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 printing in which the electronic circuit described above is printed on a base material, the base material is an easily stretchable member such as a film, etc., and since the base material is stretched and dried once by heat, the fiducial mark is highly accurate. When trying to detect, a plurality of expensive high-definition cameras must be provided to detect a wide range, and the equipment cost becomes expensive. In addition, there is a problem that the amount of data to be processed becomes enormous, an expensive computer having high-speed processing capability has to be used, and equipment costs are increased.

  The present invention has been made to solve such problems. The object of the present invention is to provide a circuit printed at the first time and a circuit printed at the second time without providing a plurality of expensive high-definition cameras. It is an object of the present invention to provide an electronic circuit printing method and apparatus capable of accurately aligning a position with a circuit.

  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 material to be printed at a contact point between a printing cylinder and a counter cylinder, the first reference mark and the first reference mark are printed on the printed material in a preprocessing step. A reference mark adding step for adding a small second reference mark, and a first image pickup means provided in the middle of the conveyance path of the printed material to the contact point between the printing cylinder and the counter cylinder. A first reference mark area imaging step for imaging an area including one reference mark, and a first reference mark position for detecting the position of the first reference mark from the image of the printed material imaged in the first reference mark area imaging step Detection process, printing cylinder and counter cylinder The second imaging means having an imaging range narrower than the first imaging means provided at a position closer to the contact point than the first imaging means in the middle of the conveyance path of the printed matter to the opposite contact point of the print object A second reference mark area imaging step for imaging an area including the second reference mark, and a second reference mark area imaging step in accordance with the position of the first reference mark detected in the first reference mark position detection step. And a timing calculation step for obtaining a timing at which the printing material is imaged by the imaging means.

  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 and the second reference mark smaller than the first reference mark are added to the printed material in the pre-processing step before the second circuit printing.

  In the present invention, the substrate to which the first reference mark and the second reference mark are added is conveyed to a contact point between the printing cylinder and the counter cylinder. During the conveyance of the printed material to the contact point between the printing cylinder and the counter cylinder, the first imaging means provided in the middle of the conveyance path to the contact point between the printing cylinder and the counter cylinder makes the first of the printed material. An area including the reference mark is imaged. In this case, the first fiducial mark is larger than the second fiducial mark, and a wide range of the printed material is imaged so as to include the first fiducial mark. Then, the position of the first reference mark is detected from the image of the printed material imaged by the first imaging means, and the printed material is detected by the second imaging means according to the detected position of the first reference mark. Find the timing for imaging. That is, if the position of the first reference mark is deviated from the reference image pickup position, the timing at which the printing material is imaged by the second image pickup unit is shifted according to the amount of the shift.

  The second image pickup means is provided at a position closer to the contact point than the first image pickup means in the middle of the conveyance path of the printed material to the contact point between the printing cylinder and the counter cylinder, and from the first image pickup means. Even a narrow range is imaged. In the present invention, the timing at which the second imaging unit images the printing object is adjusted according to the position of the first reference mark detected from the image of the printing object imaged by the first imaging unit. Even if the imaging range of the second imaging unit is narrow, it is possible to reliably capture an area including the second reference mark of the printed material.

  Thus, in the present invention, the first imaging means (low-resolution camera) with a wide imaging range is used to image a wide range of the printing object (first circuit), and the approximate position of the relatively large first reference mark is determined. Detect and detect a narrow range of the printed material (first circuit) with the second imaging means (high resolution camera) having a narrow imaging range according to the detected position of the detected first reference mark. The position of the second reference mark is detected, and the electronic circuit (second circuit) is accurately printed on each substrate (first circuit) in accordance with the detected position of the second reference mark. It is possible to make it happen.

  In the present invention, for example, if the rotational phase of the printing cylinder is adjusted in accordance with the position of the second reference mark detected from the image of the printing material imaged by the second imaging means, the printing material (first time The position of the electronic circuit (second circuit) printed on the circuit) can be shifted so that accurate alignment (registration) can be performed.

  In this case, from the adjustment of the rotation phase of the printing cylinder according to the position of the second reference mark detected from the image of the printing object imaged by the second imaging means, and from the image of the printing object imaged by the first imaging means You may make it combine with adjustment of the rotation phase of the printing cylinder according to the position of the detected 1st reference mark.

