Fig. 1 is a connection diagram of hardware modules used in a practical application of the print data processing method based on multiple nozzles according to the present invention.

In practice, the present invention is intended to print a red stamp, a blue stamp and a base image on a printing medium such as paper at the same time using a head. The base image includes writing or pattern on the paper surface.

Before printing begins, 3 threads are created by the creation module. Thread 1 connects gradually first processing module and the mainboard of handling base map data, and thread 2 connects gradually second processing module and the mainboard of handling red chapter data, and thread 3 connects gradually third processing module and the mainboard of handling blue chapter data.

The first processing module processes image dot matrix data for the base map acquired by scanning the base map, the second processing module processes image dot matrix data for forming a red seal acquired by scanning a red seal, and the third processing module processes image dot matrix data for forming a blue seal acquired by scanning a blue seal.

The main board obtains image dot matrix data for forming a base image from the first processing module, obtains image dot matrix data for forming a red seal from the second processing module, and obtains image dot matrix data for forming a blue seal from the third processing module.

The various nozzles, upon receiving the data, eject ink under the control of the data.

The bottom nozzles include the black nozzle 003 in fig. 3, and the black head 003 is for ejecting black ink. The red chapter nozzle includes a red ink nozzle 001 in fig. 3, and the red ink nozzle 001 is used to eject red ink. The blue ink nozzle 002 includes the blue ink nozzle 002 in fig. 3, and the blue ink nozzle 002 is used for nozzle of blue ink.

An embodiment of the present invention provides a print data processing method based on multiple nozzles, as shown in fig. 2, the method including the following steps S1-S3.

Step S1: and acquiring image dot matrix data corresponding to each of the nozzles in the plurality of nozzles.

In ink jet printing, only one type of head is typically provided on an ink jet printer. When utilizing ink jet printer to print the pattern of multiple different colours on the print media, ink jet printer often can print a colour pattern earlier, then changes printing ink, prints the pattern of another kind of colour again, and ink jet printer changes printing ink and needs the certain time, and this can cause the pattern to print for a long time, ink jet printer's printing efficiency low.

By arranging a plurality of nozzles on the ink-jet printer and respectively printing the patterns with different colors on the printing medium by utilizing various nozzles, the nozzles for printing the patterns with different colors can finish ink preparation and cache of required data for printing before the start of ink-jet printing, and various nozzles can be utilized to print at any time in the printing process, thereby improving the printing efficiency of the ink-jet printer.

In order to save the printing time, the image dot matrix data corresponding to each of the multiple nozzles needs to be acquired before each inkjet printing. The image lattice data corresponding to each kind of nozzle is composed of a plurality of data distributed in an array, and the array distribution mode of the plurality of data corresponds to the arrangement mode of the spray head. The image dot matrix data corresponding to each type of nozzle may be used to control the ejection state of each of the nozzles.

In one embodiment, the nozzle comprises a plurality of said nozzles for any of a plurality of nozzles. Step S1 includes: and setting the printing parameters of any one of the nozzles in the plurality of nozzles, wherein the printing parameters of each nozzle in the plurality of nozzles form image dot matrix data corresponding to the nozzle. The printing parameters are used to control the ejection state of each nozzle. After image dot matrix data corresponding to one type of nozzle is set, each printing parameter in the image dot matrix data is read respectively, and each printing parameter is sent to the corresponding nozzle so as to control the jetting state of the nozzle.

In one embodiment, the printing parameters include four numbers 0, 1, 2, and 3, and when a nozzle receives a printing parameter of 0, the nozzle does not eject an ink droplet; when a nozzle receives a printing parameter of 1, the nozzle ejects a small-dot ink drop; when a nozzle receives a print parameter of 2, the nozzle ejects a midpoint ink droplet; when a nozzle receives a printing parameter of 3, the nozzle ejects a large-dot ink drop, and the image dot matrix data corresponding to each nozzle is a dot matrix consisting of four data of 0, 1, 2 and 3.

In one embodiment, step S1 includes: acquiring a line of image dot matrix data of each nozzle in the plurality of nozzles, and splitting the line of image dot matrix data into a group of image dot matrix data aiming at any line of the image dot matrix data, wherein the group of image dot matrix data comprises n lines of image dot matrix data, and n is the row number of the nozzle corresponding to the line of image dot matrix data.

