套版控制之方法及裝置 Method and device for controlling plate

本發明，係有關供利用多色凹版印刷機、多色平版印刷機等的多色印刷機下的印刷的色偏差防止用的套版控制之方法及裝置。 The present invention relates to a method and apparatus for pattern control for preventing color deviation prevention in printing under a multicolor printer such as a multicolor gravure printing machine or a multicolor lithographic printing machine.

利用多色凹版印刷機，而藉分配不同色的複數個印版滾筒，對紙、膜等的捲筒紙以疊印印刷圖樣的情況下，在印版滾筒產生旋轉偏差或在捲筒紙發生伸長、收縮等時，在最後獲得的圖樣會產生色偏差。 By using a multi-color gravure printing machine, by distributing a plurality of plate cylinders of different colors, in the case of overprinting a printing paper of paper, film, etc., a rotation deviation occurs in the plate cylinder or elongation occurs in the web. When shrinking, etc., the pattern obtained at the end will produce a color deviation.

所以，為了防止此色偏差的發生，在藉該印版滾筒將特定的色的圖樣印刷於捲筒紙時，同時於各印版滾筒實施在該捲筒紙的空白部印刷同色的校排記號，藉此進行在捲筒紙上排列複數個校排記號的印刷。並且，針對該等複數個校排記號的相互間之間距作檢測而求出色偏差的有無、程度等，基於所得的結果，而進行供於防止發生色偏差用的套版控制。 Therefore, in order to prevent the occurrence of the color deviation, when the pattern of the specific color is printed on the roll paper by the plate cylinder, the calibration marks of the same color are printed on the blank portion of the roll paper at the same time for each plate cylinder. Thereby, printing of a plurality of calibration symbols is arranged on the web. Then, the presence or absence of the color deviation, the degree, and the like are determined for the distance between the plurality of calibration symbols, and based on the obtained result, the registration control for preventing color deviation is performed.

In the aspect of the vertical plate control, the two calibration sensors printed on the two adjacent plate cylinders are detected by two photo sensors during the effective period of the gating signal to detect the 2 The distance between the same edges of the calibration marks becomes a predetermined value, adjusting the rotation phase of the downstream plate cylinder measured among the adjacent two plate cylinders, or adjusting between the adjacent two plate cylinders The path of the web is long, thereby correcting the color deviation of the transport direction. In addition, in the aspect of the horizontal plate control, the plate cylinder of the downstream measurement among the two adjacent plate cylinders is performed in such a manner that the distance between the same edges of the two calibration symbols is determined to be a predetermined value. The offset in the direction of the rotation axis is adjusted, and the color deviation in the direction orthogonal to the conveyance direction is corrected.

各掃描頭9B~9D，係依在印刷於捲筒紙4的前述之2個校排記號到來的時機成為有效的閘控信號，取進其檢測信號。使用如此之閘控信號，係由於印刷於捲筒紙4的校排記號於該捲筒紙4的端部的空白部分排成一行而最後變成印刷4個，故為了作成可正確選擇其中的作為目的之2個校排記號。 Each of the scanning heads 9B to 9D is an effective gate signal at the timing when the two preceding calibration marks printed on the roll paper 4 come, and the detection signal is taken in. By using such a gate control signal, since the alignment marks printed on the roll paper 4 are lined up in the blank portion of the end portion of the roll paper 4, and finally four prints are made, the correct one can be selected for creation. 2 school row marks for the purpose.

Encoders 11A, 11B, 11C, and 11D are attached to the rotation shafts of the servo motors 10A to 10D, and the encoders 11A to 11D detect the rotational phases of the servo motors 10A to 10D, respectively.

套版控制裝置12係具備中央處理裝置(CPU)，儲存著運轉用的程式、各印版滾筒5A~5D的直徑、各壓印滾筒6A~6D的直徑、各檢測頭8A~8D的安裝位置、對應的印版滾筒的印刷點間的路徑長其他各種的資料。並且，基於掃描頭9B~9D的檢測結果而調整印版滾筒5B~5D的相位以外，進行印版滾筒2A~2D的相互間的相位差的設定及閘控信號的產生時機的設定。在此 The registration control device 12 includes a central processing unit (CPU) that stores a program for operation, a diameter of each of the plate cylinders 5A to 5D, a diameter of each of the impression cylinders 6A to 6D, and a mounting position of each of the detection heads 8A to 8D.

