Description
Technical Field
The invention relates to the technical field of printing, in particular to a high-precision digital printing nozzle.
Background
The printing core of an ink jet printer is called the ink head or print head, or nozzle. The ink jet head has a plurality of very small orifices, called orifices, through which ink is ejected at high velocity during printing to form an image on a print medium. The number of orifices directly determines the effectiveness and speed of the printing. Besides the higher printing resolution can be obtained if the number of the jet holes is enough, the representation of some details of the printing object, such as human hair, can be more sufficient.
When an inkjet printer uses a plurality of nozzles to print a color in a combined manner, a common combined arrangement method in the prior art refers to fig. 1, but when the printing process of the arrangement mode needs to reach 1200DPI, the coverage is often performed through 2pass, but the step precision problem exists in the arrangement mode, the real physical precision of 1200DPI cannot be achieved, and in the process of printing a pure color, the time difference of first spraying and then spraying exists in the spliced part, so that the splicing position has slight difference, and the attractiveness and the printing quality are affected.
There is therefore a need to propose a solution to this problem.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a high-precision digital printing nozzle, which can improve the printing precision by additionally inserting through arranging a first straight line and a second straight line which are distributed in a staggered manner, and a first straight line module and a second straight line module, reduce the color difference generated during printing through the complementation of splicing parts, and improve the printing efficiency and quality.
The technical purpose of the invention is realized by the following technical scheme: the utility model provides a shower nozzle is printed to high accuracy digital printing, includes shower nozzle board and a plurality of shower nozzle combination of setting on the shower nozzle board, the shower nozzle combination is including first in line and the second in line, first in line staggers the distribution with the second in line, first in line and the second in line all include a plurality of spray group modules that are located same straight line, spray group module including four groups of nozzles, four groups two liang of vertical arrangement respectively of nozzle are to stagger straight line module one and straight line module two that distributes, the nozzle is including a plurality of thin shower nozzles.
By adopting the technical scheme, in the process of fine spray head ink jet printing, because the first straight line and the second straight line are staggered and distributed, and the first straight line module and the second straight line module which are formed by the nozzles in the spray group module are also staggered and distributed, when in printing, the fine spray head on the first straight line can be just inserted with the fine spray head on the second straight line, after the two fine spray heads of 600DPI are complementarily inserted, only 1pass needs to be printed, 1200DPI can be perfectly reached, two times of repeated printing is not needed, the printing efficiency and precision are improved, and when in printing pure color, the chromatic aberration caused by repeated ink jet can be reduced by the mode of inserting, the quality of printing ink jet is improved, in the printing process, the nozzles on the first straight line module and the second straight line module are staggered and distributed due to two staggered distribution, a certain staggered splicing part exists, and the first straight line and the second straight line are staggered and distributed, therefore, the splicing parts of the first straight line module and the second straight line module on the first straight line can just correspond to the position of the un-spliced part of the first straight line module on the second straight line, and when printing is carried out, the un-spliced part on the second straight line can cover the splicing part on the first straight line, so that the color difference generated in the printing process at the splicing position is reduced.
The invention is further configured to: and the distance between the nozzles in the same vertical column on the first linear module and the second linear module is less than the length of the nozzles.
The invention is further configured to: the spraying module at least comprises four groups.
The invention is further configured to: the nozzle at least comprises four fine spray heads.
Through adopting above-mentioned technical scheme, the vertical difference in height between first inline and the second inline is 200 holes.
The invention is further configured to: the height difference can enable the nozzles on the first straight row and the second straight row to be just offset and complementary.
In conclusion, the invention has the following beneficial effects:
through setting up first in line and the second in line that the dislocation distributes to and sharp module one and sharp module two, can improve the printing precision through interpolation when printing, and reduce the colour difference that produces when printing through the complementation to the concatenation position, improved printing efficiency and quality
