現況技術、すなわち欧州特許第０ ８１２ ６８３ Ａ１号から、複数の印刷機構を備え、各印刷機構が、圧胴、圧胴上を転動するゴム胴、ゴム胴上を転動する版胴、ならびにインキング機構および湿潤機構を含む、オフセット印刷機が公知である。そこに開示されているオフセット印刷機では、印刷機構の圧胴、ゴム胴、インキング機構、ならびに湿潤機構が、駆動装置によって駆動される。これに対して、印刷機構の版胴には、版胴を印刷機の主駆動装置から切り離して内蔵モータで駆動する固有駆動装置ないし直接駆動装置が付随している。印刷機構が連続印刷状態にあるとき、印刷機構の圧胴、ゴム胴、インキング機構、ならびに湿潤機構は主駆動装置によって駆動され、これに対して印刷機構の版胴は、それぞれの直接駆動装置によって、主駆動装置と同期して駆動される。版胴を内蔵モータによって駆動するために、各版胴には、直接駆動装置の他に、連続印刷運転で対応する印刷機構のそれぞれのゴム胴と同期して、したがって印刷機の主駆動装置と同期して版胴を駆動する、調節装置が付随する。
欧州特許第０ ８１２ ６８３ 号公報 From the state of the art, ie EP 0 812 683 A1, with a plurality of printing mechanisms, each printing mechanism is a impression cylinder, a rubber cylinder rolling on the impression cylinder, a plate cylinder rolling on the rubber cylinder, and Offset printing presses are known that include an inking mechanism and a wetting mechanism. In the offset printing machine disclosed therein, an impression cylinder, a rubber cylinder, an inking mechanism, and a wetting mechanism of a printing mechanism are driven by a driving device. On the other hand, the plate cylinder of the printing mechanism is accompanied by a specific drive unit or a direct drive unit that is separated from the main drive unit of the printing press and driven by a built-in motor. When the printing mechanism is in a continuous printing state, the impression cylinder, rubber cylinder, inking mechanism, and wetting mechanism of the printing mechanism are driven by the main drive, whereas the plate cylinder of the printing mechanism has its own direct drive. Thus, it is driven in synchronism with the main drive device. In order to drive the plate cylinder by a built-in motor, each plate cylinder is synchronized with the respective rubber cylinder of the corresponding printing mechanism in the continuous printing operation in addition to the direct drive device, and thus the main drive device of the printing press. Accompanying is an adjustment device that drives the plate cylinder synchronously.
European Patent No. 0 812 683

上記に基づいて、本発明の課題は、新規の印刷機ならびにその動作方法を提供することにある。   Based on the above, an object of the present invention is to provide a novel printing press and an operation method thereof.

上記の課題は、請求項１に記載の印刷機によって達成される。本発明によれば、カラー印刷での複製誤差の補正を保証するため、カラー印刷に関与する各印刷機構において版胴用の位置目標値を形成するために、それぞれのゴム胴の位置現在値に、その入力値がそれぞれのゴム胴の位置現在値である重なり関数に基づいて決定可能な、補正量を重ねることが可能である。   The above object is achieved by a printing machine according to claim 1. According to the present invention, in order to guarantee correction of duplication error in color printing, in order to form a position target value for a plate cylinder in each printing mechanism involved in color printing, the current position value of each rubber cylinder is set to It is possible to overlap correction amounts that can be determined based on an overlap function whose input value is the current position value of each rubber cylinder.

本発明においては、カラー印刷における複製誤差は、カラー印刷に関与する印刷機構の版胴とそれぞれのゴム胴との間の巻き出し経路が変更されることによって補正することができる。それによって、印刷画像に複製誤差を補正する歪みを生ずることができる。複製誤差は、幾何的な誤差のことも、描画誤差のこともあり得る。   In the present invention, duplication errors in color printing can be corrected by changing the unwinding path between the plate cylinder of the printing mechanism involved in color printing and each rubber cylinder. As a result, distortion that corrects duplication errors can be generated in the printed image. The duplication error can be a geometric error or a drawing error.

本発明による印刷機の動作方法は、特許請求の範囲の独立請求項７に定義されている。   The operating method of the printing press according to the invention is defined in the independent claim 7.

本発明の好ましい変形形態は、従属請求項および以下の説明から明らかになる。図面を参照して本発明の例示的実施形態を、それだけに限定されるものではないが、詳細に説明する。   Preferred variants of the invention emerge from the dependent claims and the following description. Exemplary embodiments of the present invention will now be described in detail with reference to the drawings but are not limited thereto.

