Then, as shown in FIG. 1, the substrate 4A on which the first circuit is printed in the preprocessing step is set on the table 3, and the print preparation start switch 207 is turned on.

[Register Mark Imaging]
When the print preparation start switch 207 is turned on (YES in step S103), the CPU 201 of the flatbed printing control apparatus 200 reads the rotational speed Vc of the camera moving motor from the memory M1 (step S104), and the camera moving motor driver. A normal rotation command and the rotational speed Vc of the camera moving motor are output to 212 via the D / A converter 215 (step S105). Thereby, the camera moving motor 211 rotates forward at the rotation speed Vc, and the left camera 210L and the right camera 210R move leftward on the table 3 with the initial position shown in FIG. 1 (FIG. 2) as the origin position. Move at the same time.

While the left camera 210L and the right camera 210R are moving, the CPU 201 reads the count value of the camera position detection counter 214 (step S106), and the left camera 210L and the right camera 210R are read from the count value of the camera position detection counter 214. The current position PCM _R is calculated (step S107), the first mark position PM1 is read from the memory M4 (step S108), and the current positions PCM _R of the left camera 210L and the right camera 210R have reached the first mark position PM1. Whether or not (step S109).

When the CPU 201 confirms that the current positions PCM _R of the left camera 210L and the right camera 210R have reached the first mark position PM1 (YES in step S109), the CPU 201 outputs a stop command to the camera movement motor driver 212 ( Step S110), the movement of the left camera 210L and the right camera 210R is stopped. Then, imaging commands are output to the left camera 210L and the right camera 210R (step S111), and an area including the first register mark RM1 _L1 on the substrate 4 set in the table 3 is imaged by the left camera 210L. An area including the first register mark RM1 _R1 on the printed material 4 is imaged by the right camera 210R.

  Then, the CPU 201 sends an imaging data transmission command to the left camera 210L (FIG. 14: Step S112). When imaging data is sent from the left camera 210L in response to this transmission command (YES in Step S113), the memory The count value Y in M5 is set to 1 (step S114), the count value X in the memory M6 is set to 1 (step S115), and the imaging data from the left camera 210L at the pixel position specified by the count values X and Y is stored in the memory. Write to the address position of (X, Y) in M7 (step S116).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S117), reads the number of pixels a in the horizontal direction of the camera in the memory M8 (step S118), and in step S119, the count value X is determined by the camera. The processing operations in steps S116 to S119 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the left-right direction of the camera (YES in step S119), 1 is added to the count value Y in the memory M5 (step S120), and the vertical direction of the camera in the memory M9 is increased. The number of pixels b is read (step S121), and the processing operations of steps S115 to S122 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S122.

Thereby, the imaging data of the a × b pixel from the left camera 210L at the first mark position PM1 is stored in the memory M7. Here, as shown in FIG. 66 (a), the imaging data including the first register mark RM1 _L1 of the substrate 4A is stored in the memory M7 as imaging data of a × b pixels.

  In the memory M16, as shown in FIG. 66B, c × d pixel data of the first register mark RM1 is stored as data for pattern matching. The vertical direction of the camera is the same as the vertical direction of the printing object 4A, and the horizontal direction of the camera is the same as the horizontal direction of the printing object 4A.

  Next, the CPU 201 sends an imaging data transmission command to the right camera 210R (FIG. 15: step S123). When imaging data is sent from the right camera 210R in response to this transmission command (YES in step S124), The count value Y in the memory M5 is set to 1 (step S125), the count value X in the memory M6 is set to 1 (step S126), and the imaging data from the right camera 210R at the pixel position specified by the count values X and Y is obtained. Write to the address position (X, Y) of the memory M11 (step S127).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S128), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S129), and the count value X is set to the camera value in step S130. The processing operations in steps S127 to S130 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the horizontal direction of the camera (YES in step S130), 1 is added to the count value Y in the memory M5 (step S131), and the vertical direction of the camera in the memory M9 is increased. The number of pixels b is read (step S132), and the processing operations of steps S126 to S133 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S133.

Thereby, the imaging data of the a × b pixel from the right camera 210R at the first mark position PM1 is stored in the memory M11. Here, as shown in FIG. 67A, the imaging data including the first register mark RM1 _R1 of the substrate 4A is stored in the memory M11 as imaging data of a × b pixels.

  Next, the CPU 201 reads the rotational speed Vc of the camera moving motor from the memory M1 (FIG. 16: Step S134), and performs D / A conversion on the reverse rotation command to the camera moving motor driver 212 and the rotational speed Vc of the camera moving motor. The data is output via the device 215 (step S135). As a result, the camera moving motor 211 reverses at the rotation speed Vc, and the left camera 210L and the right camera 210R that have stopped at the first mark position PM1 in FIG. Move at the same time.

While the left camera 210L and the right camera 210R are moving, the CPU 201 reads the count value of the camera position detection counter 214 (step S136). The current position PCM _R is calculated (step S137), the second mark position PM2 is read from the memory M10 (step S138), and the current positions PCM _R of the left camera 210L and the right camera 210R have reached the second mark position PM2. Whether or not (step S139).

When confirming that the current position PCM _R of the left camera 210L and the right camera 210R has reached the second mark position PM2 (YES in step S139), the CPU 201 outputs an imaging command to the left camera 210L and the right camera 210R ( In step S140), an area including the first register mark RM1 _L2 on the printed material 4A is imaged by the left camera 210L, and an area including the first register mark RM1 _R2 on the printed material 4A is imaged by the right camera 210R.

  Then, the CPU 201 sends an imaging data transmission command to the left camera 210L (step S141). When imaging data is sent from the left camera 210L in response to this transmission command (YES in step S142), the CPU 201 stores the data in the memory M5. The count value Y is set to 1 (step S143), the count value X in the memory M6 is set to 1 (FIG. 17: step S144), and the imaging data from the left camera 210L at the pixel position specified by the count values X and Y is stored in the memory. Write to the address position (X, Y) of M12 (step S145).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S146), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S147), and the count value X is read from the camera in step S148. The processing operations in steps S145 to S148 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the left-right direction of the camera (YES in step S148), 1 is added to the count value Y in the memory M5 (step S149), and the camera in the vertical direction of the camera in the memory M9. The number of pixels b is read (step S150), and the processing operations of steps S144 to S151 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S151.

Thereby, the imaging data of the a × b pixel from the left camera 210L at the second mark position PM2 is stored in the memory M12. Here, as shown in FIG. 68A, the imaging data including the first register mark RM1 _L2 of the printing material 4A is stored in the memory M12 as imaging data of a × b pixels.

  Next, the CPU 201 sends an imaging data transmission command to the right camera 210R (step S152). When imaging data is sent from the right camera 210R in response to the transmission command (YES in step S153), the CPU 201 stores the imaging data in the memory M5. 1 is set to 1 (FIG. 18: step S154), the count value X in the memory M6 is set to 1 (step S155), and the imaging data from the right camera 210R at the pixel position specified by the count values X and Y is obtained. Write to the address position (X, Y) in the memory M13 (step S156).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S157), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S158), and the count value X is determined by the camera in step S159. The processing operations in steps S156 to S159 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the horizontal direction of the camera (YES in step S159), 1 is added to the count value Y in the memory M5 (step S160), and the vertical direction of the camera in the memory M9 is increased. The number of pixels b is read (step S161), and the processing operations of steps S155 to S162 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S162.

Thereby, the imaging data of the a × b pixel from the right camera 210R at the second mark position PM2 is stored in the memory M13. Here, as shown in FIG. 69 (a), the imaging data including the first register mark RM1 _R2 of the substrate 4A is stored in the memory M13 as imaging data of a × b pixels.

  Then, the CPU 201 continues to move the left camera 210L and the right camera 210R, and when the camera origin position detector 216 detects the return to the origin position (first position) of the left camera 210L and the right camera 210R (in step S163). YES), a stop command is sent to the camera movement motor driver 212 (step S164), and the movement of the left camera 210L and the right camera 210R is stopped.

[Detection of position of first register mark by pattern matching]
Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 19: Step S165), sets the count value X in the memory M6 to 1 (Step S166), and sets the count value N in the memory M14 to 1 ( In step S167, the count value M in the memory M15 is set to 1 (step S168).

  The pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M7 is read (step S169), and the pixel of the first register mark at the address position (M, N) in the memory M16 is read. The data is read (step S170), the pixel data of the left camera at the address position (X + M-1, Y + N-1) in the memory M7 and the pixel data at the address position (M, N) in the memory M16 are read. Is confirmed (see step S171, FIGS. 66A and 66B).

Here, the pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M7 matches the pixel data of the first register mark at the address position (M, N) in the memory M16. If not (NO in step S169), any of the imaging data at the first mark position of the left camera 210L from the address (X, Y) to the address (X + c-1, Y + d-1) at that time Since the pixel data is different from the pixel data of the first register mark, the first register mark RM1 _{L1 on} the left of the first mark position PM1 does not exist in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 20: step S172), the number of pixels a in the horizontal direction of the camera in the memory M8 and the first register mark in the memory M17 Reading a pixel number c in the horizontal direction (step S173, S174), in step S175 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S167～S175.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S175), it means that the left and right ends of the imaging data at the first mark position of the left camera 210L have been exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S176), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels d in the vertical direction of the first register mark in the memory M18. Reading (steps S177 and S178), the processing operations of steps S166 to S179 are repeated until the count value Y exceeds “b−d + 1” in step S179.

  During this processing operation, the pixel data of the left camera at the (X + M−1, Y + N−1) address position in the memory M7 and the pixel data of the first register mark at the (M, N) address position in the memory M16 are obtained. When it is confirmed that they match (FIG. 19: YES in step S171), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 21: step S181), and the first register mark is read from the memory M17. The left-right pixel number c is read (step S182), and the processing operations of steps S169 to S183 are repeated until the count value M exceeds the left-right pixel number c of the first register mark in step S183.

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S183), the CPU 201 adds 1 to the count value N in the memory M14 (step S184), and the first value from the memory M18. The number of pixels d in the vertical direction of the register mark is read (step S185), and the processing operations of steps S168 to S186 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first register mark in step S186.

In this way, the CPU 201 captures pixel data of the first register mark of c × d in the memory M16 with respect to imaging data of the pixel of a × b in the memory M7 (imaging data of the left first mark position). When the count value N exceeds the number of pixels d in the vertical direction of the first register mark (YES in step S186), the (X, Y) of the imaging data of the a × b pixel in the memory M7 It is determined that the pixel data of the c × d first register mark in the memory M16 is included in the range from the address to the address of (X + c−1, Y + d−1). That is, it is determined that the first register mark RM1 (RM1 _L1 ) is included in the image at the first mark position PM1 captured by the left camera 210L.

