Description

Technical Field

[0001] This invention belongs to the field of printing plate making technology, specifically relating to an intelligent printing and layout method and system for printed materials based on screen printing and die-cutting technology. Background Technology

[0002] In the printing industry, with the ever-growing market demand for personalized, high-precision printed materials, traditional printing technologies are struggling to meet diverse production requirements. Screen printing, a widely used method, offers advantages such as thick ink layers and strong three-dimensionality, but existing screen printing technologies have certain limitations. Some existing technologies achieve cutout effects, but they fall short in combining intelligent typesetting with high-precision screen printing, making it difficult to precisely control the integration of the cutout area with design elements, resulting in inconsistent print quality. Other screen printing technologies, while possessing basic printing functions, do not incorporate cutout techniques, failing to meet the market's demand for both cutout features and fine printing. Furthermore, some printed materials with cutout elements use pasted text, a method that is not only inefficient but also prone to problems such as text detachment and uneven edges, severely impacting the overall quality and aesthetics of the printed material. Simultaneously, traditional methods lack intelligent and precise means for controlling ink parameters, optimizing printing equipment parameters, and inspecting print quality during the printing process. Key factors such as ink viscosity and squeegee parameters are difficult to dynamically adjust according to actual conditions, leading to unstable printing results. Quality inspection relies heavily on manual labor, which is inefficient and prone to missed or false inspections. Therefore, it is urgent to develop an intelligent printing and layout method and system based on screen printing and die-cutting technology. This invention integrates multiple processes such as intelligent design, precise printing, dynamic parameter adjustment, and intelligent quality inspection, improving the quality and production efficiency of printed materials and meeting the market demand for high-quality, personalized printed products. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides an intelligent printing layout method and system based on screen printing and die-cutting technology. This method solves the problems of traditional screen printing, such as the difficulty in accurately integrating die-cutting and printing elements, the inability to dynamically optimize ink and equipment parameters, the low efficiency and error-prone nature of manual printing quality inspection, inaccurate control of irregular cutting and ink curing, and difficulties in sorting qualified and defective products. To achieve the above objectives, this invention adopts the following technical solution:

[0004] The intelligent printing and layout method for printed materials based on screen printing and die-cutting technology includes the following steps: An intelligent design system integrates user-inputted text and graphic elements; an image processing algorithm extracts the coordinate data of the die-cutting area; the design file is converted into a vector file suitable for screen printing to obtain a printing design draft; an electric screen tensioning machine controls the screen tension to the target value; an automated coating machine applies a photosensitive emulsion layer; the die-cutting coordinate data from the design draft is imported into an exposure machine for precise positioning and exposure to obtain a screen printing plate; a rheometer measures the ink viscosity and dynamically adjusts the solvent ratio; a pressure sensor optimizes the squeegee angle, pressure, and speed parameters; the adapted parameters are input into the printing equipment to obtain a combination of printing parameters; a camera scans the printed material across the entire surface; an image comparison algorithm extracts the location and type of defects; the quality inspection results are fed back to the control system to automatically adjust the printing parameters; defective areas are reprinted until they are qualified to obtain the printed material; a visual positioning system controls a cutting machine to complete irregular cutting; a hot air drying method is selected according to the ink type to ensure complete ink curing; qualified and defective products are sent to different channels to obtain finished printed materials.

[0005] Furthermore, the intelligent design system integrates user-inputted text and graphic elements, extracts coordinate data of the cutout areas using image processing algorithms, and converts the design file into a vector file suitable for screen printing to obtain the printing design draft. This includes the following steps: An interactive interface is constructed using the intelligent design system, allowing users to directly input text content and graphic elements. The system automatically vectorizes the input content and integrates it into a unified design layer; the outline of the cutout areas in the design is extracted using edge detection and morphological analysis algorithms, obtaining their coordinate positions, line widths, and spacing parameters; the non-cutout areas are filled and optimized; the extracted cutout data is logically superimposed on the basic design file, converting it into a vector format file that meets the requirements of the screen printing process, thus obtaining the printing design draft; the vector format file includes layered annotations for printing and non-printing areas.

