Example 1
As shown in fig. 1, the present embodiment discloses a head moisturizing printing control method for printing moisturizing images between specified adjacent target print images when printing a plurality of target print images, the method including the steps of:
s1: acquiring the number of the moisturizing images to be inserted in the printing process of the multiple target printing images, the inserting position and the size of each moisturizing image on a printing medium;
wherein this step acquires some parameters related to the print job, such as the number of print images of the print target, the position where the print images of the print target are printed, whether or not to print the moisturizing image, and the like. The moisturizing image in the present embodiment refers to an additional image obtained by adding printing to keep the nozzle of the head in a wet state on the basis of the target print image to be originally printed. In ink jet printing, the print medium is moved in a direction relative to the head, and the target print image is usually in multiple copies. As shown in fig. 2, a plurality of target print images are arranged at intervals in the print medium moving direction (the direction indicated by the arrow a in fig. 2), and the moisturizing image of the present embodiment is located between two adjacent target print images. Namely, the moisturizing image is inserted into the middle of the target printing image for printing.
The printing task parameters of the moisturizing images to be printed further comprise parameters such as the number of interval printing copies of the moisturizing images, the size of the moisturizing images, the distance between the moisturizing images and the like. The number of the interval printing copies of the moisturizing images refers to the number of target printing images printed at intervals of the moisturizing images. For example, if the number of printed copies of the moisturizing image is 4, the moisturizing image may be printed every 4 target printed images, and the moisturizing image may be printed in 1 copy or in multiple copies, which is not limited herein. The number of intermittent print copies may be other values, and is not limited herein. Further, the number of intermittent print copies may be a fixed value, for example, a moisturizing image is printed every 5 copies of the target print image. The number of intermittent print copies may be a changeable value, for example, a moisturizing image is printed after 3 target print images are printed for the first time, a moisturizing image is printed after 4 target print images are printed for the second time, and a moisturizing image is printed after 6 target print images are printed for the third time, where the manner of changing the number of intermittent print copies may be set according to an actual print scene, and is not limited herein.
The size of the moisturizing image refers to the length and width of the moisturizing image, wherein the direction of the length is the moving direction of the printing medium. The width direction is a direction perpendicular to the moving direction of the printing medium. As d1 in fig. 2 denotes the width of the moisturizing image, d2 denotes the width of the printing medium, and L denotes the width of the target printing image.
Wherein the pitch of the moisturizing images refers to a distance between the moisturizing images and the target print image adjacent thereto, which is spaced in the moving direction of the printing medium.
The printing task parameters can be issued to a control system of the printing equipment by an upper computer. The user can set the printing task parameters through the interactive interface of the upper computer.
S2: when the image is printed to an insertion position where a moisturizing image needs to be inserted, acquiring printing data corresponding to the moisturizing image;
this step can acquire the number of copies of the target print image that has currently finished printing in the printing process. The number of copies of the printed target print image is monitored in the printing process, specifically, the printed target print image is counted, the count value is started from 0, and the count value can be increased by 1 after each copy of the target print image is printed. The number of copies of the target print image which has been printed at present can be obtained by acquiring the current calculated value in the printing process. The current printing mode can be determined according to the printing task parameters and the number of copies of the printed target printing image;
the current printing mode comprises a target printing image printing mode and a moisturizing image printing mode, wherein the target printing image printing mode refers to the current printing of only the target printing image, and the moisturizing image printing mode refers to the current printing of the moisturizing image.
Judging whether the number of printed moisturizing images is reached currently or not according to the interval printing number of moisturizing images in the printing task parameters and the number of printed target printing images which are finished to be printed currently; as shown in fig. 4, the specific determination method is:
acquiring the number n of printed target images;
acquiring the interval printing number m of the moisturizing images;
judging whether n = k × m is satisfied, wherein m, n and k are positive integers;
if the number of copies of the target print image which has been printed at present has reached the number of copies of the print moisturizing image, and if the number of copies of the target print image which has been printed at present has not reached the number of copies of the print moisturizing image.