If the count value Y exceeds “b−d + 1” in step S179 (YES in step S179), it means that the top and bottom ends of the imaging data at the first mark position of the left camera 210L have been exceeded. Thus, the CPU 201 determines that the first register mark RM1 (RM1 _L1 ) is not included in the image at the first mark position PM1 captured by the left camera 210L, and displays an error on the display 205 ( Step S180).

When the CPU 201 determines that the first register mark RM1 _L1 is included in the image at the first mark position PM1 captured by the left camera 210L (YES in step S186), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S187), the measurement position M1x1 _L in the X direction of the first register mark RM1 _L1 is calculated from the read count value X, and written to the address position in the X direction in the memory M19 (step S188). Further, the count value Y in the memory M5 at that time is read (step S189), the measurement position M1y1 _L in the Y direction of the first register mark RM1 _L1 is calculated from the read count value Y, and the Y direction in the memory M19 is calculated. Write to the address position (step S190, see FIG. 66 (c)).

Note that the measurement position M1x1 _{L in} the X direction of the register mark RM1 _L1 is obtained from the horizontal position where the left camera 210L is provided and the count value X, and the measurement position M1y1 _L in the Y direction is the first mark position PM1. It is obtained from the count value Y.

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 22: Step S191), sets the count value X in the memory M6 to 1 (Step S192), and sets the count value N in the memory M14 to 1 ( In step S193), the count value M in the memory M15 is set to 1 (step S194).

  The pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M12 is read (step S195), and the pixel of the first register mark at the address position (M, N) in the memory M16 is read. The data is read (step S196). The pixel data of the left camera at the address position (X + M-1, Y + N-1) in the memory M12 and the pixel data at the address position (M, N) in the memory M16 are read. (See step S197, FIGS. 68A and 68B).

Here, the pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M12 matches the pixel data of the first register mark at the address position (M, N) in the memory M16. If not (NO in step S197), any of the imaging data at the second mark position of the left camera 210L from the address (X, Y) to the address (X + c-1, Y + d-1) at that time Since the pixel data is different from the pixel data of the first register mark, the first register mark RM1 _{L2 on} the left of the second mark position PM2 does not exist in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 23: Step S198), the number of pixels a in the horizontal direction of the camera in the memory M8 and the first register mark in the memory M17. Lateral direction of reading the pixel number c of (step S199, S200), in step S201 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S193～S201.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S201), the left and right ends of the imaging data at the second mark position of the left camera 210L are exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S202), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels d in the vertical direction of the first register mark in the memory M18. Reading (steps S203 and S204), the processing operations of steps S192 to S205 are repeated until the count value Y exceeds “b−d + 1” in step S205.

  During this processing operation, the pixel data of the left camera at the (X + M−1, Y + N−1) address position in the memory M12 and the pixel data of the first register mark at the (M, N) address position in the memory M16. When it is confirmed that they match (FIG. 22: YES in step S197), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 24: step S207), and the first register mark is read from the memory M17. The left-right pixel number c is read (step S208), and the processing operations of steps S195 to S209 are repeated until the count value M exceeds the left-right pixel number c of the first register mark in step S209.

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S209), the CPU 201 adds 1 to the count value N in the memory M14 (step S210), and the first value from the memory M18. The number of pixels d in the vertical direction of the register mark is read (step S211), and the processing operations of steps S194 to S212 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first register mark in step S212.

In this way, the CPU 201 captures pixel data of the first register mark of c × d in the memory M16 with respect to imaging data of the pixel of a × b in the memory M12 (imaging data of the second mark position on the left). When the count value N exceeds the number of pixels d in the vertical direction of the first register mark (YES in step S212), the (X, Y) of the imaging data of the a × b pixel in the memory M12 is determined. It is determined that the pixel data of the c × d first register mark in the memory M16 is included in the range from the address to the address of (X + c−1, Y + d−1). That is, it is determined that the first register mark RM1 (RM1 _L2 ) is included in the image at the second mark position PM2 captured by the left camera 210L.

If the count value Y exceeds “b−d + 1” in step S205 (YES in step S205), it means that the top and bottom ends of the imaging data at the second mark position of the left camera 210L have been exceeded. Thus, the CPU 201 determines that the first register mark RM1 (RM1 _L2 ) is not included in the image at the second mark position PM2 captured by the left camera 210L, and displays an error on the display 205 ( Step S206).

When the CPU 201 determines that the first register mark RM1 _L2 is included in the image at the second mark position PM2 captured by the left camera 210L (YES in step S212), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S213), the measurement position M1x2 _L in the X direction of the first register mark RM1 _L2 is calculated from the read count value X, and written to the address position in the X direction in the memory M20 (step S214). Further, reads the count value Y in the memory M5 at that time (step S215), calculates the read count value Y from the measurement position in the Y direction of the first register mark RM1 _L2 M1y2 _L, in the memory M20 in the Y direction Write to the address position (step S216, see FIG. 68 (c)).

The measurement position M1x2 _{L in} the X direction of the register mark RM1 _L2 is obtained from the horizontal position where the left camera 210L is provided and the count value X, and the measurement position M1y2 _L in the Y direction is the second mark position PM2. It is obtained from the count value Y.

Then, CPU 201 reads the measurement position M1y1 _L in the Y direction of the first register mark RM1 _L1 at the first mark position PM1 than Y-direction address position of the memory M19 (Fig. 25: step S217), The second from the memory M21 reads the Y direction of the reference position M1y1r of the first register mark RM1 in the first mark position PM1 (step S218), the first register mark RM1 _L1 in the Y-direction measurement position M1y1 _L at the first mark position PM1 first the reference position M1y1r the Y direction of the first register mark RM1 and subtraction in mark position PM1, the first register mark RM1 _L1 seek Y direction deviation amount Derutaemu1y1 _L of the first mark position PM1 (FIG 66 (c) see ), The amount of deviation ΔM1 in the Y direction of the obtained first register mark RM1 _L1 y1 _L is written to the memory M22 (step S219).

Further, CPU 201 reads the first register mark RM1 _L1 in the Y-direction measurement position M1y1 _L at the first mark position PM1 than Y-direction address position of the memory M19 (step S220), the Y-direction address position of the memory M20 Then, the measurement position M1y2 _L in the Y direction of the first register mark RM1 _L2 at the second mark position PM2 is read (step S221), and the measurement position M1y1 _{L in} the Y direction of the first register mark RM1 _{L1 at} the first mark position PM1. than in the first register mark RM1 _L2 in the Y-direction measurement position M1y2 _L in the second mark position PM2 is subtracted obtains distances LM1 _L between the first register mark on the left (see FIG. 70 (a)), the calculated and writes the distance LM1 _L between the first register mark left in the memory M23 (step S222)

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 26: Step S223), sets the count value X in the memory M6 to 1 (Step S224), and sets the count value N in the memory M14 to 1 ( In step S225), the count value M in the memory M15 is set to 1 (step S226).

  Then, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M11 is read (step S227), and the pixel of the first register mark at the address position (M, N) in the memory M16. The data is read (step S228), the pixel data of the right camera at the address position (X + M-1, Y + N-1) in the memory M11 and the pixel data at the address position (M, N) in the memory M16 are read. Is confirmed (see step S229, FIGS. 67A and 67B).

Here, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M11 matches the pixel data of the first register mark at the address position (M, N) in the memory M16. If not (NO in step S229), one of the imaging data at the first mark position of the right camera 210R from the address (X, Y) at that time to the address (X + c-1, Y + d-1) Since the pixel data is different from the pixel data of the first register mark, the first register mark RM1 _R1 to the right of the first mark position PM1 does not exist in the range starting from the (X, Y) address. 1 is added to the count value X in M6 (FIG. 27: Step S230), the number of pixels a in the horizontal direction of the camera in the memory M8 and the first register marker in the memory M17. Reading a pixel number c in the horizontal direction (step S231, S232), in step S231 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S225～S233.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S233), it means that the left and right ends of the imaging data at the first mark position of the right camera 210R are exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S234), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels d in the vertical direction of the first register mark in the memory M18. Reading (steps S235 and S236), the processing operation of steps S224 to S237 is repeated until the count value Y exceeds “b−d + 1” in step S237.

  During this processing operation, the pixel data of the right camera at the (X + M−1, Y + N−1) address position in the memory M11 and the pixel data of the first register mark at the (M, N) address position in the memory M16. When it is confirmed that they match (FIG. 26: YES in step S229), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 28: step S239), and the first register mark is read from the memory M17. The left-right pixel number c is read (step S240), and the processing operations of steps S227 to S241 are repeated until the count value M exceeds the left-right pixel number c of the first register mark in step S241.

  When the count value M exceeds the number c of pixels in the left-right direction of the first register mark (YES in step S241), the CPU 201 adds 1 to the count value N in the memory M14 (step S242), and the first value from the memory M18. The pixel number d in the vertical direction of the register mark is read (step S243), and the processing operations of steps S226 to S244 are repeated until the count value N exceeds the vertical pixel number d of the first register mark in step S244.

In this manner, the CPU 201 captures pixel data of the first register mark of c × d in the memory M16 with respect to imaging data of the pixel of a × b in the memory M11 (imaging data of the first mark position on the right). When the count value N exceeds the number of pixels d in the vertical direction of the first register mark (YES in step S244), the (X, Y) of the imaging data of the a × b pixel in the memory M11 is determined. It is determined that the pixel data of the c × d first register mark in the memory M16 is included in the range from the address to the address of (X + c−1, Y + d−1). That is, it is determined that the first register mark RM1 (RM1 _R1 ) is included in the image at the first mark position PM1 captured by the right camera 210R.

If the count value Y exceeds “b−d + 1” in step S237 (YES in step S237), it means that the top and bottom ends of the imaging data at the first mark position of the right camera 210R are exceeded. Thus, the CPU 201 determines that the first register mark RM1 (RM1 _R1 ) is not included in the image at the first mark position PM1 captured by the right camera 210R, and displays an error on the display 205 ( Step S238).

If the CPU 201 determines that the first register mark RM1 _R1 is included in the image at the first mark position PM1 captured by the right camera 210R (YES in step S244), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S245), the measurement position M1x1 _R in the X direction of the first register mark RM1 _R1 is calculated from the read count value X, and written in the address position in the X direction in the memory M24 (step S246). Further, the count value Y in the memory M5 at that time is read (step S247), the measurement position M1y1 _R in the Y direction of the first register mark RM1 _R1 is calculated from the read count value Y, and the Y direction in the memory M24 is calculated. The address is written (see step S248, FIG. 67 (c)).

Note that the measurement position M1x1 _{R in} the X direction of the register mark RM1 _R1 is obtained from the horizontal position where the right camera 210R is provided and the count value X, and the measurement position M1y1 _R in the Y direction is the first mark position PM1. It is obtained from the count value Y.

