As color printing becomes more prevalent in the home, home office and business, HP and International Paper continue to develop new ways to increase performance and output quality through the role of the paper within the printing system.

“ColorLok technology was co-developed by integrating HP’s ink technology with International Paper’s manufacturing expertise,” said Greg Gibson, vice president and general manager, Commercial Printing and Imaging, International Paper. “Customers will enjoy new benefits with this technology that until now was only available through laser printing.”
