Problems solved by technology

However, in this method, the distance between the two nozzles spraying magenta ink is too far. No matter which nozzle the ink cartridge is close to, it is difficult to ensure the verticality of the ink tube of the other nozzle. It will cause the ink pressure of the nozzle to be unstable and affect the ink supply

Embodiment Construction

[0020] Such as Figure 3b As shown, the method for arranging the ink nozzles of different colors of the color inkjet printer of the present invention, the specific steps are that the inkjet printer is provided with four nozzles, and each nozzle corresponds to a primary color ink, including C (cyan), M (magenta) , Y (yellow), K (black) inks, the four nozzles are arranged in two rows along the printing medium feeding direction, the colors of the inks in the two nozzles in the front row are K (black) and C (cyan), respectively, and the nozzles in the rear row The colors of the medium inks are M (magenta) and Y (yellow). Such as Figure 3c As shown, in the nth going trip of the nozzle trolley, M (magenta) and Y (yellow) will be covered at one position on the printing medium first, and one position on the printing medium will be covered first during the nth return trip Y (yellow) and M (magenta); after stepping, in the n+rth trip of the printhead trolley, cover K (black) and C (c...

Abstract

The invention discloses a method for arranging ink nozzles with different colors of a color inkjet printer. In particular, the method comprises: a cyan ink nozzle and a magenta ink nozzle and a cyan ink nozzle and a yellow ink nozzle of the printer are arranged along the feeding direction of print medium, and when the printer works, along with step feed of the print medium, the cyan ink and the magenta ink and the cyan ink and the yellow ink can be sprayed on the print medium respectively according to a fixed order. In the method, because the cyan ink nozzle, the magenta ink nozzle and the yellow ink nozzle are orderly arranged along the feeding direction of the print medium, the cyan ink and the magenta ink and the cyan ink and the yellow ink sprayed by the inkjet device are always sprayed on the print medium according to the fixed order regardless of left print and right print of the printer, thereby solving the problem existing in the prior printer that the hue of the same color is different in the bi-directional printing and ensuring the printing quality of the printer.

Description

technical field [0001] The invention relates to a method for arranging ink nozzles of different colors in a color inkjet printer. Background technique [0002] Color inkjet printers are equipped with primary color inks, including C (cyan), M (magenta), Y (yellow), K (black) and other four basic primary color inks and several other primary color inks derived from them. The combined superposition of different proportions of ink can simulate thousands of colors that exist in reality. For the same color, because the order of different primary color inks covering the printing medium is different, different tones of colors will appear, resulting in the appearance of dark and light colored banded stripes. For example, printing pure blue needs to be obtained by superimposing C (cyan) ink and M (magenta) ink. If C (cyan) ink is covered on M (magenta) ink, it will appear as blue with a strong magenta tone after superposition; If the M (magenta) ink is covered on the C (cyan) ink, it...
