Description

  The present invention relates to a design processing simulation program, a design processing simulation method, and a design processing simulation apparatus that virtually simulate design processing for applying a pattern to a cloth material.

  Conventionally, design processing is one of methods for applying a pattern to the surface of a plain cloth material. The design processing includes print processing and embossing. In the printing process, a pattern is applied to a cloth material by causing a drug (dye) to soak into a portion to be dyed. In actual printing, prints with holes are prepared, and only the holes are dyed. There are three types of printing processes, overprinting, discharge printing, and etching printing, depending on the type of drug.

  In the overprint process, since the dye is infiltrated into the cloth material, the color of the cloth material and the color of the pattern portion are mixed. In the discharge printing process, the fabric material is dyed in the color of the dye because the solid fabric material is decolored and then dyed. Moreover, since the chemical | medical agent which melt | dissolves a cloth raw material is used for an etching print process, the part which the chemical | medical agent penetrate | infiltrated is dented, and an unevenness | corrugation is made in a cloth raw material.

  In the embossing, an uneven metal plate is pressed against a cloth material, and heated and pressed to give an uneven pattern to a flat cloth material. In particular, in embossing, the cloth material is melted by pressurization and the glossiness changes.

Moreover, for example, the technique of Patent Document 1 is known as an apparatus for creating a surface pattern of a fabric. The surface pattern pattern creating device described in Patent Document 1 creates a fabric pattern image from data relating to a dyed fabric.

The details of the penetrating dye amount calculation process will be described later with reference to FIGS.

  Next, in step S <b> 6, the effective coloring dye amount calculation unit 112 calculates, for each pixel, the effective coloring dye amount that dyes the fabric from the penetrating dye amount calculated by the penetrating dye amount calculation unit 111. The details of the effective colored dye amount calculation process will be described later.

  Next, in step S <b> 7, the color determination unit 113 determines the color of the thread after the overprint processing is performed for each pixel. Details of the color determination process will be described later with reference to FIG.

  Next, in step S8, the thread information setting unit 114 sets the thread color determined by the color determination unit 113 as print color information for each pixel. That is, the thread information setting unit 114 sets the print color information associated with each pixel of the texture image data stored in the texture image data storage unit 201 to the thread color determined by the color determination unit 113, respectively. Set.

  In this way, texture image data that is divided into a plurality of pixels and that associates thread information relating to the yarns that make up the fabric for each pixel is acquired, and processing preparation design data that represents the pattern to be applied to the fabric is acquired and acquired. Processing conditions for performing design processing are acquired, including at least a position for performing design processing in the prepared design drawing data. Then, using the acquired processing conditions, the yarn information of each pixel of the texture image data corresponding to the position where the design processing of the processing prepared design drawing data is performed is updated.

  Therefore, since the thread information of each pixel of the texture image data corresponding to the position to which the design processing of the processing prepared design drawing data is applied is updated using the processing conditions for performing the design processing, the texture of the actual design processed product Can be reproduced in a pseudo manner, and the time and cost for creating a prototype can be reduced.

  In addition, the design processing includes a printing process in which a chemical is infiltrated into the woven fabric through a print and a pattern is applied to the woven fabric, and the thread information includes fiber density information indicating the fiber density of the woven fabric, and the processing conditions include Includes resolution information indicating the resolution of the print and scage pressure information indicating the scage pressure at the time of printing. Based on the resolution information, the cage pressure information, and the fiber density information, the amount of penetrating agent that penetrates the fabric into the fabric is calculated for each pixel. Based on the calculated penetrating agent amount, the design processing of the processing preparation design drawing data is performed. The thread information of each pixel of the texture image data corresponding to the position to be applied is updated.

  Therefore, since the yarn information of each pixel of the texture image data corresponding to the position where the design processing of the processing preparation design drawing data is applied is updated based on the amount of the penetrating agent that penetrates the fabric, the amount of the drug In consideration of whether or not the ink penetrates into the woven fabric, the texture of the actual design processed product that has been printed can be reproduced in a pseudo manner.

  Furthermore, the printing process includes an overprint process that allows the dye to penetrate into the fabric through the print, and the thread information includes basic color information indicating the color of the thread before the overprint process and overprint process. Print color information indicating the color of the yarn after application is further included, and the processing conditions further include dye color information indicating the color of the dye. The amount of penetrating dye that permeates the dye into the fabric is calculated for each pixel based on the resolution information, the cage pressure information, and the fiber density information, and the dye is based on the calculated penetrating dye amount and the fiber density information. The effective coloring dye amount for coloring the fabric is calculated for each pixel. After that, based on the calculated effective coloring dye amount, basic color information, and dye color information, the thread color after overprinting is determined for each pixel, and the determined thread color is printed. Color information is set for each pixel.

  Therefore, the amount of penetrating dye that penetrates the fabric into the fabric is calculated for each pixel, the amount of effective coloring dye that dyes the fabric into the fabric is calculated for each pixel, and the color of the thread after overprint processing is calculated for each pixel. The texture of the actual design processed product that has been overprinted in consideration of not only the amount of penetrating dye that penetrates the fabric but also the amount of effective colored dye that actually dyes the fabric. Can be reproduced in a pseudo manner.

