In modern manufacturing, product coding and marking play a critical role in ensuring product traceability, quality control, and regulatory compliance. One of the most widely used technologies for this purpose is the Thermal Inkjet (TIJ) coding system.

Thermal Inkjet coding machines are industrial printers that apply high-resolution codes such as expiration dates, batch numbers, serial numbers, barcodes, and QR codes onto products or packaging surfaces.

But what exactly is a Thermal Inkjet coding machine, how does it work, and where is it used?

What is a Thermal Inkjet (TIJ) Coding Machine?

A Thermal Inkjet (TIJ) coding machine is an industrial coding and marking system that uses inkjet technology to print high-resolution information directly onto various surfaces.

The TIJ technology works by heating the ink inside the cartridge and ejecting micro droplets onto the surface. This process produces sharp, clear, and highly readable prints.

Most TIJ systems use HP TIJ 2.5 cartridge technology, which is known for its reliability, easy operation, and maintenance-free design. Because of these advantages, TIJ printers are widely used in modern production lines.