[0006] Furthermore, the process of controlling the screen tension to the target value using an electric screen stretching machine, applying a photosensitive emulsion layer using an automated coating machine, and importing the cutout coordinate data from the design draft into an exposure machine for precise positioning and exposure to obtain the screen printing plate includes the following steps: using a tension sensor mounted on the electric screen stretching machine to monitor and dynamically adjust the tension of the screen frame in real time, precisely controlling the screen tension to the required 18-25 N / cm. 2 Target values; using a laser rangefinder equipped with an automated coating machine to ensure that the photosensitive adhesive layer is coated on the screen surface with a uniform thickness of 5-8μm, and to complete the curing degree detection of the adhesive layer; the coordinate data of the cutout area extracted by the intelligent design system is imported into the digital exposure machine using an encrypted transmission module; the screen and the film are bonded with zero gap through a vacuum adsorption device, and UV light source is used for precise irradiation to obtain a screen printing plate with transparent cutout areas and ink-resistant non-cutout areas.

[0007] Furthermore, the process of measuring ink viscosity and dynamically adjusting solvent ratio using a rheometer, optimizing squeegee angle, pressure, and speed parameters using a pressure sensor, and inputting the adapted parameters into the printing equipment to obtain a printing parameter combination includes the following steps: real-time viscosity detection of the ink using a rheometer, comparing the current viscosity value with a preset process range, and dynamically calculating the required solvent addition ratio; conveying the adjusted ink to a mixing device for homogenization, using a high-precision pressure sensor array to monitor the pressure distribution, angle offset, and movement speed at the squeegee-screen contact surface; extracting multi-dimensional parameters and optimizing them using an algorithm model to obtain the optimal printing pressure value, squeegee tilt angle, and operating speed; transmitting the optimized parameter combination to the printing equipment control module via an industrial bus to drive the mechanical unit to automatically calibrate, resulting in a standardized printing parameter combination.

[0008] Furthermore, the method of using a camera to scan the printed material across the entire frame, extracting the location and type of defects through image comparison algorithms, and feeding the quality inspection results back to the control system to automatically adjust printing parameters, reprinting the defective areas until they are qualified, and obtaining the printed material, includes the following steps: using a high-speed industrial camera to perform a full-frame, no-dead-angle scan of the printed material to obtain complete image data of the printed surface; using an image comparison algorithm to perform pixel-level comparison between the real-time scanned image and a standard template to extract the coordinate position, shape features, and defect type information of the defective area; feeding the quality inspection results back to the central control module of the printing equipment via an encrypted communication module, automatically calling a preset parameter adjustment strategy according to the defect type, and driving the squeegee pressure, ink supply, and printing speed to be corrected in real time; reprinting the corrected defective areas, repeating the process from image scanning, comparison and defect extraction, feedback and parameter adjustment to reprinting, until the quality inspection module determines that the image and template match the standard, and obtaining the printed material.

[0009] Furthermore, the process of controlling the cutting machine through a vision positioning system to complete irregular cutting, selecting a hot air drying method according to the ink type to ensure complete ink curing, and sending qualified and defective products to different channels to obtain finished printed products includes the following steps: real-time scanning of the printed product using a high-precision vision positioning system to extract its edge contour and feature point coordinate data, generating an irregular cutting path and transmitting it to the CNC cutting machine; automatically selecting a hot air circulation drying device for solvent-based inks based on ink composition analysis results, and ensuring complete ink curing through temperature and light intensity control; performing secondary quality inspection of the printed product using photoelectric sensors to extract surface flatness and color consistency indicators; and guiding qualified and defective products to different sorting channels to obtain finished printed products with precise edges and complete ink curing.

The system measures ink viscosity and dynamically adjusts solvent ratio. A pressure sensor optimizes squeegee angle, pressure, and speed parameters. These parameters are then input into the printing equipment to obtain a combination of printing parameters. The quality inspection module uses a full-frame camera to scan the printed material, extracts defect locations and types through image comparison algorithms, and feeds the inspection results back to the control system to automatically adjust printing parameters. Defective areas are reprinted until they are acceptable, resulting in a finished product. The finished product sorting module uses a vision positioning system to control a cutting machine for irregular cutting. Based on the ink type, a hot air drying method is selected to ensure complete ink curing. Qualified and defective products are then sorted into different channels to obtain the finished printed product.

[0011] A third aspect of the present invention provides an intelligent printing and typesetting device for printed materials based on screen printing and die-cutting technology. The intelligent printing and typesetting device for printed materials based on screen printing and die-cutting technology includes a memory and at least one processor. The memory stores instructions. The at least one processor invokes the instructions in the memory to cause the intelligent printing and typesetting device for printed materials based on screen printing and die-cutting technology to perform the various steps of the intelligent printing and typesetting method for printed materials based on screen printing and die-cutting technology as described in any of the preceding claims.

