Problems solved by technology

Due to the limitations of processing technology and inkjet technology, it is often impossible to shrink the nozzle holes infinitely, and the number of nozzle holes per unit area cannot be increased infinitely, which restricts the improvement of printing accuracy.
[0004] Although there are currently some cutting-edge technologies for improved nozzles that can achieve higher-precision printing, these technologies are in the hands of a few people, and there is an exponential growth relationship between the cost increase of these improved nozzles compared with ordinary nozzles and the improvement of printing accuracy. Difficult to be widely used

Embodiment 1

[0029] A method for improving the accuracy of horizontal printing, using two rows of nozzles 110 arranged side by side along the lateral direction of the printer to print the same ink, and making the printing starting points between the two rows of nozzles 110 staggered by 1 / 2 of the first unit W1 , the first unit W1 is the center-to-center distance between two adjacent nozzle holes 111 of the nozzle head 110 in the lateral direction of the printer. In this embodiment, two rows of nozzles 110 arranged side by side along the lateral direction of the printer are used to print the same ink. The printing starting points between the two rows of nozzles 110 are staggered by 1 / 2 of the first unit W1, and the printing accuracy can be increased to twice the original. The method is simple and effective, and there is no need to improve the original nozzles 110 or replace them. The cost is not only the higher precision nozzle 110 which is twice the cost of the original nozzle 110, it is eco...

Embodiment 2

[0032] As an improvement to the above-mentioned method embodiment, in this embodiment, two printing units 200 arranged in the lateral direction of the printer are used to print the same ink, and the two printing units 200 are staggered by 1 / 2 in the longitudinal direction of the printer. A second unit W2, the second unit W2 is the center distance between two adjacent nozzles 110 in any row of nozzles 110 in the longitudinal direction of the printer. Each of the printing units 200 includes two rows of nozzles 110 arranged in the transverse direction of the printer, and the two rows of nozzles 110 are staggered by 1 / 2 of the first unit W1 in the longitudinal direction of the printer. The first unit W1 is the center distance between two adjacent nozzle holes 111 of the nozzle 110 in the longitudinal direction of the printer.

[0033] The nozzle 110 is a high-precision component, which means that its price is relatively expensive. As we all know, in industrial printing, the format...

Embodiment 3

[0036] As an improvement to the above-mentioned method embodiment, this embodiment uses two rows of nozzles 110 or two printing units 200 of the same printing module on the printer to print the same ink, that is, two rows of nozzles 110 that print the same ink or two rows of nozzles that print the same ink The printing unit 200 is uniformly arranged on the same printing module, which can better and more easily ensure the positional accuracy between the nozzles 110 and 110 and between the printing unit 200 and the printing unit 200, reduce assembly difficulty, and improve assembly efficiency.

[0037] Device Example 1

[0038] A printer applying the above-mentioned method for improving lateral printing accuracy, comprising a conveying platform for conveying printing media and a printing system located above the conveying platform, said printing system comprising several printing units 200 arranged along the lateral direction of the printer, said The printing unit 200 includes t...

Abstract

The invention relates to the field of industrial printing, and discloses a method for improving lateral printing accuracy. N columns of nozzles arranged side by side along the lateral direction of theprinter are applied to print the same ink, and the printing starting points between the N columns of nozzles are staggered by 1 / N first unit, wherein the first unit is the center distance between thetwo adjacent nozzle holes of the nozzles in the lateral direction of the printer. The invention also discloses the printer using the method for improving the lateral printing accuracy. The printer comprises a transport platform for transporting printing media and a printing system located above the transport platform. The printing system comprises multiple printing units arranged along the lateral direction of the printer. The printing units include N columns of nozzles arranged side by side along the lateral direction of the printer to print the same ink, the printing starting points betweenthe N columns of nozzles are staggered by 1 / N first unit and the first unit is the center distance between the two adjacent nozzle holes of the nozzles in the lateral direction of the printer.

Description

technical field [0001] This patent relates to the field of industrial printing, more specifically, to a method for improving horizontal printing accuracy and its printer. Background technique [0002] Industrial printers are used to print on large-sized media such as ceramic tiles, wood boards, glass, corrugated paper, and buckle boards. By inkjet, various colors of ink are sprayed on the print media and then further processed to obtain the expected pattern. During the printing process, the ink penetrates into the interior of the printing medium through corrosion, so that the pattern obtained by inkjet printing is not easy to fade, and has the characteristics of waterproof, anti-ultraviolet, and anti-scratch. [0003] The ink ejected from the nozzle of the printer falls on the surface of the printing medium to form ink dots one by one. These ink dots together form the target pattern of printing. The size of the ink dots and the number of ink dots per unit area are directly r...
