Vision London managing director Deborah Hall said that the contract followed the opening of its office in the capital 12 months ago.
"We opened the office to assist the publishing and mail order companies in London that demanded a 24-hour service," she said.
Vision London currently holds the reprographic contracts for JoJo Maman, The Children's Warehouse, Panache and The Cotswold Company.
It also has clients in the publishing sector, including Illustrated London News, Forward Publishing and Dennis Publishing.
The firm's Milton Keynes division, Vision, also operates in repro, design, artwork and photography. Clients include Millets, Blacks, One Up Golf and Lakeland.
