[0029] Example 1

[0030] Figure 1a The flowchart of a method for controlling the amount of ink at the edge of a printed image is provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the amount of ink at the edge of an image to be printed. The method can be executed by a device for controlling the amount of ink at the edge of the printed image, which can be implemented in hardware and / or software.

[0031] Correspondingly, such as Figure 1a As shown, the method includes:

[0032] S110. Obtain the image to be printed and the image description information corresponding to the image to be printed.

[0033] The image to be printed can be any image that needs to be printed.

[0034] In this embodiment, the edge areas of the image to be printed may be uneven, and the edge areas need to be processed to control the amount of ink at the edges of the image.

[0035] Additionally, image description information can be information that describes the image to be printed. This image description information includes a unique identifier to distinguish different images to be printed; each image corresponds to a unique identifier.

[0036] S120. The image description information is input into a pre-built image parameter database for matching to obtain image edge information parameters corresponding to the image to be printed.

[0037] The image parameter database can be a database that includes image description information and image edge information parameters. Specifically, image description information can be matched within the image parameter database to obtain the corresponding image edge information parameters.

[0038] Additionally, the image edge information parameters can be information describing the edges of the printed image. The image edge information parameters may include at least one of the following: at least one edge ink volume control distance, a starting grayscale value and an ending grayscale value corresponding to each edge ink volume control distance, and a pixel interval extraction value; in two adjacent edge ink volume control distances, the ending grayscale value of the preceding edge ink volume control distance and the starting grayscale value of the following edge ink volume control distance are the same.

[0039] Specifically, the edge ink volume control distance can be the distance for controlling the edge ink volume. The image to be printed includes at least one edge ink volume control distance, differentiated according to the different image parameters corresponding to the image to be printed. The starting grayscale value can be the initial grayscale value corresponding to the edge ink volume control distance, with a grayscale value range of 0-255. The ending grayscale value can be the ending grayscale value corresponding to the edge ink volume control distance. The pixel interval extraction value can be the value of the interval extracted from the outermost layer of pixels in the image to be printed.

[0040] For example, suppose the image edge information parameters matched to the image to be printed have two edge ink volume control distances: edge segment one ink volume control distance and edge segment two ink volume control distance. The edge segment one ink volume control distance corresponds to a starting grayscale value of 120 and an ending grayscale value of 80; the edge segment two ink volume control distance corresponds to a starting grayscale value of 80 and an ending grayscale value of 40. Furthermore, the edge segment one ink volume control distance is 2mm, and the edge segment two ink volume control distance is 1mm.

[0041] It is understandable that the ending grayscale value corresponding to the ink volume control distance of the first edge segment is the same as the starting grayscale value corresponding to the ink volume control distance of the second edge segment, both being 80.

[0042] S130. Based on the image edge information parameters, the image to be printed is divided into regions to obtain at least one image division region, and the pixels of the at least one edge region are extracted by means of a ratio value matched with the image edge information parameters to obtain a first processed image.

[0043] The image segmentation region includes a non-edge region and at least one edge region.

[0044] The image segmentation region can be a region obtained by dividing the image. The image segmentation region includes one non-edge region and at least one edge region.

[0045] Additionally, the ratio value can be the magnitude of the pixel extraction ratio for different edge regions. The ratio value differs in different edge regions, and also varies at different locations within the same edge region.

[0046] The first processed image can be an image obtained by pixel extraction of the edge region.

[0047] Optionally, the step of dividing the image to be printed into regions based on image edge information parameters to obtain at least one image division region includes: dividing the image to be printed into regions based on the ink volume control distance of each edge to obtain at least one image division region.

[0048] Continuing from the previous example, such as Figure 1b The diagram shows a schematic of the image region division structure. The ink volume control distance for the first edge segment is 1mm, and the ink volume control distance for the second edge segment is 2mm. Based on the ink volume control distance at the edges, the image to be printed can be divided into three image regions: one non-edge region and two edge regions, namely edge region 1 and edge region 2.

[0049] Optionally, the step of extracting pixels from at least one edge region using a proportional value matched with the image edge information parameters to obtain a first processed image includes: calculating at least two linear grayscale values ​​corresponding to each edge region based on the starting grayscale value and the ending grayscale value corresponding to each edge ink control distance, and the edge ink control distance; calculating the proportional value corresponding to each linear grayscale value, and extracting pixels from each edge region using the proportional value to obtain a first processed image.

