Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a printing method, system and equipment. Background Art

[0002] With the rapid development of printing technology, inkjet printing has been widely penetrated into many fields. Whether it is the precision pattern printing in industrial manufacturing or the delicate painting output in artistic creation, strict requirements are placed on the printing effect. Printing accuracy and printing speed have become key indicators for measuring the performance of printing equipment.

[0003] However, existing printing equipment struggles to achieve a balance between printing accuracy and speed in practical applications. On the one hand, to achieve higher printing precision, printing equipment must process massive amounts of image detail data. For example, when printing high-resolution photos, to clearly render every color transition and texture detail, the equipment must process the high-resolution image pixel by pixel. This exponentially increases the amount of data processing, significantly increasing printing time and severely reducing printing speed.

[0004] On the other hand, simply increasing printing speed often involves simplifying the image data processing, such as reducing resolution and reducing the number of inkjet prints. While this can speed up the printing process, it can also significantly reduce printing accuracy, resulting in blurred images and loss of detail. Summary of the Invention

[0033] Furthermore, the terms “first,” “second,” “third,” etc., are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0034] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which the various embodiments of the present application belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meaning as in the context of the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present application.

[0035] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0036] Example 1

[0037] refer to Figure 1 The embodiment of the present application provides a printing method, which is applied to a control device of a printing system, wherein the printing system further includes: an image generating device and a printing device; the method includes:

[0038] Controlling the image generation device to combine and form an image to be printed that matches the target print image based on the imported print images and the corresponding print position of each print image on the print medium;

[0039] The image generating device increases the resolution of each printed image by a set multiple when forming the images to be printed, so that the resolution of each printed image is increased to the first resolution; wherein the set multiple depends on the position accuracy of the corresponding printed image and the printing process;

[0040] A printing device, obtaining a first resolution and adjusting the first resolution of each printed image based on printing parameters of a print head of the printing device so that the first resolution is adjusted to a second resolution; wherein the printing parameters include a printing rate and an inkjet frequency of the print head;

[0041] Control each print head to print according to the corresponding second resolution.

[0042] Step S10: Based on the imported printing images and the corresponding printing position of each printing image on the printing medium, the image generating device is controlled to combine and form an image to be printed that matches the target printing image.

[0043] The control device receives information about the images to be printed and the specific print locations of each image on the print medium (e.g., paper, fabric, etc.). Following the control device's instructions, the image generation device combines the individual images according to the specified print locations, thereby forming a print image that meets the target print image requirements.

[0044] Step S20: When the image generating device combines to form the image to be printed, it increases the resolution of each printed image by a set multiple so that the resolution of each printed image is increased to the first resolution; wherein the set multiple depends on the position accuracy of the corresponding printed image and the printing process.

[0045] Increasing resolution during the image generation phase allows images to contain greater detail and more precise pixel information. Because print position accuracy is closely related to the pixel accuracy of the image, higher resolution allows the position of each element in the image to be more accurately mapped to the print medium. When converting the image into print data, fractional pixels are processed more precisely, reducing print position inaccuracies caused by pixel position deviations and thus improving print position accuracy. For high-precision pattern printing, high-resolution images ensure sharper details such as pattern edges and lines. During the printing process, the ink jetting position can be more accurately controlled, ensuring that the printed pattern better meets design requirements.

[0046] Step S30: The printing device obtains the first resolution and adjusts the first resolution of each printed image in combination with the printing parameters of the print head of the printing device so that the first resolution is adjusted to the second resolution; wherein the printing parameters include the printing rate and inkjet frequency of the print head.

[0047] While increasing resolution can improve printing accuracy, excessively high resolutions significantly increase the amount of print data. Printing directly at high resolutions may exceed the processing capabilities of the printer, resulting in slower printing or even failure. The print module decomposes the high-resolution image based on the current resolution, the system's configured maximum print rate, and the nozzle's inkjet frequency, either reducing the resolution or performing multiple prints at X sub-resolutions. This breaks down the print task into multiple, relatively simple sub-tasks while maintaining print accuracy, enabling the printer to process data more efficiently and improving overall printing efficiency.

