Colorimetric—The Colorimetric CRD is designed for very basic color
matching and one-to-one conversion from CIE color to CMYK color.
With Colorimetric chosen as the printer default CRD, all colors are
reproduced exactly unless a specified color is “out of gamut” (out of the
printer's range). For out of gamut colors, the Colorimetric CRD substi-
tutes the closest “in-gamut” color. The result is that exact color matches
between the two devices are maintained wherever possible, but the
printed image may have a smaller range of colors than the original
image (since several image colors may be mapped to a single printer
color). We recommend that you use this CRD for printing spot colors.
Business—The Business CRD matches the images on a monitor as
closely as possible (WYSIWYG). Use the Business CRD for com-
puter-generated graphics.
Photographic—QMS developed the Photographic CRD to optimize
the quality of photographic images and other images with many sub-
tle color shifts. Like the Colorimetric CRD, the Photographic CRD
substitutes out-of-gamut colors with in-gamut colors, but it also
adjusts (compresses) all other colors (whether in-gamut or out-of-
gamut) as necessary to maintain the proportional relationship
between the colors.
