The two positioning pins 2c provided on the table 2 are positioned so that the left tangent LN1 in contact with them is parallel to the side surface 2e of the table 2.
Further, since the side surface 2e is formed in parallel with the side surface 2d, the tangent LN1 is set in parallel to the side surface 2d and the side surface 2e. Here, the distance in the left-right direction between the tangent line LN1 and the side surface 2e is defined as a distance D1 (see FIG. 1).
Further, the side surface 2d and the side surface 2e of the table 2 are positioned so as to be orthogonal to the extending direction of the rail 3, that is, the moving direction of the table 2.

The image line portion forming position P1 where the table 2 is located is a position where the side surface 2d is in contact with the reference contact portion 1c, and the processing position P2 is a position where the side surface 2e is in contact with the reference contact portion 1d.

This positioning accuracy is maintained with high accuracy over time and in repeated operations.

(Regarding the image line forming device 52)
The image line forming device 52 includes a front auxiliary table 4f positioned in front of the table 2 at the image line forming position P1, and a rear auxiliary table 4r positioned in the rear. The heights of the upper surface 4f1 and the upper surface 4r1 of the front auxiliary table 4f and the rear auxiliary table 4r are the same as the height of the upper surface 2a of the table 2.

The rear auxiliary table 4r is provided with two positioning pins 4r2 that move up and down and protrude from the upper surface 4r1 in the left-right direction.
The positioning pin 4r2 moves up and down in conjunction with the positioning pin 2c provided on the table 2 under the control of the control device CT.
Further, the separation direction of the two positioning pins 4r2 and the separation direction of the two positioning pins 2c are orthogonal to each other.

  As shown in FIG. 1, the original plate Wa moves upward and comes into contact with a positioning pin 2c protruding from the upper surface 2a and a positioning pin 4r2 protruding from the upper surface 4r1, so that the holding position on the table 2 is maintained. Is decided. That is, it is positioned. The positioned original plate material Wa is sucked and held on the table 2 by air suction through the suction holes 2b. Details of the positioning suction holding will be described later.

Is done.

The image line forming device 52 includes a gate-shaped beam 5 that is erected upward and extends in the front-rear direction on the left side and the right side of the table 2 at the image line area forming position P1 on the pedestal 1. Yes.
A stay 6 extending in the left-right direction is suspended between the pair of beams 5 and 5 so as to be movable in the front-rear direction. The stay 6 is moved in the front-rear direction by a stay drive unit KD4 (see FIG. 5). The operation of the stay driving unit KD4 is controlled by the control device CT.

A head portion 7 is attached to the stay 6 so as to be movable in the left-right direction.

The control unit CT controls the ink ejection in the ink head 7a, the ultraviolet irradiation in the ultraviolet irradiation unit 7b, and the operation of the head driving unit KD5.

With this configuration, the image line forming device 52 moves the ink head 7a to the surface of the original plate Wa positioned by the positioning pins 2c and 4r2 through the cooperation of the back and forth movement of the stay 6 and the left and right movement of the head portion 7. It moves two-dimensionally and forms an image part GB based on the image data GJ2.
The drawing line data GJ2 is included in drawing line information GJ1 described later. The control device CT controls ink ejection of the ink head 7a based on the image line data GJ2.
By this ink ejection, ink adheres to the surface of the original plate material Wa in a pattern corresponding to the image line data GJ2. The adhering ink is cured by the ultraviolet irradiation from the ultraviolet irradiation section 7b and becomes the image line section GB.

  When the image line portion GB is formed, the ink head 7a ejects ink while moving in the left-right and front-rear directions close to the surface of the original plate Wa. For this reason, in the formation operation of the image line portion GB, the positioning pins 2c and 4r2 are lowered and sunk to prevent interference with the ink head 7a.

