Description

Technical Field

[0001] The invention relates to the field of inkjet printing control, and in particular to a method and device for multi-pass printing data filling and printing medium control. Background Art

[0002] Inkjet printing is a common printing technology that creates text, images or other content by using the nozzles on an inkjet printer to spray ink in the form of tiny jet particles onto the printing material.

[0003] For small or desktop industrial printing equipment, due to market cost constraints, printers are often equipped with only a single print head. The physical resolution of a single print head often cannot meet the user's requirements for image output quality accuracy in a single pass. It is necessary to use a single print head to use a multi-pass printing method to achieve higher-precision printing output. Due to the fast printing speed of a one-pass spliced ​​multi-nozzle, the ink's drying and curing speed often requires pre-treatment technology or surface modification of the material, and cannot quickly meet the user's printing needs for a variety of materials. Multi-pass printing can effectively solve the problems of output accuracy and material and printing speed adaptation.

[0004] Since multi-pass printing requires the pattern of a unit printing area to be printed through multiple iterations of inkjet printing by the print nozzle and the movement of the printing paper or printing table, interference problems are likely to occur between the passes where adjacent ink droplets are located, resulting in gaps or overlaps between passes in the printing result, affecting the printing quality. Therefore, a print feathering process needs to be added to the multi-pass printing. Print feathering is a method of sampling points or changing the edge arrangement of each pass print nozzle and compensating in subsequent passes. Feathering can weaken the visual defects caused by gaps and overlaps between different printing passes. Existing multi-pass printing methods can only achieve a single function and cannot adapt to the needs of multi-mode or different printing devices. Summary of the invention

[0005] In view of this, the present invention provides a multi-pass printing data filling and printing medium control method, the method comprising:

[0021] When the decimal part of the ratio of the number of data rows MoveCols to the output print resolution multiple Print_multiple meets a preset condition, the determination is stopped and the corresponding number of data rows MoveCols is obtained.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a multi-pass printing data filling and printing medium control method, comprising:

[0040] S1, obtaining the print data of the print file. The print data of the print file can be obtained through the file header of the dot data file produced by the RIP software, such as Figure 2 It is the print data of the print file, including all the print data in the horizontal and vertical directions. The horizontal direction is the X direction and the vertical direction is the Y direction. The print data may be the number of horizontal ink dots, print_X_Dot, and the number of vertical ink dots, Print_Y_Dot.

[0041] S2, calculates printing parameters according to the printing data, the printing parameters include the output printing resolution multiple Print_multiple, the number of data lines read and moved each time MoveCols, the number of print data filling shifts move_times, the number of print head nozzles used UsedNozzles, the number of feathering nozzles EcoNozzles, the starting position of the print data filling array PosCols, and the paper moving distance float step_move_dis for each printing.

[0042] Specifically, the output print resolution multiple Print_multiple refers to the resolution of the print output being a multiple of the original print file data. The number of data rows read and moved each time MoveCols refers to the number of rows read and moved from the print data each time, for example, Figure 2 How many lines of print data can be read each time in the Y direction. If one line can be read each time, the data that can be read is D11-D1m. If two lines can be read each time, the data that can be read is D11-D2m. The number of print data filling shifts move_times refers to the number of times the nozzle data is filled into the print head. The number of print head nozzles used UsedNozzles refers to the number of nozzles required to print the original print file, including feathering nozzles and supplementary feathering nozzles. The number of feathering nozzles EcoNozzles refers to the number of nozzles that need to be feathered in the used nozzles. The starting position of the print data filling array PosCols refers to the starting position of the line print data read each time, which can be Figure 2 The paper moving distance for each print float step_move_dis refers to the distance the paper moves upward after each print.

[0043] S3, create a print buffer data array printdata[Y][X]. The print buffer array printdata[Y][X] refers to caching the print parameters of the original file into a two-dimensional array, where Y represents the number of columns in the array, and X represents the number of rows in the array. Each element in the array represents a print dot, and the array size is printdata[PosCols+MoveCols][print_X_Dot].