  Here, the penetrating dye amount calculation process in step S5 of FIG. 3 will be described. FIG. 4 is a flowchart for explaining the penetrating dye amount calculation processing.

  First, in step S11, the penetrating dye amount calculation unit 111 calculates, as a base dye amount, the amount of dye dropped for each pixel constituting the texture image data based on the resolution information and the cage pressure information. Specifically, the amount of base dye is calculated based on the following formula (1).

Base dye amount = constant × resolution × (scage pressure) ² ... (1)
As shown in the above equation (1), the penetrating dye amount calculation unit 111 calculates the base dye amount by multiplying the value obtained by squaring the scage pressure by the resolution and further multiplying by a constant.

  Next, in step S <b> 12, the penetrating dye amount calculation unit 111 calculates the penetrating amount that the dye penetrates for each pixel based on the fiber density information. Specifically, the penetration amount is calculated based on the following equation (2).

Penetration amount = (penetration coefficient of space without yarn × (1−fiber density) + penetration coefficient of space with yarn × fiber density) × 0.5 (2)
In the above equation (2), the penetration coefficient of the space without the yarn and the penetration coefficient of the space with the yarn are stored in advance according to the type of the fabric and the type of the yarn. As shown in the above equation (2), the penetrating dye amount calculation unit 111 calculates the value obtained by subtracting the fiber density from 1 and the penetration coefficient of the space without the yarn, and the penetration coefficient of the fiber density and the space with the thread. The permeation amount is calculated by adding the value obtained by multiplying by and multiplying by 0.5. The fiber density has a value from 0 to 1, with 0 representing no fiber and 1 representing the highest density.

  Next, in step S13, the penetrating dye amount calculating unit 111 calculates the penetrating dye amount for each pixel. The penetrating dye amount calculation unit 111 calculates the penetrating amount of each pixel as the penetrating dye amount. However, when the penetrating amount exceeds the base dye amount, the penetrating dye amount calculating unit 111 calculates not the penetrating amount but the base dye amount as the penetrating dye amount.

  Next, in step S14, the penetrating dye amount calculation unit 111 adds the penetrating dye amount to the total penetrating dye amount. Next, in step S15, the penetrating dye amount calculation unit 111 subtracts the penetrating dye amount from the base dye amount, and calculates the residual dye amount that could not penetrate into the fiber.

  Next, in step S <b> 16, the penetrating dye amount calculation unit 111 performs a dye spreading process for evenly distributing the residual dye amount to adjacent pixels. Specifically, the penetrating dye amount calculation unit 111 distributes the residual dye amount evenly to the pixels for which the residual dye amount has been calculated and to the eight pixels adjacent to the pixel.

  Next, in step S17, the penetrating dye amount calculation unit 111 sets the value of each pixel obtained as a result of the dye spreading process as the base dye amount, and updates the previously calculated base dye amount.

  Next, in step S18, the penetrating dye amount calculation unit 111 determines whether or not the base dye amount of all pixels is zero. Here, when it is determined that the base dye amount of all the pixels is 0 (YES in step S18), the penetrating dye amount calculation unit 111 proceeds to the process of step S20.

  On the other hand, if it is determined that the base dye amounts of all the pixels are not 0 (NO in step S18), in step S19, the penetrating dye amount calculating unit 111 determines whether or not the penetrating dye amount calculating process has been executed a predetermined number of times. to decide. If it is determined that the predetermined number of times has not been executed (NO in step S19), the process returns to step S13, and the penetrating dye amount calculation unit 111 calculates the penetrating dye amount for each pixel. The penetrating dye amount calculating unit 111 includes a counter that counts the number of times the penetrating dye amount calculating process is executed. The counter sets the count value to 1 before the process of calculating the base dye amount in step S11, and increments the count value when it is determined in step S19 that it has not been executed a predetermined number of times. Further, the predetermined number of times in the present embodiment is set to 100 times, for example.

  On the other hand, if it is determined that the predetermined number of times has been executed (YES in step S19) or if the base dye amount of all pixels is determined to be 0 (YES in step S18), in step S20, the penetrating dye amount calculation unit 111 determines the total penetrating dye amount.

  FIG. 5 is a diagram for explaining the first and second penetrating dye amount calculation processing, and FIG. 6 is a diagram for explaining the third and fourth penetrating dye amount calculation processing. 5 and 6, each cell in 3 rows and 4 columns represents a pixel constituting the texture image data.

  First, the penetrating dye amount calculation unit 111 calculates the base dye amount of each pixel. The base dye amount map A1 represents the base dye amount of each pixel calculated by the penetrating dye amount calculation unit 111. In the base dye amount map A1 shown in FIG. 5, the base dye amounts of the pixel in the second row and the second column and the pixel in the second row and the third column are both 10 for convenience.

  Next, the penetrating dye amount calculation unit 111 calculates the penetrating amount of each pixel. The permeation amount map B1 represents the permeation amount of each pixel calculated by the permeation dye amount calculation unit 111. In the permeation amount map B1 shown in FIG. 5, the permeation amount of the pixel in the third row and third column and the pixel in the third row and fourth column is set to 0 for convenience, and the permeation amount of the other pixels is set to 1 for convenience. Yes.

