Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, and in particular to an image inkjet printing method, apparatus, electronic device, and storage medium. Background Technology

[0002] An inkjet printer is an automated device used to print images on printed circuit boards. The images printed on a printed circuit board can be broadly divided into large areas of concentrated white ink and characters. Since characters are generally small and need to be clearly displayed after printing, it is necessary to control the amount of ink ejected from the characters to avoid blurry characters caused by ink flow.

[0003] Existing technologies generally separate inkjet graphics into white ink block graphics and character graphics by setting thresholds, for example, based on the morphological characteristics of each graphic, such as width, height, or the largest inscribed circle. Then, the number of pixels in the separated white ink block graphics and character graphics is processed separately to control the amount of ink used for character printing.

[0004] However, using the existing separation method requires adjusting different thresholds for different graphics, and it can cause problems such as inaccurate separation of white ink blocks and characters, resulting in color differences or unclear characters after printing. Summary of the Invention

[0005] This invention provides an image printing method, apparatus, electronic device, and storage medium, which can accurately separate small character graphics in the printed image, solve the problem of unclear small character printing, and effectively improve the clarity of the printed image.

[0009] According to the preset sampling rules, the first and second printed images are sampled.

[0010] The first and second printed images, after point sampling, are merged to obtain a merged printed image, which is then loaded into the printing process for printing.

[0011] According to another aspect of the present invention, an image printing apparatus is provided, comprising:

[0012] The target corrosion radius value determination module is used to analyze the current inkjet image and determine the target corrosion radius value that matches the current inkjet image based on the analysis results.

[0020] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the image printing method according to any embodiment of the present invention.

[0021] The technical solution of this invention, by etching and separating the current inkjet image, performing dot sampling on each image after etching and separating, and merging the dot-sampling images before printing, can accurately separate white ink block graphics and small character graphics in the inkjet image, solving the problem of inaccurate separation of small character graphics. It can control the amount of ink sprayed on each graphic in the inkjet image, especially the amount of ink sprayed on smaller characters, avoiding ink overflow at the smaller characters after printing, thereby ensuring that the smaller characters in the printed image can be clearly displayed, effectively improving the clarity of the printed image.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Example 1

[0032] Figure 1 This is a flowchart of an image printing method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where small characters in the printed image are clearly displayed after etching and separating the current image to be printed. This method can be executed by an image printing device, which can be implemented in hardware and / or software. The image printing device can be configured in a computer or processor with image processing capabilities. Figure 1 As shown, the method includes:

[0033] S110. Analyze the current inkjet image and determine the target corrosion radius value that matches the current inkjet image based on the analysis results.

[0034] Optionally, the current printed image can be understood as the target image that the user needs to print. Common printed images can be roughly divided into large areas of white ink blocks and character graphics.

[0035] Figure 2 This is a schematic diagram illustrating the etching separation and merging effects of an optional inkjet-printed image. Figure 2 In the current printed image shown, the black dots are a type of white ink block graphic, and the continuous numbers or letters are an optional character graphic. Figure 2 The lower right corner of the current printed image shows an image consisting of a black background and white characters. During the printing process, the ink may spread to the white characters due to the larger ink volume at the edges of the black background and white characters, thus affecting the clarity of the characters.

[0036] To address the aforementioned problems, this invention creatively proposes a method of separating the printed image into two complementary images by etching the printed image according to the etching radius value. One image essentially contains the white ink block graphic in the printed image, and the other image essentially contains the character graphic in the printed image. By controlling the pixels of the two images separately, the amount of ink at the edges of the characters can be reduced.

[0037] Optionally, the purpose of etching the current printed image is to separate the white ink block graphic and the character graphic. Therefore, the target etching radius value can be determined based on the pixel value of the character line width.

[0038] Optionally, the target separation threshold can be equal to or slightly greater than the pixel value of the character line width. Of course, the target erosion radius does not have to rely on the line width of the character graphic, and can be considered from other optional aspects, as long as the final target erosion radius can accurately separate the white oil block graphic and the character graphic.

[0039] Optionally, the target corrosion radius value can also be predetermined based on the experience of the technicians.

[0040] S120. Based on the target corrosion radius value, perform corrosion separation on the current inkjet image to obtain the first inkjet image and the second inkjet image.

[0041] The first and second inkjet images are complementary etched images.