[0044] S4, according to the number of data rows MoveCols, and starting from the starting position PosCols of the print data filling array, the current row print data and the corresponding number of horizontal ink dots print_X_Dot in the print data are filled into the Y dimension and X dimension of the print buffer data array printdata[Y][X] respectively. For example, if the number of data rows MoveCols is 1, the print data in the first row is filled into the Y dimension of the print buffer data array printdata[Y][X], and the number of horizontal ink dots print_X_Dot is filled into the X dimension of printdata[Y][X], so that printdata[1]=[MoveCols][print_X_Dot] is obtained; if the number of data rows MoveCols is 2, the print data in the second row is filled into the Y dimension of the print buffer data array printdata[Y][X], and the number of horizontal ink dots print_X_Dot is filled into the X dimension of printdata[Y][X] is obtained, so that printdata[2]=[2MoveCols][print_X_Dot] is obtained, and so on.

[0045] S5, for the row print data of the data bit of the Y dimension in the print buffer data array printdata[Y][X] filled this time, the row print data with a resolution equal to the output print resolution multiple Print_multiple is respectively filled into the nozzle data array Fillrevdata[Y][X] corresponding to the number of used nozzles of the print head UsedNozzles. For example, the data bit 1 of the Y dimension in the print buffer data array printdata[Y][X] is an integer multiple of Print_multiple and is respectively filled into the corresponding used nozzle array, so as to obtain Fillrevdata[{0,1....UsedNozzles}][i]=printdata[Print_multiple*{0,1....UsedNozzles}][i].

[0046] S6, feathering the nozzle data corresponding to the number of feathered nozzles EcoNozzles in the Y dimension of the used nozzle data array Fillrevdata[Y][X] filled this time. Feathering the nozzles in the filling nozzle array, such as feathering the nozzle data with the Y dimension of 0, 1, 2....EcoNozzles in the Fillrevdata[{0, 1....UsedNozzles}][i] array, including feathered nozzles and supplementary feathered nozzles.

[0047] S7, fill the nozzle data of the nozzle data array Fillrevdata[Y][X] completed by this feathering into the corresponding print head nozzle, and control the paper movement according to the paper movement distance float step_move_dis each time to complete the line printing of this time. Fill the feathering nozzle data and the supplementary feathering nozzle data into the corresponding printing nozzle position of the printer, and after the nozzle inkjet is completed, control the paper movement according to the printing paper movement distance to complete the printing of this line.

[0048] S8, move the row print data in the Y dimension in the print buffer data array printdata[Y][X] upward by the corresponding number of data rows MoveCols, fill the print head nozzles in turn according to the number of print data filling shifts move_times to spray ink, and control the movement of paper to complete each row printing. After completing one row printing, jump to the next row in the Y dimension in the print buffer data array printdata[Y][X] to execute the operations of steps S4-S7 until printdata[PosCols]=printdata[PosCols+MoveCols] is reached, that is, fill, feather and print the data of each row until all rows are printed and then end.

[0049] This embodiment determines the basic printing parameters by reading the print data of the print file, and then reads the print parameters in sequence according to the print parameters, and fills the buffer array corresponding to the print nozzle with the print data read each time, and feathers the print nozzles that need to be feathered, so that the corresponding reserved feathering nozzles are filled with the corresponding feathering nozzle data to achieve compensation of printing ink droplets, and the buffer array of the corresponding print nozzles under each printing pass is filled by reading the print data cyclically and shifting iteratively, and the nozzles are controlled to print to the expected position of the paper to achieve image formation by controlling each movement of the printing paper. Therefore, the filling of the corresponding nozzles can be achieved by passing parameters to the control algorithm of the present application method under different feathering nozzle number ranges, different printing passes, and different print nozzle physical resolutions, so that the printing method of the present application is suitable for different printing heads, printing resolutions, and feathering depth settings, while ensuring that the paper feeding distance is consistent each time.

[0050] Furthermore, in addition to the horizontal ink dot number print_X_Dot, the above-mentioned print data also includes: output horizontal resolution Print_Xdpi, output vertical resolution Print_Ydpi, print head nozzle physical resolution PrintHead_res, and the total number of nozzles of each printing channel PrintHead_nozzlesT. The vertical resolution Print_Ydpi is a multiple of the print head nozzle physical resolution PrintHead_res, and the total number of nozzles of each printing channel PrintHead_nozzlesT is the number of nozzles of each color printing channel.

[0051] In one embodiment, step S2 specifically includes:

[0052] S211, calculating the output print resolution multiple Print_multiple according to the output vertical resolution Print_Ydpi and the print head nozzle physical resolution PrintHead_res. The output print resolution multiple Print_multiple is calculated using the following formula:

[0053]

[0054] In one embodiment, step S2 specifically includes:

[0055] S221, calculating the value range of the number of feathering nozzles EcoNozzles according to the total number of nozzles PrintHead_nozzlesT of each group of printing channels.

