1. Introduction
1.8.1 Book Size Chart
The physical parts of a book are defined as fol-
lows and will be referenced as such throughout
this manual. Book dimensions are referenced
as
“spine length” x “top (or bottom) edge length”.
Spine:
The edge of a book where the pages
are bound together.
Top edge:
Also known as the head, the top
edge is the edge of the book that is facing away
from the reader.
Bottom edge:
Also known as the foot, the bot-
tom edge is the edge of the book that is facing
toward the reader.
Face:
The face or fore-edge is the edge of the
book from which it is opened.
Book block:
A book block is the printed and
collated form of a book that does not include the
cover. It contains all front and end matter as
well as the text block.
Untrimmed book:
An untrimmed book is a
book block that has been bound with a cover but
has not yet been trimmed to finish size.
Trimmed book:
A trimmed book has been
bound and trimmed to a finish size.
The charts on Figure 1-2 can be used to deter-
mine if a specific book layout can be trimmed by
the CMT-330TC. Using the trimmed spine
height (h) and the bottom trim (x), make sure the
desired book size falls within the shaded region
of the chart. The overall untrimmed and
trimmed book dimensions must also be less
than the maximum allowed (See 1.8 Specifica-
tions).
The CMT-330TC software will not allow a book
to be cut outside this range. The operator
should be aware of these size constraints before
books are printed.
