22. Using ColorWise Pro Tools
4. For a simulation profile, choose Master from the Edit Mode menu. For
an output profile, choose Custom from the Edit Mode menu.
You can use the dialog box to view or edit profiles. The graph allows
you to view and manipulate color output values.
When editing an output profile in Custom mode, the Import button at the bottom
of the color Editor window lets you import a calibration target file (.trg) created
on another Fiery using the previous version of ColorWise. The current version
of ColorWise does not allow you to save a target separately; rather, it saves the
target in conjunction with and output profile.
5. Select the colors you want to edit by turning colors off and on.
The box with the eye icon to the left of each color indicates whether that
color is visible on the graph and will be affected by changes to the
curves, brightness, and dot gain controls. You can view and edit all four
colors (cyan, magenta, yellow, and black) at once or any combination
thereof. Working with only one or two colors at a time helps you fine-
tune your adjustments. To turn off a color, click its eye icon. In the
example below, cyan and magenta are visible and can be edited.
6. Click Dot Gain to adjust the dot gain value for simulating press output.
You can choose either the North American or European standard. Then
use the sliders to select the desired Dot Gain:
The range of values for North American at 50% input are from 0% to
50% gain on output.
The range of values for European at 40% input are from 0% to 59%
gain on output; the range of values for European at 80% input are
from 0% to 20% gain on output.
If you use Dot Gain values, you should apply the settings first so that the
curves are deflected from their straight-line positions. Then make edits
to the new curves. When you adjust Dot Gain values, all existing points
on the curve are removed. A warning dialog box gives you the chance
to cancel Dot Gain settings before they are applied.
7. Use the plus and minus buttons to adjust brightness.
Changes to the brightness are reflected in the curve(s).
8. You can adjust the curves directly by clicking and dragging points on the
curve or by entering numbers into the input and output boxes.
The graph maps the input percentage to the output percentage. (These
percentages refer to the size of the CMYK halftone dots). The curve you
selected appears, and points along the curve are marked so you can
adjust them.
You should adjust points in this way only after you have entered the Dot Gain
and Brightness values.
