JP 2000-190462 A

However, the above methods (1) to (5) have the following problems.
(A) In the case of using a single sheet (vinyl chloride, olefin, PET, etc.) that has been subjected to multicolor printing by gravure printing, an expensive plate precursor is manufactured, and after color correction and printing, For pasting, it took a very long lead time (several months) and cost (million yen per plate) until the end of printing (for example, (2) above).
(B) When sticking a sheet, the freedom of three-dimensional shape design of a member becomes low on the restrictions that a sheet is stuck (for example, (1) and (2) above).
(C) The unit pattern lacks a sense of unity (for example, (3) above).
(D) When patterning a member having a curved surface, the pattern of the curved surface portion extends and the value as decoration is reduced (for example, (1), (2), (4), (5) above).
(E) In direct printing by the gravure coater as in (4) above, only single color or two colors can be printed, and it is difficult to pattern various patterns, even simple patterns. Even so, it is difficult to reproduce the color, and it is difficult to make a pattern faithful to the original image.
(F) When the member has a cubic curved surface, it is difficult to affix the sheet to the cubic curved surface, and even if the sheet can be affixed, the pattern is distorted or an unnatural pattern is formed (for example, the above (1) ), (2)).

  The present invention has been made in view of the above-described problems, and provides a printing system and printing method for a member that can reduce the time required to print a pattern on a member and reduce the cost required for printing. This is the first purpose. It is a second object of the present invention to provide a printing system and printing method for a member that can easily print a pattern having a sense of unity on the member.

  The present invention has been made to solve the above-described problems, and the invention according to claim 1 is directed to the member including a first surface having a pattern and a second surface which is a printing surface. A printing system for a member that prints a pattern on a second surface, the data generating device generating image data based on the pattern on the first surface, and the image data generated by the data generating device, A data processing device for processing based on shape data indicating the shape of the member, and a printing device for injecting a printing material onto the second surface of the member based on the image data processed by the data processing device; It is a printing system of the member characterized by comprising.

  Invention of Claim 2 is the printing method of the member which prints a pattern on the said 2nd surface of the member which comprises the 1st surface which gave the pattern, and the 2nd surface which is a to-be-printed surface, , Generating image data based on the pattern of the first surface, processing the generated image data based on shape data indicating the shape of the member, and based on the processed image data And a step of injecting a printing material onto the second surface of the member.

  According to the present invention, since the pattern is printed on the member based on the digital image data, the cost and time for producing the sample plate can be reduced, and the member can be reduced in a short time and at a low cost. The pattern can be printed on Also, digital image data is generated from the pattern of the member, and the pattern based on the digital image data is printed on the unpatterned part of the same member. There is also an effect that it is possible to easily give the printed part a sense of unity with the pattern.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a printing system according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a data processing apparatus for processing image data. The data processing apparatus 1 includes a display unit and an operation unit (not shown), and processes image data according to a processing instruction by a user operation. Further, the data processing apparatus 1 performs processing such as rotation, enlargement, reduction, inversion and the like on the image data when processing the image data. Reference numeral 2 denotes a data generation apparatus, which captures an image from a portion on which a member pattern serving as an image sample is provided and outputs member pattern data 101. The data generation device 2 is realized by a scanner, a digital camera, or the like. The member pattern data 101 is input from the data generation device 2 to the data processing device 1 via a cable or the like.

  The data processing apparatus 1 processes the member pattern data 101. The data processing apparatus 1 takes in member shape data 100 indicating the shape of a member to be printed, and processes the member pattern data 101 based on the member shape data 100. The member shape data 100 is data indicating the shape of a member when the shape of the member is designed by CAD (Computer Aided Design) software. The member shape data 100 may be generated by three-dimensionally scanning or measuring the member.

  The data processing apparatus 1 processes the member pattern data 101 and outputs it as processed digital data 102. A master controller 3 controls printing. The master controller 3 is realized by a general-purpose personal computer or the like. The processed digital data 102 is input to the master controller 3 via a network connection such as a local area network or via a recording medium (flexible disk, CD-ROM, etc.) for recording the processed digital data 102. Note that the master controller 3 may have the function of the data processing device 1.

