Description

Ink curing method, device, equipment, printing control system and medium for pattern formation

technical field

The present invention relates to the technical field of inkjet printing, and in particular, to a method, device, equipment, printing control system and medium for curing ink for pattern formation.

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 and printing speed of printed products, more high-resolution inkjet printers are used for product printing. Printers have three or four print heads to print yellow, magenta, cyan, and black; some share one print head and print in four colors. In order to increase the printing speed, the pattern forming ink needs to be dried, so that the product can be packaged and sold after printing.

The ink for pattern formation is a multi-color system. The reflection, transmission and absorption of UV light by various color inks are very different, which affects the absorption of UV light by the photoinitiator, resulting in greatly different curing speed and effect. Experiments show that various color inks have different absorption rates for UV light. The smaller the pigment absorption rate, the higher the light transmittance, and the faster the curing speed of the coating. Generally, the absorbance of ultraviolet light is black, purple, blue, cyan, green, yellow and red in descending order. However, the light source currently used in inkjet is mainly a constant power light source, as shown in Figure 1, the constant power light source makes the wavelength of light generated single, which will lead to uneven curing of the ink coating for pattern formation, and ultimately lead to the formation of ink on the surface of the product. Incomplete curing makes the product prone to uneven chromaticity, that is, yin and yang colors.

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 a method for curing ink for pattern formation. The method obtains the number of times of printing that covers a designated area of the printing medium when the ink for pattern formation is ejected; The power variation rule of the light source of the ink for pattern formation, and a control signal for controlling the light emission of the light source is obtained according to the power variation rule; according to the control signal, the light source is controlled to affect the pattern after printing the ink for pattern formation. The forming ink is photocured. The present invention dynamically adjusts the power of the light source in real time according to the number of printings, so that the inks of different colors sprayed on the printing medium can be solidified in time and completely, ensuring that the surface of the printed product is flat and no yin and yang colors appear.

The method specifically includes the following steps:

S1. Obtain the number of times of printing that covers the designated area of the printing medium when the ink for forming the pattern is sprayed;

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 prints is 3; one-time scan printing is also called single-pass scan printing. Single-pass scan printing means that each area of the pattern to be printed only needs to be 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 of the pattern-forming ink for each pass and the layers covered by the pattern-forming ink are different, and the curing time of the pattern-forming ink for each pass is based on the properties of the pattern-forming ink. For example, the curing time of the pattern-forming ink with lower hardness is shorter than that of the pattern-forming ink with higher hardness. Specifically for 2 passes, the curing time of each pass is the same, then the pattern-forming ink printed in the first pass has a relatively long exposure time because it is printed first, and is at the bottom layer, while the pattern-forming ink printed in the second pass is formed. The time of illumination with ink is relatively short, and it is on the top layer. If constant power illumination is used, the curing effect of the ink used to form the printing pattern of the first pass and the second pass will be different, which will make the surface of the printed product uneven and the illumination intensity. 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, K) ) 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.

S2. Determine the power variation rule of the light source according to the number of times of printing, and determine, according to the power variation rule, that the power of the light source is different during at least two printings in the number of times of printing covering the designated area of the print medium;

Specifically, the changing trend of the power of the light source irradiating the ink for pattern formation is determined according to the number of prints. If the number of times of printing is 4 times and 4-pass printing, the power of the light source irradiating the ink for pattern formation is divided into 4 gears, when irradiating the designated area of the print medium, the power of the light source is gear 1 when the light source scans the main scanning direction for the first time, and the power of the light source is gear 2 when scanning the second time. , the power of the light source is gear 3 when scanning for the third time, and the power of the light source is gear 4 when scanning the fourth time, then in this embodiment, the change in power 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 (Cyan, C), magenta ink (Magenta, M), yellow ink (Yellow, Y), Black ink (Black, K) is cured and irradiated with a power gradient light source, so that the ink of each color is not cured at one time, but can be cured and formed through multiple irradiations, which ensures the complete curing time of each color in the designated area. All are the same, thus ensuring the uniformity of the mutual fusion of various colors, and solving the problem of yin and yang colors that are prone to occur in color printing. In another embodiment, the change in the magnitude of the power is as follows: gear 1 = gear 2 < gear 3 equal to gear 4 . Wherein, the size of the light source power is set according to different printing materials or the properties of the ink for forming the printing pattern, because different printing media absorb the ink for forming the pattern differently, the difference between the ink for forming the pattern and the ink for forming the pattern is different. The adhesion and permeability are different. According to different printing modes or printing requirements, the power change law of the light source can be adjusted manually or automatically, and the ink for pattern formation can be better cured to make the printed product flat and uniform in color. The light source may be a UV-LED lamp or a UV mercury lamp, and the specific type of the light source is not limited herein.

Preferably, the light source includes at least two wavelengths of LED lamp beads. In this embodiment, the 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. For example, in this embodiment, The lamp beads are divided into 3 parts, and the light source corresponds to 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. Yellow is the basic color 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. Therefore, setting the wavelengths that are conducive to the absorption of the three basic color inks enables various colors to be printed. Good curing ensures uniform color and smooth surface of the entire printed product.

In another embodiment, there are three light sources, the three light sources are arranged in parallel, the wavelengths of each light source are different, and the wavelengths of the three light sources are respectively the wavelengths that are favorable for the absorption of cyan ink and the wavelengths that are favorable for the absorption of cyan ink. The wavelengths absorbed by the magenta ink, the wavelengths favored by the yellow ink.

S3. Obtain a control signal for controlling the light source to emit light according to the power variation law;

Referring to FIG. 4, in this embodiment, the step S3 specifically includes the following steps:

S312. Input the initial control signal into the power adjustment circuit of the light source to obtain the control signal.

The number of times of printing that covers the designated area of the printing medium when using ink, and then the initial control signal for controlling the light source to emit light is generated according to the number of printings, and finally the initial control signal is input to the power adjustment circuit to generate the control signal for controlling the light source, and the The control signal is input to the light source to control the light source to irradiate the ink for pattern formation to cure. Wherein, the light source can be a UV mercury lamp or a UV-LED lamp, the specific type of the source of the light source is not limited here, and the control signal can be a pulse signal or a level signal, which is not described here.

Wherein, the printing medium parameters include: printing medium humidity, ink permeability for pattern formation of the printing medium.

Preferably, the power of the light source output by the power adjustment circuit is obtained by frequency conversion power modulation technology (ie, pulse frequency modulation technology), and the pulse frequency modulation technology changes the load impedance characteristic by adjusting the frequency of the output voltage of the power supply, that is, changing the output voltage of the power supply and the frequency of the power supply. The phase difference between the currents 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 light source, 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 or When it is greater than the natural frequency of the load, the output power of the power supply becomes smaller and power regulation can be realized by adjusting the operating 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 consists of the load resistance R, the inductance L and the capacitor C connected in series to form an AC square wave voltage whose bus voltage is U. When the load equivalent parameters R, L and C are constant, the load lamp power P can be obtained by using the fundamental wave equivalent principle:
