[0002] During the character inkjet printing process of a printed circuit board (PCB) by an inkjet printer, the following process is usually adopted: a raster image processor can read an original compressed file, parse the character layer therein to generate a vector map, rasterize it into a BMP (Bitmap) bitmap, and perform overall dot extraction processing on the BMP bitmap to form a new image to be printed. The inkjet printing device loads the new image to be printed and performs inkjet printing on the PCB board.

[0003] Since during the dot extraction process, a fixed dot extraction ratio is used for the entire bitmap for dot extraction, after the inkjet printing is completed, the inkjet printing thickness of some patterns does not meet the standard, resulting in inkjet printing quality problems such as bottom exposure or stripes; the inkjet printing thickness of some patterns is too thick, resulting in problems such as blurred pattern edges and wasted ink.

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] In the related art, in the character spraying process of the PCB board, the character spraying process is generally as follows: software with a Raster Image Processor (RIP) reads a tgz compressed file in ODB ++ format → the software with RIP parses the character layer to generate a vector graph → rasterizes to generate a BMP bitmap → performs overall dot extraction processing on the BMP graph → the spraying device loads the BMP graph → sprays on the PCB board.

[0018] Among them, in the original ODB ++ format data, there is a lack of marking information for various patterns. After rasterizing the vector graph into a BMP graph, as Figure 9 shown, the patterns in the BMP graph can only be controlled for dot extraction in a unified manner as a whole, that is, a fixed dot extraction ratio is selected for all patterns. For example, dot extraction is performed at a fixed dot extraction ratio of 50% uniformly, and the spraying thickness of the patterns is the same. The to-be-sprayed image 60 with this single dot extraction ratio cannot set the dot extraction ratio for the patterns that need to be improved separately. This will cause the spraying thickness of some patterns on the PCB board after spraying to not meet the standard, resulting in spraying quality problems such as exposed bottom and stripes; some patterns also have quality problems such as over-thick spraying and relatively blurred spraying edges.

[0019] In view of this, the present application proposes an image spraying method, which can solve the above technical problems and make the spraying quality of the patterns on the PCB board after spraying better.

[0020] Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0021] As Figure 1 shown, an embodiment of the present invention proposes an image spraying method, including the following steps S100 to S400: Step S100 in the present application includes: parsing the current spraying image and selecting different types of patterns according to the parsing result, and the unselected patterns are the remaining patterns.

[0022] The current printed image in this application may contain various types of information, such as pattern information, thickness information, grayscale value information, etc. In this application, computer-aided manufacturing software is used to specifically analyze the pattern information of the current printed image in the original ODB++ data, and different types of patterns and remaining patterns are determined.

[0023] In some embodiments, as Figure 2 shown, step S100 includes step S110: performing a print thickness analysis on the current printed image, selecting different types of patterns according to different thickness requirements, and the unselected patterns are the remaining patterns with the same thickness. That is, in these embodiments, computer-aided manufacturing software is used to specifically analyze the thickness information and corresponding pattern information of the current printed image in the original ODB++ data, and the patterns corresponding to different print thickness requirements are determined, so that the patterns of the same type can be divided according to the specific requirements of the print thickness, which is convenient for subsequent targeted marking of patterns with different print thickness requirements.

[0024] In a specific embodiment, RIP software can be used to analyze the information of the image, and RIP software can also convert vector graphics into raster bitmap data, which is convenient for the PCB character printer to accurately output and print.

[0025] Continuing to refer to Figure 1 , step S200 in this application includes: marking and differentiating different types of patterns and remaining patterns to form multiple printed images. That is, by adopting step S200, the current printed image in this application can be separated and rasterized into multiple printed images of the same size. For example, the current printed image can be marked and differentiated according to different types of patterns and remaining patterns respectively to form 4 printed images, which are respectively Figure 5 the first printed image 51 shown in Figure 6 the second printed image 52 shown in Figure 7 the third printed image 53 shown in Figure 8 the fourth printed image 54 shown in . That is to say, for three types of patterns and remaining patterns, four printed images are finally formed.

[0026] It can be understood that by marking and differentiating different types of patterns and remaining patterns in this application, different patterns to be printed can be distinguished.

