1. Principles and Characteristics of Inkjet Printing Technology

Inkjet printing is a printing technology that sprays ink onto the surface of the substrate in the form of tiny droplets, and controls the position and number of the droplets by computer to form images and texts. It is mainly divided into two types: piezoelectric inkjet and thermal foaming inkjet. Piezoelectric inkjet uses piezoelectric materials to deform under the action of an electric field, squeezes the ink cavity and ejects ink droplets from the nozzle; thermal foaming uses a heating resistor to heat the ink locally to form bubbles, and the bubbles expand to squeeze the ink droplets out of the nozzle. Whether it is piezoelectric or thermal foaming, both are non-contact printing, which is different from traditional printing and laser toner printing in terms of imaging and printing methods.

• Inkjet printing is highly flexible and does not require plate making. It can quickly adjust the printing content according to customer needs, realize short-run printing, personalized customization and variable data printing, and adapt to printing tasks of different batches and designs.