[0056] S222, calculating the maximum value of the number of data rows MoveCols according to the value range of the number of feathering nozzles EcoNozzles and the total number of nozzles PrintHead_nozzlesT of each group of printing channels.

[0057] S223, starting from the maximum value of the number of data rows MoveCols, the number of data rows is reduced in sequence, and determining whether the decimal part of the ratio of the number of data rows MoveCols to the output print resolution multiple Print_multiple satisfies a preset condition.

[0058] S224, when the decimal part of the ratio of the number of data rows MoveCols to the output print resolution multiple Print_multiple meets the preset condition, the determination is stopped and the corresponding number of data rows MoveCols is obtained.

[0059] Specifically, according to the print data iteration method, the starting position of the data read and filled from the beginning of the first print pass is D[1], and the data position read and filled from the second print pass is D[MoveCols+1]. The data inkjet position after each reading is the position of the adjacent nozzles of the print head. or Therefore, the decimal part of the remainder of MoveCols / Print_multiple needs to be or It can be expressed as the following formula:

[0060]

[0061] First, it is necessary to calibrate the approximate range of the number of feathered nozzles of EcoNozzles, where (the number of feathered nozzles + the number of supplementary feathered nozzles) < the total number of nozzles in each group of print channels PrintHead_nozzlesT, the number of feathered nozzles = the number of supplementary feathered nozzles, and the expected range of the number of feathered nozzles EcoNozzles is obtained by EcoNozzles < (PrintHead_nozzlesT / 2);

[0062] Then, the maximum value of the number of data rows MoveCols is calculated according to the formula MoveCols = PrintHead_nozzlesT-EcoNozzles;

[0063] Finally, start from the maximum value of the number of data rows MoveCols and reduce them in sequence, and determine whether the decimal part of the ratio of the number of data rows MoveCols to the output print resolution multiple Print_multiple satisfies or When the above conditions are met, the calculation stops and the number of data rows MoveCols is obtained.

[0064] In one embodiment, step S2 specifically includes:

[0065] S231, calculating the number of times move_times required for filling and shifting the print data at the output print resolution multiple Print_multiple according to the calculated number of data rows MoveCols.

[0066] Specifically, the number of times move_times (integer) required to fill and shift the print data is calculated using the following formula:

[0067]

[0068] In one embodiment, step S2 specifically includes:

[0069] S241, calculating the number of used nozzles of the print head UsedNozzles according to the calculated number of data rows MoveCols, the number of times move_times required for filling and shifting the print data, and the output print resolution multiple Print_multiple.

[0070] Specifically, the number of used nozzles of the print head is calculated using the following formula:

[0071]

[0072] In one embodiment, step S2 specifically includes:

[0073] S251, calculating the number of feathering nozzles EcoNozzles according to the calculated number of used nozzles of the print head UsedNozzles and the number of data rows MoveCols.

[0074] Specifically, the number of feathering nozzles EcoNozzles is calculated using the following formula:

[0075] EcoNozzles=UsedNozzles-MoveCols

[0076] In one embodiment, step S2 specifically includes:

[0077] S261, calculating the starting position PosCols of the print data filling array according to the calculated number of data rows MoveCols and the print data filling shift times move_times.

[0078] Specifically, the following formula is used to calculate the starting position PosCols of the print data filling array:

[0079] PosCols=(move_times-1)×MoveCols

[0080] In one embodiment, step S2 specifically includes:

[0081] S271, calculate the paper moving distance float step_move_dis for each printing according to the output vertical resolution Print_Ydpi and the calculated number of data rows MoveCols.

[0082] Specifically, the following formula is used to calculate the paper moving distance float step_move_dis each time printing:

[0083]

[0084] For example, if the output vertical resolution is 720dpi, the physical resolution of the print head is 180dpi, the total number of nozzles in each printing channel is 30, and the expected number of feathering nozzles is 11, then the above calculation can be used to obtain

[0085] Print_multiple=720 / 180=4

[0086] MoveCols=19

[0087]

[0088]

[0089] EcoNozzles=UsedNozzles-MoveCols=10

[0090] PosCols=(move_times-1)×MoveCols=95