  Next, the penetrating dye amount calculation unit 111 calculates the penetrating dye amount of each pixel. The penetrating dye amount map C <b> 1 represents the penetrating dye amount of each pixel calculated by the penetrating dye amount calculating unit 111. In the penetrating dye amount map C1 shown in FIG. 5, the penetrating amount is calculated as the penetrating dye amount, but all pixels whose penetrating amount exceeds the base dye amount are changed to the base dye amount. That is, the penetration amount of the pixel in the second row and the second column and the pixel in the second row and the third column are each 1, and the penetration amount of the other pixels is 0.

  Next, the penetrating dye amount calculation unit 111 adds the penetrating dye amount of each pixel to the total penetrating dye amount. The total penetrating dye amount map D1 represents a result of adding the penetrating dye amount of each pixel to the total penetrating dye amount. The initial total penetrating dye amount for each pixel is all zero. Therefore, in the total penetrating dye amount map D1 shown in FIG. 5, the penetrating dye amount of each pixel shown in the penetrating dye amount map C1 is added to the total penetrating dye amount. The penetration amounts of the pixels in the columns are 1 respectively, and the penetration amounts of the other pixels are 0, respectively.

  Next, the penetrating dye amount calculating unit 111 calculates the residual dye amount by subtracting the penetrating dye amount from the base dye amount of each pixel. The residual dye amount map E2 represents the result of subtracting the penetrating dye amount from the base dye amount of each pixel. In the residual dye amount map E2 shown in FIG. 5, the penetrating dye amount of each pixel shown in the penetrating dye amount map C1 is subtracted from the base dye amount of each pixel shown in the base dye amount map A1. The permeation amount of each of the pixels in the second row and the third column is 9 and the permeation amounts of the other pixels are 0, respectively.

  Next, the penetrating dye amount calculation unit 111 updates the base dye amount by evenly distributing the residual dye amount to the pixels for which the residual dye amount has been calculated and the eight pixels adjacent to the pixel. The base dye amount map A2 represents a result in which the residual dye amount is evenly distributed over nine pixels. In the base dye amount map A2 shown in FIG. 5, the residual dye amount shown in the residual dye amount map E2 is evenly distributed to nine adjacent pixels including itself, and the first row, first column, second row, first column. The base dye amounts of the pixels in the 3rd row, the 1st column, the 1st row, the 4th column, the 2nd row, the 4th column, and the 3rd row, 4th column are 1 respectively, 1st row, 2nd column, 2nd row, 2nd column, 3rd row 2 The base dye amounts of the pixels in the first column, the first row, the third column, the second row, the third column, and the third row, the third column are 2, respectively.

  At this time, since all the base dye amounts are not 0 and the number of times the penetrating dye amount calculating process has been performed has not reached a predetermined number (for example, 100 times), the penetrating dye amount calculating process is performed again. The permeation amount map B2 in the second penetrating dye amount calculation process is the same as the permeation amount map B1 in the first penetrating dye amount calculation process. Thereafter, the processing is performed in the same manner as the first time, the penetrating dye amount shown in the penetrating dye amount map C2 is calculated, and the total penetrating dye amount shown in the total penetrating dye amount map D2 is calculated. Then, the residual dye amount shown in the residual dye amount map E3 is calculated, and the base dye amount shown in the base dye amount map A3 is calculated by the dye spreading process.

  At this time, since all the base dye amounts are not 0 and the number of times the penetrating dye amount calculating process has been performed has not reached a predetermined number (for example, 100 times), the penetrating dye amount calculating process is performed again. The permeation amount map B3 in the third penetrating dye amount calculation process is the same as the permeation amount map B1 in the first penetrating dye amount calculation process. Thereafter, the processing is performed in the same manner as the first time and the second time, the penetrating dye amount shown in the penetrating dye amount map C3 is calculated, and the total penetrating dye amount shown in the total penetrating dye amount map D3 is calculated. Then, the residual dye amount shown in the residual dye amount map E4 is calculated. Thereafter, the penetrating dye amount calculation process is repeatedly performed until all the base dye amounts become zero or the number of times the penetrating dye amount calculation process is performed reaches a predetermined number.

  As described above, in the first process, the amount of the dye dropped for each pixel is calculated as the base dye amount based on the resolution information and the cage pressure information, and in the second process, based on the fiber density information. The penetrating dye amount penetrating the dye is calculated for each pixel. In the third processing, the penetrating dye amount is integrated. In the fourth processing, the residual dye amount obtained by subtracting the penetrating dye amount from the base dye amount is adjacent to the surrounding area. The base dye amount is updated evenly distributed to the pixels to be processed, and these processes are repeatedly executed.

  Accordingly, the penetrating dye amount for each region is calculated, and the dye that has not penetrated in each pixel is distributed to adjacent pixels, so that the dye at the boundary between the portion that is overprinted and the portion that is not subjected to the overprint processing The blur can be reproduced in a pseudo manner, and a more realistic overprint process can be reproduced in a pseudo manner.

  Next, the effective coloring dye amount calculation process in step S6 of FIG. 3 will be described. Note that the effective coloring dye amount calculation process varies depending on the type of print processing. The effective colored dye amount calculation unit 112 in the overprint process calculates the effective colored dye amount based on the following equation (3).

