The continuous jet jet printer (continueinkjetprinter) is abbreviated as cij type.
The inkjet printer is a software controlled, non-contact inkjet marking system. It applies a certain pressure to the ink in the system by controlling the internal gear pump or supplying compressed gas from outside the machine to cause the ink to be ejected through a nozzle of several tens of micrometers. And the crystal oscillating signal applied above the nozzle splits the continuous ink line into ink droplets of the same frequency, equal size and a certain spacing. Then, the ink droplets are respectively charged when passing through the charging electrode, and the amount of electricity charged by the central processing unit CPU Control is carried out; after the detection electrode detects whether the actual charge and phase of the ink droplet are correct; after the Zui, the charged ink droplet deflects in the deflection electric field formed by the deflection electrode, and is emitted from the nozzle, and is respectively placed on different surfaces of the product to form a place. Need a variety of text, graphics and other signs. Instead of being charged, the ink droplets are driven into the recovery tank and re-entered into the ink circulation system inside the machine.
Because ink jetting is continuous, continuous inkjet encoders can use many types of inks, especially those that dry very quickly (within 1 second). Continuous ink jet coding techniques are therefore ideal for printing products that have a non-permeable surface (such as cans and plastics) that require rapid processing after printing. In addition, pigment inks with more vivid colors can be used.
Since continuous printing has a relatively high jetting speed, the printing distance of continuous printing is usually much longer than that of pulse printing (generally more than 10 mm), and the printing quality does not decrease. The placement of the nozzle position allows for a greater choice.
Most industrial inkjet systems use cij technology. The industrial cij printing system can reach speeds of up to 1,000 feet per minute, much faster than dod, but the quality of the image is also lower than that of the dod technology. Cij is the solution for a large number of direct mail order operations, the numbering and marking of packaging and printing products for food, beverages, pharmaceuticals and beauty. It is also used for marking and encoding lottery tickets.
The dropon demand is referred to as the dod type.
The industrial on-demand ink supply system nozzle is composed of a plurality of high-precision valves. When the word is sprayed, the corresponding valve of the font type is quickly opened and closed, and the ink is ejected by the internal constant pressure to form characters or figures on the moving surface. A digital signal produces a drop of ink on paper rather than an ink stream. Zui's new dod printhead, the color is formed on paper with a more precise collection of dots, similar to traditional offset printing. Therefore, in the four-color high-precision printing where quality is an important factor of Zui, dod is an ideal choice for Zui, which can produce effects close to photographic quality. Dod prints at speeds between 100 and 300 feet per minute. Dod uses include wide format printing, color icons for packaging, shopping point display cards, fabrics and large format logos. However, in the industrial packaging industry, due to the limitation of printing speed, it cannot be applied to high-speed packaging lines. Many companies are developing high-speed dod printing equipment for packaging applications, with nearly a dozen brands in Europe alone.
Dropon demand is referred to as the DOD formula.
The printer of DOD working principle is divided into three types, piezoelectric inkjet technology, pressure valve inkjet technology, thermal foaming inkjet technology, piezoelectric inkjet technology: piezoelectric inkjet printer Called high resolution printer or high resolution printer. The integrated nozzle has 128 or more piezoelectric ceramic crystals to control the nozzle holes on the nozzle to be processed by the CPU, and then output a series of electrical signals to the respective piezoelectric crystals through the driving board, and the piezoelectric crystal is deformed. The ink is ejected from the nozzle and forms a dot matrix on the surface of the moving object to form text, numbers or graphics. Then, the piezoelectric crystal returns to its original state and new ink enters the nozzle. Because of the high density of dots per square centimeter, piezoelectric technology can be used to print high-quality text, complex logos, and barcodes.
2, pressure valve type inkjet technology is also called large character inkjet printer; the nozzle has 7 groups or 16 groups of high-precision intelligent micro-valves, the characters or graphics to be printed at the time of printing through the processing of the computer motherboard, through the output board A series of electrical signals are output to the intelligent miniature solenoid valve, the valve is quickly activated, and the ink is ejected by the internal constant pressure into the ink dots, and the ink dots form characters or figures on the surface of the moving inkjet printing.
TIJ working principle Thermal foaming inkjet technology (ThermalInkjetTechnolog referred to as TIJ. Thermal foaming inkjet technology uses a thin film resistor to heat less than 0.5% of the ink in the ink ejection zone to form a bubble. This bubble Extends at a very fast speed (less than 10 microseconds), forcing ink droplets to eject from the nozzle. The bubble continues to grow for a few microseconds and then disappears back into the resistor. When the bubble disappears, the nozzle's ink shrinks. Back, then the surface tension creates suction, pulling new ink to replenish into the ink ejection area. Thermal foam printing technology is constructed by such an integrated cycle technology program.
