Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, 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 merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may 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 present invention.

It should be noted that, in this document, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of another like element in a process, method, article, or apparatus that comprises the element.

At present, in the working process of an industrial ink-jet printer, a printer nozzle sprays ink drops to form pictures and texts in an image to be printed. In the area where the two spray heads are spliced, because the trolley moves during printing, a wind wall is easily formed at the spliced part of the two spray heads. Because the air flow speed in the air wall is higher than the air flow speed around, the air pressure is lower, ink drops sprayed from the holes at the edge of the splicing part of the two nozzles are easily sucked into the air wall, and are overlapped in a cross way, so that the ink volume concentration at the overlapping part is higher than that around, and a dark splicing channel is visually formed, which is called as a black channel.

As shown in fig. 1, the dotted rectangle in the figure indicates that, during printing, due to the influence of external factors, two rows of ink drops fall on the back of the dot, and overlapped ink dots appear, visually presenting an elongated "black channel" with a darker color than the surroundings.

The invention provides a method, a device, equipment and a storage medium for eliminating a nozzle splicing channel, which can solve the phenomenon of ink dot overlapping to a certain extent.

An embodiment of the present invention provides a method for eliminating a spliced channel of a nozzle, as shown in fig. 2, the method includes the following steps S1 to S2.

Step S1: a print data set is obtained, the print data set including a first data set and a second data set.

The first data set corresponds to a first area in the image to be printed and is used for controlling the first nozzle to print the first area. The second data set corresponds to a second region in the image to be printed for controlling the second nozzle to print the second region. The first spray head is adjacent to the second spray head, and the first spray head and the second spray head are spliced and overlapped. The distance between the first area and the second area is smaller than or equal to a set distance. The set distance is equal to or greater than 0.

The print data set includes data for controlling the ejection of ink from the head. During printing, the ink jetting amount of the nozzle is controlled by the printing data set.

In the printing process, the nozzles in the spray head respectively print different areas in the image to be printed. The amount of ink ejected by the heads in each of the different areas may be different for printing to form the image to be printed. When the ink quantities of two areas in the image to be printed are different, the printing data sets respectively corresponding to the two areas are controlled to be different by the nozzle.

The method comprises the steps that a printing data set is obtained, wherein the printing data set comprises a first data set and a second data set, and the first data set and the second data set can be processed to obtain a first snapshot data set and a second snapshot data set; the ink jetting amount corresponding to the first snapshot data set is less than the ink jetting amount corresponding to the first data set, and the ink jetting amount corresponding to the second snapshot data set is less than the ink jetting amount corresponding to the second data set.

In the printing process, in order to improve the printing speed, a plurality of spray heads are usually spliced and are simultaneously printed by utilizing the plurality of spray heads which are spliced into a whole. And a black channel is printed and formed on the area of the printing medium corresponding to the splicing position of the two adjacent spray heads. The printing data set corresponding to the area below the nozzle splicing position in the printing process in the image to be printed is obtained, and the printing data set is processed, so that the black channel generated in the area below the nozzle splicing area in the printing process in the image to be printed can be prevented.

And a boundary between the first area and the second area is positioned below the splicing position of two adjacent spray heads, and a black channel is printed and formed at the boundary between the first area and the second area in the printing process.

In one embodiment, the first area is located in an area of the image to be printed, which is printed by one of two adjacent nozzles, and a distance between the first area and a boundary of the second area is smaller than a fifth setting value. Said fifth set value is equal to 0.5mm.

In an embodiment, the second area is located in an area printed by one of two adjacent nozzles in the image to be printed, and a distance between the second area and a boundary between the first area and the second area is smaller than a sixth preset value. Said sixth set value is equal to 0.5mm.

