Description

  According to the present invention, each section of the belt-shaped body made of the base material that is easily stretched and processed in the pretreatment process is used as a printed material, and a printing cylinder and a printing cylinder are provided on each printed material conveyed by the belt-shaped material. The present invention relates to an electronic circuit printing method and apparatus for printing an electronic circuit at a contact point with a counter cylinder.

  In printing to print an electronic circuit on a substrate such as a film, the printed matter on which the first circuit is printed may be dried, the insulating film may be applied and dried thereon, and the second circuit may be printed thereon. . In this case, the second circuit needs to be printed with accurate alignment with the printed first circuit.

  For this purpose, usually, a reference mark (register mark) is printed together with the circuit when the circuit is printed for the first time, the position of the reference mark is detected, and the second circuit is adjusted in accordance with the detected position of the reference mark. Try to print.

  The background art described above is not publicly known. Further, the applicant has not been able to find prior art documents related to the present invention by the time of filing. Therefore, prior art document information is not disclosed.

  However, in the printing that prints the electronic circuit on the base material, the base material is an easily stretchable member such as a film, and the base material is greatly stretched and dried by heat once. Because the degree is different, just by aligning the position of the printing cylinder with the position of the detected fiducial mark as in conventional general printing, the circuit printed the second time can be accurately changed to the circuit printed the first time. There was a problem of not overlapping.

  Moreover, in the printing which prints the electronic circuit mentioned above on a base material, each area divided | segmented for every sheet | seat of a strip | belt-shaped body is made into a to-be-printed material (1st circuit), and this strip | belt-shaped body is the conveyance direction (top-bottom direction). Although the belt is transported in a stretched state, the belt is meandering during transportation because the belt is not firmly fixed with a nail or the like, and the circuit printed the second time is printed at the first time. There was a problem that the circuit did not overlap exactly.

  The present invention has been made to solve such a problem, and the object of the present invention is to print the first time regardless of the degree of expansion / contraction of the base material or the meandering of the belt-like body during transportation. An object of the present invention is to provide an electronic circuit printing method and apparatus capable of accurately aligning a circuit and a circuit printed a second time.

In order to achieve such an object, the present invention uses each section of the belt-shaped body made of the base material that is easily stretched and processed in the pretreatment process as a printing material, and the belt-shaped body is conveyed. In an electronic circuit printing method in which an electronic circuit is printed on each printed substrate at a contact point between a printing cylinder and a counter cylinder, a first reference mark is added to the substrate simultaneously with the printing of the electronic circuit on the substrate. A first reference mark adding step, and a region including the first reference mark of the printed material by the first imaging means provided in the middle of the transport path of the printed material that has passed between the printing cylinder and the counter cylinder. A first reference mark area imaging step for imaging, a first reference mark position detection step for detecting the position of the first reference mark from the image of the substrate imaged in the first reference mark area imaging step, and conveyance of the substrate Left direction orthogonal to direction The first left-right direction deviation amount calculating step for obtaining the right and left direction deviation amount from the reference position of the first reference mark from the position of the first reference mark detected in the first reference mark position detection step And the horizontal displacement of the first reference mark obtained in the first lateral displacement calculation step is divided by the time during which the substrate between the first reference marks passes through the contact point, A horizontal position adjustment step of obtaining a moving speed in the left-right direction and continuously adjusting the position of the printing cylinder in the left-right direction at the calculated moving speed during printing of the substrate between the first reference marks. It is characterized by providing.

  In the present invention, for example, when a belt-shaped body made of a base material that easily stretches is used as a film, and the first circuit is printed in each section divided for each sheet of the film, The circuit is printed a second time on the contact point between the printing cylinder and the counter cylinder on the first circuit (printed material) printed in the section. In the present invention, the first reference mark is added to the substrate simultaneously with the second circuit printing.

In the present invention, the printed material to which the first reference mark is added, that is, the printed material on which the electronic circuit (second circuit) is printed through the counter contact between the printing cylinder and the counter cylinder is the printed material. An area including the first reference mark of the printed material is imaged by the first imaging means provided in the middle of the transport path. Then, the position of the first reference mark is detected from the image of the substrate imaged by the first imaging means, and the reference position of the first reference mark is determined from the detected position of the first reference mark. The amount of deviation in the left-right direction (direction perpendicular to the conveyance direction (top and bottom direction) of the substrate) is obtained, and the amount of deviation of the first reference mark thus obtained is determined by the substrate between the first reference marks. The movement speed in the left-right direction of the printing cylinder is obtained by dividing by the time passing through the contact point, and the position in the left-right direction of the printing cylinder at the obtained movement speed is during printing of the substrate between the first reference marks. to be adjusted continuously.

Accordingly, in the present invention, the amount of deviation of each reference mark (first reference mark) in the left-right direction from the reference position is obtained by dividing the amount of time that the printed material between the first reference marks passes through the contact point. The horizontal position of the printing cylinder is continuously adjusted during printing of the printed material between the reference marks at the moving speed, so that the horizontal position shift of each reference mark caused by stretching or meandering can be reduced. And correct the printing of the electronic circuit (second circuit) on each substrate (first circuit) regardless of the degree of expansion / contraction of the base material or the meandering of the belt-like material being conveyed. It is possible to make it happen.

  In the present invention, in the pretreatment step, a second reference mark is further added to each of the printed materials, and the second imaging means is provided in the middle of the conveying path of the printed material to the contact point between the printing cylinder and the counter cylinder. And detecting the position of the second reference mark from the image of the printed material imaged by the second imaging means, and imaging the region including the second reference mark of the printed material. The amount of deviation in the left-right direction from the previously detected second reference mark is obtained from the position of the second reference mark thus determined, and the amount of deviation in the left-right direction of the first reference mark and the second reference mark The position of the printing cylinder in the left-right direction may be continuously adjusted during printing of the printing material between the first reference marks according to the amount of left-right displacement between them.

  As a result, the amount of lateral displacement of the section where the printed material is printed is obtained from the amount of lateral displacement of the first reference mark, and the material to be printed is printed based on the amount of lateral displacement between the second reference marks. The amount of deviation in the left-right direction up to the previous is obtained, and in printing, the position of the printing cylinder in the left-right direction is continuously adjusted in consideration of the obtained two amounts of deviation in the left-right direction. Regardless of the degree of expansion / contraction, printing of the electronic circuit (second circuit) on each substrate (first circuit) can be performed in an overlapping manner.

According to the present invention, the first fiducial mark is added to each of the printed materials simultaneously with the printing of the electronic circuit, and the first reference mark is placed in the middle of the conveying path of the printed material that has passed between the printing cylinder and the counter cylinder. An image pickup unit is provided, and the first image pickup unit picks up an image of a region including the first reference mark of the printed material, and the first reference mark is obtained from the image of the printed material picked up by the first image pickup device. The position is detected, and from the detected position of the first reference mark, the amount of deviation in the left-right direction (direction orthogonal to the conveyance direction of the substrate) from the reference position of the first reference mark is obtained. The obtained shift amount of the first reference mark is divided by the time during which the printed material between the first reference marks passes through the contact point to determine the moving speed of the printing cylinder in the left-right direction. The left and right position of the printing cylinder is the first reference mark During the printing of the substrate , the adjustment was made continuously, so that the misalignment in the left and right direction of each fiducial mark caused by stretching or meandering was corrected, and the degree of expansion / contraction of the substrate or during transportation Regardless of the meandering of the belt-like body, printing of the electronic circuit (second circuit) on each substrate (first circuit) can be performed so as to overlap accurately.

[Operation of drive controller]
Next, the operation of the drive control apparatus 200 in the electronic circuit printing apparatus will be described with the operation of the deviation amount detection apparatus 300.

  In the following operations, the CPU 201 of the drive control device 200 and the CPU 301 of the deviation amount detection device 300 write various data obtained by calculation into the memory M or read various data from the memory M as necessary. However, here, in order to avoid complicated explanation, and because it is obvious from the name of the memory M and the symbols added to the memory M, the explanation of the read / write operation to the memory M is omitted. In some cases.

  The CPU 201 of the drive control apparatus 200 reads the printing speed Vs from the memory M1 (FIG. 15: Step S101), calculates the rotation speed VIr of the reference impression cylinder driving motor from the read printing speed Vs (Step S102). The calculated reference rotational speed VIr of the impression cylinder drive motor is written in the memory M2 (step S102), and is output to the impression cylinder drive motor driver 208 via the D / A converter 211 (step S103). As a result, the impression cylinder 3 rotates at the reference rotation speed VIr.

  The CPU 201 calculates the reference plate cylinder / rubber cylinder driving motor rotation speed VPr from the printing speed Vs, and writes the calculated reference cylinder / rubber cylinder driving motor rotation speed VPr to the memory M3. (Step S104), and output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (Step S105). As a result, the plate cylinder 1 and the rubber cylinder 2 rotate at the reference rotation speed VPr.

  Further, as an initial setting, the CPU 201 writes “2” as a value indicating that the phase deviation correction by the first register mark is not completed in the memory M4 (step S106), and the phase deviation by the second register mark in the memory M5. “2” is written as a value indicating that the correction is not completed (step S107).

Further, the CPU 201 writes “1” as the expansion / contraction rate η2 between FF and FB in the memory M6 (step S108). Also, zero is written in the memory M7 as the average value Δx3 _av of the amount of deviation of the third register mark in the X direction (step S109). That is, as an initial setting, the expansion rate η2 between FF and FB is set to η2 = 1, and the average value Δx3 _av of the third register mark in the X direction is set to Δx3 _av = 0.

[Image capture command of WG camera to deviation detection device from drive control device]
Then, the CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 16: step S110), and the current rotation phase ψ of the impression cylinder 3 from the read count value of the impression cylinder rotation phase detection counter 210. _R is calculated (step S111). Then, the reference imaging position PWGr of the WG camera is read from the memory M10 (step S112), and it is confirmed whether or not the current rotational phase ψ _R of the impression cylinder 3 is at the reference imaging position PWGr of the WG camera (step S113).

When the CPU 201 repeats the processing operations of steps S110 to S113 and confirms that the current rotation phase ψ _R of the impression cylinder 3 has reached the reference imaging position PWGr of the WG camera (YES in step S113), the number of rotations of the printing press An enable signal and a reset signal are output to the counter 213 for counting (step S114), and output of the reset signal to the counter 213 for counting the number of rotations of the printing press is stopped (step S115). As a result, the counter 213 for counting the number of rotations of the printing press starts counting from zero.

  The CPU 201 transmits an imaging command of the WG camera to the deviation amount detection apparatus 300 simultaneously with the start of counting from zero of the counter 213 for counting the number of rotations of the printing press (step S116), and sends a response from the deviation amount detection apparatus 300. Wait (steps S117 and S119 (FIG. 17)).

  If a signal without the first register mark is transmitted from the deviation amount detection device 300 (YES in step S117), the CPU 201 transmits a signal reception completion signal without the first register mark to the deviation amount detection device 300. (Step S118), the process returns to step S110.

  If the displacement amount detection device 300 transmits the displacement amount Δx1 in the X direction and the displacement amount Δy1 in the Y direction of the first register mark (YES in step S119), the CPU 201 has transmitted from the displacement amount detection device 300. The shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark are written in the memories M11 and M12 (step S120).

[Image of printed material by WG camera (detection of shift amount of first register mark by shift amount detection device)]
When the image pickup command for the WG camera is sent from the drive control device 200 (FIG. 51: YES in step S401), the CPU 301 of the deviation amount detection device 300 outputs the image pickup command to the WG camera 304 (step S402). Thereby, at the timing when the imaging command of the WG camera is sent from the drive control device 200, that is, at the timing when the current rotational phase ψ _R of the impression cylinder 3 is located at the reference imaging position PWGr of the WG camera. An image of a substrate to be printed on the web 4 on which 304 is conveyed is captured.

  When image data is sent from the WG camera 304 (YES in step S403), the CPU 301 sets the count value Y in the memory M71 to 1 (step S404), and sets the count value X in the memory M72 to 1 (step S405). ), The imaging data at the pixel position specified by the count values X and Y from the WG camera 304 is written in the (X, Y) address position of the memory M73 (step S406).

  Then, the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 52: step S407), reads the number of pixels a in the left-right direction of the WG camera in the memory M74 (step S408), and counts in step S409. The processing operations in steps S406 to S409 are repeated until X exceeds the number of pixels a in the left-right direction of the WG camera.

  If the count value X exceeds the number of pixels a in the left-right direction of the WG camera (YES in step S409), 1 is added to the count value Y in the memory M71 (step S410), and the top and bottom of the WG camera in the memory M75. The number of pixels b in the direction is read (step S411), and the processing operations in steps S405 to S412 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the WG camera in step S412.

  Thereby, the imaging data of the a × b pixel from the WG camera 304 is stored in the memory M73. Here, as shown in FIG. 74 (a), imaging data of a wide area including the first register mark RM1 of the first substrate # 1 is stored in the memory M73 as imaging data of a × b pixels. And

  In the memory M78, as shown in FIG. 74B, the c × d pixel data of the first register mark RM1 is stored as pattern matching data. Further, the vertical direction of the WG camera 304 is a flow direction of the web 4, and the left-right direction of the WG camera 304 is a direction orthogonal to the flow direction of the web 4.

  Next, the CPU 301 sets the count value Y in the memory M71 to 1 (step S413), sets the count value X in the memory M72 to 1 (step S414), and sets the count value N in the memory M76 to 1 (FIG. 53: FIG. 53). In step S415, the count value M in the memory M77 is set to 1 (step S416).

  Then, the imaging pixel data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M73 is read (step S417), and the first register mark at the address position (M, N) in the memory M78 is read. The pixel data is read (step S418). The read pixel data of the WG camera at the address position (X + M-1, Y + N-1) in the memory M73 and the (M, N) address position in the memory M78. It is confirmed whether or not the pixel data of one register mark matches (see step S419, FIGS. 74A and 74B).

  Here, the image data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M73 and the pixel data of the first register mark at the address position (M, N) in the memory M78 are identical. If not (NO in step S419), any pixel data of the imaging data of the WG camera 304 from the address (X, Y) to the address (X + c-1, Y + d-1) at that time is stored in the first register. Unlike the mark pixel data, there is no first register mark in the range starting from the address (X, Y), so the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 54: step S420). ) Read the horizontal pixel number a of the WG camera in the memory M74 and the horizontal pixel number c of the first register mark in the memory M79 (step). S421, S422), in step S423 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S415～S423.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S423), the left and right ends of the image data of the WG camera 304 have been exceeded, so the CPU 301 stores the memory M71 in the memory M71. 1 is added to the count value Y (step S424), and the vertical pixel count b of the WG camera in the memory M75 and the vertical pixel count d of the first register mark in the memory M80 are read (steps S425 and S426). ), The processing operation of steps S414 to S427 is repeated until the count value Y exceeds “b−d + 1” in step S427.

