Description

  The present invention relates to a so-called sheet-to-sheet printing technique in which a wiring pattern or the like is printed on a flat plate-like substrate using a flat plate-like intaglio.

  In recent years, attempts have been made to form electrode patterns in devices such as electronic circuit substrates and touch panel substrates by intaglio printing. For example, Patent Documents 1 and 2 describe an intaglio 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-like intaglio is leveled by a doctor blade and the excess ink is scraped to fill the recesses with the ink (filling step). Then, after the ink of the flat plate-like intaglio is received by the transfer means in which the blanket is wound around the blanket cylinder (reception step), the ink on the transfer means is transferred onto the substrate (transfer step).

  In the above-described printing apparatus, after the transfer means receives the ink of the plate-like intaglio, a part of the ink may remain in the concave portion of the plate-like intaglio. When the residual ink is dried, the apparent depth of the depressions in the flat plate-like intaglio becomes shallow, which causes the deterioration of the printing quality from the next time on.

  Here, Patent Document 2 discloses a technique for preventing drying of the ink lower layer portion remaining in the pattern. Patent Document 2 describes a technique of operating the inking mechanism to start inking after the receiving process. As a result, the pattern area where the blanket has already been rolled after the receiving step is inked, so that even if the transfer material is received by the blanket, all the pattern portions of the plate surface are covered with the ink composition. , It will be saved as it is until the next printing.

In the present embodiment, a position adjustment mechanism 65 is provided to move the alignment camera 64 in the X direction, the Y direction, and the Z direction. The position adjusting mechanism 65 drives the support portion 61 supporting the alignment camera 64 in the Y direction with respect to the base 2, thereby driving the drive portion for positioning the alignment camera 64 in the Y direction, and the beam member 63 of the support portion 61. And a drive unit which drives and positions the alignment camera 64 in the X and Z directions. Therefore, the position adjusting mechanism 65 moves the alignment camera 64 in the X direction, the Y direction and the Z direction in response to the operation command from the control unit 90, whereby a part of the work 4 held on the work stage 72 is obtained. It is possible to capture images with high accuracy.

  Further, the alignment camera 67 is attached to the beam member 66 of the other support portion 62 so as to be movable in the X direction and the Z direction. In the present embodiment, a position adjustment mechanism 68 is provided to move the alignment camera 67 in the X direction, the Y direction, and the Z direction.

Therefore, the position adjusting mechanism 65 moves the alignment camera 64 in the X direction, the Y direction and the Z direction according to the operation command from the control unit 90, in the same manner as the alignment camera 64 described above. A portion of the work 4 different from the portion imaged by 64 can be imaged with high accuracy. The two images thus captured are also transferred to the control unit 90 and stored in the memory (symbol 92 in FIG. 4).

  FIG. 4 is a block diagram showing an electrical configuration of the printing apparatus of FIG. The control unit 90 of the printing apparatus 1 stores and saves a CPU 91 which executes a predetermined processing program to control the operation of each part, and a processing program executed by the CPU 91 and data generated during processing. A memory 92 for the purpose, and an operation display unit 93 for notifying the user of the progress of the process, occurrence of abnormality and the like as needed and for receiving input from the user are provided. Then, the CPU 91 controls each part of the apparatus according to the processing program to execute an ink supply process, a full filling process, a receiving process, a transfer process, a temporary filling process, and the like described in detail below. Note that “temporary filling” means that the ink is roughly leveled to such an extent that the ink remains thin on all or part of the upper surface 3 b of the intaglio 3 as described in detail later, and that the recess 3 a is filled with the ink. “Full filling” means that the ink on the upper surface 3 b of the intaglio 3 is scraped off and the recess 3 a is filled with the ink.

5A to 5C schematically show printing operations performed by the printing apparatus shown in FIG. The symbols DP1, RP / TP, IP and DR2 in these figures are respectively
DP1: main filling position where main filling is performed by the doctor blade portion 36,
RP / TP: reception transfer position where reception and transfer are performed by the transfer roller 43,
IP: Ink supply position to which ink is supplied from the slit nozzle 54,
DP2: means a temporary filling position where temporary filling is performed by the doctor blade unit 56. The hatched portion means that the concave portion 3a of the intaglio 3 is fully filled with the ink, while the textured portion indicates that the concave portion 3a of the intaglio 3 is temporarily filled with the ink.