Effective coloring dye amount = (0.9 × fiber density + 0.1) × total penetrating dye amount × dye concentration (3)
The dye concentration in the above formula (3) is set to 1 in the present embodiment and does not affect the amount of effective coloring dye, but it is necessary to set the dye concentration with respect to the total penetrating dye amount depending on the type of dye. There is a case. In that case, the dye concentration is set according to the type of the dye.

  Next, the color determination process in step S7 in FIG. 3 will be described. FIG. 7 is a flowchart for explaining color determination processing for overprint processing.

  First, in step S21, the color determination unit 113 converts the RGB value of the basic color information representing the color of the fabric before overprinting into HSV (H: Hue, S: Saturation, V: Lightness) values. . Next, in step S22, the color determination unit 113 converts the RGB value of the dye color information representing the color of the dye into an HSV value. Next, in step S <b> 23, the color determination unit 113 selects the lower lightness value of the lightness value of the basic color information and the lightness value of the dye color information.

  Next, in step S24, the color determination unit 113 calculates a provisional RGB value after dyeing. The temporary RGB values after dyeing are calculated based on the following equation (4).

Temporary RGB value after dyeing = effective color dye amount × RGB value of dye color information × RGB value of basic color information + RGB value of basic color information (1−effective color dye amount) (4)
Next, in step S25, the color determination unit 113 converts the temporary RGB value after dyeing into an HSV value, and calculates the temporary HSV value after dyeing. Next, in step S26, the color determination unit 113 calculates the final brightness value after staining. The final brightness value after dyeing is calculated based on the following equation (5).

Final lightness value after dyeing = Temporary lightness value after dyeing (1-effective coloring dye amount) + low lightness value × effective coloring dye amount (5)
In the above equation (5), the low brightness value is the lightness value of the lower one of the brightness value of the basic color information and the brightness value of the dye color information selected in step S23.

  Next, in step S27, the color determination unit 113 changes the lightness value of the temporary HSV value calculated in step S25 to the final lightness value after dyeing calculated in step S26, and changes the changed temporary HSV value to an RGB value. By converting, the RGB value after staining is calculated. Then, the yarn information setting unit 114 sets the RGB values after dyeing calculated by the color determination unit 113 in the texture image data as print color information.

  As described above, the lightness of the color of the fabric calculated based on the basic color information, the lightness of the dye color calculated based on the dye color information, and the effective coloring dye amount. Based on this, the lightness of the color of the yarn after the overprint processing is corrected. Therefore, the color of the thread after overprinting can be made closer to an actual design processed product.

  FIG. 8 is a diagram illustrating an example of texture image data. FIG. 9 is a diagram illustrating an example of the processing prepared design drawing data. FIG. 10 is a diagram illustrating an example of texture image data subjected to overprint processing.

  As shown in FIG. 8, in the present embodiment, it is also possible to display the texture image data F1 on the display device 6. In FIG. 8, texture image data F1 is displayed in a window W1 on the display screen. The texture image data F1 shown in FIG. 8 is an image obtained by photographing the three-dimensional fabric structure in which the yarn is virtually dyed red with a virtual camera from the front. Yarn information is associated with each pixel constituting the texture image data F1.

  Moreover, as shown in FIG. 9, in this Embodiment, it is also possible to display the process preparation design drawing data T1 on the display apparatus 6. FIG. In the processing prepared design drawing data T1 shown in FIG. 9, the region to be subjected to the design processing is painted with an arbitrary color. An arbitrary color is set as the color of each area of the processing prepared design drawing data T1 at the time of initial setting, and the user can specify the area and color to which the design processing is performed. In the example of FIG. 9, a circular pattern portion M1 to be subjected to design processing is represented in blue.

  Furthermore, as shown in FIG. 10, in the present embodiment, it is also possible to display texture image data F2 that has been virtually overprinted on the display device 6. In FIG. 10, texture image data F2 is displayed in the window W2 of the display screen. The texture image data F2 shown in FIG. 10 represents a simulation result when the pattern portion M1 of the machining preparation design data T1 shown in FIG. 9 is overprinted into the texture image data F1 shown in FIG. In FIG. 10, the pattern portion M2 virtually overprinted is mixed with the dye used for overprinting and the fabric dye, so the fabric color (red) and the dye color (blue) ) Is a mixed color. In addition, the boundary of the pattern portion M2 on which the overprint processing is virtually applied is mixed with a part of the dye to be overprinted and the fabric dye, and gradually changes color from the pattern portion M2 toward the ground portion of the fabric. Changes and appears blurred.

(Discharge printing process)
Next, the discharge printing process will be described. The configuration of the design processing simulation apparatus that virtually performs the discharge printing process is the same as the configuration of the design processing simulation apparatus shown in FIG. 2, and only the function of the color determination unit 113 is different, so only the different functions will be described. . The yarn information and processing conditions used in the discharge printing process are the same thread information and processing conditions as in overprinting.

  The color determining unit 113 calculates a residual color remaining when the fabric is decolored by multiplying the saturation and brightness of the fabric color calculated based on the basic color information by a predetermined coefficient, and an effective coloring dye. Based on the amount, basic color information, dye color information, and residual color, the color of the thread after the discharge printing process is determined for each pixel. In the present embodiment, the color determination unit 113 corresponds to an example of a discharge print color determination unit.

  Next, the printing process in the discharge printing process will be described. Since the printing process in the discharge printing process is different only in the effective colored dye amount calculating process in step S6 and the color determining process in step S7, only the effective colored dye amount calculating process and the color determining process will be described.