  During this processing operation, the imaging pixel data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M73 and the pixel data of the first register mark at the address position (M, N) in the memory M78 Are confirmed (FIG. 53: YES in step S419), the CPU 301 adds 1 to the count value M in the memory M77 (step S430), and the left and right of the first register mark are read from the memory M79. The number of pixels c in the direction is read (step S431), and the processing operations in steps S417 to S432 are repeated until the count value M exceeds the number c of pixels in the left and right direction of the first register mark in step S432 (FIG. 55).

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S432), the CPU 301 adds 1 to the count value N in the memory M76 (step S433), and the first value from the memory M80. The number of pixels d in the vertical direction of the register mark is read (step S434), and the processing operations of steps S416 to S435 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first register mark in step S435.

  In this manner, the CPU 301 performs pattern matching of the pixel data of the c × d first register mark in the memory M78 with respect to the imaging data of the a × b pixel in the memory M73, and the count value N is the first value. When the number of pixels d in the vertical direction of the register mark is exceeded (YES in step S435), the address (X + c-1, Y + d-1) from the (X, Y) address of the imaging data of the a × b pixel in the memory M73. It is determined that the pixel data of the c × d first register mark in the memory M78 is included in the range up to That is, it is determined that the first register mark RM1 is included in the image captured by the WG camera 304.

  If the count value Y exceeds “b−d + 1” in step S427 (FIG. 54) (YES in step S427), it means that the edge of the image data of the WG camera 304 has been exceeded and the CPU 301 Determines that the first register mark RM1 is not included in the image captured by the WG camera 304, and transmits a signal without the first register mark to the drive control device 200 (step S428). Then, upon receiving a signal reception completion signal without the first register mark from the drive control device 200 (YES in step S429), the process returns to step S401 (FIG. 51), and the imaging command for the next WG camera from the drive control device 200 is received. Prepare for.

  When CPU 301 determines that the first register mark is included in the image captured by WG camera 304 (FIG. 55: YES in step S435), CPU 301 reads count value X in memory M72 at that time (step S436). The measurement position in the X direction of the first register mark is calculated from the read count value X, and written to the address position in the X direction in the memory M81 (step S437). Then, the reference position in the X direction of the first register mark is read from the address position in the X direction of the memory M82 (step S438), and the reference position in the X direction of the first register mark is determined from the measurement position in the X direction of the first register mark. Subtraction is performed to obtain an X-direction deviation amount Δx1 of the first register mark (see FIG. 74C), and the obtained X-direction deviation amount Δx1 of the first register mark is written in the X-direction address position of the memory M83. (Step S439).

  Further, the CPU 301 reads the count value Y in the memory M71 at that time (FIG. 56: step S440), calculates the measurement position in the Y direction of the first register mark from the read count value Y, and Y in the memory M81. Write to the address position in the direction (step S441). Then, the reference position in the Y direction of the first register mark is read from the address position in the Y direction of the memory M82 (step S442), and the reference position in the Y direction of the first register mark is determined from the measurement position in the Y direction of the first register mark. Subtraction is performed to determine the amount of displacement Δy1 in the Y direction of the first register mark (see FIG. 74 (c)), and the amount of displacement Δy1 in the Y direction of the first register mark thus determined is written to the address position in the Y direction of the memory M83. (Step S443).

  The CPU 301 transmits to the drive control device 200 the X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 of the first register mark written in the memory M83 (step S444). Then, upon receipt of the first register mark shift amount reception completion signal from the drive control device 200 (YES in step S445), the first register mark shift amount Δx1 in the X direction and the shift in the Y direction to the drive control device 200. The transmission of the amount Δy1 is stopped (step S446), and the process returns to step S401 (FIG. 51) to prepare for the next WG camera imaging command from the drive control device 200.

[Detection of the position of the first register mark in the drive control unit]
When the CPU 201 of the drive control device 200 receives the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark transmitted from the shift amount detection device 300 (FIG. 17: YES in step S119), The received shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark are written in the memories M11 and M12 (step S120), and a shift amount reception completion signal for the shift amount of the first register mark is transmitted to the shift amount detection device 300. (Step S121).

The CPU 201 sets the count value N of the memory M13 to N = 2 (step S122), reads the reference imaging position PWGr of the WG camera from the memory M10 (step S123), and shifts the first register mark in the Y direction from the memory M12. The amount Δy1 is read (step S124), and the current original imaging position of the WG camera (imaging position of the WG camera) PWG ₁ is obtained from the reference imaging position PWGr of the WG camera and the shift amount Δy1 of the first register mark in the Y direction. The obtained imaging position PWG ₁ of the WG camera is written in the memory M14 (step S125).

Note that the current original imaging position PWG ₁ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. And the imaging timing of the third register mark in the FB camera.

Further, CPU 201 from the memory M15 read the WG camera -FF camera distance L1 (step S126), the first FF camera than WG camera imaging position PWG ₁ and WG camera -FF inter-camera distance L1 calculated in step S125 obtains an imaging position PFF _1, it writes the image pickup position PFF ₁ of the first FF cameras found in the first address position of the memory M16 (step S127).

Further, CPU 201 from the memory M17 read the WG camera -FB camera distance L3 (step S128), the first FB camera than WG camera imaging position PWG ₁ and WG camera -FB inter-camera distance L3 obtained in step S125 obtains an imaging position PFB _1, writes the image pickup position PFB ₁ of the first FB camera determined in the first address position of the memory M18 (Fig. 18: step S129).

FIG. 71 shows the WG camera's reference imaging position PWGr, the WG camera's reference imaging position PWGr, and the first register mark's Y-direction shift amount Δy1 (the WG camera's current original imaging). Position) PWG ₁ , WG camera imaging position PWG ₁ and WG camera-FF camera distance L ₁ , WG camera imaging position PFF ₁ , WG camera imaging position PWG _1, and WG camera-FB camera distance The imaging position PFB ₁ of the FB camera obtained from L3 is shown.

In FIG. 71, PFFr is a reference image pickup position of the first FF camera, PIr is a reference print point arrival position of the first substrate, PFBr is a reference image pickup position of the first FB camera, and a reference image pickup position of the WG camera. The PWGr and the reference imaging position PFFr of the FF camera are separated by 4 or more (in this example, approximately 4.3 sheets) as the number of printed materials, and the reference imaging position PFFr of the FF camera and the reference printing point of the printed material. The arrival position PIr is one or more sheets (in this example, approximately 1.16 sheets) as the number of printed materials. Further, the reference imaging position PWGr of the WG camera and the reference imaging position PFBr of the FB camera are separated by 6 or more (in this example, approximately 6.15) as the number of printed materials. PI ₁ is the printing point arrival position of the first substrate # 1, and the printing point arrival position PI ₁ of the first substrate # ₁ will be described later.

After writing the imaging position PFB ₁ of the FB camera in the memory M18 (FIG. 18: step S129), the CPU 201 reads the reference distance M1Lr between the first register marks from the memory M19 (step S130), and the WG obtained in step S125. The next WG camera imaging position PWG _2next is obtained from the camera imaging position PWG ₁ and the reference distance M1Lr between the first register marks, and is overwritten in the memory M14 (step S131).

Then, the count value is read from the counter 213 for counting the number of rotations of the printing press (step S132), and the count value is read from the counter 210 for detecting the pressure drum rotation phase (step S133). The current unwinding length l of the web 4 is obtained from the count value and the count value of the impression cylinder rotation phase detection counter 210 (step S134). Then, the imaging position PWG _2next of the next WG camera is read from the memory M14 (step S135), and it is confirmed whether or not the unwinding length l of the current web 4 has reached the imaging position PWG _2next of the next WG camera. (Step S136).

[Adjustment of initial rough rotation phase of plate cylinder / rubber cylinder (first registration)]
The CPU 201 performs the processing operations of steps S137 (FIG. 19) to S156 (FIG. 21) until it is confirmed in step S136 that the next WG camera has reached the imaging position _PWG2next of the web 4 unwinding length l. repeat. In the processing of steps S137 to S156, the initial rough rotation phase of the plate cylinder / rubber cylinder is adjusted. The initial rough rotation phase of the plate cylinder / rubber cylinder is adjusted as follows.

The CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 19: step S137), and obtains the current rotation phase ψ _R of the impression cylinder from the read count value of the impression cylinder rotation phase detection counter 210. (Step S138). Then, the amount of displacement Δy1 in the Y direction of the first register mark is read from the memory M12 (step S139), and the amount of displacement Δy1 in the Y direction of the first register mark is added to the current rotational phase ψ _R of the impression cylinder to correct it. The current rotation phase ψ _R ′ of the impression cylinder is obtained (step S140).

Then, the CPU 201 obtains the rotation phase φm of the plate cylinder / rubber cylinder that should be based on the corrected current rotation phase ψ _R ′ of the impression cylinder (step S141), and the count value from the plate cylinder / rubber cylinder rotation phase detection counter 217. (Step S142), and the current rotational phase φ _R of the plate cylinder / rubber cylinder is obtained from the read count value of the plate cylinder / rubber cylinder rotation phase detection counter 217 (step S143). Then, the current rotation phase φ _R of the plate cylinder / rubber cylinder is subtracted from the rotation phase φm of the plate cylinder / rubber cylinder obtained in step S141 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. Then, the current rotational phase difference Δφ _R of the obtained plate cylinder / rubber cylinder is written in the memory M26 (step S144).

Then, CPU 201 obtains the current absolute value of the rotational phase difference [Delta] [phi _R of the current plate cylinder, blanket cylinder from the rotational phase difference [Delta] [phi _R of the plate cylinder, blanket cylinder obtained in step S144 (FIG. 20: Step S145) Then, the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder is read from the memory M28 (step S146), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is obtained from the plate cylinder and the rubber cylinder. It is confirmed whether or not the rotation phase difference is equal to or smaller than a first allowable value α1 (step S147).

If the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is not less than the first allowable value α1 of the rotational phase difference of the plate cylinder / rubber cylinder (NO in step S147), the CPU 201 The correction value conversion table of the current rotational phase difference / rotational speed of the plate cylinder / rubber cylinder is read from the memory M29 (step S148), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M26 (step S148). S149) Using the current rotational phase difference-rotational speed correction value conversion table of the plate cylinder / rubber cylinder, a rotational speed correction value ΔV is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder (step S150). ).

  Then, the CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S151), and the rotation speed correction value ΔV of the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor is read. Is added to obtain a corrected rotation speed VPr ′ of the plate cylinder / rubber cylinder driving motor (step S152), and the corrected rotation speed VPr ′ of the plate cylinder / rubber cylinder driving motor is determined as the plate cylinder / rubber cylinder. The signal is output to the drive motor driver 215 via the D / A converter 218 (step S153), and the process returns to step S132 (FIG. 18) to repeat the same operation.

As a result, the rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted, and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is the first allowable value of the rotational phase difference of the plate cylinder / rubber cylinder. The value α1 or less is adjusted.

When the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder becomes equal to or less than the first allowable value α1 of the rotational phase difference of the plate cylinder / rubber cylinder (FIG. 20: YES in step S147), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 21: Step S154), and the read standard rotation speed VPr of the plate cylinder / rubber cylinder driving motor is read as the printing cylinder / rubber. The data is output to the drum driver motor driver 215 via the D / A converter 218 (step S155), and “1” is written in the memory M4 as a value indicating that the correction of the phase deviation by the first register mark is completed (step S155). S156).

The CPU 201 repeats the processing operations in steps S137 to S156 until the unwinding length l of the web 4 reaches the imaging position PWG _2next of the next WG camera. In step S147, the current rotational position of the plate cylinder / rubber cylinder is repeated. If the absolute value of the phase difference Δφ _R is not less than or equal to the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder, the process does not proceed to steps S154 to S156. In this case, “2” is still written in the memory M4 as a value indicating that the correction of the phase deviation by the first register mark is not completed.

When the unwinding length l of the web 4 reaches the imaging position PWG _2next of the next WG camera (FIG. 18: YES in step S136), the CPU 201 transmits an imaging command for the WG camera to the deviation amount detection device 300 (FIG. 18). 22: Step S157), and waits for a response from the deviation amount detection device 300 (Step S158). The CPU 301 of the deviation amount detection device 300 receives an imaging command of the WG camera from the drive control device 200, images the printed material on the web 4 being conveyed by the WG camera 304, and performs the first register in the same manner as described above. The amount of mark deviation is detected.

  When the CPU 201 of the drive control device 200 receives the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark from the shift amount detection device 300 (YES in step S158), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M11 and M12 (step S159), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S160).

Then, the CPU 201 reads the WG camera imaging position PWG _2next from the memory M14 (step S161), and reads the first register mark displacement amount Δy1 in the Y direction from the memory M12 (step S162), and WG camera imaging position PWG _2next. The current original image pickup position (image pickup position of the WG camera) PWG ₂ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained image pickup position PWG ₂ of the WG camera is overwritten in the memory M14. (Step S163).

Further, the CPU 201 reads the WG camera-FF camera distance L1 from the memory M15 (step S164), reads the count value N (N = 2) from the memory M13 (step S165), and captures the WG camera image obtained in step S163. the position PWG ₂ and WG camera -FF camera distance L1 seeking imaging position PFF ₂ of the next FF camera, the determined address location of the N-th image pickup position PFF ₂ of the next FF camera memory M16 (2-th) (See step S166, FIG. 77 (a)).

The CPU 201 reads the WG camera-FB camera distance L3 from the memory M17 (FIG. 23: step S167), reads the count value N (N = 2) from the memory M13 (step S168), and obtains the WG obtained in step S163. obtains an imaging position PFB ₂ of the next FB camera from the imaging position PWG ₂ and WG camera -FB inter-camera distance L3 of the camera, N-th memory M18 the determined imaging position PFB ₂ of the next FB camera (second) (Refer to step S169, FIG. 78 (a)).

Then, read the reference distance M1Lr between the first register mark from the memory M19 (step S170), the reference distance next WG camera imaging than M1Lr between imaging positions PWG ₂ and first register marks of WG camera obtained in step S163 The position PWG _3next is obtained and overwritten in the memory M14 (step S171), and 1 is added to the count value N of the memory M13 to set N = 3 (step S172).

  Then, the CPU 201 confirms whether or not the count value N is N = 6 (step S173), and repeats the processing operations of steps S132 (FIG. 18) to S173 until N = 6 in step S173.

Thus, in the same manner as described above, the imaging positions PWG _4next , PWG _5next , PWG _{6next of} the next WG camera, the imaging positions PFF ₃ , PFF ₄ , PFF _{5 of} the next FF camera, and the imaging position PFB ₃ of the next FB camera , PFB ₄ , and PFB ₅ are obtained, and as shown in FIG. 77 (b), the imaging position PFF ₃ of the FF camera is at the third address position of the memory M16, and the imaging position PFF of the FF camera is at the fourth address position. ₄ , the imaging position PFF5 of the FF camera is written in the _fifth address position. Also, as shown in FIG. 78 (b), the imaging position PFB ₃ of the FB camera is at the third address position of the memory M18, and the imaging position PFB ₄ of the FB camera is at the fifth address position at the fourth address position. The imaging position PFB ₅ of the FB camera is written into the area.