  Here, the printing operation for the first to third sheets will be described in detail on the premise that the printing preparation operation described below has been completed and the printing operation for the first sheet can be started. . In this printing preparation operation, the plate stage unit 10 is positioned at the loading / unloading position for delivering the intaglio 3 to the intaglio supply / recovery device (not shown) by the transport unit 80, and from the intaglio supply / recovery device The intaglio plate 3 carried in is held by the plate stage 12. Further, the work stage unit 70 is positioned at the load / unload position for delivering the work 4 to and from the work supply and recovery device (not shown) by the transport unit 80, and before printing carried from the work supply and recovery device The work 4 is held by the work stage 72. Also, the so-called alignment operation of aligning the work 4 with the intaglio 3 based on the image of the intaglio 3 obtained by the plate alignment unit 20 and the image of the work 4 obtained by the work alignment unit 60 is completed. . Furthermore, as schematically shown in the upper part of FIG. 5A, the doctor blade portions 36 and 56 and the transfer roller 43 are retracted upward from the full filling position, the receiving transfer position and the temporary filling position, respectively.

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

Step S101: Ink Supplying Step The plate stage unit 10 is moved in the Y2 direction and positioned at the ink supply position IP while holding the upper surface 3b of the intaglio 3 in a horizontal posture directed upward. More specifically, as shown in FIG. 5A, when the Y2-direction end of the intaglio 3 reaches the position directly below the discharge port 541 of the slit nozzle 54, the plate stage unit 10 stops moving. Subsequently, the ink is supplied from the ink supply unit 55 to the slit nozzle 54 and discharged onto the upper surface 3 b of the intaglio 3. As a result, the ink reservoir IK is formed at the upper end portion of the intaglio 3 in the Y2 direction side (ink supply step).

Step S102:
The plate stage unit 10 moves in the Y1 direction while supporting the ink reservoir IK on the upper surface 3b of the intaglio 3, and the plate stage unit 10 stops moving when the ink reservoir IK exceeds the full filling position DP1. Following this, the doctor blade portion 36 descends to press the tip 361 (FIG. 3) against the upper surface 3 b of the intaglio 3.

Step S103: First full-filling step The plate stage unit 10 moves in the Y2 direction while the front end 361 of the doctor blade portion 36 abuts on the upper surface 3b of the intaglio 3. At this time, the ink reservoir IK is scraped off by the doctor blade portion 36, and the concave portion 3a is filled with the ink. Here, since the pressing pressure of the doctor blade portion 36 is set relatively strong, the ink does not remain on the upper surface 3b of the intaglio 3 after the doctor blade portion 36 passes, and the ink is filled only in the concave portion 3a. It is done (this filling process). Subsequently, the plate stage unit 10 is moved in the Y2 direction to move the Y2-direction end of the intaglio 3 to the receiving transfer position RP / TP.

Step S104: First sheet receiving process and second sheet temporary filling process The transfer roller 43 descends and is positioned at the reception transfer position RP / TP and the transfer roller 43 rotates clockwise on the sheet of FIG. 5A (step S104) Hereinafter, such rotation is called "forward rotation"). Further, in synchronization with the forward rotation operation, the plate stage unit 10 moves in the Y2 direction through the receiving transfer position RP / TP while holding the intaglio 3 which has been subjected to the main filling process. During this passage, the ink filled in the recess 3a is transferred to the outer peripheral surface of the transfer roller 43 and received (reception step). This receiving process is continued until the intaglio 3 completely passes the receiving transfer position RP / TP.

  By the way, as shown in FIG. 5A, since the distance between the receiving and transferring position RP / TP and the ink supply position IP is shorter than the length of the conveying direction Y of the intaglio 3, the intaglio 3 is The Y2 direction end of the upper surface reaches the ink supply position IP. Therefore, for the second printing operation, the ink supply is performed at the arrival timing, and the ink reservoir IK is formed on the upper surface 3 b of the intaglio 3. As described above, in the present embodiment, the first receiving step and the second ink supplying step are performed in parallel, and in the intaglio 3, the first printing ink and the second printing ink are used. Co-exist.

  Here, in the surface area of the upper surface 3 b of the intaglio 3 which has been subjected to the receiving process, most of the ink is transferred to the transfer roller 43 from the recess 3 a, but some ink may remain on the intaglio 3. If left as it is until the next ink supply, the solvent component in the residual ink may volatilize and adhere to the intaglio 3 in a solid state. If the printing operation is continued using the intaglio 3 to which such dry ink is attached, printing defects may occur. Therefore, in the present embodiment, a so-called temporary filling process in which the ink reservoir IK formed as the second printing ink is roughly evenly distributed over the entire upper surface 3b of the intaglio 3 by the doctor blade 56 positioned at the temporary filling position DP2. Run.

