Description
Technical Field
The invention relates to the technical field of printing, in particular to a power adjusting method, a power adjusting device, power adjusting equipment and a storage medium of a UV lamp.
Background
The UV Printer (Ultraviolet LED Inkjet Printer) performs printing by adopting UV (Ultraviolet, UV for short), UV ink is cured under the radiation of Ultraviolet light emitted by a UV lamp, and the obtained printing product has the advantages of clean plate surface, saturated color, delicate image, high glossiness, particular suitability for high-speed printing, and good adsorption performance and mechanical performance for various printing media. Therefore, UV printing is widely used today.
In the prior art, a UV lamp is usually used to perform undifferentiated irradiation on UV ink on a printing medium, that is, all light sources on the UV lamp use the same power to perform irradiation on the UV ink on the whole printing medium, but because the ink amount of each printing area on the printing medium is different, the technical scheme of undifferentiated irradiation causes different degrees of curing of the UV ink, so that the image quality on the printing medium is not uniform, that is, there is a technical problem of a curing channel.
Disclosure of Invention
In view of the above, embodiments of the present invention provide a method, an apparatus, a device and a storage medium for adjusting power of a UV lamp, so as to solve the technical problem of the curing track in the prior art to a certain extent.
In a first aspect, an embodiment of the present invention provides a power adjustment method for a UV lamp, the UV lamp including a plurality of light sources, the UV lamp being configured to illuminate at least 1 printing area, the method including:
s10: acquiring printing parameters, and determining the printing ink amount of each printing area according to the printing parameters;
s20: determining a power weight of each light source to each printing area according to a distance between each light source and each printing area;
s30: and determining the output power of each light source according to the power weight of each light source to each printing area and the printing ink amount of each printing area.
The embodiment of the invention determines the printing ink amount of each printing area through the printing parameters, determines the power weight of the light source to the printing area according to the distance between the light source and the printing area, and finally determines the output power of each light source according to the printing ink amount and the power weight. Because the printing ink amount of each printing area is different, the output power of each light source of the UV lamp is adjusted according to the printing ink amount of each printing area in the embodiment of the invention, and the printing areas with different printing ink amounts are cured by adopting different output powers in the curing process, so that although the printing ink amount of each printing area is different, the output power of each light source of the UV lamp can be mutually matched with the printing ink amount of each printing area, and thus, each printing area is cured accurately, the curing degree of the printing ink of each printing area can be close to the ideal degree to the maximum extent, the curing channel is inhibited, and the quality of a printed product is greatly improved. In addition, because the distances between the light sources and the printing areas are different, the output power of each light source of the UV lamp in the embodiment of the invention is adjusted according to the distance between each light source and the printing area, and the printing areas with different distances from the light sources are cured by adopting different output powers in the curing process, so that although the distances between the light sources and the printing areas are different, the output power of each light source of the UV lamp can be matched with the distance between each printing area and the light source, and thus, each printing area is cured accurately, the curing degree of the ink in each printing area can be close to the ideal degree to the maximum extent, the curing channel is inhibited, and the quality of the printed products and the like are greatly improved.
Preferably, in S20, the method further includes:
s21: acquiring a weight threshold;
s22: comparing the power weight to the weight threshold in magnitude;
s23: adjusting the power weight less than or equal to the weight threshold to zero.
As described above, the power weight of the light source with respect to the printing area is different depending on the distance between the light source and the printing area, and in general, the longer the distance between the light source and a certain printing area is, the smaller the power weight of the light source with respect to the printing area is, and when the power weight is equal to or less than the weight threshold value, the longer the distance between the printing area and the light source is, that is, when curing is performed, the radiation effect of the light source with respect to the printing area is weak, and when the determination of the output power is performed by introducing the printing area, it is determined that the obtained output power has a large error with respect to the other printing areas. Therefore, in order to avoid the large influence of the printing area on the determination of the output power of the light source, the embodiment of the invention compares the power weight with the weight threshold value, and adjusts the power weight smaller than or equal to the weight threshold value to zero, so that the output power of the light source is determined without introducing the printing area, and the error of the output power relative to other printing areas is reduced.
