[0011] The present application provides an adaptive printing control method and system for a plate-roll integrated printing device, aiming to solve the technical problem in the prior art that a flatbed printer and a guide belt printer in UV printing equipment cannot meet the requirements of composite functions. The plate-roll integrated printing device supports both flatbed printing and coil printing functions, and the adaptive printing control method dynamically optimizes printing parameters, thereby achieving the technical effect of improving printing efficiency and flexibility.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0013] It should be noted that any variations of the terms "include" and "have" are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules that are not explicitly listed or inherent to these processes, methods, products or devices.

[0014] Embodiment 1, as Figure 1 As shown, the present application provides an adaptive printing control method for a plate-roll integrated printing device, the method comprising: Step S100: obtaining a target printing requirement, and switching a target printing mode according to the target printing requirement.

[0015] In the embodiment of the present application, the pre-entered target printing requirement is first obtained, and the target printing requirement is analyzed, that is, the type of printing medium is identified. If the target printing requirement is "roll printing", that is, the printing object is a continuous roll material, the device will switch to "guide belt printing mode". If the target printing requirement is "flatbed printing", that is, the printing object is a flatbed material of fixed size, the device will switch to "flatbed printing mode".

[0016] Furthermore, in the method provided in the embodiment of the application, the target printing requirement is obtained, and the target printing mode is switched according to the target printing requirement, and further includes: If the target printing requirement is flatbed printing, the target printing mode is switched to flatbed printing mode; in the flatbed printing mode, the table and conveyor belt in the plate-roll integrated printing device remain stationary, and the crossbeam moves to achieve the flatbed printing; wherein, the flatbed printing mode refers to turning off the belt drive motor in the plate-roll integrated printing device and starting the Y-axis guide motor in the plate-roll integrated printing device.

[0017] In an embodiment of the present application, when the target printing requirement is flatbed printing, the target printing mode of the plate-roll integrated printing device is switched to flatbed printing mode.

[0018] In flatbed printing mode, the table and conveyor belt in the plate-roll printing device remain stationary. The table is a structural platform for carrying the printing medium, and the conveyor belt is a flexible covering layer originally used for coil material transportation. In this mode, these two parts do not move at all, providing a stable support environment for the printing medium, avoiding displacement or vibration during the printing process, and ensuring accurate picture position and clear image edges.

[0019] At the same time, the crossbeam of the plate-roll integrated printing device starts to move, so that the print head can scan and print relative to the medium. As a key component for installing the print head, the crossbeam moves smoothly on the guide rail along the Y-axis direction, allowing the print head to cover the entire plate format line by line. This method corresponds to the structural logic of traditional flatbed printers, that is, keeping the medium stationary and the print head moving to ensure high-resolution output and consistency of the printed pattern.

[0020] Specifically, the flatbed printing mode means turning off the belt drive motor in the plate-roll integrated printing device to stop the transmission mechanism; at the same time, starting the Y-axis guide motor to drive the beam to move on the guide to complete the printing action. This motor controls the reciprocating motion of the beam along the Y-axis direction and is the key power source for scanning and printing.

[0021] Furthermore, in the method provided in the embodiment of the application, the target printing requirement is obtained, and the target printing mode is switched according to the target printing requirement, and further includes: If the target printing requirement is roll-to-roll printing, the target printing mode is switched to guide belt printing mode; in the guide belt printing mode, the table and conveyor belt in the plate-roll integrated printing device keep moving, while the crossbeam is stationary, to achieve the roll-to-roll printing; wherein, the guide belt printing mode refers to starting the belt drive motor in the plate-roll integrated printing device and turning off the Y-axis guide motor in the plate-roll integrated printing device.

[0022] In the embodiment of the present application, after it is determined that it is roll printing, the device performs a mode switching operation to switch the target printing mode to the belt printing mode. First, the belt driving motor is started. This motor is connected to the driving rollers arranged at the front and rear of the equipment table, and the driving rollers are covered by a layer of flexible belt. After the belt driving motor runs, it drives the conveyor belt to move continuously along the Y-axis direction, thereby pushing the roll material to pass through the printing area along a predetermined path, realizing the continuous conveyance of the long medium. The conveyor belt here undertakes the same function as the mesh belt in a traditional belt printer. However, due to the use of belt material, it has better flatness than the traditional mesh belt when supporting flat printing.

[0023] At the same time, to ensure that the nozzle can stably output the pattern during the movement of the continuous medium, the device turns off the Y-axis guide rail motor to keep the crossbeam carrying the nozzle stationary. The crossbeam serves as the fixed bracket for the nozzle and does not participate in the movement. The nozzle completes the printing process through the relative movement with the moving medium at a fixed position.