When the interval printing number of copies m of the moisturizing image is not changed, whether the moisturizing image needs to be printed currently or not can be judged by calculating whether the number of copies n of the target printing image which is printed currently is integral multiple of the interval printing number of copies m of the moisturizing image or not through the steps.
If the number m of interval printing copies of the moisturizing image can be changed, the moisturizing image is calculated according to each interval printing copy number and is printed after the completion of the several target printing images. And then the moisturizing image is printed after the number of copies of the target print image which has been printed at present reaches the corresponding number of copies.
And if the number of printed moisturizing images reaches the number of copies of the moisturizing images currently, the current printing mode is a moisturizing image printing mode, and the printing medium moves to an insertion position where the moisturizing images need to be inserted.
And if the number of copies of the printed moisturizing image is not reached currently, the current printing mode is the target printing image printing mode. The current printing position prints only the target print image.
S3: outputting printing data corresponding to the moisturizing image in the size range to print the moisturizing image; wherein the moisturizing image is an image printed to keep the head wet.
The embodiment can enable the spray head to still spray ink when the spray head does not print the target printing image by inserting the moisturizing image into the target printing image to print in the position, so that the spray head is kept moist, and the blockage of the spray head is avoided. Because the moisturizing image is positioned between the two adjacent target printing images, the printing process of the moisturizing image does not influence the printing length, position and printing process of the normal image, and in addition, the moisturizing image can be used for detecting the state of the nozzle and the accuracy of the color of the spray head, so that the detection can be carried out while printing, and the real-time detection in the printing process is realized. The moisturizing image can be a color bar image or a color patch image. The color bar image is shown in fig. 5, and the image is composed of different color bars, each color bar is printed by one color, for example, the nozzles are divided into four groups, and each group respectively ejects four colors of ink, namely cyan ink (C), magenta ink (M), yellow ink (Y), and black ink (K). At least four color bars are printed in the moisturizing image, and the colors of the four color bars are C, M, Y and K respectively. The moisturizing image can be any one of single color and mixed color, and the color of the moisturizing image is not limited.
As shown in fig. 3, in the present embodiment, the S2: when the image is printed to an insertion position where a moisturizing image needs to be inserted, acquiring printing data corresponding to the moisturizing image comprises the following steps:
s21: and acquiring first printing data, wherein the first printing data are corresponding printing data of the printing target printing image and the moisturizing image.
Before this step, the printing device may store first print data, where the first print data may be obtained by inputting the target print image and the moisturizing image into raster image processing software for rasterization.
S22: and performing ink non-discharge processing on the printing data corresponding to the target printing image in the first printing data to obtain the printing data corresponding to the moisturizing image.
Wherein the ink non-discharge processing of the print data corresponding to the target print image in the first print data means setting data for printing the target print image in the first print data to 0. Specifically, the data for printing the target print image in the second print data and the matrix having 0 elements and the same size as the data for printing the target image in the first print data may be subjected to an and operation, so that the data is masked, and thus, only the moisturizing image is printed when printing.
This step may generate print data corresponding to the moisturizing image according to the size, color information, and the like of the moisturizing image in the print job parameter. Wherein the color information means that the moisturizing image is a mixed color or a single color or multiple colors. When the spray head prints the first printing data, namely prints the moisturizing image, each nozzle carries out ink jet operation in the process of printing at least a part of the moisturizing image, and therefore each nozzle is in a wet state.
In this embodiment, the method for controlling the moisturizing printing of the nozzle further includes the following steps:
s101: when the target printing image is printed to the position where the target printing image needs to be printed, second printing data is obtained, and the second printing data is printing data corresponding to the target printing image; the first print data may be obtained by performing ink non-discharge processing on print data corresponding to the moisturizing image data.
