Offset paper, formerly known as "dolly paper", is mainly used for printing higher-grade color prints by lithographic (offset) printing presses or other printing presses. It is suitable for printing single-color or multi-color book covers, texts, inserts, pictorials, maps, posters, color trademarks and various packaging products. Offset paper is divided into special, No. 1, No. 2, and No. 3 according to the ratio of pulp, and has high strength and printability. There are single-sided and double-sided, and there are two grades of super calendering and ordinary calendering. Offset paper has low elasticity, uniform absorption of ink, good smoothness, compact and opaque texture, good whiteness, and strong water resistance. Conjunctival offset ink and high-quality lead printing ink should be used. During the production process of offset paper, a slitting machine is needed to cut the wide offset paper into multiple narrow materials for easy use during printing.
