Producing ColorLok® Papers

All papers that carry the ColorLok brand must meet a concise set of paper surface quality, physical and electrostatic performance metrics across a variety of factors related to image quality, dry time, and printer runnability. HP can provide detailed ColorLok® specifications under a confidential disclosure agreement (CDA) to paper companies and partners interested in joining the ColorLok Program.

The Printing Applications Laboratory at Rochester Institute of Technology (RIT-PAL) has qualified as an official "testing center" where any paper company or private label owner may submit papers for testing and performance certification.