Further, the plate control device 12 controls the servo motors 10A to 10D via the line S4.

在圖7示出印刷於捲筒紙4的縱套版控制用的校排記號7A~7D。示於(a)行的各校排記號7A~7D，係正規(例如20mm)地印刷間距H1。此係表式各色的圖樣正常地印刷於捲筒紙4。相對於此，示於(b)行的各校排記號7A~7D，係校排記號7D(黑色)方面，在捲筒紙4的搬送方向X的方向上發生距離d1的偏差。此係表示在黑色的圖樣方面，在捲筒紙4的搬送方向X的方向上發生距離d1的偏差。 The alignment symbols 7A to 7D for vertical plate printing printed on the roll paper 4 are shown in Fig. 7 . Each of the calibration marks 7A to 7D shown in the row (a) is a regular (for example, 20 mm) printing pitch H1. The patterns of the various colors are normally printed on the web 4. On the other hand, in each of the alignment marks 7A to 7D shown in the (b) row, the alignment symbol 7D (black) indicates a deviation of the distance d1 in the direction of the transport direction X of the roll paper 4. This indicates that the deviation of the distance d1 occurs in the direction of the transport direction X of the roll paper 4 in terms of the black pattern.

如此之情況下，對校排記號7D的相對於校排記號7C的相對位置作監視，使得可檢測出黑色的圖樣的偏差的距離d1，以該距離d1成為0的方式執行控制伺服馬達10D而調整印版滾筒5D的旋轉相位的縱套版控制。 In this case, the relative position of the calibration symbol 7D with respect to the calibration symbol 7C is monitored so that the distance d1 of the deviation of the black pattern can be detected, and the servo motor 10D is controlled such that the distance d1 becomes zero. Vertical plate control for adjusting the rotational phase of the plate cylinder 5D.

如上所述，為了縱套版控制，係需要檢測出以相鄰之印版滾筒而印刷的2個校排記號之間距，在供於此檢測用的掃描頭9B~9D方面，係採用分別具備光照射接收器的2個光感測器。 As described above, in order to control the vertical plate, it is necessary to detect the distance between the two calibration marks printed by the adjacent plate cylinders, and the scanning heads 9B to 9D for the detection are respectively provided. The light illuminates the two light sensors of the receiver.

以掃描頭9D為代表而示於圖8。在掃描頭9D，係在捲筒紙4的搬送方向X的上游側配置光感測器91，在下游測配置光感測器92。光感測器91、92，係為了檢測出藉印版滾筒5C而印刷的校排記號7C與藉印版 滾筒5D而印刷的校排記號7D之間距，在該校排記號7C、7D上的點光之間距被配置成符合校排記號7C、7D之間距H1的正規值。 This is shown in Fig. 8 with the scanning head 9D as a representative. In the scanning head 9D, the photo sensor 91 is disposed on the upstream side of the transport direction X of the roll paper 4, and the photo sensor 92 is placed downstream. The photo sensors 91 and 92 are used to detect the registration mark 7C and the borrowed printing plate printed by the plate cylinder 5C. The distance between the alignment marks 7D printed by the drum 5D and the spot light on the alignment marks 7C and 7D are arranged to conform to the normal value of the distance H1 between the alignment marks 7C and 7D.

