Japanese Patent Application No. 2015-221052 (filed on November 11, 2015).

In recent years, the industry has attempted to form an electrode pattern of a device such as an electronic circuit board or a touch panel substrate by gravure printing. For example, Japanese Laid-Open Patent Publication No. 2015-112755 discloses a gravure printing apparatus that performs a filling process, a receiving process, and a transfer process. In this apparatus, the ink supplied to the surface of the flat plate intaglio is leveled by a doctor blade, and excess ink is scraped off and the ink is filled into the concave portion (filling step). Then, after the ink of the flat plate intaglio is received into the transfer device (the receiving process) in which the blanket is wound around the blanket cylinder, the ink on the transfer device is transferred to the object to be printed (transfer process).

In the printing apparatus described above, the printing operation using the same intaglio is repeated a plurality of times. Therefore, in order to ensure excellent production efficiency, it is necessary to shorten the tact time and need The ink is stabilized towards the filling of the intaglio. However, in order to achieve a high degree of print quality, printing accuracy, and the like, the optimum speed of movement is determined by factors such as the ink used, the material of the blanket, and the shape of the pattern. Therefore, it is practically impossible to shorten the tact time of each printing operation in such a manner as to shorten the time required for each process.

Further, in the printing apparatus described above, after the ink of the flat intaglio plate is received into the transfer device, a part of the ink remains in the concave portion of the flat intaglio plate. When the residual ink is dried, the apparent depth of the concave portion of the flat intaglio plate becomes shallow, which causes the printing quality to deteriorate next time.

Here, a technique for preventing the drying of the lower portion of the ink remaining in the pattern is disclosed in Japanese Laid-Open Patent Publication No. 2000-141594. Japanese Laid-Open Patent Publication No. 2000-141594 describes a technique in which an ink application mechanism is operated after receiving a process to start ink application. With this, even if the printing material is received into the blanket by the pattern area in which the blanket of the plate after the acceptance process has been rolled, the pattern portion of the layout is completely covered by the ink composition, and is maintained. Save as it is until the next printing. In other words, in the method disclosed in Japanese Laid-Open Patent Publication No. 2000-141594, after the receiving step, an applicator or a curtain applicator is used as the inking mechanism to prevent drying of the lower portion of the ink remaining in the pattern. However, with the recent miniaturization of the pattern, there is a case where the ink is not supplied to the deep portion of the pattern by the above-described ink-injecting mechanism, and the drying of the lower portion of the ink remaining in the pattern cannot be prevented.

The symbols DP1, RP/TP, IP, and DR2 in the drawings mean the following positions: DP1: the official filling position for the official filling by the blade portion 36; RP/TP: acceptance and transfer by the transfer roller 43 The transfer position is accepted; IP: the ink supply position for supplying ink from the slit nozzle 54; DP2: the temporary filling position for temporary filling by the blade portion 56. Further, the linear hatched portion means that the ink has been officially filled into the concave portion 3a of the intaglio plate 3, and on the other hand, the dotted hatched portion means that the ink has been temporarily filled into the concave portion 3a of the intaglio 3.

Here, the following printing operation will be described in detail, that is, the following printing preparation operation has been completed, and from the first sheet to the third sheet on the premise that the preparation operation of the first sheet can be started. The printing action. This printing preparation operation refers to a loading/unloading position in which the platen unit 10 is positioned by the transfer unit 80 to transfer the intaglio 3 to the gravure supply and collection device (not shown), and the gravure supply and recovery device is carried in. The intaglio 3 is held on the plate stage 12. Moreover, the workpiece stage unit 70 is positioned by the transport unit 80 at the loading/unloading position where the workpiece 4 is transferred between the workpiece supply and collection device (not shown), and the workpiece before being loaded from the workpiece supply and collection device is printed. 4 is held on the workpiece stage 72. Further, the so-called alignment operation of aligning the workpiece 4 with respect to the intaglio 3 based on the image of the intaglio 3 obtained by the plate alignment unit 20 and the image of the workpiece 4 obtained by the workpiece alignment unit 60 is completed. Further, as schematically shown in the upper part of FIG. 5A, the blade portions 36, 56 and the transfer roller 43 are respectively retracted from the official filling position, the acceptance transfer position, and the temporary filling position, respectively.

When the printing operation of the first sheet is started, the steps shown in Figs. 5A to 5C are executed. Hereinafter, the printing operation by the printing apparatus 1 will be described in detail for each step.