Inkjet printers typically have multiple rows of any of a variety of nozzles. The image dot matrix data corresponding to each of the nozzles includes data corresponding to each of the plurality of rows of the nozzles so that each of the plurality of rows of the nozzles is controlled using the image dot matrix data corresponding to the nozzle.

The method comprises the steps of firstly obtaining one-line image dot matrix data of any one nozzle, then utilizing the one-line dot matrix data to split and form one image dot matrix data for controlling each nozzle in a plurality of rows of the nozzles, and being capable of improving the generation efficiency of the image dot matrix data corresponding to the nozzles and further improving the printing efficiency of the ink-jet printer.

Step S2: and respectively writing the acquired dot matrix data of each image into an internal buffer.

After each image dot matrix data is written into the internal buffer, each image dot matrix data is distributed in an array in the buffer area of the internal buffer. The spraying state of the row of nozzles can be controlled by reading a line of data in each data distributed in the array in the internal buffer area and sending the line of data to the corresponding row of nozzles.

Because the buffer area of the internal buffer can write in the multi-line image dot matrix data at the same time, in the printing process, the printing can be realized only by reading the written image dot matrix data, the problem of poor printing efficiency caused by receiving and processing the acquired image dot matrix data during printing is avoided, and the printing efficiency can be further improved.

In one embodiment, the internal buffer has a plurality of internal buffers, and for any one of the nozzles, the internal buffer has an internal buffer corresponding to the nozzle.

In step S2, for any nozzle of the plurality of nozzles, the acquired image dot matrix data corresponding to the nozzle is written into the corresponding internal buffer area of the nozzle in the internal buffer.

The internal buffer corresponding to this kind of nozzle is: and the internal buffer area is only used for writing the image dot matrix data corresponding to the nozzle.

By writing the image dot matrix data corresponding to each nozzle in the plurality of nozzles into different internal buffer areas in the internal buffer respectively, the image dot matrix data of each buffer area can be read respectively, and the data of each buffer area is utilized to realize the respective control of each nozzle.

In one embodiment, the plurality of nozzles includes red ink nozzles 001, blue ink nozzles 002, and black ink nozzles 003. As shown in fig. 3, the first head 007 is provided with a first red ink nozzle region 004, a first blue ink nozzle region 005, and a first black ink nozzle region 006. A plurality of red ink nozzles 001 arranged in a row are provided in the first red ink nozzle region 004, a plurality of blue ink nozzles 002 arranged in a row are provided in the first blue ink nozzle region, and a plurality of black ink nozzles 003 arranged in a row are provided in the first black ink nozzle region. The red ink nozzle 001 is for ejecting red ink, the blue ink nozzle 002 is for ejecting blue ink, and the black ink nozzle 003 is for ejecting black ink.

The image dot matrix data for the red ink nozzles 001 can be represented by a matrix a, the image dot matrix data for the blue ink nozzles 002 can be represented by a matrix B, and the image dot matrix data for the black ink nozzles 003 can be represented by a matrix C.

As shown in fig. 4, the internal buffer includes a first internal buffer area 01, a second internal buffer area 02, and a third internal buffer area 03. The first internal buffer area 01 is used for writing image dot matrix data corresponding to the red ink nozzle 001, the second internal buffer area 02 is used for writing image dot matrix data corresponding to the blue ink nozzle 002, and the third buffer area 03 is used for writing image dot matrix data corresponding to the black ink nozzle 003.

Step S2 includes: the acquired image dot matrix data corresponding to the red ink nozzle 001 is written into the first internal buffer area 01, the acquired image dot matrix data corresponding to the blue ink nozzle 002 is written into the second internal buffer area 02, and the acquired image dot matrix data corresponding to the black ink nozzle 003 is written into the third internal buffer area 03.

Independent control of the red ink nozzles 001 is achieved by the first internal buffer 01. Independent control of the blue ink nozzles 002 is achieved by the second internal buffer 02. Independent control of the black nozzles 003 is achieved by the third internal buffer 03. If trigger parameters are set for the first internal buffer area 01, the second internal buffer area 02, and the third internal buffer area 03, the red ink nozzle 001, the blue ink nozzle 002, and the black ink nozzle 003 can be independently controlled by the trigger parameters.

