Chapter 22. Preferences > Color management

Color management

What is color management?

Every device, whether it's a monitor or printer, defines color within its own unique color range (called its “gamut”) when it represents or reproduces color. The purpose of color management is to ensure consistent color by coordinating and matching color between various device gamuts—from monitor color (RGB) to final print output color (CMYK). If color on a source device (monitor or scanner) is within the gamut of the destination device (printer), then color matching is straightforward. If color on a source device is outside the gamut of the destination device, then the color management system adjusts the color (alters its hue, lightness, or saturation) to match the color between devices. A monitor can't display, nor can a printing device output, all the colors in the visible spectrum.

Color management for Web docs?

The Color Management preferences are not accessible for Web documents. According to Quark, Inc., this is because at the present time the monitors used by Web viewers don't have uniform standards for color definition, representation, or calibration. So for Web documents, there wouldn't be any guidelines for choosing preferred or optimum settings for the Color Management Preferences dialog box anyway.

We do recommend that you apply Web-safe colors to graphics that you create in a drawing or image-editing program for import into a QuarkXPress Web document, and that you also stick with Web-safe colors for items and text in your QuarkXPress Web document.