於圖9繪示檢測出的波形圖。於圖9，7A1、7B1、7C1、7D1係以光感測器91、92檢測出校排記號7A~7D的檢測信號V91、V92的檢測脈衝。配置在捲筒紙4的上游側的光感測器91檢測出校排記號7D的檢測脈衝7D1的前邊緣的時機、及配置於下游測的光感測器92檢測出校排記號7C的檢測脈衝7C1的前邊緣的時機一致時，表示：兩校排記號7C、7D之間距H1為正規值，印版滾筒5D係旋轉相位差相對於印版滾筒5C成為零。 The detected waveform is shown in FIG. In Figs. 9, 7A1, 7B1, 7C1, and 7D1 detect the detection pulses of the detection signals V91 and V92 of the alignment marks 7A to 7D by the photo sensors 91 and 92. The timing at which the photo sensor 91 disposed on the upstream side of the roll paper 4 detects the front edge of the detection pulse 7D1 of the calibration mark 7D, and the photo sensor 92 disposed downstream detects the detection of the calibration mark 7C. When the timing of the leading edge of the pulse 7C1 coincides, it means that the distance H1 between the two alignment marks 7C and 7D is a normal value, and the rotational phase difference of the plate cylinder 5D becomes zero with respect to the plate cylinder 5C.

然而，如示於圖9，以光感測器91檢測出的校排記號7D的檢測脈衝7D1的前邊緣的檢測時機，比以光感測器92檢測出的校排記號7C的檢測脈衝7C1的前邊緣的時機前進時間T1時，表示校排記號7C與7D之間距H1比正規值小(圖7的(b)中係短d1)，印刷了校排記號7D的印版滾筒7D的旋轉相位前進T1。此情況下，係進行以使印版滾筒5D的旋轉相位延遲T1的方式控制伺服馬達10D的縱套版控制。 However, as shown in FIG. 9, the detection timing of the leading edge of the detection pulse 7D1 of the calibration symbol 7D detected by the photo sensor 91 is higher than the detection pulse 7C1 of the calibration symbol 7C detected by the photo sensor 92. When the timing advance time T1 of the leading edge indicates that the distance H1 between the alignment marks 7C and 7D is smaller than the normal value (short d1 in (b) of FIG. 7), the rotation of the plate cylinder 7D on which the calibration symbol 7D is printed is printed. The phase advances to T1. In this case, the vertical plate control of the servo motor 10D is controlled such that the rotational phase of the plate cylinder 5D is delayed by T1.

反之，光感測器91所檢測出的校排記號7D的檢測脈衝7D1的前邊緣的時機，比光感測器92所檢測出的校排記號7C的檢測脈衝7C1的前邊緣的檢測時機延遲時，表示：校排記號7C與7D之間距H1比正規值大，印刷了校排記號7D的印版滾筒5D的旋轉相位延遲該程 度。此情況下，係進行以使印版滾筒5D的旋轉相位前進的方式控制伺服馬達10D的縱套版控制。校排記號7A與7B之間之間距、校排記號7B與7C之間之間距方面，亦同樣地作檢測而進行同樣的縱套版控制。 On the other hand, the timing of the front edge of the detection pulse 7D1 of the calibration symbol 7D detected by the photo sensor 91 is delayed from the detection timing of the front edge of the detection pulse 7C1 of the calibration symbol 7C detected by the photo sensor 92. When it is indicated that the distance H1 between the calibration marks 7C and 7D is larger than the normal value, the rotation phase of the plate cylinder 5D printed with the calibration mark 7D is delayed. degree. In this case, the vertical plate control of the servo motor 10D is controlled so that the rotational phase of the plate cylinder 5D advances. The same vertical plate control is also performed for the detection of the distance between the alignment marks 7A and 7B and the distance between the alignment marks 7B and 7C.

另外，從掃描頭9D的光感測器91、92，使該檢測輸出維持不變時，如示於圖9，不僅校排記號7C與7D的檢測脈衝7C1、7D1，亦會輸出校排記號7A、7B的檢測脈衝7A1、7B1。所以，為了選擇適合使用於當下的縱套版控制的檢測脈衝7C1、7D1，而使用閘控信號Vgate_D。 Further, when the detection outputs are maintained from the photo sensors 91 and 92 of the scanning head 9D, as shown in FIG. 9, not only the detection pulses 7C1 and 7D1 of the alignment marks 7C and 7D but also the calibration marks are output. Detection pulses 7A1, 7B1 of 7A, 7B. Therefore, in order to select the detection pulses 7C1, 7D1 suitable for use in the current vertical plate control, the gate signal Vgate_D is used.

