New thermal printheads deliver fast print speed

These devices are optimised for barcode label printers applied in logistics and inventory management.

In recent years, the growth of the e-commerce (EC) market and diversifying customer needs have increased the demand for logistics and inventory management labels. Conventional thermal printheads, however, are limited to printing speeds ranging from 250mm/s to 300mm/s. In response, ROHM developed high speed and highly reliable thermal printheads that leverage novel structures and technologies. The key goal: achieving a level of print quality and durability that exceeds conventional limits.

The TE2004-QP1W00A (203dpi) and TE3004-TP1W00A (300dpi) significantly improve on the substrate material, structure, and wiring pattern over existing products. In particular, the heating elements, which affect printing speed and quality, adopt a new design using ROHM’s original 3D processing technology to achieve a print speed of 500mm/s.

On top, applying a two-layer high-hardness protective film to the head increases resistance to abrasion and static electricity for high-speed printing along with corrosion caused by moisture and salt, extending service life considerably.

In the future, ROHM will continue to improve the efficiency of label printing in various industries by applying these technologies to new products.
