[0048] 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.

[0049] 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.

[0050] Example 1

[0051] Please see Figure 1 This invention provides a printing method based on splicing print files, the method comprising:

[0052] S1: Obtain substrate information.

[0053] Specifically, the substrate information includes: substrate size, substrate shape, substrate material, order batch of the substrate, and substrate color. In existing inkjet printing technology, when the material, shape, size, and color of the substrate being printed differ, the same image will produce different printed files.

[0054] S2: Obtain several images to be printed, process the images to be printed according to the substrate information, and generate several first print files.

[0055] Specifically, when the substrate information is different, the first print file generated after processing the same image to be printed according to the substrate information will be different.

[0056] For example, when the same image to be printed needs to be printed on substrates of different sizes, that is, the printing area sizes corresponding to the two substrates are different, the first print file generated by processing the image to be printed will also be different.

[0057] S3: Combine several of the first files to be printed to generate a second print file.

[0058] Specifically, splicing the first printed file includes splicing several first printed files to generate a second printed file, or splicing several first printed files according to preset requirements to generate multiple second printed files, that is, the number of second printed files is greater than or equal to 1 and less than or equal to the number of first printed files.

[0059] By splicing the first print file, the number of print files is reduced, the number of times print files are sent to the printer is reduced, and the number of times the printer needs to be reset after printing a print file is completed is reduced, thus reducing the number of operations of the printing system and improving the printing efficiency of the printer.

[0060] S4: Control the printhead to perform inkjet printing on the substrate according to the second print file.

[0061] The printing method based on print file splicing provided by this invention involves: acquiring substrate information; acquiring several images to be printed; processing the images to be printed according to the substrate information to generate several first print files; splicing the first print files to generate a second print file; and controlling the printhead to perform inkjet printing on the substrate according to the second print file. By processing the images to be printed according to the substrate information corresponding to the substrate to be printed, acquiring first print files, splicing the first print files to generate second print files, and splicing multiple first print files to obtain the second print file, the number of print files can be reduced, the number of times the printer needs to be reset during printing can be reduced, and printing efficiency can be improved.

[0062] In one embodiment, such as Figure 2 As shown, step S2 involves acquiring several images to be printed, processing the images to be printed according to the substrate information, and generating several first print files, including:

[0063] S201: Assign several of the images to be printed to a RIP software;

[0064] S202: The RIP software processes several images to be printed based on the substrate information to generate several first print files.

[0065] Specifically, several images to be printed are acquired and assigned to RIP software for processing. Each image is processed according to the substrate information corresponding to the substrate it needs to be printed on, resulting in a corresponding first print file. When the same image needs to be printed on multiple substrates with different substrate information, the corresponding first print files may be different. The several images to be printed are processed to generate several corresponding first print files.

[0066] In this embodiment of the invention, several first printed documents are spliced ​​together to generate one or more second printed documents. By splicing the printed documents, several first printed documents are combined into one second printed document, reducing the number of printed documents or the number of printed documents received by the printer. Therefore, when inkjet printing is performed on the substrate according to the second printed document, the printing device does not need to reset every time inkjet printing is performed on different substrates, or the number of printer resets is reduced. This enables continuous printing, reduces the printer reset time, and improves printing efficiency.

[0067] In one embodiment, such as Figure 3 As shown, step S2 involves acquiring several images to be printed, processing the images to be printed according to the substrate information, and generating several first print files, including:

[0068] S211: Assign several of the images to be printed to multiple RIP software programs;

[0069] S212: The RIP software processes the image to be printed according to the substrate information to generate several first print files.

[0070] Specifically, several images to be printed are assigned to multiple RIP software programs for image processing to generate several first print files. These first files are then concatenated to generate the second print file. Compared to the previous embodiment, this embodiment improves the generation speed of the first print file by assigning several images to be printed to multiple RIP programs for processing. This solves the problem of slow image import and processing speeds when a large number of images are present, avoiding the issue of slow image import and processing speeds caused by a single RIP software processing the images to generate the first print file. From the perspective of the entire printing process, this increases the generation speed and efficiency of the first print file.

[0071] The first printed file is combined into a second printed file. This can be done by combining several first printed files into one second printed file, or by combining several first printed files separately to generate multiple second printed files. The number of second printed files must be less than the number of first printed files.

[0072] In one embodiment, step S3: concatenating several first documents to be printed to generate a second printable document includes:

[0073] The first print files are grouped together, and the first print files in the same group are spliced ​​together to generate the second print file.

[0074] Specifically, the first printed files are grouped according to the substrate information corresponding to the first printed files. That is, first printed files with the same substrate information are grouped together, and the first printed files within a group are spliced ​​together to generate a second printed file. The number of groups into which the first printed files are divided is the number of groups in the generated second printed files. The number of second printed files is greater than or equal to 1 and less than the number of first printed files.

[0075] This invention employs RIP software to process several images to be printed, generating several first print files. The first print files corresponding to the same substrate information are grouped together, and the first print files within a group are then spliced ​​together to generate a second print file. This embodiment splices the first print files corresponding to the same substrate information based on the similarity between them. For example, images to be printed in the same order may have the same substrate size, thus the image data of the corresponding first print files may also be the same.

