Inkjet Printing is a coding method that uses inkjet technology to spray characters or patterns onto the surface of an object. It is high-speed, non-contact, and is suitable for the coding needs of various materials.
Inkjet is generally divided into small character inkjet (CIJ), thermal inkjet (TIJ), piezoelectric inkjet (PIJ), and solenoid valve inkjet (large character). Among them, small characters and piezoelectric type can only print dot-matrix characters, which are collectively referred to as small characters; thermal inkjet and solenoid valve technology can print both dot-matrix characters and solid characters, they are collectively referred to as high-resolution inkjet printers. We focus on small character inkjet (CIJ), and thermal inkjet (TIJ).