  The master controller 3 controls the RGB color jet printer 4 based on the input from the user. The master controller 3 receives a print instruction from the user and outputs the processed digital data 102 to the RGB color jet printer 4. The RGB color jet printer 4 is an ink jet printer for thick materials such as wood, and ejects ink (printing material) from a print head (not shown) based on the processed digital data 102 output from the master controller 3. A pattern is printed on the printing surface of the member.

  Instead of the RGB color jet printer 4, a printer that uses a thermal head, a wire dot head, or the like as the print head may be used. The data processing apparatus 1 and the master controller 3 may be general-purpose personal computers. Alternatively, the member digital data 102 may be used without printing the member pattern data 101 and the member may be printed. In that case, the data processing apparatus 1 is not necessary.

  Next, a printing procedure according to the present embodiment will be described with reference to FIG. In the present embodiment, image data is generated from a portion having a pattern for a member including an unpatterned portion, and an unpatterned portion is generated by an RGB color jet printer based on the image data. Perform patterning. The following is the procedure. First, pre-processing is performed on a portion having no pattern in the member so as to facilitate printing (step S200).

  Subsequently, the data generation device 2 captures a pattern from a portion of the member having a pattern and generates image data (step S201). The data processing apparatus 1 takes in the image data and processes the image data so as to be data suitable for a member to be patterned. At this time, the data processing apparatus 1 has the member shape data 100 in advance, processes the image data based on the shape of the member indicated by the member shape data 100, and generates the processed digital data 102. The data processing apparatus 1 also performs image rotation, enlargement, reduction, vertical / horizontal scaling (enlargement / reduction by setting the vertical / horizontal ratio), inversion, and color tone control of the image data. The processed digital data 102 is generated by performing brightness control or the like (step S202).

  Subsequently, the master controller 3 takes in the processed digital data 102 matched with the shape of the member by the processing of the image data in step S202, and receives the processed digital data 102 when receiving a print instruction from the user. Output to 4. The RGB color jet printer 4 prints a pattern on the printing surface of the member based on the processing digital data 102 input from the master controller 3 (step S203).

  Subsequently, a paint finish is performed on the member printed by the RGB color jet printer 4 (step S204). In the above procedure, the paint finish in step S200 may be omitted. In addition, as the paint finish, any paint finish such as a specular gloss finish or a matte finish may be performed, and the paint finish may be omitted.

Next, a first embodiment of the present invention will be described. The following is the processing procedure in the first embodiment. FIG. 3 is a schematic diagram of members for explaining the following processing, and this will be referred to as appropriate.
(1) A polyester decorative board in which a wood grain pattern was printed in advance on an MDF (Medium Density Fiber board) material was attached to both sides of the member with an adhesive.
(2) A part of the member was cut using an NC router in order to obtain a brace shape. The member after cutting was as shown in FIG. Since this part was a cubic surface, when patterning, conventional patterning by hot stamping, vacuum bonding of patterned decorative sheets such as vinyl chloride sheets, olefin sheets, and patterned polyester decorative plywood and dup It was difficult to perform patterning by combining with a sheet or the like.
(3) The portion where the pattern disappeared due to the cutting was polished with sandpaper, and the pretreatment resin was applied with a brush so as to be 30 g / m ² .

(4) After drying, the portion coated with resin was polished with P240 sandpaper.
(5) The pattern portion of the polyester decorative board was photographed with a digital camera (FIG. 3B), and the image data generated thereby was processed so as to match the shape of the cut portion.
(6) Using an RGB color jet printer, a pattern based on the image data generated in (5) was printed on the portion processed in (4) (FIG. 3C).
(7) In order to protect the part where the pattern was applied and give the part a glossy feeling, a polyester coating finish was applied so that the total film thickness was 400 μm (FIG. 3D). Finally, the surface was polished with P800 sandpaper, and then polished by buffing.

