[0002] With the widespread application of computers in graphics and text processing, printers have become increasingly common, allowing people to easily output text or graphics from their computers to print media. However, with technological advancements, people desire text or graphics that not only output to print media but also meet various requirements for detail and color accuracy. To meet these requirements, current technology first performs color management on the image to meet color accuracy requirements, and then uses a 2-bit dot matrix algorithm for dot processing to meet detail accuracy requirements.

Where there is no conflict, embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the scope of protection of the present invention.

[0048] Example 1

[0049] like Figure 1 As shown, this embodiment provides a method for processing regional printing data, the method including the following steps:

[0050] S1: Obtain printing accuracy requirements and / or printing color requirements. Divide the image to be printed into at least a first printing area and a second printing area, wherein the printing accuracy requirements and / or printing color requirements of the first printing area are higher than those of the second printing area.

[0051] In this step, the parts of the image to be printed that require high color and detail can be selected. Figure 2 Regions F and B1 in the middle, Figure 3 Regions F and B2 in the middle, Figure 4 The F and B3 areas in the image are designated as the first printing area, while the areas with lower color and detail are designated as the second printing area. Figure 2 Regions A1 and C1 in the text Figure 3 Regions A2 and C2 in the text Figure 4 The A3 and C3 areas in the image are designated as the second printing area. For example, when the image to be printed is a product icon, the background area with higher requirements for color saturation and detail is designated as the first printing area, while the parts containing images with lower requirements for color saturation and detail, such as barcodes, QR codes, serial numbers, and timestamps, are designated as the second printing area.

[0052] Wherein the printing precision requirement and / or printing color requirement of the first printing area is higher than the printing precision requirement and / or printing color requirement of the second printing area, it means that the printing precision requirement of the first printing area is higher than the printing precision requirement of the second printing area, or the printing color requirement of the first printing area is higher than the printing color requirement of the second printing area, or the printing precision requirement of the first printing area is higher than the printing precision requirement of the second printing area at the same time.

[0053] Dividing the image to be printed into at least a first printing area and a second printing area based on printing accuracy and / or printing color requirements means that the number of areas into which the image is divided according to printing accuracy and / or printing color requirements is greater than or equal to 2. That is, in addition to the aforementioned method of dividing into a first printing area and a second printing area, the image to be printed can also be divided into n printing areas based on printing accuracy and / or printing color requirements, where n is a positive integer greater than or equal to 2. At least two of the n divided printing areas must have different printing accuracy and / or printing color requirements.

[0054] S2: Receive the first print data obtained by the first processing end, wherein the first print data is print data of the first print area obtained by color management processing and / or dot matrix algorithm processing and represented by the first data length;

[0055] This step sends areas with high printing precision and / or color requirements to a first processing unit with stronger processing capabilities for color management and / or dot matrix algorithm processing. The processed data is then represented by a first data length. This embodiment significantly reduces the amount of data processed by the client by delegating the processing of areas with high printing requirements to the first processing unit, thus significantly improving the efficiency of printing data processing. The data length refers to the amount of storage space required to store the data, such as 1-bit, 2-bit, 4-bit, or 8-bit data. For example, when the first data length is 2 bits, the first printing data is represented by 2 bits. The first processing unit sends the processed first printing data to the printing device for subsequent processing. The dot matrix algorithm can use a halftone algorithm.

[0056] In this embodiment, step S2: receiving the first print data processed by the first processing terminal, wherein the first print data is print data of the first print area processed by color management and / or dot matrix algorithm and represented by a first data length, further includes the following steps:

[0057] like Figure 5 As shown, S21: Divide the first printing area into a first variable area and a first immutable area according to whether the local image in the first printing area changes;

[0058] When printing images such as product icons, a batch of print jobs often requires printing multiple copies of the product icon.

[0059] like Figures 2 to 4 As shown, these product icons often consist of image parts that remain unchanged and images that change. For example... Figures 2 to 4 The F area in the diagram represents the background portion of the product icon, which is the image portion that will not change. Figure 2 Region B1 in the middle, Figure 3 Middle B2 area, Figure 4 The B3 area in the image, along with areas A1, A2, and A3 representing the product icon's time, and areas C1, C2, and C3 representing the product icon's barcode, are all images that will change. The patterns that do not change are the same in every product icon, while the changing patterns can be different in each image.

[0060] S21: Divide the first printed area into a first movable area and a first immutable area based on whether the local image in the first printed area changes;

[0061] This step identifies the first printing area based on whether a local image within the first printing area changes, dividing the first printing area into two regions: a variable region and a non-variable region. Correspondingly, the data to be printed is also divided into two parts: a first non-variable print count and a second non-variable print data. The first non-variable print data corresponds to the unchanging portion of the image in the first printing area, while the second non-variable print data corresponds to the changing portion of the image in the first printing area.