図１は本発明による印刷機の印刷機構１０の領域の断面図であり、図１に示した印刷機構１０は、圧胴１１と、圧胴１１上を転動するゴム胴１２と、ゴム胴１２上を転動する版胴１３と、版胴１３と連動し、印刷インキないし湿潤剤を版胴１３上に位置する刷版に展着する、図１には図示しないインキング機構および湿潤機構とを含んでいる。印刷インキは、版胴１３上に位置する刷版から出て、ゴム胴１２上に位置するゴムブランケット上に、続いて圧胴１１とゴム胴１２の間を通って移動する印刷材上に展着される。   FIG. 1 is a sectional view of an area of a printing mechanism 10 of a printing press according to the present invention. The printing mechanism 10 shown in FIG. 1 includes an impression cylinder 11, a rubber cylinder 12 that rolls on the impression cylinder 11, and a rubber cylinder. A printing cylinder 13 that rolls on the plate 12, and an inking mechanism and a wetting mechanism (not shown in FIG. 1) that spread printing ink or wetting agent on the printing plate located on the printing cylinder 13 in conjunction with the printing cylinder 13. Including. The printing ink emerges from the printing plate located on the plate cylinder 13 and is spread on the rubber blanket located on the rubber cylinder 12 and subsequently on the printing material moving between the impression cylinder 11 and the rubber cylinder 12. Worn.

枚葉紙の形態の印刷材の印刷に使用されるオフセット印刷機では、印刷材の移送方向に並べて配置され、好ましくは異なる印刷インキでの印刷材の印刷に使用される、複数のこの種の印刷機構１０を利用している。その際、隣接する印刷機構の間には、印刷材を印刷機構から印刷機構へと、したがって印刷機を縦断して移動させるために、少なくとも１つの移送胴１４が配置されている。図１は、そのような移送胴１４を示している。   In an offset printing machine used for printing a printing material in the form of a sheet of paper, a plurality of such types are arranged side by side in the printing material transport direction and are preferably used for printing the printing material with different printing inks. A printing mechanism 10 is used. In this case, at least one transfer cylinder 14 is arranged between the adjacent printing mechanisms in order to move the printing material from the printing mechanism to the printing mechanism and thus through the printing machine. FIG. 1 shows such a transfer cylinder 14.

本発明による印刷機では、印刷機の印刷機構１０の少なくとも圧胴１１およびゴム胴１２が印刷機の主駆動装置によって駆動される。これに対して版胴１３には直接駆動装置（図示せず）が付随しており、各版胴１３を、連続印刷状態のとき直接駆動装置によってゴム胴１２と同期して、したがって主駆動装置と同期して駆動することができる。そのために版胴１３の各直接駆動装置には、版胴１３の位置現在値１７と版胴１３の位置目標値１８の調節差１６に基づいて版胴１３用の調節信号１９を生成する調節装置１５が付随している。   In the printing press according to the present invention, at least the impression cylinder 11 and the rubber cylinder 12 of the printing mechanism 10 of the printing press are driven by the main drive device of the printing press. On the other hand, the plate cylinder 13 is accompanied by a direct drive device (not shown), and each plate cylinder 13 is synchronized with the rubber cylinder 12 by the direct drive device in the continuous printing state, and thus the main drive device. Can be driven in synchronization with For this purpose, each direct drive device of the plate cylinder 13 has an adjustment device for generating an adjustment signal 19 for the plate cylinder 13 based on the adjustment difference 16 between the current position value 17 of the plate cylinder 13 and the position target value 18 of the plate cylinder 13. 15 is attached.

版胴１３がゴム胴１２と同期して駆動される必要がある連続印刷状態では、版胴１３の位置目標値１８は、ゴム胴１２の位置現在値２０によって形成される。   In a continuous printing state in which the plate cylinder 13 needs to be driven in synchronization with the rubber cylinder 12, the position target value 18 of the plate cylinder 13 is formed by the current position value 20 of the rubber cylinder 12.

