side cylinder in the width direction of the plate cylinder changes according to the operation amount calculated based on the reference register mark on the print object W and the position information of the register mark sent from the register controller. In this way, registration in the width direction X of the printing object W is performed.
　印刷部２において印字、印刷、乾燥が行われた印刷対象物Ｗは巻取部３に供給される。 The printing object W that has been printed, printed, and dried in the printing unit 2 is supplied to the winding unit 3.
　巻取部３ではその印刷対象物Ｗを巻き取り、巻取ローラ５を形成する。 The winding unit 3 winds the printing object W and forms a winding roller 5.
　次に、本発明の一実施形態による制御装置３０の見当コントローラ３２で実行される見当制御の動作の過程について、図４を参照して説明する。図４は、本発明の一実施形態による見当制御の過程を示すフロー図である。他のグラビア印刷ユニットについても同様であるから、ここでは先頭の第１のグラビア印刷ユニット１０ａのコンペンセータローラ１４ａの位置を変更する過程についてだけ説明する。 Next, the process of register control executed by the register controller 32 of the control device 30 according to an embodiment of the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing a process of register control according to an embodiment of the present invention. Since the same applies to the other gravure printing units, only the process of changing the position of the compensator roller 14a of the first first gravure printing unit 10a will be described here.
　まず、図４のステップＳ１において、第１のグラビア印刷ユニット１０ａの見当マーク検出センサ１５ａは先行して印刷対象物Ｗに印刷されている基準となる基準見当マーク７と、第１のグラビア印刷ユニット１０ａにおいて印刷が行われた見当マークである第１の見当マーク８ａとを検出し検出信号を出力する。 First, in step S1 of FIG. 4, the registration mark detection sensor 15a of the first gravure printing unit 10a has a reference registration mark 7 as a reference that has been printed on the print object W in advance, and the first gravure printing unit. The first registration mark 8a, which is the registration mark printed in 10a, is detected and a detection signal is output.
　次にステップＳ２において、見当コントローラ３２は見当マーク検出センサ１５ａから検出信号を入力して、基準見当マーク７と第１の見当マーク８ａの相対的な所定の位置からのずれ量である見当ずれ量を演算し出力する。 Next, in step S2, the registration controller 32 inputs a detection signal from the registration mark detection sensor 15a, and a registration deviation amount that is a relative deviation between the reference registration mark 7 and the first registration mark 8a from a predetermined position. Is calculated and output.
　これらステップＳ１とステップＳ２の過程は版胴１１ａが１回転する度に繰り返し行われる。 These steps S1 and S2 are repeated every time the plate cylinder 11a rotates once.
　この場合、見当コントローラ３２では印刷対象物Ｗの基準見当マーク７と第１の見当マーク８ａの位置関係が設定範囲であるか否か確認する。そしてこの位置関係が設定範囲内のとき、見当制御が終了する。他方、この位置関係が設定範囲を越えたとき、ステップ３に進む。 In this case, the register controller 32 checks whether the positional relationship between the reference register mark 7 and the first register mark 8a of the print target W is within the set range. When this positional relationship is within the set range, the registration control is terminated. On the other hand, when this positional relationship exceeds the set range, the process proceeds to step 3.
　ステップＳ３において、第１の見当マーク８ａに対して基準見当マーク７が印刷対象物Ｗの走行方向の側（下流）に見当ずれしているときには、見当ずれ量は正（印刷が進んでいる）であるので、コンペン駆動モータ１６の回転速度を速くして、コンペンセータローラ１４ａを印刷対象物Ｗの経路長を長くする方向である上方に移動させるように制御が行われる。 In step S3, when the reference registration mark 7 is misregistered to the traveling direction side (downstream) of the printing object W with respect to the first registration mark 8a, the misregistration amount is positive (printing progresses). Therefore, the control is performed such that the compensator roller 14a is moved upward, which is the direction in which the path length of the print target W is increased, by increasing the rotational speed of the compensator drive motor 16.
　第１の見当マーク８ａに対して基準見当マーク７が印刷対象物Ｗの走行方向の反対側（上流）に見当ずれしているときには、見当ずれ量は負（印刷が遅れている）であるので、コンペン駆動モータ１６の回転速度を遅くして、コンペンセータローラ１４ａを印刷対象物Ｗの経路長を短くする方向である下方に移動させるように制御が行われる。 When the reference register mark 7 is misregistered with respect to the first register mark 8a on the opposite side (upstream) of the printing object W in the traveling direction, the misregistration amount is negative (printing is delayed). The compensator roller 14a is controlled so as to move downward in the direction of shortening the path length of the print object W by slowing the rotation speed of the compensator drive motor 16.
　また、第１の見当マーク８ａに対して基準見当マーク７が版胴１１ａの幅方向Ｘに見当ずれしているときには、この第１の見当マーク８ａと基準見当マーク７の座標が一致するように、サイドレモータの制御量を調整する。 When the reference register mark 7 is misregistered in the width direction X of the plate cylinder 11a with respect to the first register mark 8a, the coordinates of the first register mark 8a and the reference register mark 7 are matched. Adjust the control amount of the sideless motor.
　その後、再びステップＳ１に戻って、印刷対象物Ｗの基準マーク７と第１見当マーク８ａを見当マーク検出センサ１５ａにより検出し、基準マーク７と第１見当マーク８ａとの位置関係が設定範囲に収まるまで、上述の制御が繰り返される。 Thereafter, the process returns to step S1, and the reference mark 7 and the first registration mark 8a of the printing object W are detected by the registration mark detection sensor 15a, and the positional relationship between the reference mark 7 and the first registration mark 8a is within the set range. The above-mentioned control is repeated until it is settled.
　この見当制御により、グラビア印刷の第１ユニット１０ａが薄色の印刷材料であっても、グラビア印刷の第１ユニット１０ａの上流に配置される印字ユニット４０ａで、基準となる基準見当マーク７を印刷対象物Ｗに印字することができるので、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃのコンペンセータローラ１４ａ、１４ｂ、１４ｃが印刷対象物Ｗ上の見当マークの位置情報に基づいて印刷対象物Ｗの見当合わせを行うことが可能であり、印字ユニット４０ａと、各グラビア印刷ユニット１０ａ、１０ｂ、１０ｃ間で印刷対象物Ｗに印刷した絵柄の見当合わせを安定して精度良く行うことができる。 With this registration control, even if the first gravure printing unit 10a is a light color printing material, the reference registration mark 7 serving as a reference is printed by the printing unit 40a arranged upstream of the first gravure printing unit 10a. Since printing can be performed on the object W, the compensator rollers 14a, 14b, and 14c of the gravure printing units 10a, 10b, and 10c register the printing object W based on the position information of the registration marks on the printing object W. The pattern printed on the printing object W can be stably and accurately registered between the printing unit 40a and the gravure printing units 10a, 10b, and 10c.
〔変形例〕
　なお、本発明におけるインクジェット印字装置を付加したグラビア印刷機の印刷方法は、上記の態様に限定されるものではなく、様々の変更を加えることができる。 [Modification]
In addition, the printing method of the gravure printing machine which added the inkjet printing apparatus in this invention is not limited to said aspect, A various change can be added.
　例えば、グラビア印刷機は、見当マーク位置ずれ調整手段として、コンペンセータローラを用いたコンペンセータ方式のものに限定されることはない。グラビア印刷機の見当マーク位置ずれ調整手段として、セクショナルドライブ方式のものを用いてもよい。 For example, a gravure printing machine is not limited to a compensator type using a compensator roller as a registration mark position deviation adjusting means. As the registration mark position deviation adjusting means of the gravure printing machine, a sectional drive type may be used.