In a state where the positioning pins 2c and 4r2 are submerged, the ink head 7a can discharge ink to the entire area of the surface of the original plate Wa.
In other words, the image line forming device 52 can form the image line GB in an arbitrary range for the entire area of the surface of the original plate Wa.
Thereby, the image line portion forming device 52 can also form the image line portion GB in a bent portion Wb2 (described later) formed by the processing device 53.

As shown in FIG. 1, in the image line forming device 52, the movement of the stay 6 in the front-rear direction is based on the tangent line LN1 on the left side with respect to the two positioning pins 2c of the table 2, and is parallel to the tangent line LN1. To be done.
On the other hand, the tangent line LN2 on the front side with respect to the two positioning pins 4r2 of the rear auxiliary table 4r is set to be orthogonal to the tangent line LN1 in a top view.
The movement of the head portion 7 in the left-right direction is performed in parallel with the tangent line LN2 with the tangent line LN2 as a reference.
Here, the distance in the front-rear direction between the tangent LN2 and the rear side surface 2f of the table 2 is defined as a distance D2.

When the control device CT recognizes that the side surface 2d of the table 2 is in contact with the reference contact portion 1c based on the detection signal SN2d, the control device CT reduces the output of the table drive unit KD1, and the side surface 2d is in contact with the reference by an external force. It is biased weakly so as to be stably maintained without leaving the part 1c.

  In the positioning state of the image line forming device 52, the front and rear sides Wa1 and the left and right sides Wa2 of the original plate Wa that are orthogonal to each other are pressed against the positioning pin 2c and the positioning pin 4r2, respectively, by a carry-in device or a manual operation. Thereby, the front and rear sides Wa1 and the left and right sides Wa2 of the original plate Wa are positioned so as to match the positions of the tangent line LN1 and the tangent line LN2, respectively.

(Suction retention of original plate material Wa)
The two positioning pins 2c are provided with sensors SS1 and SS2 (FIG. 5) which are pressure sensitive sensors, respectively. The two positioning pins 4r2 are provided with pressure sensitive sensors SS3 and SS4 (FIG. 5), respectively.
When the original plate material Wa contacts, the sensors SS1 to SS4 send contact detection signals SN1 to SN4 (FIG. 5) indicating contact to the control device CT.
When the control device CT grasps that all of the contact detection signals SN1 to SN4 indicate contact, it determines that the positioning of the original plate Wa has been completed, operates the suction pump KD2, and sucks air from the suction hole 2b. To start.
The original plate material Wa is sucked and held on the table 2 by this air suction. This state is referred to as a suction holding state of the original plate material Wa.

(Formation of the image line GB)
When the suction holding is stabilized after a lapse of a predetermined time from the start of suction, the control device CT operates the table pin drive unit KD3 to lower the positioning pin 2c and the positioning pin 4r2 so that they are sunk from the upper surface 2a and the upper surface 4r1. .
As a result, the ink head 7a can move without interfering with other members over the entire surface of the original plate Wa.

The control device CT forms the image line GB based on the image line information GJ1 supplied from the outside and stored in the storage unit 56.
As shown in FIGS. 8 and 9, the image line information GJ1 includes image line data GJ2 of an image to be printed and position data GJ3 that forms the image line part GB.
The image line data GJ2 includes reference position information GJ2a indicating the reference position GB1 in the image line portion GB.
The position data GJ3 includes a distance D3 that is a distance in the width direction from the front and rear sides Wa1 and a distance D4 that is a distance in the circumferential direction from the left and right sides Wa2 that specify the position of the position GB1 with respect to the original plate Wa.

The control device CT refers to the image line information GJ1, and in the left-right direction, a distance (D1 + D3) obtained by adding the distance D1 and the distance D3 from the side surface 2e to the front and rear side Wa1, and in the front-rear direction, from the rear side surface 2f to the left and right side Wa2. The image line is formed with the position where the distance D2 is the distance D4 or the reduced other distance (D4-D2) as the position GB1 serving as the reference of the image area GB.
That is, the formation position of the image portion GB is determined based on the positions of the side surface 2e and the rear side surface 2f of the table 2.
The control device CT operates the stay drive unit KD4 and the head drive unit KD5 based on the image line data GJ2, and moves the stay 6 in the front-rear direction and the head unit 7 in the left-right direction. At the same time, the ink is ejected from the ink head 7a toward the original plate Wa. The ink adhering to the original plate material Wa is irradiated with ultraviolet rays from the ultraviolet irradiation unit 7b and cured, and a two-dimensional image line GB is formed in a predetermined range of the original plate material Wa to obtain a printing plate intermediate Wb. .

