Spot colors and blending modes
Using spot colors with certain blending modes sometimes produces unexpected results. This is because InDesign uses process color equivalents on-screen, but uses spot colors in print. In addition, isolated blending in an imported graphic could create knockouts in the active document.
If you use blending, check your design periodically using Overprint Preview in the View menu. Overprint Preview gives an approximation of how spot inks that overprint or interact with transparent objects will appear. If the visual effect is not what you want, do any of the following:
Use a different blending mode or no blending mode. Avoid these blending modes when working with spot colors: Difference, Exclusion, Hue, Saturation, Color, and Luminosity.
Use a process color where possible.
