Using Color Management Workflows
Optimizing for output type
The Color Server can be used for on-demand color printing and for color proofing.
On-demand color printing refers to those jobs for which the Color Server is the final
print device. Printing jobs to the Color Server in preparation for printing on an offset
press is referred to as color proofing. Both types of Color Server print jobs can use
RGB, CMYK, and spot colors.

The term on-demand applies to producing printed output when it is needed.
You may be familiar with the term short-run, which usually applies to the volume of a
printing task. Although these terms do not mean exactly the same thing, the term
on-demand in this manual applies also to short-run printing scenarios. Because you can
print as many pages as you need and can reprint jobs quickly, the Color Server
performs equally well in either environment.

The type of printing you plan for the document—on-demand color printing on the
Color Server versus color proofing for eventual printing on an offset press—determines
the way you define colors, as well as the print option settings you choose.

• For on-demand color printing on the Color Server, use any application and define
colors in either RGB or CMYK. If your application supports it, you can also choose
colors from the PANTONE color library. Choose the appropriate settings for print
options affecting color output (for descriptions of the print options, see the
colors from the PANTONE color library. Choose the appropriate settings for print
options affecting color output (for descriptions of the print options, see the

• For color proofing, use a PostScript-defined color in CMYK or choose colors from
color libraries such as the PANTONE color library. Placed images can also be
defined in RGB or CMYK. Choose the appropriate settings for print options