(Conveying plate intermediate Wb)
When the printing plate intermediate Wb is obtained, the control device CT operates the table driving unit KD1 to move the printing plate intermediate Wb to the processing position P2. During this movement, the suction pump KD2 is continuously operated to suck and hold the printing plate intermediate Wb on the table 2.
When the control device CT grasps that the side surface 2e is in contact with the reference contact portion 1d by the detection signal SN2e, the control device CT determines that the table 2 has reached the processing position P2, and reduces the output of the table drive portion KD1. The side surface 2e is weakly biased so as not to be separated from the reference contact portion 1d.

(Processing of printing plate intermediate Wb)
The control device CT sets the puncher 11b of the processing device 53 in the retracted position and the bending unit 12 in the standby position in advance.
The control device CT first executes punching.

The control device CT operates the punch base drive unit KD6 to remove the punch base 11a from the retracted position and approach the table 2, and the overhanging portion Wb3 of the printing plate intermediate Wb is relatively positioned between the punch 11b1 and the die 11b2. To enter.
When the front-rear direction position of the punch 11b1 reaches a predetermined position, the punch driving unit KD7 is operated to form the hole Wb1 in the printing plate intermediate body Wb (FIG. 8).

Here, as shown in FIG. 8, the position in the front-rear direction of the predetermined position is a position that is directed forward by a distance Ds from the left and right sides Wa2 of the printing plate intermediate Wb.
The control device CT monitors the detection signal SN11 from the detection unit SS11, and when the value of the distance D6 decreases and coincides with the value of the distance D2, the center position CL11 of the punch 11b1 is set to the left and right sides Wa2 of the printing plate intermediate Wb. Judged to be in the corresponding position. Furthermore, the movement is stopped when the value of the distance D6 becomes a value obtained by subtracting the value of the distance Ds from the value of the distance D2. This stop position is a predetermined position of the puncher 11b, that is, a punch position.
As a result, a hole Wb1 is formed with the center and the position separated from the left and right sides Wa2 of the printing plate intermediate body Wb by a distance Ds as shown in FIG.

  That is, the center position of the hole Wb1 is determined with respect to the side surface 2e of the table 2 in the left-right direction and the position in the front-rear direction is determined with reference to the rear side surface 2f of the table 2. As described above, the image line GB of the printing plate intermediate body Wb is positioned and formed with high accuracy with respect to the side surface 2e and the rear side surface 2f of the table 2, so that the hole Wb1 is substantially the image line. It is formed with reference to the formation position of the part GB.

  When the punching process is completed, the control device CT operates the punch base drive unit KD6 to move the punch base 11a to the retracted position.

As described above with reference to FIGS. 6A and 6B, the control device CT operates the bar driving unit KD8 and the bar rotation driving unit KD9 with respect to the overhanging portion Wb3 in which the hole Wb1 is formed. And bending according to the shape of the anvil 12a.
Here, as shown in FIG. 10, the bending unit 12 arranged on the rear side is formed such that the position of the fold line LN4 is a distance D7 from the rear side surface 2f of the table 2 at the processing position P2 toward the rear. Are arranged to be. Further, the bending unit 12 disposed on the front side is disposed such that the position of the bending line LN5 is formed at a distance D8 from the front side surface 2g of the table 2 at the processing position P2 toward the front. . Specifically, the anvil 12a is disposed so that the tip position thereof corresponds to the position of the distance D7 and the position of the distance D8.

