Newsprint

Lightweight, with a basis weight of 30 pounds or less, it is a relatively inexpensive grade of paper. Newsprint, also known as white paper, is the primary paper used for newspapers and books; it is suitable for the body text of newspapers, periodicals, textbooks, comic books, and similar publications. Characteristics of newsprint include: a loose, lightweight texture with good elasticity; excellent ink absorption, ensuring ink adheres well to the surface; smooth, lint-free finish on both sides after calendering, resulting in clear and rich impressions; adequate mechanical strength; good opacity; and suitability for high-speed rotary press printing.

Produced from mechanical wood pulp (or other chemical pulps), this paper contains significant lignin and impurities, making it unsuitable for long-term storage. Prolonged storage causes yellowing, brittleness, poor water resistance, and unsuitability for writing. Must use newspaper or book printing inks with moderate viscosity. Strictly control plate moisture during lithographic printing.
