96 Chapter 13 — The Toolbar | Black Control Point
After a black control point is added to the image, the following options will be available in the B / W / N
Control Point step of the Edit List palette:
Black Control Point Method
Use the black control point method pull-down menu to
switch between controlling only the luminosity of the Black
Control Point or the individual red, green, and blue values.
Luminosity Method
The Luminosity method of the black control point always
changes the color that you have targeted by setting the
black control point to a neutral black. This is often the
most efficient mode to use, as most calibrated printers
work best when the image contains a neutral black. Within
this mode, you are presented with only a luminosity slider
on the black control point and only a Luminosity setting
within the black control point sub-step in the Edit List
palette.
RGB Method
The RGB method of the black control point enables you to set the individual red, green, and blue values of
the darkest color in the image. This option is helpful if your printer requires a non-neutral black. Within this
mode, you are presented with individual red, green, and blue sliders on the black control point and red,
green, and blue entries within the black control point sub-step in the Edit List palette.
3
Adjust the effect of the black control point by either
clicking and dragging the luminosity slider or by
entering a value directly into the text box in the
black control point sub-step of the B / W / N Control
Point step in the Edit List palette.
