Multipurpose office paper works well in high-speed copiers, dry-toner plain-paper copiers, plain-paper fax machines and offset duplicators. Ideal for general copying, internal documents, and backup hard copies. Good opacity allows minimal show-through from side to side. ColorLok Technology delivers brighter colors, fewer smears and crisper text. Flat, even surface allows consistent ink and toner receptivity for reliable performance. 20 lb. office paper is acid-free for archival use.
