Thereby, the design is printed in a dot shape with a predetermined resolution. Patent Document 1 discloses a printing method for an instrument panel using such an ink jet apparatus.
JP 2006-221044 A

  In a printing method using an inkjet device, when a design is printed so that the outline of the design is in a direction intersecting the X and Y directions, the design is formed with stepped resolution. For example, when printing at 600 dpi (Dot Per Inch) × 600 dpi, a dot-like step-like outline of 0.042 (25.4 / 600) mm is formed, and the design has a jagged feeling.

  The present invention has been made in view of the above points, and an object of the present invention is to alleviate the jaggedness of a design to be printed in an instrument board printing apparatus and an instrument board printing method provided with an inkjet device.

  In order to achieve the above object, the present invention employs the following technical means.

  According to the first aspect of the present invention, based on a control device that controls printing of the design so as to print the design formed on the surface of the substrate constituting the instrument panel in a dot shape, and a command from the control device. An inkjet device that moves relative to the substrate in the XY direction and prints the design on the surface of the substrate in the form of dots, and the control device controls the printing so that the design contour is XY. The first resolution dot-shaped printing design is formed on the surface of the substrate so as to cross the direction, and the design is shifted by a predetermined amount in at least one of the XY directions to form a first resolution dot-shape. It is characterized by being formed on the surface of the printing design as a complementary printing design.

  According to this configuration, since the print design formed so that the outline of the design is in the direction intersecting the XY direction is formed with the first resolution in a stepped shape, a jagged feeling is generated in the print design. Furthermore, according to this configuration, the complementary printing design formed by shifting the design by a predetermined amount in at least one of the XY directions is shifted from the printing design, and thus the printing design and the complementary printing design do not overlap. Is generated on the contour side of the printed design. Since the printing density of the non-overlapping portion is lower than the printing density of the portion where the printing design and the complementary printing design overlap, the jagged feeling of the design can be alleviated by the portion where the printing density is low.

  According to the second and third aspects of the present invention, the shift amount of the complementary print design with respect to the print design is a second resolution smaller than the first resolution.

  Since the second resolution, which is the shift amount of the complementary print design relative to the print design, is smaller than the first resolution of the print design, the portion where the print design and the complementary print design do not overlap is jagged due to the staircase-shaped first resolution. It is getting smaller. Therefore, it is possible to alleviate the jaggedness of the design while making the non-overlapping portion less noticeable than the jaggedness due to the step-like first resolution.

  According to the invention described in claim 4, the printed design has a contour in which a contour portion in one direction is set shorter than a contour portion in another direction in the XY direction.

  Here, when the direction in which the design is shifted does not coincide with the direction in which the contour portion is set to be dimensionally short, the shift amount of the complementary printing design with respect to the printing design is small. For this reason, the part where the printing design and the complementary printing design do not overlap becomes small, and the jagged feeling of the design cannot be effectively reduced.

  On the other hand, according to this configuration, since the direction in which the design is shifted is the direction in which the contour portion is set to be short in dimension, the shift amount of the complementary printing design with respect to the printing design is increased. For this reason, the part where the printing design and the complementary printing design do not overlap is enlarged, and the jaggedness of the design can be effectively reduced.

  According to the invention described in claim 5, the complementary printing design is repeatedly formed a plurality of times, and the second resolutions of the plurality of complementary printing designs are made different from each other each time the complementary printing design is repeated a plurality of times. To do.

  According to this configuration, the second resolutions of the shift amounts of the plurality of complementary printing designs with respect to the printing design are made different from each other.

  For this reason, for example, when the complementary printing design is repeated three times, in the portion where the printing design and the complementary printing design do not overlap, a portion where the complementary printing design overlaps three times and a portion where the complementary printing design overlaps twice due to different second resolutions And a single portion are formed. The print density of one part is lower than the print density of two parts, and the print density of two parts is lower than the print density of three parts. Therefore, the jaggedness of the design can be further alleviated by the portion composed of the three types of print density portions.