  FIG. 6A is a view showing a temporary filling process. In this temporary filling step, the tip end 561 of the doctor blade 56 is set weaker than the pressing pressure in the above-described full filling with respect to the upper surface 3b of the intaglio 3 moving in the Y2 direction. Therefore, the ink of the ink reservoir IK spreads thinly on the upper surface 3 b of the intaglio 3, whereby the upper surface 3 b of the intaglio 3 is covered with the ink. For this reason, generation | occurrence | production of dry ink can be suppressed effectively and the improvement of printing quality can be aimed at.

  Further, as shown in FIG. 6A, in the area to which the ink reservoir IK is supplied, which is not yet leveled by the tip 561 of the doctor blade 56, the recess 3a of the intaglio 3 is not filled with ink from the ink reservoir IK. . This is due to the high viscosity of the printing material used as the ink and the narrow width (i.e., line width) of the recess 3 a in the X or Y direction. Thus, only by supplying the ink from the slit nozzle 54, the inside of the recess 3a can not be sufficiently filled with the ink, and air exists in the recess 3a, so the solvent component in the ink remaining in the recess 3a However, they volatilize into the air and adhere to the intaglio 3 in a solid state, which may cause printing defects.

  On the other hand, in the first embodiment of the present invention, by disposing the doctor blade portion 56 on the Y2 side of the slit nozzle 54, the ink can be reliably filled in the recess 3a. Thereby, the generation of the dry ink can be effectively suppressed, and the printing quality can be improved.

Step S105:
When the entire intaglio 3 passes the receiving transfer position RP / TP, the receiving process of the first sheet is completed. In response to this, the transfer roller 43 stops its rotation and retracts upward. Subsequently, the entire intaglio 3 passes through the temporary filling position DP2 to complete the temporary filling process for the second printing operation. As a result, the doctor blade 56 retracts upward and the plate stage unit 10 stops moving. At this time, as shown in FIG. 5B, the plate stage unit 10 and the work stage unit 70 are located on the Y2 direction side of the roller unit 40.

Steps S106 to S109: Transfer Step of Second Sheet and Full Filling Step of Second Sheet Next, the first transfer step and the second full filling step of the second sheet are performed in parallel. The plate stage unit 10 moves in the Y1 direction while holding the intaglio 3 which has undergone the temporary filling process, and stops moving when the Y2-direction end of the intaglio 3 reaches the full-filling position DP1. Subsequently, the doctor blade portion 36 descends and the tip 361 is pressed against the upper surface 3b of the intaglio 3 (step S106). This starts the main filling process. Thus, in the present filling step, as shown in FIG. 5B, at the position (corresponding to the “second position” in the present invention) P2 where the center position of the intaglio 3 is separated from the receiving transfer position RP / TP by the distance L2 in the Y1 direction. Starting from the positioned state, the intaglio 3 is further transported in the Y2 direction, and the main filling process proceeds.

  On the other hand, the work stage 72 moves in the Y1 direction while holding the work 4 before printing following the movement of the printing plate stage unit 10 in the Y1 direction, and the Y2 direction side end of the work 4 receives the receiving transfer position RP / TP. Stop moving when you reach. Subsequently, the transfer roller 43 is rotationally positioned so that the leading position of the received ink is located at the lowest lowest point of the outer peripheral surface of the transfer roller 43 and directed to the Y2 direction end of the work 4 It descends and is positioned at the receiving transfer position RP / TP (step S107). Thus, the first transfer process is started. Thus, in the transfer step, as shown in FIG. 5B, the center position of the work 4 is positioned at a position P1 (corresponding to the “first position” of the present invention) separated by the distance L1 in the Y1 direction from the receiving transfer position RP / TP. The transfer process proceeds by the work 4 being further transported in the Y2 direction.

  In the present embodiment, the distance L3 between the receiving transfer position RP / TP and the full filling position DP1 is configured to be longer than the length in the conveyance direction Y of the work 4. Therefore, the steps S106 and S107 are performed in parallel. Of course, the movement mode of the plate stage unit 10 and the work stage unit 70 is not limited to this, and is arbitrary unless the work stage unit 70 collides with the plate stage unit 10.