Step S101: ink supply process

The plate stage unit 10 puts the upper surface 3b of the intaglio plate 3 in a horizontal posture facing upward. The one side is moved in the Y2 direction and positioned at the ink supply position IP. More specifically, as shown in FIG. 5A, when the end portion on the Y2 direction side of the intaglio 3 reaches the vertical direction of the discharge port 541 of the slit nozzle 54, the plate stage unit 10 stops moving. Then, the ink is supplied from the ink supply portion 55 to the slit nozzle 54, and is ejected to the upper surface 3b of the intaglio 3. Thereby, the ink accumulation portion IK is formed at the upper end portion of the Y2 direction side of the intaglio 3 (ink supply step).

Step S102:

The plate stage unit 10 moves in the Y1 direction while carrying the ink accumulation portion IK on the upper surface 3b of the intaglio plate 3, and stops the movement of the plate stage unit 10 when the ink accumulation portion IK exceeds the official filling position DP1. Then, the blade portion 36 is lowered and the front end 361 (Fig. 3) is pressed against the upper surface 3b of the intaglio 3.

Step S103: the official filling process of the first piece

The plate stage unit 10 is moved in the Y2 direction in a state where the front end 361 abuts against the upper surface 3b of the intaglio 3 before the blade portion 36 is held. At this time, the ink accumulation portion IK is scraped by the blade portion 36 and the ink is filled into the concave portion 3a. Here, since the pressing pressure of the blade portion 36 is set to be relatively strong, the ink does not remain on the upper surface 3b of the intaglio 3 after the blade portion 36 passes, and the ink is only filled into the concave portion 3a (the main filling step). Then, the plate stage unit 10 is moved in the Y2 direction and the Y2 direction side end portion of the intaglio plate 3 is moved to the acceptance transfer position RP/TP.

Step S104: the acceptance process of the first piece and the temporary filling process of the second piece

The transfer roller 43 is lowered and positioned to receive the transfer position RP/TP and the transfer roller 43 is rotated clockwise at the paper surface of FIG. 5A (hereinafter referred to as "forward rotation"). In addition, in synchronization with the forward rotation operation, the plate stage unit 10 moves in the Y2 direction by accepting the transfer position RP/TP while holding the intaglio 3 that has received the main filling process. The ink filled in the concave portion 3a at the time of the passage is transferred to the outer peripheral surface of the transfer cylinder 43, and is accepted (receiving step). This acceptance process continues until the intaglio 3 passes completely through the transfer position RP/TP.

As shown in FIG. 5A, since the distance between the acceptance transfer position RP/TP and the ink supply position IP is shorter than the length of the transfer direction Y of the intaglio 3, the Y2 direction of the upper surface of the intaglio 3 is maintained during the reception process. The side end portion reaches the ink supply position IP. Therefore, in order to perform the printing operation of the second sheet, ink supply is performed at the arrival timing, and the ink accumulation portion IK is formed on the upper surface 3b of the intaglio plate 3. In the present embodiment as described above, the receiving process of the first sheet and the ink supply step of the second sheet are performed in parallel, and the printing ink of the first sheet and the printing ink of the second sheet are stored in the intaglio 3.

Here, although the surface area of the receiving process is received in the upper surface 3b of the intaglio 3, most of the ink is transferred from the concave portion 3a to the transfer roller 43, but a part of the ink remains in the intaglio 3. When the ink supply is left as it is, the solvent component in the residual ink volatilizes and adheres to the intaglio 3 in a solid state. If the intaglio 3 with such a dry ink adhered thereto is used to continue the printing operation, there is a problem that printing defects are caused. Therefore, in the present embodiment, the so-called temporary filling step is performed by using the blade portion 56 positioned at the temporary filling position DP2 to form the ink accumulation portion IK as the printing ink of the second sheet. The surface 3b on the upper surface of the intaglio 3 is roughly flattened as a whole.

Fig. 6A is a view showing a temporary filling process. In the temporary filling step, the front end 561 of the doctor blade portion 56 is set to be weaker than the pressing pressure at the time of the above-described main filling for the upper surface 3b of the intaglio plate 3 that moves in the Y2 direction. Therefore, the ink of the ink accumulation portion IK is thinly spread on the upper surface 3b of the intaglio 3, whereby the upper surface 3b of the intaglio 3 is covered with ink. Therefore, the generation of dry ink can be effectively suppressed, and the printing quality can be improved.

