What is micro-piezo inkjet technology?

The micro piezoelectric inkjet technology is a patented technology developed by Seiko Epson. It places many tiny piezoelectric ceramics near the nozzle of the print head. The piezoelectric ceramics have the characteristics of expansion or contraction deformation under the action of the voltage changes at both ends. When the image information voltage is applied to the piezoelectric ceramics, the piezoelectric ceramics stretch and vibrate. Will change with the change of image information voltage, and make the ink in the nozzle under the stable state of normal temperature and pressure, effectively control the size and adjustment of the ink droplet, and eject the ink evenly and accurately, so as to obtain high precision and resolution. High-speed image color printing output, while reducing ink consumption.

Advantages compared with traditional technology

Compared with traditional thermal inkjet technology, piezoelectric inkjet technology has regular ink dot shapes, no sputtering, controllable ink dot size, controllable ejection speed, accurate positioning, can eject more liquids with different chemical compositions, and corrosion With the advantages of reduced opportunities and extended nozzle life, powdery pigment inks can also be used to prevent discoloration and fading caused by ultraviolet radiation.

For a long time, the micro-piezo inkjet technology has brought us moving printing pictures, but Epson developers are thinking: “If such an excellent inkjet technology is only applied to printers, is it a pity?” Therefore, continuous R&D and innovation have opened up the infinite possibilities of micro piezoelectric technology.
