Embodiment 1

[0053] figure 2 Shows a flow chart of a method for obtaining an inkjet error according to an embodiment of the present invention, the method can be used but not limited to Figure 1B The inkjet printing device shown is used to detect the inkjet error of the nozzle. Such as figure 2 As shown, the method includes the following steps:

[0054] Step S101, acquiring the lifting height of a predetermined position on the object to be printed.

[0055] In this example, when the method is used for Figure 1B The inkjet printing device shown can be obtained based on Figure 1B The lifting height shown in is obtained from the height measurement result fed back by the device, and the lifting height at a predetermined position on the object to be printed is calculated. Of course, this method is not limited to Figure 1B Shown ink-jet printing device, for example, also can be by above the predetermined position on the object to be printed, and be positioned at the position of the sa...

Embodiment 2

[0075] Figure 4 Shows a flow chart of an inkjet correction method according to an embodiment of the present invention, which can be used but not limited to Figure 1B The inkjet printing device is used to assist in correcting the inkjet position error of the nozzle. Such as Figure 4 As shown, the method includes the following steps:

[0076] S301. Obtain the lifting height of a predetermined position on the object to be printed. Here, the specific calculation method of the lift-up height at the predetermined position can be understood with reference to Embodiment 1, and will not be repeated here.

[0077] S302. Obtain a theoretical vertical deviation between the ink output position of the nozzle and the predetermined position on the object to be printed. Here, the vertical deviation refers to the deviation in the vertical direction, and the theoretical vertical deviation refers to the distance between the object to be printed and the nozzle in the vertical direction when...

Embodiment 3

[0087] Figure 5 A functional block diagram of an inkjet error acquisition device according to an embodiment of the present invention is shown, and the device can be used to implement the inkjet error acquisition method described in Embodiment 1 or any optional implementation manner thereof. Such as Figure 5 As shown, the device includes: a lift height acquisition module 10 and an inkjet position error calculation module 20 .

[0088] The lifting height obtaining module 10 is used to obtain the lifting height of a predetermined position on the object to be printed.

[0089] The inkjet position error calculation module 20 is used to obtain the inkjet position error at the predetermined position according to the lift height of the predetermined position.

[0090] As an optional implementation of the embodiment of the present invention, the calculation module 20 of the error calculation module may include: a first error calculation unit 21 and an inkjet position error calculat...

Abstract

Disclosed are an inkjet error acquisition and inkjet correction method, a device, and an inkjet printing device. The inkjet error acquisition method comprises: acquiring a warping height of a preset position on an object to be printed (1), and acquiring an inkjet position error of the preset position according to the warping height of the preset position. By an influence factor affecting the printing precision of the inkjet printing device, that is, the warping height of the object to be printed, the printing error calculation method based on the influence factor is provided, the problem that, when the warping problem of the object to be printed is not considered in the prior art, after compensation and correction are carried out according to error caused by other known influence factors, a relatively large deviation still exists between the position of ink sprayed by the inkjet printing device on printed matter and the preset position, so that the quality of the printed matter is poor, is solved.

Description

technical field [0001] The invention relates to the field of inkjet technology, in particular to methods and devices for obtaining and correcting inkjet errors and an inkjet device. Background technique [0002] Inkjet technology is not only used in traditional printers, but also widely used in PCB (full English name: Printed Circuit Board, Chinese: printed circuit board), and is also expected to be applied to organic light-emitting electronic boards (English: Organic Electro-Luminescence, referred to as: In the manufacturing process of electronic devices such as OEL, organic EL), and liquid crystal panels. [0003] In an inkjet device, there is a great relationship between ink landing position deviation during printing and the quality of printed matter. The deviation of the landing position is affected by many factors, such as: the position deviation of the printing object, the ink ejection position of the nozzle, the ink droplet ejection angle of the nozzle, the horizonta...
