For particular purposes you may want to adjust the process component percentages for individual process colors. If you find that a supposedly pure cyan object is generating separation percentages in other process colors, for example, you can redefine the process separation percentages for that color to give the separations you require.

To do this choose Pen Color or Fill Color from the Draw menu and select the Other. In the Color Selector dialog box, click in the scrolling list on the process color to be adjusted, then click on Custom Color. In the Custom Color dialog box, click the CMYK radio button and adjust the sliders or type values in the CMYK boxes to give the required percentages. Leaving the CMYK radio button still selected, click OK in both the Custom Color window and the Color Selector dialog box.