In one embodiment, as shown in fig. 3, two adjacent nozzles include a first nozzle 1 and a second nozzle 2. In order to increase the printing speed, the first nozzle 1 and the second nozzle 2 are usually spliced to print. The first spray head 1 is one of two adjacent spray heads, and the second spray head 2 is the other of the two adjacent spray heads. The spliced first nozzle 1 and the spliced second nozzle 2 usually have nozzles with overlapped printing areas in normal printing. The first ejection head 1 has a first boundary line 4 at a position adjacent to the second ejection head 2. The first spray head 1 further comprises a third borderline 8 parallel to the first borderline 4. The second sprinkling head 2 has a second borderline 3 at a position adjacent to the first sprinkling head 1. The second sprinkling head 2 further comprises a fourth borderline 9 parallel to the second borderline 3. The first 4 and second 3 borderlines are parallel to the paper-feeding direction 6. A centre line 5 is present between the first 4 and the second 3 border line. The centre line 5 is at a distance from the first borderline 4 and from the second borderline 3 in a direction perpendicular to the paper advance direction 6.

The paper feeding direction 6 is a relative moving direction of the printing medium and the first head 1.

The first head 1 prints with nozzles located between the centre line 5 and the third borderline 8. The second head 2 prints with nozzles located between the centre line 5 and the fourth borderline 9. The borderlines of the first and second areas coincide with the centre line 5. The edge lines at a distance m from the boundary line coincide with a first straight line 10 below the centre line 5 and with a second straight line 7 above the centre line 5, respectively, m being 0.5mm. The first area and the second area are located directly below the area between the first line 10 and the middle line 5 and the area between the second line 7 and the middle line 5, respectively, in the image to be printed. The dots within the dashed box in fig. 1 are located directly below the center line 5.

Step S2: processing the first data set and the second data set to obtain a first snapshot data set and a second snapshot data set; the ink jetting amount corresponding to the first snapshot data set is less than the ink jetting amount corresponding to the first data set, and the ink jetting amount corresponding to the second snapshot data set is less than the ink jetting amount corresponding to the second data set.

The black mark formed by printing at the position of the boundary line between the first area and the second area in the image to be printed is caused by a large amount of ink ejected to the boundary line. By processing the first data set and the second data set, the ink ejection amount of the first area and the second area can be reduced, and the formation of a black line by printing at the boundary between the first area and the second area can be prevented.

In one embodiment, the print data set includes data that controls the nozzles to eject a first set amount of ink.

In step S2, processing the first data set and the second data set to obtain a first snapshot data set and a second snapshot data set; the ink jetting amount corresponding to the first snapshot data set is less than the ink jetting amount corresponding to the first data set, the ink jetting amount corresponding to the second snapshot data set is less than the ink jetting amount corresponding to the second data set, and the method includes: controlling the nozzle to jet partial data of a first set amount of ink in the first data set or the second data set to process to obtain a first snapshot data set and a second snapshot data set; the ink jetting amount corresponding to the first snapshot data set is less than the ink jetting amount corresponding to the first data set, and the ink jetting amount corresponding to the second snapshot data set is less than the ink jetting amount corresponding to the second data set. The first set value is greater than 0.

During printing, each data in the first data set and the second data set respectively controls a nozzle in the spray head to spray ink. The ink ejected from each nozzle solidifies to form dots in the image to be printed. Each nozzle ejects each formed dot in a different area of the image to be printed to form the image to be printed.

The size of the ink dots formed by ejection in the image to be printed may vary. When the head performs one ejection, if data for controlling one nozzle is different from data for controlling the other nozzles, the amount of ink ejected from the nozzle may be different from the amount of ink ejected from the other nozzles. By modifying the print data set, the amount of ink ejection from the nozzles controlled by the print data set can be changed.

The first set amount is an amount of ink ejected by the nozzles under control of the print data set. When the print data set includes data for controlling the nozzles to eject a first set amount of ink, the nozzles in the head will eject ink drops of the first set amount under control of the data for controlling the nozzles to eject ink of the first set amount during printing.

Controlling the nozzle to jet partial data of a first set amount of ink in the first data set or the second data set to process to obtain a first snapshot data set and a second snapshot data set; the ink ejection amount corresponding to the first snapshot data set is less than the ink ejection amount corresponding to the first data set, the ink ejection amount corresponding to the second snapshot data set is less than the ink ejection amount corresponding to the second data set, and the data for controlling the ejection of the first set amount of ink can be changed into the data for controlling the nozzles not to eject the ink or the data for controlling the nozzles to eject the amount of ink smaller than the first set amount, so that the purpose of preventing the generation of black channels below the head splicing position can be achieved.

