Description

Technical Field

[0001] This invention relates to the field of printing technology, and in particular to a printing control method, apparatus, and equipment for improving the breathability of fabrics. Background Technology

[0002] Halftone technology refers to the technique of quantizing a continuous-tone image (such as a grayscale or color image) into a binary image or a color image with only a few colors using a small number of colors, and ensuring that the quantized image visually resembles the original image at a certain distance. As is well known, digital halftone technology is a technique that, based on the characteristics of human vision and image color rendering, utilizes mathematical and computer tools to achieve optimal image reproduction on monochrome / multicolor binary color rendering devices. Digital halftone leverages the low-pass characteristic of the human eye; when viewed at a certain distance, the human eye perceives spatially proximate parts of an image as a whole. Utilizing this characteristic, the local average grayscale of the halftone image observed by the human eye approximates the local average grayscale value of the original image, thus creating an overall continuous-tone effect.

[0003] The application of halftone technology in the modern digital printing industry can replace the traditional dyeing process in the textile industry, which improves efficiency and is also low-carbon and environmentally friendly.

[0004] In the field of digital printing, there is a technology called "powder-shaking machine technology." Its basic principle is to use a hot-melt material, such as hot-melt powder, to adhere to white ink or other inks. Through high-temperature pressing, the white and colored inks are bonded to the fabric, resulting in rich and vibrant colors and patterns. A common problem with powder-shaking machine technology is the difficulty in controlling the amount of white ink and hot-melt powder used. Insufficient use can cause ink to detach, affecting product lifespan, while excessive use can lead to poor fabric breathability, negatively impacting user experience. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a printing control method, apparatus and equipment for improving the breathability of fabrics, in order to solve the technical problem of poor fabric breathability caused by the difficulty in controlling the amount of printing consumables such as white ink and hot melt powder in the prior art.

[0006] In a first aspect, embodiments of the present invention provide a printing control method for improving the air permeability of fabrics, the method comprising:

[0007] S10: Obtain the image to be printed;

[0008] S20: Divide the image to be printed into a first printing area and a second printing area; wherein, the first printing area is the area that needs to be covered with a specified printing material, and the second printing area is the area that does not need to be covered with a specified printing material.

[0009] S30: Select a third printing area from the first printing area; wherein, the third printing area includes multiple non-connected areas, the area of ​​the third printing area is smaller than the first printing area, and the area in the first printing area other than the third printing area is denoted as the fourth printing area;

[0010] S40: Set the specified printing consumable usage in the third printing area to be non-zero, and set the specified printing consumable usage in the fourth printing area to be zero;

[0011] S50: Use the specified printing consumables to perform a base printing on the first printing area.

[0012] This invention divides the image to be printed into a first printing area and a second printing area to determine the area requiring a base coat of a specified printing material. Then, a third printing area is selected from this area, ensuring that the third printing area includes multiple non-connected regions and that its area is smaller than the first printing area. The specified printing material is then used only in the third printing area for base coat printing. By controlling the application range of the specified printing material, the breathability of the fabric can be effectively guaranteed. Furthermore, because the third printing area includes multiple non-connected regions, the uniform distribution of the specified printing material can be maximized, thereby ensuring print quality and original appearance as much as possible. Figure 1 It ensures good ink adhesion, especially when using hot melt powder as the designated printing consumable for underlay printing, thus maximizing the effective adhesion of inks.

[0013] Preferably, S30 includes: selecting a third printing area from the first printing area according to a rule of spacing a specific shape, wherein the specific shape is a circle and / or a polygon.

[0014] In this embodiment of the invention, a third printing area is selected from the first printing area according to a rule of specific shapes, so that the area for base printing is evenly distributed, thereby maximizing the uniform distribution of the specified printing consumables and ensuring the best possible print quality and originality. Figure 1 It ensures good ink adhesion, especially when using hot melt powder as the designated printing consumable for underlay printing, thus maximizing the effective adhesion of inks.

[0015] Preferably, step S30 includes: processing the first printing area according to an amplitude modulation dot matrix algorithm to select the third printing area.

[0016] In this embodiment of the invention, the first printing area is processed by an amplitude modulation dot matrix algorithm. The distribution of the third printing area can be controlled by controlling the size of the dots, so as to achieve the best printing effect by continuously optimizing the dot size.

[0017] Preferably, in step S40, setting the amount of designated printing consumables in the third printing area to be non-zero includes setting the concentration of designated printing consumables in the third printing area to 100%.

