  As a conventional resin embellishment method, a method is known in which a resin heavier is formed on a transparent film by dropping a curable transparent resin on the transparent film (see Patent Document 1).

JP 2008-264275 A

  However, in the conventional resin embellishment method, there is a problem that an operation of attaching a transparent film to an object is necessary in order to form a resin heap.

  Then, an object of this invention is to provide the resin embellishment decoration method which can make the operation | work which forms a resin heap on a target object more efficient than before.

  The resin embellishment method of the present invention is a resin embellishment method for forming a resin heap, which is a decoration made of synthetic resin, on an object, and an ink jet equipped with a recording head that discharges ultraviolet curable ink An image printing step of performing UV inkjet printing of an image on the object by a printer, and a liquid material that is a frame that defines a resin deposit area, which is an area where the resin deposit is formed, and is the basis of the resin deposit A raised frame generating step for generating a raised frame on the object to block the liquid material, and the raised frame generated by the raised frame generating step on the object. A material dripping step of dripping the liquid material into the resin embankment region, and the raised frame generating step is performed by the ink jet printer. Characterized in that it is a step of generating said raised frame by UV inkjet printing.

  With this configuration, the resin embellishment method of the present invention can be achieved by simply performing UV ink jet printing of an image on an object in the work of UV ink jet printing on the object of the work of forming the resin heap on the object. In addition, since the raised frame for blocking the liquid material that is the basis of the resin deposit is also UV inkjet printed on the object, the work of forming the resin deposit on the object can be made more efficient than before.

  Moreover, in the resin embellishment decoration method of this invention, the said protruding frame may form the outline of the said image.

  With this configuration, the resin embellishment method of the present invention drops the liquid material that is the basis of the resin heap onto the resin heap area defined by the raised frame that forms the contour of the image printed on the object. As a result, the resin overlay is superimposed on the image, and as a result, the image can be effectively decorated with the resin deposit.

  In the resin embellishment method of the present invention, at least a part of the raised frame may form at least a part of the image.

  With this configuration, the resin embellishment method according to the present invention is less prominent than the configuration that generates a raised frame that is completely different from the image. Can be decorated.

  Further, in the resin embellishment method of the present invention, at least a part of the main scanning of the recording head when the image is subjected to UV inkjet printing in the image printing step, and the raised frame generation In the step, at least some of the main scans of the recording head in the case of performing UV inkjet printing on the raised frame may be the same main scan.

  With this configuration, the resin embellishment method of the present invention includes a plurality of main scans of the recording head when the image is UV inkjet printed and a plurality of main scans of the recording head when the raised frame is UV inkjet printed. Compared to a configuration with completely separate main scans, the number of main scans of the recording head is reduced as a whole, so that the time required for UV inkjet printing can be reduced, resulting in a resin on the object. The time required for the entire operation of forming the bank can also be reduced.

  In the resin embellishment method of the present invention, the recording head from which the ink for generating the raised frame is ejected in the raised frame generating step is ejected of the ink for generating the image in the image printing step. The recording head may be used.

  With this configuration, the resin embellishment method of the present invention does not require the inkjet printer to be provided with the ultraviolet curable ink dedicated to the raised frame, so the inkjet printer includes the ultraviolet curable ink dedicated to the raised frame. Compared with the configuration, the structure of the inkjet printer to be used can be simplified.

  Also, in the resin embellishment method of the present invention, the ink jet printer is configured so that the recording head for ejecting the ink for the image and the recording head for ejecting the ink for the raised frame are arranged in a sub-scanning direction. A carriage that is shifted and can be moved in the main scanning direction may be provided, and at least a part of the raised frame may overlap the image.