  That is, the adjustment of the rotation phase of the printing cylinder according to the position of the second reference mark detected from the image of the printing material imaged by the second imaging means is the first registration, and the image is taken by the first imaging means. The adjustment of the rotation phase of the printing cylinder according to the position of the first reference mark detected from the image of the printing material is the second registration, and the first registration and the second registration are combined. Good.

  When combining the first registration and the second registration, for example, after the position of the first reference mark is detected from the image of the printing object imaged by the first imaging means, the first registration mark is at the latest. The position of the first reference mark detected from the image of the printing object imaged by the first image pickup means until the image pickup by the second image pickup means of the printing object from which the position of the reference mark is detected is performed. The rotation phase of the printing cylinder is adjusted accordingly, and the position of the second fiducial mark is detected at the latest after the position of the second fiducial mark is detected from the image of the printing material imaged by the second imaging means. The printing cylinder corresponding to the position of the second reference mark detected from the image of the printing material imaged by the second imaging means until the printed material reaches the contact point between the printing cylinder and the counter cylinder Adjust the rotation phase of the .

  As a result, the first imaging unit is detected during the period from when the position of the first reference mark is detected to when the second imaging unit captures an image of the substrate on which the position of the first reference mark is detected. The rotational phase of the printing cylinder is adjusted (the initial coarse rotational phase is adjusted) according to the approximate position of the first reference mark detected from the image of the substrate imaged in step 1, and the second reference mark The image of the printing object imaged by the second imaging means from when the position was detected until the printing material for which the position of the second fiducial mark was detected reached the contact point between the printing cylinder and the counter cylinder. The rotational phase of the printing cylinder is adjusted according to the position of the second fiducial mark detected from (the initial strict rotational phase is adjusted), and the initial rotational phase of the printing cylinder is adjusted smoothly. It will be a thing.

  According to the present invention, the first reference mark and the second reference mark smaller than the first reference mark are added to the substrate to be printed in the pretreatment process, and the counter contact between the printing cylinder and the counter cylinder is achieved. The first image pickup means is provided in the middle of the conveyance path of the printing material, and is closer to the contact point than the first imaging means in the middle of the conveyance path of the printing material to the contact point of the printing cylinder and the counter cylinder. A second imaging unit having an imaging range narrower than that of the first imaging unit is provided so that the first imaging unit captures a wide area including the first reference mark of the printing object, and the second imaging unit covers the image. A narrow region including the second fiducial mark of the printed material is imaged, and the position of the first fiducial mark is detected from the image of the printed material imaged by the first imaging means. The second imaging unit captures an image of the printing object according to the position of the reference mark. Since the timing is obtained, the first imaging means (low-resolution camera) having a wide imaging range captures an image of a wide range of the printing object (first circuit) and the approximate position of the relatively large first reference mark. The second imaging means (high resolution camera) having a narrow imaging range in accordance with the detected position of the first reference mark is used to image a narrow range of the printed material (first circuit) and By detecting the position of the second reference mark, the electronic circuit (second circuit) can be accurately printed on each substrate (first circuit) without providing a plurality of expensive high-definition cameras. It is possible to do so.

[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. 11: 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).

[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. 12: step S108), and based on the read count value of the impression cylinder rotation phase detection counter 210, the current rotation phase ψ _{R of the} impression cylinder. Is calculated (step S109). Then, the reference imaging position PWGr of the WG camera is read from the memory M8 (step S110), and it is confirmed whether or not the current rotational phase ψ _R of the impression cylinder is at the reference imaging position PWGr of the WG camera (step S111).

When the CPU 201 repeats the processing operations in steps S108 to S111 and confirms that the current rotation phase ψ _R of the impression cylinder has reached the reference imaging position PWGr of the WG camera (YES in step S111), the rotation count of the printing press is counted. The enable signal and the reset signal are output to the counter 213 (step S112), and the output of the reset signal to the counter 213 for counting the number of rotations of the printing press is stopped (step S113). As a result, the counter 213 for counting the number of rotations of the printing press starts counting from zero.

  The CPU 201 transmits the imaging command of the WG camera to the deviation amount detection device 300 simultaneously with the start of counting from zero of the counter 213 for counting the number of rotations of the printing press (step S114), and sends a response from the deviation amount detection device 300. Wait (steps S115 and S117 (FIG. 13)).

  If a signal without the first register mark is transmitted from the deviation amount detection device 300 (YES in step S115), the CPU 201 transmits a signal reception completion signal without the first register mark to the deviation amount detection device 300. (Step S116), the process returns to Step S108.