Preferably, in S20, the method further includes:
s24: obtaining a distance threshold;
s25: comparing the distance between each light source and each printing area with the distance threshold value in size;
s26: if the distance between the light source and the printing area is smaller than the distance threshold, determining the power weight according to the distance; and if the distance between the light source and the printing area is larger than or equal to the distance threshold value, skipping the step of determining the power weight according to the distance.
As described above, if the distance between the printing area and the light source is long, the radiation effect of the light source on the printing area is weak, and if the output power is determined by introducing the printing area, the determined output power has a large error with respect to other printing areas. Therefore, the embodiment of the invention compares the distance between the light source and the printing area with the distance threshold value, and when the distance between the light source and the printing area is greater than or equal to the distance threshold value, the step of determining the power weight according to the distance is skipped, so that the output power of the light source is determined without introducing the printing area, and the error of the output power relative to other printing areas is reduced. Meanwhile, the process of determining the power weight by the distance is reduced, and the efficiency is improved.
Preferably, the UV lamp includes n light sources, the UV lamp is used to illuminate m printing areas, n and m are positive integers, and in S20, the power weight satisfies a first conversion formula:
wherein, WijRepresenting the power weight of the jth light source for the ith print zone, dijAnd the distance between the jth light source and the ith printing area is expressed, A and k are positive real numbers, k is more than or equal to 1, i and j are positive integers, i is more than or equal to 1 and less than or equal to m, and j is more than or equal to 1 and less than or equal to n.
According to the embodiment of the invention, the power weight is determined according to the distance between the light source and the printing area through the first conversion formula, so that different distances are ensured to correspond to different power weights, and in the subsequent processing, the output power determined according to the power weight has more accurate adaptation degree to the distance between the light source and the printing area, so that the curing channel is further inhibited, and the printing effect is improved.
Preferably, the UV lamp includes n light sources, the UV lamp is used to irradiate m printing areas, n and m are positive integers, and in S30, the output power of the light source satisfies a second conversion formula:
wherein, PjDenotes the output power of the jth light source, DiIndicating the amount of printing ink, W, of the ith printing regionijAnd the power weight of the jth light source to the ith printing area is represented, i and j are positive integers, i is more than or equal to 1 and less than or equal to m, and j is more than or equal to 1 and less than or equal to n.
According to the embodiment of the invention, the output power of the light source is determined by the power weight of the light source to m printing areas and the printing ink amount of the m printing areas through a second conversion formula, so that the output power of the light source is determined by the m printing areas together (when the power weight of the light source to the m printing areas is not 0), and the output power of the light source can be better adapted to the m printing areas, so that the curing channel is further inhibited, and the printing effect is improved.
Preferably, the UV lamp includes n light sources, n being a positive integer, and in S30, the output power of the light sources satisfies a third conversion formula:
Pj＝Dj_near*Wj_near
wherein, PjDenotes the output power of the jth light source, Dj_nearIndicating the amount of printing ink, W, of the printing area nearest to the jth light sourcej_nearAnd j is a positive integer and is more than or equal to 1 and less than or equal to n.
As mentioned previously, the light source has the strongest radiation effect on the print area closest to it during curing. In other words, the curing effect of a certain printed area depends mainly on the output power of the light source closest thereto. Therefore, the embodiment of the invention determines the output power of the light source by the printing area closest to the light source through the third conversion formula, so that the output power of each light source is determined by the printing area closest to the light source, the output power of each light source is better adapted to the printing ink amount of the printing area closest to the light source, the curing degree of the ink in each printing area can be close to the ideal degree to the maximum extent, the curing channel is inhibited, and the quality of the printed product is greatly improved.
