Thermal printheads print barcode labels at top speeds

High speed printing of durable labels which contribute to improved efficiency in logistics and inventory management label applications is possible with the latest printheads from Rohm, said the company. The TE2004-QP1W00A and TE3004-TP1W00A are optimised for barcode label printers applied in logistics and inventory management.

Conventional thermal printheads are limited to printing speeds ranging from 250mm per second to 300mm per second, prompting Rohm to develop these thermal printheads using what the company describes as novel structures and technologies. The result, claimed the company, achieves 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, said Rohm. The heating elements, which affect printing speed and quality, are based on a new design using the company’s original 3D processing technology to achieve an industry-leading print speed of 500mm per second.

A two-layer high-hardness protective film applied 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.

Rohm Semiconductor develops and manufactures a very large product range from SiC diodes and MOSFETs, analogue ICs such as gate drivers and power management ICs to power transistors and diodes to passive components. 

Production of these products is in manufacturing plants in Japan, Germany, Korea, Malaysia, Thailand, the Philippines, and China. Rohm Semiconductor Europe has its head office near Dusseldorf, Germany, serving the EMEA region (Europe, Middle East, and Africa).
