Introduction

The Fiery Color Reference Glossary defines words in bold—for example, output profile—that appear throughout this manual. Color terms and concepts, such as “color space,” “spot color,” “gamut,” and “source profile,” are used throughout this manual. If you are new to desktop color, or if any terms are unfamiliar, check the Glossary.

Key features of ColorWise

ColorWise is the color management system (CMS) built into the GA-1121 and designed to provide both casual and expert users with the best color output for a variety of purposes. The ColorWise default settings provide high-qualityout-of-box color from many Windows and Mac OS applications. This allows casual users to achieve quality output without knowing about or changing any color settings on the GA-1121.

For consistent color, calibrate the GA-1121 on a regular basis. ColorWise Pro Tools include an easy-to-use calibrator, which allows you to calibrate using either the scanning unit that is part of the copier/printer or a spectrophotometer or densitometer (see Chapter 2).

ColorWise features allow you to modify printing results. Depending on your particular needs, you can:

Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset press standards.

Match PANTONE and other spot colors for the best match when printed using four-color press conditions or when printed using presses with extra, custom plates.

Select a color rendering dictionary (CRD), also called a rendering style, for RGB printing. CRDs allow for rich, saturated printing of presentation graphics; smooth, accurate printing of photographs; and relative or absolute colorimetric rendering for specialized needs.

Define the source of incoming RGB color data for better screen matching and provide for better color conversion of RGB data with no source information.
