[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0033] In related technologies, the character printing process on PCB boards generally involves the following steps: software with a raster image processor (RIP) reads a .tgz compressed file in ODB++ format → software with RIP parses the character layers to generate a vector graphic → rasterizes the graphic to generate a BMP bitmap → performs overall pixel sampling on the BMP graphic → the printing equipment loads the BMP graphic → printing is performed on the PCB board.

[0034] The original ODB++ format data lacked marking information for various patterns. After rasterizing the vector graphics into BMP images, such as... Figure 9 As shown, the patterns in the BMP image can only be controlled by sampling in a uniform manner, that is, a fixed sampling ratio is used for all patterns, such as a fixed sampling ratio of 50%. This results in a consistent printing thickness for all patterns. However, this single sampling ratio for the image to be printed does not allow for individual sampling ratio settings for patterns that need improvement. This will lead to some patterns on the printed PCB board having insufficient printing thickness, resulting in printing quality issues such as exposed substrate and streaks; while other patterns will have excessively thick printing and blurry printing edges.

[0035] In view of this, this application proposes an image inkjet printing method that can improve the above-mentioned technical problems and make the inkjet printing quality of the pattern on the PCB board after inkjet printing better.

[0036] Where there is no conflict, the following embodiments and features can be combined with each other.

[0037] As Figure 1 shown, embodiments of the present application propose an image jet printing method, comprising the following steps S100 to S400:

[0038] Step S100 in the present application comprises: analyzing the current jet printing image, and selecting different types of patterns according to the analysis result, and the unselected patterns are the remaining patterns.

[0039] The current jet printing image in the present application can contain various information, such as pattern information, thickness information, gray value information, etc. In the present application, the computer-aided manufacturing software is used to analyze the pattern information of the current jet printing image in the original ODB++ data, and determine different types of patterns and the remaining patterns.

[0040] In some embodiments, as Figure 2 shown, step S100 comprises step S110: analyzing the jet printing thickness of the current jet printing 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, the computer-aided manufacturing software is used to analyze the thickness information and the corresponding pattern information of the current jet printing image in the original ODB++ data, and determine the patterns corresponding to different jet printing thickness requirements, so that the same type of patterns can be divided according to the specific requirements of the jet printing thickness, facilitating subsequent targeted marking of patterns with different jet printing thickness requirements.

[0041] In specific embodiments, the information of the image can be analyzed by using the RIP software, and the RIP software can also convert vector graphics into raster bitmap data, facilitating the accurate output and printing of the PCB character jet printing machine.

[0042] Continuing to refer to Figure 1 , step S200 in the present application comprises: marking and distinguishing different types of patterns and the remaining patterns to form multiple jet printing images. That is, by using step S200, the current jet printing image in the present application can be separated and rasterized into multiple jet printing images with the same size. For example, the current jet printing image can be marked and distinguished according to different types of patterns and the remaining patterns to form four jet printing images, which are respectively Figure 5 the first jet printing image 51 shown in Figure 6 the second jet printing image 52 shown in Figure 7 the third jet printing image 53 shown in Figure 8 the fourth jet printing image 54 shown in. That is, for three types of patterns and the remaining patterns, four jet printing images are finally formed.

[0043] It can be understood that the present application can distinguish different patterns to be sprayed by marking and distinguishing different types of patterns and residual patterns.

[0044] In some embodiments, as Figure 3 shown, marking and distinguishing different types of patterns and residual patterns to form a plurality of spray images includes the following steps S210 and S220.

[0045] Step S210: string marking of different types of patterns and residual patterns to form a plurality of spray images with string marking. That is, in the present application, the attribute operation text can be added by computer aided manufacturing software to mark the patterns. Thus, the corresponding name of the pattern can be found in the program, which facilitates the separation of different spray images and facilitates the dot extraction processing of different spray images in subsequent steps.

