Problems solved by technology

In order to accomplish the above tasks, the commonly used nozzle arrangement method is the oblique arrangement method. Since the images are all horizontal rectangular squares, the print data must be rearranged according to the inclination angle of the nozzles. The workload is heavy and the efficiency is low. At the same time, it is difficult to guarantee the printing quality. Consistency

Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Fig. 1 shows a schematic diagram of a method for vertically arranging four nozzles according to an embodiment of the present invention.

[0027] For the convenience of description and understanding, it is assumed that each nozzle has six nozzle holes, that is, N=3, 2N=6. Nozzle 1 is for spraying black ink, Nozzle 2 is for cyan ink, Nozzle 3 is for magenta ink, Nozzle 4 is for yellow ink. Arrange in the order of cyan and black, the first nozzle hole of each nozzle faces down, and the nozzle holes are represented as a, b, c, d, e, f from top to bottom. The distance between two nozzle holes is d, and the distance between two adjacent nozzles is 4d, which is the distance between 4 nozzle holes.

[0028] It can be seen from Fig. 1 that the horizontal position of nozzle a of nozzle 3 is aligned with the middle of nozzle c a...

Abstract

A vertical arranging method for the nozzles of color ink-jet plotter is characterized by that 4 nozzles for yellow ink, pinkish red ink, green ink and black ink are sequentially arranged in vertical direction. Each nozzle has 2N jet pinholes, where N-32-256. The position of the nozzle for yellow ink is used as the horizontal reference. The horizontal position of the first jet pinhole of next nozzle is between N and N+1 pinholes of previous nozzle. Its advantages are high print precision in X and Y directions and high printing efficiency.

Description

Technical field: [0001] The invention relates to a method for vertically arranging the nozzles of a color inkjet printer, which uses digital control technology to realize two complete coverage printings of the nozzles of the color inkjet printer in the vertical arrangement, improves printing efficiency and printing accuracy, and belongs to the technical field of printer control. Background technique: [0002] Assuming that the color inkjet printer has four nozzles of the same type, each nozzle is supplied with ink of four colors: yellow, cyan, black, and magenta. The printing process is as follows: First, a color image is decomposed into grids in the computer according to a certain resolution, and each grid corresponds to a point on the image. In addition to the corresponding position information, the point also requires the above corresponding The four color information of . Then the computer sends the position and color data of the image to the inkjet control circuit. By ...
