The company, which consists of Data Lateral, Dialogue Solutions, Howitt and Shift Click, is the latest to join the scheme, which aims to challenge the environmental misconceptions of paper.

Nick Dixon, Lateral Group chief executive, said he hopes the campaign will challenge the misrepresentations that many customers and some of the industry still hold.

He said: "The more that can be done to inform individuals and put paper use in a more balanced perspective, the better."

However, he added that the economic situation is having an impact on the number of printers that are signing up to the scheme.

"We have to make sure that the right image of paper use is put across, which is why we need more printers on board the Two Sides scheme. Small sums of money can make all the difference," he said.

The main objective of the campaign is to communicate the benefits of paper, and facts regarding its sustainability and environmental impact.

Companies such as Sun Chemical, Fuji and many paper producers and distributors have already joined Two Sides. Printers can join the campaign for £25 per million of UK turnover, although there will be a minimum of £150.

The NAPM launched the three-year campaign in October last year.
