Background technique

With the increasing improvement of spiritual and cultural life, people's appreciation of art and the requirements for quality are correspondingly higher and higher, including the requirements for printed products. In order to improve the quality of the printed product and improve the gloss of the printed product, a layer of varnish is generally sprayed on the pattern forming ink of the printed product, and a layer of varnish is covered on the pattern forming ink of the printed product.

The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objects, technical solutions and advantages of the present invention more clear, the present 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 only configured to explain the present invention, and are not configured to limit the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the invention.

It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any relationship between these entities or operations. any such actual relationship or sequence exists. Moreover, the terms "comprising", "comprising" or any other variation thereof are intended to encompass a non-exclusive inclusion such that a process, method, article or device that includes a list of elements includes not only those elements, but also includes not explicitly listed or other elements inherent to such a process, method, article or apparatus. Without further limitation, an element defined by the phrase "comprises" does not preclude the presence of additional identical elements in a process, method, article, or device that includes the element.

Referring to FIG. 2 , an embodiment of the present invention provides an ink curing method. The method dynamically adjusts the power of the first light source and the second light source in real time according to the acquired printing times, so that different color inks sprayed on the printing medium can be timely It is thoroughly cured to ensure that the surface of the printed product is flat and there will be no yin and yang colors. At the same time, the transparent ink sprayed on the ink for pattern formation is completely cured, so that the entire product surface is smoother, the color is more saturated, and the image is more delicate and difficult. Discoloration, scratches. The method specifically includes the following steps:

S1. Obtain the number of times of printing covering the designated area of the print medium when jetting ink, the ink includes pattern-forming ink and transparent ink, and the same number of times of printing covering the designated area of the print medium when the pattern-forming ink and the transparent ink are ejected.

Specifically, there are many ways of inkjet printing. Different printing methods cover the designated area of the printing medium with different printing times. At present, inkjet printing methods mainly include reciprocating scanning printing, one-time scanning printing, and multi-nozzle side-by-side scanning printing. Wait. Reciprocating scanning printing is also called multi-pass scanning printing. Multi-pass scanning printing means that each area of the pattern to be printed needs to be interpolated multiple times to complete the printing. For example, 2-pass scanning printing covers the specified area of the printing medium. The number of prints is 2, and 3-pass scan printing covers the specified area of the print medium. The number of times of printing is 3; one-time scan printing is also called single-pass scan printing. Single-pass scan printing means that each area of the medium to be printed only needs The printing can be completed in one scan, that is, the number of times of printing covering the designated area of the printing medium is 1; multi-nozzle side-by-side scanning printing is also called onepass scanning printing. The number of prints for the specified area of the media is also 1. In multi-pass scanning printing, the curing time and coverage level of the pattern forming ink or transparent ink for each pass are different, and the curing time of the pattern forming ink or transparent ink for each pass is based on comprehensive consideration of pattern formation. It is set based on the properties of ink and transparent ink. For example, the curing time of ink with lower hardness is shorter than that of ink with higher hardness. Specifically for 2 passes, the curing time of each pass is the same. The transparent ink printed in the first pass has a relatively longer light exposure time because it is printed first, and is at the bottom layer, while the transparent ink printed in the second pass has a relatively long light exposure time. It is relatively short and is on the top layer. If constant power irradiation is used, the curing effect of the transparent ink printed by the first pass and the second pass will be different, which will make the surface of the printed product uneven and the illumination is not enough.

Preferably, the pattern forming ink includes: cyan ink (Cyan, C), magenta ink (Magenta, M), yellow ink (Yellow, Y), black ink (Black, K), white ink (White, W) ) one or more of. Among them, when there is white ink, if the white ink is used as the substrate layer, the white ink is cured first, and then the inks of other colors are cured; if the white ink is not used as the substrate layer, the white ink and other inks are cured together. Wherein, the transparent ink is liquid varnish.