  When the CPU 201 confirms that the count value N is N = 6 (YES in step S173), the CPU 201 reads the value written in the memory M4 (step S174), and the value written in the memory M4 is changed. It is confirmed whether or not “1” (step S175). If the value written in the memory M4 is not “1” (NO in step S175), the process returns to step S106 (FIG. 15), but if the value written in the memory M4 is “1”. (YES in step S175), it is determined that the phase deviation correction by the first register mark has been completed.

  In this way, in the present embodiment, the count value is detected after the position of the first register mark RM1 is detected from the first image of the substrate # 1 imaged by the WG camera 304 (point t1 shown in FIG. 71). Until N reaches N = 6 (point t2 shown in FIG. 71), the initial coarse rotation phase of the plate cylinder / rubber cylinder is adjusted according to the position of the first register mark RM1 (first registration). Will be done.

Normally, before the count value N reaches N = 3, that is, before the unwinding length l of the web 4 reaches the imaging position PWG _2next of the WG camera, the first registration (plate cylinder / rubber cylinder) The initial coarse rotation phase adjustment) is completed. If the first registration is not completed before reaching the imaging position PWG _2next of the WG camera, the first registration is continued until the count value N reaches N = 6.

In this embodiment, the first registration is continued until the count value N reaches N = 6. However, as shown in FIG. 72 as an interval from the point t1 to the point t2, Until the unwinding length l of the web 4 reaches the imaging position PFF ₁ of the FF camera, that is, until the area including the second register mark RM2 of the first substrate # 1 is imaged by the FF camera 305. In the meantime, the first registration may be completed.

[Image capture command of FF camera to deviation detection device from drive control device]
When the CPU 201 determines that the correction of the phase deviation by the first register mark has been completed (FIG. 23: YES in step S175), the CPU 201 sets the count value M in the memory M32 to 1 (step S176) and the memory M33. The count value L is set to 1 (step S177), the count value is read from the counter 213 for counting the number of rotations of the printing press (FIG. 24: step S178), and the count value is read from the counter 210 for detecting the rotation of the impression cylinder rotation ( In step S179), the present web 4 unwinding length 1 is obtained from the count value of the counter 213 for counting the number of rotations of the printing press and the count value of the impression cylinder rotation phase detection counter 210 (step S180). Then, the imaging position PWG _6next of the next WG camera is read from the memory M14 (step S181), and it is confirmed whether or not the unwinding length l of the current web 4 has reached the imaging position PWG _6next of the next WG camera. (Step S182).

In this case, since the unwinding length l of the current web 4 has not yet reached the imaging position PWG _6next of the next WG camera (NO in step S182), the CPU 201 starts FF from the first address position in the memory M16. The camera imaging position PFF ₁ is read (FIG. 25: Step S183), and it is confirmed whether or not the current unwinding length 1 of the web 4 has reached the imaging position PFF ₁ of the FF camera (Step S184).

Here, if the unwinding length l of the current web 4 has not reached the imaging position PFF ₁ of the FF camera (NO in step S184), the CPU 201 reads the count value M in the memory M32 (FIG. 27: step). S185), it is confirmed whether or not the count value M is “2” (step S186). In this case, since the count value M is “1” (NO in step S186), the process returns to step S178 (FIG. 24), and the processing operations in steps S178 to S186 are repeated.

When the CPU 201 confirms that the unwinding length l of the current web 4 has reached the imaging position PFF ₁ of the FF camera during this processing operation (FIG. 25: YES in step S184), the CPU 201 sends an FF to the deviation amount detection device 300. An imaging command for the camera is transmitted (step S187), and transmission of a displacement amount Δx2 in the X direction and a displacement amount Δy2 in the Y direction of the second register mark from the displacement amount detection device 300 is awaited (step S188).

[Image capture of printed material by FF camera (detection of deviation of second register mark by deviation detection device)]
When an imaging command for the FF camera is sent from the drive control device 200 (FIG. 57: YES in step S448), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the FF camera 305 (step S449). Thereby, the FF camera 305 is conveyed at the timing when the imaging command of the FF camera is sent from the drive control device 200, that is, at the timing when the unwinding length l of the web 4 reaches the imaging position PFF ₁ of the FF camera. An image of the printing material on the incoming web 4 is taken.

  When image data is sent from the FF camera 305 (YES in step S450), the CPU 301 sets the count value Y in the memory M71 to 1 (step S451) and sets the count value X in the memory M72 to 1 (step S452). ), The imaging data of the pixel position specified by the count values X and Y from the FF camera 305 is written in the address position (X, Y) of the memory M84 (step S453).

  Then, the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 58: Step S454), reads the number of pixels e in the left-right direction of the FF camera in the memory M85 (Step S455), and counts in Step S456. The processing operations in steps S453 to S456 are repeated until X exceeds the number of pixels e in the left-right direction of the FF camera.

  If the count value X exceeds the pixel number e in the left-right direction of the FF camera (YES in step S456), 1 is added to the count value Y in the memory M71 (step S457), and the top and bottom of the FF camera in the memory M86. The number of pixels f in the direction is read (step S458), and the processing operations in steps S452 to S459 are repeated until the count value Y exceeds the number of pixels f in the vertical direction of the FF camera in step S459.

  As a result, the imaging data of the e × f pixels from the FF camera 305 is stored in the memory M84. Here, as shown in FIG. 75 (a), it is assumed that imaging data of an area including the second register mark RM2 of the substrate # 1 is stored in the memory M84 as imaging data of e × f pixels.

  The memory M87 stores g × h pixel data of the second register mark as pattern matching data, as shown in FIG. 75 (b). The vertical direction of the FF camera 305 is the flow direction of the web 4, and the left-right direction of the FF camera 305 is a direction orthogonal to the flow direction of the web 4.

  When the count value Y exceeds the number of pixels f in the vertical direction of the FF camera (YES in step S459), the CPU 301 sets the count value Y in the memory M71 to 1 (FIG. 59: step S460), and the count value in the memory M72. X is set to 1 (step S461), the count value N in the memory M76 is set to 1 (step S462), and the count value M in the memory M77 is set to 1 (step S463).

  Then, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M84 is read (step S464), and the second register mark at the address position (M, N) in the memory M87 is read. The pixel data is read (step S465), and the read image data of the FF camera at the address position (X + M-1, Y + N-1) in the memory M84 and the (M, N) address position in the memory M87 are read. It is confirmed whether or not the pixel data of the two register marks match (see step S466, FIGS. 75A and 75B).

  Here, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M84 and the pixel data of the second register mark at the address position (M, N) in the memory M87 are identical. If not (NO in step S466), any pixel data of the imaging data of the FF camera 305 from the address (X, Y) to the address (X + g-1, Y + h-1) at that time is stored in the second register. Unlike the mark pixel data, there is no second register mark in the range starting from the address (X, Y), so the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 60: step S467). ) Read the horizontal pixel number e of the FF camera in the memory M85 and the horizontal pixel number g of the second register mark in the memory M88 (step). S468, S469), in step S470 until the count value X exceeds "e-g + 1", and repeats the processing operation in steps S462～S470.

  If the count value X exceeds “e−g + 1” during this processing operation (YES in step S470), it means that the left and right ends of the imaging data of the FF camera 305 have been exceeded, so the CPU 301 stores the data in the memory M71. 1 is added to the count value Y (step S471), and the vertical pixel count f of the FF camera in the memory M86 and the vertical pixel count h of the second register mark in the memory M89 are read (steps S472 and S473). ), The processing operations of steps S461 to S474 are repeated until the count value Y exceeds “f−h + 1” in step S474.

  During this processing operation, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M84 and the pixel data of the second register mark at the address position (M, N) in the memory M87. Are confirmed (FIG. 59: YES in step S466), the CPU 301 adds 1 to the count value M in the memory M77 (FIG. 61: step S476), and the second register from the memory M88. The number of pixels g in the left-right direction of the mark is read (step S477), and the processing operations in steps S464 to S478 are repeated until the count value M exceeds the number of pixels g in the left-right direction of the second register mark in step S478.

  When the count value M exceeds the left-right pixel count g of the second register mark (YES in step S478), 1 is added to the count value N in the memory M76 (step S479), and the second register mark is read from the memory M89. The number h of pixels in the vertical direction is read (step S480), and the processing operations in steps S463 to S481 are repeated until the count value N exceeds the number h of pixels in the vertical direction of the second register mark in step S481.

  In this way, the CPU 301 performs pattern matching of the pixel data of the g × h second register mark in the memory M87 with respect to the imaging data of the e × f pixel in the memory M84, and the count value N is the second value. When the number of pixels h in the vertical direction of the register mark is exceeded (YES in step S481), the address (X + g-1, Y + h-1) from the (X, Y) address of the imaging data of the e × f pixel in the memory M84. It is determined that the pixel data of the g × h second register mark in the memory M87 is included in the range up to. That is, it is determined that the second register mark RM2 is included in the image captured by the FF camera 305.

  If the count value Y exceeds “f−h + 1” in step S474 (FIG. 60) (YES in step S474), it means that the edge of the imaging data of the FF camera 305 has been exceeded, and the CPU 301 Determines that the second register mark is not included in the image captured by the FF camera 305, and displays an error message “No second register mark” on a display (not shown) (step S475).

  When the CPU 301 determines that the second register mark is included in the image captured by the FF camera 305 (YES in step S481), the CPU 301 reads the count value X in the memory M72 at that time (step S482) and reads the read value. The measurement position in the X direction of the second register mark is calculated from the count value X and written in the address position in the X direction in the memory M90 (FIG. 62: step S483). Then, the X-direction reference position of the second register mark is read from the X-direction address position of the memory M91 (step S484), and the X-direction reference position of the second register mark is determined from the X-direction measurement position of the second register mark. Subtraction is performed to obtain the amount of deviation Δx2 in the X direction of the second register mark (see FIG. 75C), and the obtained amount of deviation Δx2 in the X direction of the second register mark is written to the address position in the X direction of the memory M92. (Step S485).

  Further, the CPU 301 reads the count value Y in the memory M71 at that time (step S486), calculates the Y-direction measurement position of the second register mark from the read count value Y, and the Y-direction address in the memory M90. The position is written (step S487). Then, the reference position in the Y direction of the second register mark is read from the address position in the Y direction of the memory M91 (FIG. 63: step S488), and the Y register in the Y direction is measured from the measurement position in the Y direction of the second register mark. The reference position is subtracted to determine the amount of deviation Δy2 in the Y direction of the second register mark (see FIG. 75C), and the amount of deviation Δy2 in the Y direction of the second register mark thus obtained is used as the address in the Y direction of the memory M92. The position is written (step S489).

  Then, the CPU 301 transmits to the drive control device 200 the amount of displacement Δx2 in the X direction and the amount of displacement Δy2 in the Y direction of the second register mark written in the memory M92 (step S490). Then, upon receipt of the second register mark shift amount reception completion signal from the drive control device 200 (YES in step S491), the second register mark shift amount Δx2 in the X direction to the drive control device 200 and the shift in the Y direction. The transmission of the amount Δy2 is stopped (step S492), and the process returns to step S401 (FIG. 51) to prepare for the next WG camera imaging command from the drive control device 200.

[Detection of position of second register mark in drive control device (detection of position of previous second register mark)]
When the CPU 201 of the drive control device 200 receives the displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction of the second register mark transmitted from the displacement amount detection device 300 (FIG. 25: YES in step S188), The received X-direction displacement amount Δx2 and Y-direction displacement amount Δy2 of the received second register mark are written in the memories M34 and M35 (step S189), and the displacement amount detection device 300 transmits a displacement amount reception completion signal of the second register mark. (Step S190).

Then, the CPU 201 reads the imaging position PFF ₁ of the FF camera from the first address position of the memory M16 (FIG. 24: step S191), and the amount of deviation Δy2 in the Y direction between the imaging position PFF ₁ of the FF camera and the second register mark. from the second register obtains the Y-direction position PM2Y ₁ mark, the determined second register mark Y direction position PM2Y ₁ of the second register mark before the Y-direction position (the last detected from the captured image of the FF camera It is written in the memory M36 as a Y-direction position) PM2Y _F of the second register mark (step S192, FIG. 79 (a), see FIG. 86). Further, the deviation amount in the X direction of the second register mark from the memory M34 .DELTA.x2 reads (Δx2 _(1)), the read shift amount in the X direction of the second register mark Δx2 (Δx2 ₍₁₎₎ second previous written in the memory M37 as the X-direction position PM2X _F of the register mark (step S193, FIG. 80 (a), see FIG. 86).

The CPU 201 reads the Y-direction position PM2Y _F (PM2Y ₁ ) of the second register mark before the memory M36 (step S194), reads the FF camera-print point distance L2 from the memory M38 (step S195), The print point arrival position PI ₁ of the first substrate # 1 is obtained from the Y-direction position PM2Y _F (PM2Y ₁ ) of the second register mark and the FF camera-print point distance L2, and the obtained first substrate # 1 is obtained. writing the print point reaches the position PI ₁ of the first address position of the memory M39 (see step S196, FIG. 81 (a)).

Further, the CPU 201 arrives at the print point of the virtual substrate before the first substrate # 1 based on the Y-direction position PM2Y _F (PM2Y ₁ ) of the previous second register mark and the FF camera-print point distance L2. Position (print point arrival position of the virtual substrate) PI ₀ is obtained and written in the memory M40 (step S197). In this example, the printing point arrival position one sheet prior to the printing point arrival position PI ₁ of the first substrate # 1 is obtained as the printing point arrival position PI ₀ of the virtual substrate.

Further, the CPU 201 reads the X-direction shift amount Δx2 (Δx2 ₍₁₎ ) of the second register mark from the memory M34, and uses the read second shift amount Δx2 ₍₁₎ of the second register mark as the first second. The shift amount M2Δx in the X direction between the register marks is written in the memory M41 (see step S198, FIG. 82 (a), FIG. 86). Then, 1 is added to the count value M in the memory M32 to set M = 2 (step S199), and the process returns to step S178 (FIG. 27).

When returning to step S178, the CPU 201 proceeds to steps S186 (FIG. 27) through steps S179 to S185, and confirms whether the count value M in the memory M32 is M = 2 or not. In this case, since the count value M in the memory M32 is set to M = 2 in the previous step S199 (YES in step S186), the CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (step S186). S200), and the count value is read from the impression cylinder rotation phase detection counter 210 (step S201), and the current web is calculated from the count value of the counter 213 for counting the number of rotations of the printing press and the count value of the impression cylinder rotation phase detection counter 210. The unwinding length l of 4 is obtained (step S202). Then, the printing point arrival position PI ₀ of the virtual substrate in the memory M40 is read (step S203), and whether the current unwinding length l of the web 4 has reached the printing point arrival position PI ₀ of the virtual substrate. It is confirmed whether or not (FIG. 28: Step S204).

In this case, the unwinding length l of the web 4 is just after the _first imaging position PFF ₁ of the FF camera and has not yet reached the printing point arrival position PI ₀ of the virtual substrate (NO in step S204). ), the routine proceeds to step S211 (FIG. 29) reads the image pickup position PFF ₁ of the FF camera from the first address position of the memory M16.