Preferably, in S10, the method includes:
s11: fitting the printing ink amount of each printing area to obtain a fitting curve or a fitting straight line;
s12: and re-determining the printing ink amount of each printing area according to the fitted curve or the fitted straight line.
The embodiment of the invention obtains a fitted curve or a fitted straight line by fitting the printing ink amount of each printing area, redetermines the printing ink amount of each printing area according to the fitted curve or the fitted straight line, and determines the output power according to the redetermined printing ink amount in subsequent processing, so that the determined output power can be well adapted to different printing areas with larger printing ink amount difference, thereby further inhibiting the curing channel and improving the printing effect.

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

Referring to fig. 1, a schematic diagram of UV lamp curing ink on a plurality of print areas is shown.
The printing medium 120 includes a plurality of printing areas, which are a printing area 1, a printing area 2, and a printing area 3, respectively.
The head 130 is used to eject ink on the printing medium 120, and the head 130 includes 9 nozzles, and for convenience of description, the head is numbered in its height direction (i.e., the top-to-bottom direction shown in fig. 1). Among them, nozzles No. 1 to 3 eject ink in the print area 1, nozzles No. 4 to 6 eject ink in the print area 2, and nozzles No. 7 to 9 eject ink in the print area 3.
The UV lamp 110 includes a plurality of light sources, respectively, a light source 1, a light source 2, a light source 3, and a light source 4. The 4 light sources are used to emit light of a characteristic wavelength (typically invisible light, such as ultraviolet) to irradiate the ink on the print medium 120 to achieve the technical effect of varnish curing.
In most application scenarios, the amounts of printing ink on the printing areas 1, 2, and 3 are not equal, but in the prior art, the 3 printing areas are uniformly irradiated in a non-differential irradiation manner, that is, the light source 1, the light source 2, the light source 3, and the light source 4 irradiate the 3 printing areas with equal output power, which causes a technical problem that the ink curing degrees of the 3 printing areas are different, resulting in uneven printing quality on the printing medium 120, that is, a curing channel exists. Meanwhile, the prior art generally drives the UV lamp with the maximum output power, and the energy consumption is large.
In view of the above, the present invention provides a method, an apparatus, a device and a storage medium for adjusting power of a UV lamp, so as to solve the technical problem of the curing track to a certain extent.
Referring to fig. 2, a flow chart of a power adjustment method of a UV lamp according to an embodiment of the present invention is shown, the method includes the following steps.
S10: acquiring printing parameters, and determining the printing ink amount of each printing area according to the printing parameters;
s20: determining a power weight of each light source to each printing area according to a distance between each light source and each printing area;
s30: and determining the output power of each light source according to the power weight of each light source to each printing area and the printing ink amount of each printing area.
Wherein the UV lamp comprises a plurality of light sources, the UV lamp for illuminating at least 1 printing area.
The printing parameters include one or more of image dot matrix data, printing mode, feathering height, stepping distance.
The printing modes include an Onepass printing mode, a multi-Pass scan printing mode, and a single-Pass scan printing mode.
The multi-Pass scanning printing means that each unit for printing an image can be printed only by performing interpolation for multiple times, each unit consists of a plurality of pixel points, if 2-Pass scanning printing is performed, each unit consists of 2 pixel points, and if 3-Pass scanning printing is performed, each unit consists of 3 pixel points. The multi-Pass scanning printing has low efficiency and small yield, but the price is cheap, so that the multi-Pass scanning printing method is suitable for small-batch and intermittent production. The wide-width printing product is realized by jet splicing or continuous multi-Pass printing. The multiple-Pass scanning printing mode is further divided according to the number of times of printing the same area by the nozzle, i.e. the Pass number, for example, a 2-Pass printing mode in which printing is completed by scanning 2 times, a 4-Pass printing mode in which printing is completed by scanning 4 times, and the like.
Single Pass scan printing means that each unit of a printed image requires only one scan to print.
Oneepass printing refers to that a plurality of spray heads scan side by side to complete one-time printing of a printed image. Oneeglass printing has the advantages of high efficiency and large output, and is suitable for a large-batch and continuous production mode.