  In the member completed by the above processing (arms of the electronic keyboard instrument), there is a sense of unity between the part where the pattern was originally attached and the part where the pattern was printed. The result is a natural and wonderful finish. In addition, you may perform imaging | photography of the pattern part in said (5) using the polyester decorative plywood before sticking on MDF.

Next, a second embodiment of the present invention will be described. The processing procedure is as follows.
(1) An American walnut of a natural decorative board having a thickness of 0.5 mm was pasted on both sides of the MDF material.
(2) The portion where the American walnut was pasted was polished with P180 sandpaper.
(3) A color treatment was directly applied with a urethane-based colorant, and the colored layer was further covered with a urethane sealer, followed by drying at room temperature for 16 hours.
(4) After drying, it was processed into an arm shape with an NC router.
(5) The portion processed by the NC router was polished with P180 sandpaper.

(6) A urethane sealer of 50 g / m ^{2 was} applied with a brush to the part treated in the above (5) and dried at room temperature for 16 hours.
(7) The portion treated in (6) above was polished with P240 sandpaper.
(8) Image data was taken in with the scanner from the American walnut decorative surface colored in (3) above, and appropriate digital image data was created using image processing software.
(9) A pattern based on the digital image data created in (8) was printed on the portion processed in (7) by an RGB color jet printer.
(10) An unsaturated polyester paint was applied to the entire surface so that the film thickness was 400 μm, dried at room temperature for 16 hours, polished with P800 sandpaper, and then polished with a buff. In the first and second embodiments, the MDF material may be NC-processed and then a decorative plate may be attached to a part thereof.

Next, a third embodiment of the present invention will be described. In the present embodiment, repair was performed on a member that had been damaged by the customer and requested repair (there was a broken corner at the corner of the arm plane). The processing procedure is as follows.
(1) The part which was not damaged was image | photographed with the digital camera. The image data thus created was processed by image processing software to create appropriate digital image data.
(2) The damaged portion was putty-filled and smoothed, and then a pretreatment resin (for facilitating fixing of RGB color jet printer ink) was applied to the surface and dried at room temperature for 4 hours.
(3) Based on the image data created in (1) above, a pattern was printed on the portion processed in (2) above using an RGB color jet printer.

(4) In order to protect the portion on which the pattern was printed in (3) above, a urethane sealer was applied with an air spray gun and dried at room temperature for 16 hours.
(5) The entire surface of the member including the part treated in (4) was polished with P400 sandpaper.
(6) Urethane matte paint (with 60 ° specular gloss of 15 to 20) was applied to the member so as to have a thickness of 15 μm and dried at room temperature for 16 hours.
The member that was corrected by the above processing finished in a workmanship that did not seem to be a corrected product because the pattern and color of the corrected part matched the surrounding pattern.

  As described above, digital image data is generated from the pattern of the part on which the makeup of the member is applied using a scanner, a digital camera, etc., and the pattern based on the digital image data is patterned on the same member. Since the portion which is not printed is printed by an RGB color jet printer or the like, the portion where the pattern was originally attached and the portion where the pattern is printed can be given a sense of unity.

  In addition, since the pattern is printed on the member based on the digital image data, a sample board is not always necessary, and as long as the digital image data can be prepared, any pattern can be applied to any part. Since this can be performed, the degree of freedom in designing the member is remarkably increased. Furthermore, since the digital image data is processed according to the shape of the member and the pattern is printed based on the digital image data after the processing, even if the printing surface of the member has a curved surface portion, printing is possible. The subsequent pattern does not extend and a visually natural decoration effect can be obtained.

  In addition, since plate making costs are not required, a wide variety of members can be obtained. Furthermore, even when repairing due to reasons such as part of the member being missing, digital image data is generated by, for example, photographing the pattern of the part not to be repaired with a digital camera. By processing the digital image data and applying a pattern to the repair target part, it is possible to achieve a finish that does not seem to have been repaired.

  In addition, since the pattern is printed based on the digital image data, the pattern can be easily changed to an accent pattern by changing the color tone without changing the shape of the pattern.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings, but the specific configuration is not limited to these embodiments, and includes design changes and the like within a scope not departing from the gist of the present invention. It is.
