An Introduction to Digital Color Prepress

This book will introduce you to concepts and techniques related to the creation of PostScript color pages. It is intended to help you better understand digital color prepress--from the changing steps of the production cycle to the many ways software and hardware can be used. By visually and objectively explaining what digital color systems can and cannot do, we believe this book will prove useful to designers, art directors, publication managers, service bureau personnel, and in-plant production staff.

Until recently, the graphic arts industry had a range of highly specialized jobs. Designers and other document creators did not have to think about undercolor removal and gray component replacement, nor worry about density, trapping, or raster image processing. Then PostScript entered the picture and changed the way in which page design and production were done.

As a result, many of the more technical aspects that were formerly handed off to individual skilled trades people are now being absorbed by the designer and the production artist. Those in new roles, like service bureau managers, and in traditional roles, such as art directors, must now address more and more the specifics of the color separation process, in order to make informed decisions on project cost, schedule, and quality.

It is not within the scope of this book to provide a complete step-by-step guide to creating color separations in the desktop environment. Software programs and production methods vary widely and the technology is rapidly changing. In this book, we will concentrate on explaining the common, fundamental issues faced by anyone trying to create digital color pages with PostScript systems. After reading this volume, you should have a good grasp of the evolving technology, and a better understanding of this new and exciting prepress. You may purchase this and other publications using our convenient online order form.