Thus, since the position of the fold line LN4 is positioned with reference to the front side surface 2g and the rear side surface 2f of the table 2, the fold portion Wb2 is formed substantially with reference to the formation position of the image line portion GB. The
When the bending process is completed, the control device CT operates the bar driving unit KD8 to raise the bending unit 12 and move it to the standby position.

  The printing plate intermediate Wb on which the image line part GB is formed is punched and bent by the processing device 53 to become a printing plate Wc. The plate Wc is unloaded to the right in FIG. 1 by an unillustrated unloader or manual operation.

As described above in detail, the image forming unit 52 of the plate making system 51 includes the stay 6 that translates the image line GB with respect to the original plate material Wa with respect to the tangent LN1 of the two positioning pins 2c, and the tangent. It is formed by an ink head 7a that moves two-dimensionally by the movement of the head portion 7 that moves parallel to the tangent LN2 of the two positioning pins 4r2 orthogonal to LN1.
The original plate material Wa is positioned and held with respect to the table 2 at positions where two adjacent sides coincide with the tangent line LN1 and the tangent line LN2, respectively.
The formation position of the image line portion GB is defined by the distance D3 in the left-right direction from the tangent LN1 of the reference position GB1 and the distance D4 in the front-rear direction from the tangent LN2.
The tangent line LN1 is set at a distance D1 parallel to the side surface 2e of the table 2. Further, the tangent line LN2 is set at a distance D2 parallel to the rear side surface 2f of the table 2.
That is, the position of the image line GB formed on the original plate Wa is determined by using the side surface 2e of the table 2 on which the original plate Wa is positioned and sucked and held as a reference in the left-right direction, and the rear side surface 2f as the reference in the front-rear direction. Is set.

  The printing plate intermediate body Wb in which the image line portion GB is formed on the original plate material Wa is conveyed to the processing device 53 while being positioned and sucked and held by the table 2 by the image line portion forming apparatus 52.

In the processing apparatus 53, in the state where the table 2 is at the processing position P2, the front-rear direction position of the rear side surface 2f in the table 2 is used as a reference in the front-rear direction of drilling, and the left-right direction position of the side surface 2e is the reference in the left-right direction of drilling. As a result, punching is performed by the puncher 11b around a position separated from each reference by a predetermined distance.
That is, the punching position for punching is substantially performed based on the position of the image line portion GB that mediates the side surface 2e and the rear side surface 2f.

Further, in the bending process of forming the bent part Wb2 by bending the overhanging part Wb3 of the printing plate intermediate body Wb with the table 2 in the processing position P2, the front-rear direction of the anvil 12a that determines the front-rear direction position of the folding line LN4 The position is set at a position separated from the reference by a predetermined distance with respect to the position in the front-rear direction of the rear side surface 2f of the table 2.
That is, the bending position of the bent portion Wb2 is substantially performed with reference to the position of the image line portion GB that mediates the rear side surface 2f.

As described above, the plate making system 51 can perform punching and bending without performing a new positioning operation by the processing device 53, and therefore does not require an image detection means for positioning.
Thereby, the plate making system 51 does not increase the number of parts for new positioning and does not increase the cost. Further, since the plate making system 51 does not perform a position detection operation for positioning in the processing device 53, the plate making efficiency is improved.

  The embodiment is not limited to the above-described configuration and procedure, and may be modified in a range not departing from the gist of the present invention.

(Modification)
The plate making system 51 of the embodiment has been described as including only the moving table 2 as a table. However, as a modification, the plate making system 61 including both a moving table and a fixed table may be used.

The plate making system 61 includes an image line forming device 62, a processing device (press plate intermediate processing device) 63, a transport device 64, and a control device (not shown). The control device corresponds to the control device CT, and controls the entire operation of the plate making system 61 in sway with the control device CT.
The image line portion forming device 62 and the processing device 63 are different from the image line portion forming device 52 and the processing device 53 in the embodiment in that they have a fixed table 22 and a fixed table 23, respectively. Further, the transport device 64 has a moving table 25 instead of the table 2 of the transport device 54.
11 and 12 are schematic top views in which only the table portion is extracted for explaining the plate making system 61. FIG.