  First, an effective coloring dye amount calculation process in the discharge printing process will be described. The effective coloring dye amount calculation unit 112 calculates the effective coloring dye amount based on the following equation (6).

Effective coloring dye amount = (0.4 × fiber density + 0.6) × total penetrating dye amount × dye concentration × 0.9 (6)
The dye concentration in the above formula (6) is set to 1 in the present embodiment, but it may be necessary to set the dye concentration with respect to the total penetrating dye amount depending on the type of dye. In that case, the dye concentration is set according to the type of the dye.

  Next, color determination processing for discharge printing processing will be described. FIG. 11 is a flowchart for explaining color determination processing for discharge printing processing.

  First, in step S31, the color determination unit 113 converts the RGB value of the basic color information representing the color of the fabric before the discharge printing process into an HSV value. Next, in step S <b> 32, the color determination unit 113 calculates residual color information by multiplying the saturation value and lightness value of the basic color information converted into the HSV value by a predetermined coefficient. In the discharge printing process, after the original color of the fabric is decolored, the dye is added and dyed. However, since it is difficult to completely remove the color of the fabric, there is a dye remaining in the fabric. Therefore, by multiplying the saturation value and lightness value of the original color of the fabric by a predetermined coefficient, the color of the remaining dye is calculated as residual color information. Then, by mixing the residual color information and the dye color information, the discharge printing process is virtually simulated. Note that the predetermined coefficient that is multiplied by the saturation value and the lightness value of the basic color information may be set according to the type of medicine used for decolorization.

  Next, in step S <b> 33, the color determination unit 113 calculates the RGB value after decoloring by converting the HSV value of the calculated residual color information into an RGB value. Next, in step S34, the color determination unit 113 determines the residual color information and the dye color information based on the effective color dye amount, the RGB value of the dye color information, the RGB value of the residual color information, and the RGB value of the basic color information. RGB values after dyeing are mixed. The RGB values after dyeing are calculated based on the following equation (7).

RGB value after dyeing = effective color dye amount × RGB value of dye color information × RGB value of residual color information + RGB value of basic color information (1−effective color dye amount) (7)
Then, the yarn information setting unit 114 sets the RGB values after dyeing calculated by the color determination unit 113 in the texture image data as print color information.

  FIG. 12 is a diagram illustrating an example of texture image data that has been subjected to discharge printing processing. In the present embodiment, it is also possible to display the texture image data F3 on which the discharge printing process is virtually performed on the display device 6. In FIG. 12, texture image data F3 is displayed in a window W3 on the display screen. The texture image data F3 shown in FIG. 12 represents a simulation result when the pattern portion M1 of the processing prepared design drawing data T1 shown in FIG. 9 is subjected to discharge printing processing to the texture image data F1 shown in FIG. In FIG. 12, the pattern portion M3 virtually subjected to the discharge printing process is dyed after the fabric color (red) is decolored, and thus has the dye color (blue). The boundary of the pattern portion M3 on which the discharge printing process is virtually performed is a color in which the color of the dye to be subjected to the discharge printing process and the color of the textile dye are mixed.

  As described above, the printing process includes the discharge printing process in which the fabric is decolored according to the pattern and then infiltrated with the dye, and the thread information includes basic color information indicating the color of the thread before the discharge printing process is performed. And print color information representing the color of the yarn after the discharge printing process is included, and the processing conditions further include dye color information representing the color of the dye. The amount of penetrating dye that permeates the dye into the fabric is calculated for each pixel based on the resolution information, the cage pressure information, and the fiber density information, and the dye is based on the calculated penetrating dye amount and the fiber density information. The effective coloring dye amount for coloring the fabric is calculated for each pixel. Thereafter, the color saturation and brightness of the fabric calculated based on the basic color information are multiplied by a predetermined coefficient, thereby calculating residual color information remaining when the fabric is decolored. Based on the effective coloring dye amount, basic color information, dye color information, and residual color information, the color of the thread after the discharge printing process is determined for each pixel, and the determined thread color is used as the print color information. Set for each pixel.

  Therefore, the residual color information remaining when the fabric is decolored is calculated, and the color of the thread after the discharge printing process is determined for each pixel using this residual color information. Therefore, it is possible to simulate a color obtained by mixing the residual color remaining in the ink and the color of the dye, and to simulate a discharge printing process with a more realistic feeling.

(Etching print processing)
Next, etching print processing will be described. In etching print processing, the color of the fabric is not changed according to the pattern, but the height (thickness) of the fabric is changed according to the pattern.

  FIG. 13 is a block diagram for explaining the function of the design processing simulation apparatus in the etching print processing of the present embodiment. In addition, description is abbreviate | omitted about the same structure as the design processing simulation apparatus in the overprint process shown in FIG. 1, and only a different structure is demonstrated. In the etching print processing, fiber density information, basic color information, print color information, and a height value are used as yarn information, and resolution information and cage pressure information are used as processing conditions.

  The yarn information update unit 105 illustrated in FIG. 13 includes a penetrating dye amount calculation unit 111, an effective coloring dye amount calculation unit 112, a height determination unit 115, a fiber density determination unit 116, and a yarn information setting unit 117. The height determination unit 115 subtracts, from the height value, a value obtained by multiplying the effective color dye amount calculated by the effective color dye amount calculation unit 112 by a predetermined coefficient, thereby obtaining a height after etching printing processing. A value is determined for each pixel.