Step S105:

The acceptance process of the first sheet is completed by accepting the transfer position RP/TP as a whole by the intaglio 3 . In response to this, the transfer roller 43 stops rotating and retreats upward. Then, by the gravure 3 as a whole, the temporary filling position DP2 is used for the temporary filling of the printing operation of the second piece. The process is completed. In response to this, the blade portion 56 is retracted to the upper side and the platen unit 10 stops moving. At this time, as shown in FIG. 5B, the plate stage unit 10 and the workpiece stage unit 70 are located at the Y2 direction side of the drum unit 40.

Further, as shown in FIG. 6A, the ink is not filled from the ink accumulation portion IK to the concave portion 3a of the intaglio 3 in the region where the ink portion IK is flattened before the blade portion 56 is flattened. This is because the viscosity of the printing material used as the ink is high, or the width of the concave portion 3a in the X direction or the Y direction (that is, the line width) is narrow. When the ink is supplied from the slit nozzles 54 as described above, since the ink cannot be sufficiently filled into the inside of the concave portion 3a, air is present in the concave portion 3a, so that there is a solvent component remaining in the ink in the concave portion 3a. It is volatilized in the air and adheres to the intaglio 3 in a solid state, which causes a defect in printing.

On the other hand, in the first embodiment, the blade portion 56 is disposed on the Y2 side of the slit nozzle 54, so that the ink can be surely filled in the concave portion 3a. Thereby, the generation of the dry ink can be effectively suppressed, and the printing quality can be improved.

Steps S106 to S109: the transfer process of the first piece and the formal filling process of the second piece

Next, the transfer process of the first sheet and the final filling step of the second sheet are performed in parallel. The plate stage unit 10 moves in the Y1 direction while holding the intaglio plate 3 that has received the temporary filling process, and stops moving when the end portion of the intaglio plate 3 in the Y2 direction side reaches the main filling position DP1. Then, the blade portion 36 is lowered and the front end 361 is pressed against the upper surface 3b of the intaglio 3 (step S106). Thereby, the official filling process begins. As shown in FIG. 5B, the main filling step is positioned at a position away from the accepted transfer position RP/TP from the acceptance transfer position RP/TP by a distance L2 from the accepted transfer position 3 (corresponding to the "second position" of the present invention. In the state of P2, the gravure 3 is transported in the Y2 direction, and the main filling process is continued.

On the other hand, following the movement of the plate stage unit 10 in the Y1 direction, the workpiece stage 72 holds the workpiece 4 before printing and moves in the Y1 direction, and reaches the acceptance transfer position RP at the Y2 direction side end of the workpiece 4. /TP stops moving at the time. Then, the transfer roller 43 is spinning After the positioning is lowered, the position is adjusted to the transfer position RP/TP so that the head position before the ink is received is located at the lowest point of the lowest portion of the outer peripheral surface of the transfer roller 43 toward the Y2 direction side end of the workpiece 4 (step S107). Thereby, the transfer process of the first sheet starts. As shown in FIG. 5B, the transfer process is positioned at a position away from the accepted transfer position RP/TP by a distance L1 from the accepted transfer position RP/TP (corresponding to the "first position" of the present invention. In the state of P1, the transfer process is continued by the workpiece 4 being conveyed in the Y2 direction.

Further, the present embodiment is configured such that the distance L3 between the accepted transfer position RP/TP and the official filling position DP1 is longer than the length of the transport direction Y of the concave workpiece 4. Therefore, the above steps S106 and S107 are performed in parallel. Needless to say, the movement state of the plate stage unit 10 and the workpiece stage unit 70 is not limited thereto, and may be any as long as the workpiece stage unit 70 and the plate stage unit 10 do not collide.

When the transfer process is started, the forward rotation operation of the transfer roller 43 is performed in synchronization with the movement operation of the workpiece stage unit 70 in the Y2 direction, whereby the transfer roller is accepted at the transfer position RP/TP. The ink of 43 is sequentially transferred to the workpiece 4. When the entire workpiece 4 passes the transfer position RP/TP, the ink pattern PT defined by the concave portion 3a of the intaglio 3 is printed on the upper surface 4a of the workpiece 4 (step S108). The transfer process of the first sheet is performed in this manner, and the printing operation of the first sheet is completed.