[0046] For example, the pattern of the laser two-dimensional code can be marked as a string of mark_layer1; for example, the pattern of white oil block can be marked as a string of mark_layer2; for example, the pattern of text can be marked as a string of mark_layer3; for example, the pattern of grid can be marked as a string of mark_layer4; for example, the pattern of stripe can be marked as a string of mark_layer5; and other patterns without added attributes are marked as residual patterns. Thus, different patterns of the current spray image in the present application correspond to different string markings.

[0047] In some further embodiments, the patterns marked by the string in the present application also correspond to different thicknesses, so that each type of pattern has its own required thickness after final spraying.

[0048] Step S220, color marking of different types of patterns and residual patterns to form a plurality of spray images with color marking. That is, in the present application, different colors can be marked on different types of patterns and residual patterns marked by string by computer aided manufacturing software. This facilitates the separation of patterns corresponding to different colors from the current spray image, and facilitates the subsequent differentiation of spray patterns requiring different dot extraction ratios.

[0049] In some embodiments, the color marking and the string marking are in one-to-one mapping relationship, so that different patterns are easily distinguished and each type of pattern has multiple corresponding information.

[0050] For example, mark_layer1, mark_layer2, mark_layer3, mark_layer4, mark_layer5 and the remaining pattern are defined as red, green, blue, yellow, purple, orange respectively, so that the patterns marked by different strings can be marked in different colors, so that the patterns marked by different strings can be in one-to-one mapping relationship with the colors.

[0051] In some embodiments, as shown in Figure 3 marking and distinguishing different types of patterns and the remaining pattern to form a plurality of printing images further includes the following step S230:

[0052] Step S230, rasterizing the marked different types of patterns and the remaining pattern into images of the same size. Thus, it is convenient to perform subsequent synthesis, and it is also convenient to form a printable BMP image with rich preset information.

[0053] Then, through steps S210, S220 and S230, according to the added string attribute, the RIP software can accurately filter through the marked string attribute, mark different colors in the RIP software, filter out the marked patterns through the mapping table of attribute name and color in the rendering engine frame buffer, and rasterize them into BMP images of the same size respectively, so as to generate a plurality of BMP format printing images. In some specific embodiments, the printing image corresponding to the remaining pattern can be named as Job.bmp.

[0054] Continuing to refer to Figure 1 , step S300 in the present application includes: setting a plurality of dot extraction ratios for a plurality of printing images according to a preset printing thickness, and performing dot extraction processing. That is, in the present application, each of the plurality of printing images can be preset with a thickness information, and different dot extraction processing can be performed according to the respective thickness information.

[0055] It can be understood that the purpose of dot extraction for printing images is to reduce the number of pixels in the image. Generally, in the printing process, the amount of ink is determined according to the number of pixels in the image. By reducing the number of pixels, the amount of ink can be reduced.

[0056] In the present application, as shown in Figure 3 , step S300 further includes step S310: setting a different dot extraction ratio for each printing image with different printing thickness, and performing dot extraction processing respectively. That is, the printing thickness and the dot extraction ratio of the plurality of printing images in these examples are in one-to-one mapping relationship.

[0057] For example, in some embodiments, the dot extraction ratio of mark_layer1 can be 25%, the dot extraction ratio of mark_layer2 can be 35%, the dot extraction ratio of mark_layer3 can be 50%, the dot extraction ratio of mark_layer4 can be 60%, the dot extraction ratio of mark_layer5 can be 70%, and the dot extraction ratio of the remaining pattern can be 80%, so as to form patterns with different inkjet thicknesses.

[0058] In some embodiments, the thicker the inkjet thickness of the inkjet image, the lower the dot extraction ratio of the inkjet image, so that the inkjet image with a relatively thick inkjet thickness has a low dot extraction ratio, thereby obtaining the required inkjet thickness without quality problems such as exposure and stripes, and saving ink; prevent the image from being blurred due to excessive ink at the edge of the pattern of the inkjet image. Also, the inkjet image with a relatively thin inkjet thickness has a high dot extraction ratio, thereby obtaining the required inkjet thickness and obtaining a clear inkjet image with clear lines and no blurred edges.

