Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing technology, and in particular to a curing light source power control method, device, equipment and storage medium. BACKGROUND

[0002] In an industrial inkjet printing system, in order to improve the quality and gloss of the printed product, the printed product is printed using resin material (UV ink), and a layer of varnish is also sprayed on the surface. This not only improves the gloss of the product, but also prevents the printed product surface from discoloring and scratching, so that the printed product surface is smoother, the color is more saturated, the image is more delicate, and it has a more senior feel.

[0003] Resin material and varnish are difficult to volatilize and dry under natural conditions. In order to accelerate curing, a curing light source (usually a UV curing lamp) is used for irradiation to quickly cure the resin material and varnish. In the prior art, the power of the curing light source is constant or divided into several levels, but in the actual printing process, the power of the curing light source cannot be dynamically adjusted according to the actual situation of the current printing environment. The high or low power of the curing light source affects the ink curing efficiency. If the power is too low, the ink may not be completely cured after scanning, and if the power is too high, the ink may be cured before it is completely fused, affecting the quality of the finished product. In addition, in the printer, the relative position offset between the installation position of the UV curing lamp and the position of the nozzle (there is a position offset error in the actual installation of different printers) will also cause deviation in the power adjustment during actual printing.

[0004] Some light source curing control technologies are also disclosed in the prior art, such as Comparative Document 1 (CN108891132A), which discloses an ink curing method comprising: obtaining the number of times of printing covering a specified area of a printing medium when ink is sprayed, the ink including pattern forming ink and transparent ink; determining a power variation law of a first light source irradiating the pattern forming ink according to the number of times of printing, the power variation law of the first light source being determined such that the power of the first light source is different when at least two of the number of times of printing cover the specified area of the printing medium; obtaining a relative position relationship between the printing medium and the nozzle, and determining a power variation law of a second light source irradiating the transparent ink according to the relative position relationship and the number of times of printing, the power variation law of the second light source being determined such that the power of the second light source is different when at least two of the number of times of printing cover the specified area of the printing medium; obtaining a first control signal for controlling the first light source according to the power variation law of the first light source, and obtaining a second control signal for controlling the second light source according to the power variation law of the second light source; controlling the first light source to irradiate and cure the pattern forming ink after spraying the pattern forming ink according to the first control signal, and controlling the second light source to irradiate and cure the transparent ink sprayed on the pattern forming ink according to the second control signal.

[0005] The contrastive document 2 (CN108891131A) discloses a transparent ink curing method, comprising: obtaining the printing times of covering the specified area of the printing medium when the transparent ink is jetted, and the relative position relationship between the printing medium and the nozzle; determining the power variation rule of the light source irradiating the transparent ink according to the printing times and the relative position relationship, and determining that the power of the light source is different when at least two of the printing times of covering the specified area of the printing medium are printed; obtaining a control signal for controlling the light source to emit light according to the power variation rule; and controlling the light source to irradiate and cure the transparent ink after the transparent ink is jetted according to the control signal.

[0006] The contrastive document 3 (CN108819499A) discloses an ink curing method for pattern formation, which comprises: obtaining the printing times of covering the specified area of the printing medium when the ink for pattern formation is jetted; then determining the power variation rule of the light source irradiating the ink for pattern formation according to the printing times, so that the power of the irradiating light source for curing the specified area of the printing medium is not completely the same each time; obtaining a control signal for controlling the light source to emit light according to the power variation rule; and controlling the light source to irradiate and cure the ink for pattern formation after the ink for pattern formation is jetted according to the control signal, and dynamically adjusting the power of the light source in real time according to the printing times, so that different color inks printed on the printing medium can be timely and completely cured, and the surface of the printed product is flat and free of yin and yang colors.