  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 S117), 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 M9 and M10 (step S118).

[Image of printed material by WG camera (detection of shift amount of first register mark by shift amount detection device)]
CPU301 of deviation | shift amount detection apparatus 300 will output an imaging command to WG camera 304, if the imaging command of a WG camera is sent from the drive control apparatus 200 (FIG. 26: YES of step S301) (step S302). 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 rotation phase ψ _R of the impression cylinder is located at the reference imaging position PWGr of the WG camera, the WG camera 304 The image of the printing material on the web 4 is conveyed.

  When image data is sent from the WG camera 304 (YES in step S303), the CPU 301 sets the count value Y in the memory M41 to 1 (step S304), and sets the count value X in the memory M42 to 1 (step S305). ), The imaging data of the pixel position specified by the count values X and Y from the WG camera 304 is written in the address position (X, Y) of the memory M43 (step S306).

  Then, the CPU 301 adds 1 to the count value X in the memory M42 (FIG. 27: Step S307), reads the number of pixels a in the left-right direction of the WG camera in the memory M44 (Step S308), and counts in Step S309. The processing operations in steps S306 to S309 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 S309), 1 is added to the count value Y in the memory M41 (step S310), and the top and bottom of the WG camera in the memory M45. The number of pixels b in the direction is read (step S311), and the processing operations in steps S305 to S312 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the WG camera in step S312.

  Thereby, the imaging data of the a × b pixel from the WG camera 304 is stored in the memory M43. Here, as shown in FIG. 40 (a), imaging data of a wide area including the first register mark RM1 of the first substrate # 1 is stored in the memory M43 as imaging data of a × b pixels. And

  In the memory M48, as shown in FIG. 40B, the c × d pixel data of the first register mark RM1 is stored as data for pattern matching. 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 M41 to 1 (step S313), sets the count value X in the memory M42 to 1 (step S314), and sets the count value N in the memory M46 to 1 (FIG. 28: FIG. 28). In step S315), the count value M in the memory M47 is set to 1 (step S316).

  Then, the imaging pixel data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M43 is read (step S317), and the first register mark at the address position (M, N) in the memory M48 is read. The pixel data is read (step S318). The read pixel data of the WG camera at the address position (X + M-1, Y + N-1) in the read memory M43 and the (M, N) address position in the memory M48. It is confirmed whether or not the pixel data of one register mark matches (see step S319, FIGS. 40A and 40B).

  Here, the image data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M43 and the pixel data of the first register mark at the address position (M, N) in the memory M48 are identical. If not (NO in step S319), 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 M42 (FIG. 29: step S320). ) Read the horizontal pixel number a of the WG camera in the memory M44 and the horizontal pixel number c of the first register mark in the memory M49 (step). S321, S322), at step S323 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S315～S323.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S323), it means that the left and right ends of the image data of the WG camera 304 have been exceeded, so the CPU 301 stores in the memory M41. 1 is added to the count value Y (step S324), and the vertical pixel count b of the WG camera in the memory M45 and the vertical pixel count d of the first register mark in the memory M50 are read (steps S325 and S326). ), The processing operations of steps S314 to S327 are repeated until the count value Y exceeds “b−d + 1” in step S327.

  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 M43 and the pixel data of the first register mark at the address position (M, N) in the memory M48 Are confirmed (FIG. 28: YES in step S319), the CPU 301 adds 1 to the count value M in the memory M47 (step S330), and the left and right of the first register mark are read from the memory M49. The number of pixels c in the direction is read (step S331), and the processing operations of steps S317 to S332 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 S332 (FIG. 30).

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S332), the CPU 301 adds 1 to the count value N in the memory M46 (step S333), and the first value from the memory M50 is the first. The pixel number d in the vertical direction of the register mark is read (step S334), and the processing operations in steps S316 to S335 are repeated until the count value N exceeds the pixel number d in the vertical direction of the first register mark in step S335.

  In this manner, the CPU 301 performs pattern matching of the pixel data of the c × d first register mark in the memory M48 with respect to the imaging data of the a × b pixel in the memory M43, and the count value N is the first. When the number of pixels d in the vertical direction of the register mark is exceeded (YES in step S335), (X + c-1, Y + d-1) from the (X, Y) address of the imaging data of the a × b pixel in the memory M43. It is determined that the pixel data of the c × d first register mark in the memory M48 is included in the range up to the address. 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 S327 (FIG. 29) (YES in step S327), 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 indicating no first register mark to the drive control device 200 (step S328). Then, upon receiving the signal reception completion signal without the first register mark from the drive control device 200 (YES in step S329), the process returns to step S301 (FIG. 26), and the imaging command for the next WG camera from the drive control device 200 is received. Prepare for.

