Newsprint is one of the least expensive printing papers.
Off-machine coaters may be used to add a single layer of coating to a paper or to add a second layer to a paper that has already been machine coated. Ink is transferred to paper from a blanket that carries an impression from the printing plate, rather than directly from the printing plate itself. Offset spray is used to prevent this. These papers are more resistant to water and less susceptible to picking. Most book and text grades of paper can be used on offset presses.
