  For example, a display board such as a dial of a watch is manufactured by printing a design such as a color or a pattern by octopus printing or screen printing. If inkjet printing is also used for production of display panels, printing that cannot be expressed by octopus printing or screen printing can be performed. However, display boards come in various shapes and designs, and in order to actually print them, a jig for fixing the printed material (printing object) is matched to the shape of each printed material. It is necessary to form the metal one by one. Therefore, inkjet printing is a costly technique.

  In general, when ink-jet printing is performed with a substrate to be placed on a stage, it is difficult to always perform printing at the same position unless the substrate is fixed, and printing may be displaced. In particular, since many timepiece parts such as timepiece dials are small in size, it is necessary to accurately position the substrate to be printed at the time of printing in order to prevent printing misalignment. Although the printing jig of Patent Document 1 is used for an ink jet printer, when considering the use for printing of a watch part, the positional deviation of the printed material placed on the printed material placing means does not occur. In addition, a means for more precisely positioning the substrate to be printed is required. Further, the printing jig of Patent Document 1 may not necessarily be able to flexibly cope with ink jet printing on a variety of shapes and sizes of printed materials.

  Hereinafter, the manufacturing method of a printing jig and printed matter will be described with reference to the drawings. However, it should be understood that the present invention is not limited to the drawings or the embodiments described below.

  In the following, an example in which the substrate is a watch dial (that is, a dial substrate that is printed and becomes a dial) will be mainly described. A timepiece dial is an example of a display board. This printing jig is a jig for inkjet printing that supports a substrate and is installed in an inkjet printer when printing is performed on the substrate. Specifically, the printing jig has a convex portion formed by ink jet printing on a sheet (jig sheet) or a plate (jig plate) on which a substrate is placed. In the printing process of the dial plate using this printing jig, the printed material is placed on the jig sheet or the jig plate, and the printed material is positioned and fixed by the convex portion. A design layer is formed on the substrate.

  1A and 1B are a plan view and a cross-sectional view of the jig plate 1, respectively. The jig plate 1 functions as a tray that supports a jig sheet on which a dial plate that is a printed material is placed, and is installed in the ink jet printer when the dial plate is printed. As an example, the jig plate 1 has a size of about several tens of cm in length and width and a thickness of about several mm. A region denoted by reference numeral 10 covering almost the entire upper surface of the jig plate 1 is a placement surface on which the jig sheet is placed. A large number of ventilation holes 11 for fixing the jig sheet to the jig plate 1 are formed on the mounting surface 10, and around the mounting surface 10 such as the four corners of the jig plate 1. A through hole (not shown) for fixing the jig plate 1 itself is formed. The through-hole 11 is fine, for example, about a few tens of millimeters according to the size of the dial plate that is the printed material so as to cover the plurality of through-holes 11 wherever the printed material is placed on the placement surface 10. It is formed with a pitch.

  FIG. 2 is a plan view of the jig sheet 2. The jig sheet 2 is a sheet-like member that supports a dial plate that is a substrate to be printed and is placed on the placement surface 10 of the jig plate 1 and has a positioning portion 20 for positioning the dial plate. . The jig sheet 2 is positioned with respect to the jig plate 1 by, for example, matching the right angle of the corner to the corner of the mounting surface 10 of the jig plate 1. In the illustrated example, the printing jig includes a jig plate 1 and a jig sheet 2. For this reason, the upper surface of the jig sheet 2 can also be referred to as a placement surface on which the substrate is placed.

  Unlike the illustrated example, the positioning part 20 may be formed directly on the jig plate 1 without using the jig sheet 2 and the dial may be placed on the jig plate 1. In this case, the printing jig is composed only of the jig plate 1. However, by preparing a plurality of jig sheets 2 for one jig plate 1, while printing a dial using one set of the jig plate 1 and the jig sheet 2, Since dials can be prepared side by side on another jig sheet 2, there is an advantage that the manufacturing efficiency is improved. If the jig sheet 2 can be fixed by any method, printing may be performed by installing the jig sheet 2 directly in the ink jet printer without using the jig plate 1. In this case, the printing jig is composed only of a jig sheet.

