noun
unbound book; printed sheets
Refers to a book or set of printed sheets that are still unbound, often fresh from the printing press. Used in traditional publishing and bookbinding contexts.
刷り本を製本する前に、ページの順序を確認する。
Before binding the printed sheets, check the page order.
古い印刷所では、刷り本が山積みになっていた。

Compound of 刷り (suri, 'printing') and 本 (hon, 'book'). The spelling 摺り本 uses the older character 摺 for printing, which is now less common.
