As an alternative, the determination of the position of the individual print units of the print head is carried out by first determining the position of the print head using digital measurements.
As an optional embodiment, the coordinate system is a rectangular plane coordinate system xoy, and each inkjet printing unit is coordinated in the established coordinate system as: two different points A, B are taken on the jet printing unit and the coordinates of the two points are recorded separately.
As an optional embodiment, the controlling and adjusting the overlapped inkjet printing units includes: and digitally controlling and adjusting the overlapped parts of the plurality of jet printing units to enable the overlapped parts to be 0.

and the control and adjustment unit is used for controlling and adjusting the overlapped jet printing units.
As an alternative embodiment, the position determination unit determines the position of each jet printing unit of the print head by means of digital measurement.
As an optional implementation manner, the coordinate system is a rectangular plane coordinate system xoy, then the mounted inkjet printing unit is subjected to inkjet printing of a first calibration pattern, and the number of the inkjet printing units to be adjusted in the X or Y direction is determined according to different positions of the inkjet printing unit on the calibration pattern. The position coordinating unit realizes the coordination of the jet printing unit by taking two different points A, B on the jet printing unit and recording the positions of the two points in a coordinate system. When the plurality of jet printing units of the printing head are installed, the installation is carried out according to a machined installation groove, and the installation groove is not reserved with debugging tolerance, so after the installation, patterns sprayed among the plurality of units are determined to have an overlapped part (or need to be adjusted to be overlapped), wherein the overlapped part is magnified and is seen as the overlapped part of each micro unit in the X or Y direction of the xoy coordinate system, and the overlapped part in the X direction is shown in the figure 2, the table 1 and the table 2, for example, the jet printing units X2 and X3 are intercepted, and is magnified and seen as a single control micro unit (the upper part is X2, the lower part is X3, and the number is the micro unit number for controlling whether to be displayed or not). The coordinate of each jet printing unit and the dot taking are established here for the convenience of determining the position of the jet printing unit and the overlapped microcell part of each jet printing unit.
As an optional embodiment, the control and adjustment unit performs digital adjustment and control on the overlapped part of the plurality of jet printing units to make the overlapped part 0, so as to realize digital control and adjustment of the jet printing units. During the specific adjustment, the jet printing unit is fixed and is driven by the conveying roller to move, or the paper is fixed and is driven by the trolley to move back and forth perpendicular to the paper feeding direction.
As an optional implementation, the terminal device includes:

The specific adjustment process is as follows:
adjustment mode 1:
the number of the jet printing units in the paper in the figure 2 is only 3, and the number of the jet printing units in practical application can be more. The outlet direction of the jet printing unit is vertical to the cloth moving direction, and in the mode, the jet printing unit is fixed, and only paper can move in the vertical direction. As shown in table 1 below:
s41: for the superposition in the X direction, taking the cutting jet printing units X2 and X3 as an example, the superposition is magnified to a single control micro unit (the upper surface is X2, the lower surface is X3, and the number is the micro unit serial number for controlling whether to display or not):
TABLE 1
As seen from table 1, when 2 microcells of X2 and X3 are duplicated, it is only necessary to control the last 2 microcells (255 and 256) of X2 or the first two microcells (1 and 2) of X3 to be absent by controlling the storage device to be indirect by the terminal device, and to sequentially shift the other data by 2 microcell units to achieve disappearance of the image overlap and continuation of the remaining image.
S42: for the coincidence in the Y direction, the data of X2 can be sent to it in advance by the terminal device controlling the storage device indirectly according to the delay of the drawing time, i.e. the data can coincide with the previous patterns of X1 and X3.
The adjusting mode 2 is as follows:
in this manner, the inkjet printing unit reciprocates perpendicularly to the paper feeding direction, and prints a pattern onto the paper once during the movement, as shown in table 2 below:
s41: for the superposition in the X direction, if the moving trolley moves towards the left, the pattern of the X2 comes before the pattern of the X1, at this time, the number of the patterns can be sent to the X2 before a period of time, the data of the X1 is sent out in a delayed mode, and the patterns of the X1 and the X2 can be superposed
S42: for the coincidence of the Y direction, taking the X2 and X1 as an example, and enlarging to a single control micro-cell to see (X2 on the left, X1 on the right, the number is the micro-cell number for controlling whether to display):
TABLE 2
As seen from table 2, 3 microcells of X2 and X1 are duplicated, and in this case, the disappearance of image overlap and the continuation of the remaining images can be achieved by controlling the last 3 microcells (254, 255 and 256) of X2 or the first 3 microcells (1, 2 and 3) of X1 to be absent only by controlling the storage device to be switched by the terminal device, and sequentially shifting the other data by 3 microcell units.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and all such changes or substitutions are included in the scope of the present invention.
