Problems solved by technology

[0005] However, the printing principle of CIJ inkjet printers determines that the higher the printing resolution, the more serious the interference between ink dots, the easier it is to cause the decline of printing neatness, and it is also easy to cause ink dots to fly to the surroundings of the printed content and affect the appearance. Therefore, in the case of printing space, the distance between columns can be appropriately widened to reduce the mutual interference between ink dots. However,

Example Embodiment

[0031] Such as figure 1 As shown, the variable speed printing control algorithm of CIJ inkjet printer disclosed in the present invention includes:

[0032] For a piece of jet printing data, set the initial printing speed, which can make the jet printing data clearly printed; if there are data that require different horizontal resolutions in the piece of jet printing data (the judgment process is determined by the printing operator It can be obtained by directly observing the print content), then the print data is divided into a modified speed area and a constant speed area. For the print data in the modified speed area, the printing ink droplet and the printing ink droplet in the printing array Insert more non-printing ink droplets than the speed-constant area to increase the interval between printing ink dots to reduce the printing speed of the modified speed area.

[0033] The process of reducing the printing speed of the modified speed area is specifically as follows:

[0034] St...

Abstract

The variable-speed printing control algorithm of CIJ inkjet printer disclosed by the present invention includes: first setting the initial printing speed for a piece of printing data, and the initial printing speed can make the printing data clearly printed; If the data with different horizontal resolutions is required, the printing data is divided into the modified speed area and the constant speed area. For the printing data in the modified speed area, by inserting the corresponding printing ink drop between the printing ink drop and the printing ink drop Increase the spacing between printed ink dots by increasing the spacing between printed ink dots by more non-printing ink drops than in the speed constant area to reduce the printing speed in the modified speed area. The invention can effectively reduce the interference between ink dots in the high-resolution printing information and reduce the scattered ink around the information, improve the neatness and aesthetics of the printing content, and realize the best printing effect.

Description

technical field [0001] The invention relates to the technical field of industrial inkjet printers, in particular to a variable-speed printing control algorithm for CIJ inkjet printers. Background technique [0002] The inkjet printer involved in the present invention is an electric field deflection continuous inkjet printer, which uses the deflection of charged ink dots in an electric field to restore characters, and is usually referred to as a CIJ inkjet printer. The working principle of the CIJ inkjet printer is: the ink forms pressure ink in the spray gun seat under the action of the pressure pump, and is sprayed out through the small hole at the front end of the spray gun seat, that is, the nozzle. When the ink passes through the nozzle, it is broken into a piece by the piezoelectric crystal. A series of ink droplets (also known as ink dots) with equal spacing and the same size. When the jet ink flow continues to move downward and pass through the charging electrode, the...
