The incredibly smooth surface of this Everyday Multipurpose Paper is made with 30 million fibers per gram for superior formation. Even, high-density surface produces copies as sharp as the original whether in black & white or vibrant color. Bright-white paper produces an impeccable print contrast & resists fading. High opacity does not allow ink to show through when printing double-sided. Low-ash content keeps machines moving & prolongs copier life. Jam-free paper is independently tested to run through a high-speed copier for 24 hours at one-page-per-second without a single jam. Acid-free, letter-size paper archives your important information with superior quality for years to come.