As shown in FIG. 12, the fixed table 22 provided in the image line portion forming device 62 includes a plurality of arm portions 22a extending in the left-right direction and arranged in parallel in the front-rear direction, and connecting the arm portions 22a on the left side. It has a portion 22b and is formed in a comb shape in which the space between the arm portions 22a is released to the right. The upper surface 22a1 of each arm 22a has the same height.
That is, the fixed table 22 is formed as a concave portion between the adjacent arm portions 22a in a top view.
A rear auxiliary table 22c is arranged on the rear side of the fixed table 22, and a front auxiliary table 22d is arranged on the front side.

Positioning pins 22a2 are provided on the rearmost arm portion 22a and the foremost arm portion 22a. The positioning pin 22a2 moves up and down so that it can protrude and retract with respect to the upper surface 22a1 of the arm portion 22a.
Positioning pins 22c1 are also provided on the rear auxiliary table 22c so as to be separated in the left-right direction. The positioning pin 22c1 is movable in and out of the upper surface 22c2 of the rear auxiliary table 22c in conjunction with the positioning pin 22a2.

Each arm 22a is provided with a plurality of suction holes 22a3 (indicated by black circles in FIGS. 11 and 12).
The suction hole 22a3 sucks air by the operation of a suction pump (not shown). Thereby, the original plate material Wa or the printing plate intermediate body Wb placed on the arm portion 22a can be sucked and held.
The operations of the positioning pin 22a2, the positioning pin 22c1, and the suction pump are controlled by a control device (not shown).

As shown in FIG. 11, the fixed table 23 provided in the processing device 63 includes a plurality of arm portions 23 a extending in the left-right direction, and a connecting portion 23 b that connects the arm portions 23 a on the right side. The arm portion 23a is formed in a comb shape that is released to the left.
That is, the fixed table 22 is formed as a concave portion between the adjacent arm portions 23a as viewed from above. The upper surface 23a1 of each arm 23a has the same height.
The outer shape of the fixed table 23 in a top view is a symmetrical shape obtained by horizontally inverting the fixed table 22.
The fixed table 23 is not provided with the positioning pins 22a2 and the suction holes 22a3 provided on the fixed table 22. However, a suction hole corresponding to the suction hole 22a3 may be provided.
An anvil 24 for bending is arranged in the vicinity of the rear and front of the fixed table 23, respectively.

The moving table 25 has a plurality of entry table portions 25a that enter between the arm portions 22a and 23a of the fixed tables 22 and 23 and place and support the original plate material Wa and the printing plate intermediate body Wb together with the fixed tables 22 and 23.
The moving table 25 moves on a rail (not shown) between an upstream position P3 that has entered the fixed table 22 and a downstream position P4 that has entered the fixed table 23 by the operation of a driving unit (not shown).

The upstream position P3 is a reference position corresponding to an image line forming position in the table 2. The downstream position P4 is a reference position corresponding to the machining position on the table 2.
In FIG. 11, the state in the upstream position P3 of the movement table 25 and the state in the middle of movement are both shown by the solid line.
FIG. 12 shows a state at the downstream position P4 of the moving table 25.

Each entry table portion 25a has a plurality of suction holes 25a1 and sucks air by operation of a suction pump (not shown). Thereby, the moving table 25 can suck and hold the placed original plate material Wa or printing plate intermediate Wb alone.
The suction hole 22a3 provided in the fixed table 22 and the suction hole 25a1 provided in the entry table portion 25a can be independently turned ON / OFF. This ON / OFF is controlled by a control device.

  In the plate making system 61 described above, the printing plate intermediate Wb obtained by the image line portion forming device 62 is conveyed to the processing device 63 by the moving table 25 and processed while the processing device 63 is executing the image line portion. The next original plate material Wa can be positioned and sucked and held on the fixed table 22 of the forming apparatus 62 to form the image line portion GB. For details, follow the procedure below.