[0013] In the technical solution provided by this invention, an intelligent design system integrates user-inputted text and graphic elements, extracts coordinate data of the cutout areas through image processing algorithms, and converts the design file into a vector file suitable for screen printing to obtain a printing design draft. An electric screen tensioning machine controls the screen tension to the target value, and an automated coating machine applies a photosensitive emulsion layer. The cutout coordinate data from the design draft is imported into an exposure machine for precise positioning and exposure to obtain the screen printing plate. A rheometer measures the ink viscosity and dynamically adjusts the solvent ratio. A pressure sensor optimizes the squeegee angle, pressure, and speed parameters, and the adaptation parameters are input into the printing equipment to obtain a combination of printing parameters. A camera scans the printed material across the entire surface, and an image comparison algorithm extracts the location and type of defects.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in this specification means the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0022] Intelligent printing and layout methods for printed materials based on screen printing and die-cutting technologies, such as Figure 1 As shown, the process includes the following steps: An intelligent design system integrates user-inputted text and graphic elements, extracts coordinate data of the cutout areas using image processing algorithms, and converts the design file into a vector file suitable for screen printing to obtain the printing design draft; an electric screen tensioning machine controls the screen tension to the target value, an automated coating machine applies a photosensitive emulsion layer, and the cutout coordinate data from the design draft is imported into an exposure machine for precise positioning and exposure to obtain the screen printing plate; a rheometer measures the ink viscosity and dynamically adjusts the solvent ratio, a pressure sensor optimizes the squeegee angle, pressure, and speed parameters, and the adapted parameters are input into the printing equipment to obtain the printing parameter combination; a camera scans the printed material across the entire surface, and an image comparison algorithm extracts the defect location and type, feeding the quality inspection results back to the control system to automatically adjust the printing parameters, reprinting the defective areas until they are qualified, to obtain the printed product; a vision positioning system controls a cutting machine to complete irregular cutting, and a hot air drying method is selected according to the ink type to ensure complete ink curing; qualified and defective products are sent to different channels to obtain the finished printed product.

[0023] like Figure 2 As shown, in this embodiment, an intelligent design system is used to construct the interactive interface. Users can directly input text content and graphic elements. The system automatically vectorizes the input content and integrates it into a unified design layer. The outline of the hollow area in the design is extracted through edge detection and morphological analysis algorithms to obtain its coordinate position, line width and spacing parameters. The non-hollow parts are filled and optimized. The extracted hollow data is logically superimposed with the basic design file and converted into a vector format file that meets the requirements of screen printing process to obtain the printing design draft. The vector format file includes layered annotations of printing area and non-printing area information.

[0024] An intelligent design system is used to build the interactive interface, allowing users to easily input content. The system automatically vectorizes and integrates layers, improving design efficiency. Edge detection and morphological analysis algorithms accurately extract parameters for the cutout areas and optimize non-cutout parts, ensuring design precision. The cutout data is logically overlaid with the base file, converting it into a vector format file suitable for screen printing processes, including layered annotation information. This significantly reduces printing difficulty and error rates, providing strong support for high-quality screen printing design.

[0025] like Figure 3 As shown, in this embodiment, the tension sensor mounted on the electric wire mesh stretching machine monitors and dynamically adjusts the tensile force of the wire mesh frame in real time, precisely controlling the wire mesh tension to the required 18-25 N / cm. 2 Target values; using a laser rangefinder equipped with an automated coating machine to ensure that the photosensitive adhesive layer is coated on the screen surface with a uniform thickness of 5-8μm, and to complete the curing degree detection of the adhesive layer; the coordinate data of the cutout area extracted by the intelligent design system is imported into the digital exposure machine using an encrypted transmission module; the screen and the film are bonded with zero gap through a vacuum adsorption device, and UV light source is used for precise irradiation to obtain a screen printing plate with transparent cutout areas and ink-resistant non-cutout areas.

[0026] The electric screen stretching machine, equipped with a tension sensor, can monitor and adjust the stretching force in real time, precisely controlling the screen tension within the target range to ensure screen stability. The automated coating machine, using a laser rangefinder, ensures uniform coating of the photosensitive emulsion layer and completes curing degree detection, improving coating quality. The coordinate data of the cutout areas from the intelligent design system are encrypted and transmitted to the digital exposure machine. Combined with a vacuum adsorption device, the screen and film are bonded together with zero gap. Precise irradiation by a UV light source yields a high-quality screen printing plate, providing an excellent template for subsequent printing and effectively improving printing yield and quality.

