This Highbright Copy Paper makes full use of ColorLok Technology to provide more vivid colors for richer, brighter images and graphics, bolder blacks for crisp sharp text, and faster drying for less smear and faster handling time. You get consistent, reliable results in standard copy machines and inkjet and laser printers. While ordinary copy paper offers a brightness range in the 80s, Highbright gives you a full brightness, no show-through for double sided copying or printing, clean cut edges, clean dust-free surface and controlled moisture content to prevent curling. SFI Certified.
