PBT International Ltd.
PBT International Ltd was founded in the UK in 1984 and rapidly became a major independent producer of toner based imaging systems for desktop laser printers. The company's Xinia brand has become a UK leading brand for aftermarket printing supplies

PBTI has trained and licensed leading companies in Japan, USA, India and Australia in the manufacture of printer cartridges.

In October 2014, industry leader Turbon AG acquired the Xinia brand from PBTI, incorporating cartridge manufacturing into its state of the art production facilities.

With the cessation of large scale cartridge production at its Wells headquarters, PBTI's focus is on the development and sale of speciality imaging systems for a variety of global markets and industries.