S102: and outputting second data to print the moisturizing image.
By adopting the printing method of the embodiment, the moisturizing image can be inserted between the original printing images for printing only by storing one group of first printing data, so that the storage space can be further reduced.
A wet image printing mode for printing a target print image, and a moisturizing image printing mode for printing a print image including a moisturizing image.
The embodiment also supports a printing mode of dynamically modifying the number of copies printed at intervals in the printing process, and the mode is that in S3: after the execution, the method also comprises the following steps:
s4: monitoring whether interval number adjusting information is received or not;
s5: and if the interval copy number adjusting information is received, adjusting the interval printing copy number of the moisturizing image in the printing task parameter according to the interval copy number adjusting information. The interval copy number adjustment information includes the adjusted interval print copy number of the moisturizing image.
After the execution of S6 is completed, S2 to S5 may be repeatedly executed until all the print images of the present print job are printed.
For example, the number of print copies of the moisturizing image at intervals in the original print parameters is 5, that is, 1 moisturizing image is printed every 5 print copies of the target print image. If the interval printing number adjusting information is received, for example, the interval printing number of the adjusted moisturizing images is 4, the interval printing number of the moisturizing images in the printing task parameters is adjusted to be 4. And printing the adjusted moisturizing images at intervals according to the printing number of the moisturizing images in the subsequent printing process.
Since a print job interruption may occur or occur during printing, the head is likely to be clogged in a state where ink is not ejected during the print job interruption. For this embodiment, whether the print interruption signal is received is detected in the process of S1 to S3, as shown in fig. 6, if the print interruption signal is received, the method further includes the following steps:
s01: interrupting the current printing task;
s02: acquiring the current printing progress and the estimated printing interruption time;
if the printing is interrupted and the target printing image or the moisturizing image is not being printed, the current printing progress is represented by acquiring the number of copies of the printing target printing image and the number of copies of the moisturizing image which have been printed at present. If the print target image is being printed or the moisturizing image is being printed while being interrupted, it is necessary to acquire the data amount of the currently printed image for which ink jetting has been completed in addition to the already printed print target image and the number of copies of the moisturizing image to moisturize the current printing schedule. The estimated interruption time is a preset time for which the printing interruption process is to be continued. The estimated interruption time can be input by a user, or the estimated interruption time corresponding to the reason can be obtained according to the reason of the interruption.
S03: determining moisturizing image printing data during the interruption period of the printing task according to the current printing progress and the estimated printing interruption time;
if the estimated printing interruption time is longer, the time for printing the moisturizing image is correspondingly longer, and moisturizing image printing data can be designed according to the length of the time for printing the moisturizing image.
S04: the moisturizing image is printed during the interruption of the print job according to the moisturizing image printing data during the interruption of the print job.
Therefore, the spray head can spray ink during the interruption of the printing task, and the blockage of the spray head caused by the interruption of the printing is effectively avoided.
Example 2
As shown in fig. 7, in the present embodiment, in S2: when the image is printed to an insertion position where a moisturizing image needs to be inserted, acquiring printing data corresponding to the moisturizing image further comprises the following steps;
s201: acquiring fourth printing data and fifth printing data, wherein the fourth printing data is corresponding printing data of a moisturizing image, and the fifth printing data is corresponding printing data of a target printing image adjacent to the moisturizing image to be printed currently;
s202: and acquiring the printing ink amount corresponding to the moisturizing image printed by each nozzle according to the fourth printing data as the first printing ink amount M1 of each nozzle.
For example, if the number of nozzles is r, the first printing ink amount M1 corresponding to each nozzle is calculated based on the print data. The first printing ink amount M1 corresponding to the ith nozzle is the amount of ink ejected by the nozzle in the process of printing the moisturizing image.
S203: acquiring printing ink amount corresponding to the target printing image which is printed by each nozzle and adjacent to the currently-printed moisturizing image according to the fifth printing data to serve as second printing ink amount M2 of each nozzle;
that is, the second printing ink amount is the amount of ink ejected by each nozzle when printing an adjacent target print image.
