Embodiment 1

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a data processing method, which specifically includes the following steps:

[0031] Step S101: Splitting one line of image dot matrix data into n groups of image dot matrix data according to the preset nozzle arrangement rule.

[0032] Wherein, the above-mentioned one-line image lattice data is one line in the received multi-line image lattice data. All nozzles in the preset nozzle arrangement rule are divided into multiple virtual rows, and n is the number of the multiple virtual rows included. That is to say, all the nozzles are divided into n virtual rows according to the preset nozzle arrangement rule, and one line of image dot matrix data is divided into n groups of image dot matrix data according to the n virtual rows.

[0033] Such as figure 2 As shown, in this embodiment, the nozzles are divided into 4 virtual rows as an example. The 4 virtual rows are respectively represented by sol...

Embodiment 2

[0041] The first embodiment above briefly introduces the data processing method of the present invention, and it will be further described below based on the first embodiment and specific application scenarios.

[0042] Specifically, such as image 3 As shown, step S101 includes the following steps:

[0043] Step S301: Divide all nozzles into n virtual rows according to the arrangement rules of all nozzles in X direction and Y direction.

[0044] Among them, the X direction is the direction perpendicular to the paper-feeding direction, and the Y-direction is the paper-feeding direction. The rules of all nozzles in the X and Y directions are analyzed, and all nozzles are divided into n virtual rows. The number and pattern of nozzles are the same. Different nozzles in the same virtual row have different coordinate values ​​in the Y direction, and corresponding nozzles in different virtual rows have the same difference in Y-direction coordinate values. Each virtual row includes...

Embodiment 3

[0080] The above first and second embodiments respectively introduce the data processing method of the present invention from different application scenarios, and the following third embodiment will further introduce its corresponding device in conjunction with the accompanying drawings.

[0081] Specifically, such as Figure 7 As shown, the data processing device specifically includes:

[0082] The splitting module 71 is used to split a line of image dot matrix data into n groups of image dot matrix data according to the preset nozzle arrangement rule; wherein, all nozzles in the preset nozzle arrangement rule are divided into multiple virtual rows, n is the row number of the plurality of virtual rows included;

[0083] The first processing module 72 is used to write n groups of image dot matrix data into the external memory according to the first preset address rule;

[0084] The second processing module 73 is used to read out n sets of image dot matrix data according to t...

Abstract

The invention discloses a data processing method and device and an ink-jet printer. The data processing method comprises the steps that a thread of image dot matrix data are split into n groups of image dot matrix data according to a preset nozzle arrangement rule, wherein in the preset nozzle arrangement rule, all nozzles are divided into multiple virtual rows, and n represents the row number of the virtual rows; n groups of the image dot matrix data are written into an external storage according to a first preset address rule; n groups of the image dot matrix data are read out according to the address sequence of the external storage and then written into an internal storage according to a second preset address rule; and n groups of the image dot matrix data are read out according to the address sequence of the internal storage and then sent to the nozzles. According to the data processing method, the external storage and the internal storage are cooperatively used, the characteristics that the external storage is large in data storage volume, and the internal storage is high in data reading operation processing speed are fully utilized, and then the image dot matrix data splitting delaying processing speed is increased.

Description

technical field [0001] The invention relates to the technical field of computer printing applications, in particular to a data processing method, device and inkjet printing machine. Background technique [0002] With the development of inkjet printing technology, the market has put forward higher requirements for the accuracy of inkjet printing, which requires nozzle manufacturers to continuously improve the printing accuracy of nozzles. The printing accuracy can be measured by DPI (Dots Per Inch, the number of nozzles per inch ) to describe. Due to the limitation of the nozzle processing technology, the distance between the nozzles cannot be too small. Therefore, many nozzle manufacturers use multiple rows of nozzles for splicing, so that the DPI of the projection perpendicular to the paper feeding direction increases, thereby improving the printing accuracy. However, this splicing method also brings a lot of problems to data processing. It is necessary to split and delay ...