[0062] S22: Receive the first immutable print data obtained by the first processing end from processing the first immutable area and store it in the storage device of the printing equipment;

[0063] This step sends the portion of the image to be printed that belongs to the first immutable area to a first processing terminal with strong processing capabilities for processing. After processing, the printing device receives the processed first immutable printing data and saves the first immutable printing data locally for later use.

[0064] S23: Before each printing, receive the first variable printing data obtained by the first processing end processing the first variable area according to the change content and position information of the first variable area, and obtain the first immutable printing data stored in the storage device.

[0065] In this embodiment, the printing device prints one image at a time. Since the variable portion of each image is different, before printing the current image, the printing device must receive the first variable print data corresponding to the first variable area from the first processing end. Before this, the first processing end performs data processing on the variable area of ​​the image to be printed based on the change content and position information of the first variable area, such as color management processing and dot matrix algorithm processing. Since the first immutable print data in the first print data is the same when printing each image, the first immutable print data is directly read from the local storage device, without needing to be processed by the first processing end and sent to the printing device each time. That is, the first processing end only processes the first variable area once, and the processed data only needs to be sent once. This greatly improves the efficiency of data processing and saves system resources.

[0066] S3: Perform dot matrix algorithm processing on the second printing area to obtain the second printing data, which is the printing data represented by the second data length.

[0067] This step allows areas with lower printing accuracy and / or color requirements to be processed by a processing device with lower processing capabilities, such as a client or a printing device, resulting in second print data represented by a second data length.

[0068] This embodiment partitions the image to be printed according to printing accuracy and / or printing color requirements. Areas with high printing accuracy and / or printing color requirements are processed using a more precise method, and the processing results are represented by a more precise bit data type, thus ensuring that the printing effect meets high printing requirements. Simultaneously, this embodiment uses a more efficient method to process areas with low printing accuracy and / or printing color requirements, and the processing results are represented by a smaller bit data type, thus improving data processing and transmission efficiency while meeting printing requirements. This embodiment significantly improves printing efficiency while ensuring the overall printing effect meets printing requirements through partitioning.

[0069] As a preferred embodiment, the first data length is 2 bits, and the second data length is 1 bit. This embodiment uses a 2-bit dot matrix algorithm to process the first printing area to obtain first printed data represented by 2 bits. A 1-bit dot matrix algorithm is used to process the second printing area to obtain first printed data represented by 1 bit. That is, in this embodiment, the unit data size of the first data is greater than the unit data size of the second data length. This embodiment uses 2-bit dot matrix processing to obtain 2-bit first printed data for the first printing area, which has high requirements for color and detail, and can accurately represent the color and detail of the printed image. For the second printing area, which has lower requirements for color and detail, the faster 1-bit dot matrix algorithm is used to obtain 1-bit first printed data, which can significantly improve data processing efficiency, speed up data transmission, and reduce storage requirements.

[0070] like Figure 6 In this embodiment, after step S3: performing dot matrix algorithm processing on the second printing area to obtain the second printing data, and the second printing data being printing data represented by the second data length, the following steps are also included;

[0071] S4: Obtain the number of various types of ink dots at the boundary between the first and second printing areas;

[0072] The ink dots at the boundary between the first and second printing areas refer to ink dots belonging to the first printing area but located near the boundary of the second printing area. For example, the ink dots in the first printing area that are closest to the boundary of the second printing area are the 1st, 2nd, or Kth rows of ink dots, where K is an integer greater than 2. The value of K can be set based on experience or printing requirements.

[0073] In this embodiment, the ink droplet type is classified according to the volume of the ink droplets forming the droplets. That is, ink droplets formed by ink droplets of the same volume belong to one type, and ink droplets formed by ink droplets of different volumes belong to different types. By controlling the drive waveform of the printhead, the printhead of the printing device can eject multiple ink droplets of different volumes. For example, some printing devices can eject a first type of ink droplet (the type of ink droplet that forms large ink droplets), a second type of ink droplet (the type of ink droplet that forms medium ink droplets), and a third type of ink droplet (the type of ink droplet that forms small ink droplets). The volume of the first type of ink droplet is larger than the volume of the second type of ink droplet, and the volume of the second type of ink droplet is larger than the volume of the third type of ink droplet. In this embodiment, the number of ink droplet types k can be a positive integer greater than or equal to 2, that is, the printhead can eject at least two types of ink droplets of different volumes. For example, when the first printed data is represented by 2 bits, the first printed data has four values: 0, 1, 2, and 3. Each value can correspond to a type of ink droplet. For example, value 0 corresponds to an empty dot, value 1 corresponds to a small dot, value 2 corresponds to a medium dot, and value 3 corresponds to a large dot. The volume of the ink droplet that forms a large dot is greater than the volume of the ink droplet that forms a medium dot, which is greater than the volume of the ink droplet that forms a small dot.

[0074] S5: Adjust the ink dot volume type of the second print data according to the number of ink dots of each type to obtain the third print data.