The main filling step of the second sheet is performed in parallel with the above-described transfer step by the doctor blade portion 36. Fig. 6B is a view showing a formal filling step of the printing operation of the second sheet. The fact that the main filling step differs from the content executed in step S103 is that only the temporary filling step has been performed, and the ink is flattened on the entire upper surface 3b of the intaglio 3, and the other configuration is the same. That is, as shown in Fig. 6B, the front end 361 of the doctor blade portion 36 is set to be stronger than the above-described pressing at the time of temporary filling, with respect to the upper surface 3b of the intaglio plate 3 which is moved in the Y2 direction. Therefore, the ink adhering to the surface region other than the concave portion 3a of the upper surface 3b is scraped by the blade portion 36, and the ink disappears from the surface region, and the ink is filled at the concave portion 3a.

In the main filling step, the front end 361 of the blade portion 36 scrapes ink from the intaglio 3 that travels in the same direction (Y2 direction) as the temporary filling step, in the same direction (Y1 direction) as the front end 561 of the blade portion 56. . The excess ink that has been scraped off is recovered by the ink recovery mechanism that is omitted from the illustration of the platen unit 10, and any of the front end 361 and the front end 561 discharges excess ink toward the Y1 direction side of the intaglio 3. It is only necessary to provide one ink recovery mechanism in the Y1 direction side of the intaglio plate 3. Therefore, by adopting the above configuration, it is possible to suppress an increase in size of the ink recovery mechanism.

This official filling process continues until the entire gravure 3 passes through the official filling position DP1 in the Y2 direction. In the continuous process, as shown in FIG. 5B, the official filling region (linear shading portion) and the temporary portion are present in the intaglio 3 Sex filling area (dotted shadow). Further, when the entire intaglio plate 3 passes through the main filling position DP1, the blade portion 36 is retracted upward.

Step S110: preparation for unloading the workpiece 4 after the first sheet is printed

When the printing of the pattern PT of the workpiece 4 is completed, the workpiece stage unit 70 moves in the Y2 direction while holding the workpiece 4, and moves to the loading/unloading position for the workpiece.

Steps S111 and S112: the acceptance process of the second sheet and the ink supply and temporary filling process of the third sheet

In the present embodiment, at the time of completion of the main filling process, the printing ink of the first sheet held on the outer peripheral surface of the transfer cylinder 43 has been transferred to the upper surface 4a of the workpiece 4. Therefore, the plate stage unit 10 continues to move in the Y2 direction as it is, and the Y2 direction side end portion of the intaglio 3 reaches the acceptance transfer position RP/TP, and the acceptance process of the second sheet is started (step S111). Further, the platen unit 10 is moved in the Y2 direction in synchronization with the rotation of the transfer roller 43, and the ink filled in the concave portion 3a is transferred onto the outer peripheral surface of the transfer roller 43 in the same manner as in the above-described step S104, and is accepted. (Step S112). This acceptance process continues until the intaglio plate 3 has completely passed the acceptance of the transfer position RP/TP. When the acceptance process is completed, the transfer roller 43 is retracted upward. Then, by the entire intaglio 3 passing through the temporary filling position DP2, the temporary filling process of the printing operation of the second sheet is completed. In response to this, the blade portion 56 retreats to the top and the plate carrier Unit 10 stops moving. At this time, the plate stage unit 10 and the workpiece stage unit 70 are located at the Y2 direction side of the drum unit 40.

Steps S113, S114: replacement of the workpiece

As described above, in parallel with the main filling step and the receiving step of the second sheet, the workpiece supply unit (not shown) approaches the workpiece stage unit 70 that is placed at the loading/unloading position for the workpiece, and the workpiece 4 is replaced. In other words, the first workpiece 4 on which the pattern PT is printed is carried out from the workpiece stage unit 70 by the workpiece supply and collection device (step S113), and the workpiece 4 of the second sheet is loaded into the workpiece stage unit 70 (step S114). .

After step S115:

After the above steps, the printing of the third, fourth, ... can be performed by repeating the same steps as steps S106 to S114 (steps S116 to S123 are shown in FIG. 5C). In addition, FIG. 5C schematically illustrates an operation in which the printing operation of the second sheet and the third sheet is performed in parallel.