  A plurality of dials can be placed side by side on the jig sheet 2, and FIG. 2 shows an example in which six positioning portions 20 are formed so that six dials can be placed. ing. The positioning part 20 is composed of bank-like convex parts 30 and 40, which are formed according to the shape and size of the dial placed on the positioning part 20. The shape and size of the positioning part 20 may all be the same or different from each other.

  FIGS. 3A to 3C are views for explaining an enlarged view of the positioning unit 20 and the dial plate 60 and an example of a method for fixing the dial plate 60 to the positioning unit 20.

  The dial plate (dial plate substrate) 60 is, for example, a substantially circular flat plate (disc-shaped) member having a diameter of about several centimeters and a thickness of about several hundred μm. The printing surface and placement surface of the dial 60 may be formed smoothly, a pattern or the like may be formed in an uneven shape, or may be formed in a satin shape. In the example shown in FIG. 3A, the dial plate 60 has six uneven portions on the side surface (side portion), and has a through hole (a central hole 67 for passing the pointer shaft) in the center. Like the inner wall of the center hole 67, the wall portion located inside the dial 60 is also an example of the side portion.

  Hereinafter, these uneven portions are referred to as uneven portions 61 to 66 in order from the position corresponding to 12:00 of the dial 60 in the clockwise direction. In the illustrated example, the uneven portions 61 to 66 are asymmetric with respect to the center of the dial 60. The concave and convex portions 61, 63, 64, and 66 project from the circular outer periphery of the dial 60 in the circumferential direction, the concave and convex portions 62 and 65 project from the circular outer peripheral portion of the dial 60 in the circumferential direction, and A concave portion (a concave portion 65A described later) is provided at the center.

  The bank-like convex part 30 is a convex part that constitutes the positioning part 20 and is three-dimensionally printed in advance by an ink jet printing method so as to rise on the upper surface of the jig sheet 2. The bank-like convex portion 30 is formed on the outer side of the dial 60 so that the dial 60 which is a printing object contacts the side portion of the dial 60 when the dial 60 is placed on the upper surface (placement surface) of the jig sheet 2. It is formed on the upper surface of the jig sheet 2 along the diameter shape. More specifically, the bank-like convex portion 30 has a shape and a size that the dial 60 fits just inside so that the entire outer periphery of the dial 60 can be fixed. 66 has six concavo-convex portions into which each fits. Hereinafter, the concave and convex portions of the bank-shaped convex portion 30 corresponding to the concave and convex portions 61 to 66 are referred to as jig concave and convex portions 31 to 36, respectively.

  In the illustrated example, the bank-like convex portion 30 surrounds the entire circumference of the dial 60 and is in contact with the entire side portion of the dial 60. However, the bank-like convex part 30 does not necessarily need to surround the entire circumference of the dial 60, and may be formed at least at a position in contact with the concavo-convex shape parts 61 to 66 of the dial 60. Alternatively, the bank-like convex portion 30 is at least positioned so that the dial 60 can be positioned and fixed in two directions (XY direction) and a rotation direction (θ direction) perpendicular to each other on the upper surface (mounting surface) of the jig sheet 2. As long as it is formed on the side surface of the dial 60 in contact with two uneven portions (that is, two or more of the uneven portions 61 to 66).

  The bank-like convex part 40 is an example of a second convex part, and constitutes the positioning part 20 together with the bank-like convex part 30. The bank-like convex part 40 is also three-dimensionally printed in advance by the inkjet printing method together with the bank-like convex part 30 so as to rise on the upper surface of the jig sheet 2. The bank-like convex part 40 is formed on the outer peripheral side of the bank-like convex part 30 so as to surround the bank-like convex part 30, has the same shape as the bank-like convex part 30, and is more than the bank-like convex part 30. One size bigger. That is, the bank-like convex portion 40 has jig concave-convex portions 41 to 46 having shapes similar to the jig concave-convex portions 31 to 36 of the bank-like convex portion 30. The bank-like convex portion 40 does not contact the dial plate 60 placed on the jig sheet 2 and does not position and fix the dial plate 60. It is provided as a mark for making the positions of the uneven portions 31 to 36 easy to understand.

