The certification covers the printer's Chelmsford, Basildon and Rettendon sites and, according to the company, is the result of customers showing more of an interest in how print affects the environment.

Philip Reed, systems manager at Redlin Print, handled the ISO accreditation process, which took 10 months and comes a year after the company secured FSC certification.

Sales director Steve Lawrence said: "When our customers choose Redlin to produce their print, they can be confident that environmental issues are taken seriously and that the business is committed to continually reducing the negative effect it has on the environment.

"ISO 14001 also backs up Redlin’s FSC certification, which gives customers the choice to select a paper that is sourced from well-managed forests."