[0059] With reference to the foregoing Figure 1 , step S400 in the present application includes: merging the dot-extracted inkjet images to obtain a new merged inkjet image 50, and loading the merged inkjet image 50 to the inkjet process for inkjet processing. Figure 4

[0060] As can be seen from the above, the image inkjet method provided by the present application can analyze and mark different types of patterns selected for inkjet by parsing the selected image, set the required dot extraction ratio for different types of patterns according to the preset inkjet thickness, and dot extraction, and synthesize a new merged inkjet image 50 according to the dot-extracted inkjet image, and inkjet the merged inkjet image 50, so as to obtain the required inkjet thickness of the selected different types of patterns, improve the problems of stripes, exposure, edge blur and other problems after inkjet, and improve the inkjet quality of the image.

[0061] The specific steps of the image inkjet method in one specific embodiment will be described below, as shown in Figure 1 , the specific steps include:

[0062] Step S100 includes: parsing the current inkjet image, and selecting different types of patterns according to the parsing result, and the unselected patterns are the remaining patterns.

[0063] Step S200 includes: marking and distinguishing different types of patterns and remaining patterns to form a plurality of inkjet images.

[0064] Step S300 includes: setting a plurality of dot extraction ratios for a plurality of inkjet images according to a preset inkjet thickness, and performing dot extraction processing.

[0065] ​Step S400 includes merging each of the dot-picking processed printing images to obtain a merged printing image 50, as shown in FIG. 5, and loading the merged printing image 50 to a printing process for printing processing. Figure 4 Step S400 includes merging each of the dot-picking processed printing images to obtain a merged printing image 50, as shown in FIG. 5, and loading the merged printing image 50 to a printing process for printing processing.

[0066] The specific steps of the image printing method in another specific embodiment are described below, as shown in FIG. 4, and include the following specific steps: Figure 2

[0067] Step S110: Analyzing the printing thickness of the current printing image, selecting different types of patterns according to different thickness requirements, and the unselected patterns are the remaining patterns with the same thickness.

[0068] Step S200 includes marking and distinguishing different types of patterns and remaining patterns to form a plurality of printing images.

[0069] Step S300 includes setting a plurality of dot-picking ratios for a plurality of printing images according to a preset printing thickness, and performing dot-picking processing.

[0070] Step S400 includes merging each of the dot-picking processed printing images to obtain a merged printing image 50, as shown in FIG. 5, and loading the merged printing image 50 to a printing process for printing processing. Figure 4 Step S400 includes merging each of the dot-picking processed printing images to obtain a merged printing image 50, as shown in FIG. 5, and loading the merged printing image 50 to a printing process for printing processing.

[0071] The specific steps of the image printing method in another specific embodiment are described below, as shown in FIG. 4, and include the following specific steps: Figure 3

[0072] Step S100: Analyzing the current printing image and selecting different types of patterns according to the analysis result, and the unselected patterns are the remaining patterns.

[0073] Step S210: String marking is performed on different types of patterns and remaining patterns to form a plurality of printing images with string marking. Taking four patterns as an example, the first pattern is marked with mark_layer1, the second pattern is marked with mark_layer2, the third pattern is marked with mark_layer3, and the pattern without string marking is marked as a remaining pattern.

[0074] Step S220: Color marking is performed on different types of patterns and remaining patterns to form a plurality of printing images with color marking. Specifically, the first pattern corresponding to mark_layer1 is marked with red, the second pattern corresponding to mark_layer2 is marked with green, the third pattern corresponding to mark_layer3 is marked with blue, and the remaining pattern is marked with yellow.

