Description

Technical Field

[0001] The present invention relates to the technical field of printing production management, and particularly relates to a printing production management system. Background Art

[0002] Printing is a technology that transfers the original manuscript such as text, pictures, photos, anti-counterfeiting, etc. to the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, ink application, and pressure application, and batch reproduces the content of the original manuscript. Printing is the process of transferring the approved printing plate to the printing substrate through a printing machine and special ink.

[0003] According to the different colors to be printed, common printing production is divided into two types: single-color printing and color printing. Single-color printing is not limited to black only, and any one color display is single-color printing. Color printing is also called multicolor printing, which is further divided into three categories: additive method, color separation method, and composite color method. Among the common color printed products in the market, except for a very small number using the additive method and the color separation method, all are printed by the composite color method. The composite color method is further divided into two types: additive color method and subtractive color method. The common one is the four-color printing in the subtractive color method. By transferring the four-color inks of CMYK (i.e., cyan, magenta, yellow, and black) to the printing substrate for color formation, various colors of the original manuscript can be reproduced through different proportions of these four colors.

[0004] Therefore, when producing color printed materials, multiple printing devices are required. Different devices are used for different primary colors, that is, the four colors of CMYK. The primary color plates are reprinted on the same printed material, and different color printed materials are obtained due to different overlapping areas of the primary colors. Therefore, when a certain primary color printing sub-device fails, the final product obtained will not meet the design requirements. In the conventional processing methods, most of them are to repair the entire device and check each primary color printing sub-device separately, and it is impossible to quickly identify the fault location, which seriously affects the production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a printing production management system to solve the following technical problems:

[0006] In the conventional processing methods, most of them are to repair the entire device and check each primary color printing sub-device separately, and it is impossible to quickly identify the fault location, which seriously affects the production efficiency.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0012] A data processing module, which is used to extract the detection image and the finished product image, divide the detection image and the finished product image into several sub-images according to a preset specification and number them, and the sub-images of the detection image and the finished product image are defined as detection sub-images and finished product sub-images in sequence;

[0013] A fault detection module, which compares the finished product image with the target image, acquires the finished product sub-images corresponding to the parts in the finished product image that are different from the target image, and compares the finished product sub-images with the detection sub-images with the same number, identifies the detection image corresponding to the detection sub-image with the highest similarity to the finished product sub-image, and analyzes to obtain fault information.

[0014] As a further solution of the present invention: after the finished product image is extracted in real time, image preprocessing is performed on the finished product image, and the image preprocessing includes image noise reduction and size adjustment, and the size adjustment is to adjust the size of the finished product image to be the same as the size specification of the detection image.

[0015] As a further solution of the present invention: in the process of comparing the detection image with the target image, if the two are the same, it is determined that the equipment is operating normally.

[0016] As a further solution of the present invention: the acquisition process of the detection image includes the following steps:

[0017] Acquire the arrangement order of different primary color printing sub-devices;

[0018] Acquire the image data generated after the printing substrate passes through different primary color printing sub-devices in sequence according to the arrangement order of the primary color printing sub-devices;

[0019] Define the image data as a detection image, and establish a corresponding relationship between the detection image and the printing sub-devices that did not participate in its generation.

[0020] As a further solution of the present invention: the primary color printing sub-device module includes a cyan printing sub-device, a magenta printing sub-device, a yellow printing sub-device, and a black printing sub-device.

[0021] As a further solution of the present invention: The analysis steps of the fault information are specifically as follows:

[0022] Obtain the finished product image and the target image;

[0023] Identify the parts where the finished product image is different from the target image;

[0031] Set the grid size, establish a grid on the image based on the rectangular coordinate system, and divide the image into several sub-images;

[0032] Number the sub-images, and the number content selects the coordinates of the center point of the sub-image.

[0033] As a further solution of the present invention: During the process of dividing the detection image and the finished product image into sub-images, the detection image or the finished product image is evenly divided into 9 identical sub-images in the format of 3×3 and numbered in sequence.