[Initial strict rotation phase adjustment of the plate cylinder and rubber cylinder (second registration)]
In the next step 212, the CPU 201 checks whether or not the unwinding length l of the web 4 is at the imaging position PFF ₁ of the FF camera. Here, the CPU 201 has already passed the imaging position PFF ₁ of the FF camera. . Therefore, the CPU 201 proceeds to step S213 (FIG. 30) in response to NO in step S212.

In this case, the CPU 201 continues to steps S213 (FIG. 30) to S232 (until the arrival at the imaging position PFF ₂ (described later) of the next FF camera of the web 4 unwinding length 1 is confirmed in step S212. The processing operation of FIG. 32) is repeated. In the processes of steps S213 to S232, the initial strict rotation phase of the plate cylinder and the rubber cylinder is adjusted. The initial precise rotation phase adjustment of the plate cylinder / rubber cylinder is performed as follows.

The CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 30: Step S213), and obtains the current rotation phase ψ _R of the impression cylinder from the read count value of the impression cylinder rotation phase detection counter 210. (Step S214). Then, the amount of displacement Δy2 of the second register mark in the Y direction is read from the memory M35 (step S215), and the amount of displacement Δy2 of the second register mark in the Y direction is added to the current rotational phase ψ _R of the impression cylinder to correct it. The current rotation phase ψ _R ′ of the impression cylinder is obtained (step S216).

Then, the CPU 201 obtains the rotation phase φm of the plate cylinder / rubber cylinder that should be based on the corrected current rotation phase ψ _R ′ of the impression cylinder (step S217), and counts from the counter 217 for detecting the plate cylinder / rubber cylinder rotation phase. Is read (step S218), and the current rotation phase φ _R of the plate cylinder / rubber cylinder is obtained from the read count value of the plate cylinder / rubber cylinder rotation phase detection counter 217 (step S219). Then, the current rotation phase φ _R of the plate cylinder / rubber cylinder is subtracted from the rotation phase φm of the plate cylinder / rubber cylinder obtained in step S217 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. The obtained current phase difference Δφ _R of the plate cylinder / rubber cylinder is written in the memory M26 (FIG. 31: step S220).

Then, CPU 201 obtains the current absolute value of the rotational phase difference [Delta] [phi _R of the current plate cylinder, blanket cylinder from the rotational phase difference [Delta] [phi _R of the plate cylinder, blanket cylinder obtained in step S220 (step S221), the memory M42 Then, the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder is read (step S222), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is the rotational phase difference between the plate cylinder and the rubber cylinder. It is confirmed whether or not it is equal to or smaller than the second allowable value α2 (step S223). In the present embodiment, the second allowable value α2 is smaller than the first allowable value α1 used in the initial coarse rotation phase adjustment (first registration) of the plate cylinder / rubber cylinder (α2 < It is defined as α1).

If the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is not less than or equal to the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder (NO in step S223), the CPU 201 A correction value conversion table of the current rotational phase difference / rotational speed of the plate cylinder / rubber cylinder is read from the memory M29 (step S224), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M26 (step S224). S225) Using the current rotational phase difference-rotational speed correction value conversion table of the plate cylinder / rubber cylinder, the rotational speed correction value ΔV is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder (step S226). ).

  The CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S227), and the rotation speed correction value ΔV of the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor is read. Is added to obtain the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor (step S228), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor is determined as the plate cylinder / rubber cylinder. The data is output to the drive motor driver 215 via the D / A converter 218 (step S229), and the process returns to step S178 (FIG. 24) to repeat the same operation.

As a result, the rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted, and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is the second tolerance of the rotational phase difference of the plate cylinder / rubber cylinder. The value α2 or less is adjusted.

When the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder becomes equal to or less than the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder (FIG. 31: YES in step S223), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 32: Step S230), and the read standard rotation speed VPr of the plate cylinder / rubber cylinder driving motor is read as the printing cylinder / rubber. The data is output to the drum driver motor driver 215 via the D / A converter 218 (step S231), and “1” is written in the memory M5 as a value indicating that the correction of the phase deviation by the second register mark is completed (step S231). S232).

CPU201 until unwinding length l of the web 4 has reached the imaging position PFF ₂ of FF camera, but repeats the processing operation in steps S213～S232, the current rotational phase difference Δφ of the plate cylinder, blanket cylinder in step S223 _If the absolute value of _R does not fall below the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder, the process does not proceed to steps S230 to S232. In this case, “2” is still written in the memory M5 as a value indicating that the correction of the phase deviation by the second register mark is not completed.

[Adjusting the position of the plate cylinder in the X direction (left and right direction)]
The CPU 201 repeats the processing operation of steps S213 to S232 while returning to step S178 (FIG. 24). During this processing operation, the unwinding length l of the web 4 reaches the printing point arrival position PI ₀ of the virtual substrate. If it is confirmed (FIG. 28: YES in step S204), the rotational speed VIr of the reference impression cylinder drive motor is read from the memory M2 (step S205), and the Y-direction reference distance M2LYr between the second register marks is read from the memory M45. (Step S206), and passes the printing point I of the substrate between the second register marks from the read rotational speed VIr of the reference impression cylinder driving motor and the Y-direction reference distance M2LYr between the second register marks. seek time as a second register mark between transit time t _M2, the transit time t _M2 between the second register mark Write to memory M52 (step S207).

Then, the CPU 201 reads the X-direction deviation amount M2Δx (Δx2 ₍₁₎ ) between the second register marks from the memory M41 (step S208), and steps the X-direction deviation amount M2Δx between the read second register marks. The rotation speed VRc of the X-direction registration motor between the second register marks is obtained by dividing by the second register mark passing time t _M2 obtained in S207 (step S209), and between the obtained second register marks. The rotational speed VRc (VRc = M2Δx / t _M2 ) of the X direction registration motor is output to the X direction registration motor driver 220 via the D / A converter 222 (step S210).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) obtained in step S210, and the X-direction deviation amount M2Δx (Δx2 ₍₁₎ ) between the second register marks. The position of the plate cylinder 1 in the X direction (left-right direction) starts to be continuously adjusted at a moving speed VRc corresponding to the above.

Further, when the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PWG _6next of the next WG camera during this processing operation (FIG. 24: YES in step S182), the deviation amount detection device An imaging command of the WG camera is transmitted to 300 (FIG. 33: step S233), and a response from the deviation amount detection device 300 is awaited (step S234). The CPU 301 of the deviation amount detection apparatus 300 receives an imaging command of the WG camera from the drive control apparatus 200, images the printed material on the web 4 being conveyed by the WG camera 304, and performs the first register in the same manner as described above. The amount of mark deviation is detected.

  When the CPU 201 of the drive control device 200 receives the displacement amount Δx1 in the X direction and the displacement amount Δy1 in the Y direction of the first register mark from the displacement amount detection device 300 (YES in step S234), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M11 and M12 (step S235), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S236).

Then, the CPU 201 reads the WG camera imaging position PWG _6next from the memory M14 (step S237), and reads the first register mark displacement amount Δy1 in the Y direction from the memory M12 (step S238), and WG camera imaging position PWG _6next. Further, the current imaging position (imaging position of the WG camera) PWG ₆ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained imaging position PWG ₆ of the WG camera is overwritten in the memory M14. (Step S239).

Note that the current original imaging position PWG ₆ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. And the imaging timing of the third register mark in the FB camera.

Further, CPU 201 from the memory M15 read the WG camera -FF camera distance L1 (step S240), from the WG camera imaging position PWG ₆ and WG camera -FF inter-camera distance L1 calculated in step S239 of the next FF camera obtains an imaging position PFF _6, it writes the image pickup position PFF ₆ of the determined next FF camera as the imaging position of the latest FF camera memory M49 (step S241).

Further, the CPU 201 reads the WG camera-FB camera distance L3 from the memory M17 (step S242), reads the count value N = 6 in the memory M13 (step S243), and obtains the imaging position PWG of the WG camera obtained in step S239. seeking ₆ and WG camera -FB camera distance imaging positions PFB ₆ of the next FB camera than L3, writes the image pickup position PFB ₆ of the determined next FB camera N = 6 th address location of the memory M18 (Fig. 34: Step S244, see FIG. 78 (c)).

Then, read the reference distance M1Lr between the first register mark from the memory M19 (step S245), the reference distance next WG camera imaging than M1Lr between WG camera imaging position PWG ₆ and first register mark obtained in step S239 The position PWG _7next is obtained and overwritten in the memory M14 (step S246).

Then, the count value K in the memory M51 is set to K = 2 (step S247), and the imaging position PFF ₂ (see FIG. 77B) of the second FF camera is read from the second address position in the memory M16. overwrites the imaging position PFF ₂ of the read second FF camera K-1 = 1 th address location (see step S248, FIG. 77 (c)).

Then, 1 is added to the count value K in the memory M51 to set K = 3 (step S249), and the processes in steps S248 to S250 are repeated until the count value K becomes K = 6 in step S250. As a result, as shown in FIG. 77C, the imaging positions PFF _{2 to} PFF ₅ of the FF camera in the memory M16 are shifted laterally and written to the first to fourth address positions.

CPU201 When the count value K is K = 6 (YES in step S250), reads the imaging position PFF ₆ of the latest FF camera written in the memory M49, the imaging position of the read latest FF camera PFF ₆ Is written in the fifth address position in the memory M16 (see step S251, FIG. 77 (d)). Then, 1 is added to the count value N in the memory M13 to set N = 7 (step S252), the process returns to step S178 (FIG. 24), steps S178 to S182, S183 to S186 (FIGS. 25 and 27), and S200. Through S211 (FIGS. 28 and 29), the process proceeds to step S212, and the processing operations of steps S213 (FIG. 30) to S232 (FIG. 32) are continued. In this case, in step S211 (FIG. 29), the imaging position PFF ₂ (see FIG. 77 (d)) of the FF camera written in the first address position of the memory 16 is read.

CPU201 during this processing operation, when the length l unwinding of the web 4 to confirm that it has reached the imaging position PFF ₂ of FF camera (Figure 29: YES in step S212), the value written in the memory M5 Reading (step S253), it is confirmed whether or not the value written in the memory M5 is “1” (step S254). If the value written in the memory M5 is not “1” (NO in step S254), the process returns to step S106 (FIG. 15), but if the value written in the memory M5 is “1”. (YES in step S254), it is determined that the correction of the phase deviation by the second register mark has been completed.

In this way, in the present embodiment, after the position of the second register mark RM2 is detected from the image of the first substrate # 1 imaged by the FF camera 305 (point t3 shown in FIG. 71), the web 4 (t4 points shown in FIG. 71), plate cylinder, blanket cylinder in accordance with the position of the second register mark RM2 (Y direction position) until unwinding length l reaches the imaging position PFF ₂ of FF camera In the initial stage, the strict rotation phase adjustment (second registration) is performed.

Further, in the present embodiment, in conjunction with the second registration, from the time when the unwinding length l of the web 4 reaches the printing point arrival position PI ₀ of the virtual substrate, the interval between the second register marks is reached. The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed VRc corresponding to the amount of deviation M2Δx (Δx2 ₍₁₎ ) in the X direction. Thus, the displacement of the plate cylinder 1 in the X direction between the second register marks M2Δx until the unwinding length l of the web 4 reaches the printing point arrival position PI ₁ of the first substrate # 1. (Δx2 ₍₁₎ ) is moved little by little in the X direction (see FIG. 88), and the horizontal position of the plate mounted on the plate cylinder 1 and the horizontal position of the substrate # 1 are accurately matched. It becomes.

In this embodiment, the second registration is performed until the unwinding length l of the web 4 reaches the imaging position PFF ₂ of the FF camera (strict initial phase adjustment of the plate cylinder / rubber cylinder). However, as shown in FIG. 72 as a section from the point t2 to the point t3, the unwinding length l of the web 4 is at the printing point arrival position PI ₁ of the first substrate # 1 at the latest. In the meantime, the second registration may be completed.

[Image capture command of next FF camera to deviation detection device from drive control device]
If the CPU 201 determines that the correction of the phase deviation by the second register mark has been completed (FIG. 29: YES in step S254), the CPU 201 transmits an imaging command for the FF camera to the deviation amount detection device 300 (FIG. 35). Step S255), waiting for transmission of the displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction of the second register mark from the displacement amount detection device 300 (step S256). The CPU 301 of the deviation amount detection device 300 receives an imaging command of the FF camera from the drive control device 200, images the printed material on the web 4 being conveyed by the FF camera 305, and performs the second register in the same manner as described above. The amount of mark deviation is detected.

[Detection of the position of the next second register mark in the drive control device (detection of the position of the subsequent second register mark)]
When the CPU 201 of the drive control device 200 receives the shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the second register mark transmitted from the shift amount detection device 300 (YES in step S256), the received first The shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the two register marks are written in the memories M34 and M35 (step S257), and a shift amount reception completion signal for the second register mark is transmitted to the shift amount detection device 300 (step S257). S258).

Then, CPU 201 reads the image pickup position PFF ₂ of FF camera than the first address position of the memory M16 (step S259), from the Y direction deviation amount Δy2 of the imaging position PFF ₂ and a second register mark FF second camera seeking Y direction position PM2Y ₂ registers mark, the determined second register mark in the Y-direction position PM2Y ₂ the Y-direction position of the second register mark in the rear (FF camera this second register which is detected from the captured image of The Y position of the mark) PM2Y _R is written in the memory M43 (see step S260, FIG. 79 (b), FIG. 86).

[Calculation of expansion / contraction ratio η1 between second register marks up to FF camera]
Then, the CPU 201 reads the Y-direction position PM2Y _F (PM2Y ₁ ) of the previous second register mark from the memory M36 (step S261), and the Y-direction position PM2Y _R (PM2Y) of the second register mark obtained in step S260. ₂ ), the Y-direction position PM2Y _F (PM2Y ₁ ) of the previous second register mark is subtracted to obtain the Y-direction distance M2LY ₁ between the second register marks, and the Y-direction distance M2LY between the obtained second register marks. ₁ is written in the first address position of the memory M44 (step S262: see FIGS. 83A and 86).

Then, CPU 201 reads the Y direction reference distance M2LYr between the second register mark from the memory M45 (Fig. 36: step S263), the Y direction distance M2LY ₁ in the Y direction reference distance between the second register mark obtained in step S262 By dividing by M2LYr, the expansion / contraction ratio η1 (η1 = M2LY ₁ / M2LYr) between the second register marks up to the FF camera is obtained and written in the memory M46 (step S264).

[Calculation of rotational speed VPc of plate cylinder / rubber cylinder driving motor between second register marks]
Next, the CPU 201 reads the rotational speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S265), and reads the FF-FB expansion / contraction rate η2 from the memory M6 (step S266). The reciprocal of the expansion ratio η1 between the second register marks up to the FF camera obtained in step S264 and the reciprocal of the expansion ratio η2 between FF and FB read in step S266 are obtained as the rotational speed VPr of the plate cylinder / rubber cylinder driving motor. Multiplication is performed to obtain the rotational speed VPc (VPc = VPr × 1 / η1 × 1 / η2) of the plate cylinder / rubber cylinder driving motor between the second register marks, and it is written in the memory M47 (step S267).

