[0029] Embodiment One

[0030] Figure 1 A flow chart of a printing processing method provided by Embodiment One of the present application, the embodiment can be applied to print a mesh image on a suitable area of a circuit board, so as to avoid the case of large-area diffusion of black ink when formal printing is performed. The method can be executed by a printing processing device, which can be realized in the form of hardware and / or software, and can be configured in a computer or processor with image processing function. As shown in the figure, the method comprises the following steps. Figure 1

[0031] S110, obtaining a printing area pattern matched with a target printing image, and generating a mesh image according to a pre-selected target filling shape and the printing area pattern.

[0032] Optionally, the target printing image can be understood as an image that needs to be printed on the circuit board at present. It can be understood that, due to the chip and other structures on the circuit board, the image area corresponding to the position of the chip in the target printing image is a non-printing area, and the area outside the chip is a printing area.

[0033] Figure 2 As shown in the figure, a schematic diagram of an optional printing image is shown, wherein the shaded part can represent a printing area. Figure 2

[0034] It can be understood that the printing area pattern can refer to the pattern constituting the printing area in the target printing image, and can also be understood as the outline pattern of the printing area.

[0035] Optionally, the filling shape can include at least a circle, a rectangle and a regular polygon; different filling shapes have different filling arrangement modes when performing shape filling.

[0036] Optionally, the target filling shape can refer to the filling shape used to fill the printing area pattern, and the filling shape can also include a rhombus. The regular polygon can be a regular triangle, a square, a regular hexagon, etc., and the specific type of filling shape is not limited.

[0037] Figure 3 As shown in the figure, a schematic diagram of an optional filling shape arrangement mode is shown, wherein the arrangement modes of a circle, a square, a rectangle, a hexagon, a rhombus and a triangle are shown. Figure 3

[0038] Optionally, after the target filling shape and the printing area pattern are determined, the target filling shape can be appropriately arranged according to the arrangement mode of the target filling shape, so as to fill the printing area pattern, Figure 2 ​​​The shadow part can also be regarded as the filling result after filling the printing area pattern by the regular rhombus. It can be seen that the mesh structure is generated in the filled printing area pattern, that is, the printing area image is converted from the blank image to the mesh image.

[0039] S120, determining the black ink printing area in the printing area pattern according to the target printing image, and generating a mesh printing image according to the mesh image and the black ink printing area.

[0040] Optionally, in the process of printing the circuit board, only black ink and white ink are generally used for printing the circuit board, and the white ink printing area is generally small. The black ink can print the white block pattern and character pattern gathered in a large area. Since the white block area printing effect is a large area of black, the ink diffusion phenomenon is more obvious in the white block area.

[0041] In order to solve the above technical problems, the application creatively proposes that the black ink printing area in the target printing image is first printed with a mesh structure before printing the target printing image, and the pre-printed mesh structure can effectively avoid the large-area diffusion of black ink during subsequent printing.

[0042] Optionally, the black ink printing area and the white ink printing area can be obtained by performing image binarization processing on the target printing image, extracting the pixel values of each pixel point, and dividing the points with pixel values greater than the threshold value from the points with pixel values less than the threshold value according to the preset threshold value. For example, the threshold value can be set to 128, the pixel points that need to be printed with black ink have a pixel value of 0, and the pixel points that need to be printed with white ink have a pixel value of 255. Then, the image can be divided into points with a pixel value of 0 and points with a pixel value of 255. After the division, all pixel points with a pixel value less than the threshold value are identified, and the black ink printing area in the target printing image is determined. Then, the black ink printing area in the printing area pattern can be determined correspondingly.

[0043] Further, after determining the black ink printing area, the position corresponding to the black ink printing area in the mesh image can be determined, the mesh structure in the black ink printing area is retained, the mesh structure outside the black ink printing area is deleted, and the mesh printing image is generated.

[0044] S130, printing the target circuit board according to the mesh printing image and the target printing image.

[0045] Optionally, the mesh image is first printed on the circuit board, and then the target printing image is printed on the circuit board with the mesh image, at this time, the black ink at the position where the black ink is used more in the target printing image is limited in the mesh structure, which does not affect the content of the printed image and can solve the problem of black ink diffusion.

[0046] The technical scheme of the embodiment of the present application generates a region printing graph by analyzing the target printing image, fills the region printing graph by using the filling shape to generate a mesh image, extracts the black ink printing region in the printing region image, extracts the mesh printing image in the mesh image according to the black ink printing region, and then prints the mesh printing image on the circuit board, and in the manner of printing the target printing image on the circuit board, the size of the mesh structure can be controlled to control the diffusion range of the black ink, so that the problem of thick ink in some regions caused by black ink diffusion can be solved, and the problems of orange peel, color difference and uneven edges caused by ink diffusion can be solved, and the printing quality of the circuit board can be effectively improved.

As shown in the figure, the method comprises the following steps. Figure 4

[0049] S210, obtaining a target printing image and identifying edge size information of the target printing image.

[0050] Optionally, the edge size information can include the outer contour size of the printing image and the edge size of each non-printing region, and the size information can include the position coordinate information of each edge line in addition to the length of each edge.

[0051] S220, determining a printing region graph matched with the target printing image according to the edge size information of the target printing image.

[0052] Optionally, according to the edge size information, each edge of the printing region graph can be combined to determine the printing region graph.

[0053] Optionally, the printing region graph can also be obtained by other image processing methods, and the specific obtaining method of the printing region graph is not limited here.

[0056] It can be understood that after the target printing image is printed, the black ink is limited in the pre-printed mesh structure, and by setting the shape parameter of the target filling shape, the diffusion range of the black ink can be accurately controlled.

[0057] S240, filling the printing area pattern with the target filling shape according to the shape parameter of the target filling shape and the filling arrangement mode matched with the target filling shape, to generate a mesh image.

[0061] S280, determining a target area matched with each black ink printing area in the mesh image according to position information of each black ink printing area in the printing area pattern.

[0062] S290, retaining the target filling shape filled in each target area and deleting the target filling shape outside each target area, to generate a mesh printing image.

[0065] The technical scheme of the embodiment of the present application can generate a region printing pattern by analyzing a target printing image, fill the region printing pattern by using a filling shape to generate a mesh image, extract a black ink printing region in the printing region image, extract a mesh printing image in the mesh image according to the black ink printing region, and print the mesh printing image to a circuit board, so that the size of the mesh structure can be controlled to control the diffusion range of the black ink, avoid the thick ink in some regions caused by the diffusion of the black ink, and solve the problems of orange peel, color difference and uneven edges caused by the diffusion of the ink, thereby effectively improving the printing quality of the circuit board.
