gluing a text block into its hardcover case
The bookbinding step that glues a finished text block into its hardcover case, the moment a block becomes a hardback. It runs after the block is sewn or glued and before pressing forms the joint, and it is where hardback unit cost separates from a paperback's perfect binding. On single-copy work it is the finishing line, not the press, that sets the floor on price and lead time.
