Offset paper

Oldly known as "Dowling paper", it is paper for books and periodicals used in offset printing machines. Suitable for printing single-color or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging materials. Offset printing paper is divided into special size, No. 1 and No. 2, with basis weight from 70 g/m2 to 150 g/m2. Pulp has high strength and printability. Offset printing is a relatively high-end printing paper for books and periodicals. It has high requirements on contrast, stretch rate and surface strength. The acidity and alkalinity should also be close to neutral or weakly alkaline so as not to affect the paper used for printing. The basis weight is 40 g/square. m to 80 g/m2. In recent years, we have successfully trial-produced low-quantity offset printing newsprint and offset printing book and periodical paper for use in offset printing paper and books and periodicals.