Unless otherwise specified, the single scan printing referred to herein means that the head performs one scan printing. For example, in the 4Pass printing mode, the 1 st Pass printing or the 2 nd Pass printing process is a single scan printing process. If the Oneepass printing is adopted, the single-scanning printing indicates that the sprayer completes the process of printing the image by one-time scanning.
The printhead ejects ink onto a print medium to form a corresponding printed image while moving in a scan direction (typically orthogonal to the printhead height direction) during a single scan printing process. Therefore, the printing ink amount of each printing area can be determined according to the printing mode, the ink output amount of each nozzle and the corresponding relation between each nozzle in the nozzle and the printing area. Wherein the ink discharge amount of each nozzle can be determined by the image dot matrix data. In particular, if the feathering process is further performed, the ink discharge amount of each nozzle can be determined from the image dot matrix data and the feathering height. The printing ink amount of the printing area referred to in the embodiment of the present invention refers to the average printing ink amount of the printing area.
For ease of understanding, referring to fig. 3A, the nozzle 130 includes 9 nozzles, which are respectively identified as nozzles No. 1 to 9 in the order from top to bottom in fig. 3A. In single scan printing, the ink discharge amounts of the nozzles No. 1 to No. 9 are Y1, Y2, …, and Y9, respectively.
As described above, nozzles No. 1 to 3 eject ink on the print area 1, nozzles No. 4 to 6 eject ink on the print area 2, and nozzles No. 7 to 9The nozzles eject ink on the print area 3. Thus, the printing ink amount of the printing area 1 is
The printing ink amount of the printing area 2 is
The printing ink amount of the printing area 3 is
In the embodiment of the present invention, if 1 printing region is printed by only 1 nozzle to eject ink, the amount of printing ink in the printing region is equal to the ink discharge amount of the nozzle.
In another embodiment of the present invention, there is provided, inter alia, another method of determining an amount of printing ink in a multiple Pass print scan mode. Referring to fig. 3B, in the multi-Pass scanning printing mode, the heads are stepped by Pass h in a vertically downward direction in fig. 3B at a time, and Pass h represents a step distance. When the 3 rd Pass printing is performed, the printing area 1 includes ink for the 1 st Pass printing, ink for the 2 nd Pass printing, and ink for the 3 rd Pass printing. Thus, the printing ink amount of the printing area 1 is
The printing ink amount of the printing area 2 is
The printing ink amount of the printing area 3 is
In the present embodiment, the print ink amount is an accumulated print ink amount in the print area, and the matching degree between the output power and the print ink amount is increased in the subsequent processing by taking the multi-Pass interpolated ink amount into consideration.
The distance between the light source and the print area refers to a distance between a center position of the light source and a center position of the print area. In another embodiment of the present invention, the distance between the light source and the printing area may also be the shortest distance between the light source and the printing area. In other embodiments of the present invention, the distance between the light source and the printing region may be a distance between any point of the light source and any point of the printing region.
In S20, the distances between the light sources and the print areas are different, and the different distances correspond to different power weights, and the power weights are positive and real numbers. In one embodiment of the invention, the power weight is less than or equal to 1. In a preferred embodiment of the invention, the distance between the light source and the print area is inversely proportional to the power weight, i.e. the larger the distance, the smaller the power weight.
Therefore, the output power of each light source can be determined separately according to the power weight of the light source with respect to each printing area and the amount of printing ink of each printing area. In one embodiment, the output power of any one of the light sources is equal to the sum of the products of the printing ink amounts of i of all the printing areas and the power weights of the light source for the i printing areas. Taking the 3 printing areas shown in the foregoing embodiment as an example, the value range of i is 1 ≦ i ≦ 3, where i is a positive integer. For example, the output power of the light source 1 is equal to the product of the power weight of the light source 1 for the printing area 1 and the amount of printing ink of the printing area 1.