  With this configuration, the resin embellishment method according to the present invention enables the sub-scan to the position at the same time as printing the predetermined position of the image when the decoration in which at least a part of the raised frame overlaps the image is applied. Since the printing of the raised frame is executed at a position shifted in the direction, a plurality of main scans of the recording head when performing UV inkjet printing of an image and a plurality of main scans of the recording head when performing UV inkjet printing of the raised frame Compared with a configuration in which the main scanning is completely separate, the number of main scannings of the recording head can be reduced as a whole. Therefore, the resin embellishment method according to the present invention is capable of completely performing a plurality of main scans of the recording head when performing UV inkjet printing of an image and a plurality of main scans of the recording head when performing UV inkjet printing of a raised frame. Compared to the configuration of separate main scanning, the time required for UV inkjet printing can be reduced, and as a result, the time required for the entire operation of forming a resin pile on the object can also be reduced. .

  The printed matter of the present invention is a liquid material that is a frame that defines an image and a resin heap area that is an area on which a resin heap, which is a decoration made of synthetic resin, is formed. A raised frame raised to block a liquid material is produced by UV inkjet printing.

  With this configuration, the printed matter of the present invention not only performs UV inkjet printing of an image but also blocks the liquid material that is the basis of the resin deposit in the UV inkjet printing operation of the resin deposit forming operation. Since the raised frame is also UV inkjet printed, the work of forming the resin pile can be made more efficient than before. In addition, the printed matter of the present invention can be transferred after the raised frame is generated and before the liquid material that is the basis of the resin deposit is dropped onto the resin deposit region.

  Further, in the printed material of the present invention, the resin bank may be formed in the resin bank region partitioned by the raised frame.

  With this configuration, the printed matter of the present invention not only performs UV inkjet printing of an image but also blocks the liquid material that is the basis of the resin deposit in the UV inkjet printing operation of the resin deposit forming operation. Since the raised frame is also UV inkjet printed, the work of forming the resin pile can be made more efficient than before.

  The resin embellishment decoration method of the present invention can make the work of forming a resin heap on an object more efficient than before.

Guide mechanisms 21a that are movably supported are provided on both sides in the main scanning direction indicated by an arrow 20a.

  The main body 22 includes a guide rail 23 extending in the main scanning direction indicated by an arrow 20a, and a carriage 24 supported by the guide rail 23 so as to be movable in the main scanning direction indicated by an arrow 20a. The carriage 24 irradiates the table 21 with a plurality of recording heads 25 for ejecting UV ink droplets toward the table 21 and ultraviolet rays for curing the UV ink ejected by the recording head 25. An LED (Light Emitting Diode) (not shown) is mounted.

  The recording head 25 is provided for each type of UV ink, such as cyan UV ink, magenta UV ink, yellow UV ink, black UV ink, white UV ink, and colorless and transparent UV ink.

  Next, a resin embellishment method for decorating the object 11 with the resin heap 13, that is, a method for manufacturing the printed material 10 will be described.

1. Printing Step The operator fixes the object 11 at a predetermined position on the table 21 of the ink jet printer 20 and generates the image layer 12 and the raised frame 14 based on the print data on the object 11. To instruct. As the data of the raised frame 14 in the print data, contour data of the image 12a extracted from the image 12a data by image editing software may be employed.

  Upon receiving an instruction from the operator, the inkjet printer 20 moves the carriage 24 with respect to the table 21 along the guide rail 23 in the main scanning direction indicated by the arrow 20a, and moves the main body 22 to the guide mechanism 21a with respect to the table 21. Along the sub-scanning direction indicated by the arrow 20b. That is, the ink jet printer 20 moves the carriage 24 according to the print data with respect to the object 11 fixed on the table 21. The ink jet printer 20 ejects UV ink by the recording head 25 on the carriage 24 toward the object 11 fixed on the table 21, and the carriage toward the UV ink ejected on the object 11. The LED on 24 is irradiated with ultraviolet rays. That is, the inkjet printer 20 performs UV inkjet printing of UV ink on the object 11 in a form based on the print data, so that the image layer 12 made of UV ink and the raised frame 14 made of UV ink are placed on the object 11. Generate.

  FIG. 3A is a front view of a part of the object 11 on which the image layer 12 is generated. FIG. 3B is a bottom cross-sectional view of a part of the object 11 shown in FIG. FIG. 4A is a front view of a part of the object 11 on which the image layer 12 and the raised frame 14 are generated. FIG. 4B is a bottom cross-sectional view of a part of the object 11 shown in FIG.