此閘控信號Vgate_D，係以僅檢測出校排記號7C、7D的檢測脈衝7C1、7D1的方式，而設定可作該檢測的有效期間T0。此閘控信號Vgate_D的有效期間T0，係一般而言，設定成對應於校排記號7C與7D之間距H1的正規值的時間。 The gate control signal Vgate_D sets the effective period T0 at which the detection can be performed by detecting only the detection pulses 7C1 and 7D1 of the calibration symbols 7C and 7D. The effective period T0 of the gate control signal Vgate_D is generally set to a time corresponding to the normal value of the distance H1 between the alignment marks 7C and 7D.

此閘控信號Vgate_D的時機的設定，係於多色凹版印刷裝置進入正式印刷以前的進行縱套版控制的調整印刷的階段，檢測出校排記號7A~7D，而自動或操作員確認該檢測波形下，以相鄰之印版滾筒而印刷的2個校排記號落入有效期間T0內的方式而進行。作成如此而設定的閘控信號Vgate_D的有效期間T0的時機，係通常，進入正式印刷後不會變更。 The timing of the gate control signal Vgate_D is set at the stage of the adjustment printing of the vertical plate control before the multi-color gravure printing device enters the formal printing, and the calibration symbols 7A to 7D are detected, and the automatic or operator confirms the detection. In the waveform, the two calibration symbols printed by the adjacent plate cylinders fall within the effective period T0. The timing of the effective period T0 of the gate signal Vgate_D set as described above is normally not changed after the official printing is entered.

然而，在進入正式印刷前進行縱套版控制的印刷調整係在低速印刷下進行，惟進入正式印刷而印刷產品時係變成高速印刷，故在閘控信號的所設定的有效期間T0的時機方面，有時發生偏差。並且，如此在閘控信號的有效期間T0的時機方面發生偏差下直接繼續印刷時，如示於圖10，例如校排記號7D的檢測脈衝7D1從閘控信號Vgate_D的有效期間內偏離，而發生變成不須控制的事態。 However, the printing adjustment for the vertical plate control before the official printing is performed under the low speed printing, but the printing is changed to the high speed printing when the printing is performed, so the timing of the set effective period T0 of the gating signal is Sometimes deviations occur. Further, when the printing is directly continued with a deviation in the timing of the effective period T0 of the gate signal, as shown in FIG. 10, for example, the detection pulse 7D1 of the calibration symbol 7D deviates from the effective period of the gate signal Vgate_D, and occurs. It becomes a state of affairs that does not require control.

所以，操作員，係為了防範如此之事態發生於未然，而不得不以正式印刷的運轉中2個校排記號必定落入閘控信號的有效期間T0的大致中央的方式，而於監控畫面中不斷監視。 Therefore, in order to prevent such a situation from happening, the operator has to enter the approximate center of the effective period T0 of the gate control signal in the operation of the official printing, and in the monitoring screen.

在圖1例示套版控制中的掃描頭9D用的閘控信號作成的樣子。P1係以針對將印版滾筒5D作旋轉驅動的伺服馬達10D的旋轉進行檢測的編碼器11D而產生的Z相脈衝，印版滾筒5D的旋轉每1圈產生1個脈衝。P2係以該編碼器11D而產生的A相脈衝，印版滾筒5D的旋轉每1圈產生1000個脈衝。 The gate control signal for the scanning head 9D in the plate control is illustrated in Fig. 1 . P1 is a Z-phase pulse generated by the encoder 11D for detecting the rotation of the servo motor 10D that rotationally drives the plate cylinder 5D, and the rotation of the plate cylinder 5D generates one pulse per revolution. P2 is an A-phase pulse generated by the encoder 11D, and the rotation of the plate cylinder 5D generates 1000 pulses per one turn.

掃描頭8D用的閘控信號Vgate_D的有效期間T0，係設定成：使藉內建於套版控制裝置12或利用CPU而構成的計數器，從Z相脈衝P1至A相脈衝P2計數n1的時刻為前邊緣，使從該時刻針對A相脈衝P2計數n2(>n1)的時刻為後邊緣。 The effective period T0 of the gate control signal Vgate_D for the scan head 8D is set such that the counter built by the registration control device 12 or the CPU is used to count n1 from the Z-phase pulse P1 to the A-phase pulse P2. For the front edge, the time at which n2 (>n1) is counted for the A-phase pulse P2 from this time is the trailing edge.

