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. 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. 96 Chapter 13 - The Toolbar | Black Control Point