  When the CPU 301 determines that the first register mark is included in the image captured by the WG camera 304 (FIG. 30: YES in step S335), the CPU 301 reads the count value X in the memory M42 at that time (step S336). 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 M51 (step S337). 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 M52 (step S338), 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 the first register mark displacement amount Δx1 in the X direction (see FIG. 40C), and the obtained first register mark displacement amount Δx1 in the X direction is written to the address position in the X direction of the memory M53. (Step S339).

  Further, the CPU 301 reads the count value Y in the memory M41 at that time (FIG. 31: step S340), calculates the measurement position in the Y direction of the first register mark from the read count value Y, and Y in the memory M51. Write to the address position in the direction (step S341). 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 M52 (step S342), 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 Y-direction shift amount Δy1 of the first register mark (see FIG. 40C), and the Y-direction shift amount Δy1 of the first register mark thus obtained is written in the Y-direction address position of the memory M53. (Step S343).

  Then, 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 M53 (step S344). Then, upon receipt of the first register mark shift amount reception completion signal from the drive control device 200 (YES in step S345), the first register mark shift amount Δx1 in the X direction to the drive control device 200 and the shift in the Y direction. The transmission of the amount Δy1 is stopped (step S346), and the process returns to step S301 (FIG. 26) 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. 13: YES in step S117), 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 M9 and M10 (step S118), 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 S119).

  Then, the CPU 201 reads the reference imaging position PWGr of the WG camera from the memory M8 (step S120), reads the displacement amount Δy1 of the first register mark in the Y direction from the memory M10 (step S121), and reads the reference imaging position PWGr of the WG camera. Then, the current original image pickup position (image pickup position of the WG camera) PWG 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 of the WG camera is written in the memory M11 (step S122). ).

  Note that the current original imaging position PWG 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 of the FF camera thereafter This is a reference for imaging timing.

  Further, the CPU 201 reads the WG camera-FF camera distance L1 from the memory M12 (step S123), and based on the WG camera imaging position PWG and the WG camera-FF camera distance L1 obtained in step S122, the FF camera imaging position PFF. And the obtained imaging position PFF of the FF camera is written in the memory M13 (step S124).

  FIG. 39 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 displacement Δy1 (the WG camera's current original imaging). (Position) PWG, the WG camera imaging position PWG, and the WG camera-FF camera imaging position PFF obtained from the WG camera imaging position PFF.

  In FIG. 39, PFFr is the reference image pickup position of the FF camera, PIr is the reference print point arrival position of the first print object, and the reference image pickup position PWGr of the WG camera and the reference image pickup position PFFr of the FF camera are the print object. The reference image pickup position PFFr of the FF camera and the reference print point arrival position PIr of the substrate to be printed are one sheet. More than this (in this example, ≈ 1.16 sheets). Note that PI is the print point arrival position of the first substrate, and the print point arrival position PI of the first substrate will be described later.

  After writing the imaging position PFF of the FF camera in the memory M13 (FIG. 13: step S124), the CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (FIG. 14: step S125). The count value is read from the phase detection counter 210 (step S126), and the current unwinding length l of the web 4 is determined from the count value of the counter 213 for counting the number of rotations of the printing press and the count value of the counter 210 for detecting the impression cylinder rotation phase. Is obtained (step S127). Then, the imaging position PFF of the FF camera is read from the memory M13 (step S128), and it is confirmed whether or not the unwinding length l of the current web 4 has reached the imaging position PFF of the FF camera (step S129).

[Adjustment of initial rough rotation phase of plate cylinder and rubber cylinder]
The CPU 201 repeats the processing operations of steps S130 (FIG. 15) to S149 (FIG. 17) until it is confirmed in step S129 that the web 4 has an unwinding length l of FF camera that has reached the imaging position PFF. In the processing of steps S130 to S149, 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. 15: step S130), 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 S131). Then, the amount of displacement Δy1 in the Y direction of the first register mark is read from the memory M10 (step S132), 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 S133).

Then, the CPU 201 obtains the plate cylinder / rubber cylinder rotation phase φm that should be based on the corrected current cylinder rotation phase ψ _R ′ (step S134), and counts from the plate cylinder / rubber cylinder rotation phase detection counter 217. Is read (step S135), 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 S136). 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 S134 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. Then, the obtained rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is written in the memory M20 (step S137).

