CIJ inkjet printer printing speed control method

Abstract

The invention discloses a CIJ ink-jet printing machine speed control method. The method comprises that a printing speed value is inputted into an upper computer, a speed conversion module converts the printing speed value to a total amount of ink droplets needed for printing a column of a dot matrix, an integration module obtains a first non-printing ink droplet numerical value which is needed to be inserted between two printing ink droplets in the same column of the dot matrix according to the total amount of the ink droplets, a complementation module obtains a second non-printing ink droplet numerical value which is needed to be inserted between the two columns of the dot matrixes according to the total amount of ink droplets, a determination device determines whether the non-printing ink droplet is needed to be inserted between the two printing ink droplets and the two columns of the dot matrixes according to the first non-printing ink droplet numerical value and the second non-printing ink droplet value, an ink-jet encoding system transmits an ink droplet encoding signal to a charging electrode according to the determination result of the determination device, and the charging electrode charges the corresponding printing ink droplet according to the ink droplet encoding signal. The IG ink-jet printing machine speed control method improves the printing quality through automatically adjusting the utilization rate of the ink droplets and automatically distributing the interval positions of the ink droplets.

Description

technical field [0001] The invention relates to the technical field of industrial inkjet printers, in particular to a method for controlling the printing speed of a CIJ inkjet printer. Background technique [0002] The inkjet printer is a device that is controlled by software and uses a non-contact method to mark on the product. It is mainly composed of an inkjet coding system and an ink circuit system. Among them, the electric field deflection continuous inkjet printer uses charged ink dots The deflection in the electric field is used to realize the reduction of characters, which is usually referred to as CIJ inkjet printer for short. [0003] The working principle of the CIJ inkjet printer is: in the ink system, the ink is ejected from the nozzle under the pressure of the pressure pump. When the ink passes through the nozzle, it is broken into a series of continuous and equal spacing by the piezoelectric crystal. And the ink drops of the same size form an ink drop flow. W...

Problems solved by technology

It can be seen that in the traditional printing speed control method, the arrangement and selection rules of printing ink droplets and non-printing ink droplets are fixed, resulting in a fixed printing speed, which cannot be adjusted to a more suitable ink droplet utilization rate according to the actual graphic information. It is not set on an optimal ink dot utilization, but generally speaking, the lower the ink drop utilization, the lower the printing quality, the better. Therefore, this method cannot best distribute the interval between printing ink drops. Failure to prioritize enough non-printing ink droplets between two charged ink droplets, resulting in poor print quality