[0075] Because the second printing area uses a different bit data type than the first printing area, unnatural ink droplet transitions can easily occur at the boundary between the two areas. To address this, this step adjusts the second printing data corresponding to the second printing area based on the number of ink drops of different sizes at the boundary obtained in the previous step, and then prints using the adjusted third printing data. This allows the ink drops in the second printing area to transition naturally with those in the first printing area, thereby further improving the printing quality.

[0076] like Figure 7 As shown, in this embodiment, as a way to adjust the ink dot volume type of the second print data, step S5: adjusting the ink dot volume type of the second print data according to the number of ink dots of various types to obtain the third print data includes the following steps:

[0077] S51: Obtain the first threshold F;

[0078] The range of the first threshold F can be 40% to 60%, and as a preferred approach, the first threshold F is 50% to 52%.

[0079] S52: Calculate the percentage of each type of ink spot based on the number of each type of ink spot;

[0080] For example, there are three types of ink dots at the boundary between the first and second printing areas: large ink dots, medium ink dots, and small ink dots. The number of large ink dots is N1, the number of medium ink dots is N2, and the number of small ink dots is N3. Then, in this step, the proportion of large ink dots is k1 = N1 / (N1+N2+N3), the proportion of medium ink dots is k2 = N2 / (N1+N2+N3), and the proportion of small ink dots is k3 = N3 / (N1+N2+N3).

[0081] S53: Compare the proportion of each type of ink spot with the size of the first threshold;

[0082] S54: Adjust the ink dot volume type of the second print data based on the comparison result of the proportion of each type of ink dot with the size of the first threshold.

[0083] like Figure 8 As shown, the specific adjustment method includes the following steps:

[0084] S551: Obtain the volume type of ink dots whose quantity ratio is greater than the first threshold as the target volume type;

[0085] S542: After adjusting the ink dot volume type of the second print data to the target volume type, the third print data is obtained.

[0086] For example, if F = 50%, and the proportion of large ink dots is k1 = 60%, the proportion of medium ink dots is k2 = 30%, and the proportion of small ink dots is k3 = 10%, then the proportion of large ink dots is k1 greater than the first threshold F. In this case, the ink dot volume type of the second print data is adjusted to large ink dots to obtain the third print data.

[0087] For example, if F = 50%, and the proportion of large ink dots is k1 = 40%, the proportion of medium ink dots is k2 = 53%, and the proportion of small ink dots is k3 = 17%, then the proportion of medium ink dots is k2, which is greater than the first threshold F. In this case, the ink dot volume type of the second print data is adjusted to medium ink dots to obtain the third print data.

[0088] For example, if F = 50%, and the proportion of large ink dots is k1 = 25%, the proportion of medium ink dots is k2 = 21%, and the proportion of small ink dots is k3 = 54%, then the proportion of small ink dots is k3, which is greater than the first threshold F. In this case, the ink dot volume type of the second print data is adjusted to small ink dots to obtain the third print data.

[0089] In this embodiment, as another way to adjust the ink dot volume type of the second print data, step S5: adjusting the ink dot volume type of the second print data according to the number of ink dots of various types to obtain the third print data includes the following steps:

[0090] S55: Calculate the percentage of each type of ink dot based on the number of each type of ink dot;

[0091] S56: Obtain the volume type of the ink dot with the highest number of dots among various types as the target volume type.

[0092] For example, the proportion of large ink dots is k1 = 31%, the proportion of medium ink dots is k2 = 33%, and the proportion of small ink dots is k3 = 36%. Since the proportion of small ink dots is the highest, the volume type corresponding to small ink droplets is taken as the target volume type.

[0093] S57: After adjusting the droplet volume type of the second print data to the target volume type, the third print data is obtained.

[0094] For example, if the aforementioned steps take the volume type corresponding to the small ink droplets as the target volume type, then this step will adjust the ink droplet volume type of the second print data to small ink droplets to obtain the third print data.

The regional printing data processing device or the regional printing data processing equipment can establish a communication connection with the first processing end through wireless communication, wired communication, or a combination of wireless and wireless communication.

[0116] In this embodiment, the first printing area in the image to be printed is input to the first processing end for color management, and then processed by a dot matrix algorithm to obtain the first printing data represented by the first data length. The first immutable area in the first printing area is processed only once and will not be processed repeatedly. If this part of the image needs to be replaced, it needs to be processed again. Then, the first processing end directly sends the processed first immutable printing data to be stored in the inkjet printer. The first variable area in the first printing area is only processed by inputting the content of each change and the position parameters of the first variable area to the first processing end for color management, and then processed by a dot matrix algorithm to obtain the first immutable printing data represented by the first data length. At the same time, the second printing area generation rules are input into the label generator of the client. The label generator automatically generates and processes the second printing data according to the generation rules and the dot matrix algorithm.