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 S137 (FIG. 16: Step S138) Then, the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder is read from the memory M22 (step S139), 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 rotational phase difference is equal to or smaller than a first allowable value α1 (step S140).

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 first allowable value α1 of the rotational phase difference of the plate cylinder / rubber cylinder (NO in step S140), 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 M23 (step S141), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M20 (step S141). S142), a correction value ΔV of the rotational speed is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder using the correction value conversion table of the current rotation phase difference / rotation speed of the plate cylinder / rubber cylinder (step S143). ).

  The CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S144), 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 S145), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor is determined as the plate cylinder / rubber cylinder. It outputs to the drive motor driver 215 via the D / A converter 218 (step S146), returns to step S125 (FIG. 14), and repeats 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. 16: YES in step S140), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 17: Step S147), 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 S148), 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 S148). S149).

The CPU 201 repeats the processing operations of steps S130 to S149 until the unwinding length l of the web 4 reaches the imaging position PFF of the FF camera. In step S140, the current rotational phase difference Δφ _R of the plate cylinder and the rubber cylinder is repeated. 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 S147 to S149. 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 CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFF of the FF camera (FIG. 14: YES in step S129), the CPU 201 reads the value written in the memory M4 (step S150). It is confirmed whether or not the value written in the memory M4 is “1” (step S151). If the value written in the memory M4 is not “1” (NO in step S151), the process returns to step S106 (FIG. 11), but if the value written in the memory M4 is “1”. (YES in step S151), it is determined that the phase deviation correction by the first register mark has been completed.

  In this manner, in the present embodiment, after the position of the first register mark RM1 is detected from the image of the first substrate # 1 imaged by the WG camera 304 (point t1 shown in FIG. 39), at the latest Until the unwinding length l of the web 4 reaches the imaging position PFF of the FF camera (point t2 shown in FIG. 39), that is, an area including the second register mark RM2 of the first substrate # 1 by the FF camera 305. The initial rough rotation phase of the plate cylinder / rubber cylinder is adjusted in accordance with the position of the first register mark RM1 until the first imaging is performed. In the present invention, the initial coarse rotation phase adjustment of the plate cylinder / rubber cylinder is named second registration.

[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. 14: YES in step S151), the CPU 201 transmits an imaging command of the FF camera to the deviation amount detection device 300 (FIG. 18). Step S152), waiting for transmission of the deviation amount Δx2 in the X direction and the deviation amount Δy2 in the Y direction of the second register mark from the deviation amount detection device 300 (Step S153).

[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. 32: YES in step S348), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the FF camera 305 (step S349). 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 of the FF camera. An image of the printing material on the coming web 4 is taken.

  When image data is sent from the FF camera 305 (YES in step S350), the CPU 301 sets the count value Y in the memory M41 to 1 (step S351), and sets the count value X in the memory M42 to 1 (step S352). ), The imaging data at the pixel position specified by the count values X and Y from the FF camera 305 is written to the address position (X, Y) of the memory M54 (step S353).

  Then, the CPU 301 adds 1 to the count value X in the memory M42 (FIG. 33: Step S354), reads the number of pixels e in the horizontal direction of the FF camera in the memory M55 (Step S355), and counts in Step S356. The processing operations in steps S353 to S356 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 S356), 1 is added to the count value Y in the memory M41 (step S357), and the top and bottom of the FF camera in the memory M56 The number of pixels f in the direction is read (step S358), and the processing operations in steps S352 to S359 are repeated until the count value Y exceeds the number of pixels f in the vertical direction of the FF camera in step S359.

  As a result, the imaging data of the e × f pixels from the FF camera 305 is stored in the memory M54. Here, as shown in FIG. 41A, it is assumed that the imaging data of the area including the second register mark RM2 of the substrate # 1 is stored in the memory M54 as the imaging data of the pixel of e × f.

  The memory M57 stores g × h pixel data of the second register mark as pattern matching data, as shown in FIG. 41 (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.

  Next, the CPU 301 sets the count value Y in the memory M41 to 1 (FIG. 34: step S360), sets the count value X in the memory M42 to 1 (step S361), and sets the count value N in the memory M46 to 1 ( In step S362, the count value M in the memory M47 is set to 1 (step S363).