  When the transfer process is started, the forward rotation operation of transfer roller 43 and the movement operation of work stage unit 70 in the Y2 direction are executed in synchronization, whereby they are received by transfer roller 43 at reception transfer position RP / TP. The transferred ink is sequentially transferred to the work 4. When the entire work 4 passes the reception 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 work 4 (step S108). Thus, the first transfer process is performed, and the first print operation is completed.

  The second main filling step is performed by the doctor blade unit 36 in parallel with the transfer step. FIG. 6B is a view showing a main filling process in the printing operation of the second sheet. The difference between this full filling process and that performed in step S103 is that the temporary filling process has already been performed and the ink has been leveled over the entire upper surface 3b of the intaglio 3, and the other configurations are the same. It is the same. That is, as shown in FIG. 6B, the tip end 361 of the doctor blade portion 36 is set stronger than the pressing pressure at the time of the above-described temporary filling with respect to the upper surface 3b of the intaglio 3 moving in the Y2 direction. Therefore, the ink adhering to the surface area of the upper surface 3b excluding the concave portion 3a is scraped off by the doctor blade portion 36 and the ink disappears from the surface area, whereas the concave portion 3a is filled with the ink.

  In the main filling process, the tip 361 of the doctor blade portion 36 scrapes the ink in the same direction (Y1 direction) as the tip 561 of the doctor blade 56 from the intaglio 3 advancing in the same direction (Y2 direction) as the temporary filling step. . The scraped excess ink is recovered by an ink recovery mechanism (not shown) mounted on the plate stage unit 10, but since both the tip 361 and the tip 561 discharge excess ink to the Y1 direction side of the intaglio 3, One ink recovery mechanism may be provided on the side of the intaglio 3 in the Y1 direction, and the above configuration can suppress an increase in the size of the ink recovery mechanism.

  This full-filling step is continued until the entire intaglio 3 passes through the full-filling position DP1 in the Y2 direction, and during that time, as shown in FIG. 5B, the full-filling region (hatched portion) and the temporary filling region Co-exist with (the satin part). Further, when the entire intaglio 3 passes the full-filling position DP1, the doctor blade portion 36 retracts upward.

Step S110: Preparation for unloading the first printed work 4 When the printing of the pattern PT on the work 4 is completed, the work stage unit 70 moves in the Y2 direction while holding the work 4 to load / unload the work. Move to load position.

Steps S111 and S112: Second Sheet Receiving Step and Third Sheet Ink Supply and Temporary Filling Step In this embodiment, the first sheet which has already been carried on the outer peripheral surface of the transfer roller 43 when the main filling step is completed. The printing ink is transferred to the upper surface 4 a of the work 4. Then, the plate stage unit 10 continues to move in the Y2 direction, and the Y2-direction end of the intaglio 3 reaches the receiving transfer position RP / TP, and the second sheet receiving process is started (step S111). Further, the plate stage unit 10 moves in the Y2 direction in synchronization with the rotation of the transfer roller 43, whereby the ink filled in the recess 3a is transferred to the outer peripheral surface of the transfer roller 43 and received as in step S104. (Step S112). This receiving process is continued until the intaglio 3 completely passes the receiving transfer position RP / TP, and when the receiving process is completed, the transfer roller 43 retracts upward. Subsequently, the entire intaglio 3 passes the temporary filling position DP2 to complete the temporary filling process in the second printing operation. As a result, the doctor blade 56 retracts upward and the plate stage unit 10 stops moving. At this time, the printing plate stage unit 10 and the work stage unit 70 are located on the Y 2 direction side of the roller unit 40.

Steps S113, S114: Replacement of Work Work parallel to performing the second main filling process and the receiving process as described above, for work stage unit 70 waiting at the load / unload position for work A workpiece supply and recovery apparatus (not shown) accesses and replaces the workpiece 4. That is, after the first workpiece 4 on which the pattern PT is printed is carried out of the workpiece stage unit 70 by the workpiece supply and recovery apparatus (step S113), the second workpiece 4 is carried into the workpiece stage unit 70. (Step S114).

After step S115:
After that, printing of the third, fourth,... Can be performed by repeating the same steps as steps S106 to S114 (steps S116 to S123 are illustrated in FIG. 5C). it can. Note that FIG. 5C schematically shows an operation in which the printing operation for the second and third sheets is performed in parallel.

