The paper grade is a 100% de-inked, post-consumer waste silk grade and was sourced in partnership with printer Geoff Neal Litho.

Chris Fidge, sales director at Geoff Neal Litho, said that the paper used needed to be a recycled coated grade.

He said: "Given the fact that the brochure produced for Sky needed to have good printing results to ensure absolute clarity of the images, it was essential that the chosen stock would dry successfully without any loss of colour intensity."

He added that the printer prided itself on its environmental effort and used vegetable inks as standard, sourcing all of its energy needs using renewable sources.

Revive pure white silk is exclusive to Northampton-based paper merchant Robert Horne and comes in a variety of weights and sheet sizes.
