4.Piezo-Electric Inkjet Printer Technology
Piezoelectric jet printer is also called high-resolution jet printer or high-resolution image jet printer. On the integrated nozzle, 128 or more piezoelectric crystals control multiple nozzle holes on the nozzle board respectively. Through CPU processing, a series of electrical signals are output to each piezoelectric crystal through the driving board. The piezoelectric crystal is deformed, so the ink is ejected from the nozzle and falls on the moving object. The surface of the product forms a dot matrix, thus forming words, numbers or graphics. Then, the piezoelectric crystal is restored to its original state. Because of the surface tension of the ink, the new ink enters the nozzle. Because the ink dot density per square centimeter is very high, the application of piezoelectric technology can print high-quality text, complex logo and bar code information.
