Analysis of thermal foaming inkjet printer (TIJ)

Principle of hot bubble inkjet technology: the nozzle adopts semiconductor thin film technology, and uses laser process and high-precision coating technology to form multiple nozzles with a diameter of about 50 microns. These nozzles are arranged in a high density, and after receiving the heating signal, the ink is heated to about 260 °C by electric current in a very short instant, and the local ink is heated to form bubbles to expand and eject the ink.

Advantages of thermal inkjet printers

The thermal foaming inkjet printer is simple to operate, easy to install, and has powerful printing functions, which can print real-time data, barcodes, two-dimensional codes, databases and other content, and has powerful editing functions.

Thermal foaming inkjet printer has a simple structure, generally composed of three parts: host and power supply, nozzle, no filter, no cleaning and maintenance, can achieve multi-head coding, up to 24 nozzles work at the same time

Thermal foaming inkjet printer has good stability, because the thermal foaming printhead is integrated in the ink cartridge, which means that each time the cartridge is replaced, the vulnerable printhead is replaced, so the thermal foaming inkjet printer has better stability

Disadvantages of thermal foam inkjet printers

First, the printing distance requirements are high. Generally, the distance between the nozzle and the product should be controlled within 5mm, and the best printing distance is 2mm to achieve the best printing effect display.

Second, the ink used is selective for the material. This is also a problem that many manufacturers are concerned about and headache, such as clarity, adhesion, permeability, etc., generally TIJ inkjet printers are used in paper, plastic, metal, cloth and other surface permeable materials.

Third, the cost of consumables is high. A cartridge of 42 ml, with a smaller capacity, is more expensive than small character inkjet ink