[0034] Advantages of the present invention: In response to the situation in the common four-color printing production process in the market, when different primary-color printing sub-devices malfunction, the obtained products cannot meet the design requirements. The conventional method of checking one by one is rather complicated and seriously affects production efficiency. Therefore, in the present invention, the situations of malfunctions of different primary-color printing sub-devices are summarized, and the images of the products produced after one or several primary-color printing sub-devices malfunction and stop operating are detected and recognized. Thus, according to the finished product images collected in real time during actual production, and through subsequent division and recognition comparison, information about the faulty device can be obtained based on the detected images, thereby playing a role in rapid identification. Brief Description of the Drawings

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] Figure 1 It is a schematic structural diagram of a printing production management system provided in a preferred embodiment of the present invention. Detailed Embodiments

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1 As shown, the present invention is a printing production management system, including:

[0039] A printing equipment module, including primary-color printing sub-devices. The printing material passes through different primary-color printing sub-devices in sequence to produce a color print.

[0040] An image decomposition module, which acquires an image of the target color print and defines it as the target image, and acquires the image data of the printing material after passing through different primary-color printing sub-devices in sequence. The image data is defined as the detected image.

[0041] A data extraction module, which is used to acquire the image data of the finished color print in real time and defines it as the finished product image.

[0042] A data processing module, which is used to extract the detected image and the finished product image, divide the detected image and the finished product image into several sub-images according to a preset specification and number them. The sub-images of the detected image and the finished product image are defined as the detected sub-images and the finished product sub-images in sequence.

[0043] The fault detection module compares the finished product image and the target image, obtains the finished product sub-image corresponding to the part of the finished product image that is different from the target image, and compares the finished product sub-image with the detection sub-image with the same number, identifies the detection image corresponding to the detection sub-image with the highest similarity to the finished product sub-image, and analyzes to obtain the fault information.

[0044] First, the application scenario of the present invention is applied to CMYK four-color subtractive printing. The primary color plates are reprinted on the same printing material, and different color prints are obtained due to different overlapping areas of the primary colors. The above-mentioned equipment for the primary color plates refers to the primary color printing sub-equipment in the present invention. Different primary color printing sub-equipments reprint different primary color plates on the printing material to obtain color prints. According to the normal production process, the blank printing material passes through different primary color printing sub-equipments in sequence to produce the target product. It can be understood that during the formal production process, the various primary color printing sub-equipments corresponding to CMYK four colors are reprinted on the printing material in a fixed order. Therefore, when a certain primary color printing sub-equipment is damaged or not working, its printed product will be completely different from the target product. By comparing the printed product in actual production with the collected detection image, it is possible to analyze which primary color printing sub-equipment has a fault.

[0045] In another case of this embodiment, during the process of comparing the detection image and the target image, if they are the same, it is determined that the equipment is operating normally. This refers to the fact that the product of actual production is exactly the same as the target product, and all equipment is operating normally.

[0046] In a preferred embodiment of the present invention, after the finished product image is extracted in real time, image preprocessing is performed on the finished product image. The image preprocessing includes image noise reduction and size adjustment. The size adjustment is to adjust the size of the finished product image to be the same as the size specification of the detection image.

[0047] In another preferred embodiment of the present invention, the process of obtaining the detection image includes the following steps:

[0048] Obtain the arrangement order of different primary color printing sub-equipments;

[0049] Obtain the image data generated after the printing material passes through different primary color printing sub-equipments in sequence according to the arrangement order of the primary color printing sub-equipments;

[0050] Define the image data as the detection image, and establish a corresponding relationship between the detection image and the printing sub-equipment that did not participate in its generation.