印版滾筒5D的周長為500mm的情況下，A相脈衝P2的每1個的距離係0.5mm，故以校排記號之間距H1為正規的20mm而印刷的情況下，有效期間T0的A相脈衝P2的脈衝數(n2-n1)，係成為40個。 When the circumferential length of the plate cylinder 5D is 500 mm, the distance of each of the A-phase pulses P2 is 0.5 mm. Therefore, when the distance between the alignment marks H1 is 20 mm and the printing is performed, the effective period T0 is A. The number of pulses (n2-n1) of the phase pulse P2 is 40.

在本實施例，係針對以掃描頭8D的光感測器92而檢測出的校排記號7C的檢測脈衝7C1在掃描頭8D用的閘控信號Vgate_D的有效期間T0之中的何位置進行檢測，而使閘控信號Vgate_D的有效期間T0時間偏移成該檢測脈衝7C1位於中央附近。此處非以下游的印版滾筒 5D而印刷的校排記號7D的檢測脈衝7D1，而使用以上游的印版滾筒5C而印刷的校排記號7C的檢測脈衝7C1，係因為：以校排記號7C為基準檢測出校排記號7D的偏差量，而控制印版滾筒5D的相位。 In the present embodiment, the position of the detection pulse 7C1 of the calibration mark 7C detected by the photo sensor 92 of the scan head 8D is detected in the effective period T0 of the gating signal Vgate_D for the scan head 8D. The effective period T0 of the gate control signal Vgate_D is time shifted so that the detection pulse 7C1 is located near the center. Here is not the downstream plate cylinder The detection pulse 7D1 of the calibration symbol 7D printed in 5D is used, and the detection pulse 7C1 of the calibration symbol 7C printed by the upstream plate cylinder 5C is used because the calibration symbol 7D is detected based on the calibration symbol 7C. The amount of deviation, while controlling the phase of the plate cylinder 5D.

如示於圖2、圖3，針對編碼器11D的A相脈衝P2的個數，作為n1取得閘控信號Vgate_D的前邊緣的時機後，作為n3取得檢測脈衝7C1的前邊緣的時機(ST1)，作為n4取得檢測脈衝7C1的後邊緣的時機(ST2)。並且，藉(n4-n3)/2=n5的演算，算出閘控信號Vgate_D的中間點的A相脈衝P2的個數n5(ST3)。 2 and 3, the timing of obtaining the front edge of the detection pulse 7C1 as n3 after the timing of acquiring the front edge of the gate signal Vgate_D as n1 for the number of the A-phase pulses P2 of the encoder 11D (ST1) The timing of the trailing edge of the detection pulse 7C1 is obtained as n4 (ST2). Then, the number n5 of the A-phase pulse P2 at the intermediate point of the gate signal Vgate_D is calculated by the calculation of (n4-n3)/2=n5 (ST3).

接著，閘控信號Vgate_D的有效期間T0係相當於「n2-n1」，故藉n5-(n2-n1)/2=n6，算出作為目的之偏移後的新閘控信號Vgate_D1的前邊緣的A相脈衝P2的個數n6(ST4)。再者，藉n5+(n2-n1)/2=n7，算出新閘控信號Vgate_D1的後邊緣的A相脈衝P2的個數n7(ST5)。 Next, the effective period T0 of the gate control signal Vgate_D is equivalent to "n2-n1", so the front edge of the new gate signal Vgate_D1 after the target offset is calculated by n5-(n2-n1)/2=n6. The number of phase A pulses P2 is n6 (ST4). Further, by n5+(n2-n1)/2=n7, the number n7 of the A-phase pulses P2 at the trailing edge of the new gate signal Vgate_D1 is calculated (ST5).