  According to the invention described in claim 6, the design formed as the complementary printing design is a part of the overall design formed on the surface of the substrate, and the complementary printing design is formed by shifting the entire design by a predetermined amount. It is a part of the formed overall printing design.

  According to this configuration, the complementary printing design is not individually formed, but the entire printing design is formed by shifting the entire printing by a predetermined amount, and the complementary printing design is used as a part thereof. For this reason, the printing process time can be shortened, and the jaggedness of the design can be reduced by shortening the printing time.

  According to the seventh to twelfth aspects of the present invention, the same effects as those of the first to sixth aspects can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, the same reference numerals are assigned to the same or equivalent parts in the drawings.

(First embodiment)
A printing apparatus 1 shown in FIG. 1 includes a memory 31 that stores a design printed on a substrate 11 as image data, an inkjet device 2, a control device 3, and a substrate stage 4 to which the substrate 11 is fixed. Prepare. The printing apparatus 1 is configured such that the inkjet apparatus 2 moves relative to the substrate 11 in the X and Y directions along the substrate 11.

  The inkjet apparatus 2 forms a printing film 12 by ejecting a printing material from the nozzle head electronically controlled by the control apparatus 3 as ink droplets 2 </ b> A onto the substrate 11, thereby forming a design on the substrate 11. A design is printed on a substrate 11 made of a transparent resin substrate such as polycarbonate to form a dial 10.

  In the example shown in FIG. 1, the memory 31 is a memory that is built in the control device 3 and includes a nonvolatile memory or a backup RAM (random access memory) that can electrically rewrite stored data.

  The control device 3 is composed of a microcomputer or the like, and forms bitmap data by performing RIP (Raster Image Processor) processing on the image data in the memory 31, and controls printing by the inkjet device 2 based on the bitmap data. Bitmap data is data representing dots (dots) that are regularly arranged in an image, and can be printed by the inkjet device 2 that prints dots in a predetermined resolution based on the bitmap data expressed in dots. It becomes. The control device 3 performs the ejection control of the ink droplet 2A from the ink jet device 2 and the relative movement control of the ink jet device 2 with respect to the substrate 11 based on the bitmap data subjected to the RIP process.

  In the dial 10 shown in FIG. 2, designs such as letters 15 and scales 16 are formed as openings in the black background layer 13 that is a part of the printing film 12.

  The printing apparatus 1 corresponds to the instrument panel printing apparatus described in the claims, the memory 31 corresponds to the storage means described in the claims, the dial 10 corresponds to the instrument panel described in the claims, The character 15 and the scale 16 correspond to the design described in the claims.

  In order to perform dot-like printing from the inkjet apparatus 2 based on the bitmap data, in the region shown in FIG. 3, the outline 17 of the scale 16 inclined with respect to both the X and Y directions has a dot width YR in the Y direction. Are formed with a step-like resolution having a level difference 18. For example, when printing at 600 dpi (Dot Per Inch) × 600 dpi, the dot width YR is 0.042 (25.4 / 600) mm. The step 18 having the dot width YR occurs in the Y direction on the side of the X and Y directions where the inclination angle with the contour 17X is large. The reason why the level difference 18 does not occur in the contour 17X while the level difference 18 does not occur in the contour 17Y is because the contour 17Y is short.

  In the region shown in FIG. 3, as shown in FIG. 4, the black background layer 13 is printed four times by overlapping the application of the ink droplet 2 </ b> A four times, thereby forming the region 142. The area 140 where the black background layer 13 is not printed is used as the scale 16 as the opening of the area 142. In the area shown in FIG. 3, printing by the inkjet device 2 based on the image data in the memory 31 is performed four times, and the contour 17 representing at least a part of the design including the character 15 and the scale 16 is in both the X and Y directions. It can be said that the region is inclined with respect to the angle. Further, the area shown in FIG. 3 has a dot-like scale (see FIG. 7) having a predetermined resolution so that an outline 17 representing at least a part of the design including the character 15 and the scale 16 intersects both the X and Y directions. It can be said that it is a region formed on the surface of the substrate 11 as a scale (indicated by the outline 17A).