　この場合には、図１に示すコンペンセータ方式のグラビア印刷機と比較して、印刷ユニット１０ａ、１０ｂ、１０ｃにおいてコンペンセータローラ１４ａ、１４ｂ、１４ｃおよびコンペン駆動モータが設置されないようになる。 In this case, the compensator rollers 14a, 14b, 14c and the compensator driving motor are not installed in the printing units 10a, 10b, 10c, as compared with the compensator gravure printing machine shown in FIG.
　セクショナルドライブ方式のグラビア印刷機においては、各印刷ユニット１０ａ、１０ｂ、１０ｃの版胴１１ａ、１１ｂ、１１ｃは、それぞれ対応するサイドレモータ（版胴駆動モータ）により回転駆動されているが、これらのサイドレモータのモータ回転速度はサーボドライバによりそれぞれ調整されるようになる。この際に、サーボドライバは、それぞれサイドレモータに設けられたパルスジェネレータにより検出された実際のサイドレモータのモータ回転速度を、各々見当コントローラにより算出された目標モータ回転速度に近づけるように各版サイドレモータに送るモータ駆動電流の大きさをそれぞれ調整するようになっている。 In the sectional drive type gravure printing machine, the plate cylinders 11a, 11b, and 11c of the printing units 10a, 10b, and 10c are rotationally driven by corresponding side motors (plate cylinder drive motors). The motor rotation speed of the side motor is adjusted by the servo driver. At this time, each servo driver makes the motor speed of the actual side motor detected by the pulse generator provided in the side motor close to the target motor speed calculated by the register controller. The magnitude of the motor drive current sent to the side motor is adjusted.
　セクショナルドライブ方式のグラビア印刷機においては、入力部３１により見当マーク検出設定条件を入力すると、各印刷ユニット１０ａ、１０ｂ、１０ｃについて、見当ずれの大きさを、入力部３１により入力された見当マーク検出設定条件の見当ずれ調整量に基づいて修正し、修正後の見当ずれの大きさに基づいてサイドレモータの制御量を算出するようになっている。このように、セクショナルドライブ方式のグラビア印刷機でも、見当ずれの微調整を行うことにより、見当合わせを効率的に行うことができる。 In the sectional drive type gravure printing machine, when the registration mark detection setting condition is input by the input unit 31, the size of the registration error is detected for each of the printing units 10a, 10b, and 10c. The correction is made based on the registration deviation adjustment amount of the setting condition, and the control amount of the sideless motor is calculated based on the magnitude of the registration deviation after the correction. As described above, even in the sectional drive type gravure printing machine, the registration can be efficiently performed by finely adjusting the registration deviation.
　あるいはまた、グラビア印刷機の見当マーク位置ずれ調整手段として、インクジェット印字装置中に印字タイミング調整手段を設け、この印字タイミング調整手段により見当マーク位置ずれを調整してもよい。 Alternatively, as the registration mark position deviation adjusting means of the gravure printing machine, printing timing adjustment means may be provided in the ink jet printing apparatus, and the registration mark position deviation may be adjusted by this printing timing adjustment means.

　図８に示すように、給紙部１の送りローラ４から巻き解かれた無地のシート材Ｗは、インフィードユニット２０に送られ、インフィードローラ２１と圧胴２３との間で挟持され、シート材Ｗにテンションが与えられる。 As shown in FIG. 8, the plain sheet material W unwound from the feed roller 4 of the paper feeding unit 1 is sent to the infeed unit 20 and is sandwiched between the infeed roller 21 and the impression cylinder 23. A tension is applied to the sheet material W.
　インフィードユニット２０の基本的な構成は、回転駆動するインフィードローラ２１と、インフィードローラ２１との間でシート材Ｗを挟持する圧胴２３と、インフィードローラ２１の下流側に設けられ、図８の矢印方向に移動自在であるダンサーローラ２２を有している。 The basic configuration of the infeed unit 20 is provided on the downstream side of the infeed roller 21 that rotates, the pressure drum 23 that sandwiches the sheet material W between the infeed roller 21, and the infeed roller 21.

The print head 41 is a device that prints by injecting ink onto the sheet material W by an inkjet method. The print head 41 prints variable information and inkjet print registration marks on the sheet material W. The printer control unit 42 is a control unit that comprehensively controls the inkjet printing apparatus 40. The printer control unit 42 controls the printer driving roller and the print head 41 based on the input information. The printer control unit 42 can print electronic information by electrical control according to a preset program.
　インクジェット印刷工程は、まず、シート材Ｗには、プリントヘッドから噴射されたインクジェットインキによって、可変情報９が製品部６に印刷されると連動してインクジェット印字見当マーク７がシート材Ｗ印刷される。 In the inkjet printing process, first, on the sheet material W, the inkjet printing registration mark 7 is printed on the sheet material W in conjunction with the variable information 9 being printed on the product portion 6 by the inkjet ink ejected from the print head. .
　更に、シート材Ｗ上のインクを乾燥させるための乾燥機４３を通って乾燥が行われてもよい。シート材Ｗには、赤外線や紫外線などの光が照射されて、シート材Ｗ上に印刷されたインクジェットインキを乾燥させることができる。なお、乾燥とは、熱エネルギーを与えてインクジェットインキの溶媒を蒸発させることやインクジェットインキを硬化させることを含む。 Further, drying may be performed through a dryer 43 for drying the ink on the sheet material W. The sheet material W is irradiated with light such as infrared rays or ultraviolet rays, and the ink-jet ink printed on the sheet material W can be dried. Drying includes applying thermal energy to evaporate the solvent of the inkjet ink and curing the inkjet ink.
　また、シート材Ｗは、乾燥機４３を通って乾燥して輪転印刷部にて印刷を行う前に、更に、裏面に輪転印刷機で印刷するためのターンバー４５によって、シート材Ｗの表裏を反転させてもよい。 Further, before the sheet material W is dried through the dryer 43 and printed by the rotary printing unit, the front and back of the sheet material W are reversed by the turn bar 45 for printing on the reverse side by the rotary printing machine. You may let them.
　シート材Ｗは、輪転印刷ユニット１０ａ、１０ｂ、１０ｃにおいて、圧胴１２ａ、１２ｂ、１２ｃにより版胴１１ａ、１１ｂ、１１ｃに密着され印圧が加えられて、版胴１１ａ、１１ｂ、１１ｃと圧胴１２ａ、１２ｂ、１２ｃとの間を通過することによって、シート材Ｗに対して製品部６に輪転印刷画像部７０ａ、７０ｂ、７０ｃと輪転印刷見当マーク８ａ、８ｂ、８ｃが同時に印刷される。シート材Ｗはガイドローラにより導かれ、輪転印刷ユニット１０ａ、１０ｂ、１０ｃ内の乾燥機により印刷インキの乾燥が行われる。 In the rotary printing units 10a, 10b, and 10c, the sheet material W is brought into close contact with the plate cylinders 11a, 11b, and 11c by the impression cylinders 12a, 12b, and 12c, and printing pressure is applied to the plate cylinders 11a, 11b, and 11c. By passing between 12a, 12b and 12c, the rotary printing image portions 70a, 70b and 70c and the rotary printing registration marks 8a, 8b and 8c are simultaneously printed on the product portion 6 on the sheet material W. The sheet material W is guided by a guide roller, and the printing ink is dried by a dryer in the rotary printing units 10a, 10b, and 10c.
　なお、通常、輪転印刷の見当ずれの限度は０．５ｍｍ未満であるので、見当マーク検出センサ１５ａ、１５ｂ、１５ｃの精度（検知能力）は０．１～０．２ｍｍに設定されている。 In addition, since the limit of misregistration for rotary printing is usually less than 0.5 mm, the accuracy (detection ability) of the register mark detection sensors 15a, 15b, and 15c is set to 0.1 to 0.2 mm.