In one embodiment, step S2 is followed by: for any nozzle in the plurality of nozzles, setting a trigger parameter corresponding to the nozzle for generating a trigger signal for starting the nozzle to eject ink.

The trigger parameters corresponding to this type of nozzle are: only for controlling the triggering parameters of such nozzles.

In one embodiment, the plurality of nozzles includes a first type of nozzle.

Step S2 is followed by: and changing the trigger parameter corresponding to the first nozzle, and further changing the injection starting time of the first nozzle.

Aiming at a nozzle, the triggering parameters of the nozzle are as follows: the triggering parameters corresponding to such nozzles.

In one embodiment, after step S2, changing the triggering parameter of the first nozzle, and thus changing the injection start time of the first nozzle, includes: after setting a trigger parameter for any one of a plurality of kinds of nozzles and making the trigger parameter of the nozzle different from the trigger parameters of other kinds of nozzles, the trigger parameter of the first kind of nozzle is changed, and the injection start time of the first kind of nozzle is changed.

In one embodiment, by writing the image dot matrix data corresponding to each nozzle in the plurality of nozzles into different internal buffer areas in the internal buffer respectively, the storage of the image dot matrix data corresponding to different nozzles can be triggered respectively, so that the relative position relationship of the patterns printed by various types of nozzles on the printing medium can be changed.

When the printing medium is paper, characters on the paper can be printed by the black ink nozzle 003, red stamps on the paper can be printed by the red ink nozzle 001, and blue stamps on the paper can be printed by the blue ink nozzle 002. The image dot matrix data corresponding to the red ink nozzle 001, the image dot matrix data corresponding to the blue ink nozzle 002, and the image dot matrix data corresponding to the black ink nozzle 003 are written into different buffer areas of the internal buffer, respectively. Then, different trigger parameters are set for the image dot matrix data corresponding to the red ink nozzle 001, the image dot matrix data corresponding to the blue ink nozzle 002, and the image dot matrix data corresponding to the black ink nozzle 003, respectively, so that the ejection start times of the red ink nozzle, the blue ink nozzle, and the black ink nozzle can be made different from each other.

When the first nozzle is a red ink nozzle 001 of three nozzle types, the start ejection time of the red ink nozzle 001 can be changed by changing the trigger parameter of the image dot matrix data of the red ink nozzle 001, so that the time interval between the start ejection time of the red ink nozzle 001 and the start ejection time of the black ink nozzle 003 is changed, and the position of a red chapter printed on paper is different.

When the first nozzle is the blue ink nozzle 002 of three nozzle types, the start ejection time of the blue ink nozzle 002 can be changed by changing the trigger parameter of the image dot matrix data of the blue ink nozzle 002, so that the time interval between the start ejection time of the blue ink nozzle 002 and the start ejection time of the black ink nozzle 003 is changed, and the position of the blue chapter printed on the paper is different. Step S3: and respectively reading data from the image dot matrix data corresponding to at least two nozzles written in the internal buffer, and respectively sending the read data to the nozzles.

Sending each read data to a corresponding nozzle respectively, comprising: for any one of at least two kinds of nozzles, the read data corresponding to the kind of nozzle is sent to the kind of nozzle. Such nozzles, upon receiving data, will eject ink in accordance with the data.

In one embodiment, step S3: and simultaneously respectively reading data from the image dot matrix data corresponding to at least two nozzles written in the internal buffer and respectively sending the data to the nozzles.

In the inkjet printing process, when the pattern to be printed is generally of a plurality of colors or a plurality of resolutions, it is often necessary to print the patterns of the respective colors or the respective resolutions separately. This requires the head to make multiple reciprocating movements over the print medium and to print one pattern during each movement, thereby printing out various patterns on the print medium step by step. Therefore, each time the nozzle moves in the reciprocating process, the idle rate is high, which causes the printing efficiency of the inkjet printer to be low, and the printing process is time-consuming and labor-consuming.

In response to the above situation, a plurality of nozzles for printing different patterns on a printing medium are provided in an inkjet printer. The plurality of nozzles include nozzles capable of printing different color patterns, respectively. And the data are respectively read from the image dot matrix data corresponding to at least two kinds of nozzles at the same time, and the read data are respectively sent to the corresponding nozzles, so that the ink-jet printer can simultaneously print different types of patterns in one moving process, and the printing efficiency of the ink-jet printer is improved.
