Color Reference Guide for C9800 - 21
Optimizing for output type
The Fiery can be used for on-demand color printing and for color proofing.
On-demand color printing refers to those jobs for which the C9800 is the final print
device. Printing jobs to the Fiery in preparation for printing on an offset press is
referred to as color proofing. Both types of Fiery print jobs can use RGB, CMYK, and
spot colors.
NOTE: 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 Fiery performs
equally well in either environment.
The type of printing you plan for the document—on-demand color printing on the
C9800 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 C9800, 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 Color Guide
Chapter 1).
• 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
affecting color output (see the Color Guide Chapter 1).
Characteristics of on-demand jobs Characteristics of offset proofs
Bright, saturated colors are often desirable. Require the printed colors to match
those from another set of CMYK
printing conditions.
Colors are achieved using the full range
of colors available, referred to as the full
gamut of the printer or, more simply,
device CMYK.
Colors that are specified for an offset press
require CMYK simulation that is optimized
for proofing on the printer.