[0050] Among them, the linear grayscale value can be the grayscale value corresponding to each position in the edge region.

[0051] Continuing with the previous example, the starting grayscale value for the first edge ink volume control distance is 120, and the ending grayscale value is 80; the starting grayscale value for the second edge ink volume control distance is 80, and the ending grayscale value is 40.

[0052] Since the ink volume control distance at the edge is 1mm, assuming the horizontal coordinate of position A is 0.5mm, the linear grayscale value corresponding to 0.5mm can be calculated as follows: The calculated linear grayscale value is 100.

[0053] Furthermore, a ratio value can be calculated, and pixels can be extracted from each of the edge regions using the ratio value to obtain the first processed image.

[0054] Optionally, the step of calculating the proportional value corresponding to each of the linear grayscale values ​​and extracting pixels from each of the edge regions using the proportional value to obtain the first processed image includes: according to the formula The ratio value P is calculated; where V represents the linear grayscale value; according to at least two ratio values ​​that match each edge region, pixels are extracted from each edge region to obtain the first processed image.

[0055] Continuing the previous example, assuming that the linear grayscale value at the position with an abscissa of 0.5mm in the edge region corresponding to the ink volume control distance of the edge segment is 100, then according to the formula... Calculate the ratio value. Then, based on the ratio value, extract pixels along the vertical axis with an abscissa of 0.5mm from the edge region corresponding to the ink volume control distance of the edge segment.

[0056] Similarly, it can be calculated that the linear grayscale value at the position with an abscissa of 0mm in the edge region corresponding to the ink volume control distance of the edge segment is 120, and the calculated ratio is 47.06%. Pixel extraction is performed on the vertical axis of the edge region with an abscissa of 0mm corresponding to the ink volume control distance of the edge segment.

[0057] Additionally, the linear grayscale value at the position with an abscissa of 1mm in the edge region corresponding to the ink volume control distance of the edge segment is 80, and the calculated ratio is 31.37%. Pixel extraction is performed on the vertical axis with an abscissa of 1mm in the edge region corresponding to the ink volume control distance of the edge segment.

[0058] Correspondingly, pixels are extracted from other edge regions to obtain the first processed image.

[0059] The advantage of this setting is that by calculating the ratio based on the starting grayscale value and ending grayscale value corresponding to each edge ink volume control distance, as well as the edge ink volume control distance, and extracting pixels from different edge regions, a corresponding first processed image is obtained. The first processed image obtained in this way is more accurate, thereby enabling control of the edge ink volume.

[0060] S140. Based on the image edge information parameters, perform pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed to obtain the second processed image.

[0061] The second processed image can be an image obtained by extracting the pixel interval of the outermost layer of pixels corresponding to the image to be printed.

[0062] Optionally, the step of performing pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed according to the image edge information parameters to obtain a second processed image includes: acquiring and performing pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed according to the pixel interval extraction value to obtain a second processed image.

[0063] The pixel interval extraction value can be the preset extraction value of the outermost pixel.

[0064] In this embodiment, the pixel interval sampling value can be set to any natural number. Assuming the pixel interval sampling value is 3, the outermost layer of pixels corresponding to the image to be printed is sampled according to the pixel interval sampling value of 3 to obtain the second processed image.

[0065] S150. Based on the first processed image and the second processed image, determine the edge ink volume control printing image corresponding to the image to be printed.

[0066] Among them, the edge ink volume control inkjet image can be the inkjet image after the edge ink volume of the image to be printed is controlled.

[0067] Optionally, determining the edge ink volume control printing image corresponding to the image to be printed based on the first processed image and the second processed image includes: acquiring the first processed image and the second processed image; combining the image of the non-outermost layer pixels corresponding to the first processed image and the image of the outermost layer pixels corresponding to the second processed image to determine the edge ink volume control printing image corresponding to the image to be printed.

[0068] In this embodiment, the image of the non-outermost layer of the first processed image and the image of the outermost layer pixels corresponding to the second processed image are selected, and the two images are combined to obtain the edge ink volume control inkjet image.

