Adobe Acrobat DC - print is "blacked out" where it should be shaded

THE PROBLEM

All of the shaded areas are printing a solid black when printing an Adobe document.

THE SOLUTION

Select Print, then the Advanced button. Under Color Management, scroll nearly to the bottom of Color Profile. There you'll find "Working RBG: sRGB IEC61966-2.1." Select this, then, OK, then Print.

This should resolve the problem.
