Perfect binding is one of the most secure, professional-looking,
labor-saving, and cost-effective binds available. Most perfect-binding
machines are used for larger runs, but today's machinery is
making it possible to produce even a single, on-demand book
professionally and cost effectively.
The perfect bind process involves inserting a book block
(sheets or signatures comprising a book) into a carriage clamp
that mechanically processes the book through a cutting and
roughing station. It then smooths adhesive along the book
spine, and adheres a wrap-around cover to produce a finished
book. Generally, a final step includes a three-sided trim
to clean up the finished book.
Using printed covers makes every book look like an original,
while clear acetate covers make it possible to produce perfect-bound
books without printing covers. Using custom covers allows
for unlimited print types, one-sided clear coatings, and scoring
for lay-flat properties.
Most perfect binders are very simple to use. You insert
your cover into the cover station, place your printed book
into the carriage clamp, activate the machine, and remove
the finished product. Some binders will even automatically
load your covers and eject the finished books for you. After
the book is dry, it is ready to use.
Most perfect-bound books are three-side trimmed before they
are considered a finished product. This is a simple process,
and can be accomplished with a small paper cutter or an in-line,
automated three-knife trimmer.
