Printing with custom halftone screens

After specifying the halftone screen values for User Screen 1, User Screen 2, or User Screen 3,
select a corresponding custom screen name from the printer driver. Use the same procedure
on page 47 to print a job with a custom halftone screen.
Alternatively, you can send a job with a default halftone screen and change the print
N :
OTE
option setting using Command WorkStation.
The printed job reflects the settings you defined on the Halftone Screens pane.

Supported applications

The following applications have been tested with Mac OS and Windows for compatibility
with the Application Defined setting in the Halftone Simulation print option. Other
applications should work as well, as long as they are using standard PostScript conversions on
halftone screen definitions and the parameters used in the definitions are kept within the
physical limitations of the copier.
• Adobe Acrobat
• Adobe Illustrator
• Adobe InDesign
• Adobe PageMaker

Calibrating for custom halftone screens

When color quality is important, make sure that the Fiery EXP8000/50 is calibrated for the
particular halftone screen you use. Changing a halftone screen usually modifies the color
response of the copier.
The best color is achieved when an Output profile that is associated with the appropriate
calibration response is selected at print time. However, when custom halftones are specified,
the Fiery EXP8000/50 does not have adequate information about the resulting color
response. For this reason, achieving good color with custom halftone screens is often possible
only when you perform custom halftone calibration and use a profile based on this custom
halftone.
Use the following procedure to calibrate the Fiery EXP8000/50 for custom halftone screens.
