A Thermal Inkjet (TIJ) egg printer heats a tiny resistor in the cartridge to form a bubble that pushes a precise drop of ink onto the shell. It is the same high-resolution technology used in office inkjet printers, adapted for industrial food coding.
TIJ heads reach 300–600 DPI, giving crisp text, barcodes and QR codes. Cartridges are clean, plug-and-play, and many are refillable with food-grade ink. There are no ink tubes to clog, which lowers maintenance.
Because TIJ is non-contact and fast, it is the most common choice for egg coding lines that need clear, compliant marks at high throughput.