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 29: step S249), sets the count value X in the memory M6 to 1 (step S250), and sets the count value N in the memory M14 to 1 ( In step S251), the count value M in the memory M15 is set to 1 (step S252).

  Then, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 is read (step S253), and the pixel of the first register mark at the address position (M, N) in the memory M16. The data is read (step S254), the pixel data of the right camera at the address position (X + M-1, Y + N-1) in the memory M13 and the pixel data at the address position (M, N) in the memory M16 are read. Is confirmed (see step S255, FIGS. 69 (a) and 69 (b)).

Here, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 matches the pixel data of the first register mark at the address position (M, N) in the memory M16. If not (NO in step S255), one of the imaging data at the second mark position of the right camera 210R from the address (X, Y) to the address (X + c-1, Y + d-1) at that time Since the pixel data is different from the pixel data of the first register mark, there is no first register mark RM1 _{R2 on} the right of the second mark position PM2 in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 30: step S256), the number of pixels a in the horizontal direction of the camera in the memory M8 and the first register marker in the memory M17. It reads the number c of the right and left direction pixel (step S257, S258), in step S259 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S251～S259.

  If the count value X exceeds “a−c + 1” during this processing operation (YES in step S259), it means that the left and right ends of the imaging data at the second mark position of the right camera 210R are exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S260), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels d in the vertical direction of the first register mark in the memory M18. Reading (steps S261 and S262), the processing operation of steps S250 to S263 is repeated until the count value Y exceeds “b−d + 1” in step S263.

  During this processing operation, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 and the pixel data of the first register mark at the address position (M, N) in the memory M16 are obtained. When it is confirmed that they match (FIG. 29: YES in step S255), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 31: step S265), and the first register mark is read from the memory M17. The horizontal pixel number c is read (step S266), and the processing operations of steps S253 to S267 are repeated until the count value M exceeds the horizontal pixel number c of the first register mark in step S267.

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S267), the CPU 201 adds 1 to the count value N in the memory M14 (step S268), and the first value from the memory M18. The number of pixels d in the vertical direction of the register mark is read (step S269), and the processing operations of steps S252 to S270 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first register mark in step S270.

In this manner, the CPU 201 captures pixel data of the first register mark of c × d in the memory M16 with respect to imaging data of the pixel of a × b in the memory M13 (imaging data of the second mark position on the right). When the count value N exceeds the number of pixels d in the vertical direction of the first register mark (YES in step S270), (X, Y) of the imaging data of the a × b pixel in the memory M13 It is determined that the pixel data of the c × d first register mark in the memory M16 is included in the range from the address to the address of (X + c−1, Y + d−1). That is, it is determined that the first register mark RM1 (RM1 _R2 ) is included in the image at the second mark position PM2 captured by the right camera 210R.

If the count value Y exceeds “b−d + 1” in step S263 (YES in step S263), it means that the top and bottom ends of the imaging data at the second mark position of the right camera 210R are exceeded. Thus, the CPU 201 determines that the first register mark RM1 (RM1 _R2 ) is not included in the image at the second mark position PM2 captured by the right camera 210R, and displays an error on the display unit 205 ( Step S264).

When the CPU 201 determines that the first register mark RM1 _R2 is included in the image at the second mark position PM2 captured by the right camera 210R (YES in step S270), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S271), the measurement position M1x2 _R in the X direction of the first register mark RM1 _R2 is calculated from the read count value X, and written in the address position in the X direction in the memory M25 (step S272). Further, reads the count value Y in the memory M5 at that time (step S273), calculates the read count value Y from the measurement position in the Y direction of the first register mark RM1 _R2 M1y2 _R, in the memory M25 in the Y direction The address is written (see step S274, FIG. 69 (c)).

Note that the measurement position M1x2 _{R in} the X direction of the register mark RM1 _R2 is obtained from the horizontal position where the right camera 210R is provided and the count value X, and the measurement position M1y2 _R in the Y direction is the second mark position PM2. It is obtained from the count value Y.

Then, the CPU 201 reads the measurement position M1y1 _R in the Y direction of the first register mark RM1 _{R1 at} the first mark position PM1 from the address position in the Y direction of the memory M24 (FIG. 32: step S275), and also from the memory M21. It reads the reference position M1y1r the Y direction of the first register mark RM1 in the first mark position PM1 (step S276), the first register mark RM1 measurement position _R1 in the Y-direction M1y1 _R at the first mark position PM1 first the reference position M1y1r the Y direction of the first register mark RM1 and subtraction in the mark position PM1, obtains a deviation amount Derutaemu1y1 _R in the Y direction of the first register mark RM1 _R1 at the first mark position PM1 (FIG 67 (c) see ), The amount of deviation ΔM1 in the Y direction of the obtained first register mark RM1 _R1 y1 _R is written into the memory M26 (step S277).

[Calculation of displacement amount of first register mark in first direction at first mark position]
Then, the CPU 201 reads the displacement amount ΔM1y1 _L in the Y direction of the first register mark RM1 _{L1 at} the first mark position PM1 on the left side of the memory M22 (step S278), and at the read left first mark position PM1. by adding the deviation amount Derutaemu1y1 _R in the Y direction of the first register mark RM1 _L1 in the Y direction deviation amount Derutaemu1y1 _L first register mark in the first mark position PM1 of right written in the memory M26 in RM1 _R1, this The sum of the amount of deviation ΔM1y1 _{L in} the Y direction of the first register mark RM1 _{L1 at} the left first mark position PM1 and the amount of deviation ΔM1y1 _{R in} the Y direction of the first register mark RM1 _{R1 at} the right first mark position PM1. The value is divided by 2 to obtain an average value ΔM1 of the first register mark RM1 at the left and right first mark positions PM1. y1 is obtained (ΔM1y1 = (ΔM1y1 _L + ΔM1y1 _R ) / 2), and the obtained average value ΔM1y1 of the first register mark RM1 at the left and right first mark positions PM1 is used as the first register mark RM1 at the first mark position PM1. Is written in the memory M27 as the amount of deviation ΔY1 in the Y direction (see step S279, FIGS. 70A, 70B, and 70C).

[Calculation of distance between first register marks]
Further, the CPU 201 reads the measurement position M1y1 _R in the Y direction of the first register mark RM1 _{R1 at} the first mark position PM1 from the address position in the Y direction of the memory M24 (step S280), and the address position in the Y direction of the memory M25. Load the first register mark RM1 _R2 in the Y direction of the measuring position M1y2 _R in the second mark position PM2 from (Figure 30: step S281), the measurement of the Y direction of the first register mark RM1 _R1 at the first mark position PM1 position M1y1 by subtracting the Y-direction measurement position M1y2 _R of the first register mark in than the second mark position PM2 _R RM1 _R2 determine the distance LM1 _R between the first register mark in the right (FIG. 70 (b) see) writes the distance LM1 _R between the first register mark on the right that this determined in the memory M28 (step S 82).

The CPU 201 reads the distance LM1 _L between the left first register marks from the memory M23 (step S283), and writes the right distance written in the memory M28 to the distance LM1 _L between the read left first register marks. The distance LM1 _R between the first register marks is added, and the total value of the distance LM1 _L between the left first register marks and the distance LM1 _R between the right first register marks is divided by 2, and left and right The average value LM1 of the distance between the register marks is calculated (LM1 = (LM1 _L + LM1 _R ) / 2). The distance between the register marks is written in the memory M29 (see step S284, FIGS. 70A, 70B, and 70D).

[Calculation of expansion / contraction ratio between first register marks]
The CPU 201 reads the reference distance LM1r between the first register marks from the memory M30 (step S285), and the distance between the pair of register marks in the vertical direction written in the memory M29 (between the left and right first register marks). LM1 is divided by the reference distance LM1r between the first register marks, and the result of division is defined as the expansion / contraction ratio η1 (η1 = LM1 / LM1r) between the pair of first register marks separated in the vertical direction. The data is written in the memory M31 (see step S286, FIG. 70 (e)).

〔printing〕
When the print start switch 208 is turned on after completion of this print preparation (FIG. 34: YES in step S287), the CPU 201 reads the reference print start position PRT _ST from the memory M32 (step S288). As shown in FIG. 71, the reference print start position PRT _ST is determined in advance as a reference print start position for the substrate 4A set on the table 3.

Then, the CPU 201 reads the amount of deviation ΔY1 in the Y direction of the first register mark RM1 at the first mark position PM1 from the memory M27 (step S289), and the second at the first mark position PM1 written in the memory M74. A deviation amount ΔY2 in the Y direction of the register mark RM2 is read (step S290), and the deviation amount ΔY1 in the Y direction of the first register mark RM1 at the first mark position PM1 is added to the reference print start position PRT _ST read in step S288. The corrected printing start position PRT _ST ′ is obtained by adding the Y-direction deviation amount ΔY2 of the second register mark RM2 at the first mark position PM1, and is written in the memory M33 (step S291). In this case, the shift amount ΔY1 in the Y direction of the first register mark RM1 at the first mark position PM1 is obtained as ΔY1 = ΔM1y1 in the previous step S279 (FIG. 32), and the second shift at the first mark position PM1. The shift amount ΔY2 in the Y direction of the register mark RM2 is set to ΔY2 = 0 in the previous step S101 (FIG. 13). Therefore, in this case, the corrected printing start position PRT _ST ', the first Y-direction of the first register mark RM1 at the mark position PM1 shift amount ΔY1 only a reference print start position PRT _ST of obtained in step S279 To obtain a corrected position.

  Next, the CPU 201 reads the printing length l determined for the substrate 4A from the memory M34 (step S292), and reads the expansion / contraction rate η1 between the first register marks from the memory M31 (step S293). The expansion ratio η2 between the second register marks is read from M77 (step S294), the print length l is multiplied by the expansion ratio η1 between the first register marks and the expansion ratio η2 between the second register marks, and the corrected printing is performed. The length l ′ (l ′ = l × η1 × η2) is obtained and written in the memory M35 (step S295). In this case, the expansion ratio η1 between the first register marks is obtained as η1 = LM1 / LM1r in the previous step S286 (FIG. 33), and the expansion ratio η2 between the second register marks is determined in the previous step S102 (FIG. 13). ), Η2 = 1. Therefore, in this case, the corrected printing length l ′ is obtained as a corrected length by multiplying the printing length l by only the expansion / contraction rate η1 between the first register marks obtained in step S286.

Then, the CPU 201 reads the corrected print start position PRT _ST ′ from the memory M33 (step S296), adds the corrected print length l ′ to the corrected print start position PRT _ST ′, and print end position PRT. _END is obtained, and the obtained print end position PRT _END is written in the memory M36 (step S297).