[0069] The advantage of this setting is that by extracting the pixel interval value, the outermost layer of pixels corresponding to the image to be printed is processed to obtain the second processed image. The outermost layer of pixels corresponding to the second processed image is more in line with the requirements of edge ink volume control. Since the extraction of edge areas may not be able to better control the edge ink volume of the image, the second processed image can better process the outermost layer of pixels of the image to be printed.

[0070] The technical solution of this invention involves acquiring an image to be printed and corresponding image description information; inputting the image description information into a pre-constructed image parameter database for matching to obtain image edge information parameters corresponding to the image to be printed; dividing the image to be printed into regions based on the image edge information parameters to obtain at least one image region, and extracting pixels from each of the at least one edge region using a ratio value matched with the image edge information parameters to obtain a first processed image; performing pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed based on the image edge information parameters to obtain a second processed image; and determining an edge ink volume control printing image corresponding to the image to be printed based on the first processed image and the second processed image. This solves the problems of uneven edges and small peaks in the printed image, achieves precise control of ink volume at the edges of the printed image, further improves the flatness of the edge region of the printed image, and enhances the printing quality.

[0071] Example 2

[0072] Figure 2 This is a flowchart of another method for controlling the amount of ink at the edge of a printed image, provided in Embodiment 2 of the present invention. This embodiment is an optimization based on the above embodiments. In this embodiment, before obtaining the image to be printed and the image description information corresponding to the image to be printed, a specific operation process for constructing an image parameter database is also included.

[0073] Correspondingly, such as Figure 2 As shown, the method includes:

[0074] S210. Obtain each historical inkjet image and the historical image description information corresponding to each historical inkjet image.

[0075] Historical print images can be images that were previously intended to be printed. Historical image description information can be information describing the historical print images.

[0076] S220. Each of the historical inkjet images is analyzed and processed to obtain the historical image edge information parameters corresponding to each historical inkjet image.

[0077] Among them, the historical image edge information parameter can be information describing the edges of historical inkjet images.

[0078] S230. The historical image description information and historical image edge information parameters corresponding to each historical inkjet image are jointly matched and stored to construct an image parameter database.

[0079] In this embodiment, historical inkjet images are acquired and parsed to obtain corresponding historical image description information and historical image edge information parameters. The historical image description information and historical image edge information parameters are jointly stored to determine the image parameter database.

[0080] S240: Obtain the image to be printed and the image description information corresponding to the image to be printed.

[0081] S250. The image description information is input into a pre-built image parameter database for matching to obtain image edge information parameters corresponding to the image to be printed.

[0082] In this embodiment, the method further includes inputting image description information into a pre-built image parameter database for matching. If no image edge information parameters corresponding to the image to be printed are obtained, the image to be printed is fed back. When the operator receives the image to be printed, they manually determine the image edge information parameters and control the amount of ink at the edges of the image to be printed based on the determined image edge information parameters. This improves the flexibility of controlling the amount of ink at the edges of the image to be printed.

[0083] S260. Based on the image edge information parameters, the image to be printed is divided into regions to obtain at least one image division region, and pixels are extracted from the at least one edge region by means of a ratio value matched with the image edge information parameters to obtain a first processed image.

[0084] S270. Based on the image edge information parameters, perform pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed to obtain the second processed image.

[0085] S280. Based on the first processed image and the second processed image, determine the edge ink volume control printing image corresponding to the image to be printed.

[0086] The technical solution of this invention involves: acquiring historical inkjet images and corresponding historical image description information; parsing each historical inkjet image to obtain historical image edge information parameters; jointly matching and storing the historical image description information and historical image edge information parameters corresponding to each historical inkjet image to construct an image parameter database; acquiring an image to be printed and corresponding image description information; inputting the image description information into the pre-constructed image parameter database for matching to obtain image edge information parameters corresponding to the image to be printed; dividing the image to be printed into regions based on the image edge information parameters to obtain at least one image region, and extracting pixels from each of the at least one edge region using a ratio value matched with the image edge information parameters to obtain a first processed image; performing pixel interval extraction processing on the outermost layer pixels corresponding to the image to be printed based on the image edge information parameters to obtain a second processed image; and determining an edge ink volume control inkjet image corresponding to the image to be printed based on the first processed image and the second processed image. A more comprehensive image parameter database was constructed, which improved the flexibility of edge ink volume control of the image to be printed, realized precise control of the ink volume at the edge of the printed image, further improved the flatness of the edge area of ​​the printed image, and enhanced the printing quality.