[0051] Here, it is worth noting that one of the methods for obtaining the detection image is as shown above. The arrangement order of the different primary color printing sub-devices refers to the arrangement mode of the primary color printing sub-devices in actual production mentioned above. In the process of obtaining the detection image, passing through different primary color printing sub-devices in sequence means the image after passing through the first primary color printing sub-device, the image after passing through the first and second primary color printing sub-devices, the image passing through the first to the third primary color printing sub-devices in sequence, and the image passing through the first to the fourth primary color printing sub-devices in sequence. The above four images are images under normal working conditions. Therefore, the detection image also includes the image after passing through the first and third primary color printing sub-devices, the image passing through the first, second, and fourth primary color printing sub-devices in sequence, the image passing through the first, third, and fourth primary color printing sub-devices in sequence, and the image passing through the first and fourth primary color printing sub-devices in sequence. These are the finished product images after defaulting that two devices have failed and are out of service. And the above corresponding relationship can be understood as follows: in the image passing through the first to the third primary color printing sub-devices in sequence, the corresponding printing sub-devices are the second and fourth printing sub-devices. Similarly, the detection image also includes the image of the printing material passing only through the first primary color printing sub-device, the image of the printing material passing only through the second primary color printing sub-device, the image of the printing material passing only through the third primary color printing sub-device, and the image of the printing material passing only through the fourth primary color printing sub-device. These are the finished product images after defaulting that three devices have failed and are out of service. The primary color printing devices corresponding to the detection image are the three primary color printing sub-devices that have failed and are out of service.

[0052] It can be understood that the primary color printing sub-device module includes a cyan printing sub-device, a magenta printing sub-device, a yellow printing sub-device, and a black printing sub-device. The cyan printing sub-device, the magenta printing sub-device, the yellow printing sub-device, and the black printing sub-device correspond to the CMYK four colors in four-color printing in sequence.

[0053] In a preferred embodiment of the present invention, the specific steps for dividing the sub-images are as follows:

[0054] Extract image data, and the image data includes the detection image and the finished product image;

[0055] Establish a rectangular coordinate system with the key points of the image as the origin, and the key points include the center point and corner points of the image;

[0056] Set the grid size, establish a grid on the image based on the rectangular coordinate system, and divide the image into several sub-images;

[0057] Number the sub-images, and select the coordinates of the center point of the sub-images as the content of the numbering.

[0058] In a preferred embodiment of the present invention, the analysis steps of the fault information are specifically as follows:

[0059] Obtain the finished product image and the target image;

[0060] Identify the parts where the finished product image is different from the target image;

[0061] Obtain the finished product sub-images corresponding to the parts;

[0062] Obtain the detection sub-images corresponding to the finished product sub-images and compare the finished product sub-images with different detection sub-images in sequence;

[0063] Obtain the detection image corresponding to the detection sub-image with the highest similarity to the finished product sub-image;

[0064] Obtain the primary color printing sub-device corresponding to the detection image and determine that the primary color printing sub-device is faulty.

[0065] In this embodiment, the above-mentioned detection image and finished product image are divided into multiple sub-images according to a preset specification. It can be understood that for the situation where the device fails, in not all cases will the primary color printing sub-device stop completely. There are also cases where it does not stop, but during the reprinting process, it cannot meet the design requirements, resulting in some positions being unable to be reprinted, thus affecting the quality of the finished product. For this situation, due to the uncertainty of the above-mentioned parts that cannot be reprinted, the detection image is divided into several smaller sub-images to compare with the sub-images at the same positions of the finished product image, so as to know which sub-image of the detection image is the same as the unprinted part in the finished product image, and thus know the faulty primary color printing sub-device.

[0066] In another case of this embodiment, during the process of dividing the detection image and the finished product image into sub-images, the detection image or the finished product image is evenly divided into 9 identical sub-images in a 3×3 format and numbered in sequence. In addition to the above-mentioned grid division, there is also the equal division in this embodiment, that is, the image is equally divided into several parts and numbered in a clockwise, counterclockwise, or other order.

[0067] The above has described a detailed description of an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