  In the printing step, after executing the image printing step for generating the image 12a by the image layer 12 on the object 11 as shown in FIG. 3, the raised frame 14 is generated on the object 11 as shown in FIG. The raised frame generation step is performed.

  Here, the raised frame 14 has a thickness larger than the thickness of the image layer 12 in order to define the resin pile region 14 a.

  The difference in thickness between the image layer 12 and the raised frame 14 can be realized by, for example, a difference in the number of UV ink layers ejected by the recording head 25. That is, it can be realized by increasing the number of UV ink layers forming the raised frame 14 to be larger than the number of UV ink layers forming the image layer 12.

  Also, the difference in thickness between the image layer 12 and the raised frame 14 can be realized by, for example, a difference in the size of the UV ink particles ejected by the recording head 25. That is, the particle size at the time when the UV ink forming the raised frame 14 is ejected by the recording head 25 is made larger than the particle size at the time when the UV ink forming the image layer 12 is ejected by the recording head 25. Can be realized.

  The difference in thickness between the image layer 12 and the raised frame 14 is, for example, the difference in the number of UV ink layers ejected by the recording head 25 and the size of the UV ink particles ejected by the recording head 25. It can also be realized in combination with the difference.

There may be at least one. With this configuration, the resin embellishment method according to the present embodiment does not require the inkjet printer 20 to include the UV ink dedicated to the raised frame 14, and therefore the inkjet printer 20 includes the UV ink dedicated to the raised frame 14. Compared with the structure which exists, the structure of the inkjet printer 20 to be used can be simplified.

  The resin embellishment method according to the present embodiment may have a configuration in which the inkjet printer 20 includes UV ink dedicated to the raised frame 14, such as colorless and transparent UV ink or white UV ink.

  FIG. 5A is a front view of a part of the object 11 on which the raised frame 14 is generated. FIG.5 (b) is bottom sectional drawing of a part of the target object 11 shown to Fig.5 (a).

  In the printing step according to the present embodiment, after executing the image printing step for generating the image 12a on the object 11 as shown in FIG. 3, the raised frame 14 is placed on the object 11 as shown in FIG. The generated raised frame generation step is executed. However, in the printing step, an image for generating an image 12a on the object 11 as shown in FIG. 4 after executing the raised frame generation step for generating the raised frame 14 on the object 11 as shown in FIG.

The generated raised frame generation step is executed. However, the printing step simultaneously executes at least a part of the image printing step for generating the image 12a on the object 11 and at least a part of the raised frame generation step for generating the raised frame 14 on the object 11. It may be. For example, as shown in FIG. 6, four main scans of the recording head 25 (see FIG. 2) when the image 12 a is UV inkjet printed in the image printing step, and the raised frame 14 is UV inkjetted in the raised frame generation step. The four main scans of the recording head 25 when printing may be the same main scan. The image layer 12 shown in FIG. 6 is UV-exposed to a quarter of the region at every position in the main scanning direction indicated by the arrow 20a at an arbitrary position in the sub-scanning direction indicated by the arrow 20b (see FIG. 2). The ink particles 15 are landed on the object 11 from the recording head 25, and finally formed in one layer by four main scans. On the other hand, the raised frame 14 shown in FIG. 6 has UV ink particles 15 in the recording head at an arbitrary position in the sub-scanning direction indicated by the arrow 20b in every region in the main scanning direction indicated by the arrow 20a.

The plurality of main scans are all the same main scan. However, when the image 12a is UV inkjet printed in the image printing step, a part of the main scanning of the recording head 25 is performed, and the raised frame 14 is UV inkjet printed in the raised frame generation step. Of the multiple main scans of the recording head 25, some of the main scans may be the same main scan.