カラー印刷では、すなわち例えば異なる印刷機構１０を用いてシアン、マゼンタ、黄色、および黒の印刷インキの部分印刷画像が印刷材に展着されるオートティピカル多色印刷では、複製誤差によって、カラー印刷により作製される印刷結果に歪みが形成されることがある。複製誤差の補正を保証するため、本発明によってカラー印刷に関与する少なくとも１つのまたは各々の印刷機構１０で版胴１３用の位置目標値１８を形成するために、それぞれのゴム胴１２の位置現在値２０に補正量２１を重ねることが提案される。補正量２１は重なり関数２２に基づいて決定され、重なり関数２２の入力値はそれぞれのゴム胴１２の位置現在値２０である。それぞれのゴム胴１２の位置現在値２０に重ねられる補正量２１により、カラー印刷での複製誤差を補正ないし補償するために、それぞれの印刷機構１０ のゴム胴１２に対する版胴１３の巻き出し経路を変更することができる。   In color printing, that is, in automatic multicolor printing in which, for example, partial printing images of cyan, magenta, yellow, and black printing inks are spread on a printing material using different printing mechanisms 10, due to duplication errors, color printing Distortion may be formed in the produced printing result. In order to guarantee correction of duplication errors, the present position of each rubber cylinder 12 is used to form a position target value 18 for the plate cylinder 13 in at least one or each printing mechanism 10 involved in color printing according to the present invention. It is proposed to superimpose the correction amount 21 on the value 20. The correction amount 21 is determined based on the overlap function 22, and the input value of the overlap function 22 is the current position value 20 of each rubber cylinder 12. In order to correct or compensate for duplication errors in color printing by the correction amount 21 superimposed on the current position 20 of each rubber cylinder 12, the unwinding path of the plate cylinder 13 to the rubber cylinder 12 of each printing mechanism 10 is provided. Can be changed.

図２および３は、補正量２１を決定するための重なり関数２２ａおよび２２ｂの２つの例示的実施形態をそれぞれ示しており、図２および３の重なり関数２２ａおよび２２ｂは図示の方法が異なるだけである。すなわち、図２では横軸に印刷機構のゴム胴の位置現在値２０が、また縦軸に対応する版胴１３の位置現在値１７とゴム胴１２ の位置現在値２０の差△が記されている。これに対して図３では、横軸にゴム胴１２の位置現在値２０が、また縦軸には版胴１３の位置現在値１７が記されている。重なり関数は、版胴とゴム胴の位置現在値の所望の差を定義する。   FIGS. 2 and 3 show two exemplary embodiments of overlap functions 22a and 22b, respectively, for determining the correction amount 21, and the overlap functions 22a and 22b of FIGS. 2 and 3 differ only in the manner shown. is there. That is, in FIG. 2, the horizontal axis indicates the current position 20 of the rubber cylinder of the printing mechanism, and the vertical axis indicates the difference Δ between the current position 17 of the plate cylinder 13 and the current position 20 of the rubber cylinder 12 corresponding to the vertical axis. Yes. On the other hand, in FIG. 3, the current position 20 of the rubber cylinder 12 is shown on the horizontal axis, and the current position 17 of the plate cylinder 13 is shown on the vertical axis. The overlap function defines the desired difference between the current position values of the plate cylinder and the rubber cylinder.

どちらの重なり関数２２ａおよび２２ｂでも、図２および３によれば、ゴム胴１２の位置現在値２０が印刷始点ＤＡに対応する場合、版胴１３の位置現在値１７とゴム胴１２の位置現在値２０の差はゼロである。ゴム胴１２の位置現在値２０が印刷始点ＤＡと印刷終点ＤＥの間にある場合、版胴１３の位置現在値１７とゴム胴１２の位置現在値２０の差は、ゼロとは異なる値である。ゴム胴１２の位置現在値２０が印刷始点ＤＡと印刷終点ＤＥの間にある場合、対応する印刷機構で印刷される。これに対して、ゴム胴１２の位置現在値２０が印刷終点ＤＥと印刷始点ＤＡの間にある場合は、この位置現在値２０がゴム胴１２の緊張チャネルに対応するので、印刷されない。   In both overlap functions 22a and 22b, according to FIGS. 2 and 3, when the current position value 20 of the rubber cylinder 12 corresponds to the printing start point DA, the current position value 17 of the plate cylinder 13 and the current position value of the rubber cylinder 12 are used. The difference of 20 is zero. When the current position value 20 of the rubber cylinder 12 is between the printing start point DA and the printing end point DE, the difference between the current position value 17 of the plate cylinder 13 and the current position value 20 of the rubber cylinder 12 is a value different from zero. . When the current position value 20 of the rubber cylinder 12 is between the printing start point DA and the printing end point DE, printing is performed by the corresponding printing mechanism. On the other hand, when the current position value 20 of the rubber cylinder 12 is between the printing end point DE and the printing start point DA, the current position value 20 corresponds to the tension channel of the rubber cylinder 12 and is not printed.