　見当マーク検出センサ１５ａ、１５ｂ、１５ｃは、ＬＥＤ等の発光素子と、シート材Ｗに対して発光素子と反対側に設けられ、発光素子から発せられた光を反射する反射板と、シート材Ｗに対して発光素子と同じ側に設けられ、発光素子から発せられ、反射板により反射した光を受ける受光素子とを有している。 The registration mark detection sensors 15a, 15b, and 15c are provided on a side opposite to the light emitting element with respect to the light emitting element such as an LED, the reflector that reflects the light emitted from the light emitting element, The light receiving element is provided on the same side as the light emitting element and receives light emitted from the light emitting element and reflected by the reflecting plate.
　輪転印刷ユニット１０ａ、１０ｂ、１０ｃとしては、グラビア印刷ユニットの他、オフセット印刷ユニット、フレキソ印刷ユニットが用いられる。中でも、グラビア印刷ユニットは、高速で大量に印刷できる点で好ましい。 As the rotary printing units 10a, 10b, and 10c, an offset printing unit and a flexographic printing unit are used in addition to a gravure printing unit. Among them, the gravure printing unit is preferable in that it can print a large amount at a high speed.
　なお、図８において、Ｗはシート材、４は送りローラ、５は巻取ローラである。 In FIG. 8, W is a sheet material, 4 is a feed roller, and 5 is a take-up roller.
　図１０は、第２－１実施形態の輪転印刷ユニット１０ａ、１０ｂ、１０ｃを用いて固定情報と可変情報と見当マークが形成されたシート材Ｗの一例を説明する説明図である。 FIG. 10 is an explanatory diagram for explaining an example of the sheet material W on which fixed information, variable information, and registration marks are formed using the rotary printing units 10a, 10b, and 10c according to the 2-1 embodiment.
　図１０に示すように、固定情報８０および可変情報９はシート材Ｗの製品部６に形成される。固定情報８０は、例えば、輪転印刷画像部７０ａ、７０ｂ、７０ｃにより形成することができる。ここで、固定情報８０としては、絵柄、文字、図形、記号、番号などが挙げられ、例えば、製品内容などを表示することができる。また、輪転印刷画像部７０ａ、７０ｂ、７０ｃにおいて、各輪転印刷画像部を異なる色にしてもよい。可変情報９としては、連続番号、製造日付、製造ロット番号、ＱＲコード（登録商標）などが挙げられる。 10, the fixed information 80 and the variable information 9 are formed in the product portion 6 of the sheet material W. The fixed information 80 can be formed by, for example, the rotary print image portions 70a, 70b, and 70c. Here, examples of the fixed information 80 include a pattern, a character, a figure, a symbol, a number, and the like. For example, product content can be displayed. Further, in the rotary print image portions 70a, 70b, and 70c, the respective rotary print image portions may have different colors. Examples of the variable information 9 include a serial number, a manufacturing date, a manufacturing lot number, and a QR code (registered trademark).
　また、製品部６はシート材Ｗに多面付けされるものであり、例えば、図１０に示すように、シート材Ｗの幅方向に２列、搬送方向に連続して設けることができる。 Further, the product section 6 is multi-faceted to the sheet material W. For example, as shown in FIG. 10, two rows in the width direction of the sheet material W can be continuously provided in the conveyance direction.
　そして、輪転印刷見当マーク８ａ、８ｂ、８ｃおよびインクジェット印字見当マーク７が、シート材Ｗの幅方向における端部近傍の余白部１８に印刷される。なお、輪転印刷見当マーク８ａ、８ｂ、８ｃは輪転印刷画像部７０ａ、７０ｂ、７０ｃにそれぞれ対応し、インクジェット印字見当マーク７は可変情報９に対応して設けられるものである。 Then, the rotary printing registration marks 8 a, 8 b, 8 c and the inkjet printing registration mark 7 are printed on the margin 18 near the end in the width direction of the sheet material W. The rotary printing registration marks 8a, 8b, and 8c correspond to the rotary printing image portions 70a, 70b, and 70c, respectively, and the inkjet printing registration mark 7 corresponds to the variable information 9.
　なお、複数台の輪転印刷ユニット１０ａ、１０ｂ、１０ｃのうち、少なくとも１つの輪転印刷ユニットを、シート材Ｗ上にオーバープリント層を設けることができるように構成してもよい。オーバープリント層は、シート材Ｗの一部に設けてもよいし、全面に設けてもよい。例えば最上流側の輪転印刷ユニット１０ａを用いてオーバープリント層を設ける場合、このオーバープリント層はシート材Ｗ上にインクジェット印字装置４０によって印字されたインクジェット印字見当マーク７や可変情報９を保護することができるため、インクジェット印字装置４０によって印字されたインクジェット印字見当マーク７や可変情報９によって輪転印刷ユニットのロールが汚染されるのを防止することができる。なお、この場合、オーバープリント層はインクジェット印字見当マーク７や可変情報９が印字された部分のみに設けるようにしてもよい。また、例えば最下流の輪転印刷ユニット１０ｃを用いてシート材Ｗの全面にオーバープリント層を設ける場合、このオーバープリント層はシート材Ｗ上にインクジェット印字装置４０によって印字されたインクジェット印字見当マーク７や可変情報９および上流側の輪転印刷ユニット１０ａ、１０ｂによって印刷された輪転印刷画像部７０ａ、７０ｂおよび輪転印刷見当マーク８ａ、８ｂを保護することができる。なお、この場合、固定情報８０は輪転印刷画像部７０ａ、７０ｂにより形成される。また、オーバープリント層は、シート材Ｗの印刷領域６において、固定情報８０が設けられていない部分に設けるようにしてもよい。 Note that at least one of the plurality of rotary printing units 10a, 10b, and 10c may be configured such that an overprint layer can be provided on the sheet material W. The overprint layer may be provided on a part of the sheet material W or on the entire surface. For example, when an overprint layer is provided by using the most upstream rotary printing unit 10a, the overprint layer protects the inkjet print registration mark 7 and the variable information 9 printed on the sheet material W by the inkjet printer 40. Therefore, it is possible to prevent the roll of the rotary printing unit from being contaminated by the inkjet printing registration mark 7 and the variable information 9 printed by the inkjet printing apparatus 40. In this case, the overprint layer may be provided only on the portion where the ink-jet print registration mark 7 or the variable information 9 is printed. Further, for example, when an overprint layer is provided on the entire surface of the sheet material W using the most downstream rotary printing unit 10c, the overprint layer is formed on the sheet material W by the inkjet printing registration mark 7 or the like. It is possible to protect the variable information 9 and the rotary printing image portions 70a and 70b and the rotary printing registration marks 8a and 8b printed by the upstream rotary printing units 10a and 10b. In this case, the fixed information 80 is formed by the rotary printing image portions 70a and 70b. Further, the overprint layer may be provided in a portion where the fixed information 80 is not provided in the print region 6 of the sheet material W.
　図１１は、図１０のシート材Ｗの製品部６を打ち抜くことにより形成されたブランクを示す概略図である。ブランクは、シート材Ｗに多面付けされた製品部６を打抜き機により打抜かれたものである。ブランクには、固定情報８０と可変情報９が形成されている。 FIG. 11 is a schematic view showing a blank formed by punching the product portion 6 of the sheet material W of FIG. The blank is obtained by punching the product portion 6 multifaceted on the sheet material W by a punching machine. Fixed information 80 and variable information 9 are formed in the blank.
　なお、図１１には、シート材Ｗに各輪転印刷画像部７０ａ、７０ｂ、７０ｃが重ならないように形成された例を示したが、輪転印刷画像部は、全部または一部が重なるように形成されてもよい。 FIG. 11 shows an example in which the respective rotary print image portions 70a, 70b, and 70c are formed so as not to overlap the sheet material W. However, the rotary print image portion is formed so that all or a part thereof overlaps. May be.