First, as shown in FIG. 11, the control device positions the moving table 25 at the upstream position P3. The positioning pins 22a2 and 22c1 are raised to a protruding state.
The original plate material Wa is placed on the fixed table 22 and the moving table 25 and abutted against the positioning pins 22a2 and 22c1 by a carry-in device (not shown) or manually.
The position in the left-right direction of the original plate Wa abutted against the positioning pin 22a2 is set based on the position of the right side surface 25e when the moving table 25 is at the upstream position P3. The position in the front-rear direction is set with reference to the position of the rear side surface 25f.
That is, the original plate material Wa is positioned based on the positions of the side surface 25e and the rear side surface 25f of the moving table 25 mediated by the positions of the positioning pins 22a2 and 22c1, respectively.
The control device operates the suction pump to suck air from the suction hole 22a3 and the suction hole 25a1. Thereby, the original plate material Wa is sucked and held by the fixed table 22 and the moving table 25.

The control device lowers the positioning pins 22a2 and 22c1 and immerses them in the table, and then moves the head unit (not shown) to form the image line GB in a predetermined range of the original plate Wa. The formation procedure of the image line GB is the same as that of the plate making system 51.
The position where the image line GB is formed is substantially determined by using the front and back sides Wa1 and the left and right sides Wa2 of the original plate Wa as a mediation, and the side surface 25e of the moving table 25 in the left-right direction and the moving table 25 in the front-back direction. The rear side surface 25f is set as a reference.

When the printing plate intermediate Wb is obtained by forming the image line GB, the control device stops the suction by the suction hole 22a3 of the fixed table 22 and moves while maintaining the suction of the suction hole 25a1 of the moving table 25. The table 25 is moved toward the downstream position P4 (shown at the center position in FIG. 11). In this moving state, the printing plate intermediate Wb is positioned and held by the moving table 25.
That is, the positional relationship between the moving table 25 and the printing plate intermediate body Wb is maintained in the positioning state of the original plate material Wa at the upstream position P3.

When the moving table 25 reaches the downstream position P4 (FIG. 12), the control device executes punching and bending in this order for the plate intermediate body Wb that is sucked and held.
The positions for punching and bending the printing plate intermediate Wb are set with respect to the side surface 25e of the moving table 25 in the left-right direction. Further, the front-rear direction is set with reference to the rear side surface 25f of the moving table 25.
The punching and bending procedures are the same as those in the plate making system 51.

When the printing plate intermediate Wb is processed to obtain the printing plate Wc, the control device stops the suction of the suction hole 25a1 of the moving table 25 and moves the moving table 25 toward the upstream position P3. At this time, since the printing plate Wc remains supported by the fixed table 23, it is carried out to the outside by an unillustrated unloading device or manually.
While the plate intermediate body Wb is being processed, the next original plate material Waa is carried into the fixed table 22 by a carry-in device (not shown) or manually (arrow Db). When the original plate Waa is positioned by contacting the positioning pin 22a2 and the positioning pin 22c1, the control device positions and holds the original material Waa by suction of the suction hole 22a3.
An image line GB is formed on the next original plate material Waa that has been positioned and held.

  If the formation of the image portion GB on the next original plate Waa has not yet been completed when the movement table 25 starts moving from the downstream position P4 to the upstream position P3, the control device moves the movement table 25 in the middle. Stop and stand by, and after the formation of the image line GB is completed, move to the upstream position P3. Further, if the image line part GB has already been formed on the next original plate material Waa, it is moved to the upstream position P3 without being stopped.

When the moving table 25 reaches the upstream position P3, the control device starts sucking through the suction hole 25a1 of the moving table 25, and moves the next printing plate intermediate Wbb held by the fixed table 22 to the moving table 25. But suck and hold.
Thereafter, a plurality of printing plates are made by repeating the above operation.

