Description

Technical Field

[0001] This invention relates to the field of industrial printing technology, and in particular to a method, apparatus, equipment and medium for controlling suction power based on ink properties. Background Technology

[0002] Reciprocating scanning printing technology is a commonly used technology in the inkjet printing field. Reciprocating scanning printing is also known as multi-pass scanning printing. Multi-pass scanning printing means that each unit of the image to be printed must be interpolated multiple times to complete the printing. Each unit is composed of multiple pixels. For example, in 2-pass scanning printing, each unit is composed of 2 pixels, and in 3-pass scanning printing, each unit is composed of 3 pixels. The principle is that the printing carriage moves left and right, so that the print head scans and prints line by line. Then, the image is stitched together by the material feeding to print the image.

[0003] Most existing inkjet printers are equipped with a suction platform to create negative pressure to attract and fix the material, thereby improving print quality and preventing the printing media from bulging and scratching the print head during carriage movement. However, existing suction platforms all use the same suction power. When printing with inks that have different permeability, the different leveling and permeability of the inks result in inconsistent leveling effects, leading to unsatisfactory print quality.

[0035] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, 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. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0037] Example 1

[0038] See Figure 1 The printer includes three printheads, which are used to spray white ink, colored ink, and a third type of nozzle, respectively. Each printing area is completed by three printing passes. For example, in this embodiment, the first printing pass of printing area 1 is completed by printhead 1, the second printing pass is completed by printhead 2, and the third printing pass is completed by printhead 3. Then the printheads leave area 1 and continue to print other areas. At the same time, it can be seen from the covering process that printing area 1 is completed layer by layer. Therefore, it is necessary to adjust the suction power of the area after each layer is completed to ensure that the covering effect is the same each time.

[0039] Please see Figure 2 This invention provides a suction power control method based on ink properties, applied to a printer. The printer includes at least a first printhead, a second printhead, and a suction platform. The first and second printheads are arranged sequentially in the printhead stepping direction. The first printhead is used to spray a first type of ink, and the second printhead is used to spray a second type of ink. The method includes:

[0040] S1: Based on the ink parameters of the first ink and the second ink, obtain the corresponding first preset power and second preset power;

[0041] S2: Divide the printing medium into at least one printing area according to the lengths of the first type of printhead, the second type of printhead, and the image to be printed;

[0042] S3: When inkjet printing the image to be printed, the suction power of the printing area is set to the first preset power when the first type of printhead enters the printing area, and the suction power of the printing area is set to the second preset power when the second type of printhead enters the printing area.

[0043] Specifically, in this embodiment, the printer includes at least a first printhead, a second printhead, and a suction platform. The first printhead is used to spray a first type of ink, and the second printhead is used to spray a second type of ink. The first and second printheads are arranged sequentially in the printhead stepping direction. First, the ink parameters of the first and second types of ink are obtained. Based on the ink parameters, a first preset power and a second preset power are obtained. Then, based on the lengths of the first and second printheads and the image to be printed, the printing medium is divided into at least one printing area. When inkjet printing the image to be printed, the suction power of the printing area is set to the first preset power when the first printhead enters the printing area, and the suction power of the printing area is set to the second preset power when the second printhead enters the printing area. The method of this embodiment sets the suction power of different printing areas according to the properties of different inks, so that each ink can fully penetrate and level, thereby improving the problem that multiple inks using the same suction power result in poor penetration and leveling, ultimately leading to unsatisfactory printing effects.

[0044] In one embodiment, the ink parameters include ink permeability, wherein the ink permeability of the first ink is greater than that of the second ink, and the first preset power is less than the second preset power. When the ink permeability of the first ink is greater than that of the second ink, if the same suction power is used, it cannot be guaranteed that each ink can fully permeate and level. Even if it is possible to ensure that each ink can fully permeate and level when the suction power is high, it will result in energy waste, which does not meet the current requirements for energy conservation and carbon reduction. Setting different suction power according to different ink permeability can ensure that each ink can fully permeate and level, and save energy.

[0045] In one embodiment, the first type of nozzle and the second type of nozzle have the same length, see [reference needed]. Figure 3 The step of dividing the printing medium into at least one printing area based on the lengths of the first type of printhead, the second type of printhead, and the image to be printed includes:

[0046] S21: Determine the number of printing passes based on the image precision of the image to be printed and the nozzle precision of the first type of printhead and the second type of printhead;

[0047] S22: Determine the width of the printing area based on the number of print passes and the length of the first type of printhead;

[0048] S23: Determine the number of printing areas based on the width of the printing area and the image to be printed.

[0049] Specifically, the length of the printhead and the number of print passes are first obtained. In this embodiment, the first and second printheads are used to spray different types of ink. The first and second printheads have the same printhead precision, and the length of the first printhead is equal to the length of the second printhead. When multiple printheads spray the same ink, the printhead length is the length of the multiple printheads spliced ​​together. The number of print passes refers to the number of interpolations required for each unit of the image to be printed to be completed. Each unit consists of multiple pixels. When the number of print passes is 2, each unit consists of 2 pixels. When the number of print passes is 3, each unit consists of 3 pixels. After obtaining the length of the printhead and the number of print passes, the width of the printing area is calculated according to the formula: Printing area width = Printhead length / Number of print passes. After obtaining the width of the printing area, it can be obtained based on the width of the image to be printed and the width of the printing area.

