Example one

Fig. 1 is a flowchart of a printing method according to an embodiment of the present invention, where the embodiment is applicable to a situation where a printing speed of a high-resolution image and/or text needs to be increased, the method may be executed by a printing apparatus, and specifically includes the following steps:

and step 110, determining the maximum spray printing speed and the minimum acceleration and deceleration distance of the spray head.

In the ink jet printing, the nozzle can reciprocate based on a printing medium to realize printing of an image to be printed on the printing medium. The jet printing speed can be the number of dots capable of being jet printed in a preset time, wherein the smaller the point height of the single line is, the faster the jet printing speed is. The acceleration and deceleration distance may be a distance required to accelerate the velocity of the head from 0 to a target printing velocity after the head starts printing.

In particular, it may be based on a formulaDetermining a maximum jet printing speed, wherein V₀The maximum jet printing speed, f the maximum jet printing frequency, N a preset constant related to the jet head, and P the physical resolution of the jet head. Before printing begins, the jet printing speed of the jet head in the direction perpendicular to the moving direction of the printing medium can be determined, and the jet printing speed can be the jet head in the direction perpendicular to the moving direction of the printing medium and the physical resolution of the jet headThe maximum jet printing speed for jet printing. The minimum acceleration/deceleration distance may be a distance required for the printhead to move in a direction perpendicular to the direction of print media movement and accelerate to a desired target print speed. The minimum acceleration and deceleration distance can be determined according to the type and model of the spray head.

In the embodiment of the invention, the physical resolution of the nozzle can be 600dpi, wherein 600dpi indicates that 600 pixel points can be printed within one inch, and dpi is the number of pixel points within each inch of the image. The maximum spray printing frequency of the spray head can be 30KHz, and when the resolution of the image to be printed can be 1800dpi, the maximum spray printing speed of the spray head can be determinedWherein m is meters and s is seconds. Among them, 25.4 may be a predetermined constant associated with the showerhead, and when the showerhead is changed, the predetermined constant may be changed accordingly. In the prior art, the printing of the image to be printed can be realized by adopting the original printing speed of 1.27m/s to and fro three times, at this time, 6 times of acceleration and deceleration are needed for printing one line, the time is long, and the printing speed is slow.

And step 120, determining a target printing speed according to the maximum spray printing speed, the physical resolution of the spray head and the resolution of the image to be printed.

The physical resolution of the nozzle may be an inherent property of the nozzle, and the physical resolution of the nozzle used in the embodiment of the present invention may be 600 dpi.

In particular, it may be based on a formulaDetermining a target printing speed, wherein V_sFor target printing speed, V₀For maximum jet printing speed, R is the resolution of the image to be printed, and P is the physical resolution of the nozzle. After determining the maximum jet printing speed, a multiple of the resolution of the image to be printed with respect to the physical resolution of the ejection head may be first determined, and then a target printing speed may be determined based on the maximum jet printing speed and the aforementioned multiple.

Practice of the inventionIn an example, the maximum printing speed may be 1.27m/s, the physical resolution of the ejection head may be 600dpi, the resolution of the image to be printed may be 1800dpi, the multiple of the resolution of the image to be printed with respect to the physical resolution of the ejection head may be 3, and thus the target printing speed may be determinedWherein m is meters and s is seconds.

And step 130, determining a target acceleration and deceleration distance according to the target printing speed, the maximum spray printing speed and the minimum acceleration and deceleration distance.

The target acceleration and deceleration distance may be a target acceleration and deceleration distance of the nozzle when the image to be printed is printed, so that it is easy to know that when the resolution of the image to be printed or the inherent resolution of the nozzle is changed, the determined target printing speed is correspondingly changed, and the target acceleration and deceleration distance may also be correspondingly changed.

In particular, it may be based on a formulaDetermining a target acceleration and deceleration distance, wherein S is the target acceleration and deceleration distance, V_sFor a target printing speed, S₀Is a minimum acceleration/deceleration distance, V₀The maximum jet printing speed. After the target printing speed is determined, the time taken to run the minimum acceleration/deceleration distance at the maximum printing speed may be determined according to the maximum printing speed and the minimum acceleration/deceleration distance, and further, the target acceleration/deceleration distance may be determined according to the target printing speed and the time.

In the embodiment of the invention, the minimum acceleration and deceleration distance can be S related to the performance of the spray head₀The primary determinant may be acceleration. The maximum jet printing speed can be 1.27m/s, and the time required for accelerating to the maximum jet printing speed can beThe minimum acceleration/deceleration distance may beThe target printing speed may be 0.423m/s, and the time required to accelerate to the target printing speed may beFurther, the target acceleration/deceleration distance can be determined to beIt can be seen that the determined target acceleration/deceleration distance is shorter than the minimum acceleration/deceleration, and the time taken to accelerate/decelerate is also shorter, thereby reducing the time to print one line and further increasing the printing speed.

And 140, controlling the spray head to increase the speed to the target printing speed within the target acceleration and deceleration distance, and printing the image to be printed at the target printing speed.

Specifically, the speed of the head may be raised to the target printing speed within the target acceleration/deceleration distance, and printing may be started after the speed of the head reaches the target printing speed.

In the embodiment of the invention, the image to be printed is printed at the target printing speed, the printing can be finished at one time without repeated operation, the printing time is reduced, and the target printing speed is accelerated.

In the prior art, if the resolution of a large printed image is 1800dpi and the physical resolution of the nozzle is 600dpi, the nozzle needs to go back and forth three times to print the image to be printed, and then six times of acceleration and deceleration distances need to be consumed, which easily causes waste of a printing medium. In the embodiment of the invention, only one time of printing is needed, and then only two times of target acceleration and deceleration distances are needed, so that the waste of printing media is reduced.

The printing method provided by the first embodiment of the invention comprises the following steps: determining the maximum spray printing speed and the minimum acceleration and deceleration distance of the spray head; determining a target printing speed according to the maximum spray printing speed, the physical resolution of the spray head and the resolution of the image to be printed; determining a target acceleration and deceleration distance according to the target printing speed, the maximum spray printing speed and the minimum acceleration and deceleration distance; and controlling the spray head to increase the speed to the target printing speed within the target acceleration and deceleration distance, and printing the image to be printed at the target printing speed. According to the technical scheme, after the target printing speed and the target acceleration and deceleration distance are determined, the spray head can be controlled to accelerate to the target printing speed within the target acceleration and deceleration distance, so that the image to be printed at the target printing speed is printed, the reciprocating times of the spray head on a printing medium when the high-resolution image is printed are reduced, the speed of printing the high-resolution image is increased, the target printing speed can be lower than the initial printing speed, the target acceleration and deceleration distance is also lower than the initial acceleration and deceleration distance, the target acceleration and deceleration time required for accelerating to the target printing speed can be further determined to be shortened, and the speed of printing the high-resolution image and/or characters can be further increased.