As described above, in the first embodiment, the main filling process, the receiving process, and the transfer process are performed in order to print one workpiece 4, but the nth (where n is a natural number of 1 or more) piece workpiece 4 The transfer process is performed in parallel with the formal filling process of the intaglio 3 of the (n+1)th sheet. Therefore, the tact time of the printing apparatus 1 at the time of printing a plurality of sheets is shortened correspondingly to the execution of the transfer process in parallel with the main filling process. As a result, the production efficiency of the printing apparatus 1 can be greatly improved. Further, the "nth workpiece" and the "nth (n+1)th workpiece" correspond to the "first substrate" and the "second substrate" of the present invention, respectively, and the printing operation and the pair of the nth workpiece are performed. The printing operation of the (n+1)th workpiece corresponds to the "first printing operation" and the "second printing operation" of the present invention, respectively. Further, the ink corresponds to an example of the "printing material" of the present invention, and the workpiece 4 corresponds to an example of the "substrate" of the present invention. Further, the plate stage 12 and the workpiece stage 72 correspond to an example of the "gravure holding portion" and the "substrate holding portion" of the present invention, respectively. Further, the knives 362 and 562 correspond to an example of the "first knife" and the "second knife" of the present invention, respectively. Further, the transfer roller 43 corresponds to one of the "transfer portions" of the present invention. example. In addition, since the transfer stage 83 is moved by the transfer stage 82 of the support plate stage unit 10 and the intaglio plate 3 is transported, the linear drive unit 82 and the transfer stage 83 are used as the "gravure transfer unit" of the present invention. Play the function. Further, since the transfer stage 84 supporting the workpiece stage unit 70 is moved by the linear drive unit 82 to transport the workpiece (base material) 4, the linear drive unit 82 and the transfer stage 84 are used as the basis of the present invention. The material conveyance unit is functional. Further, the control unit 90 corresponds to an example of the "control unit" of the present invention. Further, the direction Y1 and the direction Y2 correspond to the "first direction" and the "second direction" of the present invention, respectively. The same is true for the above embodiments in the following embodiments.

Further, since the temporary filling step is provided in the first embodiment described above, it is possible to effectively prevent the ink in the intaglio 3 from drying. As a result, the printing quality can be improved. In particular, in the temporary filling process, the ink accumulation portion IK of the ink supplied from the slit nozzle 54 is roughly flattened by the front end 561 of the blade portion 56, so that the ink can be surely filled into the concave portion of the intaglio 3. Within 3a, the drying of the ink at the intaglio 3 can be more effectively prevented.

Further, in the first embodiment described above, the accepting step of the n-th sheet is performed in parallel with the temporary filling step of the intaglio 3 of the (n+1)th sheet. Therefore, by executing the acceptance process in parallel with the temporary filling process, the tact time can be shortened as compared with the case where the acceptance process of the nth piece is sequentially performed and the temporary filling process of the (n+1)th piece is performed. Further, by performing the ink supply step and the temporary filling step immediately after the receiving step, the ink in the intaglio 3 can be more effectively prevented from drying to stabilize the filling of the ink of the intaglio 3, and the filling can be greatly improved. The production efficiency of the printing apparatus 1 is improved. In the first embodiment as described above, the slit nozzle 54 corresponds to an example of the "supply portion" of the present invention. Further, the blade portion 36 functions as a "filling portion" and a "main filling portion" of the present invention, and the blade portion 56 serves as a "filling portion" and a "temporary filling portion" of the present invention. function.

In the first embodiment, the ink supply is performed on the Y2 direction side of the drum unit 40. However, the ink supply position is not limited thereto, and may be performed on the Y1 direction side of the drum unit 40 (second embodiment). In addition, it is also possible to enter the Y1 direction of the drum unit 40. The ink supply position is set in one step, and the ink supply is additionally performed before the main filling process (third embodiment). Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. 7A to 7C. Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 5A to 5C and FIG.

7A to 7C are views showing a second embodiment of the printing apparatus of the present invention. The second embodiment differs greatly from the first embodiment in that the ink supply unit 30 is additionally provided with the slit nozzle 34 for ink supply, and functions substantially as an ink supply and filling unit, and the ink supply filling is omitted. At this point, the unit 50 omits the point of the temporary filling process. The other configurations are basically the same as those in the first embodiment, and the same configurations are denoted by the same reference numerals, and the description of the components is omitted.