S2. Determine the power variation rule of the first light source that irradiates the ink for pattern formation according to the number of times of printing, and determine the first light source when there are at least two printing times covering the designated area of the printing medium according to the power variation rule of the first light source. The power of the light source is different;

Specifically, the changing trend of the power of the first light source irradiating the pattern-forming ink is determined according to the number of times of printing. The power of the light source is divided into 4 gears. When irradiating the designated area of the print medium, the power of the first light source is gear 1 when the first light source scans along the main scanning direction for the first time, and when the second scan is performed. The power of the first light source is gear 2, the power of the first light source is gear 3 during the third scan, and the power of the first light source is gear 4 when the fourth scan is performed. In the example, the change of power level is gear 1 < gear 2 < gear 3 < gear 4. Please refer to Figure 3. Each pass prints four colors of ink. The four colors of ink are cyan ink, magenta ink, yellow ink, and black ink. The light source with power gradient is used for curing and irradiation so that each color is irradiated. The ink is not cured at one time, but can be cured and formed through multiple irradiations, which ensures that the complete curing time of each color in the designated area is the same, thus ensuring the mutual fusion of various colors. Printing is prone to yin and yang issues. In another embodiment, the change of the power level is as follows: gear 1 = gear 2 < gear 3 equal to gear 4, and the change of the power of the first light source is based on the formation of different printing media or printing patterns. The ink properties are set, because different printing media have different absorption of pattern-forming inks, and different pattern-forming inks and pattern-forming inks have different adhesion and permeability, and can be adjusted manually or automatically according to different printing modes or printing requirements. The power change rule of the light source can better solidify the ink for pattern formation to make the printed product flat and uniform in color, and the first light source is always turned on during the entire printing process. The first light source may be a UV-LED lamp or a UV mercury lamp, and the specific type of the first light source is not limited herein.

Preferably, the first light source includes at least two wavelengths of LED lamp beads. In this embodiment, the first light source is composed of several lamp beads, the lamp beads are divided into several parts, each part of the lamp bead corresponds to a wavelength, and a wavelength corresponds to a color, as in this embodiment If the lamp bead is divided into 3 parts, the first light source has 3 wavelengths. The 3 wavelengths are the wavelengths that are beneficial to the absorption of cyan ink, the wavelengths that are beneficial to the absorption of magenta ink, and the wavelengths that are beneficial to the absorption of yellow ink. , Magenta, and yellow are the basic colors of color inkjet printing, and cyan, magenta, and yellow are also the three primary colors of art. Other colors can be obtained indirectly by mixing the three colors. The color can be well cured, which ensures the uniform color and smooth surface of the entire printed product.

In another embodiment, there are three first light sources, the three first light sources are arranged in parallel, the wavelengths of each of the light sources are different, and the wavelengths of the three light sources are respectively beneficial to the absorption of the cyan ink The wavelength that is favorable for the absorption of magenta ink and the wavelength that is favorable for the absorption of yellow ink can ensure the uniform color and smooth surface of the entire printed product.

S3. Obtain the relative positional relationship between the print medium and the nozzle, determine the power variation rule of the second light source irradiating the transparent ink according to the relative positional relationship and the number of times of printing, and determine the coverage by the power variation rule of the second light source The power of the second light source is different when there are at least two prints in the designated area of the print medium;

