Managing Color in PostScript Applications
Color Reference Guide for C9800 - 34
Using CMYK simulations
You can specify a CMYK Simulation profile and a CMYK simulation method for a job
using the CMYK Simulation Profile and CMYK Simulation Method print options
(see the
Chapter 1
). The CMYK Simulation setting affects all CMYK
color data sent by the page layout or illustration application. It can also affect RGB
data sent to a page layout application if RGB Separation is set to Simulation.
• If the document contains CMYK graphics that were separated for an offset press
standard, apply the corresponding CMYK Simulation setting. For example, for
graphics separated for
, choose SWOP as the CMYK Simulation setting.
If you print separations to the Fiery and choose to use the Combine Separations
feature in conjunction with Full Simulation, the result may not match that of the
same page printed as composite.
• If the document contains CMYK graphics that were separated according to the color
characteristics of a custom
(not a press standard profile), specify the
corresponding profile as the CMYK Simulation Profile setting on the Fiery.
For more information on downloading CMYK Simulation profiles to the Fiery with
ColorWise Pro Tools, see the
Chapter 3
.
Using application-defined halftone screens
If your site has installed the Fiery Graphic Arts Package (not available for all Fiery
models), you can define halftone screens from several PostScript applications and use
them when printing. The results vary depending on the application.
To define a halftone screen, use the application to adjust the Frequency and Angle
values of the halftone screen. For applications that use the Fiery default (InDesign,
FreeHand, QuarkXPress, and Illustrator 10), the ink dots are round; for applications
that define their own shape and do not use the Fiery default (PageMaker, Photoshop,
and Illustrator 9),the halftone dots may be a different shape. When you print the job,
choose Application Defined for the Halftone Screen print option.