  A light source that illuminates and transmits the dial 10 is disposed behind the dial 10. Designs such as the characters 15 and scales 16 that are formed as openings in the black background layer 13 receive illumination light from the light source. It is configured to display light. In order to sufficiently secure the light shielding property of the background layer 13, the black background layer 13 is printed four times in the region 142. Between the area | region 140 and the area | region 142, the area | region 141 which piled up and printed the black background layer 13 twice is formed.

  Below, the formation method of the area | region 141 is demonstrated based on FIGS.

  In step S1 shown in FIG. 5, the control device 3 performs RIP processing on the image data in the memory 31 to form bitmap data. In step S2, printing by the inkjet device 2 based on the bitmap data is performed twice. Do. The contour 17 on the image data shown in FIG. 6 is a step-like first-resolution contour 17A in which the step 18 having the dot width YR is separated from the predetermined inter-step distance L by the printing in step S2, as shown in FIG. Formed as.

  In step S3, as schematically shown in FIG. 6, the control device 3 outputs image data by shift amounts X1 and Y1 smaller than the resolution on the image data corresponding to the dot widths XR and YR in both the X and Y directions. The complementary image data is formed by shifting, and in step S4, the complementary image data is RIP processed to form complementary bitmap data. The shift amounts X1 and Y1 correspond to shift amounts smaller than the dot widths XR and YR of 0.042 mm. In the example of this embodiment, the shift amounts X1 and Y1 are 0.021 mm, but the present invention is not limited to this. In step S5, the control device 3 performs the printing by the ink jet device 2 based on the complementary bitmap data twice. The contour 171 on the complementary image data shown in FIG. 6 is formed as a step-like contour 171A in which the step 181 having the dot width YR is separated from the inter-step distance L by the printing in step S5, as shown in FIG.

  The scale 16 shown in FIG. 3 is formed by superimposing the scale shown by the outline 171A in FIG. 8 formed in step S5 on the scale shown by the outline 17A in FIG. 7 formed in step S2. Note that the IX portion shown in FIG. 3, the IXA portion shown in FIG. 7, and the IXB portion shown in FIG.

  Steps S1 and S2 correspond to the first step recited in the claims, and steps S3 to S5 correspond to the second step recited in the claims. The scale indicated by the outline 17A in FIG. 7 formed in step S2 corresponds to the printed design described in the claims, and the scale indicated by the outline 171A in FIG. 8 formed in step S5 is described in the claims. Corresponds to complementary printing design.

  As shown in FIG. 9, when the image data is shifted by Y1 in the Y direction, the steps 18 and 181 that occur in the Y direction are the distance L between steps (printing based on bitmap data and printing based on complementary bitmap data). In the example shown in FIG. 9, it is less than 16 times the dot width XR) and is shifted from each other in the X direction by a natural number times the dot width XR (8 times in the example shown in FIG. 9). This is because, by shifting Y1 in the Y direction from the contour 17 on the image data to the contour 171 on the complementary image data, the same step-shaped first from the contour 17A formed at the step-shaped first resolution with the distance L between steps. This is because the outline 171A formed at one resolution is shifted by a second resolution smaller than the first resolution (eight times the dot width XR).

  A region 141 is formed as a portion where the printing based on the bitmap data shown in FIG. 7 and the printing based on the complementary bitmap data shown in FIG. The In the example shown in FIG. 9, the region 141 is indicated by a set of rough broken-line circles printed by overlapping the ink droplets 2 </ b> A twice. On the other hand, the printing based on the bitmap data and the printing based on the complementary bitmap data are overlapped to form a region 142 indicated by a set of solid circles printed by overlapping the ink droplets 2A four times, and the ink droplets 2A are printed. A region 140 indicated by a set of fine broken circles is formed. Note that a fine broken line, a rough broken line, and a solid circle each schematically show the ink droplet 2A.