[0076] Alternatively, several images to be printed can be distributed to multiple RIP software programs for processing to generate the first print file. The first print files are then grouped according to the substrate information corresponding to each first print file, and the first print files in the same group are spliced ​​together. By using multiple RIP software programs for image processing, the generation speed of the first print file is improved, increasing production efficiency. Grouping the first print files and splicing them together within the same group generates the second print file. Compared to splicing all the first print files into a single second print file, when controlling the printing device to perform inkjet printing using the second print file obtained according to the method of this embodiment, the printing device needs to be reset multiple times to switch the print file from one second print file to the next. However, this embodiment also provides more convenient control over the printing process and the substrate during printing.

[0077] In one embodiment, such as Figure 4 As shown, step S3: concatenating the first document to be printed to generate a second document, includes:

[0078] S31: Obtain the corresponding image parameter information based on the first printed file. The image information includes image size, number of bits, and number of color channels.

[0079] S32: Based on the image parameter information, the different first print files are spliced ​​together to obtain the second print file.

[0080] Specifically, the image size includes image height data and image width data. The image is an image that can be generated by inkjet printing from the first print file. The number of bits indicates whether ink is dispensed or not, and the size of the ink droplets. For example, 1-bit image data includes 0 and 1, where 0 indicates no ink is dispensed at that position, and 1 indicates ink is dispensed at that position. 2-bit image data includes 0, 1, 2, and 3, where 0 indicates no ink is dispensed at that position, 1 indicates a small ink droplet at that position, 2 indicates a medium ink droplet at that position, and 3 indicates a large ink droplet at that position, etc. The color channels generally include four color channels: C, M, Y, and K, as well as some spot color channels. The number of color channels refers to how many colors are used to compose the colors in the first print file. When the first print file is composed of four colors: C, M, Y, and K, the number of color channels is 4. When the first print file is composed of four colors: C, M, Y, and K, and one spot color, the number of color channels is 5.

[0081] In one embodiment, such as Figure 5 As shown, step S32: stitching together different first print files according to the image parameter information to obtain the second print file includes:

[0082] S321: Obtain the original file data of the color channel at the same horizontal position as the printing position of the substrate corresponding to the first print file;

[0083] S322: Generate print file data for the print position by splicing the original file data, and generate a data set based on the print file data, wherein the data set is the second print file.

[0084] In one embodiment, such as Figure 6 As shown, step S3: concatenating several first files to be printed to generate a second print file includes:

[0085] S331: Obtain the print data corresponding to the two adjacent first print files based on the print position;

[0086] S332: Based on the printing position, the printed data is spliced ​​horizontally or vertically.

[0087] Specifically, the first print file consists of file data from several one-pass print areas, such as... Figure 7 As shown, the inkjet scanning coverage area for a one-pass printing zone refers to the area printed by the printhead from left to right once. In multi-pass reciprocating scanning printing, the one-pass printing zone is the area covered by a certain number of nozzles in the printhead once. In one-pass three-scan printing, the one-pass printing zone is the area covered by all the nozzles in the printhead once.

[0088] When splicing two first printed files, the original file data corresponding to a certain pass print area in the first first printed file to be spliced ​​is obtained, and the original file data corresponding to a certain pass print area in the second first printed file that is at the same horizontal position as the certain pass print area in the first first printed file is obtained. The original files of the two second printed data are then spliced ​​together. Figure 8 , Figure 9 As shown, when splicing the first printed file 1 and the first printed file 2, the original file data N1 corresponding to a certain pass printing area n1 and the original file data M1 corresponding to a certain pass printing area m1 at the same level of the corresponding substrate printing area of ​​the two first printed files are spliced ​​to obtain the printed file data A1 at the same level.

[0089] When splicing three of the first print files, the original file data corresponding to a certain pass print area at the same level of the three first print files are spliced ​​together to obtain print file data at the same level position.

[0090] A first print file contains multiple original file data for a certain pass. The original image data at the same horizontal position of each first print file are spliced ​​together. After splicing the original image data at the same horizontal position, the print file data at the corresponding horizontal position is obtained. That is, when two first print files are spliced ​​together, A1 = N1 + M1, A2 = N2 + M2, ..., all print file data A1, A2, ... are combined into a data set T, and the data set T is the second print file.

[0091] The vertical splicing is as follows Figure 10 As shown, Figure 10 M1 and M3, and M2 and M4 are vertically joined. After printing M1 and M2, the printer prints M3 and M4, which are then horizontally joined together.

[0092] Before printing, the second print file is sent to the printer for inkjet printing, enabling the printer to print continuously based on the second print file. This solves the problem that in existing inkjet printing technology, the printer needs to reset after printing one print job, which causes the printer to constantly reset and print when printing multiple print jobs, affecting printing speed and improving printing efficiency.

[0093] After obtaining the second print file, the print head is controlled to perform inkjet printing on the substrate corresponding to the first print file that makes up the second print file, that is, the substrate is positioned according to the splicing order of the first print file, and inkjet printing is performed according to the second print file to obtain the printed product.

[0094] The printing method based on print file splicing provided by this invention involves: acquiring substrate information; acquiring several images to be printed; processing the images to be printed according to the substrate information to generate several first print files; splicing the first print files to generate a second print file; and controlling the printhead to perform inkjet printing on the substrate according to the second print file. By processing the images to be printed according to the substrate information corresponding to the substrate to be printed, acquiring first print files, splicing the first print files to generate second print files, and splicing multiple first print files to obtain the second print file, the number of print files can be reduced, the number of times the printer needs to be reset during printing can be reduced, and printing efficiency can be improved.