　次に、このような構成からなる第２－１実施形態の作用について説明する。 Next, the operation of the 2-1 embodiment having such a configuration will be described.
　図８は、第２－１実施形態の印刷機の構成を示す概略図であり、見当マーク検出センサ１５ａからインクジェット印字装置４０に信号が入力されるように構成される。ここで図１２は、第２－１実施形態の第１輪転印刷ユニットでの加工処理を説明するフロー図であり、図１３は、第２－１実施形態の第２輪転印刷ユニットでの加工処理を説明するフロー図である。 FIG. 8 is a schematic diagram showing the configuration of the printing machine according to the second-first embodiment, and is configured such that a signal is input from the registration mark detection sensor 15a to the inkjet printing apparatus 40.

First, in the rotary printing units 10a, 10b, and 10c, the impression cylinders 12a, 12b, and 12c are simultaneously lowered, and the rotary printing registration marks 8a, 8b, and 8c, the first rotary printing image portion 70a, the second rotary printing image portion 70b, and the third. Printing of the rotary printing image portion 70c is started. Note that step S1 of the registration control method in the second rotary printing unit 10b is a step that is also used as step S1 of the registration control method in the third rotary printing unit 10c.
（工程Ｓ２）
　次に、輪転印刷見当マーク８ａと８ｂを第２輪転ユニットの見当マーク検出センサ１５ｂで検出する。 (Process S2)
Next, the rotary printing registration marks 8a and 8b are detected by the registration mark detection sensor 15b of the second rotary unit.
　見当マーク検出センサ１５ｂで輪転印刷見当マーク８ａと輪転印刷見当マーク８ｂを検出した場合（工程Ｓ２のＹｅｓ）、工程Ｓ３に進む。 When the registration mark detection sensor 15b detects the rotary printing registration mark 8a and the rotary printing registration mark 8b (Yes in step S2), the process proceeds to step S3.
（工程Ｓ３）
　次に、第２輪転印刷ユニット１０ｂの見当制御装置（第２見当制御装置）３０は、輪転印刷見当マーク８ａと輪転印刷見当マーク８ｂとの相対的な位置関係が設定範囲内かを判定する。 (Process S3)
Next, the registration control device (second registration control device) 30 of the second rotary printing unit 10b determines whether the relative positional relationship between the rotary printing registration mark 8a and the rotary printing registration mark 8b is within the set range.
　そして、設定範囲内と判定した場合には（工程Ｓ３のＹｅｓ）見当制御を終了する。一方、設定範囲外と判定した場合には（工程Ｓ３のＮｏ）、工程Ｓ４に進む。これら工程Ｓ２と工程Ｓ３の過程は版胴１１ｂが１回転する度に繰り返し行われる。 And when it determines with it being in a setting range (Yes of process S3), registration control is complete | finished. On the other hand, when it determines with it being out of a setting range (No of process S3), it progresses to process S4. These steps S2 and S3 are repeated every time the plate cylinder 11b rotates once.
（工程Ｓ４）

　上述では、圧胴１２ａ、１２ｂ、１２ｃを同時に下ろす例について説明したが、ばらばらに下ろすようにしてもよい。 In the above description, the example in which the impression cylinders 12a, 12b, and 12c are lowered at the same time has been described, but they may be lowered separately.
　第２－１実施形態の変形例では、一番下流側の輪転印刷ユニット１０ｃで付与される輪転印刷見当マーク、つまり、輪転印刷見当マーク８ｃを基準としている。輪転印刷をグラビア印刷とする場合、上流側の輪転印刷ユニット１０ａから下流側の輪転印刷ユニットに向かって順次濃い色を印刷するように構成される。つまり、上流側の輪転印刷ユニット１０ａで付与される輪転印刷見当マーク８ａに比べて、下流側の輪転印刷ユニット１０ｃで付与される輪転印刷見当マーク８ｃのほうが濃い色で印刷される。そのため、下流側の輪転印刷ユニット１０ｃで付与される輪転印刷見当マーク８ｃをトリガーとすることにより、基準となる輪転印刷見当マーク８ｃを確実に検出するようにすることができる。 In the modified example of the 2-1 embodiment, the rotary printing register mark provided by the most downstream rotary printing unit 10c, that is, the rotary printing register mark 8c is used as a reference. When the rotary printing is gravure printing, it is configured to print dark colors sequentially from the upstream rotary printing unit 10a toward the downstream rotary printing unit. That is, the rotary printing register mark 8c provided by the downstream rotary printing unit 10c is printed in a darker color than the rotary printing register mark 8a provided by the upstream rotary printing unit 10a. Therefore, by using the rotary printing register mark 8c provided by the downstream rotary printing unit 10c as a trigger, the reference rotary printing register mark 8c can be reliably detected.

When each of the plate cylinders 11a, 11b, and 11c is rotated, a rotation signal of the plate cylinder is input to the printer control unit 42 of the inkjet printing unit 40a via the encoder 52.
　なお、上述では、シャフト５１の最も上流側にエンコーダ５２を取り付け、最も下流側に駆動モータ１７が取り付ける例を説明したが、エンコーダ５２および駆動モータ１７の位置はこれに限られない。 In the above description, the encoder 52 is attached to the most upstream side of the shaft 51 and the drive motor 17 is attached to the most downstream side. However, the positions of the encoder 52 and the drive motor 17 are not limited thereto.
　また、上述では、エンコーダ５２を介して版胴の一回転信号をインクジェット印字部４０ａのプリンタ制御部４２に入力する例を説明したが、エンコーダ５２を設けず、シャフトにドグを設け、検出センサでドグの位置を検出して、版胴一回転信号をインクジェット印字部４０ａのプリンタ制御部４２に入力するようにしてもよい。 In the above description, an example in which the rotation signal of the plate cylinder is input to the printer control unit 42 of the inkjet printing unit 40a via the encoder 52 has been described. However, the encoder 52 is not provided, a dog is provided on the shaft, and a detection sensor is used. The position of the dog may be detected, and a plate cylinder rotation signal may be input to the printer control unit 42 of the inkjet printing unit 40a.
　図１９は、固定情報と可変情報と見当マークが形成されたシート材（印刷対象物）Ｗを示す図、図２０は、固定情報と可変情報と見当マークが形成されたシート材Ｗの第２変形例を示す図である。 FIG. 19 shows a sheet material (printing object) W on which fixed information, variable information, and registration marks are formed. FIG. 20 shows a second sheet material W on which fixed information, variable information, and registration marks are formed. It is a figure which shows a modification.
　図１９に示すように、輪転印刷見当マーク８ａ、８ｂ、８ｃとインクジェット印字見当マーク７は、同列でなく、異なる列に設けてもよい。 As shown in FIG. 19, the rotary printing registration marks 8a, 8b, 8c and the inkjet printing registration mark 7 may be provided in different rows instead of the same row.
　また、輪転印刷見当マーク８ａ、８ｂ、８ｃと、インクジェット印字見当マーク７をシート材Ｗの異なる面に設けるようにしてもよい。例えば、図２０に示すように、シート材Ｗの表側に輪転印刷見当マーク８ａ、８ｂ、８ｃおよび固定情報８０を設け、裏側にインクジェット印字見当マーク７および可変情報９を設けてもよい。 Further, the rotary printing registration marks 8a, 8b, 8c and the inkjet printing registration mark 7 may be provided on different surfaces of the sheet material W. For example, as shown in FIG. 20, the rotary printing registration marks 8a, 8b, 8c and the fixed information 80 may be provided on the front side of the sheet material W, and the inkjet printing registration mark 7 and the variable information 9 may be provided on the back side.
