Problems solved by technology

This algorithm consumes a lot of calculation time in the process of predicting the speed of the character car, which seriously affects the improvement of the speed of the character car, making it difficult to continue to increase the printing speed
This is obviously inconsistent with the trend of pursuing high-speed printing

Embodiment Construction

[0031] In the bidirectional printing process of wide-format inkjet printers, whenever ink droplets are ejected from the inkjet head in a direction perpendicular to the printing medium, there is a certain distance between the inkjet head and the printing medium, so the ink drops fall to the It takes a certain amount of time to print the medium; and due to inertia, the ink drop has the same horizontal speed as the character carriage when it is ejected, so the actual trajectory of the ink drop is as follows: figure 2 shown. Depend on figure 2 It can be seen that in the bidirectional printing process, due to the reciprocating motion of the character carriage, the actual landing point and the expected landing point of the ink droplets ejected at the same grid point will appear. The deviation reduces the printing quality of high-speed and high-precision inkjet printers. At the same time, the actual running curve of the word car is also as follows: image 3 As shown, there is an ...

Abstract

The invention belongs to the technical field of inkjet printing, in particular to an ink droplet droppoint deviation compensation method in bidirectional printing of an inkjet printer. The invention is characterized in that: an adaptive compensation method is realized by seven steps; deviation of ink droplets in a character wheel constant speed area can be more precisely compensated, the printing speed is greatly improved, the printing quality is improved, a problem that printing cannot be carried out in a character wheel acceleration and deceleration area is solved, and the printing efficiency is improved while the cost is saved; and the method provides technical guarantee for high-speed high-precision printing.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, in particular to a method for compensating the drop point deviation of ink droplets in the bidirectional printing of a wide-format inkjet printer, which is used for compensating the vibration caused by the lateral movement of the character carriage and the speed of the character carriage during the printing process The deviation of the ink drop point caused by it can increase the printing speed and improve the printing quality. Background technique [0002] Inkjet printers form text or images by ejecting ink droplets onto print media. The serial inkjet printer technology is widely used in inkjet printers and plotters, and it is realized by controlling the horizontal scanning of the inkjet head and the longitudinal feeding of the printing medium. During the entire printing process of the inkjet printer, the nozzles scan along a direction parallel to the printing medium, while ink droplets...
