A large character inkjet printer refers to an inkjet printer capable of printing characters larger than 18mm. It is widely used for printing on various shapes such as cartons, woven bags, sheets, rolls, etc., and is applied in industries like food, chemical, steel, metallurgy, medicine, and daily chemicals. There are two types of ink used in large character inkjet printers (also known as consumables): one is the ink cartridge (most of which are provided by HP), and the other is the ink (achieved through adding ink to the machine for printing). What's the difference between large character inkjet printers and small character inkjet printers? Today, we will explain the differences in ink between large character inkjet printers and small character inkjet printers.

The internal ink pipeline and ink nozzle components of a small character inkjet printer are quite numerous. The ink travels through a long pipeline before reaching the nozzle. Moreover, the charge and viscosity values of each ink droplet must be within a standard range, so that the ink droplets charged will not deviate from their normal positions during flight. Therefore, small character inkjet printers have very strict requirements for ink. The main features of large-character inkjet printers are that the ink supply route is short, not in a closed loop, and all indicators are stable. Therefore, their failure rate is much lower than that of small-character inkjet printers. Large-character inkjet printers are widely used for printing on outer packaging, but their printing speed is limited. The difference between the ink for large character inkjet printers and that for small character inkjet printers
1. From a chemical perspective: The ink for small character printers is conductive, while the ink for large character printers is non-conductive. This is due to the different working principles of each type of printer. 2. From a physical perspective: The viscosity of the ink for small character printing machines is higher than that of the ink for large character printing machines. Moreover, the filtration accuracy of the ink for small character printing machines is much higher than that of the ink for large character printing machines.