　また、上述では、シート材Ｗの搬送方向における見当マークの位置ずれを制御する例を示したが、印刷機にサイドレモータを設けて版胴１１ａ、１１ｂ、１１ｃを幅方向に移動するようにし、シート材の幅方向における見当マークの位置ずれを制御するようにしてもよい。 In the above description, an example in which the registration mark misregistration is controlled in the conveyance direction of the sheet material W has been described. However, a side motor is provided in the printing machine so that the plate cylinders 11a, 11b, and 11c are moved in the width direction. The registration mark position shift in the width direction of the sheet material may be controlled.
　また、上述では、見当マーク位置ずれ調整手段として機能する経路長調整手段として、コンペンセータ方式を説明したが、見当マーク位置ずれ調整手段としてはセクショナルドライブ方式を用いてもよい。この場合には、図８に示したコンペンセータローラ１４ａ、１４ｂ、１４ｃおよびコンペン駆動モータ１６は設けられず、版胴１１ａ、１１ｂ、１１ｃはそれぞれ対応する駆動モータに接続される。このため、各版胴１１ａ、１１ｂ、１１ｃを個別に回転させることができ、駆動モータの回転速度を調整することにより見当マークの位置ずれを調整することができる。 In the above description, the compensator method has been described as the path length adjustment unit that functions as the registration mark position deviation adjustment unit. However, the sectional drive method may be used as the registration mark position deviation adjustment unit. In this case, the compensator rollers 14a, 14b, and 14c and the compensator drive motor 16 shown in FIG. 8 are not provided, and the plate cylinders 11a, 11b, and 11c are connected to the corresponding drive motors. Therefore, the plate cylinders 11a, 11b, and 11c can be individually rotated, and the registration mark misalignment can be adjusted by adjusting the rotation speed of the drive motor.
　あるいはまた、見当マーク位置ずれ調整手段として、インクジェット印字装置中に印字タイミング調整手段を設け、この印字タイミング調整手段により見当マークの位置ずれを調整してもよい。 Alternatively, as the registration mark position deviation adjustment means, a printing timing adjustment means may be provided in the ink jet printing apparatus, and the registration mark position deviation may be adjusted by this printing timing adjustment means.
　また、インフィードユニット２０のインフィールドローラ２１と圧胴２３は、インクジェット印字ユニット４０ａの上流側の配置に限定されず、インクジェット印字ユニット４０ａと最も上流側の第１の輪転印刷ユニット１０ａとの間に配置されていてもよい（図５参照）。 Further, the in-field roller 21 and the impression cylinder 23 of the infeed unit 20 are not limited to the arrangement on the upstream side of the ink jet printing unit 40a, but between the ink jet printing unit 40a and the first rotary printing unit 10a on the most upstream side. (See FIG. 5).
　また、図８に示すようにインクジェット印字ユニット４０ａの上流側にインフィールドユニット２０を設置するとともに、インクジェット印字ユニット４０ａの下流に、更にインフィードロール２１と圧胴２３を追加して配置してもよい。このことにより、シート材Ｗの蛇行を防止することができるので、印字ユニット４０ａにおいて、プリントヘッド４１からインクをシート材Ｗに向けて噴射して見当マークをシート材Ｗに印字する際、シート材Ｗの幅方向Ｘの見当の精度が向上することができる点で好ましい。 Further, as shown in FIG. 8, the in-field unit 20 is installed on the upstream side of the ink jet printing unit 40a, and an infeed roll 21 and an impression cylinder 23 are additionally arranged on the downstream side of the ink jet printing unit 40a. Good. As a result, meandering of the sheet material W can be prevented, and therefore, when the printing unit 40a ejects ink from the print head 41 toward the sheet material W to print the registration mark on the sheet material W, the sheet material W This is preferable in that the registration accuracy of the width direction X of W can be improved.
　また図８において、インクジェット印字装置４０と輪転印刷ユニット１０ａとの間にターンバー４５を設けた例を示したが、このようなターンバー４５はシート材Ｗを反転させるものである。 8 shows an example in which the turn bar 45 is provided between the ink jet printing apparatus 40 and the rotary printing unit 10a. However, the turn bar 45 reverses the sheet material W.
　このようなターンバー４５は図２７に示すように第１ターンローラ４５ａと、第２ターンローラ４５ｂと、第３ターンローラ４５ｃとを有する。 The turn bar 45 has a first turn roller 45a, a second turn roller 45b, and a third turn roller 45c as shown in FIG.
　図２７においてシート材Ｗは表面Ｗａを上方に向けて第１ターンローラ４５ａに入り、第１ターンローラ４５ａでシート材Ｗが反転して裏面Ｗｂを上方に向けて第２ターンローラ４５ｂに入る。次にシート材Ｗは第２ターンローラ４５ｂで反転し、表面Ｗａを上方に向けて第３ターンローラ４５ｃに入り、第３ターンローラ４５ｃでシート材Ｗは再び反転し、裏面Ｗｂを上方へ向けてターンバー４５から出していくようになっている。 Sheet material W in FIG. 27 enters the first turn roller 45a toward the surface W a upward, the second turn roller 45b toward the back surface W b above the sheet material W is inverted by the first turn roller 45a enter. Then the sheet material W is inverted by the second turn roller 45b, enters the third turn roller 45c toward the surface W a upward, the sheet material W is inverted again by the third turn roller 45c, the upper back surface W b It comes out from the turn bar 45 toward.
　なお、このようなターンバー４５を、図１に示すインクジェット印字装置４０とグラビア印刷ユニット１０ａとの間に設け、このターンバー４５によってシート材Ｗを反転させてもよい。また第１ターンローラ４５ａ、第２ターンローラ４５ｂおよび第３ターンローラ４５ｃとしては、シート材Ｗと接触あるいは非接触のローラを用いることができ、また回転ローラあるいは非回転ローラを用いることができる。
＜３－１実施形態＞
　次に図２１（ａ）（ｂ）（ｃ）乃至図２３により、本発明の第３－１実施形態について説明する。第３－１実施形態は、第１－１～第１－３実施形態において、インクジェット印字装置４０の上流側にシート材（印刷対象物）Ｗに対して参照マーク８１を付与する参照マーク付与部８４を設けたものである。 Note that such a turn bar 45 may be provided between the inkjet printing apparatus 40 and the gravure printing unit 10a shown in FIG. 1, and the sheet material W may be reversed by the turn bar 45. Further, as the first turn roller 45a, the second turn roller 45b, and the third turn roller 45c, a roller that is in contact with or not in contact with the sheet material W can be used, and a rotating roller or a non-rotating roller can be used.
<3-1 Embodiment>
Next, a third embodiment of the present invention will be described with reference to FIGS. 21 (a), (b), (c) to FIG. The 3-1 embodiment is a reference mark applying unit that applies a reference mark 81 to a sheet material (print object) W on the upstream side of the ink jet printing apparatus 40 in the 1-1 to 1-3 embodiments. 84 is provided.
　ここで参照マーク８１は印刷対象物Ｗの余白に後述する版胴１１ａの周長単位で等間隔で設けられている。 Here, the reference marks 81 are provided in the margin of the printing object W at equal intervals in the circumferential length unit of the plate cylinder 11a described later.
　第３－１実施形態において、図１乃至図２０に示す第１－１実施形態～第１－３実施形態と同一部分には同一符号を付して詳細な説明は省略する。なお、第３－１実施形態では、輪転印刷ユニットとしてグラビア印刷ユニットを用いる例を説明するが、輪転印刷ユニットとして、オフセット印刷ユニット、フレキソ印刷ユニットなどを用いるようにしてもよい。 In the 3-1 embodiment, the same parts as those in the 1-1 to 1-3 embodiments shown in FIGS. 1 to 20 are denoted by the same reference numerals, and detailed description thereof is omitted. In the third to third embodiments, an example in which a gravure printing unit is used as a rotary printing unit will be described. However, an offset printing unit, a flexographic printing unit, or the like may be used as a rotary printing unit.
