Embodiment 1

[0054] see figure 2 , the invention provides an inkjet printing method, comprising the steps of:

[0055] S1. Convert the image to be printed into an image matrix, divide the image matrix into several sub-image matrices of equal size, select one of the sub-image matrices as the first image matrix required for this printing, and the height of the sub-image matrix The value is equal to the number of each group of nozzle holes on the printer nozzle; in this embodiment, each group of nozzle holes on the printer nozzle includes several rows of nozzle holes, and several rows of nozzle holes are arranged in a staggered manner. The printed image is obtained by processing the halftone algorithm. The halftone algorithm is a common technology in the printing field. The halftone algorithm processing here can be implemented by methods in the prior art. The width of the first image matrix is ​​equal to the width of the image matrix, assuming that the image matrix is ​​C xy , the first im...

Embodiment 2

[0094] see Figure 14 , the present invention also provides an inkjet printing device, comprising:

[0095] The image matrix generation module 1 is used to convert the image to be printed into an image matrix, divide the image matrix into several sub-image matrices of equal size, and select one of the sub-image matrices as the first image matrix required for this printing, so The height value of the sub-image matrix is ​​equal to the number of each group of nozzle holes on the printer nozzle.

[0096] Image matrix transformation module 2, used to set the number of feathering points, divide the first image matrix into 3 image matrix units according to the number of feathering points, including the first image matrix unit, the second image matrix unit and the third image matrix unit ; The height sum of the first image matrix unit, the second image matrix unit and the third image matrix unit is equal to the height of the first image matrix, and the first image matrix unit and th...

Embodiment 3

[0120] The present invention also provides an inkjet printing device, comprising: a memory, a processor, and a computer program stored on the memory and operable on the processor, when the computer program is executed by the processor, the following step:

[0121] S1. Convert the image to be printed into an image matrix, divide the image matrix into several sub-image matrices of equal size, select one of the sub-image matrices as the first image matrix required for this printing, and the height of the sub-image matrix The value is equal to the number of each group of orifices on the printer nozzle.

[0122] S2. Set the number of feathering points, divide the first image matrix into 3 image matrix units according to the number of feathering points, including the first image matrix unit, the second image matrix unit and the third image matrix unit; the first image The height sum of the matrix unit, the second image matrix unit and the third image matrix unit is equal to the hei...

Abstract

The invention discloses aninkjet printing method, inkjet printing device, and inkjet printing apparatus. An image to be printed is converted into a plurality of sub-image matrices of equal size, based on the eclosion points set, a sub-image matrix is divide into three image matrix units, the first image matrix unit of the three image matrix units are combined with the mask image matrix to generate a second image matrix, the third image matrix unit and the complementary mask image matrix are combined to generate a third image matrix, so as to diffuse an error caused by the printing accuracy ofthe ink jet printing apparatus and the driving motor from an element in the first image matrix to each element in the sub-image matrix, and outputthe data of the plurality of the fourth image matrices to further spread the distance error of the two paper feeds onto the plurality of the fourth image matrices, thereby effectively solving the problem of overlapping or blank spacing of the printed images, and further ensuring the quality and quality of the printed images.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printing method, an inkjet printing device and an inkjet printing device. Background technique [0002] There are two main printing methods used by inkjet printers: continuous inkjet printing method and random inkjet printing method. Early inkjet printers and current large-format inkjet printers all use continuous inkjet printing methods, while the current popular inkjet printers generally use random inkjet printing methods. The continuous inkjet printing method is represented by the charge modulation type. In the random inkjet system, the ink is only ejected when printing is required, so it is also called on-demand. [0003] Such as figure 1 As shown, whether it is a continuous inkjet printing method or a random inkjet printing method, due to the printing accuracy of the inkjet printing device and the error of the drive motor, it is difficult to ensure that t...