In this case, the expansion / contraction ratio η1 between the second register marks up to the FF camera is obtained as η1 = M2LY ₁ / M2LYr in step S264, and the expansion / contraction ratio η2 between FF-FB is the previous step S108 (FIG. 15). Since η2 = 1 is written in the memory M6, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is VPc = VPr × 1 / η1 × 1 = VPr × M2LYr / M2LY ₁ Desired.

[Calculation of X-direction Deviation M2Δx Between Second Register Marks]
Further, CPU 201 reads the displacement amount in the X direction of the second register mark from the memory _{M34 Δx2 (Δx2 (2))} , after the shift amount in the X direction of the read second register mark Δx2 _{(Δx2 (2))} Is written in the memory M48 as the X-direction position PM2X _R of the second register mark (see step S268, FIG. 80B, FIG. 86).

Then, the X-direction position PM2X _F (Δx2 ₍₁₎ ) of the second register mark before the memory M37 is read (step S269), and the X-direction position PM2X _R (Δx2 ₍ 2) of the second register mark after writing to the memory M48. ₂₎ The X-direction position PM2X _F (Δx2 ₍₁₎ ) of the previous second register mark is subtracted from 2) to obtain the X-direction shift amount M2Δx between the second register marks, and the X-direction between the second register marks Shift amount M2Δx (M2Δx = Δx2 ₍₂₎ −Δx2 ₍₁₎ ) is written in the memory M41 (see step S270, FIG. 82 (b), FIG. 86).

Then, the CPU 201 reads the Y-direction position PM2Y _R (PM2Y ₂ ) of the subsequent second register mark from the memory M43 (step S271), reads the FF camera-print point distance L2 from the memory M38 (step S272), and The printing point arrival position PI ₂ of the next printing material # ₂ is obtained from the Y-direction position PM2Y _R (PM2Y ₂ ) of the second register mark and the FF camera-printing point distance L2, and the next printing material # ₂ thus obtained is obtained. writing the print point arrival position PI ₂ in the second address position of the memory M39 (see step S273, FIG. 81 (b)). Then, 1 is added to the count value M in the memory M32 to set M = 3 (step S274), and the process proceeds to step S275 (FIG. 37).

[Adjustment of rotational speed of plate cylinder and rubber cylinder during printing and position of plate cylinder in X direction]
The CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (step S275), and also reads the count value from the counter 210 for detecting the pressure drum rotation phase (step S276). And the count value of the impression cylinder rotation phase detection counter 210 are used to determine the current unwinding length l of the web 4 (step S277).

Then, CPU 201 reads the image pickup position PWG _7NEXT of WG camera from the memory M14 (step S278), the unwinding length l of the current web 4 checks whether it has reached the imaging position PWG _7NEXT of WG camera ( Step S279). Further, it reads the imaging position PFF ₂ of FF camera than the first address position of the memory M16 (step S280), whether or not the unwinding length l of the current web 4 has reached the imaging position PFF ₂ of FF camera Confirmation is made (step S281).

Further, the printing point arrival position PI ₁ of the substrate is read from the first address position of the memory M39 (step S282), and the unwinding length l of the current web 4 becomes the printing point arrival position PI ₁ of the next substrate. It is confirmed whether or not it has been reached (step S283). Further, the imaging position PFB ₁ of the FB camera is read from the first address position of the memory M18 (step S284), and it is determined whether or not the current unwinding length l of the web 4 has reached the imaging position PFB ₁ of the FB camera. Confirmation is made (step S285).

[Achieving the print point arrival position]
In this example, the unwinding length l of the current web 4 has already passed the imaging position PFF ₂ of the FF camera, and the printing point arrival position PI ₁ <the imaging position PWG _{7next of the} FB camera <the imaging position PFB _{1 of the} FB camera. (See FIG. 71).

Therefore, when the CPU 201 confirms that the unwinding length l of the web 4 has reached the printing point arrival position PI ₁ (YES in step S283), that is, the arrival of the first substrate # 1 to the printing point I is reached. Upon confirmation, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is read from the memory M47 (FIG. 38: Step S286), and the plate cylinder / rubber cylinder driving between the read second register marks is read. The rotational speed VPc of the motor is output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (step S287).

In this case, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is obtained as VPc = VPr × 1 / η1 in the previous step S267 (FIG. 36), and η1 is the previous step. Since it is obtained as η1 = M2LY ₁ / M2LYr in S264 (FIG. 36), it corresponds to the expansion / contraction rate η1 obtained from the Y-direction distance M2LY ₁ between the first second register marks, that is, the first substrate # 1. The rotational speed of the plate cylinder / rubber cylinder driving motor is adjusted according to the expansion / contraction ratio η1 up to the FF camera.

Then, CPU 201 reads the rotational speed VIr of the impression cylinder drive motor of the reference from the memory M2 (step S288), reads the Y-direction distance M2LY ₁ between second register mark from the memory M44 (step S289), it this read Based on the rotational speed VIr of the reference impression cylinder driving motor and the Y-direction distance M2LY ₁ between the second register marks, the time required to pass the printing point I of the substrate between the second register marks is the time t between the second register marks. _Obtained as _M2 , and this second register mark passing time t _M2 is written in the memory M52 (step S290).

Then, the CPU 201 reads the amount of displacement M2Δx (Δx2 ₍₂₎ −Δx2 ₍₁₎ ) in the X direction between the second register marks from the memory M41 (step S291), and from the memory M7 in the X direction of the third register mark. The average deviation amount Δx3 _av is read (step S292), and the deviation amount M2Δx (Δx2 ₍₂₎ −Δx2 ₍₁₎ ) in the X direction between the second register marks is the average of the deviation amounts in the X direction of the third register marks. The value Δx3 _av is added to obtain the total deviation amount ΣΔx in the X direction and written to the memory M53 (step S293). In this case, since the average value Δx3 _av of the deviation amount in the X direction of the third register mark is set to 0 in the previous step S109 (FIG. 15), the total deviation amount ΣΔx in the X direction is obtained as ΣΔx = M2Δx.

Then, the CPU 201 divides the obtained total displacement amount ΣΔx in the X direction by the second register mark passage time t _M2 obtained in step S290, and rotates the rotational speed of the X direction registration motor between the second register marks. VRc is obtained (step S294), and the obtained rotation speed VRc (VRc = ΣΔx / t _M2 ) of the X-direction registration motor between the second register marks is supplied to the X-direction registration motor driver 220 as a D / A converter. The data is output via 222 (step S295), and the process returns to step S275 (FIG. 37).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = ΣΔx / t _M2 ) determined in step S294, and the total deviation amount ΣΔx (ΣΔx = M2Δx = X-direction determined in step S293). The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed corresponding to Δx2 ₍₂₎ −Δx2 ₍₁₎ ). That is, the amount of deviation in the X direction between the second register marks M2Δx = Δx2 ₍₂₎ −Δx2 ₍₁₎ from the point when the unwinding length l of the web 4 reaches the printing point arrival position PI ₁ of the substrate # 1. The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed according to the above.

Thus, until a length l unwinding of the web 4 reaches the printing point arrival position PI ₂ of next printing material # 2, the amount of deviation of the position of the plate cylinder 1 is X direction between the second register mark M2Δx (Δx2 ₍₂₎ −Δx2 ₍₁₎ ) is moved little by little in the X direction (see FIG. 89), and the horizontal position of the plate mounted on the plate cylinder 1 and the horizontal position of the substrate # 2 are determined. It will be precisely matched.

  In addition, printing of the substrate # 1 is started in a state where the position of the plate mounted on the plate cylinder 1 in the left-right direction and the position of the substrate # 1 in the left-right direction are accurately matched, and printing of the substrate # 1 is performed. Among them, since the position of the plate cylinder 1 is continuously moved in the X direction (left and right direction) at the moving speed VRc, the positional deviation generated in the substrate # 1 due to the meandering of the web 4 being conveyed is also corrected. It will be a thing.

[Arrival to the imaging position of the WG camera]
When the CPU 201 _confirms that the unwinding length l of the web 4 has reached the imaging position PWG _7next of the WG camera (FIG. 37: YES in step S279), the CPU 201 transmits an imaging command of the WG camera to the deviation amount detection device 300. (FIG. 39: Step S296). Then, when the deviation amount Δx1 in the X direction and the deviation amount Δy1 in the Y direction of the first register mark of the printed material imaged from the deviation amount detection device 300 are transmitted (YES in step S297), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M11 and M12 (step S298), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S299).

Then, the CPU 201 reads the imaging position PWG _7next of the WG camera from the memory M14 (step S300), reads the displacement amount Δy1 of the first register mark in the Y direction from the memory M12 (step S301), and captures the imaging position PWG _{7next of the} WG camera. Further, the current imaging position (imaging position of the WG camera) PWG ₇ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained imaging position PWG ₇ of the WG camera is overwritten in the memory M14. (Step S302).

Note that the current original imaging position PWG ₇ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. And the imaging timing of the third register mark in the FB camera.

Further, CPU 201 from the memory M15 read the WG camera -FF camera distance L1 (step S303), from the WG camera imaging position PWG ₇ and WG camera -FF inter-camera distance L1 calculated in step S302 of the next FF camera obtains an imaging position PFF _7, it writes the image pickup position PFF ₇ of the determined next FF camera as the imaging position of the latest FF camera memory M49 (step S304).

Further, CPU 201 reads the WG camera -FB camera distance L3 from the memory M17 (Fig. 40: step S305), in obtained WG camera follows from the imaging position PWG ₇ and WG camera -FB inter-camera distance L3 in step 302 FB camera obtains an image pickup position PFB ₇ of writes imaging position PFB ₇ of the determined next FB camera as the imaging position of the latest FB camera memory M50 (step S306).

Then, read the reference distance M1Lr between the first register mark from the memory M19 (step S307), the reference distance next WG camera imaging than M1Lr between imaging positions PWG ₇ and first register marks of WG camera obtained in step S302 The position PWG _8next is obtained and overwritten in the memory M14 (step S308).

Then, the CPU 201 sets the count value K in the memory M51 to K = 2 (step S309), and the image pickup position PFF ₃ of the second FF camera from the second address position in the memory M16 (see FIG. 77 (d)). ) reads, overwrites the image pickup position PFF ₃ of the read second FF camera K-1 = 1 th address location reference (step S310, the FIG. 77 (e)).

Then, 1 is added to the count value K in the memory M47 to set K = 3 (step S311), and the processes in steps S310 to S312 are repeated until the count value K becomes K = 6 in step S312. Thus, as shown in FIG. 77 (e), the imaging position PFF ₃ ~PFF ₆ of FF camera in the memory M16 is shifted laterally, are written to the 1-4-th address location.

CPU201 When the count value K is K = 6 (YES in step S312), reads the imaging position PFF ₇ of the latest FF camera written in the memory M49, the imaging position of the read latest FF camera PFF ₇ Is written in the fifth address position of the memory M16 (see FIG. 41: step S313, FIG. 77 (f)). Then, the count value N in the memory M13 is read (step S314), and it is checked whether or not the read count value N is N = 7 (step S315).

In this case, since it is N = 7 (YES in step S315), CPU 201 from the memory M50 reads the imaging position PFB ₇ latest FB camera, the imaging position PFB ₇ latest FB camera memory M18 read the Write to the seventh address position (step S316, see FIG. 78 (d)). Then, 1 is added to the count value N in the memory M13 to set N = 8 (step S317), and the process returns to step S275 (FIG. 37).

[Arrival to the imaging position of the FB camera]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFB ₁ of the FB camera (FIG. 37: YES in step S285), the CPU 201 transmits an imaging command for the FB camera to the deviation amount detection device 300. (FIG. 42: Step S323). When receiving the deviation amount Δx3 in the X direction and the deviation amount Δy3 in the Y direction of the third register mark of the imaged printed material from the deviation amount detection device 300 (YES in step S324), the received third register mark is received. The X-direction deviation amount Δx3 and the Y-direction deviation amount Δy3 are written in the memories M55 and M56 (step S325), and a deviation amount reception completion signal for the third register mark is transmitted to the deviation amount detection device 300 (step S326).

[Image capture of printed matter by FB camera (detection of shift amount of third register mark by shift amount detection device)]
When an imaging command for the FB camera is sent from the drive control device 200 (FIG. 64: YES in step S493), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the FB camera 306 (step S494). Thereby, on the web 4 on which the FB camera 306 is conveyed at the timing when the imaging command of the FB camera is sent, that is, when the unwinding length l of the web 4 reaches the imaging position PFB ₁ of the FB camera. An image of the substrate to be printed is taken.

  Then, the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 65: step S499), reads the number of pixels i in the left-right direction of the FB camera in the memory M94 (step S500), and the count value in step S501. The processing operations in steps S498 to S501 are repeated until X exceeds the number i of pixels in the left-right direction of the FB camera.

  If the count value X exceeds the number i of pixels in the horizontal direction of the FB camera (YES in step S501), 1 is added to the count value Y in the memory M71 (step S502), and the top and bottom of the FB camera in the memory M95. The pixel number j in the direction is read (step S503), and the processing operations in steps S497 to S504 are repeated until the count value Y exceeds the pixel number j in the vertical direction of the FB camera in step S504.

  As a result, imaging data of i × j pixels from the FB camera 306 is stored in the memory M93. Here, as shown in FIG. 76A, it is assumed that the imaging data of the area including the third register mark RM3 of the printing object # 1 is stored in the memory M93 as imaging data of i × j pixels.

  In the memory M96, as shown in FIG. 76B, p × q pixel data of the third register mark is stored as pattern matching data. The vertical direction of the FB camera 306 is the flow direction of the web 4, and the left-right direction of the FB camera 306 is a direction orthogonal to the flow direction of the web 4.

  Next, the CPU 301 sets the count value Y in the memory M71 to 1 (FIG. 66: step S505), sets the count value X in the memory M72 to 1 (step S506), and sets the count value N in the memory M76 to 1 ( In step S507), the count value M in the memory M77 is set to 1 (step S508).

  Then, the imaging pixel data of the FB camera at the address position (X + M−1, Y + N−1) in the memory M93 is read (step S509), and the third register mark at the address position (M, N) in the memory M96 is read. The pixel data is read (step S510). The read pixel data of the FB camera at the address position (X + M-1, Y + N-1) in the read memory M93 and the (M, N) address position in the memory M96. It is confirmed whether or not the pixel data of the 3 register mark coincides (see step S511, FIGS. 76A and 76B).

  Here, the imaging pixel data of the FB camera at the address position (X + M−1, Y + N−1) in the memory M93 and the pixel data of the third register mark at the address position (M, N) in the memory M96 are identical. If not (NO in step S511), any pixel data of the imaging data of the FB camera 306 from the address (X, Y) to the address (X + p-1, Y + q-1) at that time is stored in the third register. Unlike the mark pixel data, there is no third register mark in the range starting from the address (X, Y), so the CPU 301 adds 1 to the count value X in the memory M72 (FIG. 67: step S512). ) Read the left-right pixel number i of the FB camera in the memory M94 and the left-right pixel number p of the third register mark in the memory M97 (step). S513, S514), in step S515 until the count value X exceeds "i-p + 1", and repeats the processing operation in steps S507～S515.

