The new envelopes have been produced in a 100gsm finish, some 20gsm lighter than before, in response to market demands.

The specialist range is guaranteed for both mono and colour desktop printers, and has been specially engineered for both laser and ink-jet printers.

The range comes in two formats, DL and C5, and in the CX22 smooth finish. A thinner micron silicone strip has also been applied, along with an opacifying internal printed wash.

The envelopes are available in Conqueror's top three shades of diamond, brilliant and high white.