　図２１（ａ）（ｂ）（ｃ）乃至図２３に示すように、インクジェット印字装置４０の上流側に、このインクジェット印字装置４０とは別体に、シート材Ｗを給紙する送りローラ８２と、シート材Ｗを巻取る巻取ローラ８３が設けられ、この送りローラ８２と巻取ローラ８３との間にシート材Ｗに対して参照マーク８１を形成する参照マーク付与部８４が設けられている。なお、図２２（ａ）は、図１の印刷機の主要な部分以外を省略して図示した図である。 As shown in FIGS. 21 (a), (b), (c) to FIG. 23, a feed roller 82 for feeding a sheet material W is provided upstream of the ink jet printing apparatus 40, separately from the ink jet printing apparatus 40. A winding roller 83 for winding the sheet material W is provided, and a reference mark applying portion 84 for forming a reference mark 81 for the sheet material W is provided between the feeding roller 82 and the winding roller 83. . Note that FIG. 22A is a diagram in which parts other than the main part of the printing machine of FIG. 1 are omitted.
　次にこのような構成からなる本実施の形態の作用について図２３により説明する。 Next, the operation of the present embodiment having such a configuration will be described with reference to FIG.
　まず送りローラ８２から単層体または積層体からなるシート材Ｗが給紙され、このシート材Ｗに対して参照マーク付与部８４により参照マーク８１が形成される（図２１（ａ）（ｂ）（ｃ）参照）。以下の例では、参照マーク付与部８４がロータリダイカッタなどの打抜加工部からなる例について説明するが、参照マーク付与部８４を参照マーク印刷部からなるようにしてもよい。参照マーク付与部８４が打抜加工部からなる場合、図２１（ｂ）（ｃ）に示すように、シート材Ｗに略三角形状の参照マーク８１が、シート材Ｗを貫通して形成される。 First, a sheet material W made of a single layer or a laminate is fed from a feed roller 82, and a reference mark 81 is formed on the sheet material W by a reference mark applying unit 84 (FIGS. 21A and 21B). (See (c)). In the following example, an example in which the reference mark providing unit 84 is formed by a punching unit such as a rotary die cutter will be described. However, the reference mark providing unit 84 may be formed by a reference mark printing unit. When the reference mark imparting portion 84 is formed by a punching portion, a substantially triangular reference mark 81 is formed through the sheet material W in the sheet material W as shown in FIGS. .
　参照マーク８１が形成されたシート材Ｗは巻取ローラ８３により巻取られる。 The sheet material W on which the reference mark 81 is formed is wound up by a winding roller 83.
　その後シート材Ｗを巻取った巻取ローラ８３は給紙部１に設置されて、給紙部１の送りローラ４となる。 Then, the take-up roller 83 that has wound the sheet material W is installed in the paper feed unit 1 and becomes the feed roller 4 of the paper feed unit 1.
　その後送りローラ４からシート材Ｗが送られ、シート材Ｗはインクジェット印字装置４０へ入る（Ｓ１）。この際、シート材の参照マーク８１が参照マーク検出部８３Ａにより検出され、参照マーク検出部８３Ａからの検出信号がインクジェット印字装置４０へ送られる。次にこの参照マーク８１に基づいて、インクジェット印字装置４０によりインクジェット印字見当マーク７が印字される（Ｓ２）（図２２（ａ）（ｂ）（ｃ）参照）。 Thereafter, the sheet material W is fed from the feed roller 4, and the sheet material W enters the ink jet printing apparatus 40 (S1). At this time, the reference mark 81 of the sheet material is detected by the reference mark detection unit 83A, and a detection signal from the reference mark detection unit 83A is sent to the ink jet printing apparatus 40. Next, based on the reference mark 81, the inkjet printing registration mark 7 is printed by the inkjet printing apparatus 40 (S2) (see FIGS. 22A, 22B, and 22C).
　この場合、インクジェット印字装置４０により、シート材Ｗにインクジェット印字見当マーク７が印字される。また、図２２（ｂ）に示すように、印刷領域６の１つ１つに連続番号、製造日付、製造ロット番号等の可変情報９を印字してもよい。なお、可変情報９は、印刷対象物Ｗの余白に設けるようにしてもよい。 In this case, the inkjet printing registration mark 7 is printed on the sheet material W by the inkjet printing apparatus 40. Further, as shown in FIG. 22B, variable information 9 such as a serial number, a manufacturing date, and a manufacturing lot number may be printed on each printing area 6. The variable information 9 may be provided in the margin of the print target W.
　次に上述した第１－１実施形態～第１－３実施形態と同様に、グラビア印刷ユニットの版胴１１ａにより印刷領域６に絵柄、文字、図形、記号、番号などの輪転印刷画像部が印刷され、さらに輪転印刷見当マーク８ａが印刷される。一つの輪転印刷画像部で絵柄、文字、図形、記号、番号を構成してもよいし、複数の輪転印刷画像部を重ね合せて絵柄、文字、図形、記号、番号を構成してもよい。 Next, as in the first to first embodiments to the first to third embodiments described above, a rotary print image portion such as a pattern, a character, a figure, a symbol, or a number is printed on the printing area 6 by the plate cylinder 11a of the gravure printing unit. Further, a rotary printing register mark 8a is printed. The pattern, characters, figures, symbols, and numbers may be configured by one rotary print image portion, or the patterns, characters, graphics, symbols, and numbers may be configured by overlapping a plurality of rotary print image portions.
　その後、例えば版胴１１ａにより印刷された第１色目の輪転印刷見当マーク８ａと、インクジェット印字見当マーク７が見当マーク検出センサ１５ａにより検出される（Ｓ３）。 Thereafter, for example, the first color rotary printing registration mark 8a printed by the plate cylinder 11a and the inkjet printing registration mark 7 are detected by the registration mark detection sensor 15a (S3).
　第１色目の輪転印刷見当マーク８ａとインクジェット印字見当マーク７との間の位置関係が設定範囲に入っていない場合（Ｓ４）、見当マーク検出センサ１５ａからの検出信号に基づいて、見当制御装置３０（図２参照）によりコンペンセータローラ１４ａが駆動されて見当マーク位置ずれが調整される（Ｓ５）。参照マークを使用する場合、インクジェット印字見当マーク７と輪転印刷見当マーク８ａの位置ずれを調整するときに、インクジェット印字見当マーク７と輪転印刷見当マーク８ａのどちらを基準見当マークとしてもよい。 If the positional relationship between the first color rotary printing registration mark 8a and the inkjet printing registration mark 7 is not within the setting range (S4), the registration control device 30 is based on the detection signal from the registration mark detection sensor 15a. (See FIG. 2), the compensator roller 14a is driven to adjust the registration mark position deviation (S5). When the reference mark is used, when adjusting the positional deviation between the inkjet printing registration mark 7 and the rotary printing registration mark 8a, either the inkjet printing registration mark 7 or the rotary printing registration mark 8a may be used as the reference registration mark.
　他方、第１色目の輪転印刷見当マーク８ａとインクジェット印字見当マーク７との間の位置関係が設定範囲に入っている場合、見当マーク検出センサ１５ａからの検出信号に基づいて見当制御装置３０による調整は行なわれることはなく、見当マーク位置ずれ調整は終了する。 On the other hand, when the positional relationship between the first color rotary printing registration mark 8a and the ink jet printing registration mark 7 is within the set range, the adjustment by the registration control device 30 based on the detection signal from the registration mark detection sensor 15a. The registration mark position deviation adjustment is completed.