  Further, the CPU 201 reads the reference rotational speed VBr of the rubber cylinder from the memory M37 (FIG. 35: Step S298), reads the expansion / contraction rate η1 between the first register marks from the memory M31 (Step S299), and reads the second register from the memory M77. Reading the expansion / contraction ratio η2 between the marks (step S300) and multiplying the reference rotational speed VBr of the rubber cylinder by the inverse of the expansion / contraction ratio η1 between the first register marks and the inverse of the expansion ratio η2 between the second register marks. The rubber cylinder rotation speed VBp is obtained (VBp = VBr × 1 / η1 × 1 / η2), and the obtained rubber cylinder rotation speed VBp during printing is written in the memory M38 (step S301). In this case, the expansion ratio η1 between the first register marks is obtained as η1 = LM1 / LM1r in the previous step S286 (FIG. 33), and the expansion ratio η2 between the second register marks is determined in the previous step S102 (FIG. 13). ), Η2 = 1. Accordingly, in this case, the rotational speed VBp of the rubber cylinder during printing is obtained as a speed adjusted by multiplying the reference rotational speed VBr of the rubber cylinder by the reciprocal of the expansion / contraction ratio η1 between the first register marks obtained in step S286. It is done.

[Ink supply to plate cylinder]
Then, the CPU 201 reads the reference rotation speed VPr of the plate cylinder from the memory M39 (step S302), and the read reference rotation speed VPr of the plate cylinder is transferred to the plate cylinder driving motor driver 218 via the D / A converter 221. Output (step S303). As a result, the plate cylinder 1 starts to rotate at the reference rotation speed VPr.

  The CPU 201 outputs an ink supply start command to the inking device 235 while the plate cylinder 1 is rotated at the reference rotation speed VPr (step S304). As a result, ink starts to be supplied from the inking device 235 to the plate cylinder 1.

The CPU 201 reads the count value from the plate cylinder rotation phase detection counter 220 while the ink is being supplied from the inking device 235 to the plate cylinder 1 (step S305), and the read plate cylinder rotation phase detection counter 220 counts. calculates the current rotational phase phi _R of the plate cylinder than the value (step S306), reads the print start position phi _ST of the plate cylinder from the memory M42 (step S307), the current plate cylinder rotational phase phi _R is of the plate cylinder checks whether or not reached the print start position phi _ST (step S308).

When the CPU 201 confirms that the current rotation phase φ _R of the plate cylinder has reached the printing start position φ _ST of the plate cylinder (YES in step S308), the CPU 201 reads the count value from the plate cylinder rotation phase detection counter 220. (FIG. 36: Step S309), the current rotation phase φ _R of the plate cylinder is calculated from the read count value of the plate cylinder rotation phase detection counter 220 (Step S310), and the printing end position φ of the plate cylinder is stored from the memory M43. _END is read (step S306), and it is confirmed whether or not the current rotation phase φ _R of the plate cylinder has reached the printing end position φ _END of the plate cylinder (step S312).

When the CPU 201 confirms that the current rotational phase φ _R of the plate cylinder has reached the printing end position φ _END of the plate cylinder (YES in step S312), the CPU 201 outputs a stop command to the plate cylinder driving motor driver 218 ( In step S313), an ink supply stop command is output to the inking device 235 (step S314). This will interval supplied ink to the print start position phi _ST print end position phi _END from the plate cylinder 1, the rotation of the plate cylinder 1 in a state in which the ink is supplied is stopped.

[Ink transfer from plate cylinder to rubber cylinder]
Next, the CPU 201 reads the reference rotational speed VBr of the rubber cylinder from the memory M37 (step S315), and uses the read reference rotational speed VBr of the rubber cylinder to the rubber cylinder driving motor driver 223 via the D / A converter 226. (Step S316). As a result, the rubber cylinder 2 starts to rotate at the reference rotation speed VBr of the rubber cylinder. At this time, the rubber cylinder 2 is not in contact with the plate cylinder 1.

The CPU 201 rotates the rubber cylinder 2 at the reference rotation speed VBr, and then reads the count value from the rubber cylinder rotation phase detection counter 225 (FIG. 37: step S317), and the read rubber cylinder rotation phase detection counter 225 reads the count value. from the count value to calculate the current rotational phase [psi _R of the blanket cylinder (step S318), reads the print start position [psi _ST of the blanket cylinder from the memory M46 (step S319), the current rotational phase [psi _R is blanket cylinder of the blanket cylinder It is confirmed whether or not the print start position ψ _ST has been reached (step S320).

When the CPU 201 confirms that the current rotational phase ψ _R of the rubber cylinder has reached the print start position ψ _ST of the rubber cylinder (YES in step S320), the CPU 201 outputs a wearing command to the cylinder attaching / detaching device 236 (step S321). ) The rubber cylinder 2 is brought into contact with the plate cylinder 1. Then, the CPU 201 reads the reference rotation speed VPr of the plate cylinder from the memory M39 (step S322), and the read reference rotation speed VPr of the plate cylinder is transferred to the plate cylinder driving motor driver 218 via the D / A converter 221. Output (step S323). As a result, the plate cylinder 1 starts to rotate at the reference rotational speed VPr, and ink from the plate cylinder 1 starts to be transferred to the rubber cylinder 2.

While the ink is transferred from the plate cylinder 1 to the rubber cylinder 2, the CPU 201 reads the count value from the rubber cylinder rotation phase detection counter 225 (FIG. 38: step S324), and the read rubber cylinder rotation phase detection counter. The current rotation phase ψ _R of the rubber cylinder is calculated from the count value of 225 (step S325), the printing end position ψ _END of the rubber cylinder is read from the memory M47 (step S326), and the current rotation phase ψ _R of the rubber cylinder is obtained. It is confirmed whether or not the print end position ψ _END of the rubber cylinder has been reached (step S327).

When the CPU 201 confirms that the current rotational phase ψ _R of the rubber cylinder has reached the print end position ψ _END of the rubber cylinder (YES in step S327), the CPU 201 outputs a removal command to the cylinder attaching / detaching device 236 (step S328). ) The rubber cylinder 2 is separated from the plate cylinder 1. That is, the body is removed. As a result, the ink from the plate cylinder 1 is transferred to the section from the printing start position ψ _ST to the printing end position ψ _END of the rubber cylinder 2.

[Dropping of rubber cylinder]
When the transfer of the ink from the plate cylinder 1 to the rubber cylinder 2 is completed, the CPU 201 outputs a stop command to the plate cylinder driving motor driver 218 (step S329), and stops the rotation of the plate cylinder 1. Then, the count value is read from the rubber cylinder rotation phase detection counter 225 (FIG. 39: Step S330), and the current rotation phase ψ _R of the rubber cylinder is calculated from the read count value of the rubber cylinder rotation phase detection counter 225. (Step S331), the movement start position ψ _MST of the rubber cylinder is read from the memory M48 (Step S332), and it is confirmed whether or not the current rotation phase ψ _R of the rubber cylinder has reached the movement start position ψ _MST of the rubber cylinder. (Step S333).

When the CPU 201 confirms that the current rotational phase ψ _R of the rubber cylinder has reached the movement start position ψ _MST of the rubber cylinder (YES in step S333), the CPU 201 issues a lowering command to the air cylinder valve 234 for raising and lowering the rubber cylinder. Output (step S334). As a result, the rubber cylinder elevating air cylinder 233 is operated, and the rubber cylinder 2 is lowered onto the table 3 (see FIG. 72).

[Moving the rubber cylinder in the vertical direction]
Next, CPU 201 reads the vertical movement velocity vB _M of the blanket cylinder from the memory M49 (step S335), the vertical movement velocity vB _M of normal rotation instruction and the blanket cylinder to the blanket cylinder circumferential direction movement motor driver 228 D The data is output via the / A converter 231 (step S336). Thus, the blanket cylinder 2 is the downstream side in the circumferential direction while rotating, i.e. the direction of the substrate 4A on table 4, starts to move in vertical movement velocity vB _M.

Next, the CPU 201 writes “2” in the memory M50 as a value indicating that the correction of the phase deviation based on the vertical position of the rubber cylinder and the rotation phase has not been completed (FIG. 40: step S337). Then, while the rubber cylinder 2 is moving downstream in the vertical direction, the count value is read from the vertical position detection counter 230 of the rubber cylinder (step S338), and the vertical position detection counter 230 of the read rubber cylinder is read. The current top-to-bottom position PBM _R of the rubber cylinder is calculated from the counted value and written in the memory M52 (step S339), and the corrected print start position PRT _ST ′ is read from the memory M33 (step S340). It is checked whether or not the calculated vertical position PBM _R of the rubber cylinder has reached the corrected print start position PRT _ST ′ (step S341).

[Adjustment of rotational phase of rubber cylinder]
The CPU 201 proceeds to steps S342 (FIG. 41) to S362 (FIG. 42) until it is confirmed in step S341 that the current vertical position PBM _R of the rubber cylinder reaches the corrected print start position PRT _ST ′. Repeat the processing operation. In the processing of steps S342 to S362, the rotation phase of the rubber cylinder is adjusted. The adjustment of the rotational phase of the rubber cylinder is performed as follows.

The CPU 201 reads the current top-to-bottom position PBM _R of the rubber cylinder from the memory M52 (FIG. 41: step S342), and reads from the memory M27 the shift amount ΔY1 of the first register mark in the Y direction at the first mark position (step S342). S343), the amount of deviation ΔY2 in the Y direction of the second register mark at the first mark position is read from the memory M74 (step S344), and the first register at the first mark position is read into the current vertical position PBM _R of the rubber cylinder. The correction amount ΔY1 in the Y direction of the mark and the shift amount ΔY2 in the Y direction of the second register mark at the first mark position are added to obtain the corrected vertical position PBM _R ′ of the rubber cylinder. The corrected vertical position PBM _R ′ of the rubber cylinder is written in the memory M53 (step S345).

Then, from the memory M54, the vertical position of the rubber cylinder—the rotational phase conversion table of the rubber cylinder to be there is read (step S346). Using the corrected vertical position PBM _R ′ of the rubber cylinder, the rotational phase ψm of the rubber cylinder to be obtained is obtained (step S347).

The CPU 201 reads the count value from the rubber cylinder rotation phase detection counter 225 (step S348), and obtains the current rotation phase ψ _R of the rubber cylinder from the read count value of the rubber cylinder rotation phase detection counter 225 (step S348). Step S349). Then, the current rotational phase ψ _R of the rubber cylinder is subtracted from the rotational phase ψ m of the rubber cylinder that should be obtained in step S347 to obtain the current rotational phase difference Δψ _R of the rubber cylinder, and the obtained current rotational phase difference Δψ _R is written into the memory M56 (step S350).