  Then, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M54 is read (step S364), and the second register mark at the address position (M, N) in the memory M57 is read. The pixel data is read (step S365), and the read image data of the FF camera at the address position (X + M-1, Y + N-1) in the memory M54 and the (M, N) address position in the memory M57 are read. It is confirmed whether or not the pixel data of the two register marks match (see step S366, FIGS. 41A and 41B).

  Here, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M54 and the pixel data of the second register mark at the address position (M, N) in the memory M57 are identical. If not (NO in step S366), 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, since there is no second register mark in the range starting from the address (X, Y), the CPU 301 adds 1 to the count value X in the memory M42 (FIG. 35: step S367). ) Read the number of pixels e in the left-right direction of the FF camera in the memory M55 and the number of pixels g in the left-right direction of the second register mark in the memory M58 (step) S368, S369), the processing operation of steps S362 to S370 is repeated until the count value X exceeds “eg + 1” in step S370.

  During this processing operation, if the count value X exceeds “eg + 1” (YES in step S370), 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 in the memory M41. 1 is added to the count value Y (step S371), and the vertical pixel count f of the FF camera in the memory M56 and the vertical pixel count h of the second register mark in the memory M59 are read (steps S372 and S373). ), The processing operations of steps S361 to S374 are repeated until the count value Y exceeds “f−h + 1” in step S374.

  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 M54 and the pixel data of the second register mark at the address position (M, N) in the memory M57 Are confirmed (FIG. 34: YES in step S366), the CPU 301 adds 1 to the count value M in the memory M47 (FIG. 36: step S376), and the second register from the memory M58. The number of pixels g in the left-right direction of the mark is read (step S377), and the processing operations of steps S364 to S378 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 S378.

  When the count value M exceeds the number of pixels g in the left-right direction of the second register mark (YES in step S378), 1 is added to the count value N in the memory M46 (step S379), and the second register mark is registered from the memory M59. The number h of pixels in the vertical direction is read (step S380), and the processing operations in steps S363 to S381 are repeated until the count value N exceeds the number h of pixels in the vertical direction of the second register mark in step S381.

  In this manner, the CPU 301 performs pattern matching of the pixel data of the g × h second register mark in the memory M57 with respect to the imaging data of the e × f pixel in the memory M54, and the count value N is the second value. When the number h of pixels in the vertical direction of the register mark is exceeded (YES in step S381), (X + g-1, Y + h-1) from the (X, Y) address of the imaging data of the e × f pixel in the memory M54. It is determined that the pixel data of the g × h second register mark in the memory M57 is included in the range up to the address. 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 S374 (FIG. 35) (YES in step S374), 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 S375).

  When the CPU 301 determines that the second register mark is included in the image captured by the FF camera 305 (YES in step S381), the CPU 301 reads the count value X in the memory M42 at that time (step S382) 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 M60 (FIG. 37: step S383). Then, the X-direction reference position of the second register mark is read from the X-direction address position of the memory M61 (step S384), 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 an X-direction deviation amount Δx2 of the second register mark (see FIG. 41C), and the obtained X-direction deviation amount Δx2 of the second register mark is written in the X-direction address position of the memory M62. (Step S385).

  Further, the CPU 301 reads the count value Y in the memory M41 at that time (step S386), calculates the measurement position in the Y direction of the second register mark from the read count value Y, and the Y direction address in the memory M60. The position is written (step S387). 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 M61 (FIG. 38: Step S388), and the Y register in the Y direction is measured from the measured position in the Y direction of the second register mark. The reference position is subtracted to determine the amount of displacement Δy2 in the Y direction of the second register mark (see FIG. 41C), and the amount of displacement Δy2 in the Y direction of the second register mark thus obtained is used as the address in the Y direction of the memory M62. The position is written (step S389).

  Then, the CPU 301 transmits the obtained displacement amount Δx2 in the X direction and displacement amount Δy2 in the Y direction of the second register mark to the drive control device 200 (step S390). Then, upon receipt of the second register mark shift amount reception completion signal from the drive control device 200 (YES in step S391), the second register mark shift amount Δx2 in the X direction and the Y direction shift to the drive control device 200. The transmission of the amount Δy2 is stopped (step S392), and the process returns to step S301 (FIG. 26) to prepare for the next WG camera imaging command from the drive control device 200.

