As a TIJ System Supplier, share with you. Thermal Inkjet Technology uses a
thin film resistor to heat less than 0.5% of the ink in the ink ejection area to
form a bubble. This bubble expands at a very fast speed, forcing ink droplets to
eject from the nozzle. The bubble continues to grow for a few microseconds, then
disappears back to the resistor. When the bubble disappears, the ink in the
nozzle retracts. Then the surface tension will generate suction, pulling new ink
to replenish the ink ejection area. Thermal inkjet technology is structured by such an integrated cycle technology program. In the piezoelectric inkjet
technology, the ink is ejected from a nozzle similar to the thermal inkjet
technology, but the formation method is formed by reducing the area where the
ink is ejected. The size of the ejection area is controlled by applying voltage
to one or more piezoelectric plates in the ejection area. Because the ink is
prone to chemical changes at high temperatures, the directionality and volume of
ink particles are not easy to grasp, and the edges of printed lines are easy to
be uneven, which affects the printing quality to a certain extent, which are its
shortcomings. The micro-piezo print head technology uses the discharge
characteristics of the crystal under pressure to stably eject ink at room
temperature. It has the characteristics of strong control of ink droplets, easy
to achieve high-precision print quality of 1440dpi, and the micro-piezoelectric
inkjet does not need to be heated, and the ink will not undergo chemical changes
due to heat, thus greatly reducing the requirements for ink. Liquid inkjet
printers represent the mainstream products in the market.

When an inkjet printer prints an image, a series of complicated procedures are required. When the printer nozzle quickly sweeps the printing paper, the countless nozzles on it will eject countless small ink droplets to form the pixels in the image. Generally, there are 48 or more independent nozzles on the printer head to eject various colors of ink.
Generally speaking, the more nozzles, the faster the printing speed. Ink drops of different colors fall on the same spot to form different complex colors. It can be observed with a microscope that the place where the yellow and blue-violet inks are ejected at the same time is green, so we can think that the basic color of the print is formed in the inkjet overlay. By observing the simple four-color inkjet working method , We can easily understand the working principle of the printer: each pixel has 0 to 4 ink droplets covering it. Different combinations can produce more than 10 different colors. Some printers can also produce 16 different colors through a combination of colors, such as "cyan and black" or "magenta, yellow and black".