[0027] In some embodiments, as Figure 3 shown, marking and differentiating different types of patterns and remaining patterns to form multiple printed images includes the following steps S210 and step S220.

[0028] Step S210: Perform string tagging on different types of patterns and the remaining patterns to form multiple inkjet printing images with string tags. That is to say, in this application, through computer-aided manufacturing software, the attribute operation text can be added and defined as: tagging the patterns. Thus, the corresponding naming of the patterns can be found in the program, which is convenient for separating different inkjet printing images and also convenient for performing dot extraction processing on different inkjet printing images in subsequent steps.

[0029] For example, the pattern of the laser QR code can be tagged with the string "mark_layer1"; for another example, the pattern of the white oil block can be tagged with the string "mark_layer2"; for yet another example, the text pattern can be tagged with the string "mark_layer3"; or, for example, the grid pattern can be tagged with the string "mark_layer4"; or, for example, the stripe pattern can be tagged with the string "mark_layer5"; while other patterns without added attributes are tagged as the remaining patterns. Thus, different patterns of the current inkjet printing image in this application can correspond to different string tags.

[0030] In some further embodiments, the patterns corresponding to this application after string tagging also correspond to different thicknesses, so that each pattern has its own required thickness after final inkjet printing.

[0031] Step S220: Perform color tagging on different types of patterns and the remaining patterns to form multiple inkjet printing images with color tags. That is to say, in this application, through computer-aided manufacturing software, different types of patterns and the remaining patterns that have been string-tagged can be tagged with different colors respectively. It is convenient to separate the patterns corresponding to different colors from the current inkjet printing image and facilitate subsequent differentiation of inkjet printing graphics that require different dot extraction ratios.

[0032] In some embodiments, the color tags and the string tags have a one-to-one mapping relationship, so that different patterns are easy to distinguish and each pattern has multiple corresponding pieces of information.

[0033] For example, "mark_layer1", "mark_layer2", "mark_layer3", "mark_layer4", "mark_layer5" and the remaining patterns are respectively defined as red, green, blue, yellow, purple, orange, so that patterns tagged with different strings can all be tagged with different colors, and thus patterns tagged with different strings can have a one-to-one mapping relationship with the colors.

[0034] In some embodiments, as Figure 3 shown, performing tagging and differentiation on different types of patterns and the remaining patterns to form multiple inkjet printing images further includes the following step S230: Step S230: Rasterize the marked patterns of different types and the remaining patterns into images of the same size, which facilitates subsequent synthesis and also facilitates the formation of a printable BMP image with rich preset information.

[0035] Then, through Step S210, Step S220, and Step S230, according to the added string attributes, the RIP software can perform precise screening based on the marked string attributes, mark different colors inside the RIP software, and in the rendering engine frame buffer, filter out the marked patterns through the mapping table of attribute names and colors, and rasterize them into BMP images of the same size respectively, thereby generating multiple BMP-format inkjet printing images. In some specific embodiments, the inkjet printing image corresponding to the remaining pattern can be named Job.bmp.

[0036] Continue to refer to Figure 1 , Step S300 in this application includes: setting multiple dot extraction ratios for multiple inkjet printing images respectively according to the preset inkjet printing thickness, and performing dot extraction processing. That is to say, in this application, each of the multiple inkjet printing images can preset a thickness information, and perform different dot extraction processing according to its respective thickness information.

[0037] It can be understood that the purpose of dot extraction for the inkjet printing image is to reduce the number of pixel points in the image. Generally, in the inkjet printing process, the inkjet volume is determined according to the pixel points in the image. By reducing the number of pixel points, the inkjet volume can be reduced.

[0038] In this application, as Figure 3 shown, Step S300 further includes Step S310: preset a different dot extraction ratio for each inkjet printing image with a different inkjet printing thickness, and perform dot extraction processing respectively. That is to say, there is a one-to-one mapping relationship between the inkjet printing thickness and the dot extraction ratio of the multiple inkjet printing images in these examples.

[0039] For example, in some embodiments, the dot extraction ratio for mark_layer1 can be 25%, the dot extraction ratio for mark_layer2 can be 35%, the dot extraction ratio for mark_layer3 can be 50%, the dot extraction ratio for mark_layer4 can be 60%, the dot extraction ratio for mark_layer5 can be 70%, the dot extraction ratio for the remaining pattern can be 80%, etc., so as to form patterns with different inkjet printing thicknesses.

