The main use for newsprint is newspapers, with smaller amounts being used for magazines, inserts, comics and general commercial printing. Newsprint represents about 25% of the cost of newspaper production. Standard newsprint is printed mainly on CSWO (cold set web offset) offset and letterpress, but flexography is increasingly an option. Grammage has progressively declined from 52 g/m2 since the 1970s.
Standard grammage: 40, 42, 45, 48.8, 52 g/m2
Improved newsprint was developed as an improvement on standard newsprint, in order to give better 4 color printing, particularly of advertisements.