  As described above, according to the plate making system 61, the image line portion GB can be formed on the next original plate material Wa by the image line portion forming device 62 while the processing device 63 performs the processing. As a result, the number of printing plates that can be made per unit time is increased, so that the plate making efficiency is improved.

  The position determination method in the movement of each member is not limited to the method using the pressure sensor as described above, and a known method can be applied. For example, each drive unit may be provided with an encoder and the position may be determined based on the output.

  The part of the table that serves as a reference for the formation position of the image line GB and the positions of punching and bending may not be the side surface 2e and the rear side surface 2f described above. A positioning reference portion that has been positioned with high precision is provided on the bottom surface of the moving tables 2 and 25, or other positioning members are attached to the moving tables 2 and 25 as a reference portion. A reference site may be provided.

  The processing device 53 is not limited to one that performs both punching and bending. The plate making system may have a separate punching device and bending device. In this case, the moving tables 2 and 25 are configured to be movable between the punching device and the bending device.

In the embodiment and the modification, the example in which the image line forming devices 52 and 62 and the processing devices 53 and 63 are provided on the common pedestal 1 has been described. Also good.
Further, the installation distance between the image line forming devices 52 and 62 and the processing devices 53 and 63 is not limited to a close distance. For example, both devices may be installed on different floors.
Therefore, the movement tables 2 and 25 are not limited to those that move linearly as described above.
The mode of the trajectory of movement is not limited.
This is because the formation position of the image line portion GB and the formation positions of punching and bending are set with reference to predetermined portions of the moving tables 2 and 25. The moving tables 2 and 25 are the original plate material Wa and the printing plate intermediate. This is because the trajectories of the moving tables 2 and 25 are not restricted by moving while positioning and holding Wb.

In the embodiment described in detail above and the modified example thereof, the formation position of the image line portion GB with respect to the original plate material Wa and the machining position of punching and bending with respect to the printing plate intermediate body Wb have the same predetermined reference or the same. Positioned via one or more surrogate references located from the reference.
As a result, the image line portion forming position and the machining position are positioned from substantially the same reference.
Therefore, the positional relationship between the image line portion GB, the hole Wb1 and the bent portion Wb2 is determined with high accuracy regardless of the individual printing plate, and color misalignment or image line misalignment occurs during multicolor printing. Hateful.

The plate making system 51 of the embodiment will be specifically described as an example. The reference in the front and rear direction in the plate making system 51 is the rear side surface 2f of the table 2, and the reference in the left and right direction is the side surface 2e of the table 2.
In the original plate material Wa, the proxy reference in the front-rear direction of the image portion formation position is the positioning pin 4r2, and the proxy reference in the left-right direction is the positioning pin 2c.
In the printing plate intermediate body Wb after the image line portion GB is formed, the proxy reference in the front-rear direction and the left-right direction of the machining position is maintained by suction, so the positioning pin 4r2 and the positioning pin 2c are applied as they are.
On the other hand, the operation position of the head unit 7 in the image line forming device 52 is set with reference to the rear side surface 2f and the side surface 2e, and the processing positions of the punch unit 11 and the bending unit 12 are also set to the rear side surface 2f and the side surface 2e. Set as standard.
Therefore, the formation of the image line part GB by the image line part forming device 52 in the plate making system 51 and the machining by the processing device 53 are different from each other, and the same standard is used although the printing plate intermediate Wb is conveyed between the devices. Positioned by the system.
Thereby, the positions of the hole Wb1 and the bent portion Wb2 with respect to the formed image line portion GB are determined with high accuracy. The same applies to the plate making system 61.

The predetermined part serving as the same reference is not limited to the above-described side surfaces 2e and 2f, and may be set to another side surface of the table 2 or another member attached to the table 2.
In addition, the surrogate reference is not limited to one, but a second surrogate reference is provided based on the surrogate reference, and the position of the image line portion and the machining position are determined via a plurality of surrogate standards. You may take out.