  Since the print head moves at high speed in the ink jet printer and wind is generated, if the dial plate 60 is not fixed, the dial plate 60 may move during printing to cause misalignment. For this reason, the printing height (thickness) of the positioning portion 20 (particularly the bank-like convex portion 30) needs to be large enough to fix the dial 60 on the jig sheet 2. However, if the thickness of the positioning portion 20 is too large, it becomes difficult for an operator to attach and remove the dial plate 60. Therefore, the thickness of the positioning portion 20 is an appropriate size that does not impair workability. Is preferred. For these reasons, it is preferable that the thickness of the positioning portion 20 is approximately the same as the thickness of the dial 60.

  As shown in FIGS. 3B and 3C, in order to fix the dial 60 to the positioning portion 20, the concave and convex portions 61 to 66 of the dial 60 are replaced with jig concave and convex portions of the bank-like convex portion 30. It suffices to fit in 31-36. Since the operator only has to place the dial 60 on the jig sheet 2 so as to form a puzzle, the dial 60 can be easily positioned and fixed. In particular, since the bank-like convex part 40 larger than the bank-like convex part 30 is provided as a mark, it is easy for an operator to confirm the positions of the jig uneven parts 31 to 36, and the dial 60 is placed on the jig sheet 2. This improves the accuracy and workability of the work to be placed on. Further, in the illustrated example, since the concave and convex portions 61 to 66 and the jig concave and convex portions 31 to 36 are formed asymmetrically, when the operator tries to place the dial 60 with the front and back reversed, The shape parts 61 to 66 cannot be fitted into the jig uneven parts 31 to 36. For this reason, it is also possible to prevent mistakes in which the operator reverses the front and back of the dial 60.

  The ink jet printer drips ink on the jig sheet 2 and cures it. At this time, since the ink spreads to the surroundings due to the wettability of the ink, the surfaces of the bank-like convex portions 30 and 40 are naturally curved, and the vertical sections of the bank-like convex portions 30 and 40 are rounded. Shape. Since the dial is guided by the curved surface, bank-like convex portions 30 and 40 that are easy to attach and remove the dial naturally are formed by using the ink jet printing method.

  Moreover, since the bank-like convex parts 30 and 40 are formed by inkjet printing, the color can be freely selected. For this reason, if the bank-like convex portions 30 and 40 are formed in a conspicuous color on the jig sheet 2, the positions of the jig concave and convex portions 31 to 36 can be easily understood for the operator, and the dial 60 is placed. Work becomes easier.

  4 (A) to 4 (C) are diagrams for explaining an engaging portion between the dial 60 and the movement of the timepiece. On the side portion of the dial plate 60, a plurality of engaging portions for engaging the dial plate 60 with a watch movement are formed through bosses. In the illustrated example, in the dial 60, the concavo-convex portions 62 and 65 correspond to engaging portions that engage with the movement to which the dial 60 is fixed.

  FIG. 4A is an enlarged view of the concavo-convex shape portion 65. The concave and convex portion 65 is formed with a concave portion 65A for passing a fixing boss. The uneven portion 62 on the opposite side of the uneven portion 65 across the center of the dial 60 also has the same shape as the uneven portion 65. FIG. 4B shows a state in which the dial 60 is fixed to the watch inner frame 81. Although not shown in FIG. 4B, at this time, the movement of the timepiece is disposed under the dial 60, and the dial 60 is fixed to a boss fitted into the concavo-convex portions 62, 65. . FIG. 4C is a partially enlarged view of FIG. 4B, and shows a state in which the boss 82 is fitted in the recess 65 </ b> A of the uneven shape portion 65. Since the boss 82 is formed on the movement or the inner frame 81 that holds the movement, the dial 60 is fixed to the movement via the boss 82.

