In recent years, applications with a thermal print system have been rapidly expanding to emerging countries. Under the circumstances, a lot of direct thermal paper is being developed locally by many companies leaving the end-users little to no choice but to use the local paper supplier.

Unfortunately, some of this newly developed local direct thermal paper cause significant abrasions on the printheads forcing the users to replace the printheads frequently.

Considering the situation, ROHM has developed a durable thermal printhead which can achieve three times longer life compared to conventional printheads, even with such severe locally manufactured medias. In addition, the new printhead has 15% improved energy-efficiency and contributes to the ability of accepting a low-sensitivity direct thermal paper.

We have also developed AST (Anti Sticking Treatment) technology to prevent a sticking problem which causes a poor print-quality. The treatment also reduces paper residue build-up on the surface of printheads and keeps a good print-quality for continuous printing.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