[0024] In the belt printing mode, the tabletop of the device and the conveyor belt are always in a moving state, jointly completing the feeding and stable carrying of the medium; while the crossbeam remains stationary to reduce the offset error that may occur when the nozzle runs at high speed, thereby improving the stability and consistency of the output pattern.

[0025] Through the above steps, the sheet-roll integrated printing device realizes a smooth transition from the flat printing logic to the belt printing logic in the scenario where a roll material is required.

[0026] Further, in the method provided by the application embodiment, the sheet-roll integrated printing device further includes: Obtain the tabletop of the target printing device; arrange driving rollers at the first preset position of the tabletop, and cover the driving rollers with the conveyor belt; form a flat printing structure based on the driving rollers, the conveyor belt and its belt driving motor; obtain the crossbeam of the target printing device; install the Y-axis guide rail motor at the second preset position of the crossbeam; form a belt printing structure based on the crossbeam and the Y-axis guide rail motor; configure the sheet-roll integrated printing device by combining the flat printing structure and the belt printing structure.

[0027] In the embodiment of the present application, first, the tabletop of the printing device is obtained, and this tabletop serves as the basic platform for supporting the printing medium. At the first preset positions of the tabletop, namely, the two ends close to the feeding and discharging directions, driving rollers are arranged. The driving rollers serve as the transmission core and are used to drive the movement of the belt. Subsequently, a conveyor belt is covered on the driving rollers. This belt is made of flexible material to adapt to the conveying requirements of different types of media. Through the linkage combination of the driving rollers, the conveyor belt and the belt driving motor connected thereto, a structure with transmission ability is formed, which can provide a stable platform to support static flat printing in the stopped state and can also realize the continuous conveying of the coil material in the running state, thus constituting a complete flat printing structure.

[0028] Then, the crossbeam part of the printing device is obtained. The crossbeam spans across the entire tabletop area and is the installation carrier for the print head and the execution components. At the second preset position of the crossbeam, a Y-axis guide rail motor is installed. This motor is connected to the guide rail system and drives the crossbeam to reciprocate in the Y-axis direction to realize the line-by-line scanning of the medium by the print head. Through the cooperation of the crossbeam and the Y-axis guide rail motor, a belt-guided printing structure is constructed to complete the precise printing task when the print head needs to move, meeting the requirement of high-quality pattern output under static media.

[0029] Finally, the foregoing flat printing structure and the belt-guided printing structure are combined functionally to complete the configuration of the flat-coil integrated printing device. By controlling the start-stop states of the belt driving motor and the Y-axis guide rail motor, the device can freely switch between the flat printing mode and the coil printing mode to realize the intelligent adaptation to different printing media. Based on inheriting the technical characteristics of traditional flatbed printers and belt-guided printers, this design integrates the structural advantages of both to improve the versatility, applicability and resource utilization efficiency of the device.

[0030] Step S200: Activate the sensor assembly and perform dynamic feature monitoring on the target printing material through the sensor assembly to obtain target material parameters.

[0031] In the embodiment of the present application, first, the ink state is monitored by activating the sensor assembly to obtain ink characteristic parameters including position, speed, etc.; then the paper is monitored to extract paper characteristic parameters such as thickness, flatness, ink absorbency and elastic modulus. Finally, the ink characteristic parameters and the paper characteristic parameters are integrated to construct complete target material parameters.

[0032] Furthermore, in the method provided by the application embodiment, activating the sensor assembly and performing dynamic feature monitoring on the target printing material through the sensor assembly to obtain target material parameters further includes: Monitoring the target ink in the target printing material through the sensor component to obtain ink characteristic parameters; monitoring the target paper in the target printing material through the sensor component to obtain paper characteristic parameters; and constructing the target material parameters according to the ink characteristic parameters and the paper characteristic parameters.

[0033] Further, the method provided by the application embodiment further includes: The ink characteristic parameters at least include ink position and ink speed.

[0034] Further, the method provided by the application embodiment further includes: The paper characteristic parameters at least include paper thickness, paper flatness, paper ink absorbency, and paper elastic modulus.

[0035] In the embodiment of the present application, first, the target ink in the target printing material is monitored through the sensor component to obtain ink characteristic parameters. Among them, the ink characteristic parameters at least include ink position and ink speed. Specifically, when monitoring the target ink, a high-speed vision sensor is used to capture images of the inkjet process, and image processing algorithms (such as centroid detection and trajectory analysis) are used to identify the specific coordinates of the ink droplets in space. The ink position refers to the three-dimensional spatial position of the ink droplets during ejection, represented by a rectangular coordinate system (X, Y, Z) relative to the origin of the nozzle of the print head. For example, at a certain ejection moment, the detected spatial coordinates of the ink droplet are (12.35mm, 4.12mm, 1.85mm), which is the ink position of the ink droplet.