  The fiber density determination unit 116 multiplies the fiber density information by a predetermined coefficient to determine the fiber density information after the etching print processing for each pixel. The yarn information setting unit 117 sets the height value and the fiber density information determined by the height determination unit 115 and the fiber density determination unit 116 for each pixel.

  In this embodiment, the penetrating dye amount calculating unit 111 corresponds to an example of a penetrating agent amount calculating unit, the effective colored dye amount calculating unit 112 corresponds to an example of an effective fixing agent amount calculating unit, and the height determining unit. 115 corresponds to an example of a height determining unit, the fiber density determining unit 116 corresponds to an example of a fiber density determining unit, and the yarn information setting unit 117 corresponds to an example of a yarn information setting unit.

  Next, the printing process in the etching printing process will be described. The printing processing in the etching printing processing is different only in the effective coloring dye amount calculation processing in step S6 and the color determination processing in step S7 in FIG. In the printing process in the etching printing process, not the color determination process but the height and fiber density determination process is performed.

  First, an effective coloring dye amount calculation process in etching print processing will be described. The effective coloring dye amount calculation unit 112 calculates the effective coloring dye amount based on the following equation (8).

Effective coloring dye amount = total penetrating dye amount × dye concentration (8)
The dye concentration in the above formula (8) is set to 1 in the present embodiment, but it may be necessary to set the dye concentration with respect to the total penetrating dye amount depending on the type of dye. In that case, the dye concentration is set according to the type of the dye.

  Next, the height and fiber density determination process for etching print processing will be described. FIG. 14 is a flowchart for explaining the etching print processing height and fiber density determination processing.

  First, in step S41, the height determination unit 115 calculates the height of the fabric after the etching print processing. The height of the fabric after the etching print processing is calculated based on the following equation (9).

Height after etching print processing = Height before etching print processing-Effective coloring dye amount x Height change coefficient (9)
In the above equation (9), a predetermined value is preset for the height change coefficient. In the case of etching print processing, the fabric is not colored by the dye, but the surface of the fabric is dissolved by the chemical. Therefore, the penetrating dye amount calculation unit 111 calculates the amount of penetrating dye that the drug penetrates into the fabric for each pixel based on the resolution information, the cage pressure information, and the fiber density information, and the effective coloring dye amount calculation unit 112 Based on the penetrating dye amount calculated by the penetrating dye amount calculating unit 111 and the fiber density information, the amount of the medicine fixed on the fabric is calculated for each pixel as the effective coloring dye amount.

  Next, in step S42, the fiber density determination unit 116 calculates the fiber density after the etching print processing. The fiber density after this etching print processing is calculated based on the following equation (10).

Fiber density after etching print processing = fiber density before etching print processing × density change coefficient (10)
In the above equation (10), a predetermined value is preset for the density change coefficient. In the woven fabric, the fiber density increases from the surface layer to the ground (lower layer). Therefore, in etching print processing, the height of the fabric is changed and the fiber density is also changed.

  Then, the yarn information setting unit 117 sets the height and the fiber density after etching printing calculated by the height determining unit 115 and the fiber density determining unit 116 in the texture image data as the height value and the fiber density information.

  FIG. 15 is a diagram illustrating an example of texture image data subjected to etching print processing. In the present embodiment, it is also possible to display texture image data F4 that has been virtually subjected to etching print processing on the display device 6. In FIG. 15, texture image data F4 is displayed in a window W4 on the display screen. The texture image data F4 shown in FIG. 15 represents a simulation result when the pattern portion M1 of the machining preparation design data T1 shown in FIG. 9 is etched and printed into the texture image data F1 shown in FIG. In FIG. 15, the pattern portion M <b> 4 virtually subjected to the etching print processing has a change in height, not in the color of the fabric. That is, the height of the handle portion M4 is lower than the other portions, and the border of the handle portion M4 is shaded by a step.

  Thus, the printing process includes an etching printing process that dissolves the surface of the fabric according to the pattern, and the yarn information further includes a height value that represents the height of the fabric. Based on the resolution information, the cage pressure information, and the fiber density information, the amount of penetrating drug that penetrates the fabric into the fabric is calculated for each pixel. Based on the calculated penetrating drug amount and the fiber density information, the drug The amount of effective fixing agent that is fixed to the fabric is calculated for each pixel. Thereafter, a value obtained by multiplying the calculated effective fixing agent amount by a predetermined coefficient is subtracted from the height value, whereby the height value after the etching print processing is determined for each pixel. Further, by multiplying the fiber density information by a predetermined coefficient, the fiber density information after the etching print processing is determined for each pixel. Then, the determined height value and fiber density information are set for each pixel.

  Therefore, the height value after the etching print processing is determined for each pixel, the fiber density information after the etching print processing is determined for each pixel, and the determined height value and the fiber density information are Since it is set for each pixel, the yarn height and the fiber density which are changed by the etching printing process can be reproduced in a pseudo manner, and a more realistic etching printing process can be reproduced in a pseudo manner.