図２および３の例示的実施形態では、重なり関数２２ａ、２２ｂは、印刷始点ＤＡではゼロであるゴム胴１２および版胴１３の位置現在値２０と１７の差の他に、別の２つの基準点によって、すなわち印刷の中間点ＤＭの領域の基準点ならびに印刷終点ＤＥの領域の基準点によって決定される。これらの基準点に対して、それぞれの印刷機構１０の版胴１３および対応するゴム胴１２の位置現在値１７と２０のそれぞれの差２３ａ、２４ａないし２３ｂ、２４ｂが設定される。基準点ＤＡ、ＤＭおよびＤＥの間にあるゴム胴１２の位置現在値２０については、版胴１３の位置現在値１７とゴム胴１２の位置現在値２０のそれぞれの差が線形補間によって決定される。   In the exemplary embodiment of FIGS. 2 and 3, the overlap functions 22a, 22b are two other criteria in addition to the difference between the current position values 20 and 17 of the rubber cylinder 12 and the plate cylinder 13 which are zero at the printing start point DA. It is determined by the point, that is by the reference point in the area of the printing intermediate point DM and the reference point in the area of the printing end point DE. Differences 23a, 24a to 23b, 24b of the current position values 17 and 20 of the plate cylinder 13 of each printing mechanism 10 and the corresponding rubber cylinder 12 are set for these reference points. For the current position value 20 of the rubber cylinder 12 between the reference points DA, DM and DE, the difference between the current position value 17 of the plate cylinder 13 and the current position value 20 of the rubber cylinder 12 is determined by linear interpolation. .

重なり関数２２ａは、印刷始点ＤＡと印刷終点ＤＥの間の全印刷領域で、版胴１３の位置現在値１７とゴム胴１２の位置現在値２０の差がゼロより大きい、すなわち正であり、それによって印刷画像の延長が可能であることを特徴としている。   The overlap function 22a is the difference between the current position value 17 of the plate cylinder 13 and the current position value 20 of the rubber cylinder 12 is greater than zero in the entire printing area between the printing start point DA and the printing end point DE. The feature is that the print image can be extended.

これに対して重なり関数２２ｂでは、この差は印刷始点ＤＡと印刷終点ＤＥの間の全領域で負であり、それによって印刷画像の短縮を実現することができる。   On the other hand, in the overlap function 22b, this difference is negative in the entire area between the print start point DA and the print end point DE, thereby realizing a shortened print image.

重なり関数２２ａの場合は、版胴１３およびゴム胴１２の現在値１７と２０の差は印刷の中間点ＤＭと印刷終点ＤＥの両方の基準点で同じであり、その結果、両方の基準点ＤＭとＤＥの間の上記の差は一定である。印刷始点ＤＡと印刷の中間点ＤＭの間では、この差は印刷始点ＤＡ時のゼロの値から始まって、印刷の中間点ＤＭでこの基準点に設定された値になるまで連続的に増大する。これに対して重なり関数２２ｂでは、版胴１３およびゴム胴１２の位置現在値１７、２０の差が印刷始点ＤＡと印刷終点の間で連続的に増大することを確認されたい。   In the case of the overlap function 22a, the difference between the current values 17 and 20 of the plate cylinder 13 and the rubber cylinder 12 is the same at the reference point of both the printing intermediate point DM and the printing end point DE, and as a result, both reference points DM. The above difference between DE and DE is constant. Between the printing start point DA and the printing intermediate point DM, this difference starts from a zero value at the printing starting point DA and continuously increases until the printing intermediate point DM reaches the value set for this reference point. . On the other hand, in the overlap function 22b, it should be confirmed that the difference between the current position values 17 and 20 of the plate cylinder 13 and the rubber cylinder 12 continuously increases between the printing start point DA and the printing end point.

重なり関数用の基準点の上記の数は単なる例に過ぎない。したがって、重なり関数用の基準点の数、ならびにこれらの基準点での版胴１３およびゴム胴１２の位置現在値１７と２０の差の量は、オペレータによって自由に定義され、あるいは自由に選択される。   The above numbers of reference points for the overlap function are merely examples. Accordingly, the number of reference points for the overlap function and the amount of difference between the current position values 17 and 20 of the plate cylinder 13 and the rubber cylinder 12 at these reference points are freely defined or freely selected by the operator. The

カラー印刷に関与する印刷機構に対する重なり関数は、事前に定義しておいて、制御の意味で補正量を決定するために使用することができ、また調節の意味で重なる補正量を決定するためにカラー印刷時に印刷される印刷パターンを把握し評価することも可能である。さらに、適応調節の意味で重なり関数がカラー印刷中に連続的に適応されないしは修正されるようにすることもできる。   The overlap function for the printing mechanism involved in color printing can be defined in advance and used to determine the correction amount in the sense of control, and also to determine the correction amount that overlaps in the sense of adjustment It is also possible to grasp and evaluate a print pattern printed during color printing. Furthermore, in the sense of adaptive adjustment, the overlap function can be continuously adapted or modified during color printing.