  Thus, the dial 60 is fixed to the movement at the two portions of the concave and convex portions 62 and 65. On the outer periphery of the dial plate 60, the engagement portion with which the dial plate 60 engages with the movement is strictly dimensionally controlled. Therefore, even the jig sheet 2 has at least the concave and convex portions 62 and 65 that are the engagement portions. May be used for positioning and fixing the dial 60. That is, the bank-like convex portion 30 does not necessarily surround the entire circumference of the dial plate 60 as described above, but at least a plurality of engaging portions (uneven shape portions 62 and 65) of the dial plate 60 respectively. It is preferable that it is formed corresponding to the contact position. In particular, by using each of the plurality of engaging portions for printing positioning, it is more difficult for the printing position shift to occur. The concavo-convex shape portion that is strictly dimension-controlled and serves as the engagement portion is not limited to the concavo-convex shape portions 62 and 65, and may be provided at other positions, for example, at 12 o'clock.

  For example, when making a blue dial by printing a transparent dial, first the blue is printed on the back side of the transparent dial, and further white is printed on it to make the blue clear. After that, the dial is turned over and characters (time characters) are printed on the front side. Thus, in the actual printing process, both sides of the dial plate are often printed. In this case, a front surface jig sheet and a back surface jig sheet are prepared. The jig sheet for the surface has a bank-like convex part in which a jig uneven part is formed at a position that matches the uneven part 61 to 66 when the front surface of the dial 60 is faced up. The jig sheet for the back surface has a bank-like convex part in which a jig uneven part is formed at a position that matches the uneven part 61 to 66 when the back surface of the dial 60 is turned up.

  Although not shown, the jig sheet 2 is given an identification code such as a barcode, and the identification code is associated with information such as the date of manufacture and production conditions of the dial plate 60 to thereby give the jig sheet 2 A traceability function may be provided. In general, the dial 60 is provided with a component code, and the component code may be associated with the identification code of the jig sheet 2.

  Moreover, although the example in case the uneven | corrugated shaped parts 61-66 are the convex parts which protrude from the circular outer peripheral part of the dial 60 was shown above, the uneven | corrugated shaped part was dented from the circular outer peripheral part of the dial 60. The bank-like convex part which has the recessed part of the shape corresponding to a recessed part in the circumferential direction may be sufficient. Even in this case, the dial 60 can be positioned similarly.

  FIGS. 5A and 5B are plan views of different jig sheets 2 ′ and 2 ″, respectively. The positioning portion 20 ′ (bank-like convex portion 30 ′) of the jig sheet 2 ′ shown in FIG. 5A has a notch 37 in a part in the circumferential direction. Like the bank-like convex part 30 ′, the bank-like convex part does not have to surround the entire circumference of the dial 60, and the operator is more likely to have the notch 37 in a place where there is no jig uneven part. It becomes easy to take out the dial 60 from the jig sheet.

  The positioning portion 20 '' of the jig sheet 2 '' shown in FIG. 5B is placed at the placement position of each dial plate 60 and corresponds to the printing applied to the dial plate 60 placed at that position. Printing 13 is performed in advance. Thus, the jig sheet is not necessarily solid. In general, since the shape and size of the dial plate 60 vary depending on the product, in particular, when printing a plurality of dial plates 60 with different colors and designs (printing specifications are different from each other) at a time, It is preferable that the same printing as that of the finished dial 60 is applied to the jig sheet as the base printing 13. In addition, for example, when a plurality of types of dials 60 having different outer diameter shapes or different colors are placed on the jig sheet, the base printing 13 may be similarly applied. . This makes it easy for the operator to know where the dial 60 should be placed, and prevents the operator from making a mistake in placing the dial 60, so that the dial 60 is placed on the jig sheet. This improves the accuracy and workability of the work to be placed on.