(Embossing)
Next, embossing will be described. Embossing does not change the color or height of the pattern part by infiltrating the fabric with chemicals according to the pattern, but by pressing the mold according to the pattern against the fabric, Change the height.

  FIG. 16 is a block diagram for explaining the function of the design machining simulation apparatus in embossing according to the present embodiment. In addition, description is abbreviate | omitted about the same structure as the design processing simulation apparatus in the overprint process shown in FIG. 1, and only a different structure is demonstrated. In embossing, the yarn information uses a height value, gloss information, and basic color information.

  The processing prepared design drawing data acquired by the processing prepared design drawing data acquisition unit 102 includes depth information indicating the depth to be embossed when embossing is performed. The depth information is data representing the relative depth with respect to the thickness of the fabric, for example, in a grayscale image of 256 gradations, and it is possible to specify the depth of the embossed part and the embossed part. It has become. Generally, the thickness of the fabric is about 1 to 3 mm. If the grayscale image is white (RGB values 255, 255, 255), the depth is 0 and the fabric is not embossed. When the grayscale image is black (RGB values are 0, 0, 0), the fabric is embossed at a depth corresponding to the thickness. In addition, when the gray scale image is an intermediate gradation between white and black (RGB values 128, 128, 128), if the fabric thickness is 1 mm, the fabric is embossed by a depth of 0.5 mm. Is done.

  The processing condition acquired by the processing condition acquisition unit 103 includes pressure information indicating the pressure to be embossed when embossing is performed.

  The yarn information update unit 105 includes a height determination unit 118, a gloss determination unit 119, and a yarn information setting unit 120. The height determining unit 118 determines a height value after embossing for each pixel based on the depth information. The gloss determination unit 119 determines gloss information (gloss value) after embossing for each pixel based on the pressure information. The yarn information setting unit 114 sets the height value determined by the height determination unit 118 and the gloss information determined by the gloss determination unit 119 for each pixel.

  In the present embodiment, the height determining unit 118 corresponds to an example of a height determining unit, the gloss determining unit 119 corresponds to an example of a gloss determining unit, and the yarn information setting unit 120 is an example of a yarn information setting unit. It corresponds to.

  Next, the embossing process by the design processing simulation apparatus shown in FIG. 16 will be described. FIG. 17 is a flowchart for explaining embossing processing by the design processing simulation apparatus.

  First, in step S51, the texture image data acquisition unit 101 acquires texture image data in which thread information is associated with each pixel. This texture image data is the same data as the texture image data in the print processing described above. The texture image data acquisition unit 101 stores the acquired texture image data in the texture image data storage unit 201.

  Next, in step S52, the processing prepared design drawing data acquisition unit 102 acquires processing prepared design drawing data representing a pattern to be applied to the fabric. The processing prepared design drawing data represents a position and depth to be embossed at the time of embossing in a gray scale image, and is created by the user using the input device 1. The processing prepared design drawing data acquisition unit 102 stores the acquired processing prepared design drawing data in the processing prepared design drawing data storage unit 202. In the present embodiment, the processing prepared design drawing data acquisition unit 102 acquires the processing prepared design drawing data created by the user. However, the present invention is not particularly limited to this, and via a network such as the Internet. The processing prepared design drawing data may be acquired from another connected computer.

  Next, in step S53, the processing condition acquisition unit 103 acquires processing conditions when embossing is performed. The machining condition acquisition unit 103 acquires the machining conditions input by the user using the input device 1. That is, the input device 1 accepts input by the user of pressure information representing the pressure to be embossed when embossing is performed, and the processing condition acquisition unit 103 acquires pressure information from the input device 1. The machining condition acquisition unit 103 stores the acquired machining conditions in the machining condition storage unit 203. In the present embodiment, the processing condition acquisition unit 103 acquires the processing conditions input by the user, but the present invention is not particularly limited to this, and other processing connected via a network such as the Internet. Processing conditions may be acquired from a computer.

  Next, in step S54, the height determination unit 118 determines the height value after embossing for each pixel, based on the processing prepared design drawing data. The height determining unit 118 matches the upper left upper end of the process prepared design drawing data with the upper left end of the texture image data, and sets each pixel constituting the process prepared design drawing data and each pixel constituting the texture image data. Associate. Then, the height determination unit 118 calculates the ratio of the depth of embossing to the fabric thickness of each pixel of the processing prepared design drawing data, and multiplies the calculated ratio by the height value of each pixel of the texture image data. Thus, the height value after embossing is determined for each pixel.

  For example, it is assumed that the processing prepared design drawing data is a grayscale image having 256 gradations, and the RGB value of a certain pixel in the processing prepared design drawing data is (100, 100, 100). In this case, the ratio of the embossing depth to the fabric thickness is 100/256, and the height value after embossing is obtained by multiplying this ratio by the height value of the corresponding pixel of the texture image data. It becomes possible.

  In addition, in embossing, there are a case where it is processed into a single woven fabric and a case where urethane fabric is attached to the lining of the woven fabric. Therefore, the depth information is a relative depth with respect to the thickness of the fabric or a relative depth with respect to the total thickness of the fabric and the urethane fabric.

  Next, in step S55, the height determination unit 118 performs a height spreading process for evenly distributing the calculated height value of each pixel to adjacent pixels. Specifically, the height determination unit 118 uniformly distributes the height values to the pixels for which the height values after embossing are calculated and the eight pixels adjacent to the pixels, and after the dispersion is performed. When the height value becomes higher than the height value before dispersion, the height value after dispersion is returned to the height value before dispersion.