[0048] Step S40: Control each print head to print according to the corresponding second resolution.

[0049] The print head prints according to the adjusted second resolution, which can ensure printing accuracy and printing speed at the same time.

[0050] In some embodiments, when adjusting the first resolution of each printed image, the adjustment is made along a first direction and a second direction corresponding to the printed image; wherein the first direction is perpendicular to the second direction, such as the first direction is the X direction and the second direction is the Y direction.

[0051] After receiving the image to be printed, the printing device decomposes the image resolution based on the current resolution, the system's configured maximum print rate, and the inkjet frequency of the printheads, and then prints the image in multiple passes. During the printing process, X and Y coordinates are used to determine the specific location of the printed content on the print medium. This processing method can be applied in the X direction, performing resolution decomposition and multiple passes along the horizontal direction of the print medium; it can also be applied in the Y direction, performing the same operation along the vertical direction of the print medium. This method improves print position accuracy in both horizontal and vertical directions. For example, when printing a high-precision pattern, the pattern's rich details may necessitate increased resolution in the X direction and multiple passes to ensure horizontal position accuracy and detail. In the Y direction, if the pattern contains fine vertical lines or tiny elements, this method can also be used to perform resolution processing and multiple passes in the Y direction to ensure vertical printing quality and position accuracy.

[0052] In some embodiments, a printing device obtains a first resolution and adjusts the first resolution of each printed image based on printing parameters of a print head of the printing device to adjust the first resolution to a second resolution, including:

[0053] The printing device selects a first adjustment mode or a second adjustment mode according to different printing parameters to adjust the first resolution to the second resolution; wherein the first adjustment mode and the second adjustment mode respectively match different printing parameters.

[0054] The printing device obtains the image's first resolution and, based on the various printing parameters of its printheads, adjusts the first resolution of each printed image, ultimately converting it to a more suitable second resolution for printing. These printing parameters may include the printhead's inkjet frequency, droplet size, print speed, and number of printheads. The printing device determines which adjustment mode to use based on the different printing parameters, optimizing the printed image's resolution for different printing needs and conditions.

[0055] In some embodiments, when the first adjustment mode is selected, the printing device obtains the second resolution of each printed image, and reduces the second resolution to a third resolution in combination with the maximum printing rate and inkjet frequency of the corresponding print head; wherein the third resolution is between the first resolution and the second resolution.

[0056] After receiving the high-resolution image to be printed from the image generation module, the print module adjusts the image resolution based on factors such as the current resolution, the system's configured maximum print rate, and the inkjet frequency of the printhead. Reducing the resolution reduces the number of pixels per unit area of ​​the image. For example, an image originally at 600 dpi (dots per inch) might be reduced to 300 dpi. This approach matches the printer's performance, reduces data processing, and improves printing efficiency. At the same time, the reduced resolution remains higher than the original resolution, ensuring a certain level of printing accuracy.

[0057] In some embodiments, when the second adjustment mode is selected, the printing device obtains the second resolution of each printed image, and prints the printed image in batches in combination with the maximum printing rate and inkjet frequency of the print head, that is, the resolution is subdivided; wherein the number of times of printing is equal to the set multiple.

[0058] Increasing the resolution significantly increases the amount of print data. Printing directly at high resolution may exceed the processing capabilities of the printer, resulting in slower printing speeds or even failure. Subdividing the resolution divides a high-resolution image into multiple prints, breaking down complex print tasks into simpler subtasks. This allows the printer to process data more efficiently, improving overall printing efficiency.

[0059] The image generation module increases the image resolution by a factor of X based on demand. Upon receiving the high-resolution image, the printing module processes the increased resolution based on factors such as the current resolution, the system's configured maximum print rate, and the inkjet frequency of the printheads. It can break up the high-resolution image horizontally (in the X direction) or vertically (in the Y direction), splitting it into multiple prints. For example, an image originally at 100 dpi (dots per inch) increased to 500 dpi might be split into five prints based on the resolution breakdown method, with each print processing only a portion of the resolution information, for example, processing the equivalent of 100 dpi of image data per print.