  FIG. 6A and FIG. 6B are plan views of another jig sheet 3. Similarly to the jig sheet 2, the jig sheet 3 is a sheet-like member that supports a dial plate that is a printed material and is placed on the placement surface 10 of the jig plate 1. However, the jig sheet 3 is a base printing corresponding to the shape of the positioning portion for positioning the dial and the printing applied to the dial placed at the position at the placement position of each dial. 14 differs from the jig sheet 2 in that 14 is applied in advance. The printing jig may be composed of a jig plate 1 and a jig sheet 3.

  A plurality of dials can be placed side by side on the jig sheet 3, and in FIG. 6A, three positioning parts 50 are formed so that three dials can be placed. An example is shown. Even in the jig sheet 3, the presence of the base printing 14 makes it easy for the operator to know which dial should be placed where, and the accuracy and workability of the work for placing the dial on the jig sheet. Will improve.

  FIG. 6B shows the position of the dial placed on the jig sheet 3 by a broken line without describing the base printing 14 in order to easily show the structure of the positioning portion 50 of the jig sheet 3. It is a thing. The positioning unit 50 includes a central convex portion 51 and an outer peripheral convex portion 52.

  FIGS. 7A to 7E are views for explaining an example of an enlarged view of the positioning unit 50 and the dial plate 70 and a method for fixing the dial plate 70 to the positioning unit 50. FIG.

  The dial plate (dial plate substrate) 70 is, for example, a substantially circular flat plate (disk-shaped) member having a diameter of about several centimeters and a thickness of about several hundred μm. In the example shown in FIG. 7A, the dial plate 70 has six uneven portions on the side surface (side portion), and has a through hole (a central hole 77 for passing the pointer shaft) in the center. Hereinafter, these uneven portions are referred to as uneven shape portions 71 to 76 in order from the position corresponding to 12:00 of the dial 70 in the clockwise direction. In particular, the concavo-convex shape portion 71 is a recess (notch) formed at the 12 o'clock position on the outer periphery of the dial 70, and this recess is a reference for positioning the dial in a conventional octopus printing or screen printing process. Is used and is strictly controlled in dimensions.

  FIG. 7D is an enlarged view of the central convex portion 51. The central convex portion 51 has a hemispherical shape and is formed at a position in contact with the inner wall of the central hole 77 of the dial 70. The positioning portion of the jig sheet is not limited to the side portion on the outer peripheral side of the dial plate, and may be one that contacts the inner wall of the through hole of the dial plate, such as the central convex portion 51. Since the central convex portion 51 is hemispherical, the spherical surface serves as a guide surface, and there is an advantage that the operator can easily attach the dial plate 70 to the jig sheet 3.

  FIG. 7E is an enlarged view of the outer peripheral convex portion 52. The outer peripheral convex part 52 has a triangular columnar shape as an example, and when the dial 70 is placed on the upper surface (mounting surface) of the jig sheet 3, the outer peripheral convex part 52 is formed in the concave part (notch) of the concave-convex shaped part 71. It is formed so as to come into contact with the outer periphery of the dial plate 70 at the place where the concave and convex portion 71 is formed. It is preferable that the printing height (thickness) of the central convex portion 51 and the outer peripheral convex portion 52 constituting the positioning portion 50 is substantially the same as the thickness of the dial 70 as in the positioning portion 20.

  As shown in FIGS. 7B and 7C, in order to fix the dial 70 to the positioning portion 50, the concave and convex portions 71 and the central hole 77 of the dial 70 are respectively formed as the central convex portion 51 and the outer peripheral convex portion. What is necessary is just to insert in the part 52. FIG. Even when the jig sheet 3 is used, the operator only has to place the dial plate 70 on the jig sheet 3 so as to form a puzzle, so that the dial plate 70 can be easily positioned and fixed. Since the positioning part 50 is composed only of the central convex part 51 and the outer peripheral convex part 52, the structure is simpler than the positioning part 20 of the jig sheet 2, and the dial 70 is positioned and fixed with fewer convex parts. Is possible.

  Unlike the jig sheet 2, the jig sheet 3 can be used when printing the front (front) surface of the dial plate and when printing the back surface. Which of the jig sheets 2 and 3 is used can be appropriately selected depending on the outer diameter shape of the dial.