[0027] like Figure 4 As shown, in this embodiment, the ink viscosity is detected in real time using a rheometer, and the current viscosity value is compared with the preset process range to dynamically calculate the required solvent addition ratio. The adjusted ink is then transported to a mixing device for homogenization. A high-precision pressure sensor array is used to monitor the pressure distribution, angle offset, and moving speed of the squeegee and screen contact surface. After extracting multi-dimensional parameters, the algorithm model is optimized to obtain the optimal printing pressure value, squeegee tilt angle, and running speed. The optimized parameter combination is transmitted to the printing equipment control module via an industrial bus to drive the mechanical unit to automatically calibrate and obtain a standardized printing parameter combination.

[0028] By using a rheometer to monitor ink viscosity in real time, comparing it with a preset range, and calculating the solvent addition ratio, ink performance is precisely controlled to ensure stable printing quality. The adjusted ink is then homogenized, and a high-precision pressure sensor array monitors multi-dimensional parameters of the squeegee-screen contact surface. Algorithm models are used to optimize these parameters, obtaining the best printing parameters. Finally, the optimized parameters are transmitted to the equipment control module via an industrial bus, driving the mechanical unit to automatically calibrate. This series of operations effectively reduces variable interference during the printing process, significantly improves the standardization of printing and product consistency, and reduces the scrap rate.

[0029] like Figure 5 As shown, in this embodiment, a high-speed industrial camera is used to perform a full-width, no-dead-angle scan of the printed material to obtain complete image data of the printed surface. An image comparison algorithm is used to perform pixel-level comparison between the real-time scanned image and a standard template to extract the coordinates, shape features, and defect type information of the defect area. The quality inspection results are fed back to the central control module of the printing equipment via an encrypted communication module. Based on the defect type, a preset parameter adjustment strategy is automatically invoked to drive the real-time correction of the squeegee pressure, ink supply, and printing speed. The corrected defect area is then reprinted. This process, from image scanning, defect extraction through comparison, parameter adjustment, to reprinting, continues until the quality inspection module determines that the image and template match meets the standards, resulting in the printed material.

[0030] High-speed industrial cameras are used to scan printed materials across the entire surface, acquiring complete image data and capturing every minute detail. Pixel-level comparison using image contrast algorithms accurately extracts defect information, providing a basis for subsequent corrections. The quality inspection results are encrypted and fed back to the central control module, which automatically applies adjustment strategies based on the defect type, adjusting parameters such as squeegee pressure in real time to achieve intelligent error correction. The corrected defective areas are then reprinted, and this process is repeated until the matching accuracy meets the standards. This process significantly improves printed quality, reduces manual intervention, increases production efficiency, effectively reduces the defect rate, and ensures product consistency.

[0031] In this embodiment, a high-precision visual positioning system scans the printed matter in real time, extracts its edge contour and feature point coordinate data, generates irregular cutting paths, and transmits them to a CNC cutting machine. Based on the ink composition analysis results, a hot air circulation drying device specifically designed for solvent-based inks is automatically selected, and temperature and light intensity control ensures complete ink curing. A photoelectric sensor is used to perform secondary quality inspection on the printed matter, extracting surface flatness and color consistency indicators. Qualified products and defective products are guided to different sorting channels to obtain finished printed matter with precise edges and complete ink curing.

[0032] A high-precision visual positioning system scans printed materials in real time, accurately extracting edge and feature point data to generate irregular cutting paths, ensuring precise cutting edges. Based on ink composition analysis, it automatically selects appropriate drying equipment, ensuring complete ink curing through precise control of temperature and light intensity. A photoelectric sensor performs secondary quality inspection, extracting key indicators such as surface flatness and color consistency, strictly controlling quality. Qualified and defective products are sorted into different channels, effectively differentiating product grades. The entire process improves the cutting accuracy, curing effect, and quality stability of printed materials, increasing production efficiency and product qualification rate.

The system dynamically adjusts the viscosity and solvent ratio, uses a pressure sensor to optimize the scraper angle, pressure, and speed parameters, and inputs these parameters into the printing equipment to obtain a combination of printing parameters. The quality inspection module uses a camera to scan the printed material across the entire surface, extracts the location and type of defects through image comparison algorithms, and feeds the inspection results back to the control system to automatically adjust printing parameters, reprinting defective areas until they are acceptable, thus obtaining the final printed product. The finished product sorting module uses a vision positioning system to control the cutting machine to complete irregular-shaped cutting, selects the hot air drying method according to the ink type to ensure complete ink curing, and sorts qualified and defective products into different channels to obtain the finished printed product.
