THOUSANDS of Glastonbury Festival goers will be wearing t-shirts printed by a Westbury firm as they boogie to their favourite bands.

T Shirt and Sons has been named as official merchandise supplier to the 2005 festival and director Andy Lunt says business has never been better.

Workers at the company, based on the West Wilts Trading Estate, are now waiting for Glastonbury organisers to reveal this year's designs before printing gets underway.

Mr Lunt, 39, who runs the firm with his brother Jon, 42, said: "Michael Eavis (festival organiser) has very strong views about locality. They were using a London firm before, but we did it for the first time in 1993.

"It took a lot of work to get it done on time, but now we can do it in two or three days.

"They come up with three or four designs. They've got some favourite artists they use and also have design competitions."

The brothers set up T Shirt and Sons in Bath in 1989 and it moved to Westbury 18 months ago after outgrowing its former premises.

The festival contract is one of its most prestigious, but the company also prints t-shirts and uniforms for anyone from rock bands Radiohead and REM to Oxfam, Sainsbury's and 20th Century Fox.

The company has just won second and third place in the National Printwear and Promotion Exhibition Printing Awards.

It became the first UK printing firm to be accredited by the Ethical Company Organisation (ECO) and Mr Lunt says this ethos has helped secure many clients.

One of the firm's biggest clients is Fruit of the Loom and Mr Lunt said he was pressing bosses to ensure they were not exploiting cotton workers.

T Shirt and Sons uses 'discharge printing' techniques and 99 per cent of its garments have water-based dye, which makes the colour longer-lasting.

The company, which employs 11 staff, is likely to print half a million t-shirts this year and Mr Lunt is now looking to build up its roster of local clients.

He said: "We have had up to 16 staff in the past, but the move to Westbury has made us so efficient. We've never done so well as we're doing at the moment.

"A lot of people think you need to go to London to get things done, but there's usually something around the corner."
