Color Workflow Terminology
This section defines the terms used in the RGB and CMYK workflow.
•
CSA (Color Space Array)
is the spectrum of specific variants of a color
model with a specific gamut or color range. For example, within the
color model RGB, there are numerous color spaces, such as Apple
RGB, sRGB, and Adobe RGB. While each of these define color by the
same three axes (R, G, and B), they differ in gamut and other
specifications. CSA is comprised of a three-dimensional geometric
representation of colors that can be seen or generated using a certain
color model and are quantitatively measured. Source CSA is to be used
only under the assumption that the upstream color workflow was
managed and monitored. Otherwise it should be replaced with a Creo
profile, which is the default.
•
CSA Profiles:
There are three CSA profiles with gammas of 1.8, 2.1 and
2.4. The higher the gamma, the darker the RGB appears. This
workflow should be used when you have images from different
sources, such as digital cameras, Internet, and scanners and you want
the images to have the common RGB color spaces.
Other possible CSA profiles are sRGB and Adobe RGB.
•
Rendering Intent:
All printers, monitors and scanners have a gamut or
range of colors that they can output (or view in the case of a scanner).
If a color needs to be output and is outside the gamut of the output
device, it must be mapped or approximated to some other color, which
exists within the gamut. Rendering Intent enables you to compress
out-of-gamut colors into the color capability of the press you are
using. You can set any rendering intent value for
RGB
elements by
selecting the required from the
Rendering intent options
list. The
default value for RGB is
Perceptual (photographic)
. The default value
for CMYK is
Relative Colorimetric.
Note: You can also use a virtual printer to adjust job parameters.
