Formerly known as "Daolin Paper", it is mainly used for lithographic (offset) printing machines or other printing machines to print high-grade color printed matter, and is suitable for printing monochrome or multicolor book covers, characters, inserts, pictorial, maps, posters, color trademarks and various packaging products.

Offset paper is divided into special number, 1 number and No.2 and No.3 according to the proportion of pulp, which has high strength and good printability. There are single-sided and double-sided, and there are two grades of super calendering and ordinary calendering. Offset printing is a kind of advanced printing paper for books and periodicals, which requires high contrast, expansion rate and surface strength, and the pH value should be close to neutral or weakly alkaline so as not to affect the printing paper.

Offset paper has small flexibility, uniform ink absorption, good smoothness, compact and opaque texture, good whiteness and strong water resistance. Conjunctival offset printing ink and good quality lead ink should be selected. The viscosity of ink should not be too high, otherwise there will be powder removal and galling. Also to prevent the back from getting dirty, generally use antifouling agent, dusting or lining paper.

For example, the inside pages of books, newspapers, notebooks, A4 printing paper and post-it notes,