  The resin embellishment method according to the present embodiment includes at least a part of main scanning of the plurality of main scannings of the recording head 25 when the image 12a is UV inkjet printed in the image printing step, and a raised frame generation step. In the case where at least some of the main scans of the plurality of main scans of the recording head 25 in the case of UV inkjet printing of the raised frame 14 in FIG. Compared with the configuration in which the main scanning of the recording head 25 is performed separately and the main scanning of the recording head 25 in the case of performing UV inkjet printing on the raised frame 14 are completely separate main scanning, Since the number of times of main scanning is reduced as a whole, the time required for UV ink jet printing can be reduced. The time required for the entire task of forming the overlay 13 can be reduced.

For example, as shown in FIG. 11, the main scanning of the recording head 25 when the image 12a is UV inkjet printed in the image printing step, and the main of the recording head 25 when the raised frame 14 is UV inkjet printed in the protruding frame generation step. The scanning may be the same main scanning. The carriage 24 shown in FIG. 11 has, as the recording head 25, a recording head 25a that discharges UV ink for the image 12a and a recording head 25b that discharges UV ink for the raised frame 14 in the sub-scanning direction indicated by the arrow 20b. It is mounted on the guide rail 23 so as to be movable in the main scanning direction indicated by the arrow 20a. In the resin embellishment method shown in FIG. 11, when a decoration in which the raised frame 14 is overlapped with the image 12 a is given, the sub-scanning direction indicated by the arrow 20 b with respect to this position at the same time as printing the predetermined position of the image 12 a Since the printing of the raised frame 14 is executed at a position shifted to, the plurality of main scans of the recording head 25a when the image 12a is UV inkjet printed, and the plurality of recording heads 25b when the raised frame 14 is UV inkjet printed. Compared with a configuration in which the main scanning of the recording times is completely separate main scanning, the number of main scanning of the recording heads 25a and 25b can be reduced as a whole. Therefore, in the resin embellishment method shown in FIG. 11, the main scanning of the recording head 25a when the image 12a is UV inkjet printed, and the main scanning of the recording head 25b when the raised frame 14 is UV inkjet printed. Compared with a configuration in which scanning is completely separate main scanning, the time required for UV inkjet printing can be reduced, and as a result, it is necessary for the entire operation of forming the resin stack 13 on the object 11. Time can also be reduced.

  FIG. 12 is a front view of a part of the printed material 110 when the raised frame 14 forms a part of the image 12a.

  In the resin embellishment method according to the present embodiment, as shown in FIG. 12, the raised frame 14 may form part of the image 12a. In the resin embellishment decoration method for generating the printed material 110 shown in FIG. 12, the raised frame generation step constitutes a part of the image printing step. With this configuration, the resin embellishment method according to the present embodiment is less prominent than the configuration in which the raised frame 14 that is completely different from the image 12a is generated. The object 11 can be effectively decorated by 13. Note that in the resin embellishment method according to the present embodiment, a part of the raised frame 14 may form a part of the image 12a, or the raised frame 14 that is completely different from the image 12a. May be generated.

  In the resin embellishment method according to the present embodiment, the raised frame 14 forms the contour of the image 12a. With this configuration, the resin embellishment method according to the present embodiment allows the resin heap 13 to be formed in the resin heap area 14 a defined by the raised frame 14 that forms the contour of the image 12 a printed on the object 11. Since the original liquid material is dropped, the resin bank 13 is superimposed on the image 12a. As a result, the image 12a can be effectively decorated by the resin bank 13.

  FIG. 13A is a front view of a part of the printed matter 110 when the raised frame 14 that does not form the outline of the image 12a forms a part of the image 12a. FIG. 13B is a bottom cross-sectional view of a part of the printed material 110 shown in FIG.

  In the resin embellishment method according to the present embodiment, for example, as shown in FIG. 13, the raised frame 14 may not form the contour of the image 12 a. In the resin embellishment method for generating the printed material 110 shown in FIG. 13, the raised frame generation step constitutes a part of the image printing step.

  The printed material 110 is in the state shown in FIG. 10, that is, in a state after the raised frame 14 is generated and before the liquid material that becomes the basis of the resin pile 13 is dropped on the resin pile region 14 a. Can be transferred. When the printed material 110 is transferred in the state shown in FIG. 10, the material dropping step can be executed at the transfer destination.
