While the printer has been engaged in putting the manuscript into
type, the publisher has had a designer at work upon a cover sketch,
and an artist upon such illustrations as the book requires. All this
has to fall in with the publisher's general scheme for the book as a
whole. The designer must know what limits are placed upon him as to
the number of inks or foils, or the amount of gold-leaf which he may
employ. The artist must know whether his pictures are to be drawn for
full color, two-color or one-color plates. In deciding these questions,
the publisher is influenced by what he believes the book to require in
its appeal to the public, and how great an expense is warranted by the
probability of its success.