[0042] The first printed image may include the pixel information remaining after the current printed image is etched, and the second printed image may include the pixel information that has been etched away in the current printed image.

[0043] Figure 2 The document also shows an example of an optional first printed image and an example of an optional second printed image. (Through...) Figure 2 As shown in the example image, the inner and outer edges of each graphic in the current printed image can be etched according to the target etching radius, and the remaining part after etching is the first printed image. Since the second printed image is the complementary image of the first printed image, the second printed image containing all the etched parts can be directly obtained based on the current printed image and the first printed image.

[0044] Through the embodiments of the present invention and Figure 2 As can be seen from the examples, the separation method proposed in this invention can accurately separate the white oil block graphic from the character graphic, solving the problem of inaccurate separation in the prior art.

[0045] S130. According to the preset sampling rules, perform sampling processing on the first printed image and the second printed image.

[0046] It is understandable that the purpose of dot sampling in the printed image is to reduce the number of pixels in the image. Generally, the amount of ink sprayed during the printing process is determined by the number of pixels in the image. By reducing the number of pixels, the amount of ink sprayed can be reduced.

[0047] Optionally, the proportion of dots sampled in the first printed image can be smaller than that in the second printed image. For example, the proportion of dots sampled in the first printed image can be 10%, and the proportion of dots sampled in the second printed image can be 30%. Consequently, the graphics contained in the second printed image have a relatively smaller ink volume during printing, thereby effectively controlling the ink volume at the edges of the character graphics.

[0048] Optionally, the sampling process can be performed by uniformly sampling points from each graphic, or by sampling points from a specified part according to the actual printing requirements, without limiting the specific sampling rules.

[0049] S140. The first inkjet image and the second inkjet image after the sampling process are merged to obtain a merged inkjet image, and the merged inkjet image is loaded into the inkjet process for inkjet processing.

[0050] Optionally, merging the printed images can be understood as merging the pixels of the first printed image after sampling with those of the second printed image according to the specified position information or coordinate information to obtain the image.

[0051] Figure 2 The diagram also shows a schematic of the merged printed image obtained by combining the first and second printed images after dot-sampling processing. Figure 2 As shown, in the merged inkjet image, the portion merged from the second inkjet image is significantly lighter in color than the rest. Understandably, in actual pixel sampling, these lighter-colored portions will be sampled at a higher rate.

[0052] The technical solution of this invention, by etching and separating the current inkjet image, performing dot sampling on each image after etching and separating, and merging the dot-sampling images before printing, can accurately separate white ink block graphics and small character graphics in the inkjet image, solving the problem of inaccurate separation of small character graphics. It can control the amount of ink sprayed on each graphic in the inkjet image, especially the amount of ink sprayed on smaller characters, avoiding ink overflow at the smaller characters after printing, thereby ensuring that the smaller characters in the printed image can be clearly displayed, effectively improving the clarity of the printed image.

[0053] Example 2

[0054] Figure 3This is a flowchart of an image printing method provided in Embodiment 2 of the present invention. This embodiment specifically describes the image printing method based on the above embodiments. Figure 3 As shown, the method includes:

[0055] S210. Identify multiple character graphics in the current printed image and obtain the pixel information corresponding to each character graphic.

[0056] Optionally, the pixel information corresponding to the character graphic may include the pixel value of the character line width.

[0057] S220. Based on the pixel information corresponding to each character graphic, select the smallest character in the current inkjet image and obtain the target pixel value that matches the smallest character.

[0058] Optionally, the smallest character is not necessarily the character with the smallest length and width. It can also be the character with the smallest pixel value of the character line width. In this case, the target pixel value of the smallest character can be understood as the pixel value of the smallest character line width.

[0059] S230. Determine the target transition threshold that matches the target pixel value, and determine the target corrosion radius that matches the current inkjet image based on the target pixel value and the target transition threshold.

[0060] Understandably, the target transition threshold can be determined based on the target pixel value. For example, when the target pixel value is 2 pixels, the target transition threshold that matches it can be 1 pixel, and the target erosion radius can be the sum of the target pixel value and the target transition threshold, i.e., 3 pixels.

[0061] Optionally, the target transition threshold is generally a small value. Of course, it is also possible not to set a target transition threshold, and it is only necessary to confirm that the target corrosion radius can accurately separate the white oil block graphic and the character graphic.