  Since the print density of the area 141 printed twice is lower than the print density of the area 142 printed four times, the area 141 is compared with the area 142 from the light source arranged behind the dial 10. The transmission of illumination light increases. Therefore, in FIG. 3, a brightness area 141 between the areas 140 and 142 is formed between the light emitting display area 140 and the area 142 in which sufficient light shielding is ensured. It can be said that the area 141 is an area having an appropriate area that is less than the distance L between steps and is an area that is a natural number times the dot width XR, and that is not too large and is not too small to be visually recognized.

  Thus, the level difference 18 is relaxed and visually recognized by the area 141 having an appropriate area which is the brightness between the areas 140 and 142, which is not too large and is not too small to be visually recognized. . Therefore, in FIG. 3, the jagged feeling of the scale 16 can be alleviated and not noticeable. Furthermore, since the region 141 is formed with a second resolution smaller than the stepwise first resolution with a step-to-step distance L, the scale is made inconspicuous from the jaggedness due to the stepwise first resolution. 16 jaggedness can be eased.

  In the contour 17A shown in FIG. 7, the Y-direction contour portion (contour portion with the dot width YR) is set to be dimensionally shorter than the X-direction contour portion (contour portion with the distance L between steps). Here, when the complementary bitmap data is formed by shifting the image data by X1 in the X direction without shifting the image data in the Y direction, the difference between the step 18 based on the bitmap data and the step based on the complementary bitmap data. However, it becomes smaller. For this reason, the portion where the printing based on the bitmap data and the printing based on the complementary bitmap data do not overlap (region corresponding to the region 141) becomes small, and the jagged feeling of the scale having the step 18 cannot be effectively alleviated. .

  On the other hand, in this embodiment, the complementary bitmap data is formed by shifting the image data in the Y direction in which the contour portion is set to be dimensionally short. For this reason, the gap between the step 18 based on the bitmap data and the step 181 based on the complementary bitmap data can be increased. Therefore, the area 141 which is a portion where the printing based on the bitmap data and the printing based on the complementary bitmap data do not overlap with each other becomes larger, and the jagged feeling of the scale 16 can be effectively reduced.

  As described above, since the contour 17Y shown in FIG. 3 is short, there is no step in the X direction in the contour 17Y. Therefore, even if the displacement of X1 in the X direction is omitted in FIG. An effect can be obtained.

  If there is a step in the X direction, the image data is shifted in the X direction by a shift amount X1, so that the step in the X direction is also printed based on bitmap data and printing based on complementary bitmap data. It is less than the distance between steps and is shifted from each other in the Y direction by a natural number multiple of the dot width YR. Thereby, the step in the X direction can be effectively reduced.

(Second Embodiment)
In the second embodiment, as shown in FIG. 10, the region 141 is formed by being divided into a region 141A in which the black background layer 13 is printed twice and a region 141B in which the black background layer 13 is printed once. To do.

  Below, the formation method of area | region 141A, 141B is demonstrated based on FIG.

  In steps S1 and S2 shown in FIG. 11, the control device 3 performs printing by the inkjet device 2 based on the bitmap data twice.

  In step S6, the control device 3 forms the first complementary image data by shifting the image data by a shift amount Y1 smaller than the resolution on the image data corresponding to the dot width YR in the Y direction. In step S7, the first complementary image data is formed. The complementary image data is RIP processed to form first complementary bitmap data. In step S8, the control device 3 performs printing once by the inkjet device 2 based on the first complementary bitmap data.

  In step S9, the control device 3 forms the second complementary image data by shifting the image data by a shift amount smaller than the shift amount Y1 and different from X1, and in step S10, the second complementary image data is RIP. Process to form second complementary bitmap data. In step S11, the control device 3 performs printing once by the ink jet device 2 based on the second complementary bitmap data. In the present embodiment, in order to simplify the description, the shift amount X1 in the X direction is omitted.

