High-voltage power supply in the application of electric jet printing

With the continuous advancement of technology, printing technology is also constantly developing. Among them, electric jet printing technology, as a new printing technology, has been widely used in various fields, such as advertising, packaging, textiles, etc., due to its high efficiency, environmental protection, and low cost. High-voltage power supply, as one of the core components of electric jet printing equipment, directly affects the quality and effect of electric jet printing. This article will introduce the application of high-voltage power supply in electric jet printing from a professional perspective.

I. Overview of electric jet printing technology

Electric jet printing technology is a printing technology that sprays ink onto the substrate through an electronic nozzle. Its basic principle is to use the high voltage generated by the high-voltage power supply to charge the ink, and then spray the ink out of the nozzle under the force of the electric field, forming ink droplets. During the flight of the ink droplets, the position and jet printing of the ink droplets can be precisely controlled by controlling their charge and flight direction. Electric jet printing technology has the following advantages:

1. High efficiency: Electric jet printing technology can achieve high-speed and large-scale jet printing, and the production efficiency is much higher than traditional printing methods.
2. Environmental protection: The ink used in electric jet printing technology is mostly water-based ink, which is non-toxic, odorless, non-flammable, and has no pollution to the environment.
3. Low cost: Electric jet printing technology does not require plate making, reducing the cost of plate making and material waste.

II. The role of high-voltage power supply in electric jet printing

The high-voltage power supply plays a crucial role in electric jet printing. Its main functions are as follows:

1. Charging the ink: The high voltage generated by the high-voltage power supply can charge the ink, so that it can be sprayed out of the nozzle under the force of the electric field. The charge amount and charge distribution of the ink directly affect the shape and flight direction of the ink droplets.
2. Controlling the flight of ink droplets: By controlling the output voltage and waveform of the high-voltage power supply, the flight speed and direction of the ink droplets can be precisely controlled, thereby achieving accurate positioning and jet printing.
3. Preventing the diffusion of ink droplets: The electric field force generated by the high-voltage power supply can effectively prevent the diffusion of ink droplets during flight, ensuring the clarity and accuracy of the jet printing effect.

(2) Stability: The output voltage and current of the high-voltage power supply must be stable to ensure the stability and consistency of the jet printing effect.
(3) Adjustability: The output voltage and waveform of the high-voltage power supply should have adjustability to meet different jet printing needs and ink characteristics.
2. Selection points

When selecting a high-voltage power supply, the following points should be considered:

(1) Output voltage and current: According to the type of nozzle and the characteristics of the ink of the electric jet printing equipment, choose a suitable high-voltage power supply output voltage and current.
(2) Output waveform: The output waveform of the high-voltage power supply has a great influence on the flight speed and direction of the ink droplets, and the appropriate output waveform should be selected according to the jet printing requirements.
(3) Stability: The output stability of the high-voltage power supply directly affects the stability and consistency of the jet printing effect, and a high-voltage power supply with good stability should be selected.
(4) Adjustability: The output voltage and waveform of the high-voltage power supply should have adjustability to meet different jet printing needs and ink characteristics.

Take a certain electric jet printing equipment as an example. This equipment uses a high-voltage power supply to provide high voltage to the nozzle, charges the ink, and then sprays the ink out of the nozzle under the force of the electric field, forming ink droplets. By controlling the output voltage and waveform of the high-voltage power supply, the flight speed and direction of the ink droplets can be precisely controlled, thus realizing precise positioning and jet printing. In practical applications, this electric jet printing equipment can achieve efficient, environmentally friendly, and low-cost jet printing, meeting various jet printing needs.
