Thermal Inkjet (TIJ) printers use standard ink cartridge systems and do not require any bottles of inks or solvent, making thermal inkjet printers clean and simple to use.
Thermal inkjet printers use a drop ejection process, storing ink in a cartridge that regulates the pressure of the fluid. Inks are then delivered to the firing chamber and heated to more than 1,000,000 °C/second by an electric resistor. A 0.1 micrometer thick film of ink is heated to around 340°C, from which a bubble is formed to expel the ink. A droplet breaks away from this bubble causing it to collapse, the firing chamber then refills as the whole process repeats.
Laser marking permanently changes the surface of the substrate. For example, when coding onto painted card, the very top layers of paint are removed revealing the contrasting bare card underneath. The same process on plastic changes the very chemical nature of the material, either melting it to leave a mark or causing a colour change. When coding on glass, the laser leaves micro cracks, scribing a permanent code without weakening the material.
Our TIJ printers can help reduce production costs by removing labels and reducing SKUs on pre-printed packaging. While error-free coding will maximise uptime and reduce wastage.