  If the count value X exceeds “ip + 1” during this processing operation (YES in step S515), it means that the left and right ends of the imaging data of the FB camera 306 have been exceeded, so the CPU 301 stores the data in the memory M71. 1 is added to the count value Y (step S516), and the vertical pixel number j of the FB camera in the memory M95 and the vertical pixel number q of the third register mark in the memory M98 are read (steps S517 and S518). ), The processing operation of steps S506 to S519 is repeated until the count value Y exceeds “j−q + 1” in step S519.

  During this processing operation, the imaging pixel data of the FB camera at the address position (X + M−1, Y + N−1) in the memory M93 and the pixel data of the third register mark at the address position (M, N) in the memory M96 Are confirmed (FIG. 66: YES in step S511), the CPU 301 adds 1 to the count value M in the memory M77 (FIG. 68: step S521), and the third register from the memory M97. The number of pixels p in the left-right direction of the mark is read (step S522), and the processing operations of steps S509 to S523 are repeated until the count value M exceeds the number of pixels p in the left-right direction of the third register mark in step S523.

  When the count value M exceeds the number p of pixels in the left-right direction of the third register mark (YES in step S523), 1 is added to the count value N in the memory M76 (step S524), and the third register mark is read from the memory M98. The number of pixels q in the vertical direction is read (step S525), and the processing operations in steps S508 to S526 are repeated until the count value N exceeds the number of pixels q in the vertical direction of the third register mark in step S526.

  In this manner, the CPU 301 performs pattern matching of the pixel data of the p × q third register mark in the memory M96 with respect to the imaging data of the i × j pixel in the memory M93, and the count value N is the third value. When the number of pixels q in the vertical direction of the register mark is exceeded (YES in step S526), the address (X + p-1, Y + q-1) from the (X, Y) address of the imaging data of the i × j pixel in the memory M93. It is determined that the pixel data of the p × q third register mark in the memory M96 is included in the range up to. That is, it is determined that the third register mark RM3 is included in the image captured by the FB camera 306.

  If the count value Y exceeds “j−q + 1” in step S519 (FIG. 67) (YES in step S519), it means that the edge of the image data of the FB camera 306 has been exceeded, and the CPU 301 Determines that the third register mark is not included in the image captured by the FB camera 306, and displays an error message “No third register mark” on a display (not shown) (step S520).

  When CPU 301 determines that the third register mark is included in the image captured by FB camera 306 (YES in step S526), CPU 301 reads count value X in memory M72 at that time (step S527). The measurement position in the X direction of the third register mark is calculated from the count value X and written in the address position in the X direction in the memory M99 (FIG. 69: step S528). Then, the reference position in the X direction of the third register mark is read from the address position in the X direction of the memory M100 (step S529), and the reference position in the X direction of the third register mark is determined from the measurement position of the third register mark in the X direction. Subtraction is performed to determine the amount of deviation Δx3 in the X direction of the third register mark (see FIG. 76 (c)), and the amount of deviation Δx3 in the X direction of the third register mark is written to the address position in the X direction of the memory M101. (Step S530).

  Further, the CPU 301 reads the count value Y in the memory M71 at that time (step S531), calculates the measurement position in the Y direction of the third register mark from the read count value Y, and the Y-direction address in the memory M99. The position is written (step S532). Then, the Y-direction reference position of the third register mark is read from the Y-direction address position of the memory M100 (FIG. 70: Step S533), and the Y-direction of the third register mark is measured from the Y-direction measurement position of the third register mark. The reference position is subtracted to determine the amount of deviation Δy3 in the Y direction of the third register mark (see FIG. 76C), and the amount of deviation Δy3 in the Y direction of the third register mark thus obtained is determined as the Y direction address of the memory M101. The position is written (step S534).

  Then, the CPU 301 transmits to the drive control device 200 the X-direction displacement amount Δx3 and the Y-direction displacement amount Δy3 of the third register mark written in the memory M101 (step S535). Then, upon receipt of the third register mark shift amount reception completion signal from the drive control device 200 (YES in step S536), the third register mark shift amount Δx3 in the X direction and the shift in the Y direction to the drive control device 200 are detected. The transmission of the amount Δy3 is stopped (step S537), and the process returns to step S401 (FIG. 51) to prepare for the next imaging command of the WG camera from the drive control device 200.

[Detection of the position of the third register mark in the drive control device (detection of the position of the subsequent third register mark)]
When the CPU 201 of the drive control device 200 receives the shift amount Δx3 in the X direction and the shift amount Δy3 in the Y direction of the third register mark transmitted from the shift amount detection device 300 (FIG. 42: YES in step S324), The received X register direction shift amount Δx3 and Y direction shift amount Δy3 of the received third register mark are written in the memories M55 and M56 (step S325), and the shift amount detection device 300 transmits a shift amount reception completion signal of the third register mark. (Step S326).

Then, the CPU 201 reads the count value L in the memory M33 (step S327), and checks whether the count value L is L = 1 (step S328). In this case, since the count value L is L = 1 (YES in step S328), the CPU 201 determines the imaging position PFB _{1 of the} FB camera from the first address position of the memory M18 (see FIG. 78 (d)). read (step S329), obtains the position PM3Y ₁ in the Y direction of the third register mark from the Y direction deviation amount Δy3 imaging position PFB ₁ and the third register mark FB camera, Y direction of the third register mark the determined third register mark position in the Y direction after the position PM3Y ₁ of (FF camera detected third register mark Y direction current position of the captured image) is written in the memory M57 as PM3Y _R (step S330, FIG. 84 (a)). Further, it reads the deviation amount in the X direction of the third register mark from the memory _{M55 Δx3 (Δx3 (1))} , and writes the L = 1 th address location of the memory M59 as the X-direction position PM3X ₁ of the third register mark (step S331, see FIG. 85 (a)). Then, 1 is added to the count value L in the memory M33 to set L = 2 (FIG. 43: step S340), and the process returns to step S275 (FIG. 37).

[Arrival to the imaging position of the FF camera]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFF ₃ of the FF camera (FIG. 37: YES in step S281), the CPU 201 transmits an imaging command of the FF camera to the deviation amount detection device 300. (FIG. 47: Step S362). Then, when the shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the second register mark of the imaged printed material from the shift amount detection device 300 are received (YES in step S363), the received second register mark is received. The X-direction displacement amount Δx2 and the Y-direction displacement amount Δy2 are written in the memories M34 and M35 (step S364), and a displacement amount reception completion signal for the second register mark is transmitted to the displacement amount detection device 300 (step S365).

[Detection of the position of the next second register mark (detection of the position of the next second register mark)]
Then, the CPU 201 reads the position PM2Y _R (PM2Y ₂ ) (see FIG. 79B) of the second register mark after being written in the memory M43 in the Y direction, and stores the previous second register mark in the memory M36. It is written as the Y-direction position PM2Y _F (see step S366, FIG. 79 (c)). Further, the X-direction position PM2X _R (Δx2 ₍₂₎ ) (see FIG. 80B ₎ of the second register mark after being written in the memory M48 is read, and the X of the previous second register mark is read into the memory M37. Write as the direction position PM2X _F (see step S367, FIG. 80 (c)).

Then, the imaging position PFF ₃ (see FIG. 77 (f)) of the FF camera is read from the first address position of the memory M16 (step S368), and the imaging position PFF ₃ of the FF camera and the second register mark are shifted in the Y direction. The Y-direction position PM2Y ₃ of the current second register mark is obtained from the amount Δy2, and the obtained Y-direction position PM2Y ₃ of the second register mark is written in the memory M43 as the Y-direction position PM2Y _R of the subsequent second register mark ( Step S369, see FIG. 79 (d))). Then, the count value M in the memory M32 is read (step S370), and it is confirmed whether or not the count value M is M = 3 (FIG. 48: step S371). In this case, since the count value M is M = 3 (YES in step S371), the CPU 201 proceeds to step S372.

[Calculation of expansion / contraction ratio η1 between second register marks up to FF camera]
In step S372, the CPU 201 reads the Y-direction position PM2Y _F (PM2Y ₂ ) (see FIG. 79D) of the previous second register mark from the memory M36. Then, the Y direction position PM2Y _R (PM2Y ₃ ) of the subsequent second register mark is read from the memory M43 (step S373), and the second register mark before the Y direction position PM2Y _R (PM2Y ₃ ) of the subsequent second register mark is read. The Y-direction position PM2Y _F (PM2Y ₂ ) of the mark is subtracted to obtain the Y-direction distance M2LY ₂ between the next second register marks (see FIG. 86), and the Y-direction distance between the obtained next second register marks. M2LY ₂ is written into the second address position of the memory M44 (see step S374, FIG. 83 (b)).

Then, CPU 201 reads the Y direction reference distance M2LYr between the second register mark from the memory M45 (step S375), divides the Y-direction distance M2LY ₂ between the second register mark obtained in step S374 in the Y direction reference distance M2LYr Then, the expansion / contraction ratio η1 (η1 = M2LY ₂ / M2LYr) between the next second register marks up to the FF camera is obtained and written in the memory M46 (step S376).

[Calculation of Rotational Speed VPc of Plate Cylinder / Rubber Cylinder Driving Motor Between Next Second Register Marks]
Next, the CPU 201 reads the expansion rate η2 between FF and FB from the memory M6 (step S377), reads the rotational speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S378), and sets the reference speed. The reciprocal of the expansion ratio η1 between the second register marks up to the FF camera obtained in step S376 and the reciprocal of the expansion ratio η2 between FF and FB read in step S377 are obtained as the rotational speed VPr of the plate cylinder / rubber cylinder driving motor. Multiplication is performed to obtain a rotational speed VPc (VPc = VPr × 1 / η1 × 1 / η2) of the plate cylinder / rubber cylinder driving motor between the second register marks, and it is written in the memory M47 (step S379).

In this case, the expansion / contraction ratio η1 between the second register marks up to the FF camera is obtained as η1 = M2LY ₂ / M2LYr in the previous step S376, and the expansion / contraction ratio η2 between the FF-FB is determined in the previous step S108 (FIG. 15), since η2 = 1 is written in the memory M6, the rotation speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is VPc = VPr × 1 / η1 × 1 = VPr × M2LYr / M2LY. Required as ₂ .

Then, CPU 201 reads the displacement amount in the X direction of the second register mark from the memory _{M34 Δx2 (Δx2 (3))} , written in the memory M48 as the X-direction position PM2X _R of the second register mark in the rear (FIG. 49: step S380, see FIG. 80 (d)). Then, the X-direction position PM2X _F (Δx2 ₍₂₎ ) of the previous second register mark is read from the memory M37 (step S381), and the X-direction position PM2X _R (Δx2 ₍₃₎ ) of the subsequent second register mark is read before X direction position PM2X _F (Δx2 ₍₂₎ ) of the second register mark is subtracted to obtain an X direction deviation amount M2Δx between the second register marks, and an X direction deviation amount M2Δx ( M2Δx = Δx2 ₍₃₎ −Δx2 ₍₂₎ ) is written into the memory M41 (see step S382, FIG. 82 (c), and FIG. 86).

Then, the CPU 201 reads the printing point arrival position PI ₂ (see FIG. 81B) written in the second address position of the memory M39 and writes it in the first address position of the memory M39 (step S383, FIG. 81 (c)). Then, the Y-direction position PM2Y _R (PM2Y ₃ ) of the subsequent second register mark is read from the memory M43 (step S384, see FIG. 79 (d)), and the FF camera-print point distance L2 is read from the memory M38 (step S38). S385), the print point arrival position PI ₃ of the next substrate # ₃ is obtained from the Y-direction position PM2Y _R (PM2Y ₃ ) of the subsequent second register mark and the FF camera-print point distance L2, and the next The printing point arrival position PI ₃ of the substrate # 3 is written in the second address position of the memory M39 (see step S386, FIG. 81 (d)), and 1 is added to the count value M in the memory M32 to obtain M = 4. (Step S387), the process returns to step S275 (FIG. 37).

[Achieving the next printing point arrival position]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the next print point arrival position PI ₂ (FIG. 37: YES in step S283), that is, the next print # 1 to the print point I is reached. When the arrival is confirmed, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is read from the memory M47 (FIG. 38: Step S286), and the plate cylinder / rubber cylinder between the read second register marks. The rotational speed VPc of the driving motor is output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (step S287).

In this case, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is obtained as VPc = VPr × 1 / η1 in the previous step S379 (FIG. 48), and η1 is the previous step. Since it is obtained as η1 = M2LY ₂ / M2LYr in S376 (FIG. 48), it corresponds to the expansion / contraction rate η1 obtained from the Y-direction distance M2LY ₂ between the second register marks, that is, the FF of the next substrate # 2. The rotation speed of the plate cylinder / rubber cylinder driving motor is adjusted according to the expansion / contraction ratio η1 up to the camera.

Then, CPU 201 reads the rotational speed VIr of the impression cylinder drive motor of the reference from the memory M2 (step S288), reads the Y-direction distance M2LY ₂ between the second register mark from the memory M44 (step S289), it this read rotational speed VIr and second register marks between the Y-direction distance M2LY ₂ Metropolitan from a time through the printing point I of the substrate between the second register mark second register mark between transit time t of the reference pressure drum drive motor _Obtained as _M2 , and this second register mark passing time t _M2 is written in the memory M52 (step S290).

Then, the CPU 201 reads from the memory M41 the amount of displacement M2Δx (M2Δx = Δx2 ₍₃₎ −Δx2 ₍₂₎ ) in the X direction between the second register marks (step S291), and also reads the X of the third register mark from the memory M7. An average value Δx3 _{av of the} amount of deviation in the direction is read (step S292), and the amount of deviation in the X direction of the third register mark is calculated as the amount of deviation M2Δx (Δx2 ₍₃₎ −Δx2 ₍₂₎ ) in the X direction between the second register marks. adding the average value .DELTA.x3 _av, determine the total deviation amount ΣΔx in the X direction, written in the memory M53 (step S293). In this case, since the average value Δx3 _av of the deviation amount in the X direction of the third register mark is set to 0 in the previous step S109 (FIG. 15), the total deviation amount ΣΔx in the X direction is obtained as ΣΔx = M2Δx.

Then, the CPU 201 divides the obtained total displacement amount ΣΔx in the X direction by the second register mark passage time t _M2 obtained in step S290, and rotates the rotational speed of the X direction registration motor between the second register marks. VRc is obtained (step S294), and the obtained rotational speed VRc (VRc = M2Δx / t _M2 ) of the X-direction registration motor between the second register marks is supplied to the X-direction registration motor driver 220 as a D / A converter. The data is output via 222 (step S295), and the process returns to step S275 (FIG. 37).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) determined in step S294, and the total deviation amount ΣΔx (ΣΔx = M2Δx = in the X direction determined in step S293). The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed corresponding to Δx2 ₍₃₎ −Δx2 ₍₂₎ ).