[Detection of position of second register mark in drive controller]
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. 18: YES in step S153), The received X-direction displacement amount Δx2 and Y-direction displacement amount Δy2 of the received second register mark are written in the memories M26 and M27 (step S154), and the displacement amount detection device 300 transmits a displacement amount reception completion signal of the second register mark. (Step S155).

  Then, the CPU 201 reads the imaging position PFF of the FF camera from the memory M13 (step S156), obtains the position PM2 of the second register mark from the imaging position PFF of the FF camera and the amount of deviation Δy2 of the second register mark in the Y direction, The obtained position PM2 of the second register mark is written in the memory M28 (step S157).

  Further, the CPU 201 reads the FF camera-printing point distance L2 from the memory M29 (step S158), and the first substrate # from the second register mark position PM2 and the FF camera-printing point distance L2 obtained in step S157. The printing point arrival position PI of 1 is obtained, and the obtained printing point arrival position PI of the first substrate # 1 is written in the memory M30 (step S159).

  Next, the CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (FIG. 19: step S160), and also reads the count value from the counter 210 for detecting the pressure drum rotation phase (step S161). From the count value of the counter 213 for counting the number of rotations and the count value of the counter 210 for detecting the impression cylinder rotation phase, the current unwinding length l of the web 4 is obtained (step S162). Then, the printing point arrival position PI of the first substrate # 1 is read from the memory M30 (step S163), and the unwinding length l of the current web 4 reaches the printing point arrival position PI of the first substrate # 1. Whether or not (step S164).

[Initial strict rotation phase adjustment of plate cylinder and rubber cylinder]
The CPU 201 performs steps S165 (FIG. 20) to S184 (FIG. 22) until it is confirmed in step 164 that the first printing material # 1 having the unwinding length l of the web 4 has reached the printing point arrival position PI. Repeat the processing operation. In the processing of steps S165 to S184, the initial strict rotational phase adjustment of the plate cylinder / rubber cylinder is performed. 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. 20: step S165), 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 S166). Then, the amount of displacement Δy2 of the second register mark in the Y direction is read from the memory M27 (step S167), 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 S168).

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 S169), and the count value from the plate cylinder / rubber cylinder rotation phase detection counter 217. (Step S170), and the current rotation phase φ _R of the plate cylinder / rubber cylinder is obtained from the count value of the read plate cylinder / rubber cylinder rotation phase detection counter 217 (step S171). 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 S169 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. Then, the obtained rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is written in the memory M20 (FIG. 21: step S172).

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 S172 (step S173), the memory M31 Then, the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder is read (step S174), and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is the rotational phase difference of the plate cylinder / rubber cylinder. It is confirmed whether or not it is equal to or smaller than the second allowable value α2 (step S175). In the present embodiment, the second allowable value α2 is determined as a value (α2 <α1) smaller than the first allowable value α1 used in the initial coarse rotation phase adjustment of the plate cylinder / rubber cylinder. .

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 S175), 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 M23 (step S176), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M20 (step S176). S177), the correction value ΔV of the rotational speed is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder using the current rotational phase difference-rotation speed correction value conversion table of the plate cylinder / rubber cylinder (step S178). ).

  Then, the CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S179), 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 S180), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor is determined as the plate cylinder / rubber cylinder. It outputs to the drive motor driver 215 via the D / A converter 218 (step S181), and returns to step S160 (FIG. 19) 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. 21: YES in step S175), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 22: Step S182), 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 S183), 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 S183). S184).

The CPU 201 repeats the processing operations in steps S160 to S184 until the unwinding length l of the web 4 reaches the printing point arrival position PI of the first substrate # 1, but in step S175, the current state of the plate cylinder and the rubber cylinder is repeated. If the absolute value of the rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is not equal to or smaller than the second allowable value α 2 of the rotational phase difference between the plate cylinder and the rubber cylinder, the process does not proceed to steps S182 to S184. 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.

  When the CPU 201 confirms that the unwinding length l of the web 4 has reached the printing point arrival position PI of the first substrate # 1 (FIG. 19: YES in step S164), the CPU 201 sets the value written in the memory M5. Reading (step S185), it is confirmed whether or not the value written in the memory M5 is “1” (step S186). If the value written in the memory M5 is not “1” (NO in step S186), the process returns to step S106 (FIG. 11), but if the value written in the memory M5 is “1”. (YES in step S186), it is determined that the phase deviation correction 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 captured by the FF camera 305 (point t2 shown in FIG. 39), at the latest Until the unwinding length l of the web 4 reaches the printing point arrival position PI of the first substrate # 1 (point t3 shown in FIG. 39), the plate cylinder / rubber according to the position of the second register mark RM2. The initial rotational phase of the cylinder is strictly adjusted. In the present invention, the initial precise rotation phase adjustment of the plate cylinder / rubber cylinder is termed the first registration.