藉進行以上的處理，新閘控信號Vgate_D1，係變成校排記號7C的檢測脈衝7C1自動位於該有效期間T0的中央附近。為此，相對於以上游的印版滾筒5C而印刷的校排記號7C，以下游的印版滾筒5D而印刷的校排記號7D在上游方向或下游方向的任一方向上產生偏差的情況下，只要該偏差量在既定的範圍內，即可使校排記號7D留在新閘控信號Vgate_D1的有效期間T0內。 By the above processing, the new gate control signal Vgate_D1, which is the detection pulse 7C1 of the calibration symbol 7C, is automatically located near the center of the effective period T0. For this reason, in the case where the correction symbol 7C printed by the upstream plate cylinder 5C is offset in any of the upstream direction or the downstream direction with respect to the calibration mark 7D printed by the downstream plate cylinder 5C, As long as the deviation amount is within the predetermined range, the calibration symbol 7D can be left in the valid period T0 of the new gate signal Vgate_D1.

另外，在以上係使用以上游的印版滾筒5C而 印刷的校排記號7C的檢測脈衝7C1，而以該檢測脈衝7C1位於新閘控信號Vgate_D1的中央附近的方式，針對該新閘控信號Vgate_D1的有效期間T0的時機進行調整。然而，在一般的動作判明校排記號7C與7D的偏差不太大的情況下，係亦可利用以下游測的印版滾筒5D而印刷的校排記號7D的檢測脈衝7D1，而同樣地針對下游測的新閘控信號Vgate_D1的有效期間T0的時機進行調整。 In addition, in the above, the plate cylinder 5C upstream is used. The detected pulse 7C1 of the printed symbol 7C is adjusted, and the timing of the effective period T0 of the new gate signal Vgate_D1 is adjusted so that the detection pulse 7C1 is located near the center of the new gate signal Vgate_D1. However, in the case where the general operation indicates that the deviation between the correction marks 7C and 7D is not too large, the detection pulse 7D1 of the calibration symbol 7D printed by the plate cylinder 5D measured downstream can be used, and the same applies to The timing of the effective period T0 of the new gate control signal Vgate_D1 measured downstream is adjusted.

此外，在以上係雖在校排記號7A~7D方面使用長方形的形狀者，惟此係供於針對沿著捲筒紙4的搬送方向X的方向(縱向)上的色偏差進行修正用的縱套版控制用的校排記號。 In addition, in the above, the rectangular shape is used for the alignment marks 7A to 7D, and the vertical shape is used for correcting the color deviation in the direction (longitudinal direction) along the conveyance direction X of the roll paper 4. The calibration symbol for the set control.

然而，如前所述，在多色凹版印刷機，係不僅需要縱套版控制的縱向的色偏差，亦會發生需要橫套版控制的因正交於搬送方向X的方向(寬度方向)上的偏差而起的色偏差。在對於此橫向的色偏差的橫套版控制，係依該偏差量而進行使該印版滾筒本身於該軸向上偏位的控制。 However, as described above, in the multi-color gravure printing machine, not only the longitudinal color deviation of the vertical plate control but also the direction (width direction) orthogonal to the conveyance direction X which requires the horizontal plate control is required. The color deviation caused by the deviation. In the horizontal plate control for the lateral color deviation, the control for biasing the plate cylinder itself in the axial direction is performed in accordance with the amount of deviation.

在同時進行如此之縱套版控制與橫套版控制的情況下，係使如示於圖4之三角狀的校排記號7A’、7B’、7C’、7D’，藉各印版滾筒5A~5D而印刷於捲筒紙4的空白。此校排記號7A’~7D’，係具有相對於平行於捲筒紙4的搬送方向X地配置2個光感測器的掃描頭8B~8D的掃描線L1而正交的縱套版控制用邊緣7a、及傾斜之橫套版控制用邊緣7b。 In the case where such vertical plate control and horizontal plate control are simultaneously performed, the triangular-shaped alignment marks 7A', 7B', 7C', and 7D' as shown in FIG. 4 are used to borrow the plate cylinders 5A. ~5D is printed on the blank of the roll paper 4. This alignment number 7A' to 7D' is a vertical plate control having orthogonal to the scanning line L1 of the scanning heads 8B to 8D in which two photosensors are arranged in parallel with the transport direction X of the roll paper 4. The edge 7b is controlled by the edge 7a and the inclined transverse plate.

