UFS (NYSE, TSX)

MONTREAL, Dec. 15 /CNW Telbec/ - Domtar Corporation (NYSE/TSX: UFS) today announced that it has extended the use of HP's patented ColorLok^® Technology to all of its Domtar branded business papers to provide a higher quality printing experience compared to papers that do not have ColorLok Technology. This technology will now be more widely available to customers, allowing them to keep pace with advancements in printing technology found in digital printing systems.

"We are pleased to extend ColorLok Technology, a performance-based standard, to all Domtar branded business papers, and in so doing, providing our customers with high-quality, environmentally responsible paper products, in both virgin and recycled content options," said Karin Flemming, Domtar Marketing Manager, Business Papers.

Domtar first agreed to support the performance standards of ColorLok in early 2008 by incorporating the technology into its First Choice^® line of business papers, a premium quality product with 98 brightness, and soon after with its Imageprint^® brand multiuse papers. Now Domtar Copy^®, Domtar EarthChoice^® Office Paper, Husky^® Copy and Recycled Husky^® Copy, will be available with ColorLok Technology, providing customers with a 92 brightness alternative in both virgin and recycled content options.

Paper that uses the ColorLok logo must pass a precise set of standards for print quality, as well as physical and electrostatic standards for quality and reliability. Criteria for meeting the ColorLok performance standard includes improved image quality, dry time and consistency for printer performance. For inkjet printers, the benefits of ColorLok include bolder, sharper images and faster drying times. Benefits for laser printers include reliable printing, consistent imaging and an extended printer life¹. More information about the ColorLok Paper Standard is available at www.colorlok.com.