Then, CPU 201 obtains an absolute value of the current rotational phase difference [Delta] [phi] _R of the current rotational phase difference [Delta] [phi] _R of the blanket cylinder of the blanket cylinder obtained in step S350 (step S351), the rotation position of the blanket cylinder from the memory M58 The allowable value α of the phase difference is read (step S352), and it is confirmed whether or not the absolute value of the current rotational phase difference Δψ _R of the rubber cylinder is less than or equal to the allowable value α of the rotational phase difference of the rubber cylinder (FIG. 42: step). S353).

If the absolute value of the current rotational phase difference Δψ _R of the rubber cylinder is not less than or equal to the allowable value α of the rotational phase difference of the rubber cylinder (NO in step S353), the CPU 201 reads the current rotation of the rubber cylinder from the memory M59. A correction value conversion table for phase difference-rotational speed is read (step S354), and the current rotational phase difference Δψ _R of the rubber cylinder is read from the memory M56 (step S355), and the current rotational phase difference of the rubber cylinder-rotational speed is calculated. A correction value ΔV of the rotational speed is obtained from the current rotational phase difference Δψ _R of the rubber cylinder using the correction value conversion table (step S356).

  The CPU 201 reads the reference rotation speed VBr of the rubber cylinder from the memory M37 (step S357), adds the correction value ΔV of the rotation speed to the reference rotation speed VBr of the rubber cylinder, and sets the corrected rotation speed VBr ′ of the rubber cylinder. Obtained (step S358), the obtained corrected rotational speed VBr ′ of the rubber cylinder is output to the rubber cylinder driving motor driver 223 via the D / A converter 226 (step S359), and then to step S338 (FIG. 40). Go back and repeat the same operation.

As a result, the rotational speed of the rubber cylinder 2 is adjusted, and the absolute value of the current rotational phase difference Δψ _R of the rubber cylinder is adjusted to be less than or equal to the allowable value α of the rotational phase difference of the rubber cylinder.

When the absolute value of the current rotational phase difference Δψ _R of the rubber cylinder becomes equal to or smaller than the allowable value α of the rotational phase difference of the rubber cylinder (FIG. 42: YES in step S353), the CPU 201 makes a reference rotation of the rubber cylinder from the memory M37. The speed VBr is read (step S360), and the read reference rotational speed VBr of the rubber cylinder is output to the rubber cylinder driving motor driver 223 via the D / A converter 226 (step S361). “1” is written as a value indicating that the correction of the phase deviation based on the vertical position and the rotational phase is completed (step S362).

The CPU 201 repeats the processing operations in steps S342 to S362 until the current top-to-bottom position PBM _R of the rubber cylinder reaches the corrected printing start position PRT _ST ′. Δψ when the absolute value of _R is not lower than the allowable value α of the rotation phase difference of the blanket cylinder, not proceed to the process to step S360～S362. In this case, “2” is still written in the memory M50 as a value indicating that the correction of the phase deviation based on the vertical position of the rubber cylinder and the rotational phase is not completed.

When the CPU 201 confirms that the current top-to-bottom position PBM _R of the rubber cylinder has reached the corrected print start position PRT _ST ′ (FIG. 40: YES in step S341), it reads the value written in the memory M50. (Step S363), it is confirmed whether or not the value written in the memory M50 is “1” (FIG. 43: Step S364). If the value written in the memory M50 is not “1” (NO in step S364), an error is displayed on the display 205 (step S377), but the value written in the memory M50 is “1”. "(YES in step S364), it is determined that the correction of the phase deviation based on the vertical position of the rubber cylinder and the rotational phase has been completed.

If the CPU 201 determines that the correction of the phase deviation based on the vertical position of the rubber cylinder and the rotation phase has been completed (YES in step S364), the CPU 201 reads the rotational speed VBp of the rubber cylinder being printed from the memory M38 (step S365). The read rotation speed VBp of the rubber cylinder being printed is output to the rubber cylinder driving motor driver 223 via the D / A converter 226 (step S366). As a result, the rubber cylinder 2 starts to rotate at the rotation speed VBp of the rubber cylinder during printing (see FIG. 73). That is, the rubber cylinder 2 moves to the downstream side in the vertical direction while rotating at the rotational speed VBp of the rubber cylinder being printed from the corrected printing start position PRT _ST ′, and with respect to the substrate 4A on the table 3 The circuit (second circuit) is printed.

Then, the CPU 201 reads the count value from the vertical position detection counter 230 of the rubber cylinder (step S367), and the current vertical position of the rubber cylinder from the read count value of the vertical position detection counter 230 of the rubber cylinder. PBM _R is calculated (step S368), the printing end position PRT _END is read from the memory M36 (step S369), and it is confirmed whether or not the current vertical position PBM _R of the rubber cylinder has reached the printing end position PRT _END. (Step S370).

When the CPU 201 confirms that the current vertical position PBM _R of the rubber cylinder has reached the print end position PRT _END (YES in step S370), the CPU 201 outputs a stop command to the rubber cylinder driving motor driver 223 (FIG. 41: Step S371), the rotation of the rubber cylinder 2 is stopped (see FIG. 74). Then, an ascent command is output to the rubber cylinder raising / lowering air cylinder valve 234 (step S372), and the rubber cylinder 2 is raised from the table 3 (see FIG. 75).

Then, CPU 201 reads the vertical movement velocity vB _M of the blanket cylinder from the memory M49 (step S373), the vertical movement velocity vB _M of the reverse rotation instruction and the blanket cylinder to the blanket cylinder circumferential direction movement motor driver 228 D / A The data is output via the converter 231 (step S374). Accordingly, the upstream side in the circumferential direction in a state in which the blanket cylinder 2 is stopped rotating, i.e. towards the side where the plate cylinder 1 is located, starts to move in the vertical movement velocity vB _M.

  When the origin position detector 232 in the vertical direction of the rubber cylinder is turned on by the movement of the rubber cylinder 2 in the vertical direction (YES in step S375), that is, the first time before the rubber cylinder 1 starts moving. When returning to the position (origin position), a stop command is output to the rubber cylinder top movement motor driver 228 (step S376). This stops the movement of the rubber cylinder 2 in the vertical direction (see FIG. 76).

  As a result, the first circuit is printed with the amount of displacement ΔY2 of the second register mark in the Y direction at the first mark position PM1 as ΔY2 = 0 and the expansion / contraction rate η2 between the second register marks as η2 = 1. The circuit (second circuit) is printed on the printed material 4A, and the first printed material 4B on which the four second register marks RM2 are simultaneously printed as shown in FIG. 3 is obtained.

[Teaching after printing]
The operator thus turns on the teaching switch 209 after completion of printing after obtaining the printed material 4B on which the four second register marks RM2 are simultaneously printed.

  When the teaching switch 209 after printing is turned on (FIG. 45: YES in step S377), the CPU 201 of the flatbed printing control apparatus 200 reads the rotational speed Vc of the camera moving motor from the memory M1 (step S378). A normal rotation command and the rotation speed Vc of the camera moving motor are output to the camera moving motor driver 212 via the D / A converter 215 (step S379). As a result, the camera moving motor 211 rotates forward at the rotation speed Vc, and the left camera 210L and the right camera 210R simultaneously move leftward on the table 3 with the initial position shown in FIG.

While the left camera 210L and the right camera 210R are moving, the CPU 201 reads the count value of the camera position detection counter 214 (step S380), and the left camera 210L and the right camera 210R are read based on the count value of the camera position detection counter 214. The current position PCM _R is calculated (step S381), the first mark position PM1 is read from the memory M4 (step S382), and the current positions PCM _R of the left camera 210L and the right camera 210R have reached the first mark position PM1. Whether or not (step S383).

When the CPU 201 confirms that the current position PCM _R of the left camera 210L and the right camera 210R has reached the first mark position PM1 (YES in step S383), it outputs a stop command to the camera movement motor driver 212 ( Step S384), the movement of the left camera 210L and the right camera 210R is stopped. Then, an imaging command is output to the left camera 210L and the right camera 210R (step S385), and an area including the second register mark RM2 _R1 on the printed material 4B set in the table 3 is imaged by the left camera 210L. An area including the second register mark RM2 _R1 on the printed material 4B is captured by the right camera 210R.

  Then, the CPU 201 sends an imaging data transmission command to the left camera 210L (FIG. 46: step S386). When imaging data is sent from the left camera 210L in response to this transmission command (YES in step S387), the memory The count value Y in M5 is set to 1 (step S388), the count value X in the memory M6 is set to 1 (step S389), and the imaging data from the left camera 210L at the pixel position specified by the count values X and Y is stored in the memory. Write to the address position of (X, Y) in M7 (step S390).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S391), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S392), and the count value X is determined by the camera in step S393. The processing operations in steps S390 to S393 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the pixel number a in the left-right direction of the camera (YES in step S393), 1 is added to the count value Y in the memory M5 (step S394), and the camera in the memory M9 in the top-to-bottom direction. The number of pixels b is read (step S395), and the processing operations of steps S389 to S396 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S396.

Thereby, the imaging data of the a × b pixel from the left camera 210L at the first mark position PM1 is stored in the memory M7. Here, as shown in FIG. 77 (a), the imaging data including the second register mark RM2 _L1 of the substrate 4B is stored in the memory M7 as an imaging data of the pixels of a × b. In the memory M62, as shown in FIG. 77B, e × f pixel data of the second register mark RM2 is stored as data for pattern matching.

  Next, the CPU 201 sends an imaging data transmission command to the right camera 210R (FIG. 47: Step S397). When imaging data is sent from the right camera 210R in response to this transmission command (YES in Step S398), The count value Y in the memory M5 is set to 1 (step S399), the count value X in the memory M6 is set to 1 (step S400), and the imaging data from the right camera 210R at the pixel position specified by the count values X and Y is obtained. Write to the address position (X, Y) in the memory M11 (step S401).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S402), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S403), and the count value X is read from the camera in step S404. The processing operations in steps S401 to S404 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the left-right direction of the camera (YES in step S404), 1 is added to the count value Y in the memory M5 (step S405), and the vertical direction of the camera in the memory M9 is increased. The number of pixels b is read (step S406), and the processing operations of steps S400 to S407 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S407.

Thereby, the imaging data of the a × b pixel from the right camera 210R at the first mark position PM1 is stored in the memory M11. Here, as shown in FIG. 78A, the imaging data including the second register mark RM2 _R1 of the substrate 4B is stored in the memory M11 as imaging data of a × b pixels.

  Next, the CPU 201 reads the rotational speed Vc of the camera moving motor from the memory M1 (FIG. 48: step S408), and performs a D / A conversion on the reverse rotation command to the camera moving motor driver 212 and the rotational speed Vc of the camera moving motor. The data is output via the device 215 (step S409). As a result, the camera moving motor 211 reverses at the rotation speed Vc, and the left camera 210L and the right camera 210R that have stopped at the first mark position PM1 in FIG. 3 simultaneously move on the table 3 in the right direction.