[0040] In some embodiments, the thicker the printing thickness of the printed image, the lower the sampling ratio of the printed image, so that the printing thickness of the thicker printing image is low in sampling ratio, while obtaining the required printing thickness, without causing quality problems such as bottom exposure and stripes, and saving ink; preventing the edge of the printed image from being blurred due to excessive ink. It also makes the printing thickness of the thinner printing image have a high sampling ratio, while obtaining the required printing thickness, and obtaining a printed image with clear lines and no blurred edges.

[0041] Continue to refer to Figure 1 In this application, step S400 includes: merging each printing image after the sampling process to obtain Figure 4 The merged printing image 50 shown in the figure is loaded into the printing process for printing.

[0042] As can be seen from the above, the image printing method proposed in the present invention can analyze and select different types of patterns on the image to be printed and mark them, set the required sampling ratio and sample the points for different types of patterns according to the preset printing thickness, and synthesize the new merged printing image 50 based on the printing image after the sampling process, and print the merged printing image 50, so as to achieve the selected different types of patterns to obtain the required printing thickness, improve the problems of stripes, exposed bottom, blurred edges, etc. formed on the image after printing, and improve the printing quality of the image.

[0043] The following describes the specific steps of an image printing method in a specific embodiment. Figure 1 As shown, the specific steps are as follows: Step S100 includes: analyzing the current printing image, and selecting different types of patterns according to the analysis results, and the unselected patterns are the remaining patterns.

[0044] Step S200 includes: marking and distinguishing different types of patterns and remaining patterns to form a plurality of printed images.

[0045] Step S300 includes: setting a plurality of sampling ratios for a plurality of printing images according to a preset printing thickness, and performing sampling processing.

[0046] Step S400 includes: merging each printing image after the sampling process to obtain Figure 4 The merged printing image 50 shown in the figure is loaded into the printing process for printing.

[0047] The following describes the specific steps of an image printing method in another specific embodiment. Figure 2 As shown, the specific steps are as follows: Step S110: Analyze the printing thickness of the current printed image, select different types of patterns according to different thickness requirements, and the unselected patterns are the remaining patterns with the same thickness.

[0048] Step S200 includes: Marking and differentiating different types of patterns and the remaining patterns to form multiple printed images.

[0049] Step S300 includes: Setting multiple sampling ratios for each of the multiple printed images according to the preset printing thickness, and performing sampling processing.

[0050] Step S400 includes: Merging the sampled processed printed images to obtain Figure 4 the merged printed image 50 shown in, and loading the merged printed image 50 into the printing process for printing.

[0051] The following describes the specific steps of the image printing method in another specific embodiment. As Figure 3 shown, it includes the following specific steps: Step S100: Analyze the current printed image, and select different types of patterns according to the analysis results. The unselected patterns are the remaining patterns.

[0052] Step S210: Perform string marking on different types of patterns and the remaining patterns to form multiple printed images with string markings. Taking four patterns as an example, specifically, the first pattern is marked with the string mark mark_layer1, the second pattern is marked with the string mark mark_layer2, the third pattern is marked with the string mark mark_layer3, and the pattern without additional string marking is marked as the remaining pattern.

[0053] Step S220: Perform color marking on different types of patterns and the remaining patterns to form multiple printed images with color markings. Specifically, the first pattern corresponding to mark_layer1 is marked as red, the second pattern corresponding to mark_layer2 is marked as green, the third pattern corresponding to mark_layer3 is marked as blue, and the remaining pattern is marked as yellow.

[0054] Step S230: Rasterize the marked different types of patterns and the remaining patterns into images of the same size. Specifically, the first printed image 51, the second printed image 52, the third printed image 53, and the fourth printed image 54 with four thicknesses, four colors, and four string markings are respectively formed. In this application, for the four printed images, a color palette can be specified during printing. When the gray value is 0, it is defined as black, and when the gray value is 255, it is defined as white. That is to say, the black part shown in the figure is the non-printing part, and the white part shown in the figure is the part that needs to be printed during printing.