[0062] The purpose of this setting is to determine the target erosion radius by adding a target transition threshold to the target pixel value, thereby avoiding the situation where the overlapping lines in the character graphic cannot be accurately eroded and separated.

[0063] S240. Based on the target corrosion radius value, perform corrosion separation on the current inkjet image to obtain the first inkjet image and the second inkjet image.

[0064] Specifically, based on the target corrosion radius value, corrosion separation is performed on the current printed image to obtain a first printed image and a second printed image, including:

[0065] In the current printed image, identify multiple first continuous patterns and identify the inner and outer edges of each first continuous pattern;

[0066] Each first continuous graphic is etched and separated from its inner and outer edges according to the target etching radius value, and a first inkjet image is generated based on the remaining pixel information after etching and separating each first continuous graphic.

[0067] Delete all pixel information contained in the first printed image from the current printed image, and after deleting the pixel information, generate the second printed image based on the remaining pixel information in the current printed image.

[0068] Optionally, in the embodiments described in this invention, the first continuous graphic can represent a continuous graphic obtained from the inkjet image, and the second continuous graphic can represent a continuous graphic in the first inkjet image after dot sampling processing. The terms "first" and "second" are used here only to distinguish the continuous graphics extracted from each image. A continuous graphic can be understood as one in which the outermost edge pixels can form a closed shape.

[0069] S250: Obtain pixel information from the current printed image, the first printed image, and the second printed image, respectively.

[0070] The pixel information in the image may include, but is not limited to, pixel location information, coordinate information, etc.

[0071] S260. Based on the pixel information in the current printed image, the first printed image, and the second printed image, determine whether the first printed image and the second printed image include all the pixel information in the current printed image; if yes, execute S270; if no, execute S280.

[0072] Understandably, this step is to determine whether the corrosion separation process is successful. If the first and second printed images include all the pixel information in the current printed image, it means that no information was lost during the corrosion separation process.

[0073] S270. When it is determined that the first and second printed images include all pixel information in the current printed image, perform point sampling processing on the first and second printed images according to the preset point sampling rules; execute S290.

[0074] The process involves sampling points from both the first and second printed images according to preset sampling rules, including:

[0075] According to the preset sampling rules, the first sampling ratio corresponding to the first printed image and the second sampling ratio corresponding to the second printed image are determined.

[0076] Based on the first sampling ratio and the second sampling ratio, sampling processing is performed on the first printed image and the second printed image respectively.

[0077] S280, Generate separation failure information and send it to the user.

[0078] S290. Obtain the first inkjet image after dot sampling processing, and identify multiple second continuous patterns in the first inkjet image after dot sampling processing.

[0079] S2100: Obtain the pixel information of each second continuous graphic, and determine whether there is a risk area of ​​exposed bottom in each second continuous graphic based on the pixel information of each second continuous graphic; if yes, execute S2110; if no, execute S2120.

[0080] Understandably, printing requirements for white ink block graphics may include prohibiting the exposure of the background. Therefore, in the first printed image after dot sampling, the risk of background exposure can be determined by analyzing the pixel distribution information, thereby avoiding the occurrence of non-compliant printed images.

[0081] S2110. Fill the exposed area with pixels according to the preset fill pixel value, and at the same time generate an exposed risk warning and send it to the user.

[0082] S2120. When it is determined that there is no exposed risk area in the second continuous pattern, the first inkjet image and the second inkjet image after sampling are merged to obtain a merged inkjet image; execute S2130.

[0083] S2130. Compare the merged inkjet image with the current inkjet image to determine if there is any missing information in the merged inkjet image; if yes, proceed to S2140; if no, proceed to S2150.

[0084] Understandably, before printing merged images, the merged images can be checked to avoid errors during the merging process, which could result in the printing of incorrect images.

[0085] S2140, Generate a missing information prompt and send it to the user.

[0086] S2150. When it is determined that there is no missing information in the merged inkjet image, the merged inkjet image is loaded into the inkjet process for inkjet processing.

[0087] The technical solution of this invention, by adding a target transition threshold to the target pixel value to determine the target corrosion radius, can avoid the situation where the overlapping lines in the character graphic cannot be accurately corroded and separated. By detecting the pixel information of the first and second printed images, detecting the risk of exposure after point sampling, and detecting the integrity of the merged printed images, the problem of poor printing effect caused by image processing errors can be avoided, thereby reducing resource waste and printing costs to a certain extent.
