Paper commonly used for ring linings includes offset paper, coated paper, and mica paper.
Off-liner paper used as offset paper is mostly white. Different grades of books and periodicals use different quantities of ring backing paper. For general publications, the quantitative amount is 60 to 150 g/m2, and for higher-grade books and albums, the quantitative amount is 200 to 250 g/m2. In order to avoid wrinkling during pasting, the direction of the silk lining paper should be parallel to the spine.
Coated paper is used as ring backing paper for higher-grade books and magazines. The basis weight is generally between 100 and 250 g/m2. Decoration patterns related to the contents of the book may also be printed to increase the decorative effect of the books and periodicals.