S204: calculating an overall printing ink amount M3 for each nozzle from the first and second printing ink amounts M1 and M2 for each nozzle, wherein M3= M1+ M2;
s205: adjusting the fourth printing data according to the first printing ink amount and the second printing ink amount so that a mean square error of an overall printing ink amount of each nozzle is smaller than a first threshold value.
Since the amount of printing ink differs for each nozzle in printing a target print image, the state of each nozzle also has a large difference. According to the embodiment, the states of the nozzles are adjusted in the test printing process by modifying the printing data of the moisturizing image, and the nozzles are kept at the ink quantities which are not similar in the whole printing process under the condition that the target printing image is not changed, so that certain nozzles are prevented from being blocked due to less ink jetting. Wherein the first threshold value can be set according to actual needs.
As shown in fig. 8, in this embodiment, as a preferable mode, the S205: adjusting the fourth printing data according to the first printing ink amount and the second printing ink amount so that a mean square error of the overall printing ink amount of each nozzle is smaller than a first threshold, comprising the steps of:
s2051: acquiring a part, corresponding to each nozzle, of the moisturizing image, wherein the part is subjected to ink jet operation and serves as a first sub moisturizing image;
s2052: acquiring printing data of the first sub moisturizing image as first sub test printing data;
s2053: acquiring images except the first sub moisturizing image in the moisturizing image as a second sub moisturizing image;
s2054: acquiring printing data of the second sub moisturizing image as second sub test printing data;
s2055: the first sub-test printing data is kept unchanged according to the first printing ink amount and the second sub-test printing data is adjusted so that the mean square error of the overall printing ink amount of each nozzle is smaller than a first threshold value.
In the embodiment, the moisturizing image is divided into two parts for printing, wherein one part is the first sub-test image corresponding to the first sub-test printing data, and the part enables all the nozzles to perform ink jetting operation so as to ensure that the states of all the nozzles and the accuracy of all colors of the nozzles can be accurately detected. The other part is used as a data adjusting part and is adjusted according to the printing ink amount when each nozzle prints the target printing image and the first sub-test image, so that each nozzle can discharge ink more uniformly in the printing process, and the condition that the partial nozzles discharge ink to cause blockage less is avoided.

s23: acquiring the length of each target printing image and the interval length of two adjacent target printing images in the moving direction of a printing medium;
s24: acquiring the moving speed of a printing medium;
s25: determining the time for which the spray head needs to be kept wet according to the interval length and the moving speed of the printing medium;
since the nozzles of the heads are kept in the ink ejection state during printing of the target print image, the present embodiment can determine the time for which each nozzle in the heads maintains the ink ejection state according to the length of each target print image with the print medium moving speed already known. When the nozzle is positioned at the interval position of the two adjacent sub-target printing images, the target printing images are not printed, so that the nozzle can continuously maintain the ink-jet state in a way of printing the moisturizing images, and the nozzle can also keep the moisturizing state to avoid the nozzle blockage when the nozzle does not print the sub-target printing images. In this case, the time during which the heads remain wet can be calculated when the print medium moving speed is known.
S26: and adjusting the printing data corresponding to the moisturizing image according to the time for which the spray head needs to be kept moist.
If the time for which the spray head needs to be kept wet is longer, the length of the moisturizing image can be increased by adjusting the test image printing data, so that the time for the spray head to test and print is delayed, and the time for which the spray head needs to be kept wet is prolonged. On the contrary, the length of the test image can be reduced by adjusting the print data of the moisturizing image, so that the time for testing and printing the spray head is shortened, and the time for keeping the spray head moist is shortened.
Therefore, with the method of the present embodiment, the nozzles can be in a good moisturized state regardless of the variation in the length and the spacing distance of the sub-target print images.
