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.
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
Note:
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
).