[0018] In this embodiment of the invention, by setting the concentration of the designated printing consumable in the third printing area to 100%, printing is performed using 100% of the designated printing consumable, which can ensure the printing quality as much as possible. In particular, when using hot melt powder as the designated printing consumable for underlay printing, it can maximize the effective adhesion of ink.

[0019] Preferably, in step S40, setting the amount of designated printing consumables in the third printing area to be non-zero includes: setting the concentration of designated printing consumables in the third printing area according to the ink concentration of the third printing area.

[0020] In this embodiment of the invention, the concentration of a specified printing consumable in the third printing area is set by the color ink concentration of the third printing area. This allows for the control of the specified printing consumable based on the change in color ink concentration, thereby optimizing the amount of specified printing consumable and improving the breathability of the fabric while ensuring printing quality.

[0021] Preferably, in step S40, setting the specified printing consumable usage in the third printing area to be non-zero includes:

[0022] S41: Perform halftone processing on the image to be printed to obtain halftone data;

[0023] S42: Set the specified printing consumable usage for the third printing area based on the network data.

[0024] This invention, through setting the amount of designated printing consumables for a third printing area based on the dot data, controls the amount of designated printing consumables based on the distribution of dot data, optimizes the use of designated printing consumables, and improves the breathability of the fabric while ensuring printing quality.

[0025] Preferably, the specified printing consumable is one or more of white ink, hot melt powder, and processing liquid.

[0026] Secondly, embodiments of the present invention provide a printing control device for improving the breathability of fabrics, the device comprising:

[0027] The image acquisition module is used to acquire the image to be printed;

[0028] The region segmentation module is used to divide the image to be printed into a first printing region and a second printing region; wherein, the first printing region is the region that needs to be covered with a specified printing material, and the second printing region is the region that does not need to be covered with a specified printing material.

[0029] The region selection module selects a third printing region from the first printing region; wherein, the third printing region includes multiple non-connected regions, the area of ​​the third printing region is smaller than that of the first printing region, and the region in the first printing region other than the third printing region is denoted as the fourth printing region;

[0030] The consumables setting module allows you to set the specified consumables usage in the third printing area to be non-zero, and to set the specified consumables usage in the fourth printing area to be zero.

[0031] The printing control module is used to perform a base printing on the first printing area using specified printing consumables.

[0048] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0050] In current digital printing technology, a hot-melt material (such as hot-melt powder) is first applied to white ink. Then, white ink is used to lay the base on the product (such as a T-shirt) to form a white ink layer. Finally, colored ink is printed on top of this white ink layer to obtain a colored pattern (colored ink layer). Based on this principle, if too little hot-melt powder is used, the inks may not adhere effectively; if too much hot-melt powder is used, the printability may be insufficient. Similarly, if too little white ink is used, the colored inks may not be effectively highlighted; if too much white ink is used, the printability may be insufficient. Therefore, existing powder-dispensing machines struggle to precisely control the amount of printing consumables such as hot-melt powder and white ink, easily leading to poor print quality or insufficient printability.

[0051] In view of this, embodiments of the present invention provide a printing control method for improving the air permeability of fabrics; please refer to [link to relevant documentation]. Figure 1 The method includes:

[0052] S10: Obtain the image to be printed;

[0053] S20: Divide the image to be printed into a first printing area and a second printing area; wherein, the first printing area is the area that needs to be covered with a specified printing material, and the second printing area is the area that does not need to be covered with a specified printing material.

[0054] S30: Select a third printing area from the first printing area; wherein, the third printing area includes multiple non-connected areas, the area of ​​the third printing area is smaller than the first printing area, and the area in the first printing area other than the third printing area is denoted as the fourth printing area;

[0055] S40: Set the specified printing consumable usage in the third printing area to be non-zero, and set the specified printing consumable usage in the fourth printing area to be zero;

[0056] S50: Use the specified printing consumables to perform a base printing on the first printing area.

[0057] Specifically, after obtaining the image to be printed, it can be divided into a first printing area and a second printing area based on the color distribution of the image. For example, if the color mode of the image to be printed is CMYK, the CMYK value of each pixel can be used to determine whether each pixel belongs to the first or second printing area. Of course, this invention does not limit the color mode of the image to be printed; other color modes such as RGB and LAB do not affect the implementation of this embodiment.