　さらに、輪転印刷見当マーク８ｂと、インクジェット印字見当マーク７が検出され、輪転印刷見当マーク８ｂとインクジェット印字見当マーク７との位置関係が設定範囲に入っていない場合、コンペンセータロール１４ｂが駆動されて見当マーク位置ずれが調整される。さらに、輪転印刷見当マーク８ｃと、インクジェット印字見当マーク７が検出され、輪転印刷見当マーク８ｃとインクジェット印字見当マーク７との位置関係が設定範囲に入っていない場合、コンペンセータロール１４ｃが駆動されて見当マーク位置ずれが調整される。なお、上述の例では、インクジェット印字見当マーク７を基準見当マークとして、輪転印刷見当マーク８ｂや輪転印刷見当マーク８ｃとの位置ずれを調整したが、輪転印刷見当マーク８ａを基準見当マークとして、輪転印刷見当マーク８ｂおよび輪転印刷見当マーク８ｃとの位置ずれを調整するようにしてもよい。 Further, when the rotary printing registration mark 8b and the inkjet printing registration mark 7 are detected and the positional relationship between the rotary printing registration mark 8b and the inkjet printing registration mark 7 is not within the setting range, the compensator roll 14b is driven and registered. The mark position deviation is adjusted. Furthermore, when the rotary printing registration mark 8c and the inkjet printing registration mark 7 are detected and the positional relationship between the rotary printing registration mark 8c and the inkjet printing registration mark 7 is not within the set range, the compensator roll 14c is driven and registered. The mark position deviation is adjusted. In the above example, the misregistration with the rotary printing registration mark 8b and the rotary printing registration mark 8c is adjusted using the inkjet printing registration mark 7 as the reference registration mark. However, the rotary printing registration mark 8a is used as the reference registration mark. The positional deviation between the printing registration mark 8b and the rotary printing registration mark 8c may be adjusted.
　このように本実施の形態によれば、インクジェット印字装置４０の上流側に参照マーク付与部８４を設け、この参照マーク付与部８４によりインクジェット印字見当マーク７を印字するためのトリガーとなる参照マーク８１を設けることができるので、この参照マーク８１を用いてインクジェット印字装置４０により精度良くインクジェット印字見当マーク７を印字することができる。さらに、複数の輪転印刷画像部を重ね合せて絵柄、文字、図形、記号、番号が構成される場合、インクジェット印字見当マーク７を用いて複数の輪転印刷画像部の見当合わせを精度良く行うことができる。 As described above, according to the present embodiment, the reference mark applying portion 84 is provided on the upstream side of the ink jet printing apparatus 40, and the reference mark 81 serving as a trigger for printing the ink jet print register mark 7 by the reference mark applying portion 84. Therefore, the inkjet printing register mark 7 can be printed with high accuracy by the inkjet printing apparatus 40 using the reference mark 81. Furthermore, when a plurality of rotary print image portions are superimposed to form a pattern, a character, a figure, a symbol, or a number, the multiple rotary print image portions can be accurately registered using the ink jet print registration mark 7. it can.

Next, a third to second embodiment of the present invention will be described with reference to FIGS. 24 (a) (b) to 25 (a) (b).
　図２１（ａ）（ｂ）（ｃ）乃至図２３に示す第３－１実施形態において、シート材Ｗに打抜加工部からなる参照マーク付与部８４を用いて参照マーク８１を形成する例を示したが、例えば図２４乃至図２５（ａ）（ｂ）に示すようにシート材Ｗの少なくとも一層、例えば基材層Ｗ１を送りローラ８２から繰り出し、基材層Ｗ１に打抜加工部からなる参照マーク付与部８４により参照マーク８１を形成して巻取ローラ８３に巻取ってもよい。なお基材層Ｗ１としては紙層以外にプラスチック基材層などを用いることができる。 In the 3-1 embodiment shown in FIGS. 21A, 21B, 21C to 23, an example in which the reference mark 81 is formed on the sheet material W by using the reference mark applying portion 84 formed of a punching portion.

The reference mark 81 may be formed by the reference mark applying unit 84 and wound on the winding roller 83. In addition to the paper layer, a plastic substrate layer or the like can be used as the substrate layer W1.
　次に巻取ローラ８３から参照マーク８１が形成された基材層Ｗ１が繰り出され（図２５（ａ）参照）、基材層Ｗ１上にアルミ層積層部８６により追加層となるアルミ層Ｗ２が積層され、次に押出ユニット（積層部）８７、８８により基材層Ｗ１上およびアルミ層Ｗ２上に追加層となる樹脂層Ｗ３およびＷ４が順次積層される（図２５（ｂ）参照）。 Next, the base material layer W1 on which the reference mark 81 is formed is drawn out from the winding roller 83 (see FIG. 25A), and an aluminum layer W2 serving as an additional layer is formed on the base material layer W1 by the aluminum layer stacking portion 86. Next, resin layers W3 and W4 that are additional layers are sequentially laminated on the base material layer W1 and the aluminum layer W2 by the extrusion units (lamination parts) 87 and 88 (see FIG. 25B).
　このようにして基材層Ｗ１と、アルミ層Ｗ２と、樹脂層Ｗ３、Ｗ４とを有する積層体からなるシート材Ｗが得られる。このようにして得られたシート材Ｗは巻取ローラ８５に巻取られる。 Thus, a sheet material W composed of a laminate having the base material layer W1, the aluminum layer W2, and the resin layers W3 and W4 is obtained. The sheet material W obtained in this way is wound around the winding roller 85.
　その後、上述と同様にして巻取ローラ８５は給紙部１に設置されて給紙部１の送りローラ４となる。 Thereafter, in the same manner as described above, the take-up roller 85 is installed in the paper feed unit 1 and becomes the feed roller 4 of the paper feed unit 1.
　その後送りローラ４からシート材Ｗが送られてインクジェット装置４０へ入る。 Thereafter, the sheet material W is fed from the feed roller 4 and enters the ink jet apparatus 40.
　なお、上記実施形態において、シート材Ｗが参照マーク８１を有する基材層Ｗ１と、アルミ層Ｗ２と、樹脂層Ｗ３、Ｗ４とを有する例を示したが、これに限らず、シート材Ｗは参照マーク８１を有する基材層Ｗ１と、アルミ層Ｗ２と、樹脂層Ｗ４とを有していてもよい（図２５（ｃ）参照）。また、シート材Ｗは参照マーク８１を有する基材層Ｗ１と、樹脂層Ｗ３、Ｗ４とを有していてもよい（図２５（ｄ）参照）。 In the above embodiment, the sheet material W has an example in which the base material layer W1 having the reference mark 81, the aluminum layer W2, and the resin layers W3 and W4 are shown. You may have the base material layer W1 which has the reference mark 81, the aluminum layer W2, and the resin layer W4 (refer FIG.25 (c)). Further, the sheet material W may include a base material layer W1 having a reference mark 81 and resin layers W3 and W4 (see FIG. 25D).

Alternatively, the reference mark 81 may be provided with a desired arrangement pattern in which a plurality of reference marks arranged at equal intervals are sequentially arranged with a predetermined space.
　次にこのような構成からなる本実施の形態の作用について図２６により説明する。 Next, the operation of the present embodiment having such a configuration will be described with reference to FIG.