  FIG. 18 is a diagram for explaining the height spreading process in step S55 of FIG. In FIG. 18, each cell in 4 rows and 4 columns represents a pixel constituting the processing prepared design drawing data or texture image data.

  The height map G1 represents the depth to be embossed. In the height map G1 shown in FIG. 18, the height of the pixel in the second row and the second column is set to 9 for convenience. The height map G2 represents the height of the original fabric. In the height map G2 shown in FIG. 18, the heights of all the pixels are set to zero.

  The height map G3 represents the height of the fabric immediately after the embossing, that is, after the processing in step S54 is performed. In the height map G3 shown in FIG. 18, the height of the pixel in the second row and the second column is −9. The height map G4 represents the result of the height being evenly distributed over nine pixels. In the height map G4 shown in FIG. 18, the height shown in the height map G3 is evenly distributed to nine adjacent pixels including itself, and the first row, first column, second row, first column, third row. The heights of the pixels in the first column, the first row, the second column, the second row, the second column, the third row, the second column, the first row, the third column, the second row, the third column, and the third row, third column are -1. ing.

  The height map G5 indicates the height of the fabric after application of the constraint that the height of the fabric after the uniform dispersion is higher than the height of the fabric immediately after the stamping, so that the height is adjusted to the height of the fabric immediately after the stamping. Represents. In the height map G5 shown in FIG. 18, the pixel in the second row and the second column is returned to −9 which is the height immediately after the pressing, and the first row, the first column, the second row, the first column, the third row, the first column, The heights of the pixels in the first row, second column, third row, second column, first row, third column, second row, third column, and third row, third column are -1.

  FIG. 18 shows a case where the height spreading process is performed only once, so that the level difference between the embossed part and the adjacent part is large, but this height spreading process is performed a plurality of times. By being repeatedly performed, the boundary of the embossed pattern portion is rounded, and an actual embossed fabric can be reproduced.

  Returning to FIG. 17, in step S <b> 56, the height determination unit 118 determines whether or not the height spreading process has been executed a predetermined number of times. If it is determined that the predetermined number of times has not been executed (NO in step S56), the process returns to step S55, and the height determination unit 118 performs a height spreading process on each pixel. The height determining unit 118 includes a counter that counts the number of times the height spreading process has been executed. The counter sets the count value to 1 after the process of calculating the height after embossing in step S54, and increments the count value when it is determined in step S56 that the predetermined number of times has not been executed. Further, the predetermined number of times in the present embodiment is set to 100 times, for example.

  On the other hand, when it is determined that the predetermined number of times has been executed (YES in step S56), in step S57, the gloss determination unit 119 determines the gloss value after embossing for each pixel based on the pressure information. That is, the gloss determination unit 119 determines a gloss value after embossing by selecting a coefficient corresponding to the magnitude of the acquired pressure and multiplying the gloss value by the selected coefficient. At this time, as the pressure at the time of embossing increases, the selected coefficient increases and the gloss value also increases.

  Next, in step S58, the yarn information setting unit 114 sets the height value determined by the height determination unit 118 and the gloss value determined by the gloss determination unit 119 for each pixel.

  The texture image data subjected to the embossing process is substantially the same as the texture image data F4 subjected to the etching print process shown in FIG. The pattern portion of the texture image data subjected to the embossing process has a gloss value larger than that of the pattern portion M4 of the texture image data F4 subjected to the etching print process, and the boundary of the pattern portion is rounded.

  As described above, the design processing includes embossing that forms unevenness on the surface of the fabric by embossing, and the yarn information includes the height value that represents the height of the fabric and the yarn that constitutes the fabric. The processing conditions include pressure information indicating the pressure to be embossed when embossing is performed, and the work preparation design data includes the mold information when embossing is performed. Depth information indicating the depth to be pressed is included. Then, the height value after embossing is determined for each pixel based on the depth information, and the gloss information after embossing is determined for each pixel based on the pressure information. A height value and gloss information are set for each pixel.

  Therefore, the height value after embossing is determined for each pixel, the gloss information after embossing is determined for each pixel, and the determined height value and gloss information are set for each pixel. Therefore, the yarn height and gloss information that change due to the embossing can be reproduced in a pseudo manner, and a more realistic embossing can be reproduced in a pseudo manner.

  Also, in the first process, the height value after embossing is calculated for each pixel, and in the second process, the calculated height value is evenly distributed to neighboring pixels, If the height value calculated in the second process is higher than the height value calculated in the first process, the height value calculated in the second process is the height calculated in the first process. Returning to the value, these processes are repeated.

  Therefore, if the height value calculated for each pixel is evenly distributed to neighboring pixels and the height value after dispersion is higher than the height value after embossing, Since the height value is returned to the height value after embossing, the roundness at the boundary between the embossed part and non-embossed part can be simulated and more realistic. Embossing can be simulated.

  The design processing simulation apparatus in the present embodiment performs overprint processing, discharge printing processing, etching print processing, and embossing separately, but the present invention is not particularly limited thereto, and overprint processing, A plurality of discharge printing processes, etching printing processes, and embossing processes may be combined.