[0055] Step S310: Preset a different sampling ratio for each printing image with a different printing thickness, and perform sampling processing separately. Specifically, the sampling ratio for the first printing image 51 in Figure 5 is 25%, the sampling ratio for the second printing image 52 in Figure 6 is 60%, the sampling ratio for the third printing image 53 in Figure 7 is 70%, and the sampling ratio for the fourth printing image 54 in Figure 8 is 50%.

[0056] Step S400 includes: Merging the sampled printing images. When merging, the thickness information, string marker information of the pattern, and color marker information of each image are retained, and the merged printing image 50 shown in Figure 4 is obtained. The merged printing image 50 is loaded into the printing process for printing. For the merged printing image 50, the black part shown in the figure is the non-printing part, and the white part shown in the figure is the part to be printed during printing.

[0057] Then, in the present application, different marks can be added to identify and perform targeted sampling processing on patterns in multiple regions with different quantities, so that local sampling can be performed on any number of regions, solving various printing quality problems caused by the same printing thickness and single sampling ratio when different patterns need to be printed on the PCB board.

[0058] It can be understood that compared with the to-be-printed image 60 with a single sampling ratio shown in Figure 9 , for the four patterns included in the merged printing image 50 of the present application, corresponding different sampling processing has been performed according to different thicknesses and marks, so as to realize different sampling processing for selected different types of patterns during the printing process, and the quality of the PCB printing image obtained during printing is better, effectively improving image quality problems such as stripes, exposed substrate, and blurred edges that may occur during the printing process.

[0059] The image printing device 100 of the present invention will be described below.

[0060] As shown in Figure 10 , the image printing device 100 proposed by the present invention includes: a parsing module 10, a marking module 20, a sampling processing module 30, and an image printing module 40.

[0061] Among them, the parsing module 10 is used to parse the current printing image, select different types of patterns according to the parsing result, and the unselected patterns are the remaining patterns. The characteristics of the current printing image are as described above and will not be elaborated here. In this application, computer-aided manufacturing software is used to specifically parse the pattern information of the current printing image in the original ODB++ data, and determine different types of patterns and the remaining patterns.

[0062] The marking module 20 is used to mark and distinguish the selected different types of patterns and the remaining patterns to form multiple printing images. When marking, the computer-aided manufacturing software can be used to add attribute operation text definitions, such as adding corresponding strings. The computer-aided manufacturing software can also be used to add different color indexes, such as marking different colors; or different colors can be marked for different types of patterns and the remaining patterns with string markings respectively.

[0063] The dot extraction processing module 30 is used to set multiple dot extraction ratios for each of the multiple printing images according to the preset printing thickness and perform dot extraction processing. That is to say, in this application, each of the multiple printing images can preset a thickness information, and different dot extraction processing can be performed according to their respective thickness information. For example, there is a one-to-one mapping relationship between the printing thickness and the dot extraction ratio of the multiple printing images.

[0064] The image printing module 40 is used to merge the dot extraction processed printing images to obtain a merged printing image 50, and load the merged printing image 50 into the printing process for printing.

[0065] As can be seen from the above, the image printing device 100 proposed by the present invention parses and selects different types of patterns on the image to be printed and marks them, sets the required dot extraction ratios for different types of patterns according to the preset printing thickness and performs dot extraction, and performs printing on the merged printing image 50 synthesized after dot extraction processing, so as to enable the selected different types of patterns to obtain their respective required printing thicknesses, improve problems such as stripes, exposed bottoms, and blurred edges formed in the printed image, and enhance the printing quality of the image.

[0066] The following describes the electronic device 1000 of the present invention.

[0069] As can be seen from the above, for the electronic device 1000 proposed by the present invention, by using the memory 200 to store computer program instructions and using the processor 300 to call the computer program instructions, the computer program instructions are made to execute the image spraying method. During the spraying process, different types of patterns on the selected image to be sprayed are parsed and marked, the required dot extraction ratio is set for different types of patterns according to the preset spraying thickness and dot extraction is performed, and based on the new combined spraying image 50 synthesized after dot extraction processing, the combined spraying image 50 is sprayed, so as to enable different types of patterns to obtain their respective required spraying thicknesses, improve problems such as stripes, exposed substrate, and edge blurring formed in the image after spraying, and enhance the spraying quality of the image.

[0070] The computer-readable storage medium of the present invention is described below.
