Creating a Color Profile 4-23
Profile Settings 26. Enter the Black values for this profile, or select one of the pre-
defined limits (Light, Medium, or Dark; the default is Light).
This allows you to adjust the Black Generation (BG) and Under
Color Replacement (UCR) curves and the grayscale smoothing
curve, and specify the starting point and maximum amount of Black
ink used for a given percentage of black called for in the image.
You can select a preset BG-UCR curve, enter numeric values, or
click the curve to change it.
These black values determine whether any black dots appear in
lighter shades, and the smoothness of transitions in dark shades.
27. Enter the Shadow Range and Black Point Shift, or accept the
default values.
• Increase the Shadow Range to smooth the transitions in dark
areas of the grayscale ramp, decrease to smooth the transi-
tions in the light areas of the ramp.
• The Black Point Shift adjusts the darkest shade (black point) in
the profile. It may be adjusted by ±25% (increase to lighten,
decrease to darken).
28. Enter a file Name for the profile.
For ease of use later, use a file name that includes the resolution,
number of passes, media, and the like. For example:
54xx_1x6_6x6_darkUCR_60shdw.icc
would indicate a 5400 Series printer, one set of six colors, 600x600
dpi, “dark” UCR preset, and Shadow Range of 60.
29. Enter a Description for the profile.
This is the description that will appear in application programs
when you select the profile. The profile cannot be saved without a
description in this field.
30. To create the profile, click the Next ( ) button.