While the left camera 210L and the right camera 210R are moving, the CPU 201 reads the count value of the camera position detection counter 214 (step S410), and the left camera 210L and the right camera 210R are read based on the count value of the camera position detection counter 214. The current position PCM _R is calculated (step S411), the second mark position PM2 is read from the memory M10 (step S412), and the current positions PCM _R of the left camera 210L and the right camera 210R have reached the second mark position PM2. Whether or not (step S413).

When confirming that the current position PCM _R of the left camera 210L and the right camera 210R has reached the second mark position PM2 (YES in step S413), the CPU 201 outputs an imaging command to the left camera 210L and the right camera 210R ( In step S414), an area including the second register mark RM2 _L2 on the substrate 4B is imaged by the left camera 210L, and an area including the second register mark RM2 _R2 on the substrate 4B is imaged by the right camera 210R.

  Then, the CPU 201 sends an imaging data transmission command to the left camera 210L (step S415). When imaging data is sent from the left camera 210L in response to this transmission command (YES in step S416), the CPU 201 stores the imaging data in the memory M5. The count value Y is set to 1 (step S417), the count value X in the memory M6 is set to 1 (FIG. 49: step S418), and the imaging data from the left camera 210L at the pixel position specified by the count values X and Y is stored in the memory. Write to the address position (X, Y) of M12 (step S419).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S420), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S421), and the count value X is determined by the camera in step S422. The processing operations in steps S419 to S422 are repeated until the number of pixels a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the left-right direction of the camera (YES in step S422), 1 is added to the count value Y in the memory M5 (step S423), and the camera in the vertical direction of the camera in the memory M9. The number of pixels b is read (step S424), and the processing operations of steps S418 to S425 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S425.

Thereby, the imaging data of the a × b pixel from the left camera 210L at the second mark position PM2 is stored in the memory M12. Here, as shown in FIG. 79A, the imaging data including the second register mark RM2 _L2 of the substrate 4B is stored in the memory M12 as imaging data of a × b pixels.

  Next, the CPU 201 sends an imaging data transmission command to the right camera 210R (step S426). When imaging data is sent from the right camera 210R in response to the transmission command (YES in step S427), the CPU 201 stores the imaging data in the memory M5. 1 is set to 1 (FIG. 50: step S428), the count value X in the memory M6 is set to 1 (step S429), and the imaging data from the right camera 210R at the pixel position specified by the count values X and Y is obtained. Write to the address position (X, Y) in the memory M13 (step S430).

  Then, the CPU 201 adds 1 to the count value X in the memory M6 (step S431), reads the number of pixels a in the left-right direction of the camera in the memory M8 (step S432), and the count value X is read from the camera in step S433. The processing operations in steps S430 to S433 are repeated until the pixel number a in the left-right direction is exceeded.

  If the count value X exceeds the number of pixels a in the left-right direction of the camera (YES in step S433), 1 is added to the count value Y in the memory M5 (step S434), and the vertical direction of the camera in the memory M9 is increased. The number of pixels b is read (step S435), and the processing operations of steps S429 to S436 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the camera in step S436.

Thereby, the imaging data of the a × b pixel from the right camera 210R at the second mark position PM2 is stored in the memory M13. Here, as shown in FIG. 80A, the imaging data including the second register mark RM2 _R2 of the substrate 4B is stored in the memory M13 as imaging data of a × b pixels.

  Then, the CPU 201 continues to move the left camera 210L and the right camera 210R, and when the camera origin position detector 216 detects the return to the origin position (initial position) of the left camera 210L and the right camera 210R (step S437). YES), a stop command is sent to the camera movement motor driver 212 (step S438), and the movement of the left camera 210L and the right camera 210R is stopped.

[Detection of second register mark position by pattern matching]
Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 51: step S439), sets the count value X in the memory M6 to 1 (step S440), and sets the count value N in the memory M14 to 1 ( In step S441), the count value M in the memory M15 is set to 1 (step S442).

  The pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M7 is read (step S443), and the pixel of the second register mark at the address position (M, N) in the memory M62. The data is read (step S444). The pixel data of the left camera at the address position (X + M-1, Y + N-1) in the memory M7 and the pixel data at the address position (M, N) in the memory M62 are read. (See step S445, FIGS. 77 (a) and 77 (b)).

Here, the pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M7 matches the pixel data of the second register mark at the address position (M, N) in the memory M62. If not (NO in step S445), one of the imaging data at the first mark position of the left camera 210L from the address (X, Y) to the address (X + e-1, Y + f-1) at that time Since the pixel data is different from the pixel data of the second register mark, there is no second register mark RM2 _{L1 on} the left of the first mark position PM1 in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 52: Step S446), the number of pixels a in the horizontal direction of the camera in the memory M8 and the second register mark in the memory M63. Reading a pixel number e in the horizontal direction (step S447, S448), in step S449 until the count value X exceeds "a-e + 1", and repeats the processing operation in steps S441～S449.

  If the count value X exceeds “a−e + 1” during this processing operation (YES in step S449), it means that the left and right ends of the imaging data at the first mark position of the left camera 210L have been exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S450), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels f in the vertical direction of the second register mark in the memory M64. Reading (steps S451 and S452), the processing operations of steps S440 to S453 are repeated until the count value Y exceeds “b−f + 1” in step S453.

  During this processing operation, the pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M7 and the pixel data of the second register mark at the address position (M, N) in the memory M62 are obtained. When it is confirmed that they match (FIG. 51: YES in step S445), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 53: step S455), and the second register mark is read from the memory M63. The horizontal pixel number e is read (step S456), and the processing operations of steps S443 to S457 are repeated until the count value M exceeds the horizontal pixel number e of the second register mark in step S457.

  When the count value M exceeds the pixel number e in the left-right direction of the second register mark (YES in step S457), the CPU 201 adds 1 to the count value N in the memory M14 (step S458), and the second value from the memory M64. The number of pixels f in the vertical direction of the register mark is read (step S459), and the processing operations of steps S442 to S460 are repeated until the count value N exceeds the number of pixels f in the vertical direction of the second register mark in step S460.

In this manner, the CPU 201 captures pixel data of the e × f second register mark in the memory M62 with respect to the imaging data of the a × b pixel in the memory M7 (imaging data at the left first mark position). When the count value N exceeds the number of pixels f in the vertical direction of the second register mark (YES in step S460), (X, Y) of the imaging data of the a × b pixel in the memory M7 It is determined that the pixel data of the second register mark of e × f in the memory M62 is included in the range from the address to the address of (X + e−1, Y + f−1). That is, it is determined that the second register mark RM2 (RM2 _L1 ) is included in the image at the first mark position PM1 captured by the left camera 210L.

If the count value Y exceeds “b−f + 1” in step S453 (YES in step S453), it means that the top and bottom ends of the imaging data at the first mark position of the left camera 210L have been exceeded. Thus, the CPU 201 determines that the second register mark RM2 (RM2 _L1 ) is not included in the image at the first mark position PM1 captured by the left camera 210L, and displays an error on the display unit 205 ( Step S454).

When the CPU 201 determines that the second register mark RM2 _L1 is included in the image at the first mark position PM1 captured by the left camera 210L (YES in step S460), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S461), the measurement position M2x1 _L in the X direction of the second register mark RM2 _L1 is calculated from the read count value X, and written in the address position in the X direction in the memory M65 (step S462). Further, the count value Y in the memory M5 at that time is read (step S463), the measurement position M2y1 _L in the Y direction of the second register mark RM2 _L1 is calculated from the read count value Y, and the Y direction in the memory M65 is calculated. Write to the address position (see step S464, FIG. 77 (c)).

The X-direction measurement position M2x1 _L of the register mark RM2 _L1 is obtained from the left-right position where the left camera 210L is provided and the count value X, and the Y-direction measurement position M2y1 _L is the first mark position PM1. It is obtained from the count value Y.

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 54: step S465), sets the count value X in the memory M6 to 1 (step S466), and sets the count value N in the memory M14 to 1 ( In step S467, the count value M in the memory M15 is set to 1 (step S468).

  The pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M12 is read (step S469), and the pixel of the second register mark at the address position (M, N) in the memory M62. The data is read (step S470). The pixel data of the left camera at the address position (X + M-1, Y + N-1) in the memory M12 and the pixel data at the address position (M, N) in the memory M62 are read. Are confirmed (see step S471, FIGS. 79A and 79B).

Here, the pixel data of the left camera at the address position (X + M−1, Y + N−1) in the memory M12 matches the pixel data of the second register mark at the address position (M, N) in the memory M62. If not (NO in step S471), any one of the imaging data at the second mark position of the left camera 210L from the address (X, Y) to the address (X + e-1, Y + f-1) at that time Since the pixel data is different from the pixel data of the second register mark, there is no second register mark RM2 _{L2 on} the left of the second mark position PM2 in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 55: step S472), the number of pixels a in the left-right direction of the camera in the memory M8 and the second register mark in the memory M63. It reads the number e of the right and left direction pixel (step S473, S474), in step S475 until the count value X exceeds "a-e + 1", and repeats the processing operation in steps S467～S475.

  If the count value X exceeds “a−e + 1” during this processing operation (YES in step S475), it means that the left and right ends of the imaging data at the second mark position of the left camera 210L have been exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S476), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels f in the vertical direction of the second register mark in the memory M64. Reading is performed (steps S477 and S478), and the processing operations of steps S466 to S479 are repeated until the count value Y exceeds “b−f + 1” in step S479.

  During this processing operation, the pixel data of the left camera at the (X + M−1, Y + N−1) address position in the memory M12 and the pixel data of the second register mark at the (M, N) address position in the memory M62 are obtained. When it is confirmed that they match (FIG. 54: YES in step S471), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 56: step S481), and the second register mark is read from the memory M63. The horizontal pixel number e is read (step S482), and the processing operations of steps S469 to S483 are repeated until the count value M exceeds the horizontal pixel number e of the second register mark in step S483.

  When the count value M exceeds the number e of pixels in the left-right direction of the second register mark (YES in step S483), the CPU 201 adds 1 to the count value N in the memory M14 (step S484), and the second value from the memory M64. The number of pixels f in the vertical direction of the register mark is read (step S485), and the processing operations of steps S468 to S486 are repeated until the count value N exceeds the number of pixels f in the vertical direction of the second register mark in step S486.