[0007] The above-mentioned prior art is all about dynamic adjustment of the power during ink curing. Generally, the power is adjusted during the printing process. However, when the above-mentioned prior art is used in different printing environments, the performance of the nozzle and the ink will deviate from the ideal state, and the dynamic adjustment according to the preset power variation rule will also deviate. In addition, the printing effect of the actual printed product is still not good. This is because there is no prior reference. For example, if the printing is carried out according to the power variation rule of a light source in a high-temperature printing environment or a low-temperature printing environment, the ink curing effect will be poor or the ink leveling time will be insufficient, which will affect the quality of the printed product. SUMMARY

[0008] Therefore, the embodiments of the present application provide a curing light source power control method, device, equipment and storage medium, to solve the technical problem that the power adjustment of the curing light source in the prior art does not consider the actual printing environment, resulting in poor curing effect of the actual printed product.

[0059] Embodiment 1

[0060] Please refer toFigure 1 The embodiment of the present application provides a curing light source power control method, characterized in that the method comprises:

[0061] S1, obtaining a first ink curing parameter value meeting a preset condition through at least one test printing picture;

[0062] S2, starting a curing light source used for curing the to-be-printed picture according to a preset curing light source power to obtain a plurality of second ink curing parameter values corresponding to printing the to-be-printed picture in an actual printing environment at a preset time interval;

[0063] S3, dynamically adjusting the power of the curing light source according to the first ink curing parameter value and the plurality of second ink curing parameter values;

[0064] Specifically, first, at least one test printing is performed to obtain a first ink curing parameter value meeting a preset condition, such as Figure 2 as shown, Figure 2 The printhead shown in the figure comprises four nozzle columns of C, M, Y and K, a sensor and a curing light source. The first ink curing parameter value can be obtained by the sensor installed on the printhead. In the printing process, the sensor moves together with the reciprocating scanning of the printhead, and the ink curing parameter value is collected in real time. The sensor comprises but is not limited to a high-definition camera, a line-scan camera and the like. Any sensor capable of obtaining a high-definition image can be used, which is not specifically limited here. When actual printing is performed, the curing light source is started according to a preset curing light source power to obtain a plurality of second ink curing parameter values in an actual printing environment at a preset time interval. The plurality of second ink curing parameter values in the actual printing environment are obtained in real time at a preset time interval in the printing process through the above-mentioned sensor. The power of the curing light source is dynamically adjusted according to the first ink curing parameter value and the plurality of second ink curing parameter values, so as to improve the curing effect of the printing finished product, and avoid the situation that the ink cannot be completely cured or the ink is cured without complete fusion due to too low or too high power, thereby improving the quality of the finished product.

[0065] In an embodiment, please refer to Figure 3 , the step S1 comprises:

[0066] S11, performing test printing to obtain a test printing picture at an initial curing light source power;

[0067] S12, obtaining an ink curing parameter value according to the test printing picture;

[0068] S13, increasing the initial curing light source power by a preset step value to obtain an intermediate curing light source power;

[0069] S14, performing test printing to obtain a corresponding test printing picture at the intermediate curing light source power, and further obtaining an ink curing parameter value;

[0070] S15, when the intermediate curing light source power is less than the preset maximum power, continue to increase by the preset step value, and each time the preset step value is increased, test printing is performed, and the corresponding ink curing parameter value is obtained;

[0071] S16, when the current intermediate curing light source power is greater than or equal to the preset maximum power through several times of preset step value increase, stop test printing;

[0072] S17, according to the preset condition, screen the first ink curing parameter value from all obtained ink curing parameter values;

[0073] Specifically, first, start the curing light source at an initial curing light source power, perform test printing, obtain a test print, obtain an ink curing parameter value according to the test print, then increase the initial curing light source power by a preset step value to obtain an intermediate curing light source power, perform test printing at the intermediate curing light source power to obtain a corresponding test print, further obtain an ink curing parameter value, when the intermediate curing light source power is less than the preset maximum power, continue to increase the intermediate curing light source power by the preset step value, each time the preset step value is increased, test printing is performed, and the corresponding ink curing parameter value is obtained, and the ideal ink curing data is obtained by screening the ink curing parameters that meet the preset screening condition from the plurality of ink curing data, wherein the preset step value can be set by the user, when the preset step value is too small, the number of test printing required is increased, ink and printing medium are wasted, and since the difference between each power is too small, it is difficult to distinguish the difference on the test print, which increases the difficulty of screening the ink curing parameter value, when the preset step value is too large, the ink curing parameter value with good curing effect is missed, and the curing effect of the finished product cannot reach the optimum;

