Ensuring color accuracy when you save a file
Color Reference Guide for C9800 - 35
The Frequency and Angle settings in the Application Defined halftone screen are used
regardless of whether the setting for Combine Separations is set to On or Off. For
special instructions for printing separations with Photoshop, see

OTE
:
In general, using halftone screens is not recommended because the print output
will have visible dots of toner rather than smooth blends. Use halftone screens only
when necessary to achieve a specific style of print output.
Ensuring color accuracy when you save a file
You can take the following steps to ensure color accuracy:
• When saving EPS files, do not include PostScript Color Management information.
This minimizes the risk of conflicting data and multiple color conversions.
PostScript Color Management causes your CMYK and RGB colors to be interpreted
by the Fiery as though they were supplied in the Lab color space and, as a result,
processed by CRDs, rather than your simulation settings.
• Include ICC color information in files. ColorWise does not conflict with this
information, and such data is useful for identifying the specific color space used by
your files.
• Do not include halftone and transfer functions.
• Turn off color management in the printer driver.
On Windows computers, if the printer driver offers Image Color Matching options,
select Printer Image Color Matching.
On Mac OS computers, set the printer driver to include
no
color management
commands at print time (see the
Chapter 1
).