That is, the length l unwinding of the web 4 in the same manner as when it reaches the printing point reaches the position PI ₁ of the substrate # 1, the printing point of the length l unwinding of the web 4 is the substrate # 2 reaches the position PI _From the time point ₂ is reached, the position of the plate cylinder 1 in the X direction is continuously adjusted at a moving speed corresponding to the displacement amount M2Δx = Δx2 ₍₃₎ −Δx2 ₍₂₎ in the X direction between the second register marks. start.

[Arrival to the imaging position of the next WG camera]
When the CPU 201 _confirms that the unwinding length l of the web 4 has reached the imaging position PWG _8next of the WG camera (FIG. 37: YES in step S279), the CPU 201 transmits an imaging command of the WG camera to the deviation amount detection device 300. (FIG. 39: Step S296). Then, when the deviation amount Δx1 in the X direction and the deviation amount Δy1 in the Y direction of the first register mark of the printed material imaged from the deviation amount detection device 300 are transmitted (YES in step S297), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M11 and M12 (step S298), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S299).

Then, the CPU 201 reads the WG camera imaging position PWG _8next from the memory M14 (step S300), reads from the memory M12 the Y-direction shift amount Δy1 of the first register mark (step S301), and WG camera imaging position PWG _8next. Then, the current imaging position (imaging position of the WG camera) PWG ₈ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained imaging position PWG ₈ of the WG camera is overwritten in the memory M14. (Step S302).

Note that the current original imaging position PWG ₈ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. And the imaging timing of the third register mark in the FB camera.

Further, CPU 201 from the memory M15 read the WG camera -FF camera distance L1 (step S303), from the WG camera imaging position PWG ₈ and WG camera -FF inter-camera distance L1 calculated in step S302 of the next FF camera obtains an imaging position PFF _8, it writes the image pickup position PFF ₈ of the determined next FF camera as the imaging position of the latest FF camera memory M49 (step S304).

Further, CPU 201 reads the WG camera -FB camera distance L3 from the memory M17 (Fig. 40: step S305), in obtained WG camera follows from the imaging position PWG ₈ and WG camera -FB inter-camera distance L3 in step S302 FB camera obtains an image pickup position PFB ₈ of writes imaging position PFB ₈ of the determined next FB camera as the imaging position of the latest FB camera memory M50 (step S306).

Then, read the reference distance M1Lr between the first register mark from the memory M19 (step S307), the reference distance next WG camera imaging than M1Lr between imaging positions PWG ₈ and first register marks of WG camera obtained in step S302 The position PWG _9next is obtained and overwritten in the memory M14 (step S308).

Then, CPU 201 sets the count value K in the memory M51 as a K = 2 (step S309), reads the image pickup position PFF ₄ of the second FF camera from K = second address position of the memory M16 (Fig. 77 (f )), and overwrites the image pickup position PFF ₄ of the read second FF camera K-1 = 1 th address location (see step S310, the FIG. 77 (g)).

Then, 1 is added to the count value K in the memory M51 to set K = 3 (step S311), and the processes in steps S310 to S312 are repeated until the count value K becomes K = 6 in step S312. Thus, as shown in FIG. 77 (g), the image pickup position PFF ₄ ~PFF ₇ of FF camera in the memory M16 is shifted laterally, are written to the 1-4-th address location.

When the count value K becomes K = 6 (YES in step S312), the CPU 201 reads the latest imaging position PFF ₈ of the FF camera written in the memory M49, and reads the latest imaging position PFF ₈ of the FF camera. Is written in the fifth address position of the memory M16 (see FIG. 41: step S313, FIG. 77 (h)). Then, the count value N in the memory M13 is read (step S314), and it is checked whether or not the read count value N is N = 7 (step S315).

In this case, since N = 8 (NO in step S315), the CPU 201 sets the count value K in the memory M51 to K = 2 (step S318), and the second value from the second address position in the memory M18 is K = 2. The imaging position PFB ₂ (see FIG. 78 (d)) of the FB camera is read, and the read imaging position PFB ₂ of the second FB camera is overwritten to the K-1 = 1st address position (step S319, FIG. 78). (See (e)). Then, 1 is added to the count value K in the memory M51 to set K = 3 (step S320), and the processing of steps S319 to S321 is repeated until the count value K becomes K = 8 in step S321. Thereby, as shown in FIG. 78 (e), the imaging positions PFB _{2 to} PFB ₇ of the FB camera in the memory M18 are shifted laterally and written to the first to sixth address positions.

Then, 1 is added to the count value N in the memory M13 to set N = 9 (step S317), and the process returns to step S275 (FIG. 37).

[Achieving the imaging position of the next FB camera]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFB ₂ of the FB camera (FIG. 37: YES in step S285), the CPU 201 transmits an imaging command for the FB camera to the deviation amount detection device 300. (FIG. 42: Step S323). When receiving the deviation amount Δx3 in the X direction and the deviation amount Δy3 in the Y direction of the third register mark of the imaged printed material from the deviation amount detection device 300 (YES in step S324), the received third register mark is received. The X-direction deviation amount Δx3 and the Y-direction deviation amount Δy3 are written in the memories M55 and M56 (step S325), and a deviation amount reception completion signal for the third register mark is transmitted to the deviation amount detection device 300 (step S326).

Then, the CPU 201 reads the count value L in the memory M33 (step S327), and checks whether the count value L is L = 1 (step S328). In this case, since the count value L is set to L = 2 (NO in step S328), the Y-direction position PM3Y _R (PM3Y ₁ ) of the third register mark after the memory M57 (see FIG. 84A). Read and write to the memory M58 as the previous third register mark position PM3Y _F (see FIG. 44: step S332, FIG. 84B). Then, the imaging position PFB ₂ (see FIG. 78 (f)) of the FB camera is read from the first address position of the memory M18 (step S333), and the imaging position PFB ₂ of the FB camera and the third register mark are shifted in the Y direction. The Y direction position PM3Y ₂ of the third register mark is obtained from the amount Δy3, and written in the memory M57 as the Y direction position PM3Y _R of the subsequent third register mark (see step S334, FIG. 84 (c), see FIG. 87).

Then, the CPU 201 subtracts the Y-direction position PM3Y _F (PM3Y ₁ ) of the previous third register mark from the Y-direction position PM3Y _R (PM3Y ₂ ) of the subsequent third register mark, and the Y direction between the third register marks. The distance M3LY ₁ is obtained, and the obtained Y-direction distance M3LY ₁ between the third register marks is written in the memory M60 (step S335). Then, the Y-direction distance M2LY ₁ (see FIG. 83B) between the second register marks is read from the first address position of the memory M44 (step S336), and the Y-direction between the third register marks obtained in step S335 is read. distance M3LY ₁ was divided by the Y-direction distance M2LY ₁ between the second register mark, is written in the memory M6 seeking expansion ratio _{η2 (η2 = M3LY 1 / M2LY} 1) between FF-FB (step S337).

Then, the process proceeds to step S338, and it is confirmed whether or not the count value L is L ≧ 7. In this case, since the count value L is L = 2 (NO in step S338), the process proceeds to step S339, and the amount of deviation Δx3 (Δx3 ₍₂₎ ) in the X direction of the third register mark is read from the memory M55. written as X-direction positions PM3X ₂ registers mark L = 2-th address location of the memory M59 (Fig. 85 (b), see FIG. 87). Then, 1 is added to the count value L in the memory M33 to set L = 3 (step S340), and the process returns to step S275 (FIG. 37).

[Achieving the imaging position of the next FF camera]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFF ₄ of the FF camera (FIG. 37: YES in step S281), the CPU 201 transmits an imaging command for the FF camera to the deviation amount detection device 300. (FIG. 47: Step S362). Then, when the shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the second register mark of the imaged printed material from the shift amount detection device 300 are received (YES in step S363), the received second register mark is received. The X-direction displacement amount Δx2 and the Y-direction displacement amount Δy2 are written in the memories M34 and M35 (step S364), and a displacement amount reception completion signal for the second register mark is transmitted to the displacement amount detection device 300 (step S365).

[Detection of the position of the next second register mark (detection of the position of the next second register mark)]
Then, the CPU 201 reads the position PM2Y _R (PM2Y ₃ ) (see FIG. 79D) of the second register mark after being written in the memory M43 in the Y direction, and stores the previous second register mark in the memory M36. It is written as the Y-direction position PM2Y _F (see step S366, FIG. 79 (e)). Further, the X-direction position PM2X _R (Δx2 ₍₃₎ ) (see FIG. 80 (d)) of the second register mark after being written in the memory M48 is read, and the X of the previous second register mark is read into the memory M37. Writing as the direction position PM2X _F (see step S367, FIG. 80 (e)).

Then, the imaging position PFF ₄ (see FIG. 77 (h)) of the FF camera is read from the first address position in the memory M16 (step S368), and the imaging position PFF ₄ of the FF camera and the second register mark are shifted in the Y direction. The Y direction position PM2Y ₄ of the current second register mark is obtained from the amount Δy2, and the obtained Y direction position PM2Y ₄ of the second register mark is written in the memory M43 as the Y direction position PM2Y _R of the subsequent second register mark ( Step S369, see FIG. 79 (f)). Then, the count value M in the memory M32 is read (step S370), and it is confirmed whether or not the count value M is M = 3 (FIG. 48: step S371). In this case, since the count value M is M = 4 (YES in step S371), the CPU 201 proceeds to step S388 (FIG. 50).

[Calculation of expansion / contraction ratio η1 between second register marks up to FF camera]
In step S388, the CPU 201 reads the Y-direction distance M2LY ₂ (see FIG. 83 (b)) between the second register marks from the second address position of the memory M44 and writes it to the first address position (FIG. 83 (c). )reference). Then, the Y-direction position PM2Y _F (PM2Y ₃ ) (see FIG. 79F) of the previous second register mark is read from the memory M36 (step S389), and the Y-direction position PM2Y of the subsequent second register mark is read from the memory M43. _R (PM2Y ₄ ) is read (step S390), the Y-direction position PM2Y _F (PM2Y ₃ ) of the previous second register mark is subtracted from the Y-direction position PM2Y _R (PM2Y ₄ ) of the subsequent second register mark, and the next seeking Y-direction distance M2LY ₃ between the second register mark, writes the Y-direction distance M2LY ₃ between this which obtained the following second register mark in the second address position of the memory M44 (step S391, FIG. 83 (d )reference).

Then, CPU 201 reads the Y direction reference distance M2LYr between the second register mark from the memory M45 (step S392), divides the Y-direction distance M2LY ₃ between the second register mark obtained in step S391 in the Y direction reference distance M2LYr Then, the expansion / contraction ratio η1 (η1 = M2LY ₃ / M2LYr) between the next second register marks up to the FF camera is obtained and written in the memory M46 (step S393).

[Calculation of Rotational Speed VPc of Plate Cylinder / Rubber Cylinder Driving Motor Between Next Second Register Marks]
Next, the CPU 201 reads the expansion rate η2 between FF and FB from the memory M6 (step S394), reads the rotational speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S395), and sets the reference speed. The reciprocal number of the expansion ratio η1 between the second register marks up to the FF camera obtained in step S393 and the reciprocal number of the expansion ratio η2 between FF and FB read in step S394 are obtained as the rotational speed VPr of the plate cylinder / rubber cylinder driving motor. Multiplication is performed to obtain the rotational speed VPc (VPc = VPr × 1 / η1 × 1 / η2) of the plate cylinder / rubber cylinder driving motor between the second register marks, and it is written in the memory M47 (step S396).

In this case, the expansion ratio η1 between the second register marks up to the FF camera is obtained as η1 = M2LY ₃ / M2LYr in the previous step S393, and the expansion ratio η2 between FF-FB is the previous step S337 (FIG. 43), η2 = M3LY ₁ / M2LY ₁ , so that the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is VPc = VPr × 1 / η1 × 1 / η2 = VPr × It is calculated as (M2LYr / M2LY ₃ ) × (M2LY ₁ / M3LY ₁ ).

Then, CPU 201 may shift amount in the X direction of the second register mark from the memory M34 .DELTA.x2 reads (.DELTA.x2 _(4)), written in the memory M48 as the X-direction position PM2X _R of the second register mark in the rear (FIG. 49: step S380, see FIG. 80 (f)). Then, the X-direction position PM2X _F (Δx2 ₍₃₎ ) of the previous second register mark is read from the memory M37 (step S381), and the X-direction position PM2X _R (Δx2 ₍₄₎ ) of the subsequent second register mark is X direction position PM2X _F (Δx2 ₍₃₎ ) of the second register mark is subtracted to obtain an X direction deviation amount M2Δx between the second register marks, and an X direction deviation amount M2Δx ( M2Δx = Δx2 ₍₄₎ −Δx2 ₍₃₎ ) is written into the memory M41 (see step S382, FIG. 82 (d)).

Then, the CPU 201 reads the printing point arrival position PI ₃ (see FIG. 81D) written in the second address position of the memory M39 and writes it in the first address position of the memory M39 (step S383, FIG. 81 (e)). Then, the Y-direction position PM2Y _R (PM2Y ₄ ) of the subsequent second register mark is read from the memory M43 (see step S384, FIG. 79 (f)), and the FF camera-printing point distance L2 is read from the memory M38 (step S384). S385), the print point arrival position PI ₄ of the next substrate # ₄ is determined from the Y-direction position PM2Y _R (PM2Y ₄ ) of the second register mark and the FF camera-print point distance L2, and the calculated next The printing point arrival position PI ₄ of the substrate # 4 is written in the second address position of the memory M39 (see step S386, FIG. 81 (f)), and 1 is added to the count value M in the memory M32 to obtain M = 5. (Step S387), the process returns to step S275 (FIG. 37).

[Achieving the next printing point arrival position]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the next printing point arrival position PI ₃ (FIG. 37: YES in step S283), that is, the next printing object # 3 to the printing point I is reached. When the arrival is confirmed, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is read from the memory M47 (FIG. 38: Step S286), and the plate cylinder / rubber cylinder between the read second register marks. The rotational speed VPc of the driving motor is output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (step S287).

In this case, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is obtained as VPc = VPr × 1 / η1 × η2 in the previous step S396 (FIG. 50), and η1 is the previous one. It determined at step S391 (FIG. 50) as η1 = M2LY ₃ / M2LYr, since .eta.2 is obtained as η2 = M3LY ₁ / M2LY ₁ in the previous step S337 (FIG. 43), Y between the second register mark depending on the direction distance M2LY ₃ and stretch ratio η1 obtained from the third expansion ratio was determined from the Y-direction distance M3LY ₁ between register marks .eta.2, i.e. up to FF camera of the substrate # 3 to be subsequently printed The rotation speed of the plate cylinder / rubber cylinder driving motor is adjusted according to the expansion / contraction ratio η1 and the expansion / contraction ratio η2 between the FF camera and the FB camera of the printing object # 1 printed this time. The things.

Then, CPU 201 reads the rotational speed VIr of the impression cylinder drive motor of the reference from the memory M2 (step S288), reads the Y-direction distance M2LY ₃ between the second register mark from the memory M44 (step S289), it this read rotational speed VIr and second register marks between the Y-direction distance M2LY ₃ Metropolitan from a time through the printing point I of the substrate between the second register mark second register mark between transit time t of the reference pressure drum drive motor _Obtained as _M2 , and this second register mark passing time t _M2 is written in the memory M52 (step S290).

