The inkjet printing method provided by the application can be applied to an application environment as shown in fig. 1, wherein the inkjet control terminal 102 communicates with the inkjet printing device 104 through a network, wherein the inkjet control terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the inkjet printing device 104 is used for manufacturing O L ED devices.
For example, a Hole injection layer (Hole Inject L eye, HI L), a Hole transport layer (Hole transport L eye, HT L), a light Emitting layer (Emitting Material L eye, EM L) and the like on the O L ED device, and pixel pits of the Hole injection layer, the Hole transport layer and the light Emitting layer can be filled with functional Material ink by means of inkjet printing, wherein the pixel pits have a certain ink capacity, and a target total volume of ink droplets needs to be set for the ink capacity in inkjet printing, that is, after a plurality of ink droplets are dropped into the pixel pits, the sum of the volumes of the ink droplets needs to be matched with the target total volume of the ink droplets.
In order to facilitate understanding of the present application by those skilled in the art, an inkjet printing apparatus according to an embodiment of the present application will be described below with reference to fig. 2 and 3.
Fig. 2 is a schematic diagram of an inkjet printhead for making O L ED devices, from which it can be seen that an inkjet printhead 202 prints functional material ink 206 onto pixel wells 204 of an O L ED device.
As can be seen from the figure, the inkjet printhead 302 is inkjet printing on the O L ED device 304, the bottom plane of the inkjet printhead 302 is parallel to the plane of the O L ED device 304, the inkjet printhead 302 can move in the X and Z directions, and the O L ED device 304 can move in the Y direction.

After receiving the target ink jetting angle, the ink jetting device 104 can adjust the ink jetting angle of the ink jetting print head to the target ink jetting angle through the angle adjusting device, so that when a printing task is executed, the ink jetting print head is adjusted according to the target ink jetting angle in one ink jetting stroke, more nozzles are aligned with pixel pits and participate in ink jetting, and the number of times of the ink jetting stroke is reduced.
By the ink-jet printing method, the target ink-jet angle is determined in the plurality of ink-jet angles, so that when the ink-jet printing equipment executes a printing task, more nozzles can participate in ink-jet in one ink-jet stroke, the number of ink-jet strokes required by the printing task is reduced, the interval time between the initial stage and the final stage of ink-jet printing is shortened, the problem of uneven film thickness of an O L ED device film caused by inconsistent drying degree is avoided, and the performance of an O L ED device is improved.

a substep S13 of calculating a product of a plane distance value of the serial number of the nozzle to be processed and a cosine value of the one ink ejection angle to obtain a lateral distance value;
a substep S14, matching the lateral distance value with a plurality of preset target lateral distance values, and determining the serial number of the nozzle to be processed as a participating nozzle serial number when the lateral distance value is the same as any one target lateral distance value;
and a substep S15 of counting the number of participating nozzle numbers to obtain the number of participating nozzles at the one ink ejection angle.

In the above-described sub-step S12, specifically, the plane distance value may be acquired for the serial number of the nozzle to be processed, and one of the cosine values of the ink ejection angle may be calculated from among a plurality of ink ejection angles. For example, the ink ejection angle Θ is calculatednThe cosine of the ink ejection angle cos30 ° is 0.866, 30 °.
In the above substep S13, the planar distance value S of the nozzle number to be processed and the cosine value cos Θ DEG of the ink ejection angle can be calculatednThe product of (a) and (b) to obtain a lateral distance value. On the basis of the above example, the lateral distance value Sx＝5*0.866＝4.33mm。

If the lateral distance value matches a target lateral distance value, the nozzle corresponding to the nozzle number to be processed may be determined to be aligned with a pixel pit of the O L ED device and to be involved in ink ejection when executing a print job.
In the above sub-step S15, specifically, after determining the plurality of participating nozzle numbers, the number of the plurality of participating nozzle numbers may be counted as the number of participating nozzles of one ink ejection angle.