[Synchronization of rotation phase of impression cylinder and printing cylinder / rubber cylinder during printing]
When the CPU 201 determines that the correction of the phase deviation by the second register mark is complete (FIG. 19: YES in step S186), the CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 23: step). S187), the current rotation phase ψ _R of the impression cylinder is obtained from the read count value of the impression cylinder rotation phase detection counter 210 (step S188).

Then, the plate cylinder / rubber cylinder rotation phase φm should be obtained from the determined current rotation phase ψ _R of the impression cylinder (step S189), and the count value is read from the plate cylinder / rubber cylinder rotation phase detection counter 217 ( In step S190, the current rotation phase φ _R of the plate cylinder / rubber cylinder is obtained from the count value of the read plate cylinder / rubber cylinder rotation phase detection counter 217 (step S191).

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 S189 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 M20 (step S192).

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 S192 (FIG. 24: step S193), The second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder is read from the memory M31 (step S194), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is the rotation of the plate cylinder and the rubber cylinder. It is checked whether or not the phase difference is equal to or smaller than the second allowable value α2 (step S195).

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 S195), 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 M23 (FIG. 25: Step S196), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M20. Reading (step S197), the correction value ΔV of the rotation speed is obtained from the current rotation phase difference Δφ _{R of} the plate cylinder / rubber cylinder using the correction value conversion table of the current rotation phase difference / rotation speed of the plate cylinder / rubber cylinder. (Step S198).

  Then, the rotational speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (step S199), and the rotational speed correction value ΔV is added to the rotational speed VPr of the standard printing cylinder / rubber cylinder driving motor. Then, the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder driving motor is obtained (step S200), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder driving motor is determined as the plate cylinder / rubber cylinder driving motor. The data is output to the driver 215 via the D / A converter 218 (step S201), and the process returns to step S187 (FIG. 23).

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 between the plate cylinder and the rubber cylinder becomes equal to or less than the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder (FIG. 24: YES in step S195), the CPU 201 The rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor is read from M3 (step S202), and the reference rotation speed VPr of the read plate cylinder / rubber cylinder driving motor is read as the plate cylinder / rubber cylinder driving motor driver. The data is output to 215 via the D / A converter 218 (step S203), and the process returns to step S187 (FIG. 23).

In this way, in the present embodiment, the rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted even during printing, and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is determined by the plate. The rotational phase difference between the cylinder and the rubber cylinder is always adjusted to be equal to or less than the second allowable value α2, and the rotational phases of the impression cylinder and the plate cylinder / rubber cylinder during printing are synchronized.

  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 # 1, and the FF camera 305 performs the second printing of the printing object # 1. The region including the register mark RM2 is imaged, the position of the first register mark RM1 is detected from the image of the first substrate # 1 imaged by the WG camera 304, and the detected first register mark RM1 is detected.

Thus, the electronic circuit (second circuit) can be accurately printed on each substrate (first circuit) without providing a plurality of expensive high-definition cameras.

  Further, according to the present embodiment, from the time when the position of the first register mark RM1 is detected until the position where the position of the first register mark RM1 is detected is captured by the FF camera 305 at the latest. In the meantime, the rotational phase of the plate cylinder / rubber cylinder is adjusted according to the approximate position of the first register mark RM1 detected from the image of the first substrate # 1 captured by the WG camera 304 (the initial coarse rotational phase). The first printed material # 1 from which the position of the second register mark RM2 has been detected is the contact point between the rubber cylinder 2 and the impression cylinder 3 at the latest after the position of the second register mark RM2 has been detected. (Printing point) Rotation of the plate cylinder / rubber cylinder according to the position of the second register mark RM2 detected from the image of the first substrate # 1 imaged by the FF camera 305 until reaching the printing point I The phase is adjusted (the initial strict rotation phase adjustment is performed), and the initial rotation phase of the plate cylinder / rubber cylinder is adjusted smoothly so that the electrons to each substrate (first circuit) are printed. The circuit (second circuit) can be printed accurately.

  In the above-described embodiment, the first register mark RM1 and the second register mark RM2 are added only to the top printed material (first printed material) # 1 of the web 4, but all the printed materials are used.