[0060] Subdividing the resolution can break down the printing task of high-resolution images into smaller pieces, reducing the amount of data printed each time. This not only takes advantage of the precision brought by high resolution, but also avoids performance degradation of the device due to excessive data volume, thus balancing printing accuracy and efficiency.

[0061] Example 2

[0062] The embodiment of the present application provides a printing system, comprising: an image generating device, a printing device, and a control device, wherein the image generating device is communicatively connected to the printing device, and the control device is communicatively connected to the image generating device and the printing device respectively;

[0063] The image generating device is used to form an image to be printed that matches the target printing picture based on a plurality of imported printing images and the corresponding printing position of each printing image on the printing medium.

[0064] The control device receives information about the images to be printed and the specific print locations of each image on the print medium (e.g., paper, fabric, etc.). Following the control device's instructions, the image generation device combines the individual images according to the specified print locations, thereby forming a print image that meets the target print image requirements.

[0065] When combining to form the image to be printed, the image generating device increases the resolution of each printed image by a set multiple so that the resolution of each printed image is increased to the first resolution; wherein the set multiple depends on the position accuracy of the corresponding printed image and the printing process.

[0066] Increasing resolution during the image generation phase allows images to contain greater detail and more precise pixel information. Because print position accuracy is closely related to the pixel accuracy of the image, higher resolution allows the position of each element in the image to be more accurately mapped to the print medium. When converting the image into print data, fractional pixels are processed more precisely, reducing print position inaccuracies caused by pixel position deviations and thus improving print position accuracy.

[0067] A printing device is used to obtain a first resolution and adjust the first resolution of each printed image in combination with printing parameters of a print head of the printing device so that the first resolution is adjusted to a second resolution; wherein the printing parameters include a printing rate and an inkjet frequency of the print head.

[0068] While increasing resolution can improve printing accuracy, excessively high resolutions significantly increase the amount of print data. Printing directly at high resolutions may exceed the processing capabilities of the printer, resulting in slower printing or even failure.

[0069] The control device is used to control each print head to print according to the corresponding second resolution.

[0070] The print head prints according to the adjusted second resolution, which can ensure printing accuracy and printing speed at the same time.

[0071] In some embodiments, a printing device is configured to select a first adjustment mode or a second adjustment mode according to different printing parameters to adjust a first resolution to a second resolution; wherein the first adjustment mode and the second adjustment mode respectively match different printing parameters.

[0072] The printing device obtains the image's first resolution and, based on the various printing parameters of its printheads, adjusts the first resolution of each printed image, ultimately converting it to a more suitable second resolution for printing. These printing parameters may include the printhead's inkjet frequency, droplet size, print speed, and number of printheads. The printing device determines which adjustment mode to use based on the different printing parameters, optimizing the printed image's resolution for different printing needs and conditions.

[0073] In some embodiments, the first adjustment mode is: the printing device obtains the second resolution of each printed image, and reduces the second resolution to a third resolution in combination with the maximum printing rate and inkjet frequency of the corresponding print head; wherein the third resolution is between the first resolution and the second resolution.

[0074] After receiving the high-resolution image to be printed from the image generation module, the print module adjusts the image resolution based on factors such as the current resolution, the system's configured maximum print rate, and the inkjet frequency of the printhead. Reducing the resolution reduces the number of pixels per unit area of ​​the image. For example, an image originally at 600 dpi (dots per inch) might be reduced to 300 dpi. This approach matches the printer's performance, reduces data processing, and improves printing efficiency. At the same time, the reduced resolution remains higher than the original resolution, ensuring a certain level of printing accuracy.

[0075] In some embodiments, the second adjustment mode is: the printing device obtains the second resolution of each printed image, and prints the printed image in batches in combination with the maximum printing rate and inkjet frequency of the print head; wherein the number of batch printings is equal to the set multiple.

[0076] Increasing the resolution significantly increases the amount of print data. Printing directly at high resolution may exceed the processing capabilities of the printer, resulting in slower printing speeds or even failure. Subdividing the resolution divides a high-resolution image into multiple prints, breaking down complex print tasks into simpler subtasks.

[0077] The image generation module increases the image resolution by a factor of X based on demand.
