The Paper Simulation white point editing feature lets you customize an
existing CMYK source profile and adjust its white point. You must also link the custom profile with
a specific output profile. When you print a job, you must select the customized CMYK source profile
and its linked output profile to see the effect of the Paper Simulation White Point
editing.
If you want to preserve the existing CMYK source
profile, make a copy of it before editing the white point. You can
copy a profile by exporting it and then importing it with a different
name.
Note: You can edit the white point of a CMYK source profile
but not an output profile.
If you have a spectrophotometer (such as an ES-2000),
you can import measured color values directly. This feature allows
you to target a match based on the actual color of the paper. To
use a spectrophotometer, install and set up the spectrophotometer
before you begin editing the white point.
Note: To use an X-Rite
i1Pro 2, you must use an instrument obtained from EFI.
-
In Device Center, click the
Resources tab and click Profiles.
- Select a CMYK source profile to customize and click Paper Simulation.
- Select the output profile to link with this CMYK source
profile and click OK.
Note: When you print a job with the custom profile, you must select
the same output profile.
-
Make sure that the correct monitor profile for your monitor is displayed under Monitor Profile.
If the correct monitor profile is not selected, select the correct monitor profile in Command WorkStation Preferences.
- To measure a new white point using a spectrophotometer,
click the spectrophotometer icon.
- Place the spectrophotometer in its calibration cradle
and click Calibrate.
Calibration improves the accuracy of measurements.
- Place the spectrophotometer over the target color, making
sure to center the sample aperture over the color.
- Press the button on the spectrophotometer to take the
measurement. The measured CMYK values are imported into the CMYK
fields, and the corresponding Lab values are displayed.
- Alternatively, or additionally, you can edit the Hue,
Brightness, and Saturation values manually.
Hue -
0.0 to 359.9
Brightness -
0.0 to 100.0 (inclusive)
Saturation -
0.0 to 100.0 (inclusive)
Edit the values by dragging the sliders
or typing values in the text fields. The sliders do not show absolute
values. The slider position and associated values are relative to
the paper white definition in effect when you open the dialog box.
View the changes in the preview patch in the upper-left corner of
the dialog box and in the Lab values displayed on the right.
- To print a test page, click Print.
- If the test page looks correct, click Save and close the Paper Simulation
White Point dialog box.