In this way, the CPU 201 captures pixel data of the e × f second register mark in the memory M62 with respect to the imaging data of the a × b pixel in the memory M12 (imaging data at the left second mark position). When the count value N exceeds the number of pixels f in the vertical direction of the second register mark (YES in step S486), (X, Y) of the imaging data of the a × b pixel in the memory M12 is obtained. It is determined that the pixel data of the second register mark of e × f in the memory M62 is included in the range from the address to the address of (X + e−1, Y + f−1). That is, it is determined that the second register mark RM2 (RM2 _L2 ) is included in the image at the second mark position PM2 captured by the left camera 210L.

If the count value Y exceeds “b−f + 1” in step S479 (YES in step S479), it means that the top and bottom ends of the imaging data at the second mark position of the left camera 210L have been exceeded. Thus, the CPU 201 determines that the second register mark RM2 (RM2 _L2 ) is not included in the image at the second mark position PM2 captured by the left camera 210L, and displays an error on the display unit 205 ( Step S480).

When the CPU 201 determines that the second register mark RM2 _L2 is included in the image at the second mark position PM2 captured by the left camera 210L (YES in step S486), the CPU 201 obtains the count value X in the memory M6 at that time. Reading (step S487), the measurement position M2x2 _L in the X direction of the second register mark RM2 _L2 is calculated from the read count value X, and written to the address position in the X direction in the memory M66 (step S488). Further, reads the count value Y in the memory M5 at that time (step S489), calculates the measurement position M2y2 _L of the read from the count value Y of the second register mark RM2 _L2 Y-direction, in the memory M66 in the Y direction Write to the address position (step S490, see FIG. 79 (c)).

The measurement position M2x2 _{L in} the X direction of the register mark RM2 _L2 is obtained from the horizontal position where the left camera 210L is provided and the count value X, and the measurement position M2y2 _L in the Y direction is the second mark position PM2. It is obtained from the count value Y.

Then, CPU 201 reads the second register mark RM2 measurement position _L1 in the Y-direction M2y1 _L in the Y-direction address location than the first mark position PM1 in the memory M65 (Fig. 57: step S491) first from The memory M67 reads the Y direction of the reference position M2y1r of the second register mark RM2 at the first mark position PM1 (step S492), the second register mark RM2 _L1 in the Y-direction measurement position M2y1 _L at the first mark position PM1 first the reference position M2y1r the Y direction of the second register mark RM2 and subtraction in mark position PM1, first determine the shift amount Derutaemu2y1 _L in the Y direction of the second register mark RM2 _L1 at the mark position PM1 (FIG 77 (c) see ), The amount of deviation ΔM2 in the Y direction of the obtained second register mark RM2 _L1 y1 _L is written into the memory M68 (step S493).

Further, CPU 201 reads the second register mark RM2 _L1 in the Y-direction measurement position M2y1 _L at the first mark position PM1 than Y-direction address position of the memory M65 (step S494), the Y-direction address position of the memory M66 Then, the measurement position M2y2 _L in the Y direction of the second register mark RM2 _{L2 at} the second mark position PM2 is read (step S495), and the measurement position M2y1 _{L in} the Y direction of the second register mark RM2 _L1 at the first mark position PM1. than in the second register mark RM2 _L2 in the Y-direction measurement position M2y2 _L in the second mark position PM2 subtracting seek distance LM2 _L between the second register mark on the left (see FIG. 81 (a)), the calculated and writes the distance LM2 _L between the second register mark on the left in the memory M69 (step S496)

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 58: step S497), sets the count value X in the memory M6 to 1 (step S498), and sets the count value N in the memory M14 to 1 ( In step S499, the count value M in the memory M15 is set to 1 (step S500).

  Then, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M11 is read (step S501), and the pixel of the second register mark at the address position (M, N) in the memory M62. Data is read (step S502). The pixel data of the right camera at the address position (X + M-1, Y + N-1) in the memory M11 and the pixel data at the address position (M, N) in the memory M62 are read. Is confirmed (see step S503, FIGS. 78 (a) and 78 (b)).

Here, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M11 coincides with the pixel data of the second register mark at the address position (M, N) in the memory M62. If not (NO in step S503), one of the imaging data at the first mark position of the right camera 210R from the address (X, Y) at that time to the address (X + e-1, Y + f-1) Since the pixel data is different from the pixel data of the second register mark, the first register mark RM2 _R1 to the right of the first mark position PM1 does not exist in the range starting from the (X, Y) address. 1 is added to the count value X in M6 (FIG. 59: step S504), the number of pixels a in the horizontal direction of the camera in the memory M8 and the second register mark in the memory M63. Lateral direction of reading the pixel number e of (step S505, S506), in step S507 until the count value X exceeds "a-e + 1", and repeats the processing operation in steps S499～S507.

  If the count value X exceeds “a−e + 1” during this processing operation (YES in step S507), it means that the left and right ends of the imaging data at the first mark position of the right camera 210R are exceeded. The PU 201 adds 1 to the count value Y in the memory M5 (step S508), and calculates the number of pixels b in the vertical direction of the camera in the memory M9 and the number of pixels f in the vertical direction of the second register mark in the memory M64. Reading (steps S509 and S510), the processing operations of steps S498 to S511 are repeated until the count value Y exceeds “b−f + 1” in step S511.

  During this processing operation, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M11 and the pixel data of the second register mark at the address position (M, N) in the memory M62 are obtained. When it is confirmed that they match (FIG. 58: YES in step S503), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 60: step S513), and the second register mark is read from the memory M63. The horizontal pixel number e is read (step S514), and the processing operations of steps S501 to S515 are repeated until the count value M exceeds the horizontal pixel number e of the second register mark in step S515.

  When the count value M exceeds the left-right pixel number e of the second register mark (YES in step S515), the CPU 201 adds 1 to the count value N in the memory M14 (step S516), and the second value from the memory M64. The number of pixels f in the vertical direction of the register mark is read (step S517), and the processing operations of steps S500 to S518 are repeated until the count value N exceeds the number of pixels f in the vertical direction of the second register mark in step S518.

In this manner, the CPU 201 captures pixel data of the e × f second register mark in the memory M62 with respect to the imaging data of the a × b pixel in the memory M11 (imaging data at the first mark position on the right). When the count value N exceeds the number of pixels f in the vertical direction of the second register mark (YES in step S518), (X, Y) of the imaging data of the a × b pixel in the memory M11 It is determined that the pixel data of the second register mark of e × f in the memory M62 is included in the range from the address to the address of (X + e−1, Y + f−1). That is, it is determined that the second register mark RM2 (RM2 _R1 ) is included in the image at the first mark position PM1 captured by the right camera 210R.

If the count value Y exceeds “b−f + 1” in step S511 (YES in step S511), it means that the top and bottom ends of the imaging data at the first mark position of the right camera 210R are exceeded. Thus, the CPU 201 determines that the second register mark RM2 (RM2 _R1 ) is not included in the image at the first mark position PM1 captured by the right camera 210R, and displays an error on the display unit 205 ( Step S512).

When the CPU 201 determines that the second register mark RM2 _R1 is included in the image at the first mark position PM1 captured by the right camera 210R (YES in step S518), the count value X in the memory M6 at that time is determined. Reading (step S519), the measurement position M2x1 _R in the X direction of the second register mark RM2 _R1 is calculated from the read count value X, and written in the address position in the X direction in the memory M70 (step S520). Further, the count value Y in the memory M5 at that time is read (step S521), the measurement position M2y1 _R in the Y direction of the second register mark RM2 _R1 is calculated from the read count value Y, and the Y direction in the memory M70 is calculated. The address is written (see step S522, FIG. 78 (c)).

Note that the measurement position M2x1 _{R in} the X direction of the register mark RM2 _R1 is obtained from the horizontal position where the right camera 210R is provided and the count value X, and the measurement position M2y1 _R in the Y direction is the first mark position PM1. It is obtained from the count value Y.

  Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 61: step S523), sets the count value X in the memory M6 to 1 (step S524), and sets the count value N in the memory M14 to 1 ( In step S525), the count value M in the memory M15 is set to 1 (step S526).

  Then, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 is read (step S527), and the pixel of the second register mark at the address position (M, N) in the memory M62. Data is read (step S528), the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 and the pixel data at the address position (M, N) in the memory M62 are read. (See step S529, FIGS. 80A and 80B).

Here, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 matches the pixel data of the second register mark at the address position (M, N) in the memory M62. If not (NO in step S529), one of the imaging data at the second mark position of the right camera 210R from the address (X, Y) at that time to the address (X + e-1, Y + f-1) Since the pixel data is different from the pixel data of the second register mark, the first register mark RM2 _R2 to the right of the second mark position PM2 does not exist in the range starting from the address (X, Y). 1 is added to the count value X in M6 (FIG. 62: step S530), the number of pixels a in the left-right direction of the camera in the memory M8 and the second register mark in the memory M63. It reads the number e of the right and left direction pixel (step S531, S532), in step S533 until the count value X exceeds "a-e + 1", and repeats the processing operation in steps S525～S533.

  During this processing operation, if the count value X exceeds “a−e + 1” (YES in step S533), this means that the left and right ends of the imaging data at the second mark position of the right camera 210R are exceeded. The CPU 201 adds 1 to the count value Y in the memory M5 (step S534), and calculates the vertical pixel count b of the camera in the memory M9 and the vertical pixel count f of the second register mark in the memory M64. Reading (steps S535 and S536), and the processing operation of steps S524 to S537 is repeated until the count value Y exceeds “b−f + 1” in step S537.

  During this processing operation, the pixel data of the right camera at the address position (X + M−1, Y + N−1) in the memory M13 and the pixel data of the second register mark at the address position (M, N) in the memory M62 are obtained. When it is confirmed that they match (FIG. 61: YES in step S529), the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 63: step S539), and the second register mark is read from the memory M63. The left-right pixel number e is read (step S540), and the processing operations in steps S527 to S541 are repeated until the count value M exceeds the left-right pixel number e of the second register mark in step S541.

  When the count value M exceeds the left-right pixel number e of the second register mark (YES in step S541), the CPU 201 adds 1 to the count value N in the memory M14 (step S542), and the second value from the memory M64. The number of pixels f in the vertical direction of the register mark is read (step S543), and the processing operations of steps S526 to S544 are repeated until the count value N exceeds the number of pixels f in the vertical direction of the second register mark in step S544.

In this way, the CPU 201 captures pixel data of the e × f second register mark in the memory M62 with respect to imaging data of the a × b pixel in the memory M13 (imaging data at the right second mark position). When the count value N exceeds the number of pixels f in the vertical direction of the second register mark (YES in step S544), (X, Y) of the imaging data of the a × b pixel in the memory M13 It is determined that the pixel data of the second register mark of e × f in the memory M62 is included in the range from the address to the address of (X + e−1, Y + f−1). That is, it is determined that the second register mark RM2 (RM2 _R2 ) is included in the image at the second mark position PM2 captured by the right camera 210R.