  Steps S1 and S2 correspond to the first step recited in the claims, and steps S6 to S11 correspond to the second step recited in the claims. Two times, which is a total of one printing in step S8 and one printing in step S11, corresponds to a plurality of times described in the claims.

  As shown in FIG. 12, with reference to the step 18 based on the complementary bitmap data, the deviation of the step 181 based on the first complementary bitmap data (8 times the dot width XR in the example shown in FIG. 12) is the second complementary bitmap. This is different from the deviation of the step 182 based on the data (in the example shown in FIG. 12, four times the dot width XR). This is the second resolution (eight times the dot width XR), which is the shift amount between the steps 18, 181 and the shift amount between the steps 18, 182 by making the shift amounts Y1, Y2 different from each other. It can be said that the second resolutions (four times the dot width XR) are different from each other. In the example shown in FIG. 12, the step 182 is formed between the steps 18 and 181. This is because the shift amount Y2 is set smaller than the shift amount Y1, and therefore the contour 172 on the second complementary image data is arranged between the contour 17 on the image data and the contour 171 on the first complementary image data. It is because it was done.

  In the area 141, due to the difference between the steps 181 and 182, the area 141 </ b> A in which the printing based on the first and second complementary bitmap data overlaps twice and the printing only based on the printing based on the first complementary bitmap data are performed once A region 141 </ b> B that is a portion of is formed. For this reason, a region 141B in which the ink droplets 2A are printed once is formed, and a region 141B indicated by a set of thick and fine broken circles is formed, and a rough broken line in which the ink droplets 2A are printed twice is printed. A region 141A indicated by a set of circles is formed. A fine broken line, a rough broken line, a thick and fine broken line, and a solid line circle schematically show the ink droplet 2A, respectively.

  Since the printing density of the area 141B printed once is lower than the printing density of the area 141A printed twice, the area 141B is compared with the area 141A from the light source arranged behind the dial 10. The transmission of illumination light increases. Therefore, in FIG. 10, the areas 141A and 141B having the brightness between the areas 140 and 142 are formed with different brightness between the area 140 for light-emitting display and the area 142 with sufficient light shielding properties. The

  Accordingly, the step 18 of the dot width is more relaxed and visually recognized by the two types of brightness areas 141A and 141B. For this reason, the jagged feeling of the scale 16 can be more relaxed and less noticeable.

  In FIG. 11, the number of times of printing in step S2 is set to one, and the third complementary image data is formed by shifting the shift amount Y3 having a resolution different from the shift amounts Y1 and Y2, and the third complementary image data is subjected to RIP processing. It is also possible to form third complementary bitmap data. If printing is performed once based on the third complementary bitmap data, the brightness between the areas 140 and 142, which is three different brightness areas, is formed between the areas 140 and 142. Can do. Therefore, the jagged feeling of the scale 16 can be further relaxed and made inconspicuous.

  In the above-described example, the scale 16 is described as an example, but the same effect can be obtained even in a design such as the character 15.

  Note that printing by the inkjet apparatus 2 based on the image data in the memory 31 is performed a plurality of times, and a contour 17 representing at least a part of the design including the characters 15 and the scales 16 is inclined with respect to both the X and Y directions. It is also possible to form complementary image data (including first and second complementary image data) individually for each area, and to form complementary bitmap data individually, but this is not a limitation. For example, the entire image data is collectively processed to form complementary image data for all areas and complementary bitmap data for all areas, and the complementary bitmap data for each area is a part of the complementary bitmap data for all areas. It is also possible to use as. As a result, the processing time can be shortened, and the jaggedness of the design can be reduced by reducing the printing time.

  Moreover, it is also possible to perform printing by the inkjet apparatus 2 collectively based on the complementary bitmap data of the entire area. Thereby, the printing time can be shortened.