　まず送りローラ８２から単層体または積層体からなるシート材Ｗが給紙され、このシート材Ｗに対して参照マーク付与部８４により参照マーク８１が形成される（図２１（ａ）（ｂ）（ｃ）参照）。以下の例では、参照マーク付与部８４がロータリダイカッタなどの打抜加工部からなる例について説明するが、参照マーク付与部８４を参照マーク印刷部からなるようにしてもよい。参照マーク付与部８４が打抜加工部からなる場合、図２１（ｂ）（ｃ）に示すように、シート材Ｗに略三角形状の参照マーク８１が、シート材Ｗを貫通して形成される。 First, a sheet material W made of a single layer or a laminate is fed from a feed roller 82, and a reference mark 81 is formed on the sheet material W by a reference mark applying unit 84 (FIGS. 21A and 21B). (See (c)). In the following example, an example in which the reference mark providing unit 84 is formed by a punching unit such as a rotary die cutter will be described. However, the reference mark providing unit 84 may be formed by a reference mark printing unit. When the reference mark imparting portion 84 is formed by a punching portion, a substantially triangular reference mark 81 is formed through the sheet material W in the sheet material W as shown in FIGS. .
　参照マーク８１が形成されたシート材Ｗは巻取ローラ８３により巻取られる。 The sheet material W on which the reference mark 81 is formed is wound up by a winding roller 83.
　その後シート材Ｗを巻取った巻取ローラ８３は給紙部１に設置されて、給紙部１の送りローラ４となる。 Then, the take-up roller 83 that has wound the sheet material W is installed in the paper feed unit 1 and becomes the feed roller 4 of the paper feed unit 1.
　その後送りローラ４からシート材Ｗが送られ、シート材Ｗはインクジェット装置４０へ入る（Ｓ１）。この際、シート材の参照マーク８１が参照マーク検出部８３Ａにより検出され、参照マーク検出部８３Ａからの検出信号がインクジェット印字装置４０へ送られる。次にこの参照マーク８１に基づいて、インクジェット印字装置４０により連続番号、製造日付、製造ロット番号等の可変情報９が印字される（Ｓ２）（図２２（ａ）（ｂ）参照）。可変情報９は、図２２（ｂ）に示すように、印刷領域６の１つ１つに印字することができる。また、図２２（ｂ）に示すように、印刷対象物Ｗの余白にインクジェット印字見当マーク７を印字してもよい。 Thereafter, the sheet material W is fed from the feed roller 4, and the sheet material W enters the ink jet apparatus 40 (S1). At this time, the reference mark 81 of the sheet material is detected by the reference mark detection unit 83A, and a detection signal from the reference mark detection unit 83A is sent to the ink jet printing apparatus 40. Next, based on the reference mark 81, variable information 9 such as a serial number, a manufacturing date, and a manufacturing lot number is printed by the ink jet printer 40 (S2) (see FIGS. 22A and 22B). The variable information 9 can be printed on each of the print areas 6 as shown in FIG. Further, as shown in FIG. 22B, an inkjet print registration mark 7 may be printed on the margin of the print object W.
　次に上述した第１－１実施形態～第１－３実施形態と同様に、グラビア印刷ユニットの版胴１１ａにより印刷領域６に絵柄、文字、図形、記号、番号などの輪転印刷画像部が印刷され、さらに輪転印刷見当マーク８ａが印刷される。一つの輪転印刷画像部で絵柄、文字、図形、記号、番号を構成してもよいし、複数の輪転印刷画像部を重ね合せて絵柄、文字、図形、記号、番号を構成してもよい。 Next, as in the first to first embodiments to the first to third embodiments described above, a rotary print image portion such as a pattern, a character, a figure, a symbol, or a number is printed on the printing area 6 by the plate cylinder 11a of the gravure printing unit. Further, a rotary printing register mark 8a is printed. The pattern, characters, figures, symbols, and numbers may be configured by one rotary print image portion, or the patterns, characters, graphics, symbols, and numbers may be configured by overlapping a plurality of rotary print image portions.
　その後、例えばグラビア印刷ユニット１０ａの版胴１１ａにより印刷された第１色目の輪転印刷見当マーク８ａと、参照マーク８１が見当マーク検出センサ１５ａにより検出される（Ｓ３）。 Then, for example, the first color rotary printing registration mark 8a printed by the plate cylinder 11a of the gravure printing unit 10a and the reference mark 81 are detected by the registration mark detection sensor 15a (S3).
　第１色目の輪転印刷見当マーク８ａと参照マーク８１との間の位置関係が設定範囲に入っていない場合、見当マーク検出センサ１５ａからの検出信号に基づいて、見当制御装置３０（図２参照）によりコンペンセータローラ１４ａが駆動されて見当マーク位置ずれが調整される。参照マークを使用する場合、輪転印刷見当マーク８ａと参照マーク８１の位置ずれを調整するときに、輪転印刷見当マーク８ａと参照マーク８１のどちらを基準見当マークとしてもよい。 When the positional relationship between the first color rotary printing registration mark 8a and the reference mark 81 is not within the set range, the registration control device 30 (see FIG. 2) based on the detection signal from the registration mark detection sensor 15a. Thus, the compensator roller 14a is driven to adjust the registration mark position deviation. When the reference mark is used, when adjusting the positional deviation between the rotary printing registration mark 8a and the reference mark 81, either the rotary printing registration mark 8a or the reference mark 81 may be used as the standard registration mark.
　他方、第１色目の輪転印刷見当マーク８ａと参照マーク８１との間の位置関係が設定範囲に入っている場合、見当マーク検出センサ１５ａからの検出信号に基づいて見当制御装置３０による調整は行なわれることはなく、見当マーク位置ずれ調整は終了する。 On the other hand, when the positional relationship between the first color rotary printing register mark 8a and the reference mark 81 is within the set range, adjustment by the register control device 30 is performed based on the detection signal from the register mark detection sensor 15a. The registration mark position deviation adjustment ends.
　さらに、輪転印刷見当マーク８ｂと、参照マーク８１が検出され、輪転印刷見当マーク８ｂと参照マーク８１との位置関係が設定範囲に入っていない場合、コンペンセータロール１４ｂが駆動されて見当マーク位置ずれが調整される。さらに、輪転印刷見当マーク８ｃと、参照マーク８１が検出され、輪転印刷見当マーク８ｃと参照マーク８１との位置関係が設定範囲に入っていない場合、コンペンセータロール１４ｃが駆動されて見当マーク位置ずれが調整される。なお、上述の例では、参照マーク８１を基準見当マークとして、輪転印刷見当マーク８ｂや輪転印刷見当マーク８ｃとの位置ずれを調整したが、輪転印刷見当マーク８ａを基準見当マークとして、輪転印刷見当マーク８ｂおよび輪転印刷見当マーク８ｃとの位置ずれを調整するようにしてもよい。 Further, when the rotary printing registration mark 8b and the reference mark 81 are detected and the positional relationship between the rotary printing registration mark 8b and the reference mark 81 is not within the set range, the compensator roll 14b is driven and the registration mark position shift is caused. Adjusted. Further, when the rotary printing registration mark 8c and the reference mark 81 are detected and the positional relationship between the rotary printing registration mark 8c and the reference mark 81 is not within the setting range, the compensator roll 14c is driven and the registration mark position shift is caused. Adjusted. In the above-described example, the reference mark 81 is used as a reference register mark, and the positional deviation from the rotary print register mark 8b and the rotary print register mark 8c is adjusted. However, the rotary print register is set using the rotary print register mark 8a as a reference register mark. You may make it adjust the position shift with the mark 8b and the rotary printing registration mark 8c.
　このように本実施の形態によれば、インクジェット印字装置４０の上流側に参照マーク付与部８４を設け、参照マーク付与部８４により形成された参照マーク８１を用いて、可変情報９と輪転印刷画像部との見当合わせを精度良く行うことができる。 As described above, according to the present embodiment, the reference mark providing unit 84 is provided on the upstream side of the ink jet printing apparatus 40, and the variable information 9 and the rotary print image are used by using the reference mark 81 formed by the reference mark providing unit 84. It is possible to perform registration with the part with high accuracy.
