1-Utilize The Signatures You Pay For
With book printing you will have your page count rounded up to be at least 8 pages for the last signature, so rather than blanks use it to your advantage, whether for images, credits, “notes” etc.
2-Provide Correct File Types
Most book printers today only want high resolution PDF files. It is more cost effective for them to RIP (process) and you will pay more if you only provide native files. Each press has different PDF requisites, so ask before sending your files.
3-Don’t Jam In Images
Size your images in Photoshop rather than doing so in your document program to “fit the image box”. You are creating a much larger file in the end and this can cause potential problems during the book printing RIP.
4-Know The Safety Area On A Page
Most book presses want 3/8ths of an inch all around for safety, as book printing presses tend to be older technology and have more jiggle than a modern heat set press.
5-Create Easy Covers
Book printing is not a science, it is a craft and things can easily go wrong. If you allow the background art to flow over the front cover, spine and back cover the book printer has more latitude in creating a pleasing end result by manipulating the cover during bindery.
6-Dont Over Design
Remember, book printing presses tend to be older presses and the more complex you make your design, especially for the text, the harder it becomes to print. K.I.S.S.(Keep It Simple Stupid) in book printing works just as well as with computers.