In one embodiment, the first data set and/or the second data set comprises: image dot matrix data including a data set of one or more control nozzles ejecting the first set amount of ink, the data set in the image dot matrix data corresponding to each pixel of an original image, the first set amount being greater than 0.

The original image is processed to form image dot matrix data. The data processing is performed on each pixel in the original image, and image dot matrix data can be processed and formed.

The data group in the image dot matrix data corresponds to each pixel of the original image, and the method comprises the following steps: for any data set in the image dot matrix data, the position order of the data set among the data sets in the image dot matrix data is the same as the position order of the original image pixels processed to form the data set among the pixels in the original image.

If no printing error exists, the original image is the same as the image to be printed which is printed and formed according to the image dot matrix data.

In step S2, processing the first data set and the second data set includes: and changing one data set in the image dot matrix data to the data set corresponding to the ink jetting amount smaller than the first set amount, wherein the ink jetting amount corresponding to the data set before the change is the first set amount, and the data set is adjacent to at least one data set corresponding to the ink jetting amount which is the first set amount.

The ink jet amount corresponding to one data set is the ink amount jetted by the nozzle controlled by the data set.

Through will control the nozzle sprays first setting amount printing ink, and with at least one control the nozzle sprays first setting amount printing ink the data set that the data set is adjacent changes into the data set that control nozzle jet printing ink volume is less than first setting amount, can make the image color that prints according to the image dot matrix data after the processing more even, obvious black track or black spot can not appear.

Changing one of the image dot matrix data to the data set in which the corresponding ink ejection amount is smaller than the first set amount, the data set controlling the nozzles to eject the ink in the first set amount before the change, the data set being adjacent to at least one of the data sets in which the corresponding ink ejection amount is the first set amount, includes: traversing each of the data sets in the image dot matrix data, changing any one of the data sets in the image dot matrix data to the data set whose corresponding ink ejection amount is smaller than the first set amount, where the ink ejection amount corresponding to the data set before the change is the first set amount, and the data set is adjacent to at least one of the data sets whose corresponding ink ejection amount is the first set amount.

The data set includes one or more data of the image dot matrix data.

The image dot matrix data includes a plurality of data sets distributed in an array, each data set corresponding to a nozzle in the head. During printing, the image dot matrix data is stored in an internal buffer provided on the data processing board. And the spray head control module is used for sequentially reading the data groups from the internal buffer, and controlling the spray head to perform ink jet output action by using the corresponding nozzles of the data groups in the read data groups after each data group is read. The data set includes one or more data of the image dot matrix data.

In one embodiment, the image lattice data is generated from raw image processing. The original image is the same as or similar to the image to be printed to be formed.

The data sets in the image dot matrix data correspond to the original pixels. When a pixel in an image to be printed is formed by printing one data in the image dot matrix data, the data group includes one data. The position order of any data in the image dot matrix data is the same as the position order of the pixels processed to form the data in the original image. If no printing error exists, the image to be printed which is the same as the original image can be printed in the image to be printed according to the image dot matrix data.

In one embodiment, the image dot matrix data is composed of

data sets

00, 01, 10, 11. One line of data in the image dot matrix data corresponds to one row of nozzles in the head. And after acquiring a line of data in the image dot matrix data, the spray head control module controls a row of nozzles in the spray head to spray ink by using each data group in the line of data. When the data set corresponding to a nozzle in the nozzle is 00, the nozzle control module controls the nozzle not to eject ink. When a data set received by a nozzle in the nozzle is 01, the nozzle control module controls the nozzle to jet a third set amount of ink. When a data set received by a nozzle in the head is 10, the head control module controls the nozzle to eject a second set amount of ink. When a data set received by a nozzle in the head is 11, the head control module controls the nozzle to eject a first set amount of ink. Wherein the first set amount is greater than the second set amount, which is greater than the third set amount.

The image dot matrix data is obtained from the internal buffer, one or more data groups in the obtained image dot matrix data are processed, the processed image dot matrix data are stored in the internal buffer at the position where the image dot matrix data before processing are stored, the processed image dot matrix data can be used for controlling the spray head to spray, and the ink spraying amount of the spray head sprayed by the processed image dot matrix data is smaller than that sprayed by the image dot matrix data before processing.
