Adobe is dedicated to providing software that allows designers to express their visual ideas, while providing tools and resources to printers to ensure that those ideas print as intended. While designers explore the creative features of Adobe Photoshop® CS4, Adobe InDesign® CS4, and Adobe Illustrator® CS4, as well as the capabilities of Acrobat® 9 Pro, printers need to take a rather different approach. You might call it "reverse engineering": inspecting, analyzing, and, if necessary, modifying customer files to facilitate printing. While this document is focused on the needs and requirements of printers, it is also useful for production artists who are preparing files for print. Some modifications (for example, replacing solid black areas with a rich black build, or converting RGB text to black-only) are dictated by the physical requirements of printing. Some tweaks may be necessary to accommodate a particular raster image processor (RIP) or imaging device. Not all workflows are the same, and solutions vary accordingly. Regardless of your particular workflow, the more you know about the tools used by designers to create files, the better equipped you are to anticipate, prevent, find, and fix problems. In addition, you'll be better able to advise your customers as they prepare files for submission. What This Guide Is Intended to Do This guide serves as both a detailed technical reference for handling Creative Suite 4 files from your customers, and as a training tool for your staff. For example, this guide will introduce you to forensic tools, such as the Overprint Preview option in Illustrator, InDesign, and Acrobat 9 Pro, as well as the Output Preview function in Acrobat, all of which are invaluable in highlighting potential problems. The earlier you can pinpoint problems in a job, the less expensive and complicated they are to rectify. As RIPs have matured and transparency flattening has become more sophisticated, there are fewer issues with jobs containing transparency. The advent of pure PDF workflows based on the Adobe PDF Print Engine will result in more reliable reproduction of PDF content-that is, greater consistency and fidelity to the designer's intent. For example, transparency effects in InDesign CS4, such as gradient feather, glow, and inner shadow effects, image without the need for flattening when output through a PDF Print Engine-based RIP. You'll find guidance in this document for identifying such effects and for preparing jobs to correctly render them during output. Additionally, you'll find links to other available reference materials that cover such topics in depth. How This Guide Is Structured Some technologies and concepts-such as PDF creation, transparency, and the Adobe Graphics Model-are common across the Adobe products used for print design and production in Creative Suite 4 Design Premium, Design Standard or Master Collection. You'll find information about such topics in the "Common Resources" chapter. This document is organized so that you can quickly find information about specific software. As a job enters production in a printing plant, its path varies according to the conventions of the particular plant, as well as the requirements of the job. But because many jobs involve the aggregation of artwork and text in an InDesign layout, it makes sense to treat InDesign as a "hub," and Photoshop, Illustrator, and Acrobat as related