  As described above, in the first embodiment, the main filling step, the receiving step, and the transfer step are performed to print one piece of work 4, but the nth (where n is a natural number of 1 or more) sheet The transfer step for the work 4 and the main filling step for the (n + 1) th intaglio 3 are performed in parallel. For this reason, the tact time of the printing apparatus 1 when printing a plurality of sheets can be shortened by the amount of parallel execution of the transfer step and the main filling step. As a result, the productivity of the printing apparatus 1 can be significantly improved. The above "nth work" and "(n + 1) th work" respectively correspond to the "first base" and the "second base" in the present invention, and for the nth work The printing operation and the printing operation for the (n + 1) th workpiece correspond to the “first printing operation” and the “second printing operation” of the present invention, respectively. These points also apply to the following embodiments.

  Moreover, in the first embodiment, since the temporary filling step is provided, the ink drying on the intaglio 3 can be effectively prevented. As a result, print quality can be improved. In particular, in the temporary filling step, the ink reservoir IK supplied from the slit nozzle 54 is roughly leveled by the tip end 561 of the doctor blade portion 56 to ensure that the ink is filled in the concave portion 3 a of the intaglio 3. Ink drying can be prevented more effectively.

  Furthermore, in the first embodiment, a receiving step from the intaglio 3 for the first work 4 to the transfer roller 43, an ink supplying step to the intaglio 3 for the second work 4, and a temporary filling step In parallel. Thus, by performing the ink supply step and the temporary filling step immediately after the receiving step, the ink drying on the intaglio 3 can be more effectively prevented.

  By the way, in the first embodiment described above, ink is supplied on the Y2 direction side of the roller unit 40, but the ink supply position is not limited to the Y2 direction side, and further on the Y1 direction side of the roller unit 40. An ink supply position may be provided, and ink supply may be additionally performed before the main filling process (second embodiment).

  That is, in the second embodiment, a slit nozzle 34 for ink supply is added to the ink filling unit 30 to function substantially as an ink supply and filling unit. The slit nozzle 34 is disposed adjacent to the doctor blade portion 36 in the Y1 direction. The slit nozzle 34 is the same as the slit nozzle 54 (see FIG. 2) of the first embodiment except that the arrangement position is different. That is, the slit nozzle 34 is a nozzle having a long discharge port 341 extending in the X direction, and is disposed in a state where the discharge port 341 is directed vertically downward. The slit nozzle 34 is connected to the ink supply unit, and discharges the ink supplied from the ink supply unit downward from the ink discharge port 34 to hold the upper surface of the intaglio 3 held by the plate stage unit 10. Form ink reservoir IK on 3b.

  Next, the printing operation of the second embodiment will be described. The second embodiment is different from the first embodiment in that an ink reservoir IK is formed on the Y1 direction side of the doctor blade portion 36 before the main filling step, and the rest performs the same printing operation as the first embodiment. Therefore, the description will be made with reference to FIGS. 5A to 5C, and the description similar to that of the first embodiment will be omitted as appropriate.

Step S101: Full Pre-filling Ink Supply Step The print preparation operation before the printing operation for the first sheet is started is executed as in the first embodiment. Subsequently, the plate stage unit 10 is moved in the Y2 direction while holding the upper surface 3b of the intaglio 3 in a horizontal posture directed upward, and is positioned at the ink supply position located on the Y1 direction side of the full filling position DP1. More specifically, when the Y2-direction end of the intaglio 3 reaches the position immediately below the discharge port 341 of the slit nozzle 34, the plate stage unit 10 stops moving. Subsequently, the ink is supplied from the ink supply unit to the slit nozzle 34 and discharged onto the upper surface 3 b of the intaglio 3. As a result, the ink reservoir IK is formed on the upper end of the intaglio 3 in the Y2 direction side (ink supply process before main filling)

Steps S102 and S103:
While the plate stage unit 10 further moves in the Y2 direction while carrying the ink reservoir IK on the upper surface 3b of the intaglio 3, the doctor blade portion 36 descends to press the tip 361 against the upper surface 3b of the intaglio 3 (step S102). Subsequently, the plate stage unit 10 is further moved in the Y2 direction with the tip 361 of the doctor blade portion 36 in contact with the upper surface 3b of the intaglio 3 (step S103). At this time, the ink reservoir IK is scraped off by the doctor blade portion 36, and the concave portion 3a is filled with the ink. Here, as in the main filling step of the first embodiment, the pressing pressure of the doctor blade portion 36 is set relatively strong, and the ink remains on the upper surface 3b of the intaglio 3 after the doctor blade portion 36 passes. However, the ink is filled only in the concave portion 3a (full filling step). Subsequently, the plate stage unit 10 is moved in the Y2 direction to move the Y2-direction end of the intaglio 3 to the receiving transfer position RP / TP.