[0058] In one embodiment of the present invention, the determination can be made based on the relationship between the color value and the threshold of each color channel. If the color value is greater than the threshold, it is determined that the color channel needs to be underprinted. When one or more color channels need to be underprinted, the pixel is assigned to the first printing area. For example, if a pixel has color values ​​of (C=10%, M=20%, Y=30%, K=0) and the threshold is 15%, then there are two color channels with color values ​​greater than the threshold. To ensure the printing effect of the colored ink, this pixel needs to be underprinted with white ink before the colored ink layer is printed, and therefore it is assigned to the first printing area.

[0059] In another embodiment of the present invention, the determination can also be made based on the relationship between the sum of the color values ​​of each color channel and the threshold. If the sum of the color values ​​is greater than the threshold, it is determined that underlay printing is required. For example, if there is a pixel with color values ​​of (C=10%, M=20%, Y=30%, K=0), and the threshold is 70%, the sum of the color values ​​of the four color channels is 60%. To ensure breathability, there is no need to use white ink for underlay printing, so this pixel is assigned to the second printing area.

[0060] In another embodiment of the present invention, the dot data of the image to be printed can also be used to divide the first printing area and the second printing area. The dot data is obtained based on halftone processing of the image to be printed. For example, if 1-bit halftone processing is performed, the dot data type includes 0 and 1, where dot data 0 is used to indicate that the corresponding color channel is not printed, and dot data 1 is used to indicate that the corresponding color channel is printed. If 2-bit halftone processing is performed, the dot data type includes 00, 01, 10, and 11, where dot data 00 is used to indicate that the corresponding color channel is not printed, dot data 01 is used to indicate that the corresponding color channel is printed with small ink dots (e.g., 25%), dot data 10 is used to indicate that the corresponding color channel is printed with medium ink dots (e.g., 50%), and dot data 11 is used to indicate that the corresponding color channel is printed with large ink dots (e.g., 100%). Therefore, by analyzing the type of data at each dot in the dot data, it can be determined whether each color channel (such as CMYK) needs to be printed. When there is one or more color channels that need to be printed with colored ink, in order to ensure the printing effect of the colored ink, white ink needs to be used for base printing before the colored ink layer is printed at that pixel, so it is assigned to the first printing area.

[0061] To allow for more flexible division of the first and second printing areas, users can also adjust the selection using image editing software (such as Photoshop).

[0062] Obviously, those skilled in the art can obtain other ways to divide the first printing area and the second printing area by simple transformations based on the content disclosed in the embodiments of the present invention.

[0063] For easier understanding, please refer to Figure 2 The image to be printed is divided into a first printing area 10 and a second printing area 20 through the aforementioned steps. Then, a third printing area can be selected from the first printing area 20.

[0064] In one embodiment of the present invention, a third printing area is selected from the first printing area according to a rule of spacing specific shapes, wherein the specific shapes are circles and / or polygons.

[0065] For example, such as Figure 3 As shown, a third printing area 30 is selected from the first printing area 10 according to the rule of spaced circles, thereby dividing the first printing area 10 into a third printing area 30 and a fourth printing area 40. The third printing area comprises multiple non-connected circles (or portions of circles). Furthermore, the size or orientation of the circles can be adjusted according to the needs of the application.

[0066] For example, it can be like Figure 4As shown, a third printing area 30 is selected from the first printing area 10 according to the rule of spaced rhombuses, thereby dividing the first printing area 10 into a third printing area 30 and a fourth printing area 40. The third printing area comprises multiple non-connected rhombuses (or portions of rhombuses). Furthermore, the size or orientation of the rhombuses can be adjusted according to the needs of the application.

[0067] For example, it can be like Figure 5 As shown, a third printing area 30 is selected from the first printing area 10 according to the rule of spaced rectangles, thereby dividing the first printing area 10 into a third printing area 30 and a fourth printing area 40. The third printing area comprises multiple non-connected rectangles (or portions of rectangles). Furthermore, the size or orientation of the rectangles can be adjusted according to the needs of the application. It should be particularly noted that, in this embodiment of the invention, the interlaced distribution of rectangles in different directions can effectively improve the uniformity of the distribution of the specified printing consumables.

[0068] Obviously, the shape of a specific graphic can be achieved in many different ways, or by mixing and matching different shapes. This is a simple variation of the embodiments of the present invention and should be considered within the scope of protection of the present invention.

[0069] In another embodiment of the present invention, the first printing area is processed according to an amplitude modulation dot matrix algorithm to select the third printing area.