[0074] In a specific embodiment, the initial curing light source power is 40%, the preset step value is 20%, and the preset maximum power is 100%. First, set the curing light source power to 20%, perform test printing, collect a first test print during the printing process, obtain a first ink curing parameter value according to the test print, at this time, the curing light source power is less than 100%, then set the curing power of the curing light source to 60%, perform test printing again and collect a second test print, further obtain a first ink curing parameter value according to the second test print, and so on, constantly obtain a first ink curing parameter value and adjust the power of the curing light source until the power of the curing light source reaches the preset maximum power, i.e. 100%, finally obtain a fourth test print, the first test print, the second test print, the third test print, and the fourth test print are as follows: Figure 4As shown, the ink curing data under different curing light source powers is obtained by the above four test printing images, and the first ink curing parameter value is screened from all the obtained ink curing parameter values according to the preset condition. The screening of the ink curing parameter can be performed by screening the test printing image with the best curing effect in the test printing images. For example, in the several test printing images shown, the ink curing effect of the fourth test printing image is the best, and the ink curing parameter value corresponding to the fourth test printing image is obtained as the first ink curing parameter value. Figure 4 As shown, the ink curing data under different curing light source powers is obtained by the above four test printing images, and the first ink curing parameter value is screened from all the obtained ink curing parameter values according to the preset condition. The screening of the ink curing parameter can be performed by screening the test printing image with the best curing effect in the test printing images. For example, in the several test printing images shown, the ink curing effect of the fourth test printing image is the best, and the ink curing parameter value corresponding to the fourth test printing image is obtained as the first ink curing parameter value.

[0075] In an embodiment, the step S12 comprises:

[0076] S121, finding a first boundary area between the ink curing area and the molten ink area in the test printing image, and selecting the ink curing area in the test printing image as a target test printing image;

[0077] S122, determining the actual starting position of the curing light source according to the first boundary area;

[0078] S123, determining the target starting position according to the preset starting position of the curing light source and the actual starting position;

[0079] S124, performing binaryzation processing on the target test printing image to obtain the ink curing parameter value;

[0080] Specifically, during the test printing, the printing image is cured by the light source in the inkjet printing process according to the preset curing light source power, and a test printing image is obtained. A first boundary area between the ink curing area and the molten ink area in the test printing image is found. The actual starting position of the curing light source can be determined according to the first boundary area. The target starting position is determined according to the preset starting position of the curing light source and the actual starting position. Due to circuit transmission delay or other reasons, the starting position of the curing light source may deviate from the preset starting position during printing. By determining the target starting position, the starting position of the curing light source can be corrected, and the curing effect of the to-be-printed image can be improved. The binaryzation of the image is beneficial to the further processing of the image, makes the image simple, reduces the data amount, and highlights the outline of the target. After the binaryzation processing, the ink curing parameter value can be obtained through feature extraction;

[0081] In an embodiment, the S2 comprises:

[0082] S21, performing actual printing in an actual printing environment, and obtaining several actual printing images at a preset time interval by starting the curing light source according to the preset curing light source power and the target starting position during the actual printing.