Then, the CPU 201 reads the amount of displacement M2Δx (M2Δx = Δx2 ₍₄₎ −Δx2 ₍₃₎ ) in the X direction between the second register marks from the memory M41 (step S291), and the X of the third register mark from the memory M7. The average value Δx3 _av of the direction deviation is read (step S292), and the amount of deviation in the X direction of the third register mark is calculated as the amount of deviation M2Δx (Δx2 ₍₄₎ −Δx2 ₍₃₎ ) in the X direction between the second register marks. adding the average value .DELTA.x3 _av, determine the total deviation amount ΣΔx in the X direction, written in the memory M53 (step S293). In this case, since the average value Δx3 _av of the deviation amount in the X direction of the third register mark is set to 0 in the previous step S109 (FIG. 15), the total deviation amount ΣΔx in the X direction is obtained as ΣΔx = M2Δx.

Then, the CPU 201 divides the obtained total displacement amount ΣΔx in the X direction by the second register mark passage time t _M2 obtained in step S290, and rotates the rotational speed of the X direction registration motor between the second register marks. VRc is obtained (step S294), and the obtained rotational speed VRc (VRc = M2Δx / t _M2 ) of the X-direction registration motor between the second register marks is supplied to the X-direction registration motor driver 220 as a D / A converter. The data is output via 222 (step S295), and the process returns to step S275 (FIG. 37).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) determined in step S294, and the total deviation amount ΣΔx (ΣΔx = M2Δx = in the X direction determined in step S293). The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed according to Δx2 ₍₄₎ −Δx2 ₍₃₎ ).

That is, the unwinding length l of the web 4 in the same manner as when it reaches the printing point arrival position PI ₂ of the substrate # 2, the print point reaches the position PI of the length l unwinding of the web 4 is the substrate # 3 _From the time point ₃ is reached, the position in the X direction of the plate cylinder 1 is continuously adjusted at a moving speed corresponding to the amount of deviation M2Δx = Δx2 ₍₄₎ −Δx2 ₍₃₎ in the X direction between the second register marks. start.

In this embodiment, the unwinding length l of the web 4 reaches the reference imaging position PWGr of the WG camera as shown in FIG. 71, and then PWG _2next → PWG _3next → PWG _4next → PWG _5next → PFF ₁ → PWG _6next → PFF ₂ → PI ₁ → PWG _7next → PFB ₁ → PFF ₃ → PI ₂ → PWG _8next → PFB ₂ → PFF ₄ → PI ₃ ... That is, after reaching the imaging position PFF ₂ of the FF camera, the position change of PI → PWG → PFB → PFF → PI is repeated. For this reason, in the flowchart shown in FIG. 37, every time the unwinding length l of the web 4 reaches the position confirmed in that step in the order of steps S283, S279, S285, and S281, the same processing as described above. The operation will be repeated.

  During the repetition of this processing operation, when the count value L becomes L = 7, the CPU 201 proceeds to step S349 (FIG. 45) according to YES in step S338 (FIG. 43) and NO in step S341 (FIG. 44). Then, the total value [Sigma] [Delta] x3 of the deviation amount in the X direction of the third register mark in the memory M61 is set to zero.

The count value K in the memory M51 is set to K = 1 (step S350), and the X-direction position PM3X1 of the _first third register mark is read from the K = 1st address position in the memory M59 (step S351, FIG. 85 (c)), that is, the amount of deviation Δx3 ₍₁₎ in the X direction of the first third register mark is read, and the total value ΣΔx3 of the amount of deviation in the X direction of the third register mark is read from the memory M61 (step S352), the X-direction displacement amount Δx3 ₍₁₎ of the first third register mark is added to the total value of the X-direction displacement amounts of the third register mark, and the total displacement amount of the third register mark in the X-direction The value ΣΔx3 is written in the memory M61 (step S353).

Then, the CPU 201 adds 1 to the count value K in the memory M51 to set K = 2 (step S354), and repeats the processing of steps S351 to S355 until the count value K becomes K = 7 in step S355. In this case, the process of step S339 (FIG. 43) performed each time the length 4 of the web 4 reaches the imaging position PFB of the FB camera causes the memory M59 to store the third register mark at the first to sixth address positions. X direction positions PMX ₁ (Δx3 ₍₁₎ ) to PMX ₆ (Δx3 ₍₆₎ ) in the X direction are written (see FIG. 85C). For this reason, by repeating the processing of steps S351 to S355, the memory M61 stores the third register mark in the X-direction shift amount Δx3 _{(1) to} Δx3 ₍ as the total value ΣΔx3 of the third register mark in the X direction. _The value obtained by adding ₆₎ is written.

When the count value K becomes K = 7 (YES in step S355), the CPU 201 reads the total amount ΣΔx3 of the shift amounts in the X direction of the third register mark written in the memory M61 (FIG. 46: step S356). The total value ΣΔx3 of the deviation amounts in the X direction of the read third register mark is divided by 6 to obtain an average value Δx3 _av of the deviation amounts in the X direction of the third register mark. An average value Δx3 _av ((Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) of the direction deviation amount is written in the memory M7 (step S357).

The absolute value of the average value Δx3 _av of the third register mark in the X direction is obtained from the average value Δx3 _{av of} the third register mark in the X direction obtained in step S357 (step S358), and the memory M63. from loading the allowable value β in the X-direction displacement amount of the third register mark (step S359), the absolute value of the average value .DELTA.x3 _av in the X direction of the displacement amount of the third register mark deviation in X direction of the third register mark It is confirmed whether or not the amount exceeds the allowable value β (step S360).

Here, if the absolute value of the average value Δx3 _av of the third register mark shift amount in the X direction exceeds the allowable value β of the shift amount of the third register mark in the X direction (YES in step S360), the memory M33. 1 is added to the count value L in the middle to set L = 8 (FIG. 43: step S340), and the process returns to step S275 (FIG. 37).

If the absolute value of the average value Δx3 _av of the deviation amount in the X direction of the third register mark does not exceed the allowable value β of the deviation amount in the X direction of the third register mark (NO in step S360), it is written in the memory M61. The total value ΣΔx3 of the amount of deviation of the third register mark in the X direction is set to zero (step S361), and the process returns to step S275 (FIG. 37).

That is, the CPU 201 stores the memory C61 in the memory M61 only when the absolute value of the average value Δx3 _av of the third register mark shift amount in the X direction exceeds the allowable value β of the shift amount of the third register mark in the X direction. The average value Δx3 _av of the deviation amount in the X direction of the third register mark is left and used when calculating ΣΔx, which will be described later.

If the count value L is L> 7 in step S341 (FIG. 44), the CPU 201 executes the processes in steps S342 to S348. For example, when the count value L was 8, CPU 201 reads the displacement amount of the third register mark in the memory M55 Δx3 _{(7) (step} S342), the deviation amount .DELTA.x3 ₍₇ in the read third register mark ₎ and written in the memory M64 as the X-direction position PMX ₇ of the latest third register mark (step S343). Then, the count value K in the memory M51 is set to K = 2, and the X-direction position PM3X ₂ (Δx3 ₍₂₎ ) of the _second third register mark is read from the K = 2nd address position of the memory M59 (FIG. 85). (See (c)), the read X-direction position PM3X ₂ (Δx3 ₍₂₎ ) of the _second third register mark is overwritten to the K-1 = 1st address position (step S345, FIG. 85 (d)). reference).

Then, 1 is added to the count value K in the memory M51 to set K = 3 (step S346), and the processes in steps S345 to S347 are repeated until the count value K becomes K = 7 in step S347. As a result, as shown in FIG. 85 (d), the X direction positions PM3X _{2 to} PM3X ₆ of the third register mark in the memory M59 are shifted laterally and written to the first to fifth address positions.

When the count value K becomes K = 7 (YES in step S347), the CPU 201 sets the latest X-direction position PMX ₇ (Δx3 ₍₇₎ ) of the third register mark written in the memory M64 to the sixth in the memory M59. (Refer to step S348, FIG. 85 (e)). Then, the total value ΣΔx3 of the amount of deviation in the X direction of the third register mark in the memory M61 is set to zero (FIG. 45: step S349), and the processes of steps S350 to 361 are performed in the same manner as described above.

As can be seen from the example in which the count value L is L = 8, in this embodiment, after the count value L becomes L ≧ 7, the X of the latest six third register marks average .DELTA.x3 _av in the X-direction displacement amount of the third register mark is obtained as an average of the direction of the deviation amount .DELTA.x3, average .DELTA.x3 _av in the X direction of the displacement of the third register mark that is the required third register Only when the allowable value β of the deviation amount of the mark in the X direction exceeds the allowable value β of the third register mark in the memory M61, the average value Δx3 _av of the deviation amount of the third register mark in the X direction remains valid.

The CPU 201 uses the average value Δx3 _av of the deviation amount in the X direction of the third register mark in the memory M61 that remains as valid each time the unwinding length L of the web 4 reaches the printing point arrival position PI. .

For example, when it is confirmed that the unwinding length L of the web 4 has reached the printing point arrival position PI ₇ (see FIG. 73) (FIG. 37: YES in step S283), the CPU 201 moves from the memory M47 to the second register mark. The rotation speed VPc of the plate cylinder / rubber cylinder driving motor is read (FIG. 38: Step S286), and the rotation speed VPc of the plate cylinder / rubber cylinder driving motor between the read second register marks is read. The signal is output to the drive motor driver 215 via the D / A converter 218 (step S287).

Then, reading the rotation speed VIr of the impression cylinder drive motor of the reference from the memory M2 (step S288), reads the Y-direction distance M2LY ₇ between the second register mark from the memory M44 (step S289), pressure of the read reference The time for passing through the printing point I of the printed material between the second register marks is determined as the second register mark passing time t _M2 from the rotational speed VIr of the cylinder driving motor and the Y-direction distance M2LY ₇ between the second register marks. The second register mark passing time t _M2 is written in the memory M52 (step S290).

Then, the CPU 201 reads from the memory M41 the amount of displacement M2Δx (M2Δx = Δx2 ₍₈₎ −Δx2 ₍₇₎ ) in the X direction between the second register marks (step S291), and also reads the X of the third register mark from the memory M7. The average value Δx3 _av ((Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) of the direction deviation is read (step S292), and the amount of deviation M2Δx (Δx2 _{( 8)} Add the average value Δx3 _av ((Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) of the X direction displacement of the third register mark to -Δx2 ₍₇₎ ) A total deviation amount ΣΔx is obtained and written in the memory M53 (step S293).

Then, the CPU 201 divides the obtained total displacement amount ΣΔx in the X direction by the second register mark passage time t _M2 obtained in step S290, and rotates the rotational speed of the X direction registration motor between the second register marks. VRc is obtained (step S294), and the obtained rotational speed VRc (VRc = M2Δx / t _M2 ) of the X-direction registration motor between the second register marks is supplied to the X-direction registration motor driver 220 as a D / A converter. The data is output via 222 (step S295), and the process returns to step S275 (FIG. 37).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) obtained in step S294, and the total deviation amount ΣΔx (ΣΔx = M2Δx + Δx3 _av in the X direction obtained in step S293) = The position of the plate cylinder 1 in the X direction is continuous at a moving speed VRc corresponding to (Δx2 ₍₈₎ −Δx2 ₍₇₎ ) + (Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) Begin to be adjusted.

That is, from the time when the length l unwinding of the web 4 has reached the print point reaches the position PI ₇ of the substrate # 7, in the X direction between the second register mark deviation amount _{M2Δx (Δx2 (8) -Δx2 (} 7) ) And the average value Δx3 _av ((Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) of the amount of deviation in the X direction between the third register mark and the plate cylinder 1 at a moving speed VRc. The position in the X direction starts to be continuously adjusted.

Thus, the position of the plate cylinder 1 is shifted in the X direction between the second register marks M2Δx until the unwinding length l of the web 4 reaches the printing point arrival position PI ₇ of the next substrate # 7. (Δx2 ₍₈₎ −Δx2 ₍₇₎ ) and the average value Δx3 _av ((Δx3 ₍₁₎ +... + Δx3 ₍₆₎ ) / 6) of the deviation amount in the X direction between the third register marks The total displacement amount ΣΔx is moved little by little in the X direction, taking into account not only the positional displacement of the substrate # 7 to the FF camera, but also the positional displacement that occurs between the FF camera and the FB camera of the substrate # 7. The horizontal position of the plate mounted on the plate cylinder 1 and the horizontal position of the substrate # 7 can be accurately matched.

  Further, printing of the printing material # 7 is started in a state where the position of the plate mounted on the plate cylinder 1 in the left-right direction and the position of the printing material # 7 in the left-right direction are accurately matched, and printing of the printing material # 7 is started. Among them, since the position of the plate cylinder 1 is continuously moved in the X direction (left and right direction) at the moving speed VRc, not only the positional deviation of the printed material # 7 to the FF camera but also the FF of the printed material # 7. In consideration of the positional deviation that occurs between the camera and the FB camera, the positional deviation that occurs on the substrate # 7 due to the meandering of the web 4 being conveyed is also corrected.

  In the present embodiment, first, the position of the second register mark RM2 is confirmed by the FF camera 305. Then, the horizontal component of the first second register mark RM2 is stored as coordinates in the camera, compared with the horizontal component of the second second register mark RM2, and the first and second ( 1 → 2) and how much the position of the second register mark RM2 moves in the left-right direction is calculated. Similarly, the horizontal shift amount between the second register marks RM2 is calculated as the second and third (2 → 3), the third and fourth (3 → 4), and so on. To do. Based on this result, the position of the plate cylinder 1 is set to the left and right in accordance with each timing (1 → 2, 2 → 3, 3 → 4,...) At which ink is transferred from the plate cylinder 1 to the rubber cylinder 2. Move by the calculated amount of deviation. As a result, the positional relationship between the second register mark RM2 and the plate cylinder 1 is maintained. Control of the position of the plate cylinder 1 in the left-right direction after confirming the position of the second register mark RM2 with the FF camera 305 is referred to as registration in the left-right direction by feedforward control (FF).

  In the present embodiment, the registration result in the left-right direction by the feedforward control is confirmed by the FB camera 306 after printing, and the amount of deviation in the left-right direction between the second register mark RM2 and the third register mark RM3 is obtained. Since the obtained shift amount is theoretically constant by the registration in the left-right direction by the feedforward control, the shift in the left-right direction is adjusted by shifting the shift amount. Actually, the amount of deviation is not constant because there is expansion and contraction in the left-right direction. For this reason, an average value of the deviation amounts is obtained, and when the average value of the deviation amounts exceeds a set threshold value, adjustment is performed by a shift operation. Control of the position of the plate cylinder 1 in the left-right direction after confirming the position of the third register mark RM3 with the FB camera 306 is referred to as left-right registration by feedback control (FB).

  As can be seen from the above description, according to the present embodiment, the WG camera 304 images the area including the first register mark RM1 of the printing object, and the FF camera 305 sets the second register mark RM2 of the printing object.
