Color Management Systems
The material for a given project may originate on a variety of devices (digital camera, scanner) and/or be
produced or edited using a variety of software applications (QuarkXPress™, Adobe® Photoshop®,
CorelDRAW®, the GIMP). Furthermore, the project might use a variety of proofing methods and require
output in more than one medium. Variations in color across devices and applications make it difficult to
consistently and reliably produce professional looking results.
Color management systems developed to provide a practical means for producing consistent, reliable color
across devices and applications, and these systems rely on three elements:
1. Device color profiles
A device color profile describes all the relevant color characteristics of a particular device, including its
color space, gamut, gamma, and white point.
2. Device-independent color model
A device-independent color model describes all possible colors, independent of whether a color is
created using light or pigment. It permits the color management system to map color from the color
space of one device into the color space of another.
3. Calibration and monitoring of devices
The physical devices in the workflow must be carefully calibrated and subsequently monitored over time
to minimize any fluctuations in their representation of color.
The effectiveness of the color management system depends on the precision with which the device profiles
describe their respective devices as well as on the careful calibration and ongoing monitoring of all devices in
the production workflow.
Color Management in PlanetPress Design
Objectif Lune approached the issue of color management with an eye to making it as straightforward and
convenient as possible for its customers. It designed the color management in PlanetPress Design to
accurately display, in the Page area, the colors that print when the document executes on a printer.
When you set up color management in PlanetPress Design, you are setting up a relationship between two
color profiles: a monitor profile and a printer profile. The color management workflow in PlanetPress Design
consists of two basic steps:
1. Install the device color profiles.
You install a profile for each monitor you intend to use during document design with PlanetPress Design,
and for each printer on which you intend to execute your documents. PlanetPress Design uses version
2.0 of the Image Color Management (ICM) system. The ICM system supports device profiles that
conform to the International Color Consortium (ICC) color profile specification.
2. In PlanetPress Design, select the appropriate monitor profile for your monitor and the appropriate
printer profile for the printer on which you intend to print the document. If the printer and/or monitor
you use is document-dependent, you may need to adjust the profiles you use on a per document basis.