[0050] In one embodiment, the printing area includes at least a first printing area and a second printing area. When inkjet printing the image to be printed is performed, setting the suction power of the printing area to a first preset power when the first printhead enters the printing area, and setting the suction power of the printing area to a second preset power when the second printhead enters the printing area, includes:

[0051] When the first type of nozzle and the second type of nozzle are located in the first printing area and the second printing area respectively, the suction power corresponding to the first printing area is set to the first preset power, and the suction power corresponding to the second printing area is set to the second preset power.

[0052] In one embodiment, the printer further includes a third printhead for ejecting a third type of ink, and the method further includes:

[0053] Based on the ink parameters of the third type of ink, obtain the third preset power;

[0054] When inkjet printing the image to be printed is performed, the suction power of the printing area is set to the third preset power when the third printhead enters the printing area.

[0055] Specifically, the printer also includes a third printhead for ejecting a third type of ink. The printhead precision of the third printhead is the same as that of the first and second printheads, and the length of the third printhead is the same as that of the first and second printheads. First, a third preset power is obtained based on the ink parameters of the third type of ink. When inkjet printing the image to be printed, the suction power of the printing area is set to the third preset power when the third printhead enters the printing area. When printing is in 1-pass mode, see [link to relevant documentation]. Figure 1The first type of printhead first enters area 1 for printing. When it enters area 1, the suction power of area 1 is adjusted from the basic suction power to the first preset power. When the first type of printhead enters area 2 and the second type of printhead enters area 1, the suction power of area 2 is adjusted from the basic suction power to the first preset power and the suction power of area 1 is adjusted from the first preset power to the second preset power. When the first type of printhead enters area 3, the second type of printhead enters area 2 and the third type of printhead enters area 1, the suction power of area 3 is adjusted from the basic suction power to the first preset power, the suction power of area 2 is adjusted from the first preset power to the second preset power, and the suction power of area 1 is adjusted from the second preset power to the third preset power. This process is repeated for each area until printing is complete. In a specific embodiment, the first type of ink is white ink, the second type of ink is colored ink, and the third type is varnish.

[0056] In one embodiment, the ink parameters further include ink surface tension, wherein the ink permeability of the third ink is less than that of the second ink, and the ink surface tension of the third ink is greater than that of the first ink and the second ink.

[0057] In one embodiment, when the number of print passes is less than or equal to the preset number of print passes, the third preset power is greater than or equal to the second preset power.

[0058] In one embodiment, when the number of print passes is greater than the preset number of print passes, the third preset power is less than the second preset power and greater than the first preset power;

[0059] In one specific embodiment, the printing pass number is 4. The penetration rate of the first ink is greater than that of the second ink, which is greater than that of the third nozzle. However, due to the characteristics of the third nozzle, its tension is greater. Therefore, the first preset power is less than the second preset power, and the third preset power is less than the second preset power. During printing, the first nozzle first enters 1 / 4 of region 1 for printing. When the first nozzle enters region 1, the suction power of region 1 is adjusted from the basic suction power to the first preset power. Then, the first nozzle enters 1 / 2, 3 / 4, ... of region 1. During this process, the suction power of region 1 is controlled at the first preset power. When the first ink... When the first nozzle enters 1 / 4 of area 2 and the second nozzle enters 1 / 4 of area 1, adjust the suction power of area 2 from the basic suction power to the first preset power and the suction power of area 1 from power A to the second preset power, and then keep the suction power unchanged. When the first nozzle enters 1 / 4 of area 3 and the third nozzle enters 1 / 4 of area 1, adjust the suction power of area 3 from the basic suction power to the first preset power, the suction power of area 2 from the first preset power to the second preset power, and the suction power of area 1 from the second preset power to the third preset power, and then keep it unchanged, and so on, continuously adjusting the suction power of each area until printing is complete.

[0060] The ink-based suction power control method provided in this invention acquires printing data, determines the ink volume for each pass based on the printing data, and sets the suction power according to the ink volume for each pass, so that the suction power for each pass is different. This avoids problems such as uneven printing caused by the ink having high penetration and large ink droplets in the first print and low penetration and small ink droplets in the later print when the suction power is the same for each pass. By determining the ink volume for each pass based on the printing data and the suction power for each pass based on the ink volume, the ink penetration and ink droplets of each pass are kept as similar as possible, thereby resulting in good printed image quality and uniform color.

[0061] Example 2

[0062] Please see Figure 4 This invention provides a suction power control device based on ink properties, characterized in that the printer includes at least a first type of printhead, a second type of printhead, and a suction platform. The first type of printhead and the second type of printhead are arranged sequentially in the printhead stepping direction. The first type of printhead is used to spray a first type of ink, and the second type of printhead is used to spray a second type of ink. The device includes:

[0063] The power acquisition module is used to acquire the corresponding first preset power and second preset power based on the ink parameters of the first ink and the second ink.

[0064] The printing area division module is used to divide the printing medium into at least one printing area based on the lengths of the first type of printhead, the second type of printhead, and the image to be printed.

[0065] The power setting module is used to set the suction power of the printing area to the first preset power when the first type of printhead enters the printing area, and to set the suction power of the printing area to the second preset power when the second type of printhead enters the printing area, during inkjet printing of the image to be printed.

[0066] The suction power control method, apparatus, and device based on ink properties provided in this invention use different suction power in different printing areas according to the characteristics of different inks, so that each ink can fully penetrate and level.