  Instead of the center hole 77, a hole for passing a needle shaft for a small needle, a window hole for calendar display, or the like may be used for positioning the dial 70. In this case, when the dial 70 is placed, it is possible to form a convex portion at a position on the jig sheet 3 that is in contact with the inner walls of these holes, and to position the dial 70 by the convex portion. .

  FIGS. 8A and 8B are plan views of different jig sheets 3 ′ and 3 ″, respectively. The positioning portion 50 ′ of the jig sheet 3 ′ shown in FIG. 8A does not have the central convex portion 51 but has only the outer peripheral convex portion 52. If the dial plate can be reliably positioned and fixed only by the outer peripheral portion depending on the type of ink jet printer used and the type of dial to be printed, the positioning portion does not necessarily have a central convex portion like the positioning portion 50 ′. It does not have to be. Further, the positioning part 50 '' of the jig sheet 3 '' shown in FIG. 8B sandwiches the central convex part 51 in addition to the central convex part 51 and the outer peripheral convex part 52 which are the same as those of the positioning part 50. It has the outer peripheral convex part 53 formed in the opposite side to the outer peripheral convex part 52. FIG. If the dial plate has a plurality of outer peripheral convex portions like the positioning portion 50 ″ and contacts the dial plate at a plurality of points on the outer periphery of the dial plate, the dial plate can be positioned and fixed more reliably.

  Further, instead of the outer peripheral convex portion 52, for example, the outer peripheral convex portion is formed at two locations on the jig sheet 3 that are in contact with the 3 o'clock side and the 9 o'clock side of the concave and convex portion 71 when the dial 70 is placed. May be formed, and the dial 70 may be fixed by sandwiching the concavo-convex shape portion 71 by these outer peripheral convex portions.

  FIG. 9A to FIG. 9E are conceptual diagrams for explaining an example of a printing method for the dial plate 60. Below, with reference to these figures, the example of the manufacturing method of the printed matter (character board) using the jig | tool sheet | seat 2 is demonstrated. The same applies to the case where jig sheets 2 ', 2 ", 3, 3', 3" are used.

  To print the dial plate, the operator first places and positions the jig sheet 2 of FIG. 2 on the jig plate 1 of FIG. 1, as shown in FIG. Is installed in the inkjet printer 100. The ink jet printer 100 is, for example, a UV digital ink jet printer, and expresses a color by a combination of four colors of YMCK and performs color printing.

  Then, as shown in FIG. 9B, the operator operates the ink jet printing machine 100 to position the positioning unit 20 (bank-like shape) on the upper surface (placement surface of the dial plate) of the jig sheet 2 by the ink jet printing method. Convex portions 30, 40) are formed. The bank-like convex portions 30 and 40 are formed by performing multiple printing at the same position on the jig sheet 2. At this time, it is not necessary to print with the same color every time, and printing may be performed with the color only once for the first time and then with the transparent ink for the second and subsequent times. Depending on the viscosity of the ink, three-dimensional printing can be easily realized by using the transparent ink.

  Subsequently, the operator takes out the jig plate 1 and the jig sheet 2 from the ink jet printing machine 100, and moves the dial 60 before printing onto the bank-like projections on the jig sheet 2 as shown in FIG. 9C. The dial 60 is positioned and fixed with the bank-shaped convex portion 30 as a reference by being fitted into the portion 30. At that time, the dial 60 is placed on the upper surface (mounting surface) of the jig sheet 2 such that the concave and convex portions 61 to 66 on the side of the dial 60 are in contact with the jig concave and convex portions 31 to 36 of the bank-like convex portion 30. ).

  Next, as shown in FIG. 9D, the operator places the jig sheet 2 on which the dial plate 60 is placed again on the jig plate 1 and positions the jig sheet 2 on the jig plate 100. Install in. Then, the operator operates the ink jet printing machine 100 to print each dial plate 60 by the ink jet printing method. Thereby, as shown in FIG. 9E, printing of the dial 60 is completed.

  When the positioning portion 20 is directly formed on the jig plate 1 without using the jig sheet 2, the jig sheet 2 of FIG. 2 is placed on the jig plate 1 of FIG. The step of placing and positioning is omitted, and in FIG. 9C, the dial plate 60 before printing is directly placed on the jig plate 1 on which the positioning portion 20 is formed.

  In the step of printing the dial (FIG. 9E), an ink jet printer different from the step of forming the positioning unit 20 (FIG. 9B) may be used, but the positioning unit 20 is formed. It is preferable to use the same ink jet printer 100 as the process. If the same inkjet printer 100 is used in the two steps, the displacement between the positioning unit 20 and the printing on the dial plate is reduced, so that the printing displacement can be suppressed to about 10 μm or less, for example.

  When repeatedly printing a dial having the same printing specifications, the jig sheet 2 on which the positioning portion 20 is formed in the step shown in FIG. 9B can be repeatedly used in the steps after FIG. 9C. . That is, first, the steps of FIGS. 9A and 9B are performed, and thereafter, the steps of FIGS. 9C to 9E can be repeatedly performed.

  The above-described jig sheets 2 and 3 can be easily produced by an ink jet printing method. Moreover, if the jig | tool sheets 2 and 3 etc. are used, the printing of the dial plate which utilized the advantage of the inkjet printing method is possible.

  FIG. 10 is an exploded perspective view of the wristwatch 90. In addition to the dial plate (the dial plate 95), for example, the windshield glass 91, the turning ring 92, the bezel 93 (the windshield) shown in FIG. A ring-shaped part around the glass 91), a pointer (hour hand 94A, minute hand 94B, second hand 94C), a reflector (not shown), a back cover 97, a back cover inner surface sticker 98, a band 99, and the like. The reflecting plate is a semi-transmissive member laid on the lower surface of the dial for the purpose of expressing the metal, and transmits light to the solar cell of the watch arranged on the back surface. If inkjet printing is performed using the above-described printing jig, full-color printing on such a reflector can be easily realized.

  The jig sheets 2, 2 ′, 2 ″, 3, 3 ′, and 3 ″ shown in FIGS. 1 to 8 are formed corresponding to the portions whose dimensions are strictly controlled in the dial plates 60 and 70. The jig uneven portions 32 and 35 or the outer peripheral convex portions 52 and 53 are used for positioning and fixing the dial plates 60 and 70. However, depending on the allowable range of printing misalignment, a jig uneven portion or an outer peripheral convex portion formed corresponding to a side portion of the dial plate that is not strictly dimension-controlled is used for positioning and fixing the dial plates 60 and 70. It is also possible.

  The jig sheets 2, 2 ', 2 ", 3, 3', 3" are made of a material having a weak intermolecular force with respect to the ink used for forming the positioning portions 20, 50, 50 ', 50 ". Alternatively, if the jig plate 1 is formed, the positioning portions 20, 50, 50 ′, and 50 ″ can be peeled off without damaging the mounting surface with a plastic spatula. For example, when the ink contains an acrylic resin, the jig sheet 2, 2 ′, 2 ″, 3, 3 ′, 3 ″ or the jig plate 1 is made of polyacetal resin, aluminum, stainless steel, a cylinder, or the like. What is necessary is just to form with a metal. On the jig sheet 2, 2 ', 2 ", 3, 3', 3" or the jig plate 1 from which the positioning part has been peeled off, another positioning part 20, 50, 50 ', 50 "is formed again. can do. That is, the jig sheets 2, 2 ′, 2 ″, 3, 3 ′, 3 ″ or the jig plate 1 are repeatedly formed by repeatedly forming the positioning portions 20, 50, 50 ′, 50 ″ on them. can do.

  In each of the above embodiments, the case where the display plate is a dial for a watch has been described. However, the jig plate and the jig sheet described above are inkjets of other display plates such as a vehicle instrument. It can also be applied to printing.