[0036] To obtain the ink speed, record the displacement of the ink droplet in two consecutive frames of images and the corresponding time interval. Let the position of the ink droplet in frame 1 be , and the position in frame 2 be , then the displacement of the ink droplet , if the image frame rate is f frames per second, the time interval is Δt = 1 / f, and the corresponding ink speed is calculated as v = d / Δt. Through this calculation process, the ink characteristic parameters are obtained.

[0037] Subsequently, the target paper in the target printing material is monitored through the sensor component to obtain paper characteristic parameters, where the paper characteristic parameters at least include paper thickness, paper flatness, paper ink absorbency, and paper elastic modulus. Measure the paper thickness by using a laser displacement sensor. Record the height from the sensor to the platform as in the paperless state, and record the new height as after the paper is placed, then the paper thickness is . To obtain the paper flatness, collect height data at multiple points on the paper surface , calculate their average value, and then calculate the standard deviation. The calculated standard deviation is used as the paper flatness.

[0038] The ink absorbency of the paper is obtained through a diffusion test. A standard ink droplet volume (such as 0.1 μL) is dropped on the paper surface, and the diffusion area A within a unit time t is recorded using a vision system. The ink absorbency is calculated as S = A / t.

[0039] To obtain the elastic modulus of the paper, a standard stress σ is applied to the paper using a loading platform, and its unit strain ε = ΔL / where ΔL is the deformation amount of the paper, is the initial length of the paper, and the elastic modulus E is E = σ / S. The elastic modulus of the paper is obtained through calculation.

[0040] Finally, based on the ink characteristic parameters and the paper characteristic parameters, the target material parameters are formed. These parameters consist of six quantitative indicators: ink position, ink speed, paper thickness, paper flatness, paper ink absorbency, and paper elastic modulus.

[0041] Furthermore, in the method provided by the application embodiment, before obtaining the first print record corresponding to the first print parameters in the target print mode with the target material parameters as the print constraint, it further includes: Dynamically monitoring to obtain environmental characteristic parameters and adding the environmental characteristic parameters to the print constraint; wherein, the environmental characteristic parameters at least include temperature, humidity, and air quality.

[0042] In the application embodiment, first, the characteristic parameters such as temperature, humidity, and air quality in the environment are monitored in real time through environmental sensors. Specifically, the real-time temperature of the environment is detected through a temperature sensor preset on the printing device, the relative humidity in the air is monitored through a humidity sensor, and the particulate matter concentration in the air is measured through an air quality sensor to obtain the environmental characteristic parameters. The environmental characteristic parameters at least include real-time temperature, humidity, and air quality.

[0043] Finally, the environmental characteristic parameters obtained through dynamic monitoring are added to the print constraint.

[0044] Step S300: Using the target material parameters as the print constraint, obtain the first print record corresponding to the first print parameters in the target print mode.

[0045] In the application embodiment, the dynamic characteristic monitoring of the target printing material has been carried out through the sensor assembly to obtain the target material parameters, which include ink characteristic parameters (such as ink position, ink speed) and paper characteristic parameters (such as paper thickness, paper flatness, paper ink absorbency, paper elastic modulus). In addition, the environmental characteristic parameters (such as temperature, humidity, and air quality) will also be integrated into the print control as one of the print constraints.

[0046] Next, based on the obtained target material parameters and the selected target printing mode, obtain the first printing parameters. The first printing parameters include specific operation settings such as nozzle voltage, ink flow rate, printing speed, etc. On this basis, perform an actual printing according to the first printing parameters, and record the data and feedback results during this printing process to form the first printing record. The first printing record includes the first printed product parameters, which are used to evaluate the quality of the printing effect. The first printed product parameters at least include the first step effect coefficient and the first light uniformity coefficient. These two coefficients are obtained by analyzing the printed image. Among them, the first step effect coefficient is used to measure whether the transition of color levels in the printed image is smooth, and it is calculated by analyzing the brightness difference between adjacent color blocks in the image. Specifically, select several color level boundaries in the image, and calculate the step effect coefficient by measuring the brightness difference between adjacent color levels. A higher brightness difference indicates a stronger step effect, while a smaller difference indicates a smooth color level transition. This coefficient can be quantified as the slope of the spectral curve of the color block transition. The smoother the transition, the lower the step effect coefficient. Assume that the adjacent color levels in the image have brightness values to , then the difference in the step effect is . If there are 5 color levels in the image, with brightness differences , then the step effect coefficient is their average value, step effect coefficient = (20 + 18 + 15 + 22 + 19) / 5 = 18.8.