[0083] S22, find the junction areas of the solidified ink and the molten ink from the actual printing images to obtain a plurality of target actual printing images;

[0084] S23, perform a binaryzation process on the target actual printing images to obtain a plurality of second ink solidification parameter values;

[0085] Specifically, during actual printing, the actual printing is performed under an actual printing environment, and a plurality of actual printing images are obtained at a preset time interval during the actual printing by starting the solidification light source according to a preset solidification light source power and the target opening position. The preset time interval can be set by the user. Then, the junction areas of the solidified ink and the molten ink are found from the actual printing images to obtain a plurality of target actual printing images. A binaryzation process is performed on the target printing images to obtain a plurality of second ink solidification parameter values. The second ink solidification parameter values are obtained in the same manner as the first ink solidification parameter values, and thus will not be described herein again.

[0086] In an embodiment, referring to Figure 5 , the step S3 comprises:

[0087] S31, performing a weighted operation on the first ink solidification parameter values to obtain a first weight value;

[0088] S32, sequentially performing a weighted operation on the second ink solidification parameter values according to the order of obtaining the second ink solidification parameter values to obtain a plurality of second weight values;

[0089] S33, dynamically adjusting the power of the solidification light source according to the first weight value and the second weight values;

[0090] Specifically, after the first ink solidification parameter values and the second ink solidification parameter values are obtained, since the first ink solidification parameter values are obtained before the actual printing, a weighted operation is first performed on the first ink solidification parameter values to obtain a first weight value. The second ink solidification parameter values are obtained continuously during the actual printing. A weighted operation is performed on the second ink solidification parameter values to obtain a second weight value each time a second ink solidification parameter value is obtained. The power of the solidification light source is adjusted according to the first weight value and the second weight values. The corresponding second weight values are obtained by multiple second ink solidification parameter values. The power of the solidification light source is continuously adjusted during the actual printing to achieve a better ink solidification effect.

[0091] In a specific embodiment, the first ink curing parameter value and the second ink curing data parameter value include image brightness and image flatness, the image brightness is denoted as A, the image flatness is denoted as B, the first weight value and the second weight value are calculated by the following formula: a*A+β*B, and a and β are the weight of the image brightness and the weight of the image flatness, respectively, which can be set by the user according to the actual situation.

[0092] In an embodiment, the S33 comprises:

[0093] S331, in the actual printing process, the first weight value and the second weight value are compared in turn according to the acquisition order of the two weight values;

[0094] S332, when the first weight value is greater than the second weight value, the power of the curing light source is reduced according to the first preset value;

[0095] S333, when the first weight value is less than the second weight value, the power of the curing light source is increased according to the second preset value;

[0096] Specifically, in the actual printing process, the first weight value and the second weight value are compared in turn according to the acquisition order of the two weight values, when the first weight value is greater than the second weight value, it indicates that the power of the curing light source is too high at this time, which causes the ink to be cured before it is fully fused, at this time, the power of the curing light source is reduced according to the first preset value, when the first weight value is less than the second weight value, it indicates that the power of the curing light source is too low at this time, and the ink cannot be fully cured, at this time, the power of the curing light source is increased according to the second preset value, wherein the first preset value and the second preset value can be set by the user, which is not limited herein, by collecting the second ink curing parameter value in real time during the printing process, the first ink curing parameter value and the second ink curing parameter value are weighted and compared, the dynamic adjustment of the curing power in the printing process is realized, the curing efficiency is improved, and the product quality is improved.

[0097] In an embodiment, the method further comprises:

[0098] S4, after the actual printing is completed, a final printed image is collected;

[0099] S5, when the molten ink is found in the final printed image, an alarm signal is sent.

[0100] Specifically, after the curing ends, at this time the ink on the printed image is in an ideal state, the ink is completely cured, but in actual printing, due to or curing light source failure or preset curing light source power is too small, the curing light source power needs to be adjusted for a long time during printing, resulting in that the ink in the printed image after the final curing ends is not completely cured, therefore, after the actual printing curing ends, the printed image is collected to obtain a final printed image, when the molten ink is found in the final printed image, an alarm signal is sent, in this embodiment, the alarm signal is an acoustic signal or a light signal, to remind the user to check or adjust the preset curing light source power of the curing light source of the printer.