Steps S104 and S105:
The first receiving step and the second temporary filling step are performed in the same manner as in the first embodiment.

Step S106:
The plate stage unit 10 moves in the Y1 direction while holding the intaglio 3 from which the ink has been removed in the receiving step, and the ink immediately below the slit nozzle 34 located on the Y1 direction side of DP1 of the intaglio 3 as in step S101. The positioning to the supply position and the formation of the ink reservoir IK from the slit nozzle 34 to the Y2 direction upper surface end of the intaglio 3 which has been temporarily filled is executed. Thus, the ink supply for the second printing operation is executed (step S106).

Steps S107 and S108:
Positioning of the work 4 at the receiving transfer position RP / TP (S107) and printing of the ink pattern PT on the upper surface 4a of the work 4 (S108) are executed as in the first embodiment. Thus, the first transfer process is performed, and the first print operation is completed.

  The second main filling step is performed by the doctor blade unit 36 in parallel with the transfer step. That is, similarly to the first full-filling process (steps S102 and S103), the plate stage unit 10 moves in the Y2 direction while the ink reservoir IK is supported on the upper surface 3b of the intaglio 3, and the doctor blade portion 36 descends. Then, the tip 361 is pressed against the upper surface 3b of the intaglio 3 (step S106). Subsequently, the plate stage unit 10 is further moved in the Y2 direction with the tip 361 of the doctor blade portion 36 in contact with the upper surface 3b of the intaglio 3 (step S109). At this time, the ink reservoir IK is scraped off by the doctor blade portion 36, and the concave portion 3a is filled with the ink. Here, as in the main filling step of the first embodiment, the pressing pressure of the doctor blade portion 36 is set relatively strong, and the ink remains on the upper surface 3b of the intaglio 3 after the doctor blade portion 36 passes. However, the ink is filled only in the concave portion 3a (full filling step). In the present embodiment, the entire intaglio 3 is continued until it passes through the main filling position DP1 in the Y2 direction, and during the continuation, the main filling area (hatched portion) in the intaglio 3 is Y1 of the intaglio 3 as shown in FIG. 5B. It spreads to the direction side end. Further, when the entire intaglio 3 passes the full-filling position DP1, the doctor blade portion 36 retracts upward.

  As described above, in the main filling step in the second embodiment, the ink reservoir IK is further formed from the slit nozzle 34 on the intaglio 3 which has been temporarily filled by the ink supply and filling unit 50 and the doctor blade portion 36 is used. By pressing by this, the concave portion 3a can be reliably filled with the ink.

After step S110:
Step S110 and subsequent steps are performed in the same manner as in the first embodiment except for the third main filling step of steps S116 and S119. In the third full-filling step of steps S116 and S119, an ink reservoir IK is formed by the slit nozzle 34 on the intaglio 3 which has been temporarily filled in the same manner as the second full-filling step (steps S106 and S109). By pressing with the doctor blade portion 36, the concave portion 3a is filled with the ink.

  As described above, in the second embodiment, as in the first embodiment, since the temporary filling step is provided, ink drying on the intaglio 3 can be effectively prevented. As a result, print quality can be improved. In particular, in the temporary filling step, the ink reservoir IK supplied from the slit nozzle 54 is roughly leveled by the tip end 561 of the doctor blade portion 56 to ensure that the ink is filled in the concave portion 3 a of the intaglio 3. Ink drying can be prevented more effectively.

  Furthermore, in the second embodiment, the ink reservoir IK supplied from the slit nozzle 34 in the main filling step is leveled by the tip 361 of the doctor blade portion 36 to ensure that the ink is in the recess 3 a of the intaglio 3. The accuracy of the ink shape transferred from the intaglio 3 to the transfer roller 43 is enhanced. This can improve the print quality.

  The present invention is not limited to the above-described embodiment, and various modifications can be made other than the above without departing from the scope of the invention. For example, in the above embodiment, as shown in FIG. 5B and FIG. 5C, the transfer roller 43 is kept lowered while moving from the n-th transfer step to the (n + 1) -th receive step. When the transfer process is completed, the transfer roller 43 may be retracted upward, and the transfer roller 43 may be lowered to be positioned at the reception transfer position RP / TP when performing the reception process.
