The company had to revise its management system and training staff in appropriate areas, including verifying paper sources.

Initially, Maincolour had only intended to apply for certification from the FSC, which promotes responsible management of the world's forests.

However, ahead of the final audit by the Control Union, it decided to go for the PEFC scheme, which too promotes sustainable forest management through independent certification.

Managing director Les Field said: "This prestigious recognition means that we are one of approximately 270 printers out of a total of about 10,000 nationwide, and indeed one of only a handful of similar-sized operations in the North West, to have reached this standard.

"The certification means that any customer using our services can be assured that we recognise the importance of being environmentally aware and we are 100% committed to sustaining the world's forests.

"From both a moral and commercial point of view it made absolute sense for us to take this step."

He added: "In an age where sustainability is becoming increasingly important, our customers are similarly aware and often insist on the provision of certified products when sourcing their printed material."