In the second embodiment, as shown in the upper portion of FIG. 7A, slit nozzles 34 are disposed adjacent to the Y1 direction side of the blade portion 36. The slit nozzles 34 are the same as the slit nozzles 54 of the first embodiment except that they are different from each other in the arrangement position. In other words, the slit nozzle 34 has a nozzle having a long discharge port 341 extending in the X direction, and the discharge port 341 is disposed in a state of being vertically downward. Further, the slit nozzle 34 is connected to an ink supply unit (not shown), and the ink supplied from the ink supply unit is discharged downward from the ink discharge port 341 to the lower surface of the intaglio plate 3 held by the platen unit 10. 3b forms an ink accumulation portion IK.

Next, the printing operation of the second embodiment will be described in detail with reference to FIGS. 7A to 7C. Here, the printing operation described below is described in detail, that is, in the same manner as in the first embodiment, the printing preparation operation has been completed, and the preparation is completed in the state in which the printing operation of the first sheet can be started. The printing operation up to the third piece.

When the printing operation of the first sheet is started, the steps shown in Figs. 7A to 7C are executed. Hereinafter, the printing operation by the printing apparatus 1 will be described in detail for each step.

Step S201: ink supply process

The plate stage unit 10 puts the upper surface 3b of the intaglio plate 3 in a horizontal posture facing upward. The one side is moved in the Y2 direction and positioned at the ink supply position IP. More specifically, as shown in FIG. 7A, when the end portion on the Y2 direction side of the intaglio 3 reaches the vertical direction of the discharge port 341 of the slit nozzle 34, the plate stage unit 10 stops moving. Then, the ink is supplied from the ink supply portion (not shown) to the slit nozzle 34, and is ejected to the upper surface 3b of the intaglio 3. Thereby, the ink accumulation portion IK is formed at the upper end portion of the Y2 direction side of the intaglio plate 3.

Steps S202 and S203: the official filling process of the first piece

The plate stage unit 10 moves further in the Y2 direction while carrying the ink accumulation portion IK on the upper surface 3b of the intaglio plate 3, and the blade portion 36 is lowered to press the tip end 361 against the upper surface 3b of the intaglio plate 3 (step S202). Then, in a state where the front end 361 abuts against the upper surface 3b of the intaglio 3 before the blade portion 36 is held, the platen unit 10 is further moved in the Y2 direction (step S203). At this time, the ink accumulation portion IK is scraped by the blade portion 36 and the ink is filled into the concave portion 3a. Here, similarly to the main filling step of the first embodiment, the pressing force of the blade portion 36 is set to be relatively strong, and after the blade portion 36 passes, the ink does not remain on the upper surface 3b of the intaglio 3, and the ink is only filled. To the recess 3a (formal filling step). Then, the plate stage unit 10 is moved in the Y2 direction and the Y2 direction side end portion of the intaglio plate 3 is moved to the acceptance transfer position RP/TP.

Step S204: the acceptance process of the first piece

The transfer roller 43 is lowered and positioned to receive the transfer position RP/TP and the transfer roller 43 is rotated in the forward direction. In addition, in synchronization with the forward rotation operation, the plate stage unit 10 moves in the Y2 direction by accepting the transfer position RP/TP while holding the intaglio plate 3 that has received the main filling process. The ink filled in the concave portion 3a at the time of the passage is transferred to the outer peripheral surface of the transfer cylinder 43, and is accepted (receiving step).

Step S205:

The above-described receiving process continues until the intaglio plate 3 has completely passed the transfer position RP/TP. At the time of passing, the forward rotation of the transfer roller 43 is stopped and the transfer roller 43 is retracted upward. Further, the movement of the plate stage unit 10 in the Y2 direction is stopped.

Steps S206 to S211: the transfer process of the first piece and the formal filling process of the second piece

The plate stage unit 10 moves in the Y1 direction while holding the intaglio 3 in which the ink is removed by the above-described receiving process, and performs positioning of the intaglio 3 with respect to the ink supply position IP and Y2 in the intaglio 3 as in step S201. The ink accumulation portion IK is formed at the end portion of the direction side upper surface. In this manner, ink supply for the printing operation of the second sheet is performed (step S206).

On the other hand, following the movement of the plate stage unit 10 in the Y1 direction, the workpiece stage 72 holds the workpiece 4 before printing and moves in the Y1 direction, and reaches the acceptance transfer position RP at the Y2 direction side end of the workpiece 4. At the time of /TP, the movement is stopped (step S207). Then, the transfer roller 43 is lowered after the rotational positioning, and is positioned at the acceptance transfer position RP/TP so that the head position of the accepted ink is located at the lowest point of the lowest outer peripheral surface of the transfer roller 43 toward the workpiece 4 Y2 direction side end. Thereby, the transfer process of the first sheet starts.