使用此校排記號7A’~7D’之情況下，係以各校排記號7A’~7D’的縱套版控制用邊緣7a之間距H1成為正規值的方式進行控制，使得可進行沿著捲筒紙4的搬送方向X的方向上的縱套版控制。此外，各校排記號7A’~7D’係正交於捲筒紙4的搬送方向X的方向上發生偏差時在橫套版控制用邊緣7b之間距H2產生偏差，故以該間距H2成為正規值的方式作控制，使得可進行正交於捲筒紙4的搬送方向X的方向上的橫套版控制。 When the alignment symbol 7A' to 7D' is used, the vertical plate control edge 7a of each of the alignment marks 7A' to 7D' is controlled so that the distance H1 becomes a normal value, so that the roll can be performed along the roll. Vertical plate control in the direction of the transport direction X of the roll paper 4. Further, when the respective row numbers 7A' to 7D' are orthogonal to each other in the direction of the transport direction X of the roll paper 4, the distance between the horizontal plate control edges 7b varies from H2, so that the pitch H2 becomes regular. The manner of the value is controlled such that the transverse plate control in the direction orthogonal to the transport direction X of the roll paper 4 can be performed.

所以，以掃描頭8D檢測校排記號7C’與7D’而進行縱套版控制與橫套版控制時，係根據從該校排記號7C’的檢測脈衝之中的前端的縱套版控制用邊緣7a的檢測時機至後端的橫套版控制用邊緣7b的檢測時機為止的時間經過，檢測出該校排記號7C’的檢測脈衝的中央附近的檢測時機，以該校排記號7C’的檢測脈衝位於新閘控信號Vgate_D1的有效期間T0的中央附近的方式，而針對該新閘控信號Vgate_D1的有效期間T0的時機進行調整。 Therefore, when the scanning head 8D detects the alignment symbols 7C' and 7D' and performs the vertical plate control and the horizontal plate control, it is based on the vertical plate control of the front end among the detection pulses from the calibration mark 7C'. The detection time from the detection timing of the edge 7a to the detection timing of the horizontal registration edge 7b of the rear end detects the detection timing near the center of the detection pulse of the calibration symbol 7C', and the detection of the alignment symbol 7C' is detected. The pulse is located near the center of the effective period T0 of the new gate signal Vgate_D1, and the timing of the effective period T0 of the new gate signal Vgate_D1 is adjusted.

另外，校排記號7A’~7D’，係如示於圖5，可替換成相對於捲筒紙4的搬送方向X而反轉印刷的校排記號7A”~7D”。在此情況下，係縱套版控制用邊緣7a係於檢測脈衝顯示為後邊緣，橫套版控制用邊緣7b於檢測脈衝顯示為前邊緣，惟可與上述同樣地進行套版控制，可與上述同樣地針對閘控信號的有效期間進行偏移調整。 Further, the alignment symbols 7A' to 7D' are replaced with the alignment symbols 7A" to 7D" which are reversely printed with respect to the conveyance direction X of the roll paper 4 as shown in Fig. 5 . In this case, the vertical plate control edge 7a is displayed as a trailing edge of the detection pulse, and the horizontal plate control edge 7b is displayed as a front edge at the detection pulse, but the plate control can be performed in the same manner as described above. Similarly, the offset adjustment is performed for the effective period of the gate signal.

此外，在以上係主要說明有關掃描頭8D的閘 控信號Vgate_D的有效期間的時機調整，惟掃描頭8B、8C的閘控信號Vgate_B、Vgate_C亦如同掃描頭8D的閘控信號Vgate_D，利用編碼器11B、11C而設定，故閘控信號Vgate_B、Vgate_C的有效期間亦與閘控信號Vgate_D同樣地調整時機。 In addition, in the above system, the gate related to the scanning head 8D is mainly explained. Timing adjustment of the effective period of the control signal Vgate_D, but the gate signals Vgate_B and Vgate_C of the scanning heads 8B, 8C are also set as the gate signal Vgate_D of the scanning head 8D, and are set by the encoders 11B, 11C, so the gate signals Vgate_B, Vgate_C The effective period is also adjusted in the same manner as the gate control signal Vgate_D.
