In a preferred embodiment of the present invention, the offset parameter may be obtained by using the technical solution shown in fig. 3, which includes steps S211 to S213.
S211: and acquiring the generation time of the task trigger signal and recording the generation time as a first moment.
S212: and acquiring the time when the nozzle control board acquires the task trigger signal, and recording as the second moment. As described above, for the head control board that generates the task trigger signal, the time when the task trigger signal is generated is the time when the task trigger signal is acquired (the first time and the second time may be considered to be the same); for other spray head control boards, the time when the task trigger signal is received is the time when the task trigger signal is acquired.
S213: and acquiring an offset parameter according to the time difference between the first time and the second time. Specifically, if the same task creation time is obtained, the offset parameter may be determined according to a time difference between the first time and the second time. For ease of understanding, the following examples are given by way of illustration of embodiments of the present invention.
In one embodiment, the Onepass printing apparatus includes a total of 3 head control boards, referred to as head control board P1, head control board P2, and head control board P3, and now determines offset parameters X1, X2, and X3 corresponding to the head control board P1, head control board P2, and head control board P3. The spray head control board P1 is used for generating a task trigger signal, the time for generating the task trigger signal is T1, and the time for sending the task trigger signal to the spray head control board P2 and the spray head control board P3 is T2 and T3 respectively. Wherein T1< T2< T3. Respectively acquiring time difference between the time when the spray head control board acquires the task trigger signal and the time when the task trigger signal is generated, wherein the time difference is 0 for the spray head control board P1 and T2-T1 for the spray head control board P2; for the showerhead control plate P3, the time difference is T3-T1. Then, the offset parameter may be determined by using X1 ═ X2+ (T2-T1) ═ X3+ (T3-T1), where in a preferred embodiment of the present invention, X3 is usually set to 0, that is, the offset parameter corresponding to the head control board that last received the task trigger signal is set to 0. Of course, in other embodiments of the present invention, the offset parameter may be set to any non-negative number.
Of course, in one embodiment of the present invention, the offset parameter may also be obtained by a task creation time set as desired. For example, it is expected that the task creation time of the head control board P1, the head control board P2, and the head control board P3 are all T4, and T1< T2< T3< T4, the following technical solutions may be adopted: T4-T1 + X1-T2 + X2-T3 + X3 to determine the offset parameter.
In another embodiment of the present invention, the offset parameter may also be obtained by printing the white edge parameter. Referring to FIG. 4, steps S214-S215 are included.
S214: and controlling a nozzle control board to respectively acquire printing white edge parameters, wherein the printing white edge parameters are used for adjusting the printing white edges of the printed images.
S215: and controlling the spray head control board to obtain the offset parameter according to the printing white edge parameter.
And acquiring an offset parameter according to a printing white edge parameter of the printing task, wherein the printing white edge is a blank area adjacent to the edge of the printing image formed by printing according to the printing task. Through setting up the printing white limit at the edge of printing the image, can realize very conveniently cutting out to printing the image according to printing the white limit, through setting up the printing white limit at the edge of printing the image, also can promote the display effect of printing the image, it is more pleasing to the eye.
By controlling the job creation time of a print job, it is possible to make a print margin exist at the edge of a print image formed by printing according to the print job. When the offset parameter is set, the offset parameter can be increased so that a printing margin exists at the edge of a printing image formed by printing, so that the printing margin is formed between different printing images of the printing medium after the job creation time is delayed according to the offset parameter.
As shown in fig. 5A, if the next print job is created for printing immediately after the previous print job is completed, the interval between the print images 1 obtained by 2 prints will be very small, and even the partial overlap will be caused by mechanical error, which affects the printing effect and is not beneficial to cutting.
As shown in fig. 5B, the offset parameter is obtained by printing the white edge parameter, so that each nozzle control board delays for a certain time to create a print job, and the printing medium 2 moves for a certain distance under the working condition that the nozzles 3 do not eject ink, thereby realizing accurate control of printing the white edge. For example, in order to make the moving time of the printing medium 2 in the non-ink-ejection condition of the nozzle 3 be T6 to reserve a printing white edge, the offset parameter X3 may be T6.
In another embodiment of the present invention, a fixed offset parameter can be set for each head control board to simplify the process of obtaining the offset parameter.
In the industrial printing field, the same printing equipment prints the same product for a long time, parameters such as printing blank edges and the like do not need to be changed for the same product generally, and the delay possibly existing when each spray head control board receives a task trigger signal is also fixed for the same printing equipment. Therefore, a set of fixed offset parameters can be set for the spray head control board in the printing equipment, so that the consistency of products is kept in the production of hydration, the flow of acquiring the offset parameters can be simplified, and the printing efficiency is improved. When the printing device is applied to other products, the fixed offset parameters are adjusted, so that the proper offset parameters can be acquired according to production requirements.
In another embodiment of the invention, external input can be acquired as the offset parameter, so that the task creation time of the printing task can be flexibly regulated and controlled through the offset parameter. For example, under certain conditions (e.g., detecting the operating condition of the stage), it is necessary to keep the printing apparatus operating without performing inkjet printing, which can be achieved by setting a larger offset parameter.
In an embodiment of the present invention, in the aforementioned S10, the controlling 1 of the head control boards to generate the task trigger signal includes: and controlling the spray head control plate which finishes the last printing task firstly in the spray head control plates to generate a task trigger signal. By adopting the technical scheme, the printing can be performed according to the created printing task after the last printing task is finished, and the printing efficiency is improved.
In Onepass printing, the jets often need to print color stripes on the print media to remain wet. In order to enable the color bar to be spaced from the printed image at a certain distance, the prior art scheme is to insert null data between the print data corresponding to the printed image and the print data corresponding to the color bar. By adopting the Onepass printing control method provided by the embodiment of the invention, when the printing task for printing the color bar is created, the distance between the color bar and the printing image is adjusted by setting the offset parameter, the method is simple and convenient, the printing data does not need to be processed, and the time interval between the printing task for creating the color bar each time and the printing task for printing the image at the last time can be flexibly adjusted and controlled by the offset parameter.
In one embodiment, the offset parameter may also be obtained according to a correlation between a print job created by the job trigger signal and a previous print job.
The last printing task comprises the last printing task which is before the printing task created by the control spray head control board according to the task trigger signal and is adjacent to the printing task created according to the task trigger signal.
The correlation of the printing task created according to the task trigger signal and the previous printing task comprises the following steps: on the printing medium, the relative positional relationship between an image printed according to the last print job and an image printed according to a print job created from the job trigger signal.
After the control nozzle control board acquires the task trigger signal, the task creation time of the next printing task is acquired according to the correlation between the previous printing task and the next printing task to be printed, and the printed images printed by two adjacent printing tasks can be prevented from overlapping or color register deviation.
In one embodiment, the method further comprises controlling the spray head control board to obtain an offset parameter according to a mechanical error between the spray heads.
For a printing device, there may be a processing error in a nozzle or an installation error between nozzles, which may cause a color error between printed images printed by the nozzles, and affect the printing effect of the printed images.
When the offset parameters are generated, the offset parameters for compensating the errors are generated through the mechanical errors among the nozzles, so that the nozzles can print more accurately according to the offset parameters, and the printing effect of printed images is improved.
In one embodiment, the print jobs of each head control board correspond to different portions of the same print image. And setting the offset parameter by controlling the spray head control board according to the correlation between the corresponding printing task and the printing tasks corresponding to other spray head control boards. The correlation between the print jobs includes a relative positional relationship between portions of the print image corresponding to the print jobs.