If the count value Y exceeds “b−f + 1” in step S537 (YES in step S537), it means that the top and bottom ends of the imaging data at the second mark position of the right camera 210R have been exceeded. Thus, the CPU 201 determines that the second register mark RM2 (RM2 _R2 ) is not included in the image at the second mark position PM2 captured by the right camera 210R, and displays an error on the display unit 205 ( Step S538).

When the CPU 201 determines that the second register mark RM2 _R2 is included in the image at the second mark position PM2 captured by the right camera 210R (YES in step S544), the CPU 201 calculates the count value X in the memory M6 at that time. Reading (step S545), the measurement position M2x2 _R in the X direction of the second register mark RM2 _R2 is calculated from the read count value X, and written in the address position in the X direction in the memory M71 (step S546). Further, it reads the count value Y in the memory M5 at that time (step S547), calculates the read count value Y from the measurement position in the Y direction of the second register mark RM2 _R2 M2y2 _R, in the memory M71 in the Y direction Write to the address position (step S548, see FIG. 80C).

The X-direction measurement position M2x2 _R of the register mark RM2 _R2 is obtained from the left-right direction position where the right camera 210R is provided and the count value X, and the Y-direction measurement position M2y2 _R is the second mark position PM2. It is obtained from the count value Y.

Then, the CPU 201 reads the measurement position M2y1 _R in the Y direction of the second register mark RM2 _R1 at the first mark position PM1 from the address position in the Y direction of the memory M70 (FIG. 64: step S549), and also from the memory M67. It reads the reference position M2y1r the Y direction of the second register mark RM2 at the first mark position PM1 (step S550), the second register mark RM2 measurement position _R1 in the Y-direction M2y1 _R at the first mark position PM1 first A reference position M2y1r in the Y direction of the second register mark RM2 at the mark position PM1 is subtracted to obtain a deviation amount ΔM2y1 _R in the Y direction of the second register mark RM2 _R1 at the first mark position PM1 (see FIG. 78 (c)). ), The amount of deviation ΔM2 in the Y direction of the obtained second register mark RM2 _R1 y1 _R is written into the memory M72 (step S551).

[Calculation of Y-direction deviation amount of second register mark at first mark position]
Then, the CPU 201 reads the amount of deviation ΔM2y1 _L in the Y direction of the second register mark RM2 _L1 at the first mark position PM1 on the left side of the memory M68 (step S552), and at the read left first mark position PM1. by adding the deviation amount Derutaemu2y1 _R in the Y direction of the second register mark RM2 _L1 in the Y direction deviation amount Derutaemu2y1 _L second register mark in the first mark position PM1 of right written in the memory M72 to RM2 _R1, this The sum of the amount of deviation ΔM2y1 _{L in} the Y direction of the second register mark RM2 _{L1 at} the left first mark position PM1 and the amount of deviation ΔM2y1 _{R in} the Y direction of the second register mark RM2 _{R1 at} the right first mark position PM1 By dividing the value by 2, the average value ΔM2 of the second register mark RM2 at the left and right first mark positions PM1 y1 is obtained (ΔM2y1 = (ΔM2y1 _L + ΔM2y1 _R ) / 2), and the obtained average value ΔM2y1 of the second register mark RM2 at the left and right first mark positions PM1 is written in the memory M73 (step S553).

  Then, the amount of deviation ΔY1 (ΔM1y1) in the Y direction of the first register mark RM1 at the first mark position PM1 is read from the memory M27 (step S554), and the average value ΔM2y1 of the second register mark RM2 at the first mark position PM1 is read. Accordingly, the amount of deviation ΔY1 (ΔM1y1) in the Y direction of the first register mark RM1 at the first mark position PM1 is subtracted, and the amount of deviation ΔY2 in the Y direction of the second register mark RM2 at the first mark position (ΔY2 = ΔM2y1−). ΔM1y1) is obtained, and the amount of deviation ΔY2 in the Y direction of the second register mark RM2 at the obtained first mark position is written in the memory M74 (see step S555, FIGS. 81A, 81B, 81C). .

[Calculation of distance between second register marks]
Further, the CPU 201 reads the measurement position M2y1 _R in the Y direction of the second register mark RM2 _R1 at the first mark position PM1 from the address position in the Y direction of the memory M70 (FIG. 65: step S556), and the Y direction of the memory M71. reads the measuring position M2y2 _R of the second register mark RM2 _R2 Y direction from the address position in the second mark position PM2 (step S557), the measurement of the Y direction of the second register mark RM2 _R1 at the first mark position PM1 position M2y1 by subtracting the Y-direction measurement position M2y2 _R of the second register mark RM2 _R2 from _R at the second mark position PM2 seek distance LM2 _R between the second register mark in the right (FIG. 81 (b) see) writes the distance LM2 _R between the second register mark on the right that this determined in the memory M75 (step S 58).

The CPU 201 reads the distance LM2 _L between the left second register marks from the memory M69 (step S559), and writes the right LM2 _L written in the memory M75 to the distance LM2 _L between the read left second register marks. The distance LM2 _R between the second register marks is added, and the total value of the distance LM2 _L between the left second register marks and the distance LM2 _R between the right second register marks is divided by 2, and left and right The average value LM2 of the distance between the register marks is calculated (LM2 = (LM2 _L + LM2 _R ) / 2), and the calculated average value LM2 between the left and right register marks is used as a pair of second register marks in the vertical direction. The distance is written in the memory M76 (see step S560, FIGS. 81 (a), (b), (d)).

[Calculation of expansion / contraction ratio between second register marks]
Then, the CPU 201 reads the distance between the first register marks (average value of the distance between the left and right first register marks) LM1 from the memory M29 (step S561), and between the second register marks written in the memory M76. The distance (average value of the distance between the left and right second register marks) LM2 is divided by the distance LM1 between the first register marks, and the division result is the expansion / contraction rate η2 between the pair of second register marks separated in the vertical direction. (Η2 = LM2 / LM1) is written in the memory M77 (see step S562, FIG. 81 (e)).

[Next printing]
After performing the teaching after the completion of printing in this way, the operator replaces the printing material 4B (the printing material 4 on which the second circuit is printed) with the next printing material 4A (the first circuit is printed). The printed substrate 4) is set on the table 3 (see FIGS. 1 and 2), and the print preparation start switch 207 is turned on (step S103 (FIG. 13)).

  Then, the CPU 201 of the flatbed printing control apparatus 200 confirms that the print preparation start switch 207 is turned on (FIG. 13: YES in step S103), and “register mark imaging” and “pattern matching” are performed in the same manner as described above. "Detection of the position of the first register mark", "Calculation of the shift amount of the first register mark in the Y direction at the first mark position", "Calculation of the distance between the first register marks", "Between the first register marks Calculating the expansion / contraction ratio ”, obtaining a displacement amount ΔY1 (ΔM1y1) in the Y direction of the first register mark RM1 at the first mark position PM1 from the printing material 4A set on the table 3, and writing it in the memory M27. The expansion / contraction ratio η1 (η1 = LM1 / LM1r) between the first register marks is obtained and written in the memory M31.

  When the print start switch 208 is turned on after completion of the preparation for printing (FIG. 34: YES in step S287), the CPU 201 performs the next object set on the table 3 in the same manner as described above. A second circuit is printed on the printed material 4A. At the time of printing the circuit for the second time, the CPU 201 detects not only the amount of deviation ΔY1 in the Y direction of the first register mark RM1 at the first mark position PM1 obtained from the current printing material 4A written in the memory M27, The amount of deviation ΔY2 in the Y direction of the second register mark RM2 at the first mark position PM1 obtained from the previous substrate 4B is used. Further, not only the expansion / contraction rate η1 between the first register marks obtained from the current printing material 4A written in the memory M31 but also the expansion / contraction rate η2 between the second register marks obtained from the previous printing material 4B is used.

That is, in step S291 (FIG. 34), the amount of deviation ΔY1 in the Y direction of the first register mark RM1 at the first mark position PM1 and the second register mark RM2 at the first mark position PM1 at the reference print start position PRT _ST . The Y-direction deviation amount ΔY2 is added to obtain a corrected print start position PRT _ST ′. In step S295 (FIG. 34), the print length l is set to the expansion / contraction ratio η1 between the first register marks and the second register mark. The corrected printing length l ′ (l ′ = l × η1 × η2) is obtained by multiplying the expansion ratio η2 between them. In step S301 (FIG. 35), the rubber cylinder being printed by multiplying the reference rotation speed VBr of the rubber cylinder by the reciprocal number of the expansion ratio η1 between the first register marks and the reciprocal number of the expansion ratio η2 between the second register marks. Rotation speed VBp (VBp = VBr × 1 / η1 × 1 / η2), and in step S345 (FIG. 41), the current register position of the first register mark at the first mark position is set to the current vertical position PBM _R of the rubber cylinder. By adding the amount of deviation ΔY1 in the Y direction and the amount of deviation ΔY2 in the Y direction of the second register mark at the first mark position, the corrected vertical position PBM _R ′ of the rubber cylinder is obtained.

  In this way, in the present embodiment, the second circuit is printed on the printed material 4A on which the first circuit is printed in the pre-processing step. The printing start position is not only adjusted in accordance with the amount of deviation ΔY1 in the Y direction of the first register mark RM1 of the printed material 4A and the amount of deviation ΔY2 in the Y direction of the second register mark RM2 of the previous printed material 4B. The expansion ratio η1 of the current printing material 4A obtained before printing from the distance LM1 between the first registration marks RM1 and the previous printing material 4B obtained from the distance LM2 between the second registration marks RM2. According to the expansion / contraction ratio η2 of the printed section, the rotational speed of the rubber cylinder 2 is adjusted when the second circuit is printed (when the second circuit is printed), and the first printing is performed. Circuit and second time It becomes the position of the printed circuit is precisely tailored.

  In the above-described embodiment, the rubber cylinder 2 is moved in the vertical direction. However, the table 3 on which the printing material 4A is set may be moved in the vertical direction.

In the above-described embodiment, the pair of first register marks RM1 separated in the vertical direction are printed on the left and right of the substrate 4A in the preprocessing step, but as shown in FIG. 82 (a). A pair of first register marks RM1 (RM1 _c1 , RM1 _c2 ) separated in the vertical direction may be printed at the center of the substrate 4A. As shown in FIG. 82B, the substrate 4A A pair of first register marks RM1 (RM1 _c1 , RM1 _c2 ) that are separated in the vertical direction only in the center may be printed. The same applies to the pair of second register marks RM2 printed on the substrate 4B.

  When a pair of first register mark RM1 and second register mark RM2 that are separated from each other only in the center of the substrate 4A is printed, an area including the first register mark RM1 and the second register mark RM2 is imaged. Only one camera is required, and the processing in the flatbed printing control apparatus 200 is simplified.