In the same manner as the step S108 of the first embodiment, the forward rotation operation of the transfer roller 43 is performed in synchronization with the movement operation of the workpiece stage unit 70 in the Y2 direction, thereby receiving the same. The ink received into the transfer roller 43 at the transfer position RP/TP is sequentially transferred to the workpiece 4 (step S208). When the entire workpiece 4 passes the transfer position RP/TP, the ink pattern PT defined by the concave portion 3a of the intaglio 3 is printed on the upper surface 4a of the workpiece 4 (step S209). The transfer process of the first sheet is performed in this manner, and the printing operation of the first sheet is completed.

In parallel with the above-described transfer process, the main filling step of the second sheet is performed by the blade portion 36. In other words, the plate stage unit 10 moves in the Y2 direction while carrying the ink accumulation portion IK on the upper surface 3b of the intaglio 3, and the blade portion 36 is the same as the main filling step of the first sheet (steps S202 and S203). The front end 361 is pressed against the upper surface 3b of the intaglio 3 (step S210). Then, the plate stage unit 10 is further moved in the Y2 direction in a state where the front end 361 abuts against the upper surface 3b of the intaglio 3 before the blade portion 36 is held (step S211). At this time, the ink accumulation portion IK is scraped by the blade portion 36 and the ink is filled into the concave portion 3a. Here, in the same manner as the main filling step of the first embodiment, the pressing force of the blade portion 36 is set. To be relatively strong, the ink does not remain on the upper surface 3b of the intaglio 3 after the blade portion 36 passes, and the ink is only filled into the concave portion 3a (formal filling step). In the present embodiment, the main filling step continues until the entire intaglio 3 passes through the official filling position DP1 in the Y2 direction, and in the continuous process, as shown in FIG. 7B, the area is filled in the intaglio 3 (linear shading portion). The end portion of the intaglio 3 in the Y1 direction side gradually expands. Further, when the entire intaglio plate 3 passes through the main filling position DP1, the blade portion 36 is retracted upward.

Step S212: preparation for unloading of the workpiece 4 after the first sheet is printed

When the printing of the pattern PT of the workpiece 4 is completed, the workpiece stage unit 70 moves in the Y2 direction while holding the workpiece 4, and moves to the loading/unloading position for the workpiece.

Steps S213 and S214: the acceptance process of the second piece

In the present embodiment, at the time of completion of the main filling process, the printing ink of the first sheet held on the outer peripheral surface of the transfer cylinder 43 has been transferred to the upper surface 4a of the workpiece 4. Therefore, the plate stage unit 10 continues to move in the Y2 direction as it is, and the Y2 direction side end portion of the intaglio 3 reaches the acceptance transfer position RP/TP, and the acceptance process of the second sheet is started (step S213). Further, the plate stage unit 10 moves in the Y2 direction in synchronization with the rotation of the transfer roller 43, and the ink filled in the concave portion 3a is transferred to the outer peripheral surface of the transfer roller 43 in the same manner as in the above-described step S104, and is Accepted (step S214). This acceptance process continues until the intaglio plate 3 has completely passed the transfer position RP/TP. When the acceptance process is completed, the transfer roller 43 is retracted upward.

Steps S215, S216:

As described above, in parallel with the main filling process and the receiving process of the second sheet, the workpiece supply and collection device (not shown) is approached to the workpiece stage unit 70 that is standby at the loading/unloading position for the workpiece, and the workpiece 4 is replaced. In other words, the first workpiece 4 on which the pattern PT is printed is carried out from the workpiece stage unit 70 by the workpiece supply and collection device (step S215), and then the second workpiece 4 is carried into the workpiece stage unit 70 (step S216). .

After step S217:

After the above steps, the printing of the third, fourth, ... can be performed by repeating the same steps as steps S206 to S216 (steps S217 to S226 are shown in FIG. 7C). In addition, FIG. 7C schematically illustrates an operation in which the printing operation of the second sheet and the third sheet is performed in parallel.

As described above, in the second embodiment, the main filling process, the receiving process, and the transfer process are performed in order to print one workpiece 4, but the transfer process and the pair (n+1) of the n-th workpiece 4 are performed.
