"Case" binding:
• creates hardbound books (a.k.a. hardcover, "hardback")
• "casing in" makes the hard cover project beyond the
edge of the pages
• either glued or sewn book blocks may be used
• book blocks must first be "rounded" to give the book
block a convex (i.e. protruding) binding edge
• next, the blocks have to be "backed" by flaring the
binding edges of the signatures outward; this makes the bind more
flexible
• endpapers, a binding strip, a gauze layer known as the
"crash," and decorative headbands are then applied to the book block,
which is fastened to the cover with glue
Case binding is done in three ways:
• edition binding (automated process for long runs)
• job binding (for short runs requiring specialty hand
work)
• library binding (high-durability method for books in
public and university libraries)