Specifically, in this embodiment, the relative positional relationship is used to determine whether to turn off and on the second light source irradiating the transparent ink, and the number of times of printing is used to determine the amount of time the second light source irradiates the transparent ink. power size. The change of the power of the second light source is set according to different printing media or printing color inks, because different printing media have different absorption of transparent ink, and different pattern forming inks have different adhesion and permeability between transparent ink and transparent ink. , according to different printing modes or printing requirements, manually or automatically adjust the power change law of the light source, which can better cure the transparent ink to make the printed product smooth and glossy; the closing and opening rules of the second light source are: curing The second light source is turned off when the transparent ink in the first area of the adjacent area of the printing medium is finished, and the second light source is turned on when the second area of the adjacent area of the printing medium starts to be cured. Referring to FIG. 4 , in this embodiment, when the first area A of the adjacent area of the printing medium completely enters the irradiation area of the second light source 60 , the second light source 60 is turned on for the first area A. When the second area B completely enters the irradiation area of the second light source 40, the second light source 60 is turned on for the second area. The transparent ink of B is cured by light, and the second light source 60 is turned off after curing is completed. Wherein, the closing and opening of the second light source is set according to the relative movement distance between the printing medium and the nozzle, that is, the Y-axis movement distance of the inkjet printer is set, and the printing is determined by obtaining the Y-axis movement distance. Whether the medium completely enters the irradiation area of the second light source 60 . In the flatbed printer, the print head moves forward for a certain distance under the drive of the Y-axis motor every time the print head scans in the main scanning direction. When the print cart moves for a certain distance under the drive of the Y-axis motor, the printing medium is covered with transparent ink. When entering the irradiation area of the second light source, the second light source is turned on, and then the printing carriage continues to move under the drive of the Y-axis motor. When the printing medium covered with transparent ink leaves the irradiation area of the light source, the second light source The light source is off. In the web printer, the printing medium is moved forward under the driving of the Y-axis motor, and the control of the other second light sources is the same as that of the flatbed printer, and will not be repeated here. Generally, the time interval between turning off and turning on the second light source is 3 to 5 seconds, wherein the second light source can be a UV mercury lamp or a UV-LED lamp, and the specific type of the second light source is not limited here. . The wavelength of the second light source is set according to the properties of the selected transparent ink, and the transparent inks with different properties have different absorption wavelengths.

Referring to FIG. 5, in this embodiment, the step S4 specifically includes the following steps:

S411. Input the power variation rule of the first light source into the main control board of the inkjet printer, and the main control board generates a first initial control signal for controlling the first light source to emit light according to the power variation rule of the first light source ;

The number of times of printing that covers the designated area of the printing medium when the ink is used and the transparent ink is printed, and then the first initial control signal for controlling the light emission of the first light source and the second initial control signal for controlling the second light source are generated according to the printing times. The first initial control signal and the second initial control signal are input to the power adjustment circuit to generate a first control signal for controlling the first light source and a second control signal for controlling the second light source, and the first control signal is input to the first light source to control the second light source. A light source irradiates the pattern forming ink for curing, and then a second control signal is input to the second light source to control the second light source to irradiate the transparent ink printed on the pattern forming ink for curing. Wherein, the second control signal may be a pulse signal or a level signal, which is not specifically limited herein.

Wherein, the printing medium parameters include: printing medium humidity and ink permeability of the printing medium.

Preferably, the power of the light source output by the power adjustment circuit is obtained through frequency conversion power modulation technology (ie pulse frequency modulation technology), and the pulse frequency modulation technology changes the load impedance characteristics by adjusting the frequency of the output voltage of the power supply, that is, changing the relationship between the output voltage and the current of the power supply The phase difference is used to adjust the power output. Different voltage output frequencies correspond to different load impedance characteristics. In this embodiment, the load impedance is the resistance value of the curing lamp, and the light source is a UV-LED lamp. When the frequency of the output voltage of the power supply is equal to or close to the natural frequency of the load, the output power of the power supply reaches the maximum value; when the frequency of the output voltage of the power supply is less than When it is greater than the load natural frequency, the output power of the power supply becomes smaller and the power regulation can be realized by adjusting the working frequency of the power supply. The steady-state control method of the circuit is to adjust the lamp power by changing the frequency. The load equivalent circuit is composed of the load resistance R, the inductance L and the capacitor T in series to form an AC square wave voltage with the bus voltage of the size U. When the load equivalent parameters R, L and T are constant, the load lamp power P can be obtained by using the fundamental wave equivalent principle:
