What does millboard mean?
Millboard is a dense, stiff sheet made from compressed wood pulp and used chiefly in bookbinding. It is heavier and more rigid than ordinary paperboard, so it can support leather or cloth covers, form strong cases, and protect the text block. In a repaired or specially bound volume, a case made from this material gives the cover its shape and durability; bookbinders may also refer to the material by terms such as pasteboard or binder's board. Though often grouped loosely with cardboard and hardboard, millboard has a more specific role: it is a specialist board selected for stiffness rather than a generic sheet of paper. The word is chiefly associated with British bookbinding and publishing usage, although it is also understood in American English. It is normally used as a mass noun, with plural millboards available for individual sheets or pieces. Millboard's combination of humble pulp and remarkable rigidity makes it an old but still useful example of how materials and craft terminology preserve a trade's history.