[0047] The first light uniformity coefficient is used to evaluate whether the brightness of the printed image is uniform, avoiding areas with too high or too low brightness. Measure the brightness values in different areas of the printed image and calculate the standard deviation of the brightness distribution in the image. The smaller the standard deviation, the more uniform the illumination and the more consistent the brightness distribution of the image. This coefficient is obtained by calculating the difference between the brightness of each pixel in the image and the average brightness of the area. The final result represents the consistency of the image brightness. Assume that the brightness values of multiple measurement points in the image are , , calculate the average value of these brightnesses , then, calculate the brightness standard deviation. Square the difference between each brightness value and the average value and sum them up to obtain the brightness standard deviation. Take the brightness standard deviation as the light uniformity coefficient.

[0048] Step S400: Analyze the first printing record to obtain the first printing fitness of the first printing parameters.

[0049] In the embodiments of the present application, first, a first printing model is constructed based on the first printing product parameters (such as the step effect coefficient and the illumination uniformity coefficient) in the first printing record, and this model reflects the characteristics of the actual printing result. Then, a predetermined printing model is obtained, which represents the best printing effect under ideal conditions. Next, by comparing the first printing model with the predetermined printing model, the first similarity between the two is calculated, and this similarity measures the difference between the actual printing and the ideal printing. Finally, the first similarity is normalized to obtain a first printing fitness.

[0050] Further, in the method provided by the application embodiments, when analyzing the first printing record to obtain the first printing fitness of the first printing parameters, it further includes: Constructing a first printing model according to the first printing product parameters in the first printing record; obtaining a predetermined printing model, and comparing the predetermined printing model with the first printing model to obtain the first similarity; normalizing the first similarity to obtain the first printing fitness; wherein, the first printing product parameters at least include a first step effect coefficient and a first illumination uniformity coefficient.

[0051] In the embodiments of the present application, when constructing the first printing model according to the first printing product parameters in the first printing record, first, the first printing product parameters in the first printing record are extracted, including the first step effect coefficient and the first illumination uniformity coefficient . To construct the first printing model, the feature vector method is adopted, and these two parameters are used as the main feature dimensions of the model to construct a model expression in the form of a two-dimensional vector. For example, let the first step effect coefficient be , and the first illumination uniformity coefficient be , then the first printing model can be expressed as the feature vector .

[0052] Subsequently, a predetermined printing model is obtained, that is, the target model constructed under ideal printing conditions. This model is obtained through prior experiments or calibration processes, and is also structurally expressed using the feature vector method, including the step effect coefficient and the illumination uniformity coefficient under ideal conditions, forming the vector . This model serves as a standard reference for evaluating the actual printing effect and provides a comparison benchmark for subsequent similarity evaluation.

[0053] After obtaining the two printing models, the predetermined printing model is compared with the first printing model to obtain the first similarity. This process uses the Euclidean distance method to calculate the similarity. Specifically, calculate the two model vectors and the Euclidean distance D therebetween, and then convert the distance value into a similarity index in the form of wherein, the closer the similarity is to 1, the closer the two models are, that is, the closer the actual printing effect is to the ideal state.

[0054] Finally, normalize the first similarity to obtain the first printing fitness. The normalization adopts the linear normalization method to map the similarity value to the interval [0, 1].

[0055] Step S500: Take the maximum of the first printing fitness as the optimization goal to obtain the optimal printing parameters, and perform printing control for the target printing requirement according to the optimal printing parameters.

[0056] In the embodiment of the present application, randomly select different combinations of printing parameters (such as nozzle voltage, ink flow rate, printing speed, etc.) with the maximum of the first printing fitness as the optimization goal, and then perform simulated printing for each parameter combination. The simulated printing does not perform actual printing, but quickly predicts the printing effect under the current parameter combination through an image generation algorithm or a virtual simulation method. In this way, large-scale actual printing tests are avoided. After each simulated printing, extract the first printed product parameters from the printing result, and these parameters include the first step effect coefficient and the first light uniformity coefficient.

[0057] Subsequently, through the same process as described above, compare the current printing model with the predetermined printing model, and calculate the first similarity. Then normalize the first similarity to convert it into the first printing fitness. At this time, the fitness values of each group of printing parameters have been calculated based on the simulation results and the similarity. Take the maximum of the first printing fitness as the optimization goal, select the parameter combination with the maximum fitness value from multiple groups of printing parameter combinations, and use it as the optimal printing parameters.

[0058] Finally, perform actual printing control according to the obtained optimal printing parameters.