[0070] For example, it can be like Figure 6 As shown, the first printing area 10 is processed according to the circular amplitude modulation halftone dot algorithm to divide it into a third printing area 30 and a fourth printing area 40. The third printing area includes multiple disconnected circles (or portions of circles). It should be noted that the size of the halftone dots (i.e., the circles) is determined based on the color information of the image to be printed; that is, the larger the color value, the larger the halftone dot. The specific implementation of the amplitude modulation halftone dot algorithm is existing technology and will not be elaborated upon here.

[0071] For example, it can also be like Figure 7 As shown, the first printing area 10 is processed according to the circular and rhombus amplitude modulation dot algorithm to divide the first printing area 10 into a third printing area 30 and a fourth printing area 40. The third printing area includes multiple disconnected circles / rhombuses (or portions of circles / rhombuses).

[0072] Obviously, other shapes of dots can also be used. The distance between each dot can be adjusted according to implementation needs.

[0073] After dividing the printing area into the third and fourth printing areas, the amount of printing consumables can be set. Specifically, the amount of printing consumables in the third printing area can be set to be non-zero, and the amount of printing consumables in the fourth printing area can be set to zero.

[0074] In one implementation, setting the specified printing material usage in the third printing area to be non-zero includes setting the density of the specified printing material in the third printing area to 100%. Specifically, the density of the specified printing material in the entire third printing area is set to 100%. Setting the amount of specified printing material usage can be based on the image to be printed. For example, if the specified printing material is white ink, a corresponding white color channel is added. The color value of the white color channel of the pixels in the third printing area of ​​the image to be printed can be adjusted to achieve the white ink usage setting. In another implementation, setting the amount of specified printing material usage can be based on the dot data of the image to be printed. By adding dot data corresponding to a white color channel, the dot data corresponding to the third printing area can be set to achieve the white ink usage setting.

[0075] In another embodiment of the present invention, setting the amount of designated printing consumables in the third printing area to be non-zero includes: setting the concentration of the designated printing consumables in the third printing area according to the ink concentration of the third printing area. Further, the higher the ink concentration, the higher the concentration of the designated printing consumables is set. The ink concentration can be characterized by the color value of any one color channel, or by the sum of the color values ​​of multiple color channels.

[0076] like Figure 8 As shown, in another embodiment of the present invention, in step S40, setting the specified printing consumable usage in the third printing area to be non-zero includes:

[0077] S41: Perform halftone processing on the image to be printed to obtain halftone data;

[0078] S42: Set the specified printing consumable usage for the third printing area based on the network data.

[0079] Specifically, halftone processing is performed on the image to be printed to obtain dot data, and then the amount of printing consumables for the third printing area is set according to this dot data. For example, keeping the dot data corresponding to the third printing area in the image to be printed unchanged, other dot data (i.e., the dot data corresponding to the fourth printing area) are filled with 0 or 00 as the dot data for the white color channel. In another embodiment of the invention, when the dot data corresponding to the fourth printing area is filled with 0 or 00, the ink output represented by the dot data corresponding to the third printing area can be modified. Of course, it is also possible to add dot data corresponding to a specified printing consumable, and then fill the dot data corresponding to the specified printing consumable according to the dot data corresponding to the third printing area in the dot data corresponding to the image to be printed.

[0080] For easier understanding, please refer to Figure 9 This is a schematic diagram of an image to be printed after halftone processing, provided by an embodiment of the present invention.

[0081] The third printing area is as follows Figure 10 As shown, select according to the rule of spaced rectangles, and then as... Figure 11 As shown, the point data corresponding to the third printing area remains unchanged, while the point data corresponding to the fourth printing area is filled with 0.

[0082] After setting the specified amount of printing consumables, printing can begin. Specifically, the specified printing consumables are used to print the first printing area that needs to be covered, forming the base layer. The specified printing consumables are one or more of white ink, hot melt powder, and processing fluid.

[0083] In the subsequent printing process, colored inks can be printed on the base layer, which not only ensures printing quality but also improves the breathability of the fabric.

[0084] Please see Figure 12 This invention provides a printing control device for improving the breathability of fabrics, comprising:

[0085] The image acquisition module is used to acquire the image to be printed;

[0086] The region segmentation module is used to divide the image to be printed into a first printing region and a second printing region; wherein, the first printing region is the region that needs to be covered with a specified printing material, and the second printing region is the region that does not need to be covered with a specified printing material.

[0087] The region selection module selects a third printing region from the first printing region; wherein, the third printing region includes multiple non-connected regions, the area of ​​the third printing region is smaller than that of the first printing region, and the region in the first printing region other than the third printing region is denoted as the fourth printing region;
