Although it's still common for people to talk about making a 'carbon copy' of something, carbon paper is an unfamiliar concept to many of those who have grown up in the computer age.

It was also used when making credit card payments, with the card details being copied onto the paper for the vendor to keep.

A succession of inventions, ranging from photocopiers to chip and PIN machines, has rendered carbon paper all but obsolete.

BBC News went to meet production director Mervyn Jones to find out how the company has remained in business.