[0075] ​​Step S230, rasterizing the marked different types of patterns and the remaining pattern into images of the same size. Specifically, the first, second, third and fourth inkjet images 51, 52, 53 and 54 marked by four thicknesses, four colors and four string marks are formed respectively. In this application, for the four inkjet images, the color palette can be specified when inkjet printing, and the gray value of 0 is defined as black, and the gray value of 255 is defined as white, that is, the black part in the figure is the non-printing part, and the white part in the figure is the part that needs to be printed when inkjet printing.

[0076] Step S310: preset a different dot extraction ratio for each inkjet image with different inkjet thicknesses, and perform dot extraction processing respectively. Specifically, the dot extraction ratio of the first inkjet image 51 in Figure 5 is 25%, the dot extraction ratio of the second inkjet image 52 in Figure 6 is 60%, the dot extraction ratio of the third inkjet image 53 in Figure 7 is 70%, and the dot extraction ratio of the fourth inkjet image 54 in Figure 8 is 50%.

[0077] Step S400 includes: merging each inkjet image after dot extraction processing, and retaining the thickness information, pattern string mark information and color mark information of each image during merging, and obtaining the merged inkjet image 50 shown in Figure 4 , and loading the merged inkjet image 50 to the inkjet printing process for inkjet printing processing. The merged inkjet image 50 after merging is still the non-printing part in the figure, and the part that needs to be printed when inkjet printing is the white part in the figure.

[0078] Therefore, in this application, different marks can be added to the patterns of different numbers of regions for identification and targeted dot extraction processing, so that local dot extraction can be performed on any number of regions, and various inkjet quality problems caused by consistent inkjet thickness and single dot extraction ratio when printing different patterns on a PCB can be solved.

[0079] It can be understood that, compared with the single dot extraction ratio of the to-be-printed image 60 shown in the related art Figure 9 , the four patterns contained in the merged inkjet image 50 of this application have been subjected to different dot extraction processing according to different thicknesses and marks, so that the selected different types of patterns can be subjected to different dot extraction processing in the inkjet printing process, and the quality of the PCB inkjet image obtained when inkjet printing is better, and the image quality problems such as stripes, bare bottom and blurred edges that may occur in the inkjet printing process are effectively improved.

[0080] The image inkjet device 100 of the present application is described below.

[0082] The analysis module 10 is used for analyzing the current jet printing image and selecting different types of patterns according to the analysis result, and the unselected patterns are the remaining patterns. The characteristics of the current jet printing image are described above and will not be repeated here. In this application, the computer-aided manufacturing software is used to analyze the pattern information of the current jet printing image in the original ODB++ data, and determine different types of patterns and the remaining patterns.

[0083] The marking module 20 is used for marking and distinguishing the selected different types of patterns and the remaining patterns to form a plurality of jet printing images. When marking, the computer-aided manufacturing software can be used to add attribute operation text definition, such as adding corresponding string. The computer-aided manufacturing software can also be used to add different color indexes, such as marking different colors; or different colors are marked for different types of patterns and the remaining patterns marked with strings.

That is, in this application, each of the plurality of jet printing images can be preset with a thickness information, and different dot extraction processing is performed according to the respective thickness information. For example, the jet printing thickness of the plurality of jet printing images and the dot extraction ratio have a one-to-one mapping relationship.

[0085] The image jet printing module 40 is used for merging the dot extraction processed jet printing images to obtain a merged jet printing image 50, and loading the merged jet printing image 50 to a jet printing process for jet printing processing.

[0086] As can be seen from the above, the image jet printing device 100 provided by the present application realizes the selected different types of patterns to obtain the required jet printing thickness by analyzing and marking the different types of patterns to be jet printed, setting the required dot extraction ratio for the different types of patterns according to the preset jet printing thickness and dot extraction, and jet printing the merged jet printing image 50 according to the new merged jet printing image 50 synthesized after dot extraction processing, thereby improving the problems of stripes, bare bottom and edge blur after jet printing, and improving the jet printing quality of the image.
