Your book's cover is the first thing a prospective reader sees; Covers are very important, unless you have a cover concept and are willing to obtain original art yourself, we suggest to hire a specialist in cover design.
Covers are almost always printed in process color, or four inks — cyan, magenta, yellow, and black — blended together on the printed page to produce a range of colors. Not every visible color can be represented in ink. Some publishers also have the covers embossed or foiled, or add a fifth ink in a spot color. A spot ink is mixed before printing so that it will be the exact color desired.
Covers are laid out in a flat, a single sheet of paper for front, spine, and back. The paper is larger than the actual cover to allow room for the bleed, where the ink extends past the design. The bleed will be trimmed later. The designer needs to know the final trim size of the book, the number of pages, and the paper used. These last two details allow the designer to calculate the spine width.

Typesetting and layout involves setting the book's text and graphics into a layout according to the designer's specifications. Extra spaces and carriage returns, unneeded tabs, and manual page breaks all have to be removed. The typesetter will look for poor hyphenation, large gaps between words, and other issues that affect the page's beauty and readability. We use page layout software, like Adobe Page maker, Adobe InDesign or QuarkXPress,
