What is the principle of UV printer inkjet printing?

Before talking about the basic principles of UV printer inkjet printing, let's talk about the current inkjet printing technology. Inkjet printing technology can be divided into continuous inkjet and drop-on-demand inkjet, the former can be divided into two-state and multi-state deflection according to the deflection mode; the latter can be divided into solid and liquid inkjet. Next, let's take a look at the principle of UV DTF printer inkjet printing.

UV printer continuous inkjet technology principle.

The principle of UV printer continuous inkjet technology is to use a stable power system to give the ink a fixed working pressure so that it continues to spurt and is separated into ink droplets under the effect of an oscillator. The automatic control system can selectively adjust the ink according to the printing information. The extra positive charge drops, and finally, the electrified positive charge is deflected according to the deflection electrostatic field, and then sprays to the surface of the printing process object to generate graphic information content. The unpowered positive charge goes straight to the acquisition equipment, which is two-state deflection; if the image is developed the positive charge is called polymorphic deflection when it is developed in different parts of the printing process object due to the required amount of charge. It is less predictable and has fewer primary uses than on-demand.

The principle of UV printer drop-on-demand inkjet technology.

UV printer drop-on-demand technology manipulates whether or not to create droplets by manipulating electronic device data signals. When the printing information is transmitted to the output terminal equipment, if the ink droplets are necessary, the ink droplets will be sprayed, and the surface of the printing process object will be prompted to produce textual information content. Compared with the ink droplet electrification equipment and deflection hardware in the continuous inkjet system software Configuration, etc. is easier. Among the drop-on-demand inkjet technology, liquid inkjet technology is popular at this stage, and it can be further divided into thermal inkjet technology and piezoelectric inkjet technology. The key to thermal inkjet technology is to use resistors to convert electromagnetic energy into energy in the whole process of heating. The heat can vaporize the ink around the nozzle of the printer, eject the ink, and print the overall image on the copy paper. target image or text. Piezoelectric inkjet technology is the use of piezoelectric sheets to cause mechanical equipment to vibrate, and the entire process of piezoelectric original control inkjet according to the working pressure, without the need to heat the printhead, environmental protection, energy saving, and increased the use of digital printing machine printheads Longevity; precise control of ink droplet size and spouting position, preventing the problem of blurred images; reducing ink selection requirements, and inks that cause chemical changes under high-temperature conditions can also be used.

The UV printing machine uses the piezoresistive inkjet technology in the drop-on-demand inkjet technology. According to the comparison between the above piezoresistive inkjet technology and the drop-on-demand inkjet technology, the advantages and disadvantages of the UV printer itself can be visualized.
